Anyone who has used Paxil to control anxiety... Feedback please?

Did it help? Did it not work? How were the side effects? Were you able to ween off of it fine? After you quit did you start having anxiety problems again or did it help you long term?





Anything additional please add.





I've always been sort of anti-drugs/pills when it comes to all these pills on the market, but my anxiety has gotten so severe that pills cant make my life any worse if you know what I mean. So I'm currently debating Paxil, I was told by my doctor after I explained this to him, that Paxil has hardly any side effects and hes never had a patient thats had a bad reaction to it.





And please, don't respond unless you've taken it, or known someone that takes/taken it. Thx :)Anyone who has used Paxil to control anxiety... Feedback please?
Hi,





Both my sister and I were put on Paxil in high school for anxiety and depression. And we both got off of it as soon as possible.





For me, it did make me feel ';foggy'; all the time, as well as dizzy or lightheaded and just generally ';blah.'; I was 14 when I started taking it and I was on it for about a year before switching to another med. I remember after being on it for a month or two, I was at the movie theater with some friends and I was telling them I didn't feel right because I was on this medication called Paxil. And this lady sitting in the row in front of me turned around and said ';Did you say Paxil? I'm sorry to interrupt, but I was on that for years and it was a nightmare. Get off it as soon as possible and switch to something else.'; The lady's husband was nodding his head in agreement and it scared me so much I asked to switch meds. My mom and doctor said to ';give it time,'; so I did, but I never found relief from it. There's no medication in the world that will ';fix'; everything. Once you come off a medication, you will be exactly the same as before unless you've changed other things (learned new coping skills for your anxiety, dealt with any underlying issues, etc.). As for weening off, I don't really remember the process except that I felt like total crap during it. Paxil can cause really uncomfortable flu-like symptoms. I remember the movie theater lady telling me she was sick in every way for several weeks while trying to come off.





Paxil causes many side effects for many people. I ended up on a huge mix of meds over the next few years (the one that stuck was Prozac and Zyprexa) and really never felt ';right.'; I finally got off everything about 5 years ago and have never felt better. I know that's not the case for everyone, but I found that taking the meds while in rigorous therapy was the answer. Eventually we have to learn to cope with our anxiety without needing medication. It just makes life easier. Unless you want to be on meds your whole life... My sister has ended up on a horribly debilitating cocktail of meds because she refuses to deal with anything in therapy. She's currently on high doses of Prozac, Wellbutrin, Lamictal, Abilify, and Provigil. She is literally a shell of her former self, like a walking zombie. It's really sad.





I'm not trying to scare you! Sorry! I just hope you seek help with a therapist as well, not just a psychiatrist. I hope you find some relief over the next few years, hang in there...Anyone who has used Paxil to control anxiety... Feedback please?
I took paxil for depression. It worked very good with few side effects. The problem I had while taking it was the inability to ejaculate. It took a long time to achieve orgasm or not at all. If you do stop taking the drug it is recommended to gradual reduce to dose and not stop it suddenly.
After being in and out of rehab several times I have found paxil to be the best for me but ask a dr cause I don`t know anything

Whats is the best pedal to control feedback?

This is gettign redicuolous!!!!!!! the feedback is out of hand. I have an esp explorer, and i use emg hz pickups, and i run it through a Boss Reverb, Digitech Whammy, and a shure wireless system. I WAS running it through a pedal called ';hush system the pedal';( really old pedal that cuts you of and gives you NO sustain)





does anyone know of a noise gate that......


1. Cuts of all feedback when its really loud


2. Doesnt rape the tone too badly


3. Keeps amps natural sustainWhats is the best pedal to control feedback?
Boss makes a pretty good one. It doesn't work miracles, but if you're setup is within reason, it should do the trick.

  • Know the mechanisms of hormonal control (positive and negative feedback, antagonistic hormones).?

    I really don't understand it, it's not Homework btwKnow the mechanisms of hormonal control (positive and negative feedback, antagonistic hormones).?
    Hormones are chemicals that run throughout the body and lead other organs to produce reactions. Positive and negative feedback has to do with feedback inhibition mechanisms, where the presence of the product of the reaction directly affects later reactions of the same type by affecting the hormone that started it all.





    In a negative inhibition case, the body either produces hormones to counter reactions that are going on or it stops producing the hormones that are causing the reactions. Most feedback inhibition instances in the body are negative. See ';trp operon'; for an example of a gene feedback inhibition.





    In a positive feedback case, the body produces a hormone which leads to a reaction. The product of the reaction causes more hormone production, which causes increased product, which causes increased hormone, etc. Obviously, positive feedback cases never spontaneously stop, so they are only used when the cells are not permanently part of the organism. The best example is in plant hormone ethylene and ripening fruit. Ethylene makes fruit begin to ripen. The presence of ripened tissue increases the amount of ethylene, which increases the ripening and so on until the fruit is so ripe, it falls off the plant. Another example is oxytocin and the formation of endometrial wall in the uterus.





    Antagonistic hormones are pairs of hormones that produce opposite results at different times, depending on what your body needs. A good example is blood sugar level. When sugar conent is high in the blood, your pancreas produces insulin, a hormone, to cause cells to take up the sugar and therefore blood sugar levels drop (until you eat more sugar). (Lack of insulin means cells cannot take up the sugar which leads to diabetes.) If there is not enough sugar in your blood, your pancreas produces glucagon, a different hormone that causes your organs to release stored sugar in order to increase the blood sugar level. Therefore: insulin= decrease in sugar level; glucagon= increase in sugar level: antagonistic hormones.

    Explain the negative feedback loop that allows kidneys to control the solute-water balance of the blood?

    Please post answer before MONDAYExplain the negative feedback loop that allows kidneys to control the solute-water balance of the blood?
    Urine composition and the rate of urine formation are largely regulated by hormones vasopressin, aldosterone, and angiotensin, and the enzyme rennin.





    Vasopressin (ADH) is produced by the posterior pituitary gland and increases the bodies ability to resorbtion of water. it increase the permeability of the collecting ducts.


    Diabetes insipidus is caused due to a lack of this hormone. It is characterized by thirst, and the production of large amounts of dilute urine.





    Angiotensis and Aldosterone are hormones that regulate the amount of sodium that is resorbed from the filtrate in the nephrons. Aldosterone is produced by the adrenal gland. it promotes the resorbtion of sodium by the distal tube. Its action is directed by the bloods salt content. The kidney secretes an enzyme rennin, which changes a plasma protein angiotensinogen into angiotensin, which helps to increase the production of aldosterone and the blood pressure of the kidney.

    What should happen in a temperature control system using negative feedback when the set point is decrease?

    close loop systemWhat should happen in a temperature control system using negative feedback when the set point is decrease?
    As long as the set point isn't decreased outside the operating range of the loop so that it can maintain lock conditions, the loop should track the temperature down and maintain lock at the new set point.

    Looking for feedback on your Nuvaring experience: was it effective as birth control?

    I just started using the nuvaring , my first month .. but i must say I'm MUCH more confident about the ring . I always forget to take pills.. the patch kept falling off ..


    I like this because i can put it in .. set a alarm on my phone or even the nuvaring website has timer you can put on your computer so it will remind you to take it out and when to put it back in ,, SO easy


    I had No real bothersome side effects .. maybe more discharge but they say that's normal ..


    i cant feel it during sex .. my man says he can feel it with his fingers .. and a little bit during intercourse but it's not Annoying ..


    I've hured of it coming out during sex (but hasn't happened to me )


    I do recommend this method . so far so good i love it . always check with your doc or Gyn before starting about any heath things you have .. and remember *even tho i think this is common knowledge and silly to have to always say * but.. ring doesn't protect from Std's AIDS etc ... so AGAIN .. USE condoms .. use common sense ... OK I've rambled on long enough .. hope it's helped you ..


    good luckLooking for feedback on your Nuvaring experience: was it effective as birth control?
    i love the nuvaring, mostly for convenience. i could never remember to take pills everyday. when inserted properly you can not feel the nuvaring, nor should it fall out.


    i don't use it for birth control, i use it because i do not get my period, and i need the hormone replacement. (i use it to set myself up for fertility medication.


    i find that it has the lowest amount of side effects compaired to other oral pills i have tired.


    i would assume that using it as prescribled that it would be effective, as long as you don't forget to put it in after your week of rest.


    hope this helps.

    What effects are created by the negative feedback system controlling digestion once chyme has left the stomach?

    A negative feedback loop occurs in which the low pH of the stomach inhibits gastrin secretion by the G cells which results in less acid secretion.





    Gastrin release is inhibited by:





    鈽籘he presence of acid (primarily the secreted HCl) in the stomach (a case of negative feedback).





    鈽籗omatostatin also inhibits the release of gastrin, along with secretin, GIP (gastroinhibitory peptide), VIP, glucagon and calcitonin.





    One inhibitory factor is acidity (pH below 3) - a negative feedback mechanism, exerted via the release of somatostatin from 未 cells in the stomach, inhibits gastrin and histamine release.





    Another inhibitory factor is somatostatin, which acts on somatostatin-2 receptors on G cells in a paracrine manner via local diffusion in the intercellular spaces, but also systemically through its release into the local mucosal blood circulation; it inhibits acid secretion by acting on parietal cells.





    Other inhibitory factors are gastric inhibitory peptide (GIP), secretin, somatostatin, glucagon, calcitonin, all of which are released into the circulatory system.





    Chemoreceptors in the stomach monitor the pH level of the chyme, and trigger the negative feedback loop. Nerve impulses propagate to the submucosal plexus, where they innervate parasympathetic and enteric neurons. During the intestinal phase of digestion, gastric peristalsis and secretion of gastric juice are inhibited.

  • I just started the Yaz birth control. Can anyone give me feedback on their experiences with this pill?

    I would recommend yasmin to almost anyone. Most of my friends are on it and I use to take it. I started on Levlen, and slowly gained a little weight and found that it was harder to control. I then switched to Yasmin and lost all the weight I had put on from levlen, most of my friends have had similar experiences. Yasmin is the pill with the one lowest levels of hormones, so it doesn't mess with your body as much, highly recommend itI just started the Yaz birth control. Can anyone give me feedback on their experiences with this pill?
    It works with no problems, remember take them everyday or they won't work. I've taken them for 25years. All good! P.S. I'm Jeff's wife.

    Positive and negative feedback controls in homeostasis?

    i have to decide if becoming thirsty when you are dehydrated is positive of negative feedback. from what i understand, negative feedback is when orders are put out to reduce a stimulus, so thirst would be negative. im not sure exactly what negative feedback is and im completely don't know what positive feedback is. can someone please explain them to me and answer if thirst is positive or negative?





    thanks!Positive and negative feedback controls in homeostasis?
    I think that it would be negative also because it is reversing the the current condition.


    Positive feed back is when something is being produced, a signal is sent to produce more of that product.


    Negative feedback is when the a product is produced causing a signal to be sent to stop it's production.Positive and negative feedback controls in homeostasis?
    I think it is negative because it is bad if you are dehydrated.

    c. the transformation of the cells of the ruptured follicle into the corpus luteum


    d. the high level of estrogen that causes the anterior pituitary to release a surge of LHWhich of the following interactions is an example of a negative-feedback control system...?
    d is an example of positive feedback so that is out





    b seems more likely an increase in estrogen will decrease LH secretion since their is more estrogen in the bloodstream which might in turn have an effect on FSHWhich of the following interactions is an example of a negative-feedback control system...?
    Answer is (B) but again we should know why :


    Negative feedback loops resist change by sensing a stimulus . For example, a negative feedback within the brain of a bird or mammal (Whale for example) a small region above the roof of the mouth called the hypothalamus is a biological thermostat. The hypothalamus has a genetically determined ideal temperature for body (e.g., in man about 37掳C or 98.6掳F), Specialized hypothalmic nerves measure the temperature of body through the brain while other nerves analyse arriving messages from temperature sensors in the skin (the hypothalamus then triggers the mechanisms of producing heat). When the temperature of the body drops below a certain point, the hypothalamus signals effectors, the muscles, to begin to contract. At first, of these contractions are small and occur at different times in different muscle. As the signal increases, muscle cells begin to fire messages in synchrony and the individual begins to shiver. These contractions generate heat and thus help to counteract the initial stimulus. If the environment is too cold body cannot keep up with heat loss, hypothermia may set in lowering the internal temperature is sensory confusion and ultimately leading to death. If, on the other hand, environmental temper ature is high, the individual can experience hyperthermia-high body temperature which can be damaging or even fatal.


    While negative feedback loops resist internal change, positive feedback loops bring about rapid change.

    Negative feedback control of sex hormones can be found at two levels: _________.?

    Negative feedback control of sex hormones can be found at two levels: _________.





    a) The cerebrum signaling the hypothalamus as well as the anteriopr pituitary secreting gonadotropic hormone


    b) The hypothalamus secreting the relasing hormone as well as the anterior pituitary secreting gonadotropic hormone


    c) The thalamus secreting releasing hormone as well as the anterior pituitary secreting growth hormone


    d) The anterior pituitary secreting gonadotropic hormone as well as the adrenal cortex secreting releasing hormone.Negative feedback control of sex hormones can be found at two levels: _________.?
    Lil Butterfly,


    Your answer is “D”, because the neurons in the hypothalamus secrete gonadotrophin-releasing hormone (GnRH), which is transported through local blood capillaries to the nearby anterior lobe of the pituitary gland. The whole cascade of hormone secretions, from the hypothalamus to the anterior pituitary gland to the gonads, is tightly controlled by feedback effects of the gonadal steroids, which in turn act on both the hypothalamus and the pituitary gland to regulate the secretion of GnRH and of gonadotrophins. In the male these feedback effects are always negative. This means that when secretion of the male hormone, testosterone, increases, the release of GnRH and luteinizing hormone - LH will decrease — inhibited by the rising level of testosterone in the blood.





    Hope this helps

    An example of homeostatic control through positive feedback in HUMAN SYSTEMS ?

    A nerve impulse (action potential) in a nerve builds to its peak through positive feedback--the opening of sodium channels causes in influx of sodium which causes the inside of the cell just under the membrane to become less negative, this causes more sodium channels to open, more sodium enters, the inside becomes even more less negative, that causes more channels to open, etc......An example of homeostatic control through positive feedback in HUMAN SYSTEMS ?
    Positive feedback amplifies changes made by a stimulus, in other words, it maximizes the effect of a stimulus. An example of positive feedback would be childbirth, where contractions (through the use of the hormone oxytocin) are intensified until the child is out.

  • How do I get good controlled feedback on my amp?

    I want to get it fairly controlled.... and as much as I can!How do I get good controlled feedback on my amp?
    When you say controlled feedback, I'm assuming that you're referring to the technique where the acoustic output of your amplifier is exciting either the root note or a harmonic related to the pitch you're playing.





    High gain is part of the equation. The compression that happens when a tube is overloaded is the other part.





    Compression is a tool that's used in every recording your ever heard. Think of it as an hand on the volume control of your amp. It turns down the very loud parts and turns up the very soft parts. Technically speaking, it reduces the dynamic range of the signal, and helps it cut through a mix of instruments.





    The other part of the equation is the acoustics of the speaker, the room, and the instrument itself. Different woods will want to feedback at different frequencies.





    Position is not always directly in front of the amp (unless all you're looking for is a high pitched squeal). You'll probably need to face the amp, but changing the angle of the guitar in relationship to the speak can produce diffent pitches of feedback.





    I had a chance to work on a local crew for a Santana show a few years ago. During sound check, Carlos would walk around the stage to figure out where different notes would feedback. He's have his guitar tech mark those locations with what notes for feedback there.





    Short of volume/distortion/compression, there is a device called a Sustainiac that can be installed in your guitar to give you this effect. It replaces the neck pickup, and actually provides a magnetic drive signal to keep the string vibrating. This let's you get the feedback effect at any volume level.





    http://www.sustainiac.com/





    Finally, DO NOT use unpotted pickups. Unless, again, you're only looking for a high frequency squeal.





    Good luck.





    Greetings from Austin, Tx





    KenHow do I get good controlled feedback on my amp?
    Use a lot of gain, like a distortion pedal run into a distorted amp. Use an un-potted humbucker pickup. Stand with the pickups facing the amplifier's speakers. Get ready to look for a new place to live.
    Low volume move body of guitar close to amp





    Lots of highs and mid's turn the amp up till you get some :)





    Enjoy!

    Are you against gun control or you for it? Please give me your feedback?

    For those in California, I strongly wish for your feedback. I'm putting a survey together and would like to get some feedback from those people. if you are not in California, can you tell me waht state your in and what your gun laws are and what you feel the problem is and how it should be solved.





    Thanks a millions!Are you against gun control or you for it? Please give me your feedback?
    Against it.





    Castro - Hitler - Stalin all for it.





    When the government knows where all the guns are - they know where to go to take them away. A well armed society is a safer society.





    A well armed society will not be tyrannized by a wayward government.Are you against gun control or you for it? Please give me your feedback?
    I'm from Upstate New York.





    With the exception of laws making possession of a gun by convicted felons and those persons with a documented mental illness illegal ... I am totally against gun control laws!





    The problem with gun control laws is fairly easy to see ... the people who would use a gun to break other laws will not care if they are violating gun control laws too!





    The solution is also fairly simple. If the government can not show that the applicant has a violent criminal past (including domestic violence), or has a mental illness (including drug or alcohol dependency) they should be required to issue a gun owner's permit. That permit should be valid as a concealed carry license until revoked, with the only reasons for revoking the permit being documentation of a mental illness or violent criminal offense.





    No firearm should be illegal to own based on it's look, action or capacity, including full auto firearms!





    Once we level the playing field with the criminals of society ... the honest citizen having access to firepower equal to the criminal's, you can bet the violent crime rate would drop like a broken elevator!
    I live in California. I'm against most gun control. I whole heartedly support an instant background check for every single gun transfer, to make sure the buyer is not a criminal or kook. But other then that, I believe most of the gun control laws we currently have or are being proposed are completely ineffective or unconstitutional.





    A recent example, the gun control proponents are pushing for recording of ammunition purchases. We already did that before. It was stopped because it never once solved a crime. Now it's back.





    Gun registration does nothing to prevent crime, but it sure provides a handy list for those wishing to seize guns at a later time.





    Waiting periods can help, but can also do harm. I've read more then one story of people, usually women, who believed their lives were in jeopardy, the cops unable to help, and were unable to get the gun in time to prevent some psycho ex boyfriend/husband from killing them as they waved the restraining order in his face.
    I live in Crook County IL where King Richard the Nimrod and his court jester Jessie Jackson reign.





    The problem I have is that even though gun control was to slow down gun crimes and limit criminals, only those who are law abiding will follow. Criminals are criminals because they break the law. So gun control only limits the legal, responsible, and law abiding firearm owners.





    Also, Chicago has a higher homicide rate than this time last year. Homicides in Chicago are majority gun related. Yet Chicago has a handgun ban in city limits. That is the most strict gun law out there. So if gun bans work, why is Chicago in such deep doodoo when it comes to violence.





    Now I am not effected directly by Chicago laws but Crook County is defiantly not gun friendly and if they could would adopt stricter gun laws (too many on the books to list).





    My main question is this. There are 48 states that allow conceal carry. Why don't they have the problems Mayor Daley spoke of after the recent Supreme Court ruling on the 2nd Amendment.
    Arizona - has very few gun laws.





    I am against gun control, and I feel there is no problem living in this state. Crime does not seem to be a major issue in Phoenix and Tuscon and other major cities here as it does in CA cities (I'm not saying there is no crime here, it's just not as much as LA or other 'gun control' cities).





    My personal belief is that gun control just increases crime with guns. Criminals will always have guns, no matter what you do. I would rather be in a place where a criminal is afraid to commit a crime due to fear of civilians may be carrying guns, than live in a place where criminals know no one can stop them from commiting a crime. It's just safer to have guns available than to ban them.





    Actually, I believe that everyone above the age of 18 should be required by law to carry a concealed gun on themselves. Yes, there would still be violence and deaths initially, but eventually people will realize that they could die very easily if they piss someone else off, so idealy people will start to be more civil towards each other, and crime rates would drop...





    As people like me like to say, 9/11 would never have happened if guns were allowed on planes. Someone tries to kijack it, and every other passenger shoots the terrorists on site. Problem solved.
    I am in favor of strong, sensible gun control. The US has the weakest gun laws in the industrialized world, and also the most crime of any comparable country. You would have to be blind to think there is no connection.





    The problem is that people are unable to distinguish between gun rights of law-abiding citizens and gun rights of criminals. For example, the NRA says they are against criminals having access to guns, but whenever a law comes up that would block access to guns for criminals (such as background checks at gun shows before buying a gun) they oppose it.
    Obviously we have to have some limitations and processes related to gun use and ownership. We can't have Bob Joe hunting deer with a rocket launcher. I don't think anyone would object to a certain level of limitation on gun ownership.





    I don't like guns, but if the people who own them are intelligent and safe in their use, then I don't have a problem with it. It's the idiots out there with guns that worry me. I think people should have to pass a thorough examination before being allowed to own a gun because safety is more important than your right to bear arms.





    Just as we can take away someone's right to freedom by jailing them after a crime, I think we can take away other rights like owning weapons. If you can't behave, then you can't have a gun, at least for violent offenders.





    And I hate that stupid saying ';only criminals will have guns';. You know what? That's better than all the idiots in the world having guns, so I'll take my chances.





    Those are my thoughts.
    FL here...





    Guns are not just a right, but a possible requirement if ever you have to defend your country from enemies foreign or domestic. The governent should never have ALL of the firepower.





    However, there should always be reasonable regulations that help keep the public safe. I support the 5 day waiting period (cool off period) before you can recieve a handgun from a dealer. Convicted felons cannot and should not be able to legally carry guns. You shouldn't be able to own a military grade weapon unless you are in the military. I believe guns should have to be registered the same way you register a car...e.g. a gun title...which should be free of charge. You should have the right to conceal a weapon anywhere, as long as it's not a school, government building, medical facility, bank, or any place/event that sells alcohol.





    Responsible, law abiding people need to arm themselves. Criminals already have guns.
    NC here.





    Gun control is extremely short sighted. Only law abiding people are going to follow the law. The fact is that criminals are responsible for crime not guns. We need to quit playing with these people and lock up violent offenders........that would help cut crime, not worrying about how many guns I have in my home. I've owned a gun since I was a little kid and I have yet to rob a liquor store or hold someone up on the street.





    Look at this idiotic places that have gun control and check out their crime rates. It just doesn't work.





    I'm a law enforcement officer and I'm all for law abiding people owning guns.





    Nope in 2008.
    I'm for gun control, but not total elimination of guns. I do agree that people, in general, have a right to own a gun. But I do not agree that they have a right to own a gun without limitations set to protect citizens (and especially children) from idiots and criminals. For example, I believe that guns should be required, by law, to be locked safely to protect children. If a child uses your gun to harm someone, YOU should be punished for it for not keeping that gun safely away from them. I also believe that limitations should be placed on who can own a gun, and what kind of gun they should be allowed to own. The Founding Fathers had muskets in mind, not uzis, when they wrote the Constitution. Considering that we have a standing army and navy now, and organized law enforcement, the militia-element of the second amendment is obsolete. Our laws should reflect this, as well as common sense. If you want a gun, fine. But there is absolutely no excuse for fighting against common sense means of keeping people safe. The fact is that the average gun owner is not qualified to police their neighborhood. I, for one, would feel a lot safer if they kept their freakin' guns in a locked cabinet where they belong until they have time to go hunting or to the gun range, where guns actually belong.





    p.s. Wow. I thought the pro-gun people would come up with a LOT better and more logical arguments than this! You really think that your handgun is going to protect you from the government!? OMG, LOL!!!!! That is freakin' hilarious!! And who is going to protect me and my family from a crazy nut that actually believes this baloney? And you really think that 9-11 would not have happened if guns were allowed on planes? That is equally crazy, because of two things:





    1. The terrorists would have had guns, and everyone would have been dead before you could have done a thing about it.





    2. Four planes were crashed in the 9-11 attacks. All it takes is a single bullet hole in the fuselage of a plane to potentially bring it down. So how many times has some crazy guy went into MacDonalds or the Post Office to blow people away? Now put those guys on a jet airliner. Four planes crashed in 9-11 is not as big a deal as losing an airliner full of people a dozen times every year because of nuts on jets with guns. you don't trust the government? Well, I don't trust YOU. Fair enough? I think so. What a weak argument.





    Now let's consider the ';crime would go up if only the criminals had guns'; argument. Few civilized nations in the world have as lenient of gun laws as the United States. And yet, the United States is one of the leaders in gun violence in the entire world. That's a fact, although I am sure you'll deny it. (The NRA has made up statistics before, and I am sure they will do it again). Compare that to Britain or Germany, where people are not allowed to keep guns in their homes. LOL! the only nations with more gun violence are the ones with LESS lenient gun laws. Take a look at the Middle East, for example. What a pathetic argument in favor of more guns in the hands of citizens.
    An armed society is a polite society. Nobody would dare vent their road rage or try a drive by shooting if they knew more than likely every one they can see is packing a pistol JUST like they are. Criminals give less than S#%t about laws. The ONLY people affected by gun laws are the LAW ABIDING citizens. Look at all the numbers out there - not people's FEELINGS about this issue. The numbers say over and over - LESS gun control equals less crime. The tighter the gun controls on the average citizen, the more apt criminals are to use guns during a crime. Ask yourself this; when I dial 911 do I want to bet my LIFE the responding officers are on the job or hanging out at the Dunkin Dough-nuts?





    I live in New York (up state) After 31 yrs in law enforcement, New York took nine months to approve my pistol permit... Do you think that inspires confidence in me or any law enforcement folks that know about it that we are being treated fairly by our government? I know that the red tape is designed to discourage law abiding citizens from even trying to get the required permit when the constitution GUARANTEES they are authorized to possess a gun. Why do you think they made it the SECOND right in the Bill of Rights?
    I live in Phoenix Arizona. Every morning I switch on the tv for the news and every morning there is the usual list of shootings. Most are drug related or house invasions where one or more invaders are shot dead. As long as these mental midgets are killing each other or being killed by legally owned guns that's ok by me. I'm against gun control.
    I live in VT. I don't have a gun, so I'm not really sure what the laws are.





    I am for gun responsibility, though. I think if you have a gun, it is your responsibility that it doesn't kill anyone. This means if you leave your gun sitting out on your kitchen table and someone comes along and picks it up and kills somebody, you are responsible (as well as the shooter, of course).
    they could tweak it to include medical backgrounds on mental disease.that is the only thing i would even remotely consider to change.this though is a violation of your right to privacy. so i really don't see that changing anytime soon.nor do i really think it should.i live in pa. and we have a good system of checks and balances here.i believe if you are able to own a firearm .you should be able to get it after the waiting period.
    I am against gun control for one simple reason, government will not always be there to protect you. When government wants you to give up your gun, the implicit promise is that it will always be there to protect you. Do you think it can? I don't.
    I live in Philly we don't really have gun control laws but we defiantly need them there is a 48 hr window for purchasing a weapon. They have tried to use incentive programs for turning in weapons as far as free sixers tickets or cash.
    I'm in California. I'm against gun control.





    I think when the founders spoke of the right of the people to keep and bear arms, they meant it. And I think guns are the only way weak people can protect themselves from strong people.



    Against gun control..


    I mean.. saying guns kill people is the equivalent of saying pencils misspell words. Somebody has to pull that trigger.


    I am from Nebraska..we don't have very strict gun laws.
    Since true gun control is hitting your target








    I am 100 percent in favor of it








    I am in Arkansas
    I don't own a gun, and don't want one. But I think gun control is a hollow cause. Gun control laws won't stop criminals from having guns, and they're the ones that cause the problems.





    But the arguments used to defend gun ownership are flawed too. There really is no constitutional right to personal firearms, the constitution provides the right to own arms for use in a well regulated militia.. AKA a state army.





    I'm from PA, but as a non-gun owner I don't know the laws in the state.

    Guitar Feedback control?

    Describe how a negative feedback mechanism can help control a metabolic pathway.?

    A negative feedback mechanism would inhibit the production of a hormone such as insulin or glucagon. If the blood sugar level rose to high the mechanism would inhibit glucagon release and cause release of insulin.Describe how a negative feedback mechanism can help control a metabolic pathway.?
    negative feedback is when the product of a reaction comes back and inhibits its own production. Lots of things are regulated this way. The first step in the glycolytic pathway is regulated by negative feedback. Hexokinase catalyzes the production of glucose-6-phosphate from glucose. However, glucose 6 phosphate inhibits hexokinase. So hexokinase stops until g6p is depleted, and then it can make more.

    What is the deffernce between feedback and feed forward loop in process control?

    I would be so happy if you provide some diagrams or suitable links having diagramsWhat is the deffernce between feedback and feed forward loop in process control?
    Feedback is where you are measuring the variable that you are trying to control, and then using that info to control it.





    Feedforward is where you measure some other related variable, and then use it to control the control variable.





    Best example: Driving.





    When you drive you try to maintain a certain distance from the car in front of you. Your eyes ';measure'; that distance and if they notice that the distance is shrinking your brain uses that information to have you slow your car down to get back to the initial distance. Feedback.





    Say that you are driving, and the person in front of you uses their brakes. That causes the distance between the two of you to get smaller; so you could measure it with the feedback loop of eyeballing the distance and noticing that they are getting closer to you. Or, if their brake lights are working, you notice that the LIGHTS are on. Which has nothing to do with the distance between the cars, but you know that brake lights ON means that the person in front of you is slowing down. Feedforward.





    It all has to do with the relationship between the variable you are trying to control, and the variable you are measuring.

    A) ATP attaches to the active site of the enzyme

    I need a feedback loop indicating how the rate and depth of breathing control pH of Blood!?

    I have a diagram to fill out, so I need receptors, a control center, effectors, and a normal.I need a feedback loop indicating how the rate and depth of breathing control pH of Blood!?
    Unconsciously, breathing is controlled by specialized centers in the brainstem, which automatically regulate the rate and depth of breathing depending on the body鈥檚 needs at any time. When carbon dioxide levels increase in the blood, it reacts with the water in blood, producing carbonic acid. Lactic acid produced by anaerobic exercise also lowers pH. The drop in the blood's pH stimulates CHEMORECEPTORS in the carotid and aortic bodies in the blood system to send nerve impulses to the respiration centre (=CONTROL CENTRE) in the medulla oblongata and pons in the brain. These, in turn send nerve impulses through the phrenic and thoracic nerves to the diaphragm and the intercostal muscles (EFFECTORS), increasing the rate of breathing. This automatic control of respiration can be impaired in premature babies, or by drugs or disease.

    What kind? If its Mirena. It has a hormone in it. Most women are very pleased with this type of birth control. The period stops and it requires no thought. If its paraguard then there are no hormones in it. This device is used to make the uterus uninhabitable for a pregnancy. meaning you can conceive but the pregnancy can't implant in the uterus. with this type you may have months of a regular cycle and some months where the cycle is heavier.


    When the IUD is inserted there is a string that connects to it. the device is placed into the uterus but the strong hangs through the cervix and into the vagina. The string has to be checked after your period because during the period the cervix opens a bit and the iud can fall out. doesn't happen often but its possible. that's why you have to keep it checked

    Explain negative feedback control of body temperature?

    using thermoreceptors, the hypothalamus, %26amp; the temperature control center.Explain negative feedback control of body temperature?
    The relatively constant conditions within organisms, or the physiological processes by which such conditions are maintained in the face of external variation.





    Similar homeostatic controls are used to keep factors such as temperature and blood pressure nearly constant despite changes in an organism's activity level or surroundings. Such systems operate by detecting changes in the variable that the system is designed to hold constant and initiating some action that offsets any change. All incorporate a sensor within the system that responds when the actual condition differs from the desired one, a device to ensure that any action taken will reduce the difference between actual and desired, and an effector to take the needed action as directed. The crucial aspect is that information is fed back from effector to sensor and action is taken to reduce any imbalance—hence the term negative feedback.


    Body temperature in mammals is regulated by a sensor that consists of cells within the hypothalamus of the brain. Several effectors are involved, which vary among animals. These include increasing heat production through nonspecific muscle activity such as shivering; increasing heat loss through sweating, panting, and opening more blood vessels in the skin (vasodilation); and decreasing heat loss through thickening of fur (piloerection) and curling up. Humans sweat, but they retain only a vestige of piloerection (“goose flesh”).





    While the homeostatic mechanisms described involve the neural and endocrine systems of mammals, it is clear that such arrangements pervade systems from genes to biological communities, and that they are used by the simplest and the most complex organisms.

    How does the negative feedback system work to control hormone levels in the blood ?

    please help !!!!!!How does the negative feedback system work to control hormone levels in the blood ?
    When some hormones are secreted in your body, they are done so by signalling hormones.


    For example





    Your pituitary gland in your brain secretes TSH (thyroid stimulating hormone). As the name lets you infer, this hormone when it reaches your thyroid gland will STIMULATE your thyroid to produce thyroid hormones (thyroxine and tri-iodothyronine).





    To avoid overproduction/secretion of these thyroid hormones, these hormones will NEGATIVELY feedback on to the pituitary gland to stop production of TSH. This will then stop production of thyroid hormones to keep things in balance.

    Well, it's basically like a response. For example, if you get an allergic reaction, your body will release histamines in order to combat these foreign invaders.Explain how the hypothalamus-pituitary complex operates as a feedback control?
    This can generally be a hard concept with the fact the pituitary and the hypothalamus have many different jobs. But with a general reflex arc, or when the body is excited or scared for instance, there are a series of reactions that occur. For instance, if you were burned, first a message would be sent to the brain about the pain, and then the carotene and other materials would be sent through with your blood to make a temporary scar for healing purposes to happen.

    releasing factors are produced by the hypothalamus and these control or are referred to as trophic in lauralee sherwood because it causes the other organs to produce hormones in response......they nurture the pituitary gland........eg the hypothalamus produces CRH corticotrophin releasing hormones which stimulate the release of ACTH from the anterior pituitary gland.....ACTH will arrive at the target cells in the kidneys and attach to the receptors there and stimulate the kidneys to produce cortisol......an inportant component of combating stress......it helps to alleviate stress by causing an increase in glucose and amino acids to prepare for a stressful situation that requires fight or flight resp......together with adrenaline in synergism.......





    once cortisol is produced it will be circulated in the blood and will be transported to the hypothalamus and pituitary glands where their concentrations ';unbound'; to albumin provides the feedback control to determine the appropriate response.........this is a negative feedback control mechanism......as CRH levels decrease.....ACTH will subsequently decrease and therefore after cortisol reached its peak, the feedback control will turn off the production until needed again.........this is also known as the hypo-pituitary axis....and this axis can be altered due to many factors eg.....through the prolonged used of cortisone products like prednisolone......a cortisol derivative that suppresses the axis and when the medication is withdrawn....the axis will be affected....

    Why does natural selection favour negative feedback control over positive feedback control?

    negative feedback is the ability to maintain homeostasis and to be ability to regulate one's body/organism when impede by environmental conflict......the more able and organism can do that...the more fit they are and can contribute to the gene pool or reproduce and therefore natural selectedWhy does natural selection favour negative feedback control over positive feedback control?
    Good question.





    I would say that in general, positive feedback leads to unstability (going in a certain direction just perpetuates itself) while negative feedback leads to stability.





    Since living things need certain conditions to survive etc, the ones with feedback mechanisms that help maintain such conditions for long periods are a benefit. Thus, these individuals will survive better (i.e. natural selection ';favors'; them';). Think about hunger for example - if eating would make you more hungry again and again (positive feedback) - you would waste time searching for nutrients you don't need anymore. Your existing negative feedback, on the other hand, does a great job in getting you what you need.

    How does feedback mechanism help control body temperature?

    The feedback mechanism, also known as feedback inhibition, is a stimulator that halts/induces particular proteins/enzymes from doing their job.





    Example:


    If there is high levels of insulin in the blood, the brain would signal the pancreas to stop producing insulin.





    Likewise, when someone gets a fever, their body is fighting off the infection. Once the infection has been isolated/removed, the body decreases its energy (or focus) on the specific intruder. The brain signals for the WBC and T-Cells to stop attacking if nothing is remaining, and stops the production of WBC.


    That's why you don't always have a fever, after having a fever (if that made any sense)





    Let me know if that doesn't make sense.

    What is the function of a control center in a feedback control system for homoeostasis?

    A simple feedback loop to regulate a parameter is usually like this:








    ..(ignore the dots).d-|


    ..+............................\/


    r-o---%26gt;[c]----%26gt;[p]------%26gt;y


    - /\.......................|


    ....\____________|





    where o is the summing junction and the lower loop is the sensor loop which gives the error signal





    the c is the compensator, which boosts the weak input voltage and the p is the transfer function of the open system, (heater, lights, whatever is used to provide the change to the system), and y is the output (the homeostasis-ity if you will) d is an input that allows you to calibrate the system to perform correctly.


    The return loop(the arrow on the bottom pointing back towards the input) is a system sensor usually, and it reads where the system is actually at, so, if say the heat was low, it would read negative, which is subtracted from the input(thus adding) which would give a higher input voltage, causing your system to heat faster, then the closer it gets to the correct temperature, the value it reads that is off of what you want gets lower, and when it reaches the correct setting, it goes to zero.








    The short version is, you have a method of changing your temperature, your sensors read the current temperature, the control changes the temperature to this one.

  • Is thirst a positive or negative feedback control system and why?

    Negative. When thirst increases, it stimulates you to drink and so thirst then decreases. Thirst decreases itself in this way and so it is a negative feedback system.

    1.positive feedback is like acceleration..if there is an increase the reaction will be an increase like an increase in a certain hormone in ur body increases reabsorption of a certain material


    2.negative feedback is opposition a certain increase in the thyroxine levels in the blood will lead to a decrease in th thyroide activity while a decrease in the levels will trigger the tsh so thyroid produce more of the hormone....

    positive because its helping you
    it is not the matter of indicator,everybody thirst
    Thirst is a negative feedback in humans with Diabetes and some other diseases, means the body cannot regulate it's insulin. Thirst is a positive thing when a person is dehydrated, signaling a desperate need to replenish the body fluids so the blood can circulate and the kidneys can be cleansed.
    Both, it is positive because it replenishes what is lost in a normaly functioning body, it is negative if some function in the body is abnormal such as one sign of a form of diabetes is excessive thirst.

  • Can someone please explain to me how both negative and postive feedback control hormone release?

    and give an example of each.





    Thanks :-)Can someone please explain to me how both negative and postive feedback control hormone release?
    Any system, whether it is an open or closed, that regulates its internal environment to establish a stable and constant condition is said to be controlled by homeostasis. So the control of hormone levels is controlled by homeostasis, the levels are controlled in one of two way’s the first being controlling the release of the hormone and the second is by “mopping up” excess hormones.





    A positive feedback mechanism is designed to accelerate or enhance the output created by a stimulus that has already been activated. To achieve positive feedback a series of events initiates a cascading process that builds to increase the effect of the stimulus. This process can be beneficial but is rarely used by the body due to risks of the acceleration becoming uncontrollable. An example of positive feedback is the release of oxytocin to intensify the contractions that take place during childbirth.





    Negative feedback mechanism consists of reducing the output or activity of any organ or system back to its normal range of functioning. An example of negative feed back is the way mammals regulate their blood glucose with insulin and glucagon.





    Hope this is of some help.

    C. Decreases osteoclasts activity








    From http://en.wikipedia.org/wiki/Calcitonin





    CALCITONIN is a 32-amino acid polypeptide hormone produced by the parafollicular (also known as C) cells of the thyroid, which acts to reduce blood calcium (Ca2+) by antagonizing the effects of parathyroid hormone (PTH) in three ways:





    [1] Bones 鈥?Calcitonin decreases osteoclast activity in bones.





    [2] Kidney 鈥?Calcitonin decreases Ca2+ and phosphate reabsorption by the kidney tubules.





    [3] Intestine - Calcitonin decreases Ca2+ absorption by the intestines.Effects of calcitonin in the negitive feedback control of blood calcium?

    What would be a good project to do on Outputs and feedback and control?

    Such as which to chose: Powerpoint, Bulletin Board, Poster Board, Essay, or anything. Anyone got any good ideas???What would be a good project to do on Outputs and feedback and control?
    Matlab and Simulink if one has access to them.

    Where is a basic diagram showing negative feedback control?

    Negative Feedback Control Mechanism





    Factor effects body鈥檚 internal environment





    Increase / Decrease in factor





    Change is detected by receptors





    Receptors send out nerve or hormonal messages





    Messages received by effectors





    Effectors trigger counteractive response





    Internal environment returned to norm / setpoint.





    Hope this helps!Where is a basic diagram showing negative feedback control?
    what you need is the stimulus response model, for negative feedback, it is the same as for positive feedback only it loops back to the beginning.





    stimulus ----%26gt; receptor ----%26gt; CNS ----%26gt; effector ----%26gt; response (if negative) ----%26gt; stimulus and so on





    now for the parts of the model





    stimulus - change in internal or external environment,lets use heat, increase in body temperature





    receptor - receptor that picks up on the change,for heat its a thermoreceptor





    CNS - for heat its the hypothalamus, but for most models its simply the CNS (central nervous system)





    effector - the organ or cells that trigger the change in response to the stimulus, like release a hormone or contracting muscles, for an increase in heat, here are 3 examples


    1.thyroid


    2.blood vessels close to the skin


    3.hairs on body surface





    response - is the response caused from the effector, in order from the three above


    1. produce less thyroxin


    2. vasodilation


    3. lay down flat





    hope this answers your question!

    Would teh thirsy sensation when dehydrated be a negative or positive feedback control system?

    It would be a negative feedback control system, just like sweating. Negative feedback is when your body senses an unstable change in your body's internal environment and attempts to correct it. Your body senses that you need more water in your system so you feel thirst.Would teh thirsy sensation when dehydrated be a negative or positive feedback control system?
    When I read the question I'm thinking that it would be Positive, because you need water, and your body is saving your life. A negative feedback would be if you were not thirsty when you were dehydrated, so then you wouldn't know.
  • smokey eye
  • How do the hypothalamus and the pituitary glands control feedback loops?

    Through hormone levels and cell signaling. For example, when you're exercising on a hot day, and you overheat, your body recognizes the problem. It flattens your hair and you sweat, to reduce body temp. When your temp falls to normal, your brain recognizes that as well and terminates the action.

    Is it a positive or a negative feedback control system?

    when we become dehydrated, we usually fell thirsty which causes us to drink fluids. so which feedback is this?


    i think it's a positive feedback, if you think it's a negative, plz say why, thank you guys!Is it a positive or a negative feedback control system?
    Negative feedback loop! Basically, with feedback loops, you've gota receptor, a control center, and an effector. In your scenario of becoming dehydrated, let's say that you've been out in the sun for a long time and your body is losing water because of it. Your body knows how much water it should have and notices that it's getting kind of low. Your body detects the difference and, therefore, is the receptor in this case. The receptor (your body) will now send a signal to the control center (the brain) to let it know that the body needs water. The control center (brain) then sends an order to the effector to produce a response to the threat of being low on water. The effector does this by producing the feeling of thirst. Then you drink water and, after a short time, everything is normal again. A good example of a positive feedback loop is childbirth. Actually, most of the feedback loops in the body are negative feedback loops. Positive feedback loops, like labor and childbirth, just keep prodicing and increasing output from the control center (usually the brain, but not always) sending signals to the effector to keep producing responses without stopping. Think of a positive feedback loop as a thermostat. It gets hot in the room and the thermostat kicks on and begins to cool the room off. The temperature reaches a perfect degree, but it still keeps working and cooling the room off even more. Now it's really cold in there, but the thermostat keeps running cold. It eventually gets to the point where you need to break the thermostat or leave the room because it's so cold.Is it a positive or a negative feedback control system?
    thankyou sooooooooooooooooooooooooooooo鈥?much.

    Is the thirst sensation is an example of a negative or positive feedback control system?

    When we become dehydrated, we usually feel thirsty. Decide whether the thirst sensation is an example of a negative or positive feedback control system and defend your choice. (Either answer can be correct, if correctly defended)Is the thirst sensation is an example of a negative or positive feedback control system?
    why do you bother asking questions you already know the answer to? it takes all the satisfaction out of my answering the question.Is the thirst sensation is an example of a negative or positive feedback control system?
    Negative-you feel thirsty so you drink water and then you aren't thirsty. Drinking water doesn't make you feel more thirsty. As said in a different answer, labor contractions are positive-they make the contractions harder and more frequent-thirst make you act in a way to counter this.
    negative comes to my mind first and is logical. The only positive feedback I know is labor contractions.

    How does negative feedback control help maintain homeostasis in the endocrine system?

    Please give a SHORT, SIMPLE answer if you can please...!!How does negative feedback control help maintain homeostasis in the endocrine system?
    homeostasis have low self esteem so bad feedback makes them die off so they dont overpopulate endocrine system.


    thats how i like to look at it.

    How does negative feedback control work to terminate a homeostatic response?

    it works like a house heater:


    1. thermostat senses its too cold, so heater turns on


    2. thermostat senses its too hot, so heater turns off


    3. repeat 1


    4. repeat 2


    and so on
