I have heard that cracking fingers or knuckles does not cause arthritis, but if you crack your fingers/knuckles very often, are there any other adverse health effects? Is there any way someone addicted to finger/knuckle cracking can stop it?

hey can any1 explain to me briefly what anabolic steroids do in relation to GnRH, i think something about them causing the GnRH to release more estrogens and testosterones and that they ignore the negative feedback mechanism in our body...but im not too sure...

Some people say that smelling coffee will wake you up and make you more alert. Is this true or do you actually have to drink the coffee so that the caffeine enters the bloodstream. If you're worried about too much caffeine in your sytem, would smelling coffee regularly be a good substitute for drinking coffee?

Hello, I am doing a research project on cell signaling in acute myeloid leukemia started by writing all about leukemia, then wrote general information about cell signalling and jak/stat normal pathway I was wondering if anyone know or can help in finiding information on what happens to this pathway in the presence of acute myeloid leukemia? i have written about ras, rtks flt3 and genetic translocations that happens in the presence of acute myeloid leukemia.But i still think that something is missing.can any one help please

Out on the golf course yesterday, I became an all you can eat buffet for the mosquitos in the area. (I actually caught one of them in the process of feeding off of me. It was kind of cool to see. I swatted it away and it left its snout stuck in my arm, and every time my heart beat the snout would twitch a bit). Anyway, when the mosquitos first bit it just itched a tiny bit but I left it alone and just put some rubbing alcohol on it. Today, however, the two bites that I have noticed have swelled up tremendously! It now looks like I have a golfball under my left forearm and my right wrist. I'm going to get it checked out after work, but since they are both quite red,…

For patients with immunodeficieny problems: Why can't we harvest bone marrow stem cells, culture them and mass produce them so they divide infinitely (weren't stem cells suppose to be able to?). Then introduce various extra-cellular factors that allows them to differentiate into T-Cells, B-Cells, neutrophils, basophils, etc. and then re-introduce them into those patients with immunodeficiency problems? The MHC would still work effectively if the bone marrow stem cells were obtained from the same patient. I can see that this wouldn't really work in leukemia, since it is already the proliferation of WBC's, however, wouldn't this approach work in a insulin-like manner b…

I don't know whether my seat-monitor alignment is incorrect but everytime I'm on the computer I have a habit of leaning forward without realizing it. I'm worried that too much forward leaning might arch my spine and give me a nerdy hunchback appearance. Is it natural to learn forward while sitting? Is it how I'm supposed to sit?

Sometimes when I take a glass from the pantry I pour myself some Coke and drink some only to realize that the glass was just recently washed. In the Coke I could taste some detergent residue. Is drinking of detergent in small amounts harmful?

I know that the best age for getting braces is around 10 to 14 years old but I heard that if you get your braces later than that age range, its possible for your teeth to revert back to what they were (in other words a waste of time adn money) before you wore your braces. so even though your teeth will be fixed in good positions when you wear your braces, maybe after a year or few years....your teeth will just revert back to the crooked positions they were before. Does any1 know if that is true?

Lately, my friends told me about a new LAN center in my area. We usually go about once a week to play games and have fun. Unfortunately, whenever I'm there for more than about 30 minutes, it becomes hard for me to focus and I get a headache. I've come up with several causes, but I'm not completely sure. - Its dark inside to give that cool sort of arcade feel. I was thinking that maybe its causing eye strain. -I'm wearing headphones, and thought that perhaps i was wearing them too tight, but removing them only helped my headache a tiny bit. -Its in the middle of the week, which means that I'm usually tired from school and work, and I was thinking that maybe tha…

is it possble to fuse skin to non-biological materials such as steel or plastic, sounds crazy but imagine like a patched quilt. Where the quilt is human skin and the patch is made of steel. Their is no skin underneath the steel patch. hard to explain...

What I hate most is perhaps people making money by fabricating ridiculous ailments, manufacturing ridiculous products is no where near as ethically wrong. Examples of these somewhat ridiculous ailments proclaimed by the medical society are ADD (attention deficit disorder), CFS (chronic fatigue syndrome), depression, and dyslexia. To the medical society the universe is perfect and so should every human being, anytime a little thing is wrong with more than one person they call it a condition. These guys, these pretentious professionals declaring such flabbergasting ailments do not realize they are perhaps the least competitive and productive of all professionals. Engineers,…

How does the Jendrassik maneuver work?

My mother wants me to go to the doctor, but I don't think so. I( woke up yesterday with a hurting thoat and a small caough, but it wasn't too bad so I went to school. But then today I had a really sore throat. I have a history of strep thoat, my little sister has been sick, and my auny (who we recently visited for the day) is sick and had to take anti-biotics. But it's been weirdly cold, so the heater is on and the air in the house is drier, so maybe it's just dry. And I have no fever, only a small caugh and a horribly sore thoat.

recently i came across this question in one of the scientific journals, that man can theoretically live up to a hundred years. it stated that man can, with the help of current technology and the vast leaps and bounds in medical science, along with progress in the genetics field. so i am here to conduct a poll whether man can live up over hundred years. if you do support it and agree, please state why. would appreciate if people who don't agree would also supply reasons. thanks........ maybe i should rephrase my question. with the advances in anti-ageing science, can we live beyond 100? if so, technically how is this possible?

Sry having a major brainfart but its when you use treated viruses to insert their only RNA into patients whose DNA has turn malignant in hopes of correcting the problem it has a pretty specific name... so any ideas?

Wondering if any of you might know whats up with me and my roommates eyes. In the past 3 weeks, we've both had very bloodshot eyes, Him twice. Its not pink eye. Theres no itching, no pain or any discomfort, Just extreme bloody eyes. Not really bloodshot, But what appears to be actual trauma to the eyes of blood pooling in the corners of blood. After a few days it clears up. Any ideas?

Hi, I am new to everything medicine and was hoping someone could tell me the field in which scientists actively research causes and cures of diseases ect Do you have to go to med school or do you study medical science at uni if you were interested in being a researcher? Where does the money go to when raised in say a fight cancer charity? Any info would be greatly appreciated. Thanks

Some senses are bad such as pain, some are good such as nice food. But at the end of the day, they're simply electrical impulses interpreted by the brain. Its a bit hard to get your head round but, why do we dislike pain? or like a nice taste?, there both 2 different sensations, however one we are taught to dislike, and one we are taught to like. Its not a very tangible idea, but why do we dislike pain? Im not talking about evolutionary advantage, or why we should want to im talking about what it is that the brain does, to make a sensation "bad" or "good", because they are both still sensations. Secondly, is it possible to change our perspectives, i know peopl…

I'm currently a student in the molecular bio faculty, but the topics that are introduced to us right now are pretty scarce, enzymology, proteomics, molecular physiology, etc. and none of them actually goes into great details to get me interested in a particular field... is it because molecular bio is a generalized name for all these categories and that I have to choose one of the streams after I graduate in order to continue studying under this field?

I heard that an excess uptake of vitamin C would contain some severe cancers, is it true? How many citrus fruits should I eat a day?

I`de like a little Advice with regards to Fever I have a temp of 104 nearly 39c with a chest and kidney infection, I`m on ANOTHER course of antibiotics now then, at this temp, is it best to maintain it, or is it best to try cool down? I know the temp is the bodies way of fighting the infection, so I`m currenty still wrapped up warm with a wooley hat on (no jokes please!).

I think this has to be placed on the Medical Science forum but I'm not so sure on where (probably Genetics) but I want to be sure. Like the title mentioned above, I have several questions. I'm doing a research on the human papilloma virus. I found that this is the cause of genital warts (or veneral warts) which occurs in humans (both men and woman). For men, it occurs near penis while for women, it occurs vaginal lips, inside the vagina, on the cervix, or around the anus. This disease is afffected, or more likely transmitted, through the sexual contact. Its effect is that it causes cervical lesions and increase risk of cervical cancer. Its genus is papillomavirus …

Hi everyone, I'm interested in finding out what people know about pharmacists' education, both undergraduate and postgraduate, and also what you think about pharmacists taking on new roles such as prescribing and medication reviews, and the increase in products being made available from pharmacies without prescription (such as simvastatin) I'd also be interested in your views on pharmacies selling products which have no evidence base, such as homeopathic products and copper bracelets. I can only add comments from a UK (possibly European) point of view. Cheers

I was just reading up about convection here: http://en.wikipedia.org/wiki/Convection and it said: "Convection occurs in atmospheres, oceans, and planetary mantles, and chicken soup." and I just found the random "chicken soup" was quite amusing, so I clicked on it and went here: http://en.wikipedia.org/wiki/Chicken_soup interestingly it said: although it does say that: just thought it was interesting.
