Medical Science

I once heard something about this in a documentary on TV, and it's an idea I find fascinating and amazing even if slightly creepy too. Today's technology allows advanced biological manipulation and medical procedures to be possible... even things such as cloning to some extent. But what about creating and growing functional organs and body parts from scratch? Or, an even more daring question, creating complete forms of life in the lab other than just simple bacteria? By "from scratch" I mean creating an organ or body using man-made devices and primary matter only... maybe with existing biological parts (like ADN) involved. For instance, I've heard about medicine being…

Hello everybody. I have seen many people asking questions on this forum about the reason to why blood pressure drops as you get farther from the heart. But honestly, not a single answer satisfied me. My major is physiology, so it's quite funny that I still don't know this "trivial" detail. What is the physics behind the drop in blood pressure? Because I was not satisfied with any of the answers, such as, - Capillaries have smaller diameters (because diameter shouldn't make a difference locally: decreasing arteriolar diameter increases mean arterial pressure, not arteriolar pressure, because the blood in the arteries faces higher resistance ahead of it so the a…

Hello everyone, I don't understand sepsis. Ok I know Sepsis is SIRS (Systemic inflammatory response syndrome) to an infection. But I'm confused with these scenarios. 1) Lets say I have a UTI in kidney. The immune system localises the infection to kidney and causes massive inflammation in that area and fights the disease, with out allowing it to spread to otherarea. Now is this Sepsis? If it is not what do you call it? Here also inflammation towards infection occurs so why is it not called sepsis? Does CRP increase in this scenario? 2) Lets say I have a UTI in kidney. It spreads to all areas in body. Massive systemic inflammation occurs towards the infection. I'm assum…

I've always been told to wear socks when walking around the house bare-foot because I'm going to get sick - even when I'm standing on carpeted area. I've always walked around the house bare-foot, and even outside sometimes and never had any problems with it, yet I'm still told it's not a good idea. Is there any evidence to prove this idea that cold feet will cause you to get sick? From my personal experience this has never been the case.

New pain medicines are apparently being derived from frogs.

I wanted to start a discussion about complex diseases (atherosclerosis, asthma, multiple sclerosis, etc.) and why we have had a difficult time figuring them out. Is it because we are searching for that one cause (either gene or exposure) that we hope can explain the prevalence of the disorder, like cystic fibrosis. Or is it because we group people with similar symptoms under there syndromes but in fact their diseases have different etiologies and are not the same disorder. I do research on the genetics of asthma and the field is shifting towards better phenotyping of patients to better understand how different asthmas come to be. There is a general belief that large …

soybean milk cant the real milk but is so cheap and rich in nutrients less fat and very easy to home made but i read it will increase Estrogen level in Men. how far is it harm to to men what is the daily recommended amount to drink for men

some where on this site (I can't remember where) there was a post on allergies being connected to immunization. Can someone help me find that post or give me more info on the topic.

I'm having my small intestine biopsied soon and thinking about it got me curious about whether the small chunk they will be taking out will regenerate? I seem to recall reading that all kinds of human tissue regenerate, is that true? Obviously if someone gets a large enough cut they need stitches for it to heal, if they have their arm amputated another one won't grow, but does the statement that all types of tissue regenerate hold true when it comes to tiny nicks like biopsy type nicks?

I've decided, for my own curiosity, to find out what happens to the human body when a person tries to use energy supplements as a substitute for sleep. I will be performing the experiment on myself, over the course of at least 57 hours (From 4:00 AM May 19 to 12:00 AM May 21). I'm aware that this isn't the safest -- or wisest -- of things to be trying on my own, especially given I've no experience or education in the medical field. I'm not here to ask your opinion on the safety of this, I'm instead here to ask what information I ought to be recording and at what intervals. My current log looks like this: Subject is caucasian, seventeen years of age, and in…

The ways I know of so far are below, does anybody know of any other possible ways? Remember that the consciousness has to stay going at all times, it does when you sleep by the way, and has to actually move through something and to the new and actually leave the brain if moving to a computer for example. 1. Nanobots to keep adding new brain cells and other cells. Or turn the brain cells and other cells into fixedup immortal cells. Or have them create immortal brain cells and other cells and add them and take away the old ones. 2. Create a computer with many firing signal shooters ect. to transfer consciousness to, or also partially a brain made of stem cells turne…

I have an assay that measures total heme in plasma... see: http://www.genoprice.com/DATA%20SHEET/DATA%20SHEET%20open%20bio/Bioasays/QuantiChr13.pdf Does this mean that the heme concentration measured includes the prosthetic heme groups attached to hemoglobin in addition to free heme? Thanks for your help!

what is the etymology of drug name moxidectin?

The medical progress is coming to brick wall. The medical progress is slowing down and yes medical breakthroughs is slowing down .Yes the public does expects medical breakthroughs to occur all the time and medical progress but it is slowing down very fast.One can just look at cancer,autoimmune diseases and organ failure. The problem with medicine is there is two approaches to problem drugs or surgery.And for the past 100 years drugs ware flying out like flies but are slowing down now and there is nothing surgery can do for cancer,autoimmune diseases and organ failure. When it comes to electronics that stop working or going bad we pop out the bad part an…

I have discovered that high frequency vibrations affect the nerves and sends calmness signals to the brain, so when a person is in my new invention, which is the vibrating bed, he feels very calm after a while, I designed the vibrating bed or chair with high but weak frequencies, I had a patent for my invention. will any company buy my new invention?

Hello everyone For as long as I can remember (i.e. for ages...) I've experienced a most awkward phenomenon - a feeling. First of all, please mind that it doesn't concern a psychological feeling like 'luck' etc. When an object, as far as I know mostly a metal (or conducting?) object, is brought close to (but not touching!) the spot (place) on my forehead, between and above my eyes, I experience a strange feeling; it's not painful, not as if something is really touching my head, it's more some kind of 'ticklish', but it's extremely hard to describe. It's not something experienced by 'seeing' an object this close, because it also occurs when my eyes are closed. …

How would one revive someone who was choked/strangled to death in a chokehold? Is manual CPR effective, when no help is available? Also, what are the consequences to the body/brain of having died/been revived from this, as opposed to, say, from a heart attack. Thanks. -D

Hello, I am assigned to write an Extended Essay for the International Baccalaureate Diploma Programme and I am looking to base my topic off of the history of either gluten sensitivity or Celiac's Disease. I am looking to argue that the consumption of gluten itself does not cause gluten sensitivity or Celiac's Disease (some argue that the genetic modification of gluten causes it) and that the rise in gluten sensitivity and Celiac's is similar to that of the rise of other allergies (i,e, peanuts, certain dyes, etc.). I am asking currently what your thoughts may be about this and if it is at all possible that you know any journals, books, etc that could help me in my researc…

Some antipsychotic medications are administered at intervals up to a month apart as a depot injection with the drug usually suspended in oil, usually vegetable oil such as sesame seed. I am curious as to why other drugs that are administered orally and slowly release over 12 or 24 hours, such as morphine sulphate contin and hydromorphone in Jurnista , have not been developed into a depot injection or an implant similar to contraceptive implants. I kind of understand the implications with drugs such as the above not being available as an implant because some people would dig the implant out to access more of the drug or sell it. It has long evaded me as to why these drugs …

Hello everyone, 1) Now in this catheter, how does passing saline through the ballon port inflate the ballon. Are there pores at the end of the tube, which allows fluid to go into the balloon and inflate it. 1) What is the purpose of a 3 way catheter. If you want to clear out an infection I can understand you can send saline through one of the ports, but can't we do the same thing with a 2 way catheter. If we send saline through the ballon port in a 2 way catheter, wouldn't it fill the bladder after inflating the ballon and clear it. 2) Why does a 3 way catheter have 2 ballons as shown in pic. Thanks

http://www.bmj.com/content/348/bmj.g366 What are peoples thoughts? Looks like a pretty solid paper, and a fairly damming conclusion to me.
