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…

I have an idea medical search, I want Research Center performs this search and i give him financial compensation . Is there such a thing?

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. The quote in the title came from the New York Times by the way, if you don't feel like ploughing through the paper the article is here: http://www.nytimes.com/2014/02/12/health/study-adds-new-doubts-about-value-of-mammograms.html?hp&_r=1

Hello everyone Here are some questions I have about spinal anaesthesia 1. I know it is usually done below L3 because that is where spinal cord ends and not done above that because spinal cord can get damaged. But can't a really skilled person give it above L3, because subarachnoid space ends before spinal cord? So if he stops at the right time wouldn't it work giving anaesthesia from a higher level. 2. Why does the spinal anaesthetic agent only act below the point it was administered. Can't it diffuse up and affect the whole spinal cord? 3. Why can you achieve higher level anaestheisa (Meaning from chest to toe) from epidural anaesthesia? 4. What is t…

Hi Guys, I wasn't sure where to put this question - here or in the religion, sorry. Full disclosure, I'm a big fan of Sam Harris and Christopher Hitchens, basically I'm very concerned about how religion is affecting the world. So here's the question: Given that religious discussion must be predicated on dogma, and that scientific discussion must be predicated on a lack of dogma, do people who are both religious and scientifically minded experience a sustained, cognitive load burden in day to day life as they switch back and forth from religious situations to "scientific" situations? (In this context, we could call jobs like programmer or sys. admin…

Hello everyone. As I was in the grocery store today, I noticed a thinner couple encouraging their young (probably around 10) to go and get a free chocolate cookie from the deli. A few hours later, while talking to my friend, we got to talking about child obesity. He does not contest that diet plays a large role, but he also believes that genetics are the root problem. This led me to question my stance that an overweight child is only truly overweight because of the parents influence or lack thereof on diet. I am not asking for opinions on child obesity but rather, do any of you have examples of genetics being the reason for an overweight child rather than diet? Pl…

Hello everyone I still don't understand crystalloids 1) Lets say someone lost 100 ml of blood due to accident. If you are giving crystalloid therapy, why do you have to infuse 3 times the amount. What I think is when you give crystalloids IV, they go into extravascular and intravascular compartments also, not just stay in plasma . But my question is let's say I give 100 ml of crystalloid to this person, then wouldn't the patients body try to retain this 100 ml in plasma because now the hydrostatic pressures have changed due to the blood loss, shouldn't the body compensate and try to keep this in plasma. In that case why should you infuse 3 times the amount. In normal …

Does pouring salt on a wound actually kill bacteria? say, a cracked tooth.

Thought this article was really interesting, and might just change your mind on why it is that we 'need' sleep. http://www.tor.com/blogs/2013/07/scientific-american-explores-a-new-hypothesis-on-the-fundamental-purpose-of-sleep

Hello guys, Ok lets say there is a man with fluid in his lungs. You put a chest drain (intercostal tube). How does it drain? 1. Since the container is below the chest, when the guy expirates due to high pressure does fluid just flow to container? Can there be any retrograde flow (since container is below on the floor does gravity prevent this) 2. The article I read says with intercostal tubes, look at the water level of the container. In inspiration it must rise, and it must fall in expiration. If this doesn't happen tube is not working. What water are they talking about and also why does this phenomenon happen. Thanks :smile:
