When we have just become infected with the common cold why does our mucous change in colour and texture. The colour changes from a more transparent clear colour to a thicker yellow-green colour. Why is this? And how does this happen? Anyone know?

How is this new drug made? Can you mix together this two active substances?

What is deaccylated trna? They say in the book that free tail cca is one A site of ribosome while the other nuvlotide end is on p site? I ont understand what they mean some picture or good video about it? This is written in biochemistry Harper 29 edt.

We all know we day dream ourselves to sleep at night visualizing scenes. For example, if you drive all day, at night, you will still see road ahead. I find the same thing happens with cards. In my case, if I play ten games of Freecell in the afternoon, it will take seven hours before I can go to bed that night, close my eyes, and not see the game in front of me; I can even play the game---somewhat. It is not vivid enough to be sure of any single card and when I am looking for the best place to put it, it is apt to change so that when I put it down, it no longer goes there! Rather than fight that, I stop playing Freecell seven hours before bedtime. Anyone els…

Comas are still somewhat a mystery in the medical field. Our brains go through trauma and we cant wake up sometimes for weeks even years sometimes. Is it possible that a coma is self-induced and a way for the brain to conserve all of the body's energy into healing the damaged brain? Think of it this way, you exert a lot of energy moving around and with your brain processing information right? So when your brain gets damaged it tries to make the amount of energy you wouldn't use healing your brain minimal. I'm just an 18 year old high-school dropout, no need to get mad if I'm wrong. Just throwing something out their to think about.

Hi all, My question is this: Can we ever hope to fully understand the brain when the most powerful tool in our possesion is the brain itself? Also, much of the brain is inaccessable to us consciously. Can a system (such as the brain) be "pointed" at itself? I'm struggling to phrase this correctly... but you guys are intelligent enough to get my gist.

Hi: I'm currently thinking of a substance that has similar medical effects as caffeine [such as increased sense of energy and the decreased perception of exercise-induced pain]. However, this hypothetical drug does not have any significant or direct effects on the urinary system, sweat glands, digestive system, respiratory system, or circulatory system. What actually-existing substance most closely fits the categories I'm looking for? Thanks, GX

I recently got into a pretty big debate with somebody on YouTube after I watched an episode of 'I Shouldn't Be Alive', in which a father and his 12-year-old daughter had gone camping in the Australian desert and their car broke down out in the middle of nowhere. I had demonstrated my incredulity that they had both left the house wearing jeans and sweatshirts (or some other long-sleeve clothing) even though it was something like 45 degrees Celsius out. I understand that it would help to protect you from the sun, but I know from experience, having been in similar temperatures while on vacation in Cuba, where I was often in nothing but a bathing suit and no shirt, and sunblo…

What is the technical term for looking for information that supports your theory only and ignoring contradictory information? Can anyone give me more information on the subject?

Hi: Here is my opinion about the use of cocaine HCl [a deadly toxin] vs. that of coca liquid [obtained by pureeing fresh green coca leaves into as fine of a paste as possible and then adding a sufficient amount of "drinking" water to this paste to dilute it into a bright green liquid]. No one could ever pay me enough to take cocaine HCl. This is a nasty monster than spikes your blood pressure to the point where your nose sprays out a fountain of blood. If you do survive and stop cocaine-HCl, you will likely up with a crash of dysphoria that will force you to end your own life. Avoid at all costs. Coca-liquid, on the other hand, contains a mix of different comp…

Are "psychopathic brains" organically driven, or does it have more to do with neural activity and blood flow?

"Intervention" might have been a strong word. I can't edit the title anymore. I'd like to know about studies or experiments concerned with maintenance of the brain into old age. I'll pass them on to the person when I have conversations with them. That won't seem like I'm forcing anything on them. I read about the SMILE I study where aerobic activity in the elderly both reduced depression and improved cognitive functioning, and I read about the rat study that showed running generated more Hippocampus cells and improved memory.

Most of common relationship problems people think between two genders are that they come from distinct planets. The way males fall in love is with their eyes, and the way females fall in love is with their ears. Male maybe can't understand in his whole life why so many women are full of vanity and comparing with other women. Women also feel inconceivable why men are so addicted to…

Maternal stemcell Maternal stem cell (MSC) is thefirst embryo stem cell. Maternal stem cell is located behind the 8ththoracic vertebra in the gray substance of the spinal cord, next to the spinalmarrow channel. Two axons go from MSC by the spinal cord to the cerebellum, penetrate into thalamus, hypothalamus, then one axon goes to the left and another one to the right hemisphere of the brain In the area of the frontal part of the brain, axons go down along the lower borders of the brain to the trunk of the brain. Moving by the trunk of the brain, axons enter thymus. Getting out from the thymus axons head…

"BIOLOGICAL CLOCK"CELL AND ITS ROLE IN AGEING AND ONCOLOGY Biological cell clock (BCC) are located in the DNA ofeach human cell. BCC is located in the DNA basis. BCC has a membrane, internal genetic material in the form of one long DNAchain, located as a ring along the membrane diameter. Nucleotide bonds arefound in the places of the DNA strands crossings. Besides A,T,G,C other nitrogenous bases are available. BCC reveals certain order of its construction from different proteins. BCC cellis divided into 2 parts by the membrane - the upper one and the lower one. The lower part of BCC consists of a dense liquid containing a double proteinstrand. Two pr…

New immune cell. These cells originate in the thymus of the differentiated stem cells. These cells are complementary to cellular and humoral immunity. The actions of these cells differs from that of T-cell immune system. The cell size is less than macrophage, outwardly looks like a clamp on the endsof which are concave inward staples mikrotubuly which at the moment effects on pathogenic cells injected into a toxic protein (lymphokine). This cell starts to assume all occurring on the way cells and organisms. Definition of a stranger by the rays of the wave inside the cell, which divide the space inside the cell into many small parts (a light beam lightblue). …

What are target drugs or gene therapy that doctors are working in the future use for cancer and other diseases? I hear talk of hope in the future that target drugs or gene therapy may be used for cancer and other diseases

I've heard in a lot of my classes that HIV is nearly impossible to make a vaccine for because of how rapidly it mutates (among other reasons), but I've been wondering something for a while. It's my understanding that HIV can only infect macrophages and T-lymphocytes, more specifically CD4+ T-helper cells. And I've also heard that HIV is also uncurable because there is always a small percentage of the virus that remains dormant inside its host cell, making it unaffected by antiviral drugs. That got me thinking though, because I've also heard that HIV is a very weak and labile virus when outside a host cell. So would it be possible to cure an HIV infection by literally …

Hi I've got a cure for jaundice.It worked on one person.It is ayurvedic and has no side effects. But i've to test whether it really works.And i don't know the procedures. Can anyone please explain how to do the test ? Thnx in advance. im 14 yrs old

We can currently do transplants of lungs, kidneys, livers, etc. if those organs are damaged or diseased. Will we ever be able to do so with brains? I've heard a lot about the possibility of growing replacement organs in vitro or using 3-D printers to create replacement organs. When will we be able to do so with brains? What obstacles lie in the way?

Efforts to ameliorate or cure type 1 diabetes by transplanting either the entire pancreas or the functional units of the pancreas, the beta cell islets, have had little success due to their destruction either by normal immunity or by the same autoimmune response in the patient which caused diabetes in the first place. Also, with about 800,000 type 1 diabetics in the U.S. and only about 5000 cadavers becoming available for organ harvesting each year, the donor supply could never make any difference in the disease epidemiologically. A major alternative to this approach has been to transplant animal pancreas islets encasuled in a differentially permeable membrane which …

I found this link quite by accident and thought it might be good information for just about anyone. Just don't take it as more than a grain of salt until you have researched it fully. http://www.cbn.com/media/player/index.aspx?s=/mp4/LJO190v1_WS

Obviously a lot of people are disgusted or titillated by the idea of drinking blood, but it seems like almost no one actually does it. The moral and practical barriers to drinking human blood are obvious, but animal blood is plentiful enough and probably plenty wasted. Do we avoid it just because of culturally taboo or are there medical reasons to avoid it? Presumably it would at least be a great source of iron. I've heard meat has hemoglobin in it, so we probably do ingest some blood, but why not drink it? In the Old Testament, blood drinking is explicity forbidden, which presumably means some people did drink it back then.

so first off i know this is weird but i would like to have an ampule or vial with my a small amount of my blood in it. past attempt's have failed since the blood coagulates and separates. i do not need "preserve" the blood so to speak since i will never inject it back in. my question: is there a household chemical or easy to get chem that will keep the blood stable (how it looks when it comes out) i know it is dangerous but i did lots of research and talked to a fe healthcare professionals about ho to extract the blood as safely as possible. thankfully i have good veins so even if said chem will ruin the blood all i care about is that it stays the same c…

do they or can they use just NSAIDs, acetaminophen or aspirin for minor surgery like for muscle biopsy?
