Human Blood May Contain A Cure For AIDS 309
Lisandro writes "German scientists at the University of Ulm have identified a natural ingredient of human blood that prevents the HIV-1 virus from from infecting immune cells and multiplying. The molecule, which they call virus-inhibitory peptide (VIRIP), promises new types of effective treatment for HIV in the future. 'Tweaks to its amino acid components boosted its anti-HIV potency by two orders of magnitude. Tests also showed that some derivatives of the molecule are highly stable in human blood plasma, and non-toxic even at very high concentrations. A synthetic version of VIRIP also proved effective at blocking HIV, excluding the possibility that some other factor was responsible. VIRIP targets a sugar molecule which HIV uses to infect a host cell. '"

Think about it. You have a severe case of the common cold as a result of HIV suppressing your immune system. If you get rid of the HIV, your immune system is no longer being suppressed. Now that that's the case, your body is only fighting on one front instead of two, which gives you a chance to fight off the cold. You may need drugs and treatment to aid your body still, but you've got a fighting chance.
This is all just my opinion, based on my understanding of things, of course. I'm not a doctor or medical professional.

Imagine a wall with hundreds of doors on it, each with a different type of lock. Viruses are like burglars trying to break in, but they each only know how to pick one kind of lock. This type of treatment will result in blocking only the doors that have the same type of lock that HIV uses. Hepatitis, for example, would use a very different lock (different wall actually).
Or, since this is slashdot, you could also look at it as a host's firewall. HIV may attack a specific port, and this treatment may block only that port.
This is a very simplistic way of explaining it, but for the most part, this type of treatment only has an effect on HIV's specific attack characteristics. Viruses are usually very particular about what types of cells they attack, and then it can get even more specific. I'd view this as a specific fix.
Now, where things can start to get interesting is if they can manage to generalize this approach to find the appropriate blocking peptides for other types of viruses. If the approach can be generalized, then you might be able to find treatments for other viruses, but the hope for a universal cure for viruses isn't very feasible.
Viruses hijack our own internal machinery to reproduce themselves, so you can't exactly target them the same way that you can bacteria. (There are some common points that are being used to target specific classes of viruses, but I'm not aware of any universal point of attack). You can pretty much target viruses are three points: 1) at the point of infection into the host cell, 2) replication of the virus, 3) at the point where the daughter viruses leave the host cell. The approach mentioned in the article is of type 1.

In Africa it is a common belief that using a condom is "unmanly" and a woman, even a prostitute, that requests it is likely to get a beating. Condom use is a joke in Africa - it isn't going to happen.
What this means is you have infected people running around loose infecting more people constantly. Sure, there are millions of infected people. People that don't understand how the disease is transmitted and are constantly lied to about it. And people that are so completely caught up in the cultural prohibitions about things like condoms and birth control that it will never stop.
Spending money in Africa to control AIDS is like sending food aid to the warlords in Somalia.

Predators, like cats, cannot taste sweet because their body receives enough sugars from their food sources that they don't require the need to seek more out.

This has nothing to do with predator status, it's only cats, not the rest of them.
Cats both large and small harbor a genetic mutation that renders the sugar detectors on their taste buds inoperative.

"Ketone bodies, from the breakdown of fatty acids to acetyl groups, are also produced during this state, and are burned throughout the body. Excess ketone bodies are excreted in the breath and urine. The brain has a residual need for glucose because ketones can only provide energy when used during aerobic respiration in mitochondria. In the long thin neurons, much of the metabolically active cellular membrane must derive its energy from glucose via anaerobic respiration without the assistance of mitochondria."
Yes, that's right, parts of the brain are incapable of making use of ketones for energy (but who needs cellular membranes, right?).
Ever hear of ketosis? No, I don't mean the bull-shit "ketosis" that retards trying to push low-carb diets talk about, I'm talking about real ketosis, the time when your body ends up with a large overabundance of ketones and you end up "drunk" all day long. Then, after that, you end up in a ketone induced coma. Then you die.
The atkins diet has been changed three or four times because the original "Atkins" crap was pretty much globally recognized as being dangerous.
Yes, there are a lot of retards who say things like "A lot of people mistakenly think Ketoacidosis when they hear ketosis, but it's a completely different thing."
No it isn't you jerks, Ketoacidosis is just another name for Ketosis (interestingly ketosis was referred to as the danger condition by medical professionals 20-40 years ago, it changed to "a natural body process" with a different name for the condition around the time of these low-card diets).
"Ketosis occurs when there is not enough insulin in the body to metabolize glucose and provide energy to the cells of the body. The blood fluids become increasingly acidic until the starving body cells malfunction, causing staggering, slurred speech, disorientation and poor judgement. Eventually, the victim of ketosis may have seizures, go into a deep coma and die if untreated." http://www2.jsonline.com/alive/column/aug99/howar
http://en.wikipedia.org/wiki/Ketoacidosis [wikipedia.org]
See, here's the way it works. Ketones are emergency power for some cells in your body, i.e. if you are starving you'll have enough energy to go kill something, but that's about it.
Outside of that single use, ketones are a giant danger to your nervous system. If you don't drink large amounts of water to wash them out of your system you end up staggering around like a drunken hobo. Atkins guy, try laying off the water intake for a couple days then see how you feel. At that point, come back and tell us how well the brain runs on ketones.
The fact that you can function at all is due to the fact that you keep washing the toxin out of your body in your urine, if you didn't your blood would end up too acidic for you to live... and, well, you wouldn't any longer.
Ketones are better than glucose my ass...
