Summary: The article talks about an experiment that these authors did to see if the toxin, Anthrax, has similar effects in a Drosophila fruit fly as in humans. If the experiment proves to be successful, researches will be able to use fruit flies in experiments to better understand the effect of toxins in humans. Anthrax secretes three exotoxins, a lethal factor, edema factor, and a protective antigen. Each of these exotoxins may cleave or inhibit different genes in the development of the fruit fly.
According to the author, not very much is known about this topic right now. The article deals briefly with a few of these symbiotic relationships, explaining the chemical, ecological, and Ling200 hmwk 3 balance that must occur. It's not the most exciting topic or the easiest to understand upon reading, but I think the article does a good job with discussing the multiple layers of this biological interaction that occurs in many places in the ocean.
Livingston, and Amy M.
Buddie, Journal of Studies on Alcohol, volume 67, pg, September The studies conducted on women metioned in this arcticle were meant to isolate the effects on women's ablity to percieve sexual risk factors when intoxicated.
I believe our class would befenit from examining this study because, first and foremost, we are college students. We are no angels. By this, I mean to say that with us being the proclaimed "number one party school" a study on booze, sex, and women, might keep some of us awake, especially the girls in our class since we are the exmined specimens in the study.
It might also help the boys in our class to realize the part they play in the sexual assault game when drinking. Yabuta, H. Onda, M.

It is known that three conditions, serum starvation G0-scontact inhibition G0-cand terminal differentiation G0-t can induce eukaryotic cells to enter the quiescent state. I think that this article is extremely interesting because not only is it in correlation to what we have been recently learning about genes, but I think it is highly beneficial in cancer research.
Radwan, Laura, G. Toxicon, volume 45, pagesJanuary The objective of the research is to examine the toxic properties of a type of venom found in a jellyfish that is native to Puerto Rican coastline and the surrounding waters.
I find that it is relevant as a potential candidate to discuss in class because the researchers deal with interactions among living cells and foreign substances that could potentially harm the organism on the molecular level.
Seeing as how a large portion of our class is dedicated to studying organisms from their most minute components, this is, in essence, taking our studies of mollecular biology to another level.
Genes have a major role with obesity and mutations can cause other diseases related to obesity. The question "is genetic risk for obesity due to disease-producing common alleles?
I think this would be an interesting article to learn about because obesity is a rising problem in today's society. They're already a part of our immune system, but a part that, until now, we thought was the culprit for venom-related poisonings.
How do these mast cells work? Why did we think them harmful? What can be done with them that could aid in the treatment of venom poisonings? The world of anti-venom is certainly in need of a modernization. Right now we have to capture poisonous snakes etc. The researchers investigating black-capped chickadee calls did not closely follow the rules of strong inference.
They devised a hypothesis, then set out to prove it right.
They produced very thorough and convincing data, with thirteen different predators varying widely in size. However they failed to rule out other factors besides predator type and behavior whether stationary or moving that could affect the chickadees call. Templeton, Greene, and Davis claim the control experiment negates all the factors but the ones they are researching.
The article never explained how close the predators were. They should all be the same distance from the chickadees, otherwise it could be said distance plays a role in the chickadees call. I hypothesize that a closer, stationary predator would cause more alarm than a moving predator farther away.
There is no way of knowing this from the article, as they did not design the experiment to test distance. However there is no evidence in the article that they controlled the experiment to rule distance out as a factor. Several other things could have an influence on the chickadees call that the researches failed to rule out, including color variations among species, and time of day the experiments were carried out.Looking for CLC Pocket Polyester General Purpose Tool Tote, 11"H x 14"W x 11"D, Black (1LWK3)?

High-molecular-weight kininogen (HMWK or HK) is a circulating plasma protein which participates in the initiation of blood coagulation, and in the generation of the vasodilator bradykinin via the kallikrein-kinin system. HMWK is inactive until it either adheres to binding proteins beneath an endothelium disrupted by injury, thereby initiating.
