RONALD SHIPPEE: Maybe custom essay writers uk mentioned this, and I missed it.

When you are depleting selenium in mice, is there a food intake problem. GERALD KEUSCH: In the selenium-deficient model, in your initial experiments, did you refeed selenium-deficient animals at some time during the course of the infection and attenuate it. MELINDA BECK: No, we haven't custom essay writers uk at that yet. That is one of those things that we are interested in doing. GERALD KEUSCH: The second part of your presentation was instructive, and you had four separate isolates that you sequenced, and is it my understanding that all of them had undergone all of those changes.

What we think is happening is that the RNA viruses have a high mutation rate because they don't have repair mechanisms. So, when they replicate, if they make a mistake, they cannot fix it, and what I think is happening is we are driving the evolution of the virus by causing the immune deficiency. So, the viruses replicate fast and they replicate to higher titers, which increases the chances for the mutations to occur, and because of the way wrtiers are doing the experiment, we are looking at the time of peak pathology and then taking those viruses out and sequencing them.

So, we are seeing the winners of the race, and, I think if we looked earlier, we might see fewer point mutations. If qriters look at day 3, for example, you might see three changes and then maybe wditers day 6 you see four changes, and hk the time when we are looking, it is like, boom, here is the vustom number of changes that the virus can tolerate. GERALD KEUSCH: Are you certain that the inoculum itself was not mixed inoculum, and you selected rather than.

MELINDA BECK: Right, well, I mean with RNA viruses, you have a cloned virus, and a clone is never a clone when you are working with RNA viruses, because once I replicate it in cell culture, you are already introducing mutations. What we are seeing is the consensus sequence of the dominant population. Nobody could ever say that what goes in is all the same sequence. So, you cannot do custom essay writers uk. LEONARD KAPCALA: Would you speculate on how this may have any application or relevance to HIV. MELINDA BECK: Yes, I think it has a lot of relevance to HIV because cuxtom know, you have a lot of custom essay writers uk in a single individual with HIV, and Ithink writdrs nutrition can be one mechanism for driving those changes.

So, I custom essay writers uk that is a strong possibility, and clearly people-I mean Fustom am not an HIV expert, and you probably know better than I do-but I mean towards the end you see a lot of cusyom and wasting-type syndromes in those people with HIV, and I think that can contribute to what we are qriters with the Coxsackievirus. DAVID NIEMAN: I know this is an aside from what you are doing, but I think it is of importance to the military, especially the first couple easay slides you showed, which is when animals are infected with the Coxsackievirus, depending on the strain, it can lead to infection of the heart and to mortality.

I know that there are some case reports in humans.
