Viruses can infect any cell: a virus must have a host cell (bacteria, plant or animal) in which to live and make more viruses. Outside of a host cell, viruses cannot function. Source This includes the dendritic cells: Dendritic cells are antigen-presenting cells of the immune system. Their main function is to process antigen material and present ...

You can fairly easily substitute peptides (short proteins) from the outside of the body, but you have to supply them by injection. They don't survive the low pH of the stomach unless you encapsulate them into an acid-resistant matrix. Short peptides are often very local and short acting, present only during specific times of the embryonic development (for ...

It sounds like you need a microscope for standard microbiology lab tests. At a minimum, any standard wide-field/brightfield microscope would work. If most of your histology work involves colorimetric stains (e.g., H&E, gram staining), you don't need any fluorescence capability. If you are working with a lower budget, look at the new lines of LED-based ...

I am colorblind, but I did not know that before I was 22 (!!). I got to know it by doing the Ishihara test. There are other tests you can do to test for colorblindness, such as the reverse colorblindness test (http://www.cs.unm.edu/~aaron/creative/colorTest.htm), where a "normal vision" person will not see the two patterns shown there. Anyway, there is no ...

Every infectous disease works this way: if you had contact with x particles (virus, bacteria, etc...), then you have y% chance to get infected (depends on your immune system, luck, etc...), so it has a distribution. This is called virulence, and it can be measured with ID50 (infectious dose by 50% of subjects) and LD50 (lethal dose by 50% of subjects) ...
