Frog peptides block HIV in lab study
...oring dendritic cells with antimicrobial peptides, washed the peptides away, and added T cells. "Normally the dendritic cell passes the virus to the T cell, and we get very efficient infection of the T cell," Unutmaz said.

...ing this process, half of the bacterial cakes were washed with water with four different ratios of oxygen-18 to oxygen-16. The washing process allowed researchers to calculate how much of the water extracted from the bacterial cakes came from outside and from inside the bacteria.

...y than previously believed that is available to be washed out of the atmosphere, even far away from industrial sources, Swartzendruber said.

Step one in any staining process is to soak a tissue sample in an aqueous solution of formaldehyde, called formalin.
