The alcohol-based gels, widely available in stores, do not require water and rapidly kill most bacteria and viruses on the skin. They are a convenient alternative for busy parents who are unable to get to a sink while caring...

Anti-HIV drug has potential to prevent transmission in women

... safety trials of microbicides showed that certain gels caused ulcerations and inflammation in women that could actually facilitate HIV transmission. The favorable findings of the tenofovir gel's Phase I safety and acceptability trial has already led to a larger Phase II safety study in at-risk women due ...

Manchester scientists create new bio-gel for 3D cell culture

...he gel. They found that both the properties of the gels formed and the cell response to the gels could be controlled by using different combinations of di-peptides. The team recently received a £6...

Unique soybean lines hold promise for producing allergy-free soybeans

...nd screening using stronger antibodies and protein gels was done to confirm the absence of P34 in the two domestic lines, Joseph said. After the two lines were isolated, seeds were sent to the Danforth Center for additional molecular analysis to determine why P34 was absent. Six identical genetic mutatio...

Professor Rothbergs concludes, "This could be very important for applications in personalized medicine where a particular DNA sequence will be linked to a prescribed therapy. In fact, we see this happen...

Growing nerve cells in 3-D dramatically affects gene expression

...'t grow that way. They are suspended in fluids and gels and surrounded by other cells. And these cells aren't stuck; they move. As a result, some scientists suspect that hothouse cells do not behave like in vivo varieties. This means that the critical functions scientists are trying to understand by st...
