Researchers reveal the infectious impact of salmon farms on wild salmon

...ck up the sea lice, the migrating school becomes a moving cloud of contagions. Sea lice larvae mature and reproduce on the seaward salmon with each louse producing 300-800 eggs. This second round of lice larvae can re-infect the fish in the school and can spread to other previously unexposed populations com...

First-ever Compounds To Target Only Metastatic Cells Are Highly Effective Against Breast, Prostate, And Colon Cancers

...r. Huang said. Dr. HuangÕs next important step is moving these analogues into clinical trials. "We're trying right now to get a company interested in this, especially because the mice used in our trial seemed to experience minimal toxicity -- a good sign that patients might tolerate these compounds, too,"...

Scientists discover that host cell lipids facilitate bacterial movement

...se these lipids also localized to the front of the moving bacteria." The researchers also noticed that Listeria movement slowed down when the bacteria were treated with molecules that inhibited PI3-kinase, proving that Listeria depend on PI3-kinase to move. "Our studies show that Listeria is capable of ins...

New Treatment Rivals Chemotherapy For Lymphoma, Study Finds

...eatment worked as first-line therapy in our study, moving this treatment up earlier in the course of a patient's illness should be strongly considered instead of using it as a last resort or not at all. These results support the notion that there's a real possibility of putting chemotherapy on the back burn...

Protein offers way to stop microscopic parasites in their tracks

...the addition of chains. The parasite supplies its moving belt with traction by putting spots of an adhesive protein on it. The adhesive protein allows the host to attach to the exterior of the host cell. The resulting contact points give the belt something to push against as it moves backward, in turn push...

Molecular Motors Cooperate In Moving Cellular Cargo, Study Shows

...n carry the peroxisomes in a step-by-step fashion, moving about 8 nanometers per step," said Selvin, who also is a researcher at the Frederick Seitz Materials Research Laboratory on the Illinois campus. "Because we see a fairly constant step size, we don't believe a tug of war is occurring," Selvin said. "...
