UCLA cancer researchers shake loose hidden biomarker

... researcher and senior author of the article. The method discovered by the research team places the prostate-specific membrane antigen (PSMA) in a location on the cell that would allow blood-borne immunotherapies to access the biomarker, transforming it from a hidden target into an exposed one. "In prosta...

Study of energy and health in Africa focuses spotlight on charcoal and forest management

... than wood, but the current inefficient production method in Africa is one of the most polluting for the global environment and potentially destructive to African forests. The researchers' analysis shows that charcoal can provide comparable health benefits of 1 to 2.8 million avoided deaths. However, scenar...

Genome study of beneficial microbe may help boost plant health

...ant pathogens is called "biological control." That method is gaining momentum as a way to grow healthy plants without using synthetic fungicides. In all, about three dozen beneficial microbes are currently used as an environmentally-friendly way to fight plant diseases. Joyce E. Loper, senior author of the...

Recombinant DNA technology may enable oral, rather than injectable, delivery of protein drugs

...rrin and half G-CSF," says Shen. "We refer to this method as recombinant fusion protein technology." Recombinant DNA technology utilizes a series of procedures to join (recombine) segments of two or more different DNA molecules. When put into cell culture, a recombinant DNA molecule multiplies itself to fo...

Novel live reporting system to track cells
