Effective Cancer Treatments Follow The Clock

...ice, the scientists found that the body's internal biological clock affects the survival of immune cells that are targets of the anti-cancer drug cyclophosphamide (CY). “We became interested in examining this issue because there is a long history of knowledge that chemotherapeutic agents produce different mort...

LUCA technologies confirms real-time methane generation

...ates that the methane formation is the result of a biological process occurring today. Luca is actively working to characterize Geobioreactors and the microbial consortia that populate them, as well as to understand the metabolic processes by which those consortia generate methane. The company expects to evalu...

Multiple Campylobacter Genomes Sequenced

...their presence could help to explain the different biological behaviors of these strains. There are also major variations in the genes responsible for synthesis of molecules that are important for the interaction of Campylobacter with the environment. Such differences could underlie the host specificity of the ...

Potential treatments for neurofibromatosis

...t cell itself," said Dr. Clapp. That's because the biological activities of non-malignant cells are stable, while malignant cells are constantly changing due to the genetic instability common to tumors. By using drugs that target the mast cells' ability to promote blood vessel growth, Clapp and his colleagues ...

Scientists discuss improved biopesticides for locust control in West Africa

...IRED), and Foster Agblevor, associate professor of biological systems engineering, traveled to Senegal to speak about their biopesticide research at the "International Scientific Seminar on Desert Locusts" held in Dakar in January. Biopesticides are types of pesticides derived from natural materials such as mi...

Variation in women's X chromosomes may explain differences among individuals, between sexes

...s," he continued. Notwithstanding the genomic and biological significance of these sex-specific differences, many questions remain, Willard said. For example, further study is required to determine if the pattern of X inactivation differs across tissues or over time and whether there are characteristic pattern...

Use of PET can reduce, may eliminate more strenuous drug development trials with animals

"Here we're showing an integrated package where the cells have an ability to send messages and other cells have the ability to act on these messages," said Weiss. T...

UCLA launches $20 million stem cell institute to investigate HIV, cancer and neurological disorders

...itute co-director, and a professor of medicine and biological chemistry. "I see cancer and stem cells as tightly linked," Gasson said. "More and more evidence suggests that cancer is a stem cell disease. Many of our current therapies are not effective because they don't target the cancer stem cells. Our experi...

HIV vaccine trial breaks ground for future research

... For the non-white group, the authors suggest that biological differences in immune response or genetic markers of resistance to infection could have made the vaccine more effective. Also examined in the trial were the immune responses to the vaccine. The vaccine was able to generate antibody responses in virt...
