Efforts are being made to prepare the furry recruits for their futurelives in Betampona by putting them through a kind of lemur "boot camp."For instance, while the Duke animals now descend to eat "unnatural"rations of monkey chow, their keepers are varying their feeding sites. That'sto discourage depen...

Screening In Women Army Recruits Shows High Chlamydia Infection Rates

...t Prevalence Nearly one in 10 female new recruits in the Army is infected withChlamydia trachomatis, according to a study reported in today's New EnglandJournal of Medicine.

Could A 'Vaccine' Made From Our Own Cells Work Against HIV?

...ination is badly needed, as a recent study of army recruits has suggestedthat rates of chlamydial infection among young women in the US are as high as 10per cent (This Week, 12 September, p 5). A human version would rely on culturingdendritic cells from blood samples, rather than bone marrow (see Diagram). No...

EMAP II: A Cytokine Regulated By Apoptosis

...lease following apoptosis suggests that EMAP II recruits macrophages to sites of apoptosis. So far, no other mechanism has been described which can explain the accumulaion of macrophages at sites of cell death during embryonic development. Taken together, these results imply that the coordin...

'Dual Control' Strategy Assures Accurate Cellular Marching Orders, But A Pathogenic Microbe Can Hijack The System

Scientists discover key molecule in transmission of AIDS virus

... is presented, T-cells go into action, marshalling recruits to battle a foreign foe with special messenger molecules called cytokines and chemokines. Previously, Dr. Littman and colleagues discovered that HIV must bind to chemokine receptors on the surface of T-cells in order to enter the cell. Now, with the ...

Matrisian named Vanderbilt's first chair of cancer biology

...ing areas of cancer research. Many of these new recruits -- though certainly not all -- will be researchers in the area of cell biology/cancer biology, said Moses, who served as chair of Cell Biology from 1985-98. However, as departments grow in size, the ability of chairs to lead and mentor faculty can be...

Bio-X awards $3 million in grants for imaginative interdisciplinary research and education projects

...Levy lab have learned how to design a vaccine that recruits the victim`s own immune system," Swartz points out. "The challenge," he notes, "is that each patient needs a new and different vaccine. With conventional technology that new vaccine may take months to produce." But using a technique called cell-free ...

This is roughly the job description Keith Cooksey, professor of microbiology at Montana State University-Bozeman, carries with him as sear...

Immune cells SLAP internal signals together

...AP-130 protein works as an adapter molecule, which recruits other molecules to various parts of the cell. In this case, SLAP-130 has a role in adapting the integrin molecules in clusters outside of the cell. Those integrin clusters serve to secure the immune cell to its target, which can then be destroyed to...

Ten or more students will work in his lab at a time, learning everything from DNA sequencing to bioinformatics. Collaborators on the project...

Researchers discover new mechanism that targets and destroys abnormal RNA

...ognizes these ribosomes holding nonstop mRNAs, and recruits the exosome to degrade the defective messages, said Parker. The scientists experiments in yeast revealed that exosomes are, indeed, required for nonstop decay and that Ski7p does bind to exosomes. Their studies also showed that when Ski7p is mutated ...

UF researchers discover blood stem cells
