Study revises dynamin's role in nerve cell function

..., dynamin 1 goes into action only when the synapse enters moments of especially high activity. "In that sense, dynamin 1 remains crucial, allowing the synapse the freedom to function under all conditions," explains co-senior author Dr. Timothy Ryan, professor of biochemistry at Weill Cornell Medical Colle...

By looking at soil organic matter entering the lake using a specific compound derived from soil thriving bacteria the team could then compare the specific compound from the soil bacteria present in the lake sediments at different times to c...

Lack of sun does not explain low vitamin D in elderly who are overweight

...nd from supplements. When this fat-soluble vitamin enters the body it is converted in the liver to 25-hydroxyvitamin D. This is one of several important forms of vitamin D, and is the form that researchers and clinicians use as an indicator of vitamin D status in individuals. Vitamin D is especially critica...

Thus, a series of very similar growth factors ensure that the tubes branch out appropriately and achieve the right diameter. Another factor shared by t...

Researchers pit novel version of common virus against cancer

...tion of dNTP, such as cancer cells. Once the virus enters the cancer cell, it should also create new soldiers to destroy neighboring cancer cells while leaving normal cells alone, Kim said. When the job is done, the adenovirus should die out. Side effects should be minimal. Since the adenovirus does not c...

University of Arizona launches major scientific research initiative at Biosphere 2

A large and sophisticated array of sensors deployed throughout the chamber's atmosphere and the hill slopes will monitor environmental factors, including water, carbon dioxide, temperature, trace gases and pH...

Support for chromosomal theory of cancer found in cancers' development of drug resistance

...nactivate or damage the doors through which a drug enters a cell. Duesberg counters that aneuploidy is simpler and can explain the common development of resistance to many unrelated drugs within the same cancer. He has shown in experiments that aneuploidy causes many gene disruptions such as breakage or t...

UCF professor finds bacterial pathogen may be key to understanding cancer development

...ause of food poisoning. He has long studied how it enters into cells of the human body, and explains the mechanism in this months issue of the journal Cellular Microbiology. We found that Listeria actually provokes human epithelial cells (cells lining the small intestine) into ingesting bacteria, Ireton ...

Biocontrol of invasive water hyacinth contributes to socioeconomic and health improvements in Africa

Wind and wave action can accelerate the destruction of the weed started by the insects. No herbicide spraying was used in the Ugandan program, only mechanical removal ...

Fruit fly research may 'clean up' conventional impressions of biology

The concentration decreases with distance and forms the first blueprint that defines which part of the embryo will become the head and which...

Genomic analysis uncovers new targets for HIV vaccine

...nown as HLA-A and B, are turned off by HIV when it enters the body, which keeps the immune system from recognizing the virus as foreign. HLA-C however is not thought to be turned off by HIV-1. The new results suggest that for some individuals at least HLA-C is involved in controlling HIV-1. Since HIV-1 a...

Often, small openings at the bottom of the newly formed channel will allow the blood to flow out. But if the openings arent large, blood flow inside the fa...

Carnegie Mellon scientists find key HIV protein makes cell membranes bend more easily

Phase II study of therapeutic vaccine shows efficacy in patients with metastatic colorectal cancer

...any tumors. The idea is that the modified virus enters cells, produces the tumor protein and stimulates the immune system, said lead study author Richard Harrop, Ph.D., vice president of clinical immunology at Oxford BioMedica. To give a vaccine alongside chemotherapy might seem counterintuitive, since c...
