Biodiversity hotspots identify conservation priorities

...a encompassing Mexico's main mountain chains, some isolated mountaintops in Baja California, and a few scattered patches in the southern United States (represented by the Madrean Sky Islands, a series of about 40 mountain-tops in southern Arizona and New Mexico, and other mountaintops in Texas, including part...

No relief for Pacific Northwest drought

...stern Oregon and southeastern Washington, and more isolated but severe fire potential in forests near Eugene, Roseburg, Bend and the Portland area in Oregon. Other severe fires are forecast for parts of southwestern Idaho and parts of Montana. Unlike short-term weather forecasts, these projections are ultim...

Single stem cells from bone heal a broken heart

... the Journal of Clinical Investigation the authors isolated these human cells at the single cell level and were able to differentiate them into all different cell types. When single human bone marrow–derived stem cells were allowed to divide to form a large population, they were transplanted into a rat model ...

Heart repair gets new muscle

...letal precursors of cardiomyocytes, or Spoc cells) isolated from the skeletal muscle of adult mice can turn into beating cardiomyocytes in a test tube within days of isolation. When these cells are injected into mice with heart damage, they migrate to the damaged tissue and differentiate into cardiac muscle c...

Leprosy microbes lead scientists to immune discovery

...e publication of Nature Medicine. The researchers isolated immune cells in blood samples from healthy people and exposed the cells to a component of mycobacteria. The large white blood cells known as monocytes rapidly differentiated into the two distinct cell types, forming the body's emergency response to t...

Biomarkers isolated from saliva successfully predict oral and breast cancer

...UCLA scientists reported that genetic "biomarkers" isolated in saliva predicted oral squamous cell carcinoma in about nine out of 10 cases. A recent study by this group, published in Clinical Cancer Research, disclosed similar predictive powers for head and neck cancers. "These results indicate that such bi...

Scientists discover that three overlapping signals in embryo help get the backbone right

...ryonic stem cell work. Noggin, one of the proteins isolated by the UC Berkeley research group, has been used i.... They also discovered xnr3, and other researchers isolated three more factors - chordin, follistatin and cerberus. While Harland and his UC Berkeley colleagues...

NIAID begins clinical trial of West Nile virus vaccine

...auci, M.D., director of the NIAID. WNV, initially isolated in Uganda in 1937, made its first U.S. appearance in New York City in 1999. The virus usually is transmitted to humans through the bite of a mosquito that has been infected after feeding on an infected bird or animal. The virus also can be spread thr...

Friendly bacteria in humans may protect against HIV

...cteria that target mannose, Tao and his colleagues isolated oral and vaginal lactobacilli from healthy humans and tested the ability of different strains to bind to baker's yeast, another microorganism coated with mannose-rich sugars. They found a small group of lactobacilli that bound to mannose and further ...

Secret of smallpox's success may lead to bioterror cure

...thogenic virus as well." The gene that Jacobs has isolated and eliminated from the mutants is a special adaptation of pox viruses that appears to help the viruses hide double-stranded RNA, a form of RNA that only viruses produce and that animal immune systems have learned to recognize. "It's what we call a ...

Two chemicals boost immune cells' ability to fight HIV without gene therapy

...HIV-infected cells. In this study, the scientists isolated immune cells from the blood of HIV-infected persons and cultured the cells with the chemical compounds. They were surprised to see that the compounds produced the same three changes in the cells as those created by the gene therapy. "Lo and behold, ...

Breakthrough isolating embryo-quality stem cells from blood

...ersistent non-healing wounds. Low-grade stem cells isolated from the patient's own blood are applied to the wound to kick-start the healing process. ...

Scientists generate patient-specific stem cells, Science study says

Scientists have isolated the first human embryonic stem cell lines specifically tailored to match the nuclear DNA of patients, both males and females of various ages, suffering from disease or spinal cord injury. The research is being released by the journal Science, which ...

SuperLigands - a database of ligand structures derived from the Protein Data Bank

Scientists have isolated the first human embryonic stem cell lines specifically tailored to match the nuclear DNA of patients, both males and females of various ages, suffering from disease or spinal cord injury. The research is being released by the journal Science, which ...

To Stop Evolution: New Way Of Fighting Antibiotic Resistance Demonstrated By Scripps Scientists

...stant bacteria could potentially spread beyond the isolated confines of a hospital and into the general population. If one could design drugs to halt the enzymes that make mutations in bacteria, this could be a way of combating the evolution of antibiotic resistance. The Dramatic Effect of LexA Inhibition ...

Future diabetes drugs may target new protein interaction

...could be targeted as well. PGC1, which Puigserver isolated and cloned in 1998 as a postdoctoral fellow at Harvard, controls gene expression in the liver and other tissues. In the liver, it triggers the conversion of fats into sugar, particularly when access to food is limited. But no one knew exactly how it ...

In the liver, it triggers the conversion of fats into sugar, particularly when access to food is limited. But no one knew exactly how it ...

Sugar beet virus mutation requires Texas touch

...s and Rush for help. They would see rhizomania in isolated spots in a few fields, but within a few years, it would spread across entire production areas, Rush said. His team responded by studying the ecological and epidemiological aspects of the pathogen and disease ?what could producers do to reduce the inc...

Computational verification of protein-protein interactions by orthologous co-expression
