Good news: As you age, leg blood vessels adapt so you can still exercise without fainting

...n older adults, he said. Next steps and funding: The researchers will be conducting similar experiments in women (both on estrogen replacement and not). They plan to study the mechanisms underlying age-related changes in vascular responsiveness to sympathetic stimulation; and to exam...

HHS awards $232 million in biodefense contracts for vaccine development

...y Thompson said. "These new contracts are the next steps in our plans to build a robust stockpile of critical medical countermeasures and supplies, so we are even more prepared to respond to a biological attack or outbreak." These awards respond to a key objective of the NIAID biodefense research agenda...

Researchers provide road map for generating B cells from stem cells

...embryonic stem cells, HSCs have already taken some steps in differentiation and are committed to producing various types of blood cells. "This is a wonderful model system," Singh said. "We know more about the differentiation of B cells and red cells than other cell types in the blood system." After a seri...

Dr. Harris receives NIH Javits Neuroscience Investigator Award

...enable learning and memory in humans. "That is two steps beyond this grant," says Dr. Harris, who already is working with MCG colleagues to apply for an NIH Program Project grant that may take at least one of those steps. "Right now, we only know that it would explain the amount of LTP that we get in the c...

New DNA repair enzyme makes mistakes to save lives of cells

...own enzyme that orchestrates not only one, but two steps involved in bypassing common types of DNA damage. POL-Q is one of 15 different DNA polymerases in human cells. These specialized enzymes carry out the duplication, proofreading and repair of DNA. DNA is a double-stranded molecule that contains genes...

Molecule that helps DNA replicate may make good target for cancer therapy

...plicable to humans, Bielinsky said. Among the next steps for her lab is to find exactly how Mcm10 interacts with the polymerase alpha complex, because disrupting this interaction in a cancer cell might prevent it from multiplying. Also, the researchers want to know what it is in the cell that causes the de...

ENCODE consortium publishes scientific strategy

... scientific achievements, these are only the first steps toward the ultimate goal of using information about the human genome sequence to diagnose, treat and prevent disease. Over the past several years, researchers have made major strides in using DNA sequence data to help find genes, which are the parts ...

Cars, not crops, should be chief targets in reducing greenhouse gases

...e emissions by 10 percent. Carbon sequestration steps include adopting no-till agriculture to retain crop wastes in the soil rather than letting them decay after plowing, and retiring croplands by paying farmers to revert them to grassland or forests. Carbon dioxide has been implicated in global w...

Researchers tracking sources of arsenic contamination in water

...scharge from groundwater into the stream are first steps to possible remediation and control, Schreiber said. "The change that occurs as anaerobic (oxygen-free) groundwater discharges to aerobic surface water impacts the transport of arsenic. Arsenic is more mobile under anaerobic conditions, while under a...

Research team discovers possible genetic mechanism behind congenital heart defects

...ely one out of 100 live births in Canada. The next steps for this research involve examining patients with congenital heart defects to see if they, like the mouse model, have this modified protein. Other members of the research team include the study's co-lead authors Dr. Heiko Lickert of the Samuel Lunenf...

New source for heart bypass replacement blood vessels: Fibrin-based TEVs

Next steps According to Stelios Andreadis, the team is preparing to submit a grant application to the National Institutes of Health "to improve vessels' mechanical strength." They will also seek to make the matrix stronger using recombinant DNA techniques and ...

Grants target better predictors for type 1 diabetes

...odified in further steps. So you look at different steps to look for other markers." Dr. She predicts that the better treatment and potential cure that ideally result from the studies will be as multidimensional as Dr. Podolsky's model."I think there are going to be different interventions for dif...

Sex-determining genes of infectious fungus resemble human Y chromosome

...region appears to have acquired genes in four main steps -- beginning with the acquisition of genes into two separate sex-determining regions that later fused, the team reported. Furthermore, they found that the fungal sex-determining genes exist in clusters of functionally related genes. For example, gene...

Acetaminophen shows positive in vivo cardioprotective effects in heart attack, arrhythmia

...in only one of the treated dogs. Caveats and next steps Given the significance of their findings, the authors put forth this caution: "Metabolism of acetaminophen by dogs is different than in humans. Therefore, the results obtained at the doses used (30 mg/kg) might be only applicable to dogs and not to ...

By impounding iron, FHC foils cell suicide, fuels inflammation

...xygen radicals, cells are unable to take the final steps toward programmed cell death. "The data indicate that the antioxidant activity of FHC involves iron sequestration and that this sequestration is crucial for suppression of death of white blood cells induced by proinflammatory factors," the authors ...

UCSD discovery opens new avenues for design of anti-tumor medications

...chemical signals, we still need to tease apart the steps involved in the response," says Johnson. "It will also be important to understand how the signals sent out by the tumor, to stimulate the endothelial cells to grow toward it, differ from the signals that the endothelial cells themselves use to stimu...
