Nitric oxide: Key to cardiovascular and pulmonary function and drug effectiveness

...atment of human diseases." "In broad terms, the results of these experiments present a novel role for nitric oxide in regulating the activity of G-protein coupled receptors," Lefkowitz said. "Also, the findings point to the possibility that deficiencies in the activity of nitric oxide, which occurs in com...

Maggots rid patients of MRSA

...treatment. Professor Boulton, who published the results in the journal Diabetes Care, has now been awarded a £98,000 grant by Diabetes UK to carry out a randomized controlled trial to compare this treatment with two others. "Maggots are the world's smallest surgeons. In fact they are better than surgeo...

A frown or a smile? Children with autism can't discern

...to what is significant,?Davies said. While the results show the key role of eye gaze in signaling communicative intent, it also shows that autistic children, even when gazing directly into someone’s eyes, don’t recognize visual cues and don’t process that information. That may be why children diagnosed w...

An ancient bathtub ring of mammoth fossils

...iver Gorge—all in a matter of days. Preliminary results place most mammoth finds in the Lake Lewis area at elevations of 600 to 1,000 feet, which echoes the distribution of boulders that originated from far away—so-called erratics—and rafted in on icebergs. The evidence suggests that these elevations mirr...

Students invent protective pouch to enhance cell therapy

...oject is important because it could lead to better results from cellular therapy, in which live cells are injected to repair or replace damaged or depleted tissue. "It’s a device," Bulte said, "that allows the microcapsules to be removed and reinserted if additional therapy is needed ?a ‘yearly refill,?for e...

Risk of lymphoma increases with hepatitis C virus infection

...o military veterans who used the VA system, so the results may not be applicable to the overall U.S. population. The study population was mostly men (97 percent), the majority of patients were white, and the average age was 52 years. Patients in the HCV-infected group were more likely to have served during ...

Scientists identify prion's infectious secret

...tides and a prion taken from pathogenic fungi. The results were the same. Both prions also maintained a rigid species barrier. The baker’s yeast prion could not recruit peptides from the pathogenic fungi cells, and vice versa. To further verify these results, Tessier accessed a synthetic yeast prion,...

Egyptians, not Greeks were true fathers of medicine

...ie David, Director of the KNH Centre, said: "These results are very significant and show that the ancient Egyptians were practising a credible form of pharmacy long before the Greeks. "Our research is continuing on a genetic, chemical and comparative basis to compare the medicinal plants of ancient Egypt ...

The quarry, which lies to the north of Barcelona, was still active until fairly recently, but there are now plans to make it a protected site of special scientific interest.

Survival of the rarest: Fruit flies shed light on the evolution of behavior

...tition." More generally, Fitzpatrick says these results may help explain why genetic variants such as these are common in nature. "In the case of fruit flies, one variant encourages the survival of the other. In essence, there is not one best type of fly," he says. If this process is common in nature, it ...

Researchers publish first marsupial genome sequence

... non-gene regions is still being revealed. The new results suggest that mammals evolved not so much by inventing new kinds of proteins, as by tweaking the molecular controls that dictate when and where proteins are made. Second, many of the new DNA instructions appear to be derived from transposons, ...
