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

...istance." "The endothelial cells are also in direct contact with the blood, simplifying the delivery of drugs," adds Tang. Because HIF-1alpha is usually turned off in endothelial cells, and the mice lacking the gene in blood vessels were healthy and had normal lifespans, the researchers think ...

GlaxoSmithKline awards $250,000 in research grants for research on drug therapies for HIV/AIDS

...RNA of some viruses. IRES regions are believed to direct the synthesis of viral proteins in host cells. Dr. Robertson and his colleagues have discovered a target site within the IRES regions of several viruses, allowing them to be inhibited by a host enzyme called RNase P. "Research by other scientists...

Researchers discover new way to boost grain crops' drought tolerance

...ll, including grains, which are the most important direct source of food for livestock and for a majority of humans. "Our discovery will assist farmers who depend on rainwater for their crops during those years when rainfall is low, particularly those who grow crops in arid areas, such as exists in many de...

Endurance running may be key to evolution of human body form

...elling us is that running evolved in order for our direct ancestors to compete with other carnivores for access to the protein needed to grow the big brains that we enjoy today." Protein and fat derived from prey are excellent food for growing the bodies and brains of predators; Lieberman suggests runnin...

UGA researchers explain recent decline in Georgia's blue crab population

...ds from crab to crab. Lee and Frischer found a direct correlation between the state's recent drought and the prevalence of the disease in the state's blue crab population. They also cite data showing that during times of high river flow, when the percentage of salt in the estuaries is lower, blue crab l...

'Lighter than air' breathing more than doubles COPD patients' exercise endurance

... 2002 was $32.1 billion, of which $18 billion were direct costs. COPD is characterized by shortness of breath (dyspnea) and exercise intolerance. Among severely affected patients, especially those with emphysema, the inability to exercise or even to move small distances is mostly due to limits on "breat...

Gene therapy shows promise in model of Parkinson's disease

...s could translate into the clinic either through a direct gene therapy approach or through the identification of small drugs which enhance the expression of the endogenous parkin." The next step, Lo Bianco notes, is to scale the system up to a primate model. The technique must be...

Citrus shows promise for certain childhood cancer

"There will be a direct impact of increases in summer temperature on reindeer well-being if global warming is allowed to proceed," said University of Washington archaeologist Donald Grayson, lead author of the study. "The number of southern reindeer will diminish dramatica...

UCSD biologists identify gene in corn plants that may have paved way for development of maize

Brain surface stimulation alleviates Parkinson's symptoms

...er motor cortex stimulation can be as efficient as direct stimulation of the deep-brain regions of the striatum, "the results obtained here in baboons strongly suggest that this may be the case."

Carnegie Mellon scientist develops way to deliver promising genetic tool into living cells

...ially could be used to control gene expression and direct what kinds of tissues these malleable cells ultimately become. By infusing GPNAs to block the translation of specific RNAs, researchers also could "down-regulate" the production of disease-related proteins. Scientists could use GPNAs to temporarily i...

New drug sidesteps Gleevec resistance in human trials

...fication of this compound as a drug candidate is a direct byproduct of understanding why patients develop resistance to Gleevec," said Sawyers. He notes that just as Gleevec was developed as a "molecularly targeted" inhibitor, the next generations of Gleevec, of which BMS-354825 is is one, are being refined...

Researchers discover direct link between agricultural runoff and massive algal blooms in the sea

Scientists have found the first direct evidence linking large-scale coastal farming to massive blooms of marine algae that are potentially harmful to ocean life and fisheries. Researchers from Stanford University's School of Earth Sciences made the discovery by analyzing satellite images ...
