New genes implicated in rheumatoid arthritis

...new genes with a clear abundance in RA, this study supports the promise of microarray analysis to not only provide further insights into the genetic components of this inflammatory disease, but also to help identify candidates for therapeutic intervention. ...

Dartmouth study finds that arsenic inhibits DNA repair

...the body's ability to repair its DNA. "This work supports the idea that arsenic in drinking water can promote the carcinogenic effects of other chemicals," says Angeline Andrew, the lead author and a research assistant professor of community and family medicine at Dartmouth Medical School. "This is evidence...

UC Davis study finds HIV hiding from drugs in gut, preventing immune recovery

...ted with HAART. Unpublished data on these patients supports the current findings, said Thomas Prindiville, a gastroenterology professor at UC Davis and a co-author of the study. "What we continue to see is that restoration of immune function is more likely when treatment is started early," said Prindiville...

Cincinnati surgeons report new treatment for often-fatal injury

...e a strong seal." Once in place, the dual lining supports the weakened vessel walls and allows blood to continue flowing through the aorta without applying pressure to damaged area. "Our method gives emergency surgeons a reliable way to repair difficult injuries with readily accessible materials," Dr. Gigl...

Novel connection found between biological clock and cancer

... and cell division through cell cycle checkpoints, supports the clock's "integral role in basic cell biology," conclude the researchers." Their work can help advance understanding of cancer origins as well as the timing of anti-cancer treatment. ...

Value of services performed by insects tops $57 billion in US

...und that native insects are food for wildlife that supports a $50 billion recreation industry, provide more than $4.5 billion in pest control, pollinate $3 billion in crops and clean up grazing lands, which saves ranchers some $380 million a year. And these are "very conservative" estimates that probably rep...

Protein found to control tumor growth in certain breast cancers

...ights into the physiological functions of Nod1 and supports our contention that there is a clear link between Nod1 and estrogen sensitivity in these cells. Our future studies will assess the relationship between the pathway uncovered in breast cancer and other hormone sensitive malignancies. Those studies ma...

ASU researchers find link between social behavior, maternal traits in bees

Gene variation increases SIDS risk in African Americans

...nditions. Although, the authors note, this study supports a role of Y1103 in SIDS, and the previous use of mexiletine by patients with arrhythmias "suggests a strategy for prophylactic therapy," they stress that their results "need to be replicated and the risks and benefits of treatment assessed" before sc...

Growth factor-promoting angiogenesis expressed in tumor cells and normal neurons

... to tumor growth by setting up an environment that supports angiogenesis and tumor progression. The researchers demonstrate that decreased SCF expression in vivo results in decreased angiogenesis and improved survival in mouse glioma models, whereas overexpression of SCF is associated with a worse prognosis ...

Protecting endangered species helps reduce poverty

...le meat and eggs ever were. The community strongly supports conservation measures to promote ecotourism, and both turtle and tourist numbers have climbed over the past 30 years. Community forestry efforts in parts of Nepal have led to the restoration of vital habitat corridors for the survival of tiger popu...

Manipulating single cell receptor alters animal behavior

...take without increasing their water intake. "This supports our hypothesis that intracellular signaling pathways stimulated by the activation of angiotensin receptors can be separated based on behavioral relevance," he says, "something that had not been shown before." "Understanding how signaling pathways wo...

Diverse tropical forests defy metabolic ecology models

...stead, observed variation within and among forests supports alternative models presented by the CTFS team. Are tropical forest structure and dynamics too complex for universal explanations? "When you walk through different tropical forests, or graph data from different forests, there are certain features th...

CU, USDA team to curb two invasive, poisonous vines

...fective agent." Milbrath, whose funding from USDA supports the Cornell collaboration on a three-year project, is working with researchers at a USDA facility in Montpellier, France, and other colleagues who are working in Ukraine and southwestern Europe to identify the plants' natural enemies. The plants con...

High-tech tags on marine animals yield valuable data for biologists and oceanographers

But the 2004-05 season was marked by unusually warm water along the coast, and the sea lions were forced to change their diets and their foraging patterns, Weise said. "The sea lions disappeared from Monterey Bay, as di...

'Bad' enzymes may wear white hats after stroke

Feinstein researchers identify intelligence gene

... a small proportion of it -- about 3 percent. This supports a model involving multiple genetic and environmental influences on intelligence," said Anil Malhotra, MD, principal investigator of the study. The specific role of dysbindin in the central nervous system is unknown, but it is highly present in key b...

Underdogs in the understory: Study suggests nature favors rarer trees

"This research has the surprising finding that biodiversity in tropical rain forests and Minnesota prairies arises from the ...

MicroRNA may have fail-safe role in limb development

...opment, and this work is a solid contribution that supports that idea. Researchers have also been looking for differences between gene expression in forelimbs and hindlimbs, with little success. This paper suggests there is a new mechanism to control the fidelity of protein expression in the limbs through mic...
