Common alternative treatment for liver disease is found to be ineffective

...on-alcoholic liver disease. "The ironic fact is," notes Christian Gluud of the Copenhagen Trial Unit, Center for Clinical Intervention Research at the Copenhagen University Hospital, "that even though milk thistle and milk thistle extracts have been widely examined, we are still not in a situation where w...

Scientist uses form to explain function of key building blocks of life

... will be important for larger proteins." Markley notes that an undergraduate and graduate student played key roles in the study. Lin, who plans to complete her Ph.D. this spring, spent years tackling what Markley described as a "complex and difficult project." Erika Gebel, the undergraduate on the stud...

Synthetic Protein Eases Arthritis Symptoms in Mice

...TNFR-2 to continue to function. This is important, notes Dr. Lenardo, because it may represent an advantage over some currently used arthritis drugs, which directly block TNF-alpha by binding to both TNFRs and thereby inhibit beneficial actions mediated by TNFR-2. The scientists next aim to develop a more...

Missing fossil link 'Dallasaurus' found

...eries are made by highly trained paleontologists," notes Dallas Natural History Museum Curator Fiorillo. "The observant individual, even kids, can still make an important find," he says. "Once this goes mainstream, and people begin to recognize what mosasaurs are, we'll be finding more and more." ...

Earliest European Farmers Left Little Genetic Mark On Modern Europe

...ecting drug users in Spain and Brazil. The report notes that, without HIV prevention measures, about 35% of children born to HIV-positive women will contract the virus. While mother-to-child transmission has been virtually eliminated from industrialized countries and service coverage is improving in many ...

Fruit fly research set to revolutionize study of birth defects

...ournal in the habit of publishing insect studies," notes biologist Dr. Virginia Walker, who co-authored the study. "The neat thing about this work is that fruit flies treated with this drug show 'birth defects' that are hauntingly similar to birth defects in human babies. Babies have bent limbs, tufts of...

New genetic test can detect clam disease

...aches a critical concentration in the water. Gast notes that although red tide got a lot of media attention this year, QPX is actually a bigger problem. The toxins that cause red tide in clams and other shellfish in New England do not kill the shellfish and will wash away once the red tide bloom diminishe...

Scientists must offer solutions for conserving tropical forests in a rapidly changing world

...0-hectare plot every five years since 1985. Wright notes that the aboveground biomass on BCI was almost constant since the first census. But lianas increased substantially (from 9% to 13% of all leaf biomass) between 1986 and 2002. In another protected area, the Kibale National Park in Uganda, a 30-year r...

Sudden change in social status triggers genetic response in male fish, study finds

... that ultimately make him capable of reproducing," notes Fernald, the Benjamin Scott Crocker Professor of Human Biology at Stanford. This finding offers the first direct evidence that changes in social status also trigger cellular and molecular changes in the brain, he adds, which could have significant i...

Scientists characterize proteome of human cornea

...nd the cornea and are not produced in the cornea," notes Dr. Enghild. "Our results also showed that proteolysis and post-translational modifications of proteins are common events in the normal human cornea." Among the molecules that the scientists identified were proteins involved in antimicrobial defense...

HIV inserts into human genome using a DNA-associated protein

... sites within chromosomes," says Bushman. Bushman notes that finding that LEDGF is part of the cellular apparatus necessary for HIV replication is important to the field of gene therapy. Controlling where gene-therapy vehicles insert in the human genome could help make the delivery of new therapeutic sequ...

...h, but may have important practical implications," notes Wernegreen. "A very promising area of endosymbiont research is the manipulation of these bacteria to control host populations in the field." ...

Independent researchers confirm the existence of ivory-billed woodpecker

...rdings include a series of distinctive "kent" call notes and an exchange of the diagnostic "double raps" between two individuals. According to Mark Robbins of the University of Kansas, "The recordings of the double raps sound very natural, and are totally consistent with the behavior or the Central and Sou...

U-M scientists say fused genes trigger the development of prostate cancer

"The challenge of analyzing such a large dataset is enormous, since the integration of the different datasets is not a simple task," explained the research s...

Emerald Spectre haunts Ontario's ash forests

...y that beetles jumped the ash-free zone. The study notes that scientists still need to determine the maximum flight potential of adult borers. In Michigan, the borer was reported at 29 new sites in 2004. New infestations were also reported in Ohio and Indiana. The one bright spot in the study is the app...

"In pregnant women, the concentrations of these lipoproteins are particularly very high and it is thought that these lipoproteins are the forms that carry the lipids to the placenta. The researchers looked at several genetic variations (a...
