Association of herpesvirus with lung disorder questioned

...study, investigators in Japan found no association between a herpesvirus infection and a potentially life-threatening form of high blood pressure, as reported in the March 1 issue of The Journal of Infectious Diseases, now available online. The researchers reported that they were not able to detect human he...

Scientists ID molecular 'switch' in liver that triggers harmful effects of saturated and trans fats

... report, it wasn't clear what the differences were between saturated fats and unsaturated fats in their ability to raise cholesterol blood levels," commented Jeffrey Flier, MD, an obesity specialist at Beth Israel Deaconess Medical Center. "These are important findings in a long-established area of medicine....

UCSB scientists probe sea floor venting to gain understanding of early life on Earth

... here and perhaps elsewhere." The direct linkages between life and planetary processes on the volcanically active, deep-sea, mid-ocean ridge system can only be understood through tightly integrated studies across a broad range of disciplines in geophysics, geology, chemistry, biology, and oceanography, acco...

Source of molecular triggers in cutaneous T cell lymphoma identified

...ry system mimicking the tight relationship in vivo between CTCL cells and LC. The research team considered three broad categories of antigen as the source of the signal: the protein products of tumor viruses, of mutated genes, and of normal but usually inactive genes. The study reports that CTCL develops fr...

Yellowstone microbes fueled by hydrogen, according to U. of Colorado study

... hot springs' colors are the result ofinteractions between minerals and the microbes living in the pools.Hotter water usually shows colors from minerals, and cooler water playshost to photosynthetic pigments."Based on what I've seen in this analysis, I think hydrogen probablydrives a lot of life in a lot of ...

It's not all genetic: Common epigenetic problem doubles cancer risk in mice

...nberg and others have already noted an association between loss of imprinting of IGF2 and colon cancer in people, the current experiments were designed to find out whether the loss of imprinting is involved in cancer's development or just in its progression. "Most researchers, including me, expect epigeneti...

Novel technology detects human DNA mutations

...y. This method sandwiches a target DNA SNP segment between two oligonucleotide sequences to greatly increase detection specificity and sensitivity. One segment identifies any mutations in the DNA and the probe, a highly sensitive gold nanoparticle, creates a strong signal accurately indicating the presence o...

New, automated tool successfully classifies and relates proteins in unprecedented way

...database curators, and this is often notconsistent between different curators," said Murphy.Murphy and his colleagues are currently amassing more protein imagedata using CD Tagging so that they can refine their approach further.They are also working on ways to "train" a general system that willwork for diffe...

Poor prenatal nutrition permanently damages function of insulin-producing cells in the pancreas

...r meals. At age 2 months, the results were similar between the two groups. But over time, differences began to unfold. When 4 months old (comparable to human adolescence), the low-birth-weight babies began showing higher levels of blood glucose. "By 6 months, these levels had spiked abnormally, to 500 mg/dl ...

Neuronal 'traffic jam' marks early Alzheimer's disease

...akes it clear there is some mechanistic connection between the transport deficit and plaque deposition. "So, our hypothesis is that in familial Alzheimer's disease -- or in disorders such as Down syndrome where beta-APP is overexpressed -- those defects cause early failure in cellular transport," he said.

More research isneeded to understand the optimal conditions for preparing human cellsfor therapeutic applicat...

Genome of deadly amoeba shows surprising complexity, evidence of lateral gene transfer

...enes sheds new light on the unusual shared biology between the parasitic amoeba and anaerobic gut bacteria. The E. histolytica genome sequence is expected to help in the development of new vaccines as well as diagnostic tests that can distinguish the amoeba's most deadly strains. The parasite infects an est...

The protein complex triggers communication between molecules along a pathway that leads to the creation of long protein strings, called actin filaments, that are necessary for cellular growth, said Dan Szymanski, agronomy associate professor and lead author of the study. Knowledge of the biochemical ...

Plants respond similarly to signals from friends, enemies

...ship appeared when Weerasinghe studied the signals between plants and nematodes, even though the nematode provides no benefit to its host. Root-knot nematodes form feeding cells ?so-called giant cells ?in the plant and later galls or knots on it. "We don't know the precise structure of Nematode factor, but ...

Scientists Replicate Hepatitis C Virus in Laboratory

...single-strand RNA genome. They placed the DNA copy between two ribozymes, RNA molecules that have enzymatic function and can cleave RNA sequence at specific locations. These two ribozymes were designed to generate the correct ends of the HCV genome and to act as start and stop buttons to gene activity. The c...
