Researcher to study astronaut bone loss for space biology agency

...technology team, he will collaborate in person and via teleconference with NSBRI colleagues. He and the other two Fellows were chosen from among a nationwide pool of applicants. "The loss of mechanical forces on bone in the weightlessness of space dramatically weakens bone," says Long. "The ability of...

Scripps research team discovers a chemical pathway that causes mice to overeat and gain weight

...ack of a particular type of inflammatory signaling via EP3R with leptin and insulin increase, glucose tolerance, and white fat accumulation, and thus may provide a very important animal model for determining the importance of inflammation in obesity and in the conversion of obesity to type 2 diabetes." ...

Paleontologists discover new mammal from Mesozoic Era

...e attempted to understand the evolutionary pathway via which these precursor jaw bones became separated from the jaw and moved into the middle ear of modern mammals. "Now we have a definitive piece of evidence, in a beautifully preserved fossil split on two rock slabs," said Luo. "Yanoconodon clearly ...

Researchers from the UGR use a bacterium to obtain biopreservatives from food

...ida' (Characterization of enterocin AS-48 variants via site-directed mutagenesis), explains that AS-48 is a bacteriocin (protein substance with antimicrobial activity) produced by Enterococcus faecalis S-48. "The bacteriocin is characterized by its circular structure —that is, because of the joining of i...

Finnish scientists discovered a new approach to treat virus-induced lymphomas

...lopment by inducing cell-cycle arrest or apoptosis via a complex signal transduction network referred to ...s. These results demonstrate that p53 reactivation via Nutlin-3a is an efficient treatment for KSHV-lymphomas in mice and suggest a novel therapeutic strat...

Scientists discover a new risk factor for Alzheimer's

...oup of Israeli Arabs. They tracked the SORL1 genes via single nucleotide polymorphisms, or SNPs, which are single-letter changes in a gene's sequence. They found that the Caucasians with Alzheimer's displayed a certain SNP signature at one end of the gene, while the African Americans, Hispanics, and Isra...

Intravenous nanoparticle gene therapy shows activity in stage IV lung cancer

...d into the tumors of stage 4 lung cancer patients via an intravenously administered lipid nanoparticle in a phase I clinical trial at The University of Texas M. D. Anderson Cancer Center. The gene, FUS1, also was found to be active in the metastatic non-small cell lung cancer tumors. "We've treated ...

Protein found to shield pancreatic cancer cells from self-destruction

...m to kill themselves. In apoptosis, the cells die via damage to their nucleus and DNA, with other cellular organelles preserved. Autophagy kills by degrading those other organelles while sparing the nucleus. Mehta's lab reported in a Cancer Research paper last September that TG2 overexpression also a...

Active ingredient in common Chinese herb shown to reduce hypertension

...rioles in the hamster cheek pouch microcirculation via enhanced expression of endothelial nitric oxide synthase. The topical application of tanshinone IIA at one ¦Ìg/ml and five ¦Ìg/ml caused significant dose-related vasodilation, indicated by the increased agent/control ratio of arteriolar diameters fro...

Deep in the ocean, a clam that acts like a plant

...e is that while plants get their energy and carbon via photosynthesis by chloroplast symbionts, this clam gets its energy via chemosynthesis," said Jonathan Eisen, a professor at the UC Davis Genome Center and an author on the...

Mitochondrial genes move to the nucleus -- but it's not for the sex

...he nucleus -- in the production of eggs or pollen, via meiosis. But the mating system determines whether or not this separation is permanent. With self-pollination, the components separated by meiosis are brought back together. In contrast, the components are further separated if they mix and match hapha...

Turtles are loyal in feeding as well as in breeding

... they are able to return to exactly the same sites via very similar routes. We do not yet know why they return to the same sites, but these findings give us a much better picture of the behaviour of adult turtles at sea, where they spend the majority of their life cycle.' Scientists have long known th...

Study finds mercury prevalent in many western fish

...d on the OSU campus. Mercury entering the water via the atmosphere has a variety of natural and manmade sources, the researchers say, including coal power plants from as far away as China, the burning of heavy oils and other fossil fuels, and even forest fires. In the survey, the researchers did fi...

Many couples choose to donate surplus embryos for stem cell research

... designed to quantify the number of frozen embryos via questionnaires sent to couples before or shortly after their IVF cycles. In the current study, the couples, who had undergone IVF at least 3 years earlier, were presented with four options for the fate of their surplus embryos. The researchers fou...

Widely used iron nanoparticles exhibit toxic effects on neuronal cells

...and facilitates their engulfment by the PC12 cells via an inward pouching of the cell membrane called endocytosis. What happened next was a surprise. Jin's group had initially investigated the nanoparticles for use in in vitro studies as a possible way to manipulate nerve cells remotely with magnetic ...

Brain works more chaotically than previously thought

...i.e. only with those with which they are connected via synapses. This concept is the basis of the notion that neuronal information in the brain, somewhat like electricity in a computer, only spreads directionally in the brain, following specific ordered circuits. Too much glutamate is the death of ce...

MIT device draws cells close -- but not too close -- together

...ired by MEMS devices. Because cells communicate via signals transmitted both through the touching of cell membranes and through soluble molecules that flow between separated cells, biologists need to vary the spacing of cells to study their interactions. Also, since some signals induce a cell to chang...
