FDA Approves New Treatment for Chronic Hepatitis B

...f three studies in which Baraclude was compared to another anti-viral drug, lamivudine. In all three clinical studies, patients treated with Baraclude showed significant improvement in the liver inflammation caused by HBV and an improvement in the degree of liver fibrosis (scarring). In addition, a higher p...

Map of life on Earth could be used on Mars

...rom parents, but can transfer from one organism to another without reproducing by a process called lateral gene transfer. Modular metabolic genes, which are not critical for cell production, account for most lateral gene transfers between microbes. "There is a lot we're beginning to understand in terms of b...

Stem cell treatment improves mobility after spinal cord injury

...g ability -- one group seven days after injury and another 10 months after injury. In both groups, the early-stage cells formed into full-grown oligodendrocyte cells and migrated to appropriate neuronal sites within the spinal cord. In the rats treated seven days after the injury, myelin tissue formed as th...

UN pours polio vaccine into Yemen amid outbreak

Moffitt-USF head toward first human trials of anti-cancer drug that targets protein AKT

...iously discredited anti-cancer drug that could add another weapon in the arsenal against several cancers, including tumors of the breast, ovary, colon, skin and prostate. The compound, tricirbine, was tested at various cancer centers from 1982 to 1996 and found to inhibit some cancers, but researchers faile...

Ocean climate predicts elk population in Canadian Rockies

...he whole population. Also, wolves tend to kill one another as their available prey dwindles, so a stasis is maintained naturally. Nevertheless, Hebblewhite is excited about his findings because they provide a deeper understanding of the complex relationship between climate and ecosystem, and they open the d...

... realized," says Jeff Richey, UW oceanographer and another co-author. Carbon is carried by rains and groundwater into waterways from soils, decomposing woody debris, leaf litter and other organic matter. Once in waterways it is chewed up by microorganisms, insects and fish. The carbon dioxide they generate ...

Program finds lost genes in nematode genome

...Caenorhabditis elegans (C. elegans). The genome of another nematode C. briggsae, was also used to determine which parts of the sequence have changed since the nearest common ancestor of the two species. He found first of all that TWINSCAN predicted 60 percent of the genes in the C. elegans genome exactly, ri...

Fungus-farming termites descend from an African rain forest Eve

...ciency, fungus-farming termites resemble humans in another respect: just like the human female ancestor was African, so was the 'Eve' of fungus-growing termites, and just as humans later migrated out of Africa, so have fungus-farming termites. Evidence suggests they have colonised Asia at least four times. ...

Certain fish have a special mating preference

...al selection. "Male genitalia can be seen as just another morphological character, and if you think of them that way, females might be choosing just as they would for any morphological trait," he said. "This at least partially explains the variability in male genital morphology." Using this study as a spri...

Stem cell therapy successfully treats heart attack in animals

...igs. In just two months, stem cells harvested from another pig's bone marrow and injected into the animal's damaged heart restored heart function and repaired damaged heart muscle by 50 percent to 75 percent. The Hopkins findings, first presented last fall at the 2004 Scientific Sessions of the American Hea...

Improved statistical tools reveal many linked loci

...much data. Storey et al. compared their method to another statistical method, called two-dimensional linkage analysis, which tests for linkage between all pairs of a large set of genomic marker sites. The authors found that two-dimensional analysis is not only more computationally demanding than their new m...

Morphine for Chest Pain Increases Death Risk

...k of dying and 34 percent higher risk of suffering another heart attack while in the hospital. "This increase in mortality was present in every subgroup of patients we studied," Meine said. "What we found interesting was that patients given morphine were more likely to receive evidence-based medicine, were ...

UNC plant researchers discover proteins interact to form hair-trigger protection against invaders

... three different proteins work in concert with one another in tug-of war or teeter totter-fashion to keep plant defenses in a state of constant readiness," said Dr. Jeffrey L. Dangl, John N. Couch professor of biology in UNC's College of Arts and Sciences. Previously, he and others believed that the protein...

Researchers develop promising new gene network analysis method

"Genes influence one another in many intricate ways," said Leon Cooper, professor of physics and neuroscience and director of the Institute for Brain and Neural Systems at Brown. "What we need is a map, or network, of these links. What we've identified in this project is a more ...

Mechanism for the captation of nutrients in plants- unknown to date

...netration process independent of "endocitosis" and another dependent on "endocitosis" and which required approximately 90 minutes from the time the cell started to capture saccharose in order to start functioning. That is, for these first 90 minutes, the saccharose penetrates using the transporter mechanism ...

Bioinformatics reveals new gene regulation system

...tion factors that bind the NrdR-box, the team used another comparative genomic tool called positional clustering. Positional clustering takes advantage of the fact that functionally related gene sequences (such as the genes for Nrd and its transcription factor) frequently inhabit the same 'neighborhood' of t...

When she did that, the green cells were able to compete successfully and formed longer, more complex arbors. Although this work specifically examined the brai...
