How the environment could be damaging men's reproductive health

...8 April) in Europe's leading reproductive medicine journal Human Reproduction, suggest that environmental pollutants could be changing the ratio of sperm carrying the X or Y (sex determining) chromosomes and that they could be contributing towards male reproductive disorders. A study by Swedish researchers[...

"Our use of medically important classes of antibiotics in food-animal production creates a significant public health concern," said the study's lead author Lance Price, a doctoral candidate and fellow at the Bloomb...

Live fast, die young true for forests too

...ey (USGS) study published in a recent issue of the journal Ecology Letters. This discovery could help scientists predict how forests will respond to ongoing and future environmental changes. "One implication of this fast turnover rate is that the world¹s most productive forests may be those likely to respon...

Not-for-profit publishers call NIH public access rule a missed opportunity

Pulsating ultrasound enhances gene therapy for tumors

...ssue, according to a study in the May issue of the journal Radiology. High-intensity focused ultrasound (HIFU) is more powerful than standard ultrasound. HIFU can destroy tumors through long and continuous exposures that raise the temperature inside cancerous cells, effectively "cooking" them. Under a techn...

Great White shark evolution debate involves WSU Lake Campus geology professor

... meetings in Mississippi and Colorado. A scholarly journal article on the subject is pending. The geologist joined the Lake Campus faculty two years ago, and one of the reasons he selected Wright State was the extensive opportunity for fossil research in this region of Ohio. ...

Viral protein influences key cell-signaling pathway

...he research is published in the April issue of the journal AIDS Research and Human Retroviruses. The study found that p12 increases the activity of an important gene in host cells. That gene controls production of a cell protein called p300. The p300 protein, in turn, controls a variety of other genes in ma...

Controlling protein diversity

...s in a report that appears in today's issue of the journal Molecular Cell. "A major question in biology today is how human cells with 30,000 genes produce at least 120,000 proteins," said Dr. Bert O'Malley, chair of the BCM department of molecular and cellular biology. The answer is a process called alternat...

NIH Calls on Scientists to Speed Public Release of Research Publications

...cript is defined as the final version accepted for journal publication, and includes all modifications from the publishing peer review process. The policy gives authors the flexibility to designate a specific time frame for public release ?ranging from immediate public access after final publication to a 12...

"We found that AIM is highly expressed in certain macrophages and that lack of AIM dramatically decreased early atherosclerotic lesion development in mice," Dr. Miyazaki said. "These results may imply a novel therapeutic application...

Transgenic plants remove more selenium from polluted soil than wild plants, new tests show

...The new research findings, published Feb. 1 in the journal Environmental Science and Technology, show that three transgenic lines of the Indian mustard plant, Brassica juncea, absorbed two to four times more selenium from contaminated soil than the genetically unaltered, wild-type plants. Researchers from t...

50-year-old Mystery Solved: Protein Tags Regulate Key Ion Channel

...covery, published in the 8 April 2005 issue of the journal Cell, answers a question dating back to the 1950s: How do cells control the background movement of potassium ions across the cell membrane? This process is important because the flow of potassium ions determines whether "excitable" cells in the brain...

Gene therapy promising for growing tooth-supporting bone

...ording to a new paper in the February issue of the journal Molecular Therapy. In a patient with a sizeable mouth wound, replacing a tooth takes more than simply implanting a new one---the patient also needs the bone structure to anchor the new tooth in place. Such reconstructive surgery today involves eithe...

Heart repair gets new muscle

Gray wolves maintain the food chain in winter

...n. But, in a new study from the open-access online journal PLoS Biology (www.plosbiology.org), Christopher Wilmers and Wayne Getz show that the impact of climate change on many different species in Yellowstone Park can be buffered by a top predator - the reintroduced gray wolf (Canis lupus). Gray wolves inh...
