Bone Density Recovers After Teens Stop Injected Contraceptive

...ped using DMPA, their average bone mineral density scores were “at least as high as those of the comparison women at all of the anatomical sites.?/p> The current study was conducted to follow up an earlier study of older women (18-39 years old.) That study found that the older women lost bone density wh...

Genrate: a generative model that finds and scores new genes and exons in genomic microarray data

...vidence derived from different sources and outputs scores (log-likelihoods) for each gene model, enabling the estimation of false-positive and false-negative rates. The model has a number of local minima that is exponential in the length of the DNA sequence data, so direct application of the EM learning alg...

Researchers discover underwater volcano

...vent area. As the submarine landed near this area, scores of eels, each approximately one foot in length, emerged from the rock caves and crevices. The scientists named this novel marine hydrothermal community "Eel City." "At this point we do not know why we found such extensive eel communities surrounding...

Depression gene may weaken mood-regulating circuit

... the same circuit. Nearly 30 percent of subjects' scores on a standard scale of "harm avoidance," an inherited temperament trait associated with depression and anxiety, was explained by how well the mood-regulating circuit was connected. "Until now, it's been hard to relate amygdala activity to temperamen...

Neurologix announces positive results of gene therapy clinical trial in Parkinson's disease

U-M researchers identify new blood test for prostate cancer

...es of 4-10 ng/ml or 2.5-10 ng/ml, intermediate PSA scores that do not always suggest cancer. The study authors suggest the 22 biomarkers could be used for patients in this range to help determine whether to undergo a biopsy. The new test requires only a routine blood draw for patients. Most blood-processin...

Swimming with dolphins can alleviate depression

...allowed to take drugs during the study. Depression scores were measured before the study and at the end of treatment. Although some participants dropped out of the study, the average severity of the depressive symptoms was more reduced in the experimental group than in the control group. Animal facilitat...

Inflammation and drugs to control this activity studied in a variety of tumors sites

...isk for developing cancer based on either high PSA scores or abnormal DREs. Of the 177 men, 144 or 81 percent were found to have chronic prostate tissue inflammation. The scientists categorized the biopsies based on pathology. They found that of the 144 cases, 15 percent (22/144) had only inflammation, 15...

New genetic test for breast cancer

...rano said. "But about 45 percent of women receive scores that range from 11 to 25, where the treatment path is not so clear. Our study is designed to resolve this uncertainty." Women participating in the TAILORx trial will be assigned to one of three groups depending on their recurrence score. If the sc...

Quitting smoking improves lung function considerably

...a, quitting smoking can improve lung function test scores by more than 15 percent in less than two months. The findings appear in the second issue for July 2006 of the American Journal of Respiratory and Critical Care Medicine, published by the American Thoracic Society. Neil C. Thomson, M.D., of the D...

UCLA study finds same genes act differently in males and females

...Even in the same organ, the researchers identified scores of genes that varied in expression levels between the sexes. Gender consistently influenced the expression levels of thousands of genes in the liver, fat and muscle tissue. This effect was slightly more limited in the brain, where hundreds, not tho...

Newborn screening can cause unnecessary parental stress

...and fathers in the false-positive group had higher scores on the standardized Parenting Stress Index (PSI); 11 percent of mothers (versus no mothers in the comparison group) scored in the clinical range, in which treatment might be prescribed. Waisbren and Gurian also found that false-positive tests affect...

...sion within a cell's nucleus. In plants, there are scores of genes involved in growth and development that can be influenced by brassinosteroids, Chory noted. "Many of these genes are predicted to be involved in growth, like cell wall metabolism. Their up-expression would be predicted to promote cell expa...

Fire ants: Their true story told by the scientist who loves them

From a list of S. invicta's most endearing qualities he cites abundance; there's no shortage of lab samples. It's a low-maintenance animal withou...

Salk scientists untangle steroid hormone signaling in plants

...his modified form of BES1 binds to DNA, activating scores of target genes. Referring to the work of Vert and other members of the brassinosteroid team, Chory says, "The old model may be out, but Greg's new studies, together with those of former postdocs, Yanhai Yin and Zhiyong Wang, have allowed us to unra...
