Winning combination to build bone density in children
...laying tag, jumping rope, etc. "You don't have to jump rope for half an hour. That would be considered very hard. In reality we are talking about the sort of energy you would expect kids to expend when playing around outside with a ball or rope," said Dr. Eston. "A brisk walk at about 4 mph would do t...High resolution satellite imagery assists hunt for infectious 'kissing bugs'
...s and cavities by day, then emerge to climb walls, jump and glide to land on exposed flesh. Infected children respond best to treatment, but for medical interventions to be effective, the bugs have to be eradicated to avoid rapid patient re-infection. As part of a wider anti-Chagas campaign in the area, ...Viral suspect for amphibian decline traced to human spread through bait
... could be moving around, and whether or not it can jump between species," Collins said. The salamander virus is related to another iridovirus strain that is endemic in frog populations. But preliminary analysis by the team has found that the salamander-killing virus is even closer to a virus found in spor...OHSU-VAMC study sheds light on estrogen's benefit for MS
...han normal, Offner said. Scientists attribute this jump to the body's natural defense against its own immune system, whose reaction to self-antigen proteins, or "self-Ags," in fetal tissue can lead to fetal rejection, as well as the chronic inflammation that is the root of autoimmune disease.

For instance, he said, "previous experiments in other laboratories suggest that steroid hormones may also play a role in causing some of the reported changes in h...Vioxx in high doses causes hypertension
...only in packages of five. "You hate to make people jump through hoops to get things but it should be harder to prescribe drugs that would potentially do harm."

Next they must migrate through the bloodstream to a distant site, exit the bloodstream, and establish new colonies.

"This is the type of quantum jump in crop yield needed at the continental scale to ensure food security in Sub-Saharan Africa," said Lal, who is also a professor of natural resources. "Soil needs enough carbon in order to hold water and nutrients and to grow crops efficiently. "But c...Study of proteins offers insights into organization of biological networks
...be like a 'Related Links' icon that enables you to jump from one home page to another." Researchers hope to determine whether this pattern holds for other types of cells as well and, ultimately, whether it provides insights into how gene systems go awry in cancer and other diseases. ...Super-effective 'jumping gene' created
...difficult to know where or when -- or even if -- a jump has happened. In a second paper in the same issue of Nature, M.D./Ph.D. candidate Jeffrey Han and Boeke report that the human jumping gene is relatively lethargic because its instructions are hard for cells to read. By replacing some of the gene's ...Researchers make major gain in understanding how prions jump species
...e of mad cow and related diseases, change shape to jump from one animal species to another. In test tube experiments, they were able to make human prion proteins exhibit characteristics of mouse prions or hamster prions through the substitution of either one or two amino acids. Furthermore, they describ...Missing gene a potential risk factor for birth defects
...product of the body's production of energy but can jump to toxic levels when cells are exposed to certain drugs, environmental chemicals and agents such as ionizing radiation.
