Discover the Science of Health
Infants and toddlers who have been treated for cancer tend to reach certain developmental milestones later than do their healthy peers, say researchers at the National Institutes of Health (NIH) and in Italy. The findings show that delays may occur early in the course of treatment and suggest that young children with cancer might benefit from such early interventions as physical or language therapy.
National Institutes of Health researchers and their colleagues have identified how resveratrol, a naturally occurring chemical found in red wine and other plant products, may confer its health benefits. The authors present evidence that resveratrol does not directly activate sirtuin 1, a protein associated with aging. Rather, the authors found that resveratrol inhibits certain types of proteins known as phosphodiesterases (PDEs), enzymes that help regulate cell energy.
These findings may help settle the debate regarding resveratrol’s biochemistry and pave the way for resveratrol-based medicines. The chemical has received significant interest from pharmaceutical companies for its potential to combat diabetes, inflammation, and cancer. The study appears in the February 3rd issue of the journal Cell [1].
In a move to re-engineer the process of translating scientific discoveries into new drugs, diagnostics, and devices, the National Institutes of Health has established the National Center for Advancing Translational Sciences (NCATS). The action was made possible by Congress’ approval of a fiscal year 2012 spending bill and the president’s signing of the bill, which includes the establishment of NCATS with a budget of $575 million.
Recent findings in mice suggest that blocking the production of small molecules produced in the body, known as epoxyeicosatrienoic acids (EETs), may represent a novel strategy for treating cancer by eliminating the blood vessels that feed cancer tumors. This research is the first to show that EETs work in concert with vascular endothelial growth factor (VEGF), a protein known to induce blood vessel growth. Together, EETs and VEGF promote metastasis, or the spread of cancer, by encouraging the growth of blood vessels that supply nutrients to cancer cells.
Children who start elementary school with difficulty associating small exact quantities of items with the printed numerals that represent those quantities are more likely to develop a math-related learning disability than are their peers, according to a study supported by the National Institutes of Health.
The children in the study who appeared to have difficulty grasping the fundamental concept of exact numerical quantities — that the printed numeral 3, for example, represents three dots on a page — went on to be diagnosed with math learning disability by fifth grade.
Other early factors correlated with a math learning disability were difficulty recalling answers to single-digit addition problems, distractibility in class, and difficulty understanding that more complex math problems can be broken down into smaller problems that can be solved individually.
