A comprehensive program to reduce or prevent childhood obesity in low-income communities led to significant improvements in obesity-related measures among children cared for at a Massachusetts community health center.
A large-scale effort to reduce childhood obesity in two low-income Massachusetts communities resulted in some modest improvements among schoolchildren over a relatively short period of time, suggesting that such a comprehensive approach holds promise for the future, according to a new study from Harvard T.H. Chan School of Public Health.
Opioid-related deaths have surged in the United States during the past two decades as the nation battles an opioid epidemic. A new study finds that following three guidelines in providing medical care to people with an opioid addiction may cut deaths among such patients by as much as one-third. While the results need to be duplicated, researchers say the initial findings suggest the quality measures could go a long way toward improving patient outcomes.
After showing that individuals who take levodopa, or l-dopa, for movement disorders such as Parkinson's disease are protected from developing macular degeneration, University of Arizona researcher Brian S. McKay, PhD, is taking the next step in his quest to prevent the blinding eye disease, thanks to a $1.7 million R01 grant from the National Eye Institute of the National Institutes of Health.
A team of MIT and Stanford University researchers has developed a way to label neurons when they become active, essentially providing a snapshot of their activity at a moment in time.
Mount Sinai researchers find this network central to Alzheimer's disease susceptibility.
Social isolation in the fruit fly Drosophila melanogaster, leads to sleep loss, which in turn leads to cellular stress and the activation of a defense mechanism called the unfolded protein response.
In an effort to understand how single cells heal, mechanical engineer Sindy Tang developed a microscopic guillotine that efficiently cuts cells in two. Learning more about single-cell wound repair could lead to self-healing materials and machines.
Glycosylated proteins are often overexpressed in tumor cells and thus could serve as tumor markers, especially those with the interesting molecule sialic acid as their sugar moiety. In the journal Angewandte Chemie, American scientists now report on a bioorthogonal labeling test for sialylated glycoproteins based on a glycoproteomics approach. This assay not only assesses the level of sialylated glycans in the tumor cell membranes, but also identifies up- or downregulated proteins directly in the prostate cancer tissue.
Just as people endlessly calculate how to upsize or downsize, bacteria continually adjust their volume (their stuff) to fit inside their membrane (their space). But what limits their expansion? The answer will suprise you.
