Compounds known to play an important role in how insects develop from larvae to adults have been shown in a mouse model for congestive heart failure to be effective in preventing and reducing cardiac cell overgrowth and irregular heart rhythms, according to UC Davis research published in the early online edition of the Proceedings of the National Academy of Sciences.
An enzyme inhibitor that regulates insect larvae development reduces heart enlargement and irregular heart rhythms in a mouse model, a 16-member University of California, Davis research team has discovered. The work, published in the current edition of Proceedings of the National Academy of Sciences, could lead to important new medications to treat human heart patients.
Using advanced new microscopy techniques in concert with sophisticated transgenic technologies, scientists at The Wistar Institute have for the first time created three-dimensional, time-lapse movies showing immune cells targeting cancer cells in live tumor tissues. In recorded experiments, immune cells called T cells can be seen actively migrating though tissues, making direct contact with tumor cells, and killing them.
Researchers at the Stanford University School of Medicine discovered that when a molecule responsible for dialing down the immune system malfunctions in the brain cells of mice, the rodents develop symptoms of the degenerative brain disease.
Cincinnati scientists have found further evidence that certain defensive white cells in the body cause or play a major role in the symptoms experienced by asthma patients.
Scientists at UC Irvine have determined that levels of atmospheric methane — an influential greenhouse gas — have stayed nearly flat for the past seven years, which follows a rise that spanned at least two decades.
Body armor with greater ballistics resistance is the aim of the research being carried out by Youqi Wang, associate professor of mechanical engineering at Kansas State University, with support from two US Department of Defense agencies.
Researchers at the Johns Hopkins Bloomberg School of Public Health’s Malaria Research Institute have developed a new test for detecting the malaria parasite in human urine and saliva. Although not a diagnostic test for determining treatment, the method could potentially reduce the need for blood sampling in epidemiological studies where large-scale malaria screening is required.
For people unable to simultaneously rub their stomach while patting their head, a new twist may be at hand. Touch, rather than concentration, could let people multi-task with their hands, and this may also potentially help improve the performance of people with coordination problems, according to psychologists.
Researchers from Georgetown University’s Institute for Reproductive Health report in November issue of Journal of Midwifery & Women’s Health that new natural family planning methods, also known as fertility awareness-based methods, fits well with philosophy of nurse-midwives and the needs of the women they serve.
