11 hours ago Researchers from LSTM have found that a single genetic mutation causes resistance to DDT and pyrethroids (an insecticide class used in mosquito nets). With the continuing rise of resistance the research, published in the journal Genome Biology, is key as scientists say that this knowledge could help improve malaria control strategies. The researchers, led by Dr Charles Wondji, used a wide range of methods to narrow down how the resistance works, finding a single mutation in the GSTe2 gene, which makes insects break down DDT so it's no longer toxic. They have also shown that this gene makes insects resistant to pyrethroids raising the concern that GSTe2 gene could protect mosquitoes against the major insecticides used in public health. Mosquitoes (Anopheles funestus) are vectors of malaria, and most strategies for combating the spread of the disease focus on control of mosquito populations using insecticides. The spread of resistance genes could hold back efforts to prevent the disease. The authors say that knowing how resistance works will help to develop tests, and stop these genes from spreading amongst mosquito populations. Charles Wondji said: 'We found a population of mosquitoes fully resistant to DDT (no mortality when they were … Continue reading →

A stem cell based method may restore strength to damaged skeletal muscles of the elderly, according to a study done at the University of Toronto and published in a February 2014 issue of the journal Nature Medicine describes. A release from the university notes that skeletal muscles are some of the most important muscles in the body, supporting functions such as sitting, standing, blinking and swallowing. In aging individuals, the function of these muscles significantly decreases. The release quotes Penney Gilbert, Assistant Professor at the Institute of Biomaterials & Biomedical Engineering, as saying, You lose fifteen percent of muscle mass every single year after the age of 75, a trend that is irreversible." Through tracing the signaling pathways of the cells, Gilbert with lead author Professor Helen Blau and postdoctoral researcher Ben Cosgrove determined that during aging, a subpopulation of stem cells begin to express a modification of a protein that inhibits their ability to grow and make new stem cells. "But if we instead treated those cells outside the body with a drug that prevented that protein modification from occurring, in combination with culturing the cells on something soft that is reminiscent of soft skeletal tissue, like a hydrogel … Continue reading →

A Senate committee voted unanimously to renew a two-year pilot program that provides treatment for children with autism spectrum disorder. Shutterstock Enlarge photo SALT LAKE CITY A Senate committee voted unanimously Monday to renew a two-year pilot program that provides treatment for children with autism spectrum disorder. If the bill ultimately passes, HB88 would allow for autism services to be provided through a Medicaid waiver program and a public employees health plan. The program previously included an autism treatment account, but funding for the account ends in June. The Medicaid waiver covers about $29,000 a year of applied behavior analysis therapy for children ages 26. It also covers 10-15 hours of in-home therapy and up to three hours of respite for the family each week. Without renewal by the legislation, the pilot program will last through June. During the first year and a half of the pilot program, therapy enrollment increased and about 300 children received treatment. According to the Centers for Disease Control and Prevention, 1 in 47 individuals in Utah are on the autism spectrum the highest rate in the United States. Bill sponsor Rep. Ronda Menlove, R-Garland, said she anticipates a renewal of the Medicaid waiver would … Continue reading →
