Cardiac fibrosis involves an increase of connective tissue in the cardiac muscle, causing a loss of function. Researchers at the Technical University of Munich (TUM) have now discovered that fibrosis occurs less frequently when microRNA 29 (miR-29) is suppressed in cardiac muscle cells. Older studies had suggested that it was in fact low levels of miR-29 that caused fibrosis. The new insights point to potential new approaches for developing drugs against fibrotic diseases.
Amid mounting controversy over use of neonicotinoids and declining bee population, a new analysis by U of G scientists of previously unpublished studies and reports commissioned by agri-chemical companies Bayer and Syngenta -- as well as published papers from the scientific literature -- shows no significant ill effects on honeybee colonies from three common insecticides made by the companies.
New research suggests that few people, if any, should be asked to leave their homes after a big nuclear accident, which is what happened in March 2011 following the Fukushima Daiichi nuclear disaster.
Someday, left-over toner in discarded printer cartridges could have a second life as bridge or building components instead of as trash, wasting away in landfills and potentially harming the environment. One group reports in ACS Sustainable Chemistry & Engineering that they have devised a method to recycle the residual powder in 'empty' cartridges into iron using temperatures that are compatible with existing industrial processes.
A new study of mice by scientists at the University of Illinois raises concerns about the potential impact that long-term exposure to genistein prior to conception may have on fertility and pregnancy. The study was conducted by food science and human nutrition professor William G. Helferich, comparative biosciences professor Jodi A. Flaws, Illinois alumna Shreya Patel and animal sciences research specialist James A. Hartman.
A new study concludes that two of the top medications available for outpatient, office-based treatment, once initiated, are equally safe and effective in curtailing opioid use, relapse, treatment drop-out and overdose.
People who overdose on paracetamol could be helped by a blood test that shows immediately if they are going to suffer liver damage, research led by the universities of Edinburgh and Liverpool has found.
Université de Montréal research reveals that 29 pregnant women living near natural-gas hydraulic fracturing sites had a median concentration of a benzene biomarker in their urine that was 3.5 times higher than that found in women from the general Canadian population.
University of Leicester and Medical Research Council researchers lead study to monitor effectiveness of drugs on cancer patients.
Scientists and activists alike have been looking for a solution to the problem of aquatic nutrient pollution. Now one group reports in Environmental Science & Technology that ribbed mussels are up to the clean-up challenge.
