DNA mutations found to be biased toward favoring 'G-C' content. To make the iconic, twisted double helix that accounts for the diversity of life, DNA rules specify that G always pairs with C, and A with T. But, when it's all added up, the amount of G+C vs A+T content among species is not a simple fixed percentage or, standard one-to-one ratio.
A new state-by-state health analysis in India finds that over two decades heart- and lung-related conditions, as well as other non-communicable diseases (NCDs), have surpassed infectious diseases, such as diarrhea and tuberculosis, as the nation's leading killers. The extent of this difference, however, varies significantly among the nation's 29 states and seven union territories.
New study provides added insights as to why women become less sexually active as they age. As women age, sexual activity typically declines. But that doesn't necessarily mean they are no longer interested in sex. The problem for many is physical.
Researcher’s team revealed that in laboratory tests and animal models, trehalose develops the virulence of epidemic C. difficile lineages that predominate in patient infections. An increasing frequency and severity of healthcare-associated outbreaks caused by bacterium Clostridium difficile have been linked to the widely used food additive trehalose. This study has been published in Journal Nature.
New dipstick technology that enables pathogen detection and the rapid diagnosis of human, animal and plant disease in even the most remote locations has been developed by University of Queensland scientists.
Researchers say there is an urgent need for action after 95% of children from 12 primary schools in Dhaka tested positive for recent second-hand smoke (SHS) exposure. The study results are published in the journal Nicotine & Tobacco Research and the study was funded by the Medical Research Council.
A typhoid conjugate vaccine has been prequalified by the World Health Organization (WHO), bringing the vaccine one step closer to reaching millions more people at risk of typhoid.
Typbar-TCV, a Vi-tetanus toxoid conjugate vaccine manufactured by Indian company Bharat Biotech, is the first typhoid conjugate vaccine to achieve WHO prequalification. The vaccine, which is currently licensed in India and Nepal as a single, intramuscular dose, has been shown to elicit a robust immune response in infants as young as six months of age.
Researchers study the clinical features and explore if the presence of biofilm, nasal polyps or other disease individual could serve as predictor for the symptomatic load. A patient group undergoing septoplasty without disease of the sinuses was included as control. Patient population undergoing functional endoscopic sinonasal surgery (FESS) for chronic rhinosinusitis, CRS patients with or without nasal polyps are a heterogeneous group with various phenotypes and characteristics such as allergic rhinitis, eosinophilic inflammation, fungal allergy.
Professor of medicine at Harvard Medical School and Brigham and Women's Hospital told that, they generally agree with the approvals of the Task Force against the use of menopausal hormone therapy for the express purpose of trying to prevent cardiovascular disease or other chronic conditions. They have heard from many clinicians and patients that that's the case and that this is leading to confusion. This report was published in JAMA.
The heart cells’ ability to produce energy could be disrupted if the heart consists of excess fat levels. The researchers from the University of Iowa study identified this condition. Researchers believe the mechanism may contribute to the two- to five-fold increased risk of heart failure in people with diabetes.
According to a study, more than half also were punished last year through the penalty, which was created by the Affordable Care Act and began four years ago. The program is designed as a financial incentive for hospitals to avoid infections and other mishaps, such as blood clots and bedsores. Hospitals that treat large proportions of low-income people also were fined more than hospitals with a more affluent patient base, the analysis found. About a third of those safety-net hospitals were penalized.
Results of a new randomized, double-blinded, controlled clinical trial in veterans showed a 75% reduction in the risk of needing surgery to treat a squamous cell carcinoma for a year after applying a skin cream for up to four weeks. The new results are published in JAMA Dermatology.
