A bite from a lancehead snake can be fatal. Species in the family, found throughout Central and South America, have venom that can disrupt blood clotting and cause hemorrhage, strokes and kidney failure.
BOSTON -- Researchers from Hebrew SeniorLife's Institute for Aging Research, Boston University, Beth Israel Deaconess Medical Center, and University of Calgary have found evidence that weight loss can result in worsening bone density, bone architecture and bone strength. The results were published in the Journal of Bone and Mineral Research.
TUCSON, Ariz. - Nighttime snacking and junk food cravings may contribute to unhealthy eating behaviors and represent a potential link between poor sleep and obesity, according to a study by University of Arizona Health Sciences sleep researchers.
The study was conducted via a nationwide, phone-based survey of 3,105 adults from 23 U.S. metropolitan areas. Participants were asked if they regularly consumed a nighttime snack and whether lack of sleep led them to crave junk food. They also were asked about their sleep quality and existing health problems.
New research at this year's Euroanaesthesia congress in Copenhagen, Denmark, suggests that nail treatments such as acrylic nails or nail polishes do not, as previously thought, affect readings from digital pulse oximetry (DPO) devices used to monitor patients' blood oxygen saturation (SpO2) levels in hospital.
New research presented at this year's Euroanaesthesia congress in Copenhagen, Denmark, shows that giving women different types of virtual reality (VR) sessions prior to sedation for IVF treatment (to become pregnant) reduces their anxiety and could improve successful pregnancy rate. The study is by Professor Fabienne Roelants, Saint-Luc Hospital, Catholic University of Louvain, Brussels, Belgium, and colleagues.
Around two to six per cent of all people with obesity develop obesity already in early childhood; it's in their genetic cards. Obesity-causal mutations in one of their 'appetite genes' gives them a strong genetic predisposition for developing obesity, also called monogenic obesity. Their experience of hunger is overruling and their feeling of satiety limited.
A specialized fat molecule, called cardiolipin, that is made within the body's own fat cells, is far more significant to the body's overall state of health than previously realized.
Large amounts of cardiolipin produced in the fat cells' mitochondria - or so-called powerhouses - result in stronger calorie-burning while low amounts of the molecule are related to obesity and type 2 diabetes, a new study conducted at the University of Copenhagen shows.
The persecution of wolves in order to remove them from human settlements has culminated in their near-disappearance in numerous European countries, like Spain and Sweden. Following a recovery of the species, a team of scientists has determined what geographic areas in the Scandinavian country would be most suitable for a redistribution of the specie's range, in the interests of increasing the social acceptance of wolves.
During the first days of life, the heart of a newborn mouse adapts to entirely new physiological conditions, larger volume loads and an increased energy demand. As a result, fundamental changes occur in the heart. Studies have shown that the heart of neonate mouse retains its ability to effectively repair tissue damage. This ability of the cardiac muscle to regenerate, however, gradually disappears during the first week of life.
Green tea could hold the key to preventing deaths from heart attacks and strokes caused by atherosclerosis, according to research funded by the British Heart Foundation and published in the Journal of Biological Chemistry.
Scientists from Lancaster University and the University of Leeds have discovered that a compound found in green tea, currently being studied for its ability to reduce amyloid plaques in the brain in Alzheimer's disease, also breaks up and dissolves potentially dangerous protein plaques found in the blood vessels.
A quarter of intensive care patients are readmitted to hospital shortly after returning home and some of these readmissions are avoidable, research suggests.
High levels of carer stress, difficulty understanding health and social care packages and psychological trauma all contribute to high rates of return, the findings show.
Pinpointing the reasons for unplanned readmissions is key to developing care packages that support patients at home and could save vital funds, researchers say.
Researchers at the Feinstein Institute for Medical Research, USA have developed an index that identifies the risk for lupus based on the presence and amount of Immunoglobin G (IgG) and Immunoglobin M (IgM) antibodies and levels of C1q, a protein complex associated with protection from lupus, in blood serum. The findings are published in the open access journal Molecular Medicine.
When people are injured, how does the brain adapt the body's movements to help avoid pain? New research published in The Journal of Physiology investigates this question.
After an injury, our body will rapidly associate pain to a particular movement and modify which muscles we use accordingly. This new research shows that the message from motor brain areas toward a muscle is reduced if this muscle is responsible for producing a painful movement and increased if it the muscle counteracts that movement.
Scientists from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a way to use machine learning to dramatically accelerate the design of microbes that produce biofuel.
Prawns have personalities - and cautious crustaceans do better in the battle for food, new research shows.
Scientists from the University of Exeter studied rockpool prawns (Palaemon elegans) and found some were consistently shy, while others were bolder.
But this bravery may come at a cost - as the risk takers tended to do worse than other prawns when competing for food.
"We found that the shyer prawns were better at controlling a food source," said first author Daniel Maskrey, formerly of the University of Exeter but now at the University of Liverpool.
