Researchers use wristband sensors to detect how opioid users in emergency room reacted to dosages

There is merit in looking at the use of wearable biosensors to detect whether opioid users stay focused on their rehabilitation programs.

Metal ions released by implant wear can damage progenitors of bone-forming cells

In metal-on-metal pairings, both the shell and head of an implant consist of a cobalt-chromium-molybdenum alloy. The release of metal ions into the body has been reported as a result of implant wear. Bone loss (osteolysis) was observed in many cases.

Hops show promise in reducing breast cancer risk

Hops, the flower cones used in beer-making, are also found in dietary supplements designed to help treat post-menopausal symptoms and other conditions. Scientists are now investigating whether an extract from the plant could also help fend off breast cancer.

Highly efficient bacterial agent could improve treatment of Wilson disease

In the 'Journal of Clinical Investigation', scientists at the Helmholtz Zentrum München describe a small peptide that very efficiently binds excess copper from liver cells. This molecule comes from a bacterium's bag of tricks and could be suitable for treating Wilson disease.

E-cigarette use modifies gene expression important for upper airway immune defense

When we smoke cigarettes, dozens of genes important for immune defense are altered in the epithelial cells that line the respiratory tract. Several of these changes likely increase the risk of bacterial infections, viruses, and inflammation.

Scientists study fundamentals of tumour surveillance by immune system in mice models

The body's defences detect and eliminate not only pathogens but also tumour cells. Natural killer cells (NK-Cells) are specifically activated by chemical messengers, the Cytokines, to seek and destroy tumour cells.

Endocrine Society members advocate science-based policies to address danger of EDCs

To protect human health, Endocrine Society members called on the European Commission to adopt science-based policies for regulating endocrine-disrupting chemicals in an opinion piece published today in The Lancet Diabetes & Endocrinology.

Tackling Healthcare Challenges in a Changing World: an Interview with Professor Jeremy Nicholson

As individuals and as populations our risks of getting diseases are determined partly genetically and partly from the environment that we live in. An important part of that environment that mediates between the outside world and the inside world of our bodies is the microbiome.

Metabolite of oral DMF drug for multiple sclerosis appears to slow onset of Parkinson's disease

The metabolite of a drug that is helping patients battle multiple sclerosis appears to significantly slow the onset of Parkinson's disease, researchers say.

New IRAP inhibitors may hold promise for improving cognitive functions in animal models

Researchers have discovered three new inhibitors of insulin-regulated aminopeptidase (IRAP), compounds shown to improve cognitive functions in animal models of human disorders.

Cell phone radiation exposure may lead to increased rates of rare cancers

According to new report from Microwave News, the U.S. National Toxicology Program has found increased rates of rare cancers of the heart and brain in animals exposed to cell phone radiation in a long-awaited multi-million dollar two-year study.

Nutrition, safety tips for grilling season

Cooking meat, including beef, pork, fish, or poultry, with high-temperature methods such as pan frying or grilling directly over an open flame can increase exposure to chemicals that can cause changes in DNA that may increase the risk of cancer, according to the National Cancer Institute.

Scientists find ketamine as effective sedative for treating highly-agitated patients prior to hospitalisation

Scientists have shown that ketamine is far more effective than the more commonly used haloperidol for treating highly-agitated patients prior to hospitalisation.

Conventional repeated radiation treatments may offer no major benefit to brain tumor patients

A new study shows that repeated radiation therapy used to target tumors in the brain may not be as safe to healthy brain cells as previously assumed.

Novel therapeutic approach to treat leukaemia patients

Cancer cells have an abnormal cell division and survival machinery - they grow faster than they die. For their permanent development, they produce an excess of growth factors and nutrients and block the body's own safety mechanisms.

International study shows direct link between continued marijuana use during pregnancy and pre-term birth

International research led by the University of Adelaide has for the first time shown a direct link between continued marijuana use during pregnancy and pre-term birth.

Researchers develop novel ss-siRNAs to turn off disease-related genes

Combining the therapeutic potential and advantages of existing oligonucleotide-based approaches to turn off disease-related genes, a type of single-stranded silencing RNAs (ss-siRNAs) has shown significantly improved potency and activity.

High-throughput screening can help detect multiple compounds with potent antimicrobial activity

A new study in which researchers rapidly screened more than 11,000 bioactive molecules for activity against an antibiotic-resistant strain of Klebsiella pneumoniae bacteria identified multiple compounds with potent antimicrobial activity.

UCLA study shows anti-nausea drug does not increase risk of birth defects

Women suffering from extreme morning sickness often take Zofran (ondansetron) to combat their debilitating nausea and vomiting. However, two studies have found that the drug may increase risk of heart defects and cleft palate in children exposed in utero.
