AIDS and aging focus of research study

When the general public thinks of HIV, they do not think of a neurological disease, yet people living with HIV infection know they need to worry about their brain health. Untreated, HIV can cause severe dementia. Even with good control of the infection, a third or more of patients have […]

Laser technology provides detailed images of skin cancer

The first patients are expected to benefit from the new improved images in 2018. The project revolves around infrared light and finding the ideal wavelengths. Optical crystal fibres and laser technology. And shrinking a laser source that roughly fills two offices into shoebox-sized device. It draws on extensive knowledge of […]

Magnetic contrast agent behind clear MRI images

For decades, MRI scans have delivered stunningly beautiful images of the body’s anatomy. It is now possible to use MRI imaging at cellular level to observe cell metabolism. This is particularly useful in cancer treatment. With the help of a new technology, doctors may be able to determine on the […]

Diabetes results from a breakdown of epigenetic control

Diabetes affects more than 400 million individuals worldwide. In what is becoming a paradigm shift, researchers have begun to find that the disease may result in part through pancreatic beta cells losing their functional identity and shutting down their ability to release the blood sugar-lowering hormone, insulin. Researchers from the […]

Biomaterial Particles Educate Immune System to Accept Transplanted Islets

By instructing key immune system cells to accept transplanted insulin-producing islets, researchers have opened a potentially new pathway for treating type 1 diabetes. If the approach is ultimately successful in humans, it could allow type 1 diabetes to be treated without the long-term complications of immune system suppression. The technique, […]

Lipid molecules can be used for cancer growth

Tumour growth and spread rely on angiogenesis, a process of growing new blood vessels that supply the cancer cells with nutrients and hormones, including glucose (sugar). Treatment with antiangiogenic drugs reduces the number of blood vessels in the tumour as well as the blood glucose supply. Many such drugs have […]

The secret to longevity is in the microbiome and the gut

You are what you eat. Or so the saying goes. Science now tells us that we are what the bacteria living in our intestinal tract eat and this could have an influence on how well we age. Building on this, McGill University scientists fed fruit flies with a combination of […]

Study: Exercise mitigates genetic effects of obesity later in life

If you’re up there in age and feel like you can coast as a couch potato, you may want to reconsider. A new study suggests, for the first time in women over age 70, that working up a sweat can reduce the influence one’s genes have on obesity. “Our sample, […]

UVA researchers develop new technology to manage cancer pain

As cancer patients become increasingly ill toward the end of their lives, their pain often intensifies and increases in frequency. This is distressing not only to the patient, but also to the patient’s caregivers, often a spouse or partner. Effectively managing that pain with medications and other therapies is of […]

Scientists develop material that could regenerate dental enamel

Enamel, located on the outer part of our teeth, is the hardest tissue in the body and enables our teeth to function for a large part of our lifetime despite biting forces, exposure to acidic foods and drinks and extreme temperatures. This remarkable performance results from its highly organised structure. […]

Compounding Risk for Heart Disease and Stroke

Risk factors for heart disease and stroke appear to hasten the risk of cognitive decline in normal older individuals with evidence of very early Alzheimer’s disease-associated changes in the brain, according to a new study by Harvard Medical School investigators based at Massachusetts General Hospital. Vascular risk factors increase the […]

Poised Pluripotency

Stem cell researchers at Harvard Medical School and Boston Children’s Hospital have, for the first time, profiled a highly elusive kind of stem cell in the early embryo—a cell so fleeting that it makes its entrance and exit within a 12-hour span. They described this “poised pluripotent” cell in the […]

Defects in tissue trigger disease-like transformation of cells

Homeowners know that one little termite can lead to big problems: while termites are efficient at gnawing away at wood, they can do even more damage if the wood is already broken or has another defect. Mechanical engineers at Washington University in St. Louis have found the same effect in […]

Brain cancer vaccine effective in some patients

Most people with the deadly brain cancer glioblastoma die less than 18 months after diagnosis. But a multicenter clinical trial of a personalized vaccine that targets the aggressive cancer has indicated improved survival rates for such patients. The study appears in the Journal of Translational Medicine. The phase three clinical […]

Drugs that suppress immune system may protect against Parkinson’s

People who take drugs that suppress the immune system are less likely to develop Parkinson’s disease, according to a study from Washington University School of Medicine in St. Louis. The findings, published in Annals of Clinical and Translational Neurology, suggest that a person’s own immune system helps nudge him or […]
