A type of fatty liver disease that commonly affects patients with HIV can be safely treated with vitamin E, a McGill-led study has found. Nonalcoholic steatohepatitis (NASH) is a severe form of nonalcoholic fatty liver disease (NAFLD) and is characterized by liver inflammation and cell damage. It is a potentially […]

Crohn's disease is a chronic inflammatory bowel disease (IBD). Several previous studies have reported an increased risk of colorectal cancer in patients with Crohn's disease, but these studies are older and have often shown uncertain risk estimates. Now researchers from Karolinska Institutet, Örebro University and Aarhus University, Denmark, published the […]

Experts have been unable to explain why cells from bacteria to humans leak essential chemicals necessary for growth into their environment. New mathematical models reveal that leaking metabolites — substances involved in the chemical processes to sustain life with the production of complex molecules and energy — may provide cells […]

There are more than 100 different autoimmune diseases. But what unites them all is that they arise from an individual’s own cells – rare and mysterious immune cells that target not external viruses and bacteria but the body’s own healthy organs and tissues. For the first time, a team led […]

Biologists have discovered a way to stop cells from one of the most aggressive types of breast cancer spreading in the lab. The study points towards new avenues of research to combat the devastating disease. The results of the study of Triple-Negative Breast Cancer by the team from the Universities […]

After 12 million measurements, new drug targets emerge A study published Feb. 13 in Cell provides an unprecedented look at the dozens of molecular steps that occur to bring about endometrial cancer, commonly known as uterine cancer. The study offers insights about how physicians might be able to better identify […]

In the United States, the medical community has made great strides in preventing and controlling cervical cancer. Screening can effectively detect the disease in its earliest, pre-cancerous stages, while the HPV vaccine is highly effective at preventing cervical cancer. That combination has led to a 50% drop in cervical cancer […]

How to detect diseases at the earliest stages of development? This is the problem raised by most scientists and physicians, focusing on new biomarkers, such a microRNAs. Indeed, a growing number of publications link microRNA levels inside biological liquids to several diseases including some cancers. However, these microRNA molecules are […]

There is a growing consensus that the gut microbiome is involved in many aspects of physical and mental health, including the onset of Parkinson's disease, multiple sclerosis, and even some behaviors. The microbiota of the small intestine, in particular, are likely to have important effects on human health because most nutrients and drugs […]

In the largest study of skin cancer rates among gay, lesbian or bisexual individuals, investigators from Brigham and Women’s Hospital report important differences in skin cancer prevalence among sexual minorities. Rates of skin cancer were higher among gay and bisexual men compared to heterosexual men but lower among bisexual women than heterosexual […]

A Caenorhabditis elegans worm squirms its way through a compost heap, sensory neurons in its nose helping it navigate oxygen and carbon dioxide cues as it searches for food. The lab of Harvard Medical School geneticist Max Heiman studies these neurons to illuminate nervous system development and uncover clues about how things go awry […]

Missing a single ophthalmology appointment over a two-year period was associated with decreased visual acuity for patients with macular degeneration — a leading cause of permanent vision loss in the elderly — according to a new Penn Medicine study. The findings, published in JAMA Ophthalmology, suggest that more attention should be […]
