Common HIV Drugs May Help Prevent Leading Cause of Vision Loss

Scientists have identified a group of drugs that may help stop a leading cause of vision loss after making an unexpected discovery that overturns a fundamental belief about DNA. The drugs, known as nucleoside reverse transcriptase inhibitors, or NRTIs, are commonly used to treat HIV. The new discovery suggests that […]

Immune system T cells to be trained to remove cancer

The immune system is an extremely complex organ system capable of fighting disease. However, it can also create disease because immune cells may—so to speak—run riot and start attacking the healthy cells of the body. This very delicate balance has always fascinated Professor Sine Reker Hadrup, and she has embarked […]

‘Five-minute rule’ holds true for cardiac death of organ donors: study

A Canadian-led research project has confirmed that it is safe to procure organs for transplant from dying patients once the heart has stopped for a full five minutes, in newly published findings in the New England Journal of Medicine. The researchers monitored blood pressure and electrocardiographic (ECG) waveforms in 631 dying patients following […]

Preventing seizures after brain injury could stave off dementia

Blocking seizures after a head injury could slow or prevent the onset of dementia, according to new research by University of Alberta biologists. “Traumatic brain injury is a major risk factor for dementia, but the reason this is the case has remained mysterious,” said Ted Allison, co-author and professor in the Department […]

Vaccines safe for majority of immunosuppressed children, find scientists

Both inactivated and live-attenuated vaccines generally produce an adequate immune response and are safe to use in children suffering from autoimmune diseases treated with all but the most potent immunosuppressants, according to a research review. The team examined 37 original articles: 25 studied the inactivated vaccines influenza; hepatitis A virus; […]

The underestimated mutation potential of retrogenes

A new study from scientists of the Max Planck Institute for Evolutionary Biology in Plön, Germany, and the Chinese Academy of Sciences in Beijing shows that the potential genetic burden of mutations arising from retrogenes is significantly greater than originally thought. Genetic information is stored in DNA and transcribed as […]

Suppression of Tyrosine Degradation Modestly Extends Life Span in Flies

There are a great many ways to influence cellular metabolism to modestly slow the pace of aging, but few of them are of lll that much interest from a practical point of view, as a basis for therapies that might meaningfully extend human life spans. If an approach involves improvements […]

Faster tracking of treatment responses

Biological sensors developed by MIT spinout Glympse Bio could help clinicians make decisions for individual patients. In the fight against severe diseases like cancer, patients often endure a discomforting, weekslong gap between when treatment begins and when doctors can tell if it’s working. The problem often stems from an inability […]

Deep Vision: Near-Infrared Imaging and Machine Learning Can Identify Hidden Tumors

Near-infrared hyperspectral imaging combined with machine learning can visualize tumors in deep tissue and covered by a mucosal layer, scientists show Gastrointestinal stromal tumors are tumors of the digestive tract that grow underneath the mucus layer covering our organs. Because they are deep inside the tissue, these “submucosal tumors” are […]

Unusual mutation causes defective sperm in boars

ETH researchers have found a gene mutation that causes the sperm of boars to immobilize. Their discovery will help pig breeders to exclude animals with this genetic defect from breeding in future. In pig farming, natural mating between a boar and a sow has become rare. It is much more […]

Study offers hope of new treatment for accelerated aging in children

Researchers from Karolinska Institutet and Gothenburg University have investigated a potential new drug target for the rare genetic disorder Hutchinson-Gilford progeria syndrome that causes accelerated aging in children. The findings in mice are published in the scientific journal eLife and may aid in the development of more effective treatments for […]
