Hormonal shifts can cause vaginal itching before a period. Sometimes, however, the itching might be due to an infection, in which case the timing of the itchiness is purely coincidental. Some common reasons a person might experience vaginal itching around their period include a yeast infection, bacterial vaginosis (BV), vaginal dryness, inflammation, and the use...
Cocaine and alcohol can produce dangerous side effects when people combine them. In some cases, the effects of cocaine and alcohol can cause life threatening complications. In this article, we look at the effects of combining cocaine and alcohol. We also explain what precautions to take and the treatment options. What is cocaine? Consuming cocaine...
Disrupted nightly sleep and clogged arteries tend to sneak up on us as we age. And while both disorders may seem unrelated, a new study from the University of California, Berkeley, helps explain why they are, in fact, pathologically intertwined. UC Berkeley sleep scientists have begun to reveal what it is about fragmented nightly sleep...
by Alan Mozes, Healthday Reporter The concern comes as 16- to 18-year-olds have emerged as one of the fastest-growing groups of blood donors nationwide. But this study of nearly 31,000 teens who gave blood more than once between 2016 and 2018 found that roughly one in 10 were already iron-deficient when they donated for the...
Going without sleep for too long kills animals but scientists haven’t known why. Newly published work suggests that the answer lies in an unexpected part of the body. Inside a series of tubes in a bright, warm room at Harvard Medical School, hundreds of fruit flies are staying up late. It has been days since...
By Sally Robertson, B.Sc. A group of over 120 researchers from various institutions across Europe has performed the first genome-wide association study to reveal host genetic factors that may contribute to respiratory failure in cases of coronavirus disease 209 (COVID-19). The authors say the genetic variants they have identified could help guide further research into...
Canadian scientists have achieved a first in the study of telomerase, an essential enzyme implicated in aging and cancer. In today’s edition of the prestigious journal Molecular Cell, scientists from Université de Montréal used advanced microscopy techniques to see single molecules of telomerase in living cells. A flaw in the replication of chromosomes means that...
A game-changing technique for imaging molecules known as cryo-electron microscopy has produced its sharpest pictures yet — and, for the first time, discerned individual atoms in a protein. By achieving atomic resolution using cryogenic-electron microscopy (cryo-EM), researchers will be able to understand, in unprecedented detail, the workings of proteins that cannot easily be examined by...
Chemical compound restores tetracycline’s effectiveness by blocking bacterial resistance. The latest generation of tetracyclines — a class of powerful, first-line antibiotics — was designed to thwart the two most common ways bacteria resist such drugs. But a new study from researchers at Washington University in St. Louis and the National Institutes of Health (NIH) has...
Haima Therapeutics has executed an exclusive license agreement with Case Western Reserve University to research, develop, and market artificial platelet technologies to treat patients with various bleeding disorders. The core technologies were developed in the laboratory of Professor Anirban Sen Gupta, a pioneering researcher in platelet-inspired technologies in the Department of Biomedical Engineering at the...
