Chemical engineers from the USC Viterbi School of Engineering have unlocked a fatal vulnerability in many cancer cells—sugar inflexibility. Like any cells in the body, cancer cells need sugar ­– namely glucose – to fuel cell proliferation and growth. Cancer cells in particular metabolize glucose at a much higher rate […]

New images of an enzyme in action as it interacts with the chromosome could provide important insight into how cells — including cancer cells — regulate their genes. The enzyme, LSD1, can “turn off” gene expression by removing chemical flags (methyl groups) from the nucleosome — tightly packed units of […]

One woman shares her experience with the Ross procedure, an aortic valve replacement surgery performed by only a few cardiac surgeons in the country. As a teacher at Madonna University in Livonia, Michigan, Anne McLeod, R.N., D.N.P., was able to let her nursing students hear the sound of a heart […]

A major U.S. study reveals large gaps between urban and rural patients in quality of care received after a stroke and rates of survival. In more rural areas, the ability of hospitals to deliver advanced stroke care is lower and mortality rates substantially higher, the research shows. The analysis, involving […]

The results of this work are presented in the medical journal Blood Advances published by the American Society of Hematology. Routine neonatal screening, although not yet available in Quebec, has led to an increase in the incidence of patients diagnosed with SCID in North America in recent years. This syndrome, a […]

The Recombinant Antibody Network (RAN), a consortium comprising research groups from UC San Francisco, the University of Chicago, and the University of Toronto, has entered into a second research collaboration with Celgene that aims to create and develop high-performance recombinant antibodies against diverse targets in human cells. The first RAN collaboration […]

Yale clinicians report promising results after treating COVID-19 patients at Yale-New Haven Hospital (YNHH) with a drug that reduces hyper inflammation in cancer patients undergoing immunotherapy. The team initially gave the drug, tocilizumab, to the most severely ill COVID-19 patients — specifically, those experiencing a dangerous immune response known as […]

Metastasis accounts for approximately 90 percent of mortality in breast cancer patients. During the last few decades, there has been significant progress in understanding genetic, molecular and signaling mechanisms underpinning cancer cell migration. Biologists from Lawrence Livermore National Laboratory (LLNL) found another mechanism that affects the maintenance and expansion of malignant cells: […]

Having bad teeth hurts your mouth, blood vessels and blood itself, and even your brain. Many people have fear of dentists. But did you know there are dentists for phobic patients too? Visiting an oral health specialist may also have another – often hidden but positive consequence – a potential […]

Professor Vadim Fraifeld, the head of the Laboratory for Biology of Aging, together with his team announced new results from the study in which they have investigated the anti-aging effects of lower body temperature in mice. According to V. Fraifeld, lowering the temperature of biological systems and tissues is currently […]

Each year in Australia, it is estimated 2,400 babies are affected with congenital heart disease. People with complex and severe congenital heart disease require specialist treatment throughout their life. Understanding congenital heart disease and the factors that impact the maternal environment prior to and during pregnancy will be the focus […]

Researchers have created a device that can integrate and interact with neuron-like cells. This could be an early step toward an artificial synapse for use in brain-computer interfaces. In 2017, Stanford University researchers presented a new device that mimics the brain’s efficient and low-energy neural learning process. It was an […]

To defend the body, the immune system makes proteins known as antibodies that latch onto the perceived threat, be it HIV, the new coronavirus or, as is the case in autoimmune disease, part of the body itself. In a new proof-of-concept study in ACS Sensors, researchers describe a new system for […]

The risk of early-onset neonatal bacterial sepsis increases with maternal obesity, according to a new study of the University of Michigan and the Karolinska Institute in Sweden.
