This study builds on decades of work showing that the protein IL-24 attacks cancer broadly, and is the first to deliver the protein using T cells. This approach is in contrast to CAR-T cells, which are built to recognize proteins on the surface of cancer cells and haven't been successful against solid tumors. Mice with prostate cancer experienced shrinkage of the original tumor as well as distant metastases following treatment with IL-24 T cells. from Top Health News -- ScienceDaily https://ift.tt/3aTWUsz via IFTTT

Mitochondria are the energy suppliers of our body cells. These tiny cell components have their own genetic material, which triggers an inflammatory response when released into the interior of the cell. The reasons for the release are not yet known, but some cardiac and neurodegenerative diseases as well as the ageing process are linked to the mitochondrial genome. Researchers have investigated the reasons for the release of mitochondrial genetic material and found a direct link to cellular metabolism: when the cell's DNA building blocks are in short supply, mitochondria release their genetic material and trigger inflammation. The researchers hope to find new therapeutic approaches by influencing this metabolic pathway. from Top Health News -- ScienceDaily https://ift.tt/3ua8zLs via IFTTT

However, according to a new study, these mental defects can be successfully treated with lithium. from Top Health News -- ScienceDaily https://ift.tt/32Brwuy via IFTTT

In a worldwide study of 2,100 pregnant women, those who contracted COVID-19 during pregnancy were 20 times more likely to die than those who did not contract the virus. from Top Health News -- ScienceDaily https://ift.tt/3ekDz4O via IFTTT

Two new cases helped scientists confirm what many have come to suspect: that people can get infected by SARS-CoV-2 variants even after successful vaccination. The findings suggest continued testing may be needed to prevent future outbreaks in a post-vaccine world. from Top Health News -- ScienceDaily https://ift.tt/3nbatJ2 via IFTTT

Researchers showed that COVID-19 survivors -- including those not sick enough to be hospitalized -- have an increased risk of death in the six months following diagnosis with the virus. They also have catalogued the numerous diseases associated with COVID-19, providing a big-picture overview of the long-term complications of COVID-19 and revealing the massive burden this disease is likely to place on the world's population in the coming years. from Top Health News -- ScienceDaily https://ift.tt/3awCaqT via IFTTT

A new artificial intelligence (AI) method is helping researchers link immune cells to their targets and, for example, uncouple which white blood cells recognize SARS-CoV-2. The tool has broad applications in understanding the function of the immune system in infections, autoimmune disorders, and cancer. from Top Health News -- ScienceDaily https://ift.tt/3gwbxpG via IFTTT

Vigorous and rapid air exchanges might not always be a good thing when it comes to levels of coronavirus particles in a multiroom building, according to a new modeling study. Particle levels can spike in downstream rooms shortly after rapid ventilation. from Top Health News -- ScienceDaily https://ift.tt/32Ch5Xy via IFTTT

Research on how obesity impacts the diagnosis, management and outcomes of heart and blood vessel disease, heart failure and arrhythmias is summarized in a new statement. Waist circumference, an indicator of abdominal obesity, should be regularly measured as it is a potential warning sign of increased cardiovascular disease risk. Interventions that lead to weight loss improve risk factors yet may not always lead to improvement in coronary artery disease outcomes. from Top Health News -- ScienceDaily https://ift.tt/3axZG6L via IFTTT

Researchers discovered that enriching cell-free vaccine extracts with cellular membranes increased the yields of protein-based vaccines by five-fold, significantly broadening access to potentially lifesaving medicines. from Top Health News -- ScienceDaily https://ift.tt/3xgUfTw via IFTTT

When given a choice, most individuals with an average risk of colorectal cancer said they would prefer a stool-based screening test for colorectal cancer over colonoscopy, the method most often recommended by health care providers. from Top Health News -- ScienceDaily https://ift.tt/3nb98Ch via IFTTT

Higher mushroom consumption is associated with a lower risk of cancer, according to a new study. The systematic review and meta-analysis examined 17 cancer studies published from 1966 to 2020. Analyzing data from more than 19,500 cancer patients, researchers explored the relationship between mushroom consumption and cancer risk. from Top Health News -- ScienceDaily https://ift.tt/2Pdq2U6 via IFTTT

A new study is the first-ever to identify the genes for creativity in Homo sapiens that distinguish modern humans from chimpanzees and Neanderthals. The research identified 267 genes that are found only in modern humans and likely play an important role in the evolution of the behavioral characteristics that set apart Homo sapiens, including creativity, self-awareness, cooperativeness, and healthy longevity. from Top Health News -- ScienceDaily https://ift.tt/3tIfDio via IFTTT

Multi-resistant pathogens are a serious and increasing problem in today's medicine. Where antibiotics are ineffective, these bacteria can cause life-threatening infections. Researchers are currently developing nanoparticles that can be used to detect and kill multi-resistant pathogens that hide inside our body cells. The team published the study in the current issue of the journal Nanoscale. from Top Health News -- ScienceDaily https://ift.tt/3xeteQy via IFTTT

Much of common pharmaceutical development today is the product of laborious cycles of tweaking and optimization. In each drug, a carefully concocted formula of natural and synthetic enzymes and ingredients works together to catalyze a desired reaction. But in early development, much of the process is spent determining what quantities of each enzyme to use to ensure a reaction occurs at a specific speed. from Top Health News -- ScienceDaily https://ift.tt/3esFSTm via IFTTT
