Researchers at the University of Maryland, Baltimore County (UMBC) have discovered a key step that enteroviruses use to replicate inside human cells. The survey results are nature communicationsexplains how viruses that cause diseases such as polio, encephalitis, myocarditis, and even the common cold control cellular machinery to copy themselves. Scientists say the discovery could ultimately help researchers develop a new generation of antiviral drugs that can target many enteroviruses at once. The research was led by Deepak Koirala, associate professor of chemistry and biochemistry at UMBC and recent Ph.D. Graduate of Nava Krishna Das. Their research helps answer long-standing questions…

Scientists have identified a new weakness in harmful “zombie-like” cells, which could open the door to better cancer treatments and treatments for age-related diseases. These cells, known as senescent cells, survive in vulnerable conditions by producing large amounts of protective proteins that prevent cell death. Researchers from the MRC Institute of Medical Sciences (LMS) and Imperial College London have discovered that removing this protection can force cells to self-destruct, offering a promising new treatment strategy. The findings suggest that this approach could be used in combination with chemotherapy and other existing cancer treatments to improve patient outcomes. Why aging “zombie…

Monoclonal antibodies can block key immune-related proteins that cause widespread brain cell damage in Parkinson’s disease (PD). The protein, called glycoprotein non-metastatic melanoma B (GPNMB), may be part of a promising strategy to develop treatments that slow disease progression in its early stages, according to a new study published today, December 11, 2018. neuron, By researchers at the Perelman School of Medicine at the University of Pennsylvania. Many people with Parkinson’s disease are diagnosed in the early stages, when symptoms are relatively mild, and there is currently no treatment to slow the disease’s progression. These early results are a…

Tough caring responsibilities reduce brain function in people over 50, but light caring responsibilities may actually benefit mental performance in middle age, new research from UCL has found. Regarding this research, age and aging, The researchers used data from the UK Longitudinal Study of Aging (ELSA) from 2004-05 to 2021-23. ELSA is a long-term, nationally representative survey led by UCL that collects a wide range of information from around 20,000 people aged 50 and over in the UK who are re-interviewed every two years. The survey consists of 12 topics and includes information about participants’ caregiving responsibilities and physical and…

Mothers who work in jobs where they are frequently exposed to toxic chemicals or experience high levels of stress are more likely to have children with autism spectrum disorder (ASD), suggests an original study published online in the journal Children’s Health. Occupational and environmental medicine. ASD is a lifelong neurodevelopmental condition characterized by impairments in social communication and restricted or repetitive behaviors. Previous research has shown a potential association between some maternal occupations and children’s ASD, but the results have been inconsistent. However, these previous studies tended to use small study samples or rely on self-reported exposure data. They also…

New multi-site study presented at natural mental health It has been found that using cannabis and tobacco together increases the risk of developing psychiatric disorders such as schizophrenia, which are considered high-risk. Researchers led by Heather Ward, M.D., assistant professor of psychiatry and behavioral sciences and director of neuromodulation research at Vanderbilt Health, analyzed data from more than 1,000 participants in the North American Progenitor Longitudinal Study, which tracks individuals at “clinical high risk” for psychosis. These people often experience mild or early symptoms but have not yet developed a full-blown psychotic disorder. The prevalence of cannabis and tobacco…

UBC Okanagan researchers have uncovered the process plants use to produce mitraphylline. Mitraphylline is a rare natural compound that has received attention for its possible cancer-fighting properties. Mitraphylline belongs to a unique class of phytochemicals known as spirooxindole alkaloids. These molecules are known for their unusual twisted ring structures and potent biological effects, including anti-inflammatory and antitumor activities. Scientists have been studying these compounds for years, but the exact molecular steps plants use to produce them have remained unclear. Groundbreaking discoveries in phytochemistry The mystery began to unravel in 2023, when Dr. Tutui Dunn’s team at UBC Okanagan’s Irving K.…

A team led by USC stem cell scientist Dr. Zhongwei Li has created some of the most complex and mature laboratory-cultured kidney models to date. With the support of a three-year grant from the California Institute for Regenerative Medicine (CIRM), Lee and colleagues are now mapping the properties, structure, and function of these mini-kidney structures, known as human synthetic kidney organoids (hSKOs), to show how they can advance disease research. hSKO, small organ-like structures grown from human stem cells, could ultimately contribute to efforts to build replacement organs for transplant patients, while also providing a more immediate and powerful way…

Researchers at Rice University and the University of Texas MD Anderson Cancer Center have developed a miniature imaging device powered by artificial intelligence that could change the way clinicians detect cancer. The technology aims to bring high-resolution, real-time diagnostics directly to the point of care and was recently described in a paper published in the Proceedings of the National Academy of Sciences. The device, called PrecisionView, is a handheld endoscope that overcomes the limitations of medical image processing by combining advanced optical technology and deep learning. This system allows clinicians to visualize both intracellular structures and underlying blood vessels over…

Scientists at the Icahn School of Medicine at Mount Sinai have successfully reversed aging in hematopoietic stem cells in mice by repairing defects in structures known as lysosomes. The survey results are cell stem cellspoint out that lysosome dysfunction and overactivity are the main causes of stem cell aging, and show that restoring proper lysosome activity can rejuvenate old stem cells and improve their ability to regenerate blood and immune cells. Lysosomes act as internal recycling centers of cells. They break down proteins, nucleic acids, carbohydrates, and lipids, helping cells process waste products and recycle materials needed for important biological…
