Charcoal Nano-materials Fight Superoxide-Induced Disease, May Aid Treatment of COVID-19
Artificial enzymes made of treated charcoal could have the power to curtail damaging levels of superoxides, toxic radical oxygen ions that appear at high concentrations after an injury.
Breakthrough Discovery to Transform Prostate Cancer Treatment
A novel formulation of the prostate cancer drug abiraterone acetate - currently marketed as Zytiga - will dramatically improve the quality of life for people suffering from prostate cancer, as pre-clinical trials show the new formulation improves the drug's effectiveness by 40 per cent.
Viruses Steal Genetic Code to Create New Human-Virus Genes
Now researchers have shown that a large group of viruses, including the influenza viruses and other serious pathogens, steal genetic signals from their hosts to expand their own genomes.
Antihistamines May Slow Early Progression of Huntington's Disease
Scientists have described a potential new therapeutic strategy for slowing down early-stage Huntington's disease.
Aspirin Linked to Reduction of Cancers of the Digestive Tract
The largest and most comprehensive analysis to date of the link between aspirin and cancers of the digestive tract has shown that it is associated not only with a significant reduction in the risk of developing bowel cancer but also of several other cancers that almost invariably fatal, such as pancreatic and liver cancers.
Proteins May Block Lethal Cytokine Storms Seen in COVID-19 Patients
A team of researchers has developed specialized antibody-like receptor proteins that they believe could soak up the excess cytokines produced during a cytokine storm. This excessive immune response, sometimes seen in Covid-19 patients, can be fatal.
Emotional Stress Remodels Neurons to Alter Brain Function
Working in a mouse model, researchers report that a single stressful event produced quick and long-lasting changes in astrocytes, the brain cells that clean up neurotransmitters after they've communicated information between nerve cells.
Researchers Identify New Marker That Predicts Likely Spread of Lung Cancer
Non-small cell lung cancer (NSCLC) is the most commonly diagnosed cancer, and the leading cause of cancer death worldwide. More than half of NSCLC patients die after developing metastases. There are no tests currently that would allow doctors to identify patients where more aggressive therapy could reduce mortality. Researchers at Tulane University have identified a protein on tumor-derived extracellular vesicles that indicates if a NSCLC tumor is likely to metastasize, according to a new study in Science Advances.
Protein in Eye Protects Lens From Damaging Oxidation
The lens of the human eye comprises a highly concentrated protein solution, which lends the lens its great refractive power. Protective proteins prevent these proteins from clumping together throughout a lifetime. A team of scientists from the Technical University of Munich (TUM) has now uncovered the precise structure of the alpha-A-crystallin protein and, in the process, discovered an important additional function.
Study Reveals How Insulin-Like Hormone Relaxin Reverses Cardiovascular Disease
As a healthy heart ages, it becomes more susceptible to cardiovascular diseases. Though researchers have discovered that relaxin, an insulin-like hormone, suppresses atrial fibrillation (AF), inflammation, and fibrosis in aged rats, the underlying mechanisms of these benefits are still unknown. Researchers discuss how relaxin interacts with the body's signaling processes to produce a fundamental mechanism that may have great therapeutic potential.
