Scarred liver tissue creates fertile ground for cancer development

Over 80% of hepatocellular carcinoma (HCC) – the third-leading cause of cancer deaths globally – emerges from advanced liver fibrosis or cirrhosis. A comprehensive review in Hepatology International synthesizes decades of research to reveal how scarred liver tissue becomes a breeding ground for cancer.

Metformin lowers blood sugar by acting on brain pathways

Although metformin has been the go-to medication to manage type 2 diabetes for more than 60 years, researchers still do not have a complete picture of how it works.

Can stacking creatine and β-alanine give you extra gains? Here’s what science says

Co-supplementation with creatine and β-alanine may enhance high-intensity exercise performance, especially in repeated short bursts. However, it offers no additional benefit over creatine alone for maximal strength, aerobic capacity, or body composition.

Why Spirulina could be a helpful natural option for lowering blood pressure

A comprehensive meta-analysis found that consuming whole microalgae, especially Spirulina, can significantly lower blood pressure, particularly in adults with elevated levels. No significant effects were observed for macroalgae or algae extracts.

Brisk walking for just 15 minutes a day cuts death risk in low-income adults, study shows

Fast walking for as little as 15 minutes per day was linked to a nearly 20% reduction in mortality among predominantly Black and low-income American adults. Slow walking showed minimal benefit, but prolonged slow walking reduced the risk of death from ischemic heart disease.

E-scooter riders are three times more likely than cyclists to end up in hospital, study shows

Stand-up electric scooter riders in Helsinki are over three times more likely than cyclists to sustain injuries requiring emergency care, with head trauma and alcohol use significantly more common in scooter crashes. Helmet use among scooter riders remains exceptionally low.

CPADS enables comprehensive analysis of drug resistance across 44 cancer types

CPADS integrates data from the Gene Expression Omnibus (GEO), The Cancer Genome Atlas (TCGA), and the Genomics of Drug Sensitivity in Cancer (GDSC) databases, encompassing over 29,000 samples across 44 cancer types and involving 288 drugs. It provides five main analysis modules: differential expression analysis, correlation analysis, pathway analysis, drug analysis, and gene perturbation analysis.

Infant brain activity shows faster maturation after general anesthesia

New research published today in Proceedings of the National Academy of Sciences (PNAS) finds that prolonged and/or repeated exposure to gamma-aminobutyric acid (GABA) anesthetic agents (sevoflurane, propofol) for infants in the first two months of life resulted in an accelerated maturation of brain electrical activity patterns evoked by visual stimuli when recorded at 2-5 months of age, compared to infants who did not have early general anesthesia exposure.

Thalamic feedback pathway found to tune sensory perception

The cerebral cortex processes sensory information via a complex network of neural connections. How are these signals modulated to refine perception? A team from the University of Geneva (UNIGE) has identified a mechanism by which certain thalamic projections target neurons and modify their excitability.

Respiratory infections can reactivate dormant breast cancer cells

Researchers at the University of Colorado Anschutz Medical Campus, Montefiore Einstein Comprehensive Cancer Center (MECCC), and Utrecht University have found the first direct evidence that common respiratory infections, including COVID-19 and influenza, can awaken dormant breast cancer cells that have spread to the lungs, setting the stage for new metastatic tumors.

New insights reveal how Candida albicans settle and persist in the gut

About 80% of people have the fungus Candida albicans in their gut. Although most of the time it persists unnoticed for years causing no health problems, C. albicans can turn into a dangerous microbe that causes serious diseases in many organs, including the urinary tract, lungs and brain.

Intratumoral microbial metabolites shape the tumor microenvironment and impact immunotherapy

The tumor microenvironment (TME) represents a highly complex system that encompasses cellular components (such as cancer cells, stromal cells, and immune cells) and non-cellular components (such as blood vessels and signaling molecules).
