What is the perception of patients regarding their doctors using marijuana? This is what a recent study published in the Journal of Hand Surgery Global Online hopes to address as a team of researchers investigated how patient perceptions regarding their doctors using marijuana outside of work, especially since marijuana continues to be categorized as a Schedule 1 substance per the U.S. Drug Enforcement Agency. This study has the potential to help…

Millions of kilometres of rivers around the world are carrying antibiotic pollution at levels high enough to promote drug resistance and harm aquatic life, a McGill University-led study warns.
Published in PNAS Nexus, the study is the first to estimate the scale of global river contamination from human antibiotics use. Researchers calculated that about 8,500 tonnes of antibiotics — nearly one-third of what people consume annually — end up in river systems around the world each year even…

By creating a more true-to-life representation of DNA’s environment, researchers at Northwestern University have discovered that strand separation — the essential process a “resting” double helix undergoes before it can initiate replication or make repairs — may take more mechanical force than the field previously believed.
Most biochemistry labs that study DNA isolate it within a water-based solution that allows scientists to manipulate DNA without interacting with other molecules. They…

A research team led by the School of Public Health in the LKS Faculty of Medicine, the University of Hong Kong (HKUMed), in collaboration with the Centre for Immunology & Infection (C2i), has achieved a significant breakthrough in developing broadly protective, live-attenuated influenza vaccines (LAIV). These innovative LAIV platforms offer potential to develop universal influenza vaccines that induce a more robust immune response against various virus subtypes, including both human and…

Modern HIV medicine is based on a common genetic mutation. Now, researchers have traced where and when the mutation arose — and how it protected our ancestors from ancient diseases.
What do a millennia-old human from the Black Sea region and modern HIV medicine have in common?
Quite a lot, it turns out, according to new research from the University of Copenhagen.
18-25 percent of the Danish population carries a genetic mutation that can make them resistant or even immune to HIV. This…

Researchers at the Tohoku University Graduate School of Medicine have uncovered a key primary step in the hepatic ERK pathway that leads to increased insulin production. While their previous work focused on aspects of the signaling pathway from the liver to the pancreas, this current study shows an even earlier step that begins in the colon when it is inflamed — triggered by obesity. The present study revealed a novel role the gastrointestinal tract plays in regulating glucose homeostasis.

Pregnant women with metabolic dysfunction-associated steatotic liver disease (MASLD) have an increased risk of giving birth prematurely and the risk increase cannot be explained by obesity, according to a new study from Karolinska Institutet published in the journal eClinicalMedicine.
It is estimated that one in five people in Sweden has MASLD, previously called non-alcoholic fatty liver disease, and globally it may be as many as three out of ten. Common risk factors are metabolic disorders…

A special enzyme — the so-called ubiquitin-selective unfoldase p97/VCP — is one of the main players when cells remove malformed or excess proteins from their interior. This is the central finding of a new study, the results of which have now been published in the journal Nature Communications.
The new findings form the basis for a better understanding of numerous pathological processes. They clearly show that blocking this enzyme causes proteins to fold incorrectly and form aggregates,…

Tempted to skip the floss? Your heart might thank you if you don’t. A new study from Hiroshima University (HU) finds that the gum disease bacterium Porphyromonas gingivalis (P. gingivalis) can slip into the bloodstream and infiltrate the heart. There, it quietly drives scar tissue buildup — known as fibrosis — distorting the heart’s architecture, interfering with electrical signals, and raising the risk of atrial fibrillation (AFib).
Clinicians have long noticed that people with…
