A type of immune cell could hold a key to preventing scar tissue buildup in wounds

A study by University of Arizona researchers reveals a previously unknown population of circulating immune cells that play a critical role in fibrosis, the buildup of scar tissue. Blocking signals from these cells during wound healing can reduce scar tissue formation and promote normal healing.

Enantioselective maternal transfer of pesticide metabolite and its thyroid effects

A new study reveals that the S-enantiomer of o,p'-DDD pesticide metabolite is more toxic to zebrafish larvae and has severe consequences for their development. The research found that maternal transfer was highly efficient, with the S-enantiomer accumulating in higher levels than its mirror-image R-form.

How plants search for nutrients

Researchers at Technical University of Munich found that boron-efficient plants can grow well with little boron by using long, lateral roots for nutrient uptake. The team identified genes responsible for boron utilization and uptake in roots and shoots, which could help breed more climate-resilient crops.

Metabolic roots of memory loss

Researchers identified biological markers of inflammation, liver stress, and early damage to brain cells in young adults with obesity. Low blood levels of choline, essential for liver health and long-term brain function, were also found. These findings suggest that metabolic stress and inflammation may begin far earlier than expected.

Comparison of pre-procedure lignocaine spray vs. spray-as-you-go for topical airway anesthesia in flexible bronchoscopy

This study compared pre-procedure lignocaine spray (PPL) and spray-as-you-go (SAYG) airway anesthesia in fiberoptic bronchoscopy. The results showed no significant differences in patient-reported pain, discomfort, coughing, or procedure duration between the two groups. However, operator comfort was slightly higher with the PPL protocol.
