Arginine slows amyloid buildup and improves brain outcomes in Alzheimer’s disease models

Arginine reduced amyloid beta aggregation in vitro and in both Drosophila and AppNL-G-F mouse models of Alzheimer’s disease, leading to fewer dense-core plaques and improved behavior. The study provides preclinical evidence that oral arginine may modulate amyloid pathology, although high dosing requirements and model limitations constrain human translation.

Researchers identify the key habits that help adults eat more slowly

Eating slowly and chewing well in Japanese adults were strongly associated with savoring food and avoiding eating with a full mouth, with oral health playing an important supporting role. These behaviours varied across age and gender groups, highlighting cultural eating practices and dental factors that shape how people eat across adulthood.

Study clarifies why most colic isn’t caused by cow’s milk allergy

Cow’s milk allergy rarely causes infant colic on its own, and most excessively crying infants do not have underlying allergy. A short elimination–and–rechallenge trial may help confirm CMA only when colic coexists with other allergic features.

New clinical trial shows promise for shorter TB treatment

New clinical trial results presented by TB Alliance at the Union World Conference on Lung Health show that the novel antibiotic candidate sorfequiline (TBAJ-876), a next-generation diarylquinoline, has the potential to improve tuberculosis (TB) treatment when combined with pretomanid and linezolid in a treatment regimen known as "SPaL."

Oral semaglutide delivers real-world drops in blood sugar and weight in diabetes trial

Oral semaglutide delivered meaningful reductions in HbA1c and body weight among GLP-1RA-naïve adults with type 2 diabetes in a Dutch real-world cohort. Lipid levels and blood pressure showed only small changes, reflecting modest cardiometabolic effects outside glucose and weight control.

New insights into periodontitis reveal gender-specific inflammatory mechanisms

A study out of the University of North Carolina at Chapel Hill has unveiled new insights into the inflammatory processes behind periodontitis, a common and debilitating gum disease. Research conducted by UNC Adams School of Dentistry's Julie Marchesan, DDS, PhD, and UNC School of Medicine's Jenny Y. Ting, PhD, found that a part of the immune system called the inflammasome plays a key role in disease development, and that blocking this system prevents bone resorption only in males.
