Cannabis-derived nanovesicles showed early antitumor potential in mice

Researchers developed a Cannabis sativa hairy root culture system that produced stable plant-derived nanovesicles capable of promoting dendritic cell maturation and activating T-cell responses through TLR2- and TLR4-associated signaling. Oral administration also restored selected immune responses in immunosuppressed mice and suppressed tumor growth in an E.G7 lymphoma model, providing preliminary evidence for their immunomodulatory and antitumor potential.

Why frailty and heart health may be more closely connected than we thought

A narrative review proposes cardiovascular frailty as a distinct phenotype that brings together blood pressure regulation, vascular aging, oxi-inflammaging, and clinical frailty deficits. The authors argue that a validated cardiovascular frailty index could support earlier detection and personalized care, although longitudinal studies are needed before the concept can be used clinically.

What children eat may leave a measurable signature in their blood

Researchers analyzed 236 blood metabolites in 421 children to examine metabolic signatures associated with three dietary patterns characterized by core foods, animal protein sources, or poor-quality fats and sugars. The results identified distinct, biologically plausible metabolite patterns across dietary exposures, although most individual associations did not survive multiple-testing correction and require validation in independent cohorts.

Study raises questions about AI's role in decision support for ethically sensitive situations

Artificial intelligence (AI) models prioritize starkly different attributes than humans when making high-stakes decisions, and they don't express indecision like humans do, according to a new study led by Penn State researchers, raising questions about the role of AI in decision support for ethically sensitive situations like medical decisions.

Natural anti-NMDAR1 antibody may protect the brain following traumatic brain injury

Every year, an estimated 20 million people worldwide sustain a concussion or other traumatic brain injury (TBI), which leads to a two- to four-fold increase in the risk of depression, anxiety and post-traumatic stress disorder (PTSD).
