Trial identifies 4 grams a day as the tested safe level for L-tyrosine in healthy men

A randomized, crossover trial in healthy adult men found that 4 weeks of L-tyrosine supplementation at doses up to 4 g/day did not cause clinically meaningful changes in safety markers, diet, blood pressure, or body measures. The highest tested dose, 4 g/day, was identified as the no-observed-adverse-effect level under the study’s four-week conditions, although broader and longer-term studies are still needed.

AI-created miniproteins show promise for targeting hard-to-treat diseases

G protein-coupled receptors, or GPCRs, sit in the plasma membrane, the boundary that defines the inside and outside of a living cell. They communicate with nearly every physiological process in our bodies - from the ability to see and smell, to sensing of adrenaline, insulin, nutrients and medicines.

Discontinuing beta-blockers after heart attack found to be safe for low-risk patients

Among stable, relatively low-risk patients who had previously suffered a heart attack, discontinuing beta-blockers after at least one year was found to be non-inferior, or comparable, to continuing beta-blockers in terms of death, another heart attack or hospitalization for heart failure, according to a study presented at the American College of Cardiology's Annual Scientific Session.

Systematic review identifies stress-induced biological triggers in oncology

Stress is a constant companion in the oncologist's office. It appears at the time of diagnosis, increases with each stage of treatment, and often does not resolve even after therapy formally ends. It accompanies therapeutic decisions, waiting for test results, fear of recurrence, and changes in daily functioning. Studies show that chronic stress can trigger biological processes that promote disease progression and weaken the body's defenses.
