Approach: human outcome. Palette: natural.

Close, low-angle shot of an older adult's bare lower leg and bare feet resting on crisp white hospital bed linen, with a soft, out-of-focus window in the background. The camera sits at mattress level and looks along the calf toward the ankle. Face is not visible. A small ultrasound probe coated in clear gel presses against the back of the knee. The operator's gloved hand enters from the frame edge. Soft overcast daylight from the window gives skin tones a warm, realistic look. Around the bed, a sprig of fresh rosemary and a few purple-green ashwagandha leaves sit on a wooden bedside tray. The leaves provide plant-green accents, along with one small electric green sensor light on a monitor. Palette: natural greens, wood browns and warm skin. Mood: quiet, careful and hopeful.

PB125: Biljni Nrf2 spoj koji je održao arterije funkcionalnima tijekom mirovanja u krevetu

BY NOVA CHEN · 31. lis 2026.

Biljni aktivator Nrf2 pod nazivom PB125, sastavljen od ružmarina, ashwagandhe i luteolina, testiran je u malom, dvostruko slijepom ljudskom ispitivanju. Kod 24 starijih osoba, dva tjedna suplementacije od 200 mg/dan podiglo je brahijalni FMD s 2,8 % na 3,8 %, a poplitealni FMD s 1,5 % na 2,3 %. Tijekom pet dana potpune postele, mješavina je sačuvala funkciju arterija i razinu antioksidansa u usporedbi s placebom. Mlađi sudionici nisu pokazali poboljšanje početnog FMD‑a, iako je PB125 štitio poplitealni FMD tijekom imobilizacije udova. S obzirom na mali broj sudionika i posredničke ishode, rezultat predstavlja zanimljiv signal, a ne čvrst dokaz kliničke koristi.
