Evaluación de la contractilidad del ventrículo izquierdo en pacientes con estenosis aórtica grave, flujo bajo, gradiente bajo y fracción de expulsión preservada

open access: yesArchivos de Cardiología de México, 2022
Introducción: En la estenosis aórtica grave con gradiente bajo, fracción de expulsión preservada (≥ 50%) y flujo bajo (GB/FBp), la disminución del índice de volumen sistólico (IVS) podría deberse a una reducción de la contractilidad.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.
