Autophagy

Macroautophagy/autophagy is an evolutionarily conserved process through which cells degrade cytoplasmic substances via autophagosomes. During the initiation of autophagosome formation, the ULK/Atg1 complex serves as a scaffold that recruits and regulates downstream ATG/Atg proteins and ATG9/Atg9-containing vesicles. Despite the essential role of the ULK/Atg1 complex, its components have changed during evolution; the ULK complex in mammals consists of ULK1 (or ULK2), RB1CC1, ATG13, and ATG101, whereas the Atg1 complex in the yeast lacks Atg101 but instead has Atg29 and Atg31 along with Atg17.

Biological sex influences the life course development of blood pressure, systemic arterial hypertension, and hypertension-associated complications through neural, hormonal, renal, and epigenetic mechanisms. Sex hormones influence blood pressure regulation through interaction with several main regulatory systems, including the autonomic nervous system, the renin-angiotensin-aldosterone system, endothelin, and renal mechanisms. The modulation of vascular function by sex hormones varies over the lifespan.

Background: Fetal tachycardias can cause adverse fetal outcomes including ventricular dysfunction, hydrops, and fetal demise. Postnatally, ECG is the gold standard, but, in fetal practice, echocardiography is used most frequently to diagnose and monitor fetal arrhythmias. Noninvasive extraction of the fetal ECG (fECG) may provide additional information about the electrophysiological mechanism and monitoring of intermittent arrhythmias.

Biological sex, hormones, and gender uniquely affect health and disease, often resulting in disparities for women across the lifespan and from different racial and ethnic groups, geographical locations, and socioeconomic backgrounds. Without intentional investment and infrastructure to support good health and wellbeing for women, half of the world's population remains vulnerable to preventable morbidity and mortality. The Society for Women's Health Research and ECHAlliance-The Global Health Connector convened a women's health program as part of the 10th Annual Science Summit during the United Nations 79th General Assembly.

Globular proteins, traditionally regarded as non-structural biomolecules due to the limited load-bearing capacity in their monomeric states, are increasingly recognized as valuable building blocks for functional-mechanical materials. Their inherent bioactivity, chemical versatility, and structural tunability enable the design of materials that combine biological functionality with tailored mechanical performance. This review highlights recent advances in engineering globular proteins-spanning natural systems (serum albumins, enzymes, milk globulins, silk sericin, and soy protein isolates) to recombinant architectures including tandem-repeat proteins-into functional-mechanical platforms.
