Analysis of energy pathways is useful in helping to understand adaptations to specific sports practices, which vary according to the type of effort and individual characteristics of the athletes. In this sense, this study aimed to describe the physiological changes related to lipid markers in amputee athletes who practice para-sport jiu-jitsu. This is an observational study, which included three male amputee athletes, aged between 41 and 46 years old and with more than 24 months of experience at a professional level.

Sperm activation occurring in both male and female reproductive tract involves a highly complex series of biomolecular dynamics, particularly on membrane lipids and proteins. In mammals, the universal anticipation in cholesterol (CHO) sequestration plays a role in mammalian sperm maturation/capacitation, subsequently enhancing sperm fertilizing ability. In shrimp, we have previously shown that the level of cholesterol (CHO) is significantly reduced in vas deferens sperm when compared with sperm in the testes, presumably due to the sequestering action of the lipid-binding protein, one of which is Niemann-Pick Type C-2 (NPC2).

Molecular oxygen (O) is essential for life, and continuous effort has been made to understand its pathways in cellular respiration with all-atom (AA) molecular dynamics (MD) simulations of, e.g., membrane permeation or binding to proteins.

Vesicles play critical roles in cellular materials storage and signal transportation, even in the formation of organelles and cells. Natural vesicles are composed of a lipid layer that forms a membrane for the enclosure of substances inside. Here we report a coacervate vesicle formed by the liquid-liquid phase separation of cholesterol-modified DNA and histones.

Coronary heart disease (CHD) is the leading cause of morbidity and mortality worldwide despite significant improvements in diagnostic modalities. Emerging evidence suggests that erythrocytes, or red blood cells (RBCs), are one of the most important contributors to the events implicated in atherosclerosis, although the molecular mechanisms behind it are under investigation. We used NMR-based lipidomic technology to investigate the RBC lipidome in patients with CHD compared to those with normal coronary arteries (NCAs), all angiographically documented, and its correlation with coronary artery stenosis.
