Steryl esters (SE) are a storage pool of sterols that accumulates in cytoplasmic lipid droplets and helps to maintain plasma membrane sterol homeostasis throughout plant growth and development. Ester formation in plant SE is catalyzed by phospholipid:sterol acyltransferase (PSAT) and acyl-CoA:sterol acyltransferase (ASAT), which transfer long-chain fatty acid groups to free sterols from phospholipids and acyl-CoA, respectively. Comparative mass spectrometry-based metabolomic analysis between ripe fruits and seeds of a tomato (Solanum lycopersicum cv Micro-Tom) mutant lacking functional PSAT and ASAT enzymes (slasat1xslpsat1) shows that disruption of SE biosynthesis has a differential impact on the metabolome of these organs, including changes in the composition of free and glycosylated sterols.

Design And Methods: This quasi-experimental study was conducted at a teaching hospital. For the therapeutic play session, disposable gloves filled with compressed air and designed to resemble a human face, syringes, and saline solution ampoules were used.
Purpose: The aim of the study was to analyze how face masks influence speech perception and time spent looking at the speaker's mouth and eyes by adults with and without hearing loss.
Method: Twenty participants with hearing loss and 20 without were asked to repeat Spanish words presented in various conditions, including different types of face masks (no mask, transparent window mask, and opaque mask FFP2) and presentation modes (audiovisual, video only, and audio only). Recognition accuracy and the percentage of time looking at the speaker's eyes and mouth (dwell time) were measured.
