Molecular architectures of centrosomes in C. elegans embryos visualized by cryo-electron tomography.

Centrosomes organize microtubules that are essential for mitotic divisions in animal cells. They consist of centrioles surrounded by pericentriolar material (PCM). Questions related to mechanisms of centriole assembly, PCM organization, and spindle microtubule formation remain unanswered, partly due to limited availability of molecular-resolution structural data inside cells.

Intestinal Epithelial Serotonin as a Novel Target for Treating Disorders of Gut-Brain Interaction and Mood.

Background & Aims: Mood disorders and disorders of gut-brain interaction (DGBI) are highly prevalent, commonly comorbid, and lack fully effective therapies. Although selective serotonin reuptake inhibitors (SSRIs) are first-line pharmacological treatments for these disorders, they may impart adverse effects, including anxiety, anhedonia, dysmotility, and, in children exposed in utero, an increased risk of cognitive, mood, and gastrointestinal disorders. SSRIs act systemically to block the serotonin reuptake transporter and enhance serotonergic signaling in the brain, intestinal epithelium, and enteric neurons.

Enhancing the Graduate Medical Education Clinical Learning Environment Through Community of Practice Forums.

An optimal clinical learning environment (CLE) is associated with improved learning and patient care outcomes. Significant concerns exist about the state of the CLE in graduate medical education (GME). Research suggests that GME programming falls short in interpersonal aspects of training that promote trainee engagement and psychological safety.
