Phosphatidylserine synthase plays an essential role in glia and affects development, as well as the maintenance of neuronal function.

Phosphatidylserine (PS) is an integral component of eukaryotic cell membranes and organelles. The genome contains a single PS synthase (PSS)-encoding gene () homologous to mammalian PSSs. Flies with loss-of-function alleles show a reduced life span, increased bang sensitivity, locomotor defects, and vacuolated brain, which are the signs associated with neurodegeneration.

How to evaluate appendices with borderline diameters on CT: proposal of a quick solution to overcome the limitations of the established CT criteria.

Rationale And Objectives: To propose a useful computed tomography (CT) criterion, the diameter with compression (DWC), especially in appendices with borderline diameters.

Materials And Methods: We retrospectively collected 216 patients with visible appendices on CT after clinicopathologic confirmation of appendicitis. Each CT criterion of appendicitis was evaluated by an experienced abdominal radiologist: maximal outer diameter (MOD), DWC, mural thickness and enhancement, periappendiceal infiltration, and appendicolith.
