Low folate status enhances pregnancy changes in plasma betaine and dimethylglycine concentrations and the association between betaine and homocysteine

submitted by: Michelle Murphy
ABSTRACT Background: Folate, choline, and betaine participate in homocysteine metabolism. It is not known whether they interact during pregnancy. Objective: The objective was to investigate how folate status affects choline, betaine, and dimethylglycine during pregnancy. Design: Fasting plasma folate, cobalamin, free choline, betaine, dimethylglycine, and total homocysteine (tHcy) were measured longitudinally at ,12, 15, 24–27, and 34 gestational weeks (GW); at labor (nonfasting);...

biosights: May 13, 2013 - Ventral lamellipodia plug the gaps

submitted by: JCB
When leukocytes enter or exit the blood stream, they leave small wounds both in and between the vascular endothelial cells, which must be quickly repaired so that the endothelium can maintain its barrier function. Martinelli et al. reveal that wounding causes a loss of tension in endothelial cells, inducing the formation of ventral lamellipodia that close the holes left by transmigrating leukocytes. This biosights episode presents the paper by Martinelli et al. from the April 29, 2013, issue...

Bacterial Aerotaxis

submitted by: mhrussel

Aerotaxis is the movement of an organism in response to environmental oxygen concentrations, either towards or away from a given oxygen concentration. Many bacteria are microaerophilic meaning they prefer environments with low oxygen content. Higher or lower O2 content than the optimum are considered a repellant and bacteria will navigate towards the optimum. This animation is an overview of studying aerotaxis in motile bacteria.
