Maternal Fish Oil Supplementation Affects the Social Behavior, Brain Fatty Acid Profile, and Sickness Response of Piglets.

Background: Maternal dietary docosahexaenoic acid (DHA) intake is thought to affect development in the offspring.

Objective: We assessed the impact of maternal dietary DHA on behavior, brain fatty acid (FA) profile, and sickness response of offspring in pigs, a pertinent model for human nutrition.

Methods: Sows (n = 24) were fed a diet with DHA-rich fish oil (FO) (20 g/kg) or high-oleic acid sunflower oil (HOSF) (20 g/kg) from day 61 of gestation through lactation.

Incidence of ventricular arrhythmias after stem cell therapy in patients with Chagas cardiomyopathy.

Background: Treatment with stem cells in several cardiomyopathies may be related to the increase in arrhythmias.

Objectives: To determine whether intracoronary injection of stem cells in patients with Chagas cardiomyopathy is associated with increased incidence of ventricular arrhythmias, compared to the Control Group.

Methods: A retrospective cohort study that evaluated the medical records of 60 patients who participated in a previous cross-sectional study.

Relations between peripheral and brain serotonin measures and behavioural responses in a novelty test in pigs.

Pigs differ in their behavioural responses towards environmental challenges. Individual variation in maladaptive responses such as tail biting, may partly originate from underlying biological characteristics related to (emotional) reactivity to challenges and serotonergic system functioning. Assessing relations between behavioural responses and brain and blood serotonin parameters may help in understanding susceptibility to the development of maladaptive responses.
