Negligible Effects of Nutraceuticals from Beetroot Extract on Cardiovascular and Autonomic Recovery Response following Submaximal Aerobic Exercise in Physically Active Healthy Males: A Randomized Trial.

Background: There is little evidence that nutraceuticals from beetroot extract are beneficial with regards to recovery of the cardiovascular parameters and the autonomic nervous system (ANS) after submaximal aerobic exercise, though this formulation is employed widely for this purpose.

Objective: To study the effects of beetroot extract supplementation on the recovery of cardiorespiratory and autonomic parameters after a session of submaximal aerobic exercise.

Methods: Sixteen healthy male adults commenced a cross-over, randomized, double-blind and placebo-controlled trial.

Does bariatric surgery improve cardiac autonomic modulation assessed by heart rate variability? A systematic review.

Our study aimed to explore the influence of bariatric surgery (BS) on heart rate (HR) variability (HRV) through a systematic review. Manuscripts were selected based on electronic searches of the MEDLINE, EMBASE, and CINAHL databases from the inception of each database up to year 2020, and followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. Searching of these studies was systematized using the Population Intervention Comparison Outcome Study Design strategy.

Effects of perinatal protein malnutrition and fenfluramine action on food intake and neuronal activation in the hypothalamus and raphe nuclei of neonate rats.

In neonatal rats, hunger and satiety responses occur particularly via dehydration and gastric distention, respectively. The control of food intake in newborns is yet to be fully consolidated, particularly with respect to the participation of the hypothalamic nuclei and their relationship with the serotonergic pathway. Moreover, it is unclear how the environmental stressors in early life, like undernutrition, interfere in these events.

Early exposure of dams to a westernized diet has long-term consequences on food intake and physiometabolic homeostasis of the rat offspring.

This study evaluated the long-term effects of a westernized diet during pregnancy and lactation. Female Wistar rats (n = 12) were divided into two groups according to their food intake, namely, control (C) or westernized (W) diet, throughout pregnancy/lactation. On the 21st day, the male pups were weaned on a standard diet as follows: Control diet (CC) (n = 8) and westernized diet in perinatal life followed by control diet post weaning (WC) (n = 8).

Effects of a westernized diet on the reflexes and physical maturation of male rat offspring during the perinatal period.

This study evaluates the effects of a westernized diet during the perinatal period on the maternal performance and growth and development of rat offspring. Female Wistar rats were fed with either a control (C) diet, with casein as the protein source or a westernized (W) diet, during pregnancy and lactation. The pups were divided, eight per group, into the same diet groups as their dams.
