Leucine Supplementation Improves Effort Tolerance of Rats With Hyperthyroidism.

Leucine is a regulator of protein metabolism and information on its action on effort tolerance of both animals and humans with hyperthyroidism is scarce. The objective of the present study was to verify the influence of leucine supplementation on the effort tolerance of Wistar rats with experimental hyperthyroidism. 40 animals were divided into four groups of ten: control (C), hormone (H), leucine (L), and hormone + leucine (HL).

Blood pressure variability in the elderly. Association between postprandial and sleeping periods.

Introduction: The variability of arterial blood pressure (BP) is considered an important cardiovascular risk factor.

Objective: To verify the possible associations between the postprandial and the sleeping blood pressure variability.

Methods: This study evaluated systolic, diastolic, mean, pulse pressures and heart variability in 69 elderly patients in preprandial, postprandial and sleeping periods.
