Caffeine Supplementation Effects on Concurrent Training Performance in Resistance-Trained Men: A Double-Blind Placebo-Controlled Crossover Study.

The aim of the present study was to investigate the effects of acute caffeine supplementation on the performance during a session of resistance training alone (RT) or in combination with aerobic training (i.e. concurrent training; CT).

Effects of exercise cessation on adipose tissue physiological markers related to fat regain: A systematic review.

Tissues usually super compensate during the period that follow physical exercise. Although this is widely accepted for muscle and glycogen, the compensatory effect is not usually applied to fat tissues. Notwithstanding, evidence for this has been present since the 1970s when it was first suggested that the increased lipogenic activity in response to training might be an adaptation that enables to restore an energy reserve that can be used in times of need.

Effects of continuous moderate exercise with partial blood flow restriction during hemodialysis: A protocol for a randomized clinical trial.

Chronic kidney disease (CKD) is associated with physical weakness and increased oxidative stress and inflammation levels. Rehabilitation programs are associated with an improvement in the functional capacity, inflammatory and oxidative stress profile. Exercise associated with blood flow restriction (BFR) has been demonstrating positive effects in training programs, but there is lack information about exercise with BFR in CKD.

A new technique for low-volume continuous sampling of spent dialysate: a validation study.

The measure of hemodialysis (HD) adequacy recommended nowadays by most guidelines, Kt/V-urea, presents significant drawbacks. Direct dialysis quantification (DDQ) through total dialysate collection (TDC), considered the gold standard measure of HD adequacy, is cumbersome, which precludes its widespread use in clinical practice. The present study aims to validate a low-volume continuous sampling of spent dialysate (CSSD).

Exploring the complexity: the interplay between the angiotensin-converting enzyme insertion/deletion polymorphism and the sympathetic response to hemodialysis.

Patients on hemodialysis (HD) are at increased risk for arrhythmias and sudden cardiac death. Autonomic nervous system (ANS) dysfunction seems to participate in the arrhythmogenic process. Genetic factors have an impact on ANS modulation, but the specific role of the insertion/deletion (I/D) polymorphism in the gene for angiotensin-converting enzyme (ACE) has not been investigated.

Insulin stimulation of Akt/PKB phosphorylation in the placenta of preeclampsia patients.

Context And Objective: Preeclampsia is a multi-systemic disease and one of the most frequent severe health problems during pregnancy. Binding of insulin triggers phosphorylation and activates cytoplasmic substrates such as phosphatidylinositol 3 kinase (PI3K). Phosphorylation of membrane phosphoinositide 2 (PIP2) to phosphoinositide 3 (PIP3) by PI3K starts Akt/PKB activation.

Signalization of Akt/PKB in the placenta, skeletal muscle and adipose tissue of preeclampsia patients.

Unlabelled: Preeclampsia (PE) is a significant cause of fetal and maternal mortality around the world and there is evidence that insulin resistance has been implicated in the pathophysiology of PE. The Akt/PKB pathway is stimulated by insulin and performs several vital functions relative to growth, survival and cellular metabolism.

Objective: To investigate the basal expression of Akt/PKB, HSP90 expression, proteins that regulate Akt/PKB activity and substrate in the placenta, skeletal muscle and adipocytes of normal and PE parturient.
