The effect of acute physical and mental stress on soluble cellular adhesion molecule concentration.

Aims: This study investigated the impact of acute physical and mental stress on serum concentrations of vascular cell adhesion molecule (VCAM)-1 and CX3CL1/fractalkine.

Materials And Methods: Male volunteers (n=20; 21.3±0.

G protein-coupled receptor kinase-2 in peripheral blood mononuclear cells following acute mental stress.

Aims: This study investigated G-protein-coupled receptor kinase-2 (GRK2) density in peripheral blood mononuclear cells (PBMC) and its relationship to plasma pro-inflammatory cytokine concentrations following acute mental stress.

Main Methods: Apparently healthy males (n=20; 21.3±0.

Sympathetic Activity Assessed during Exercise Recovery in Young Obese Females.

Objective: To evaluate differences in sympathetic activity, as assessed by an exercise recovery index (ERI; heart rate/oxygen consumption [VO2] plateau), between black and white obese female adolescents. An additional aim was to determine the association of ERI with insulin resistance (homeostasis model assessment of insulin resistance [HOMA-IR]), cardiovascular fitness per fat-free mass (VO2 per fat-free mass), systolic blood pressure (SBP), and percent body fat (%FAT) in both black and white obese adolescents.

Study Design: Sixty-one females volunteered to participate in this study.

Sex differences in pulmonary oxygen uptake kinetics in obese adolescents.

Objective: To determine whether sex differences exist in the pulmonary oxygen uptake (VO2) uptake on-kinetic response to moderate exercise in obese adolescents. We also examined whether a relationship existed between the VO2 on-transient response to moderate intensity exercise, steady-state VO2, and peak VO2 between obese male and female adolescents.

Study Design: Male (n = 12) and female (n = 28) adolescents completed a graded exercise test to exhaustion on a treadmill.
