Background An evaluation of the developmental competence of vitrified mouse germinal vesicle (GV) oocytes with various equilibration and vitrification times; in the presence or absence of cumulus cells and by comparison between the cryotop method and straws was performed. MaterialsAndMethods Mouse GV oocytes were considered in cumulus-denuded oocytes (CDOs) and cumulus-oocyte complexes (COCs) g...

OBJECTIVES To study the training effects of eight weeks of stair climbing on Vo2max, blood lipids, and homocysteine in sedentary, but otherwise healthy young women. METHODS Fifteen women (mean (SD) age 18.8 (0.7) years) were randomly assigned to control (n = 7) or stair climbing (n = 8) groups. Stair climbing was progressively increased from one ascent a day in week 1 to five ascents a day in...

We retrospectively analyzed exercise treadmill and coronary angiographic data of 2,193 men to compare heart rate (HR) recovery with angiographic and mortality data during a follow-up study of 7 +/- 2.7 years. Only the first 2 minutes of HR recovery predicted mortality (p <0.001), and the HR decrease during the second minute of recovery predicted the presence of coronary artery disease (p <0.05).

Context: Stretching exercise regimens are routinely prescribed to increase range of motion (ROM) and diminish injuries. Objective: To examine the effect of a 3-minute passive stretch on ankle-dorsiflexion ROM in a nonpathological population. Setting: University laboratory. Design: Prospective, randomized, controlled study. Participants: 24 apparently healthy volunteers. Interventions: Subjects ...
