We aimed to evaluate the effects and the interaction of size of the preovulatory follicle (POF) and long-acting progesterone (P4) supplementation after timed-AI on CL function and pregnancy success in beef cows. In experiment 1, ovulations of beef cows were synchronized starting on Day -10, and cows were split to receive sodium cloprostenol (large follicle(More)
BACKGROUND Hypophosphatemia is a disorder with potential complications and is often unrecognized in critically ill patients. AIMS To identify the prevalence of hypophosphatemia and risk factors associated to this disorder in critically ill children. METHODS In a prospective cohort study, 82 children admitted consecutively to a pediatric intensive care(More)
OBJECTIVE The aim of this study was to examine the plasma retinol of children in the acute phase of pneumonia and after recovery and to investigate the association between plasma levels of retinol after recovery with socioeconomic variables, nutritional status and severity of pneumonia. METHODS A prospective cohort study which included 40 low-income(More)
BACKGROUND Neuromuscular blocking agents (NMBA) are commonly administered to critically ill children in pediatric intensive care units (PICU) in the USA and Europe. Although NMBA are frequently used in PICU patients, their role in the PICU setting has not yet been clearly defined. The aim of this study was to describe the sustained administration of NMBA(More)
In beef cattle, proestrus estradiol and subsequent progesterone (P4) concentrations can regulate the endometrial characteristics and thereby determine maternal receptivity toward the embryo. However, the underlying mechanisms linking periovulatory endocrine profiles to receptivity, which is crucial to obtain pregnancy, need to be elucidated. We hypothesized(More)
Strategic supplementation of P4 may be used to increase conception rates in cattle, but timing of supplementation in relation to ovulation, mass of supplementary P4 and formulation of the P4-containing supplement has not been determined for beef cattle. Effects of supplementation of long-acting progesterone (P4) on Days 2 or 3 post-ovulation on development,(More)
Background: Considering that modification in body composition and growth velocity leads to alterations in zinc and copper nutritional status, the purpose of the study was to assess erythrocyte zinc and serum copper in adolescents of both genders, according to the stage of sexual maturity at different growth phases. Methods: Two hundred and eighty-six(More)
