Direct and maternal genetic and environmental variances and covariances were estimated for weaning weight and growth and maturing traits derived from the Brody growth curve. Data consisted of field records of weight measurements of 3,044 Angus cows and 29,943 weaning weight records of both sexes. Growth traits included weights and growth rates at 365 and 550 d, respectively. Maturing traits inc...

BACKGROUND Noninvasive ventilation has been studied as a means of reducing complications among patients being weaned from invasive mechanical ventilation. We sought to summarize evidence comparing noninvasive and invasive weaning and their effects on mortality. METHODS We identified relevant randomized and quasirandomized trials through searches of databases, conference proceedings and grey l...

BACKGROUND At present, air way support plays pivotal role in management of patients in the ICU (Intensive Care Unit) and also RCU (Respiratory Care Unit). Ventilator weaning is an important step in the care of ICU and RCU patients. It is the gradual removal of mechanical ventilatory support. Different predictors are used for initiation of weaning. This study was designed to investigate the rapi...

Mothers of the Atlantic grey seal, Halichoerus grypus , lactate for about 20 days, during which they do not feed and may have no access to water. Following weaning, depart sea leaving their pups unattended unfed up another 40 days. We are interested in how this lactation strategy supports pups’ rapid growth development while also preparing them long fast before independently going sea. report a...
