Periodic breathing and apnea are common in neonates, yet the physiological mechanisms involved are not clear. A low arterial PO2 might magnify peripheral chemoreceptor contribution to breathing, with its baseline variability inducing major changes in ventilation, leading to instability of the respiratory control system. We hypothesized that neonates: (1)(More)

Due to rapid changes in requisites, universities face the challenge of being relevant. As such, it is pertinent to identify the attributes of successful universities and future learning environments for universities to steer themselves in achieving success. This study explores the perspectives of respondents pertaining to attributes of successful(More)
Lead concentrations in blood and scalp hair of 200 school boys, aged 6-8 years, were measured by electrothermal atomic absorption spectrometry. The mean blood-Pb concentration was 6.8 microg dl(-1) and the mean hair-Pb concentration was 9.7 microg g(-1) (dry weight). These values are well within the normal range for the respective tissues, indicating that(More)
