It is hoped that this will provide an independent and quantifiable criterion to distinguish smithing slags (more oxidising) from smelting slags (more reducing), and to understand better the actual

smelting process that transforms highly oxidised iron ore to fully reduced iron metal. Copyright (C) 2011 John Wiley & Sons, Ltd.”
“Background: Oxygen saturation (Spo(2)) monitors are commonly used to determine the need for supplemental oxygen. We aimed to describe the range of arterial oxygen tensions (Pao(2)) observed in preterm infants at saturation levels targeted in current trials.\n\nMethods: In a cohort of 98 consecutive infants born at <29 weeks’ gestation, the Pao(2) from each arterial blood gas result during the first week of life www.selleckchem.com/products/BKM-120.html (n = 2076) was matched to the Spo(2) at time of sampling. The mean Selleckchem CYT387 (95% CI) Pao(2) was calculated for each saturation.\n\nResults: The 95% CI of Pao(2) for the Spo(2) range 85-95% was 3.8 to 8.9 kPa. The mean 195% CI) Pao(2) at a saturation of 85% was 5.3 (3.8 to 6.8) kPa and at a saturation of 95% it was 7.2 (5.5 to 8.9) kPa.\n\nConclusion:

Saturations within the range 85-95% largely exclude hyperoxia in preterm infants <29 weeks’ gestation but permit Pao(2) values far lower than those recommended in traditional guidelines.”
“The present study examined the acute behavioral responses of pigeons to separation from conspecifics and exposure to an unfamiliar environment (UE). The effects of (1) repeated exposure to the UE; (2) visual isolation from surroundings, or saline injections; and (3) Navitoclax datasheet diazepam treatment (i.p.. 0.25, 0.75, 2.5 or 7.5 mg/kg) before the trial were also examined. LIE exposure

evoked intense ballistic head movements (peeping), gradually replaced with angular head movements (AHM), both associated with immobility of the trunk and legs. These behaviors failed to habituate after three trials (7-day intertrial intervals). Visual isolation from the surroundings and saline injection prior to exposure to the UE increased the AHM and reduced peeping. Doses of diazepam (0.25 and 0.75 mg/kg) that have demonstrated anti-conflict effects in other tests did not affect the behavioral responses to the UE. Diazepam at 2.5 and 7.5 mg/kg doses consistently increased time spent in immobility. These data suggest that peeping, although expressed in potentially threatening or harmful situations appears not to be a fear-motivated behavior or, alternatively, this specific behavioral response is not diazepam sensitive.
