Forty Najdi ram lambs weighing 26.6±0.3 kg were utilized in this experiment to determine the effects of feed restriction followed by realimentation and body weight at the onset of feed restriction (30 and 36 kg body weights) on performance and carcass characteristics; feeding and restriction levels were ad libitum, 0.75 and 0.60 of the ad libitum intake. All lambs were slaughtered after 14 week...

The restriction endonuclease BliAI, an isoschizomer of ClaI, which recognizes the sequence 5 ́AT↓CGAT 3 ́, was purified from a natural isolate identified as Bacillus licheniformis. The restriction endonuclease was isolated from cell extracts using single-step purification by phosphocellulose column chromatography. The restriction endonuclease is active at 37oC and over a wide range of pH and salt...

OBJECTIVES To analyze the effects of nutritional restriction and hyperoxia on lung weight and pulmonary morphometry in premature rabbits during the first 11 days of life. METHODS New Zealand White rabbits were delivered by C-section at 28 days' gestational age and randomized into four groups: control diet and room air, control diet and hyperoxia (> or = 95% O2), nutritional restriction and ro...

The objective of this study was to investigate whether pregnancy, delivery, and neonatal outcome among obese pregnant women who took part in an intervention study for weight restriction differed from a group of obese pregnant women attending regular antenatal care. The intervention group consisted of 155 obese pregnant women and 193 obese pregnant women who formed a control group. We found that...
