Twenty-two patients undergoing coronary artery bypass surgery underwent postoperative measurement and recording of jugular venous oxyhaemoglobin saturation (SjO2) with desaturation defined as a value of less than 50% for 5 min or longer. Fifteen of the 22 patients monitored experienced desaturations. An average of four episodes were experienced by those 15 patients (range 1-14). The mean durati...

Microsomes from rat liver were extracted by low ionic strength solutions. Extracted microsomes lost most of the linoleic acid desaturation activity. The addition of the extract back into the extracted microsomes was necessary to restore full desaturation activity. The soluble fraction had no desaturation activity. The existence of a soluble factor loosely bound to the microsomes, stable to soni...

A total of 155 consecutive anaesthetics in three public Malaysian hospitals were prospectively studied to assess preoxygenation practices by their anaesthesia providers. Preoxygenation was practised in 96.1% of patients. Specialist and non-specialist anaesthesiologist did not preoxygenate 8.8% and 2.3% of their patients, respectively. Overall incidence of arterial oxygen desaturation during ind...

Objective: In this study, we aimed to investigate the incidence of cerebral desaturation and possible relationship between intraoperative postoperative complications. Methods: A prospective, observational study was performed 115 patients under 18 years age who required open heart surgery in a university hospital. Cerebral defined as 25% decrease saturation (low alarm limit) when compared with b...

Intact spinach (Spinacia oleracea) chloroplasts, pulse-labeled with [(14)C]acetate, desaturate newly formed fatty acids as ester groups of monogalactosyl diacylglycerol in a subsequent chase in the dark. Rupture of pulse-labeled chloroplasts by addition of a detergent solution 3-([3-cholamidopropyl]dimethylammonio)-1-propane sulfonate preserves part of this desaturation activity. Direct additio...
