OBJECTIVE Previous work has found cerebral oxygen extraction to decrease during hypothermic cardiopulmonary bypass in children. To elucidate cardiopulmonary bypass factors controlling cerebral oxygen extraction, we examined the effect of perfusate temperature, pump flow rate, and hematocrit value on cerebral hemoglobin-oxygen saturation as measured by near infrared spectroscopy. METHODS Forty...

cold agglutinins are of unique relevance in cardiac surgerybecause of the use of hypothermic cardiopulmonary bypass (cpb). cold autoimmune diseases are defined by the presence of abnormal circulating proteins (usually igm or iga antibodies) that agglutinate in response to a decrease in body temperature. these disorders include cryoglobulinemia and cold hemagglutinin disease.immunoglobulin m aut...

arterial sclerosis has been extensively described but reports on venous sclerosis are very sparse. phlebosclerosis refers to the thickening and hardening of the venous wall. despite its morphological similarities with arteriosclerosis and potential morbid consequences, phlebosclerosis has gained only little attention. we report a 72 year old male with paralysis and atrophy of the right leg due ...

introduction eating disorders and morbid obesity have become common over the recent years. laparoscopic gastric bypass surgery is known as one of the most effective methods for weight loss. due to the rarity of studies regarding the association of depression and surgery, we aimed to compare the levels of depression in patients with excessive obesity before and after gastric bypass surgery. conc...

  In this paper, we consider a flow shop scheduling problem with bypass consideration for minimizing the sum of earliness and tardiness costs. We propose a new mathematical modeling to formulate this problem. There are several constraints which are involved in our modeling such as the due date of jobs, the job ready times, the earliness and the tardiness cost of jobs, and so on. We apply adapte...

An experiment was conducted in early lactating buffaloes for the period of 3 months in Jadakheria and Polisimal village of LimkhedaTaluka in Dahod district of Gujarat to assess the effect of supplementation of bypass fat on milk production, composition, body weight change and economic efficiency. Forty buffaloes in their 2nd and 3rd lactation were equally divided in completely randomized design...
