the aim of this study was to evaluate the morbidity and mortality in patients with operable stage ii and iii rectal cancers within one or two months after surgery, who has been treated pre-operatively with short course radiotherapy. twenty-eight patients with rectal adenocarcinoma, consecutively referred to the cancer institute of imam khomeini hospital from march 2009 to march 2010, were selec...

bowel stent insertion has a variety of complications one major of which is colonic perforation. the purpose of this article is to reveal two cases with delayed colonic perforation after stent placement to relieve bowel obstruction caused by rectal cancer. the first patient was a 55 year-old man who was a candidate for stent placement to avoid palliative surgery and relieve his bowel obstruction...

OBJECTIVE The main objective of this study was to study the safety and efficacy of a simple, cost-effective method of selective head cooling with mild systemic hypothermia in newborn infants with hypoxic ischaemic encephalopathy. DESIGN Ethical approval was obtained for a randomized controlled study in which 20 asphyxiated neonates with clinical signs of hypoxic ischaemic encephalopathy would...

Gamma aminobutyric acid (GABA) is one of the inhibitory neurotransmitters that may have the ability torelieve the intensity of stress. Heat stress remains a major threat for duck production in summer in most areas of China. The current study was conducted to investigate the effect of dietary GABA on performanceparameters and plasma metabolites of heat exposed ducks. Two thousand Cherry Valley d...

Body temperature is a clinical parameter in vaccine quality control to detect systemic side-effects or to monitor progression of infectious diseases. Moreover, changes in body temperature are used as clinical parameters to define humane endpoints in animal experiments. However, measuring body temperature via the rectal route can be troublesome and distressing to the animal. Non-invasive measure...

The process of cooling bodies, by the use of a heart lung machine (HLM), is utilised in a number of surgical procedures primarily to reduce the metabolic rate of the organs and hence their consumption of oxygen. On completion of surgery the blood is rewarmed by the HLM. A major consequence at the end of this process is afterdrop: a rapid decrease in the core organ temperature as a result of spa...

We studied interindividual variation in body temperature and energy expenditure, the relation between these two, and the effect of mild decrease in environmental temperature (16 vs. 22 degrees C) on both body temperature and energy expenditure. Nine males stayed three times for 60 h (2000-0800) in a respiration chamber, once at 22 degrees C and twice at 16 degrees C, in random order. Twenty-fou...

I . The effects of chronically raised body temperature on lipid metabolism wcrc studied in groups of 3-month-old British (Shorthorn x Hereford) and Zebu (Africander x British) bull calves. Calves in control groups at ambient temperature were pair-fed to calvcs housed in a climate room. 2. In control groups, concentrations of plasma cholesterol and phospholipid were significantly higher and the ...

The goal of this study was to investigate the effects of different durations of skin temperature manipulation on pacing patterns and performance during a 15-km cycling time trial. Nineteen well-trained men completed three 15-km cycling time trials in 18 °C and 50% relative humidity with 4.5-km (short-heat), 9.0-km (long-heat) or without (control) radiant heat exposure applied by infrared heater...
