abstract: the global warming process during last century has not only affected on meteorological elements but also affected on onset and end of each meteorological elements. for studying probability changes in time series of onset and end date of temperature thresholds 0 and 5 centigrade in country level and deciding the kind and its direction, daily temperature data during the past 45 years (1...

I . Male hooded Lister rats given a diet containing 40 mg zinc/kg were described as Znadequate. Other rats were subsequently given diets containing less than I m g Zn/kg. After a period of approximately 5 d these animals ceased to grow and were described as Zn-deficient. 2. Zn-deficient rats offered ad lib. a Zn-deficient diet containing 200 g egg albumenjkg ate only 55 "/o of the weight eaten ...

Huddling is the key energy-saving mechanism for emperor penguins to endure their 4-mo incubation fast during the Antarctic winter, but the underlying physiological mechanisms of this energy saving have remained elusive. The question is whether their deep body (core) temperature may drop in association with energy sparing, taking into account that successful egg incubation requires a temperature...

One such method, Differential Scanning Calorimetry (DSC), detects WAT by measuring the difference in heat absorbed or released between a reference sample and the test sample at a given cooling or warming rate. The WAT is detected by a deviation of experimental data from the reference baseline and typically requires a significant amount of wax formation for sensible detection. Consequently, it m...

1. Body temperature, blood glucose, lactate, plasma free fatty acid and noradrenaline responses to exercise were studied in hyperthyroid patients during 30 min exercise on a bicycle ergometer at a work load producing a heart rate of approximately 135-140 beats/min. The results were compared with those obtained in healthy subjects exercising at work loads comparable in terms of oxygen uptake. 2....

Although the general complication rate for vertebroplasty is low, neural compression and thermal damage have been related to the use of polymethyl-methacrylate cement. This study focuses on the risk of thermal tissue damage after vertebroplasty. In this study, cavities were created by a transpedicular approach in the vertebral bodies (L3, L4, and L5) of four milk goats, and polymethyl-methacryl...

Hypocretin (Hcrt) has been implicated in the control of motor activity and in respiration and cardiovascular changes. Loss of Hcrt in narcolepsy is linked to sleepiness and to cataplexy, a sudden loss of muscle tone which is triggered by sudden strong emotions. In the current study we have compared the effects of treadmill running, to yard play on cerebrospinal fluid (CSF) Hcrt level in normal ...

BACKGROUND Transurethral resection of the prostate gland with irrigation fluid at room temperature leads to perioperative hypothermia which could give rise to adverse cardiovascular events in the perioperative period. The use of isothermic irrigation fluid reduces but does not eliminate this risk. Routine use of warm intravenous fluids along with isothermic irrigation had not been documented. T...

HOWELL, B. J., F. MT, BAUMGARDNER, K, BONDI, AND H. RAHN. Acid-base balance in cold-blooded vertebrates us a function of body temperuture. Am. J. Physiol. 218(Z) : 600-606. 1970.-Arterial blood pH values of unanesthetized frogs, toads, and turtles vary inversely with the temperature to which the animal has been acclimated. MeanA pH/A t for the three species is -0.016 between 5 and 37 C. PCO, in...

The Bod Pod has been found to be reliable/valid against several criterion methods, including hydrostatic weighing and dual-energy x-ray absorptiometry, and under different conditions, such as clothing, dehydrated states, and body temperature changes. However, questions remain regarding the effects of an acute bout of exercise. Therefore, the purpose was to determine the effects of an acute bout...
