This study was designed to examine the physiological changes caused by long-term training in a world class female tennis player in preparation for a major championship. Additionally, we aim to describe the training interventions and determine a suitable cooling strategy that was to be used at the 2004 Paralympic Games. The athlete underwent regular physiological assessment during 2003-2004. Phy...
Brain injuries caused by stroke are common and costly in human and resource terms. The result of stroke is a cascade of molecular and physiological derangement, cell death, damage and inflammation in the brain. This, together with infection, if present, commonly results in patients having an increased temperature, which is associated with worse outcome. The usual clinical goal in stroke is ther...
The foramen ovale, which is part of the normal fetal cardiopulmonary circulation, fails to close after birth in ∼35% of the population and represents a potential source of right-to-left shunt. Despite the prevalence of patent foramen ovale (PFO) in the general population, cardiopulmonary, exercise, thermoregulatory, and altitude physiologists may have underestimated the potential effect of this...
Outdoors activities, such as cross-country skiing, may expose the human body to severe thermal stress during training and competitive events in the winter season. Cooling affects all aspects of muscular performance (1), and cold has a profound effect on the functional properties of skeletal muscle. When exercise intensity is high enough to maintain core temperature, but skin cooling is still pr...
Parametric study of the influence of cooling channel dimensions on PEM fuel cell thermal performance
In a polymer membrane fuel cell more than half of the chemical energy of hydrogen is converted to heat during generation of electricity. This causes an increase in the cell temperature. The Cooling field design has a significant role in cell cooling. The cell's performance and stability are reduced due to inappropriate heat dissipation. In this paper, the cooling flow and heat transfer in cooli...
OBJECTIVE To investigate the effect of peripheral sustained cooling on intention tremor in patients with multiple sclerosis (MS). MS induced upper limb intention tremor affects many functional activities and is extremely difficult to treat.Materials/ METHODS Deep (18 degrees C) and moderate (25 degrees C) cooling interventions were applied for 15 minutes to 23 and 11 tremor arms of patients w...
exposure to cold work environment is an occupational health hazard and poses adverse effect on workers health, performance and productivity. this study was performed in a cold food-storage warehouse complex in tehran-iran in order to evaluate the workers' exposure to cold stress. twenty nine exposed workers and 33 non-exposed workers as control subject were included in this study. climatic fact...
AIM Cooling the pharynx and upper oesophagus would be more advantageous for rapid induction of therapeutic hypothermia since the carotid arteries run in their vicinity. The aim of this study was to determine the effects of pharyngeal cooling on brain temperature and the safety and feasibility for patients under resuscitation. METHODS Witnessed non-traumatic cardiac arrest patients (n=108) wer...
BACKGROUND Intra-arrest hypothermia induction may provide more benefit than inducing hypothermia after return of spontaneous circulation. However, little is understood about the interaction between patient physiology and hypothermia induction technology choice during ongoing chest compressions. METHODS After 10 min of untreated ventricular fibrillation, mechanical chest compressions were prov...
