Purpose: The impact of temperature on the coagulative response to exercise has not been well described. The purpose of this study was to assess the response of plasma thrombin-antithrombin (TAT) to exercise during exposure to both hot and cold temperatures, and to compare those responses to exercise under normal, temperate conditions. Methods: Fifteen healthy male subjects (25.3 + 4.3 years) volunteered to participate in this study. Subjects completed maximal cycle ergometer exercise tests in three different temperatures (20°C, 5° or 8° C, and 30°C) in an environmental chamber. All tests were

The influence of caffeine on the metabolic and catecholamine responses to mild exercise in a cold and a warm environment was studied in eight healthy males.

While a great deal of research has been directed towards the phenomena of excess post exercise oxygen consumption (EPOC), the effect of thermal stress on EPOC is not well defined. To assess the effect of heat stress on EPOC, seven healthy, active subjects (4 female, 3 male; 23.9 ± 2.0 years of age) performed 4 trials: one control (quiet rest) and one exercise (45 minutes of cycling at 65% VO2max workload) trial in moderate (23° C, 50% humidity) and hot (35° C, 50% humidity) environments.

Controversy exists concerning the role that dopamine plays in analgesia.

Furthermore, microinjection of morphine into the ventral tegmental area (VTA) and ventral striatum produced analgesia, while intra-VTA microinjection of naloxone methylbromide antagonized the analgesia produced by systemic

As soon as the building of the body is completed, the ageing process begins. In the natural course of events, the functioning of some organ systems finally ebbs below the threshold necessary to maintain the body, resulting in death. This occurrence is relatively rare, because diseases superimpose themselves upon the ageing process, bringing premature death resulting from pathological causes.

Eighteen-month-old adult female Peking Ducks (Anas platyrhynchos) were placed in the Ottawa, and St. Lawrence rivers for periods varying between 14 and 72 days during the summers of 1987, 1988 and 1989. Two stations located on Lake St. Francis were selected for establishing a time-curve for the accumulation of organochlorine pesticides (OC) and PCB in the liver. The ducks rapidly lost weight during their first 20 days in the natural environment but stabilised after about 40 days. This weight loss was caused by the stress of habitat, change, the energetic costs in searching for food and moultin

Staphylococcus aureus are Gram-positive bacteria that adhere to the extracellular matrix of susceptible host cells to initiate infection and induce a signal transduction pathway that includes PI3K causing the disruption of cytoskeletal elements within the cytosol. Confocal microscopy was applied to visualize actin within human umbilical vein endothelial cells (HUVEC) to discern behavior during infection. HUVEC lysates were analyzed through immunoprecipitation and Western blot analysis to determine the isoforms of PI3K present in HUVECs. Infection experiments and confocal microscopy reveal a ti

The purpose of this study was to investigate the effects of ribose supplementation on swimming performance in collegiate male swimmers. Twenty trained collegiate male swimmers (mean ± SE; age: 19.7 ± 0.4 years; height: 182.6 ± 1.2 cm; weight: 75.9 ± 0.6kg) completed three randomly assigned trials; two prior to the supplementation period and one immediately after supplementation. The period between the first and the second trial was used as a control period and all subjects (n=20) participated. During the supplementation period the ribose group (n=10) received 20 g of ribose per day, while the

The purpose of this study was to examine the effects of androstenedione supplementation on testosterone levels in older men. Healthy men (n = 11) between the ages of58 and 69 were divided into two groups: 6 taking 300 mg of androstenedione (mean ± SE, 62.33 ± 2.57) supplement and 5 taking the 300 mg cellulose placebo (mean ± SE, 60.2 ± 1.02) for a period of seven days. Subjects in both groups had been participating in the Ball State University Adult Fitness Program (BSUAFP) for at least one year, incorporating both aerobic and resistance training into their workouts. Testing measures involved

The purpose of the present study was to assess the pressure distribution responses to three hour seating bouts in a standard car seat condition compared to a Comfort Motion Technology (CMT) car seat condition. Twelve males participated in the study. Subjects came in for two separate sessions no more than one week apart. Pressure distribution on the backrest and seat pan was assessed in a three hour seating bout. Pressure variables associated with increased seating comfort were collected across six distinct 28 minute cycles and then averaged across these six cycles. The pressure variables were

Previous studies in our laboratory have indicated that anesthetic block of neural activity at discrete sites within the limbic system, including the lateral hypothalamus and anterior cingulum bundle, causes a significant long-lasting analgesia during the formalin test. In this experiment, the local anesthetic lidocaine was microinjected into the dentate region of the hippocampus, an important limbic structure presumed to subserve the affective-motivational aspects of pain. The dentate gyrus is strategically situated at a point of convergence of widespread polysensory cortical input to the hipp

The physiological responses of hypertensive subjects to a single bout of exercise in a hot environment have been investigated. It was the purpose of this study to compare the effect of successive days of exercise in the heat on borderline hypertensive and normotensive individuals, with particular interest being paid to the positive relationship that exists between plasma volume and blood pressure. Eight hypertensive subjects (HT) and 8 normotensive controls (NT) performed a standardized work task, (walking for 60 minutes at 3.5 mph on a 5% grade), in dry heat, (40C, 257. RH), on 7 successive d
