PURPOSE: To investigate the effect of drink temperature on cycling capacity in the heat. METHODS: On two separate trials, eight males cycled at 66 +/- 2% VO2peak (mean +/- SD) to exhaustion in hot (35.0 +/- 0.2 degrees C) and humid (60 +/- 1%) environments. Participants ingested three 300-mL aliquots ...

Fructans are fructose-based polymers associated with freezing tolerance. They might act directly via membrane stabilization or indirectly by stimulating alternative cryoprotectants. Fructans and fructan biosynthetic enzymes, in general, are believed to be present in the vacuole. This paper draws particular attention to the surprising presence of fructans and fructan exohydrolase ...

This study aimed to compare the efficacy of hot/cold contrast water immersion (CWI), cold-water immersion (COLD) and no recovery treatment (control) as post-exercise recovery methods following exhaustive simulated team sports exercise. Repeated sprint ability, strength, muscle soreness and inflammatory markers were measured across the 48-h post-exercise period. Eleven male team-sport ...

Terlipressin is a synthetic analogue of vasopressin, which has been used in the treatment of acute variceal hemorrhage. In contrast to vasopressin, terlipressin can be administered as intermittent injections instead of continuous intravenous infusion. Thus, it has a less adverse reaction than vasopressin. We report a case of ischemic skin ...

In cold-temperate climates, overwintering aquatic ranid frogs must survive prolonged periods of low temperature, often accompanied by low levels of dissolved oxygen. They must do so with the energy stores acquired prior to the onset of winter. Overwintering mortality is a significant factor in their life history, occasionally reaching 100% ...

To measure how ultrasound attenuation by contrast agent microbubbles (MBs) in superficial tissue affects petechiae creation in underlying deep tissue. Studies using Sprague-Dawley rats were approved by the Animal Care and Use Committee. MBs were injected intravenously, and 12 ultrasound pulses (100 sinusoids of 1 MHz ultrasound per pulse) were ...

The present study examined how acute dissociation, trait-like dissociative symptoms, and physiological reactivity relate to each other. Sixty-nine undergraduate students were exposed to 14 aversive auditory probes, while their skin conductance responses were measured. A combination of self-reported anxiety and trait-like dissociation was found to predict variability in peritraumatic dissociation ...

Despite aromatherapy's popularity, efficacy data are scant, and potential mechanisms are controversial. This randomized controlled trial examined the psychological, autonomic, endocrine, and immune consequences of one purported relaxant odor (lavender), one stimulant odor (lemon), and a no-odor control (water), before and after a stressor (cold pressor); 56 healthy men and ...

Recent studies have demonstrated that bedside cranial burr hole and insertion of intraparenchymal catheters for intracranial pressure monitoring performed by intensive care physicians is a safe procedure, with a complication rate comparable to other series published by neurosurgeons. The overall morbidity rate is comparable to, or even lower than, that ...

OBJECTIVE: It is well established that a combination of factors, including ethnicity, may influence an individual's response to cold stress. Previous work from our laboratory has demonstrated that when faced with a cold challenge, there is a similar response in heat production between Caucasian (CAU) and African American (AA) individuals ...

The skin electrical properties are identified using a standard NeuroMuscular Electrical Stimulation (NMES) voltage pulse. The three component series equivalent electrical model was chosen to account for the skin electrical properties. The values of each of these three electrical components of the equivalent electrical model were identified and compared throughout ...

Compared with temperate birds, tropical birds have low reproductive rates, slow development as nestlings, and long lifespans. These "slow" life history traits are thought to be associated with reduced energy expenditure, or a slow "pace of life." To test predictions from this hypothesis, we measured exercise-induced peak metabolic rates (PMR(E)) ...

Body water deficits or hypohydration (HYP) may degrade cognitive performance during heat exposure and perhaps temperate conditions. Cold exposure often induces HYP, but the combined effects of cold and HYP on cognitive performance are unknown. This study investigated whether HYP degrades cognitive performance during cold exposure and if physical exercise ...

Cold thermoregulatory models (CTM) have primarily been developed to predict core temperature (T(core)) responses during sedentary immersion. Few studies have examined their efficacy to predict T(core) during exercise cold exposure. The purpose of this study was to compare observed T(core) responses during exercise in cold water with the predicted T(core) ...

The niacin skin test reflects a flush and oedema owing to the production of prostaglandin D2 from arachidonic acid. A diminished response may indicate abnormalities in the phospholipid metabolism, which has been shown in schizophrenia. There is evidence that dyslexia might also involve phospholipid abnormalities, therefore we examined the skin ...

The major indication for testosterone (T) treatment is male hypogonadism that is characterized by low serum T concentrations. Although a recently developed hydroalcoholic gel, Androgel, containing 1% T addresses many of the problems associated with the more conventional formulations, the bioavailability of T is only 10% requiring 5 to 10 ...

Participants in prolonged, physically demanding activities in cold weather are at risk of a condition known as "hiker's hypothermia". During exposure to cold weather, the increased gradient favoring body heat loss to the environment must be balanced by physiological responses, clothing, and behavioral strategies that conserve body heat stores, or ...

Psychotic symptoms such as delusions and hallucinations can have a devastating effect on a patient's social functioning. Since psychosis is rarely congenital, it is possible that lifestyle factors play a role in its etiology. This paper offers a hypothesis that some of these factors could be: (a) A lifestyle lacking ...

Exercises testing and cold air challenges are frequently used to assess airway hyperresponsiveness (AHR), but different goals are set for the two tests. We, therefore, wished to determine whether cold air and exercise challenge testing yielded similar responses and if any differences were due to differences in the maximum minute ...

Human skin barrier function is evaluated by measuring transepidermal water loss (TEWL). However, this conventional method has not been applied to assess canine skin barrier function because the equipment is not suitable for dogs due to the effects of air turbulence resulting from movement of the subject and vapor from ...

Environmental stress deleteriously affects every aspect of an ectotherm's biological function. Frequent exposure of terrestrial insects to temperature variation has thus led to the evolution of protective biochemical and physiological mechanisms. However, the physiological mechanisms underlying the positive impact of fluctuating thermal regimes (FTRs) on the fitness and survival of ...
