HYDRATION EFFECTS ON COGNITIVE PERFORMANCE DURING MILITARY TASKS IN TEMPERATE AND COLD ENVIRONMENTS.
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 could mitigate any cold-induced performance [...]
SIMULTANEOUS DETERMINATION OF FLUID SHIFTS DURING THERMAL STRESS IN A SMALL-ANIMAL MODEL.
We have developed methodology to simultaneously measure fluid redistribution among the major compartments during moderate and severe hypohydration. Total body water (TBW) was determined using tritiated water, extracellular fluid volume (ECF) was measured using a single-injection [14C]inulin technique, and plasma volume (PV) was determined by indocyanine green dye dilution. Moderate (10% decrease in body wt) [...]

NO NEED FOR WATER SUPPLEMENTATION FOR EXCLUSIVELY BREAST-FED INFANTS UNDER HOT AND ARID CONDITIONS.
This study was conducted in 4 villages in India during the hottest and driest season of the year to determine whether exclusively breast-fed infants need additional water under extremely hot and dry climatic conditions. The ambient temperature was 35-40 degrees C and the relative humidity 10-35%, except during the early morning hours. 63 urine samples [...]
AGING AND THE KIDNEY: CLINICAL IMPLICATIONS.
Beyond the age of 30, kidney size begins to decrease, and there are accompanying decreases in total renal blood flow, outer cortical flow, glomerular filtration rate and the ability both to conserve and to excrete sodium. There is also a decline in concentrating ability and possibly in diluting ability. These changes make the elderly patient [...]

SWEAT GLAND RESPONSE TO EXERCISE IN THE HEAT AMONG PRE-, MID-, AND LATE-PUBERTAL BOYS.
Sweating rate (SR) of boys is lower than that of men. To assess the association between the response of individual sweat glands and physical growth and maturation, three groups of circumpubertal boys cycled at 50% VO2max in a climatic chamber (42 degrees C, 20% relative humidity). Based on Tanner staging (pubic hair), 16 were classified [...]
