OBJECTIVE To determine if estrogen ameliorates hot flashes by raising the core body temperature sweating threshold, by reducing core body temperature fluctuations, and/or by reducing sympathetic activation (as measured by plasma 3-methoxy-4-hydroxyphenylglycol). DESIGN Laboratory physiological study. SETTING University medical center. PATIENT(S) Twenty-four healthy postmenopausal women re...
To examine the relationship between temperature (ambient and core), dopaminergic neurotoxicity, and plasma drug [methamphetamine (METH)] and metabolite [amphetamine (AMPH)] concentrations, two separate groups of squirrel monkeys (n = 4-5 per group) were treated with METH (1.25 mg/kg, given twice, 4 h apart) or vehicle (same schedule) at two different ambient temperatures (26 and 33 degrees C). ...
free vibration of sandwich plates with temperature dependent functionally graded (fg) face sheets in various thermal environments is investigated. the material properties of fg face sheets are assumed to be temperature-dependent and vary continuously through the thickness according to a power-law distribution in terms of the volume fractions of the constituents. also, the material properties of...
we investigate the temperature-dependences of the Brillouin frequency shift in three different kind of single-mode fibers using a heterodyne method for sensing temperature. Positive dependences coefficients of 0.77, 0.56 and 1.45MHz/0C are demonstrated for 25 km long single-mode fiber, 10 km long non-zero dispersion shifted fiber and 100 m photonic crystal fiber, respectively. The results indic...
Exposure of a male or nonpregnant female rat to a novel environment, such as a simulated open field, induces a transient increase in core temperature, which is often called stress-induced hyperthermia. Pregnancy alters this response such that the core temperature index increases significantly during exposure to a simulated open field on day 10 but not on days 15 and 20 of gestation in rats. The...
