The objective of our study was to establish whether rectal temperature recordings in humans could be replaced by a non-invasive skin temperature sensor combined with a heat flux sensor (Double Sensor) located at the forehead to monitor core body temperature changes due to circadian rhythms. Rectal and Double Sensor data were collected continuously for 24h in seven men undertaking strict head-do...

Animals with anterior or posterior neocortical lesions as well as intact control animals were evaluated for changes in a-adrenergic sensitivity at five postoperative times. Colonic temperature decreases were measured in response to clonidine at each of the postoperative periods. The result indicated that a heightened heat-loss response was induced by clonidine that lasted 21 or more days after ...

The aim of this study is to investigate how elevation of body temperature changes organs blood flow during sevoflurane anesthesia. We conducted in vivo research on 14 male Wistar rats to monitor pulse rate and arterial blood pressure and measure hepatic, small intestinal, renal, and descending aortic blood flow using a laser Doppler blood flowmeter. We assessed the changes in organ blood flow, ...

The purpose of this study was to examine the effect of environmental temperature on variability in power output, self-selected pacing strategies, and performance during a prolonged cycling time trial. Nine trained male cyclists randomly completed four 40 km cycling time trials in an environmental chamber at 17°C, 22°C, 27°C, and 32°C (40% RH). During the time trials, heart rate, core body tempe...

The purpose of this study was to determine the effects of a particular psychological stress, exposure to an open-field, on plasma IL-6 activity in rats. Plasma IL-6 activity was 40.6 +/- 7.2 units/ml in control rats, 105 +/- 6.8 units/ml after 30 minutes exposure to an open-field, and 221 +/- 17 units/ml after 60 minutes of exposure (p = 0.0003). There was a positive correlation (r = .71, p = 0...

A moisture- electrical - temperature (MET) test is proposed to evaluate the outdoor reliability of high power blue LEDs, with and without phosphor, and to understand the degradation physics of LEDs under the environment of combined humidity, temperature and electrical stresses. The blue LEDs with phosphor will be the high power white LEDs. Scanning acoustic microscopy is used to examine the res...

Water evaporation has a marked effect on the passive rates of body temperature change of eristaline hoverflies. It results in the equilibrium temperature of these flies being significantly lower than ambient temperature. Different values for the cooling and warming constants are therefore obtained depending on whether equilibrium or ambient temperature is used as the baseline. Hence, care must ...

Measuring changes in core body temperature provides a valid method to detect ovulation and increase fertility. 'OvuSense' is a novel vaginal sensor that can predict the fertility window by recording and analysing the changes in intravaginal temperature records. This study aimed to determine patients 'acceptability and satisfaction after using OvuSense'. We approached 13 women to complete a pati...

Objective: To study how ear and rectal body temperatures relate to each other over time in febrile patients. Methods: Descriptive cohort study with repeated measurements. The setting was a Unit for Infectious Diseases at a county hospital in Sweden. Patients, ≥ 18 years, admitted for suspected infection and with a rectal or ear temperature of ≥ 37.5◦C were invited. 16 females and 24 men, 19 to ...
