Sensitive temperature gradiometer for use at low temperatures
Review of Scientific Instruments, 1978A device capable of very sensitive temperature gradient measurements in the presence of relatively large ambient temperature fluctuations is described. The device uses a pair of ’’matched’’ superconducting thin films in a bridge arrangement, with a SQUID magnetometer probe as the null detector.

Temperature sensitive auditory neuropathy
Hearing Research, 2016Temperature sensitive auditory neuropathy is a very rare and puzzling disorder. In the present study, we reported three unrelated 2 to 6 year-old children who were diagnosed as auditory neuropathy patients who complained of severe hearing loss when they had fever. Their hearing thresholds varied from the morning to the afternoon. Two of these patients'

Temperature-Sensitive Hydrogels [PDF]
American Journal of Drug Delivery, 2005 Thermo-sensitive polymers are appealing materials for several therapeutic applications, such as in regenerative medicine and in situ drug release. These macromolecules are characterized by the ability to undergo swelling/deswelling processes during temperature change-induced phase transitions.

Pseudofacilitation: A temperature-sensitive phenomenon
Muscle & Nerve, 2000With sustained isometric exercise, compound muscle action potential (CMAP) amplitude of normal subjects may increase, a phenomenon known as pseudofacilitation. To explore the mechanism of pseudofacilitation, the effect of exercise combined with focal heating and cooling of abductor pollicis brevis was examined in 10 normal subjects.

Temperature Sensitivity of Myosin and Actomyosin
Canadian Journal of Biochemistry, 1973The thermal denaturation of myosin and actomyosin was studied by active site analysis (enzymatic activity) and measurements were related to overall conformational changes (viscosity) over the temperature range 19–65 °C. The role of sulfhydryl (SH) groups on the temperature-induced denaturation of actomyosin was investigated. The temperature of maximum

Effect of temperature on sensitivity of the finger
Journal of Applied Physiology, 1963Subjects reported the detection of impacts from objects falling upon the ball of the finger. At a given point on the skin a falling weight of 1 mg might be detected after falling 10 mm, and twice the weight would then be detected after falling 5 mm. Droplets of mercury expelled by a Scholander micrometer burette afforded one series of measurements. On

A temperature-sensitive respiratory alarm
Clinical Physics and Physiological Measurement, 1983Describes a novel alarm which is designed to monitor respiration in a patient undergoing intermittent positive pressure ventilation. The alarm operates by sensing the temperature differences between the inspired and expired gas using a thermistor mounted close to the point in the breathing circuit where the patient connection is made. It offers several

Generation of a Temperature-Sensitive cSRC
Virology, 1993We have created retroviruses encoding a temperature-sensitive variant of the cSrc protein, and of its activated allele cSrc(Y527F). Cells expressing the activated allele harboring this mutation displayed a transformed phenotype when grown at 34 degrees, but not at 39 degrees, as quantitated by measuring the susceptibility of the cells to contact ...

A temperature-sensitive cardiac pacemaker
Journal of Medical Engineering & Technology, 1983An artificial cardiac pacemaker which is sensitive to the temperature of blood in the right atrium has been fabricated. For a temperature change of 20 degrees C the circuit achieves 90% of its final response within a period of 18 s. In the authors' opinion this is satisfactory since changes in blood temperature are generally small.

Temperature sensitivity and fluorescence detection
Journal of Separation Science, 2008AbstractFluorescence detectors are about three orders of magnitude more sensitive and specific making them ideal for trace analysis and complex sample matrices. However, temperature dependence of the signal is a disadvantage to fluorescence detectors. We have previously reported degradation of malondialdehyde (MDA)–thiobarbituric acid (TBA) adduct at ...
