Hypothalamic Thermosensitivity in Mammals

1978
Hypothalamic thermosensitivities of 21 species of mammals ranging in body size from 15 g to 34 Kg are surveyed. It is concluded that hypothalamic thermosensitivity as measured by the proportionality constant relating rate of metabolic heat production to hypothalamic temperature at a thermoneutral ambient temperature is inversely related to body size ...

A comparison between total body thermosensitivity and local thermosensitivity in mammals and birds

Pfl�gers Archiv European Journal of Physiology, 1984
We have investigated how total body thermosensitivity in various mammalian and avian species (mouse, rat, golden hamster, guinea pig, rabbit, dog, goat, pigeon, duck, goose) is related to their respective local thermosensitivities in the hypothalamus, spinal cord and skin.

Thiols, Thiol Depletion, and Thermosensitivity

Radiation Research, 1983
Hyperthermia sensitization or tolerance is subject to cellular events that may occur at membrane, nuclear, and cytoplasmic sites. We have studied the effects of elevated temperatures on the oxidative-reductive state of the cell by measuring and altering glutathione (GSH) concentrations. GSH plays a pivotal role in maintaining the overall cellular redox

Sulfhydryl Compounds as Thermosensitizers

1988
The cytotoxic effects of a number of widely used chemotherapeutic agents have been reported to be enhanced by heat (Hahn 1979; Hahn and Li 1982). The exact mechanism of this enhancement is not fully understood and might differ with the various compounds. Thermosensitization by sulfhydryl compounds in vitro has been observed by Kapp and Hahn (1979).

Thermosensitive and biocompatible cyclotriphosphazene micelles

Journal of Controlled Release, 2007
A new class of thermosensitive micellar cyclotriphosphazenes has been synthesized by stepwise nucleophilic substitutions of hexachlorocyclotriphosphazene with a hydrophilic methoxy poly(ethylene glycol) (MPEG) and a hydrophobic oligopeptide selected from tetra- to hexapeptides, and characterized by means of multinuclear ((1)H, (31)P) NMR spectroscopy ...

In vitro thermosensitivity of the midline thalamus

Brain Research, 1995
This study compared the thermosensitivity and spontaneous activity of thalamic midline neurons with those of neurons in areas widely regarded to be involved in thermoregulation (preoptic/anterior hypothalamus and posterior hypothalamus). In vitro single unit recordings were made from neurons within the thalamic midline nuclei, the preoptic/anterior ...

Modification of Intracellular pH and Thermosensitivity

Radiation Research, 1992
The effects of amiloride (an inhibitor of Na+/H+ antiport), DIDS (an inhibitor of Na(+)-coupled and Na(+)-independent HCO3-/Cl- exchange) and nigericin (K+/H+ ionophore) alone and in various combinations on the intracellular pH (pHi) and thermosensitivity of SCK tumor cells were studied.

Thermosensitive midbrain neurons in the cat

Brain Research, 1977
Responses of single neurons in the midbrain of cats anesthetized with chloral hydrate were studied during manipulations of midbrain temperature produced with a bilateral water-perfused thermode. Temperatures of the thermodes and the anterior hypothalamus were monitored while single neuron activity was recorded between the thermodes and correlated with ...

Thermosensitive hydrogels for drug delivery

Expert Opinion on Drug Delivery, 2011
Controlled drug delivery has been widely applied in areas such as cancer therapy and tissue regeneration. Thermosensitive hydrogel-based drug delivery systems have increasingly attracted the attention of the drug delivery community, as the drugs can be readily encapsulated and released by the hydrogels.Thermosensitive hydrogels that can serve as drug ...
