Thermosensitivity of pollen: a molecular perspective
Plant Cell Reports, 2023A current trend in climate comprises adverse weather anomalies with more frequent and intense temperature events. Heatwaves are a serious threat to global food security because of the susceptibility of crop plants to high temperatures. Among various developmental stages of plants, even a slight rise in temperature during reproductive development proves

Thermosensitive Micropatterned Substrates
2014We describe the design of micropatterned surfaces for single cell studies, based on photo-patterned thermoresponsive polymer brushes. Such surfaces allow for spatially controlled cell adhesion at 37°CC and thermal harvesting of the studied cells at T

A comparison between total body thermosensitivity and local thermosensitivity in mammals and birds
Pfl�gers Archiv European Journal of Physiology, 1984We 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, 1983Hyperthermia 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

Thermosensitive and biocompatible cyclotriphosphazene micelles
Journal of Controlled Release, 2007A 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 ...

Hypothalamic Thermosensitivity in Mammals
1978Hypothalamic 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 ...

In vitro thermosensitivity of the midline thalamus
Brain Research, 1995This 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 ...

Sulfhydryl Compounds as Thermosensitizers
1988The 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).

Modification of Intracellular pH and Thermosensitivity
Radiation Research, 1992The 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, 1977Responses 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 ...
