Thermosensitive polymer-modified liposomes
Advanced Drug Delivery Reviews, 2001Temperature-sensitive liposomes are considered to be a promising tool to achieve site-specific delivery of drugs. These liposomes have been prepared using lipids whose membranes undergo a gel-to-liquid crystalline phase transition a few degrees above physiological temperature. However, recently, temperature-sensitization of liposomes has been attempted

Intra-abdominal thermosensitivity in the rabbit as compared with spinal thermosensitivity
Pfl�gers Archiv European Journal of Physiology, 1973In rabbits, intra-abdominal temperature sensors of the dorsal wall of the abdominal cavity were selectively stimulated by means of thermodes perfused with water of temperatures ranging from 12–50°C. Respiratory acceleration and vasodilatation of the skin could be elicited as thermoregulatory responses by intraabdominal warming.

Thermosensitive Gold Nanoparticles
Journal of the American Chemical Society, 2004Thermosensitive gold nanoparticles were fabricated by conjugating Au with a thiol-terminated poly(N-isopropylacrylamide) or PPA; this polymer stabilizer exhibits a temperature transition while undergoing a hydrophilic to hydrophobic transformation. The introduction of PPA onto gold nanoparticles has sensitized Au nanoparticles with unique temperature ...

Nonpolymeric Thermosensitive Benzenetricarboxamides
Langmuir, 2010A new class of nonpolymeric thermosensitive materials based on the benzene-1,3,5-tricarboxamide (BTC) structural platform are described. We observed that the benzocrown ether-substituted BTC derivatives undergo an unusual temperature-dependent reversible solubility change in aqueous solution.

Thermoreceptors and thermosensitive afferents
Neuroscience & Biobehavioral Reviews, 2009Cutaneous thermosensation plays an important role in thermal regulation and detection of potentially harmful thermal stimuli. Multiple classes of primary afferents are responsive to thermal stimuli. Afferent nerve fibers mediating the sensation of non-painful warmth or cold seem adapted to convey thermal information over a particular temperature range.

Thermosensitive Biodegradable Polydepsipeptide
Macromolecular Bioscience, 2005AbstractSummary: A poly(N‐isopropylacrylamide) (PNIPAAm)‐like biodegradable thermosensitive polydepsipeptide, poly[Glc‐Asn(N‐isopropyl)], was synthesized by introducing an isopropyl amide group into poly[Glc‐Asn]. Poly[Glc‐Asn(N‐isopropyl)] was degraded in vitro by cleavage of the ester bonds in the main chain in water at room temperature.

Thermosensitive lichen amyloidosis
International Journal of Dermatology, 2004AbstractBackground A 26‐year‐old male presented with a 3‐year history of lichen amyloidosis. On examination, there was a pigmented papular eruption with a ripple pattern affecting the limbs and trunk but sparing the axillae, antecubital and popliteal fossae, central chest, neck and face.

Journal of Colloid and Interface Science, 2008
We demonstrate an extension of a UV-Vis spectroscopy method to determine the phase boundaries for thermosensitive colloids as an alternative to the time-consuming sedimentation method. The Bragg attenuation peak from colloidal crystallites was monitored during the quasi-equilibrium colloidal crystal melting.

Latencies in a thermosensitive pathway
Experientia, 1974Mittels photographischem Blitzlicht wurden die Warmerezeptoren des Ratten-Hodensacks erwarmt und die Nervenleitgeschwindigkeit in der afferenten Bahn bis zum dorsalen Horn und dem ventrobasalen Thalamus gemessen. Bei einer Nervenleitgeschwindigkeit von 0.4 m/sec erwies sich der ganze nervose Weg als aus marklosen C-Fasern bestehend.
