Temperature-sensitive conduction failure at axon branch points
Journal of Neurophysiology, 1978 1. The propagation of action potentials through the branching regions of squid axons was examined experimentally and with computer simulations over a temperature range of 5-25 degrees C. 2. Above a critical ratio of postbranch to prebranch diameters, propagation of an action potential failed.

Low-melting-point substances are widely used to develop temperature-sensitive formulations. In this study, we focused on microcrystalline wax (MCW) as a low-melting-point substance. We evaluated the drug release behavior of wax matrix (WM) particles using various MCW under various temperature conditions.

Design of Temperature Sensitive Imprinted Polymer Hydrogels Based on Multiple‐Point Hydrogen Bonding
Macromolecular Bioscience, 2004AbstractSummary: Weakly cross‐linked temperature sensitive imprinted polymer hydrogels that recognize L‐pyroglutamic acid (Pga) molecules via multiple‐point hydrogen bonding were designed and synthesized. The amount of adsorption for Pga in imprinted hydrogels is 3–4 times higher than that in non‐imprinted hydrogels.

It was reported that wax matrix (WM) particles composed of low-melting-point microcrystalline wax showed unique release behaviors; the particles released only a small amount of the entrapped drug (non-diffusion-controlled release) at 37°C, whereas it showed comparatively fast drug release in a diffusion-controlled manner at 25°C. However, the mechanism
