Differential temperature dependence of taste nerve responses to various taste stimuli in dogs and rats.
The temperature dependence of the canine and rat chorda tympani nerve responses to various taste stimuli was examined. The temperature dependence greatly varied with species of stimuli. In the dog,Expand

Selective transport of the mulberry leaf urease from the midgut into the larval hemolymph of the silkworm, Bombyx mori.
Just before spinning, larvae of the silkworm, Bombyx mori, absorb intact urease of the host plant (mulberry leaf) from the midgut lumen into the hemolymph. In order to investigate whether theExpand

Rat taste nerve responses to salts carrying cations of large molecular size; are the taste responses to the salts induced by cation transport across apical membranes of taste cells?
1. The responses of rat chorda tympani nerve to various salts carrying cations of large molecular size which have small permeability were measured. 2. Salts carrying polyvalent cations such as Fe3+Expand

Synthesis and root growth-inhibitory activity of 2- and 3-(haloacetylamino)-3-(2-furyl)propanoic acids.
A convenient synthesis of 2- and 3-(chloroacetylamino)-3-(2-furyl)propanoic acids (6a, 7a) and their fluoro analogs were developed. Both 6a and 7a showed 51-55% root growth-inhibitory activityExpand
