Electrophysiological responses of olfactory receptor neurons in both male and female silkmoths (Bombyx mori) were investigated. In both sexes, the G-protein activator sodium fluoride and 1,2-dioctanoyl-sn-glycerol, a membrane-permeable analog of the protein kinase C activator diacylglycerol, elicited nerve impulse responses similar to those elicited by weak continuous stimulation with odorants....

A glycosidically bound fraction was prepared by adsorbing a 80% methanol extract from fresh rhizomes of ginger onto a column of Amberlite XAD-2 resin and successively eluting with ethyl acetate or methanol. Enzymatic hydrolysis of this fraction with an acetone powder prepared from fresh ginger and commercial glycosidase liberated such alcohols as geraniol, 2-heptanol, α-terpineol, nerol, linalo...

Background Double-wave reentry (DWR) can be a mechanism for acceleration of ventricular tachycardia (VT) with a large excitable gap (EG). The purpose of this study was to determine the effects of heptanol, class Ic, and class III drugs on the inducibility of DWR. Methods and Results In 11 Langendorff-perfused rabbit hearts, a thin ring of anisotropic left ventricular epicardium was created by a...

the enzymatic hydrolysis of meso-1,7-diacetoxy-2,6-dimethylheptane 5, prepared from 2,6-dimethylhepta-1,6-diene 6, gave the (2s,6r)-7-acetoxy-2,6-dimethyl-1-heptanol 1, which was transformed to the (2r,6r)-2,6,10-trimethyl-1-undecanol 7. in this manner, the c14 side chain of a-tocopherol was synthesized from 2,6-dimethylhepta-1,6-diene 6 in only 5 steps.

In vivo conjunctival epithelial healing in albino rabbits was investigated by light microscopy following both n-heptanol and trephined conjunctival wounding. Reepithelialization occurred faster following n-heptanol treatment (3 days) versus trephination (6-7 days). No goblet cells were present in the migrating epithelium during reepithelialization. After 1 day of wounding, goblet cells disappea...

The aim of the present study was to examine the hypothesis that acceleration of gap junction (GJ) closure during ischemia contributes to anti-infarct tolerance afforded by preconditioning (PC). First, the effects of PC on GJ communication during ischemia were assessed. Isolated buffer-perfused rabbit hearts were subjected to 5-min global ischemia with or without PC with two cycles of 5-min isch...

(S)-1-chloro-2-heptanol is an enantiopure chemical of great value that can synthesize Treprostinil for treating primary pulmonary hypertension. In this work, a new strain B-36, capable asymmetric reduction 1-chloro-2-heptanone to (S)-1-chloro-2-heptanol, was screened and identified as Curvularia hominis B-36 (CCTCC M 2017654) based on the morphological internally transcribed spacer (ITS) sequen...
