Steroid-8-ene isomerase that catalyzes isomerization of delta 8- to delta 7-sterols has been solubilized from rat liver microsomes with a mixture of two detergents, octylglucoside and sodium taurodeoxycholic acid. During a 40-fold enrichment of the solubilized enzyme, other enzymes of cholesterol biosynthesis, endogenous lipids, and electron carriers are removed. A comparison of properties of t...

1-Octen-3-ol is a kairomone for many haematophagous insects including mosquitoes. Numerous studies have examined the effects of racemic 1-octen-3-ol; however, few studies have investigated the role of individual enantiomers in relation to mosquito attraction. In the present study, we investigated the behavioural and electrophysiological responses of two mosquito species, Aedes aegypti and Culex...

We identified a novel neuroprotective compound, 1-methoxyoctadecan-1-ol, from Uncaria sinensis (Oliv.) Havil and investigated its effects and mechanisms in primary cortical neurons and in a photothrombotic ischemic model. In primary rat cortical neurons against glutamate-induced neurotoxicity, pretreatment with 1-methoxyoctadecan-1-ol resulted in significantly reduced neuronal death in a dose-d...

as mystics make relationships to god in different ways, they consider different aspects of his (god) characters. in this article, it is tried to verify distinct ways of mystics, relation to allah according to their conscience sentience (receipt) of gods traits (specifications). the main purpose of this article is surveying mystics’s relations and their inference to allah based on holly quran an...

Ancistrotermes dimorphus is a common Macrotermitinae representative, facultative inquiline by its life-style, occurring in South-East China. Sex pheromone is used for couple formation and maintenance, and it is produced by and released from the female sternal gland and is highly attractive to males. Based on our combined behavioral, chemical and electrophysiological analyses, we identified (3Z,...

1. The metabolism of [4-(14)C]pregnenolone to androst-16-enes has been studied in short-term incubations of boar testis tissue. With fresh tissue androsta-5,16-dien-3beta-ol (8%) and 5alpha-androst-16-en-3beta-ol (2%) were formed. Tissue that had been stored at -20 degrees C was still capable of metabolizing pregnenolone to androsta-5,16-dien-3beta-ol. 2. NADPH was essential for the formation o...

The biotransformation of partheniol by the fungus Calonectria decora ATCC 14767, produced six metabolites. These metabolites are; aromadendr-1(10)-en-8alpha -ol; 5(9),6-tricyclohumul-1(10)-en-8alpha-ol; 4,15-didehydro-6-bicyclohumulan-8a,10alpha-diol; 5(9),6-tricyclohumulan-4a,8alpha-diol; maalian-la,8alpha-diol and 14-epi-1(4)-epoxymaalian-8alpha-ol. The identities of these metabolites were es...

An homogenate of rat liver which was capable of converting 2-3H-lanosta-8,24-dien-3fl-ol to 2-3H-cholest-5-en-3/3-ol failed to convert 2-3H-9, 19-cyclolanost-24-en-30-01 to 2-3Hcholest-5-en-3/3-01. However, both substrates underwent reduction at C-24,25. 2-3H-9, 19-Cyclolanost-24-en-3/?-01 was not converted to 2-3H-lanosta-8,24-dien-3P-ol. Both the presence and biosynthesis (from 2-14C-mevalona...

The vapor-phase dehydration of 1,3-butanediol (1,3-BDO) to produce 1,3-butadiene (BD) was investigated over yttrium zirconate, Y2Zr2O7, which prepared through a hydrothermal aging process. 1,3-BDO initially dehydrated three unsaturated alcohols, namely 3-buten-2-ol, 3-buten-1-ol, and 2-buten-1-ol, followed by the further BD. catalytic activity Y2Zr2O7 strongly dependent on calcination temperatu...

Terpinen-4-ol is a monoterpenoid alcohol and component of the essential oils of several aromatic plants. Similarly to terpinen-4-ol, other monoterpenoid alcohols have shown anticonvulsant activity in convulsion animal models. The present study aimed to investigate the anticonvulsant activity of terpinen-4-ol. Treatment of mice with terpinen-4-ol (200 mg/kg) caused a significant decrease in the ...
