Since the discovery in the early 1980s that 1-octen-3-ol, isolated from oxen breath, attracts tsetse fly, there has been growing interest in exploring the use of this semiochemical as a possible generic lure for trapping host-seeking mosquitoes. Intriguingly, traps baited with 1-octen-3-ol captured significantly more females of the malaria mosquito, Anopheles gambiae, and the yellow fever mosqu...

Essential oil of Baru Cina leaves (Artemisia vulgaris L.) has been successfully isolated by hydrodistillation method using the Stahl apparatus. were for ± 6 hours to produce essential amount 0.39 % (v/b). The obtained from was characterized GC-MS spectroscopy. analysis results showed that there 29 compounds and main identified as many 14 compounds, such Alpha-Pinene (0.33%), 1,8-Cineol (1.96% )...

The monohydroxy carotenoid from the moth Cerura vinula has been shown to be /?,/?-caroten-2-ol on the basis of electronic, infrared, proton magnetic-resonance, and mass spectra. On acid treat­ ment in the presence of molecular oxygen this carotenoid is dehydrogenated to 4',5-retro-ß,ßcaroten-2-one. The identification of /?„/?-caroten-2-ol by its retro product, its time course of acetylation, an...

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...
