Municipal solid waste (MSW) compost contains a significant amount of humic substances. In this study, the compost consisted of residual MSW with the metal, plastic and glass removed. In order to enhance degradation processes and the degree of composting humification, complex microorganisms (Bacillus casei, Lactobacillus buchneri and Candida rugopelliculosa) and ligno-cellulolytic (Trichoderma a...

hantzsch 1 ,4- dihy&opyridines; are rapidly oxidized to the corresponding pyridine derivatives using zinc chlorochromate nonahydrate [zn(c1cro ) .9h o] in dichloromethane at room temperature. in addition to aromatization, no loss of the 4- substituent is observed

The effect of exemestane (6-methylenandrosta-1,4-diene-3,17-dione) 25 mg p.o. once daily on in vivo aromatization was studied in 10 postmenopausal women with advanced breast cancer. Aromatization was determined before treatment and after 6-8 weeks on therapy by administering a bolus injection of [3H]androstenedione (500 microCi) and [14C]estrone (5 microCi) followed by measurement of the isotop...

The addition of androstenedione and NADPH to human placental microsomes results in a marked increase in the rate of 0 2 and NADPH utilization concomitant with estrogen formation. Initially, 5 to 12 moles of O2 and an equivalent amount of NADPH are consumed per mole of estrogen formed, the ratio varying from one microsomal preparation to another. In the presence, however, of 10 to 20 mM KCN, 3 m...

A novel and synthetically efficient Cu(II) catalyzed oxidation-dipolar cycloaddition-aromatization cascade reaction has been developed for a "one-pot" synthesis of biologically important pyrrolo [2, 1-a] isoquinolines.

The steroidal regulation of vertebrate neuroanatomy and neurophysiology includes a seemingly unending list of brain areas, cellular structures and behaviors modulated by these hormones. Estrogens, in particular have emerged as potent neuromodulators, exerting a range of effects including neuroprotection and perhaps neural repair. In songbirds and mammals, the brain itself appears to be the site...

1. The fate of (-)-quinic acid has been investigated in 22 species of animals including man. 2. In man and three species of Old World monkeys, i.e. rhesus monkey, baboon and green monkey, oral quinic acid was extensively aromatized (20-60%) and excreted in the urine as hippuric acid, which was determined fluorimetrically. 3. In three species of New World monkeys, i.e. squirrel monkey, spider mo...
