Preliminary investigations have shown that Clostridium acetobutylicum and related butyric-acid butyl-alcohol bacteria, fail to develop in a synthetic medium containing only ammonium sulphate, inorganic salts and glucose. These results suggest that perhaps the organisms require complex nitrogen compounds or some specific growth factor. Wood, Tatum and Peterson (1937), Wood, Andersen and Werkman ...

The selective removal of acidic phosphoproteins from the 80 S rat liver ribosome was accomplished by successive alcohol extractions at low salt concentration. The resulting core ribosomes lost over 90% of their translation activity and were unable to support the elongation factor 2 GTPase reaction. Both activities were partially restored when the dialyzed extracts were added back to the core ri...

Previous reports have claimed Adriamycin to be cytotoxic to cultured tumor cells when the drug is covalently immobilized on a solid support, thus suggesting a cell surface mechanism of action for the drug. Although these previous reports attempted to rule out released drug or endocytosis of drug-support particles as alternative explanations for the observed cytotoxicity, a more thorough analysi...

BACKGROUND Factors associated with the development of hypertension can be categorized into modifiable and non-modifiable risk factors. The modifiable risk factors include obesity, physical inactivity, high salt diet, smoking alcohol consumption and others. AIM This study was aimed to determine the prevalence of modifiable risk factors of hypertension in a rural community; Oghara and to ascert...

In the present contribution, the pre-structuring of binary mixtures of hydrotropes and H2O is linked to the solubilisation of poorly water miscible compounds. We have chosen a series of short-chain alcohols as hydrotropes and benzyl alcohol, limonene and a hydrophobic azo-dye (Disperse Red 13) as organic compounds to be dissolved. A very weak pre-structuring is found for ethanol/H2O and 2-propa...

Photochromic tris(phenylisoxazolyl)benzene 1 and bispyridine derivatives 2a–e were mixed in a certain ratio to generate stable gels in benzyl alcohol, 4-methoxybenzyl alcohol, and aniline. Supramolecular assembly of 1 in solution was confirmed by 1H NMR study. The Tgel value was saturated in a 2 : 3 ratio of 1 and 2c. The intermolecular hydrogen bonds OH···N and salt bridge O(−)···H(–)N(+) betw...

1. NADH2 prepared by enzymic reduction of pure NAD by the method of Rafter & Colowick (1957), and isolated as the sodium salt, gives higher maxrimum rates of reduction of acetaldehyde with liver alcohol dehydrogenase at pH 6 than a number of commercial preparations of high purity. Maximum values of 2-4 for the extinction ratio E260/E340 and 2% for the proportion of inactive material absorbing a...

An organism tentatively identified as Ralstonia eutropha was isolated from enrichment cultures containing tetrahydrofurfuryl alcohol (THFA) as the sole source of carbon and energy. The strain was able to tolerate up to 200 mM THFA in mineral salt medium. The degradation was initiated by an inducible ferricyanide-dependent alcohol dehydrogenase (ADH) which was detected in the soluble fraction of...

BACKGROUND Cardiovascular diseases (CVD) cause 1.8 million premature (<75 years) death annually in Europe. The majority of these deaths are preventable with the most efficient and cost-effective approach being on the population level. The aim of this position paper is to assist authorities in selecting the most adequate management strategies to prevent CVD. DESIGN AND METHODS Experts reviewed...
