Dhat syndrome is a culture-bound syndrome of South-East Asia, common in young men. However, similar entity has also been described in female patients who attribute their symptoms to nonpathological or physiological vaginal discharge. The current diagnostic system for psychiatric illnesses does not encompass Dhat syndrome in females, and so these group of patients receive alternative diagnoses such as somatoform disorder or depression. As a result of which the focus of unique Dhat syndrome-centered management gets weakened, affecting the clinical outcome...

Isobutanol is a valuable chemical and is considered a new generation biofuel. Construction of isobutanol synthesis pathways in bacteria is a hot topic in isobutanol production. Here, we show that an isobutanol synthesis pathway exists naturally in Klebsiella pneumoniae; however, this pathway is dormant in the wild-type bacterium. K. pneumoniae is a 2,3-butanediol producer, and the synthesis pathways of 2,3-butanediol, valine and isobutanol all start from condensation of two pyruvate molecules to yield α-acetolactate...

Criegee intermediates are produced in the ozonolysis of unsaturated hydrocarbons in the troposphere, and understanding their fate is a prerequisite to modeling climate-controlling atmospheric aerosol formation. Although some experimental and theoretical rate data are available, they are incomplete and partially inconsistent, and they do not cover the tropospheric temperature range. Here we report quantum chemical rate constants for the reactions of formaldehyde oxide (CH2OO) and acetaldehyde oxide (syn-CH3CHOO and anti-CH3CHOO) with H2O and for their unimolecular reactions...

UNLABELLED: Crude glycerol, the major by-product of biodiesel production, is an attractive bioprocessing feedstock owing to its abundance, low cost, and high degree of reduction. In line with the advent of the biodiesel industry, Clostridium pasteurianum has gained prominence as a result of its unique capacity to convert waste glycerol into n-butanol, a high-energy biofuel. However, no efforts have been directed at abolishing the production of 1,3-propanediol (1,3-PDO), the chief competing product of C...

Biodiesel can replace petroleum diesel as it is produced from animal fats and vegetable oils, and it produces about 10 % (w/w) glycerol, which is a promising new industrial microbial carbon, as a major by-product. One of the most potential applications of glycerol is its biotransformation to high value chemicals such as 1,3-propanediol (1,3-PD), dihydroxyacetone (DHA), succinic acid, etc., through microbial fermentation. Glycerol dehydratase, 1,3-propanediol dehydrogenase (1,3-propanediol-oxydoreductase), and glycerol dehydrogenase, which were encoded, respectively, by dhaB, dhaT, and dhaD and with DHA kinase are encompassed by the dha regulon, are the three key enzymes in glycerol bioconversion into 1,3-PD and DHA, and these are discussed in this review article...

Compared with chemical synthesis, fermentation has the advantage of mass production at low cost, and has been used in the production of various industrial chemicals. As a valuable organic compound, 1,3-propanediol (1,3-PDO) has numerous applications in the production of polymers, lubricants, cosmetics and medicines. Here, conversion of glycerol (a renewable substrate and waste from biodiesel production) to 1,3-PDO by E. coli bacterial strain carrying altered glycerol metabolic pathway was investigated. Two gene constructs containing the 1,3-PDO operon from Citrobacter freundii (pCF1 and pCF2) were used to transform the bacteria...
