Microbial transformations of racemic 7-methoxyflavanone using strains of the genus Aspergillus (A. niger KB, A. ochraceus 456) and the strain Penicillium chermesinum 113 were described. The strain A. niger KB catalysed carbonyl group reduction, leading to (±)-2,4-cis-7-methoxyflavan-4-ol. Biotransformation with the help of A. ochraceus 456 gave two products: (+)-2,4-trans-7-methoxyflavan-4-ol a...

Gravity models are widely used to explain patterns of trade. However, two stylized features of trade data, sample selection and heteroskedasticity, challenge the estimation of gravity models. We propose a Two-Step Method of Moments (TS-MM) estimator that deals with both issues. The Monte-Carlo experiments show that the TS-MM estimates are resistant to various combinations of sample selection an...

Medicinal mushrooms have an established history of use in traditional therapies. Modern clinical practice in Asian countries continues to rely on mushroom derived bioactive compounds. Medicinal effects have been demonstrated for many traditionally used mushrooms. The use of mushrooms extract and their bioactive compounds as antioxidants is becoming increasingly popular and could bring diverse p...
