Influence of Genetic Polymorphism on the Steady-State Concentration of Escitalopram in Patients with Recurrent Depressive Disorder.

Introduction: Escitalopram is commonly prescribed to patients with recurrent depressive disorder. Some of them do not show adequate response to treatment with escitalopram, while many of them experience adverse drug reactions.

Objective: The objective of our study was to evaluate the impact of -806C>T polymorphism of CYP2C19 (CYP2C19*17) on the concentration/dose ratio of escitalopram in patients with recurrent depressive disorder.

sp. nov., a thermophilic bacterium isolated from a high-temperature heavy oil reservoir in China.

A rod-shaped, spore-forming, thermophilic, chemoorganotrophic, aerobic or facultatively anaerobic bacterial strain, 1017, was isolated from production water sampled at the Dagang oilfield (PR China), and was characterized by using a polyphasic approach. The strain is capable of anaerobic glucose fermentation. Nitrate is reduced to nitrite.

Cohnella kolymensis sp. nov., a novel bacillus isolated from Siberian permafrost.

A facultative anaerobic, rod-shaped, endospore-forming and non-motile bacterium was isolated from permafrost sediment cores in the Kolyma lowland, Siberia, Russia. The permafrost isolate clustered with members of the genus Cohnella on the basis of 16S rRNA gene sequence analysis and showed the highest sequence similarity to Cohnella saccharovorans CJ22 (96.3 %), followed by Cohnella cellulosilytica FCN3-3 (96.

Rathayibacter oskolensis sp. nov., a novel actinobacterium from Androsace koso-poljanskii Ovcz. (Primulaceae) endemic to the Central Russian Upland.

A rod-shaped, non-endospore-forming and non-motile bacterium, strain DL-329, was isolated from the above-ground part of a plant, Androsace koso-poljanskii Ovcz. (Primulaceae), at the the State Natural Reserve 'Belogorie', Russia. On the basis of 16S rRNA gene sequence comparisons, the strain clustered with members of the genus Rathayibacter, showing the highest sequence similarity to Rathayibacter tritici (98.

Transformation of cellobiose during the interaction of cellobiose dehydrogenase and β-glucosidase of Cerrena unicolor.

This work investigated the regulatory role of the interaction between cellobiose dehydrogenase (CDH) and β-glucosidase (β-GLU) in the conversion of cellobiose into cellobionolactone or glucose in vitro. To study the regulation, the two enzymes were isolated from the culture medium of the fungus Cerrena unicolor grown on a medium with microcrystalline cellulose. The enzymes were obtained in an electrophoretically homogeneous state.
