The COMT Val Met polymorphism does not modulate the after-effect of tDCS on working memory.

Transcranial direct current stimulation (tDCS) can alter cortical excitability, neural plasticity, and cognitive-behavioral performance; however, its effects are known to vary across studies. A partial account of this variability relates to individual differences in dopamine function. Indeed, dopaminergic manipulations alter the physiological and cognitive-behavioral effects of tDCS, and gene polymorphisms related to dopamine have predicted individual response to online tDCS (i.

[The cytochemical indicators in patients with II stage hypertension disease and isolated traumas of long tubular bones of lower extremities].

The cytochemical indicators of neutrophils of peripheral blood were analyzed in 30 patients with hypertension disease and isolated traumas of long tubular bones of lower extremities. It is established that in such patients the variations of microbicidal neutrophils systems manifest in the increase of content of cationic proteins and non-significant decrease of myeloperoxidase activity. This is one of mechanisms of immunity support during first 48 hours after trauma.

[Characteristics of mycobacteria isolated from man, animals and environmental objects].

The paper deals with the identification results of mycobacteria isolated from man, animals and environmental objects. Mycobacterium bovis had a high resistance towards all trial drugs. Nevertheless, the representatives of atypical mycobacteria were resistant to streptomycin, isoniazid and PAS.

[Immobilization of aspergillus oryzae aminopeptidase on organic and inorganic carriers].

The process of Asp. oryzae aminopeptidase immobilization on organic (AE-cellulose, sepharose 4B, Sephadex G-200) and inorganic (SCh-2, SCh-3 sylochromes and KCK N 1 silicagel) carriers was studied. Aminopeptidase immobilized on Sephadex G-200 contains the largest amount of protein (80 mg per 1 g of carrier) and is the most active of all other preparations.
