The authors survey and analyze the main concepts and postulates of the quantum computing model, efficient quantum algorithms, and recent results, capabilities, and prospects in constructing a scalable quantum computer. A certain class of algebraic problems in the quantum computing model is considered for which there exists an efficient quantum solution algorithm. A detailed analysis of available quantum computer implementations was carried out, and it is shown that sufficient progress has not yet been made in constructing a scalable quantum computing device; nevertheless, most researchers expect that a full-fledged quantum computer will be created in the next 10–15 years.

A method for endogenous formaldehyde (FA) level evaluation has been worked out. The method involves the administration of dimedone, which forms the stable complex with FA, and the determination of formaldimedone concentration in biological samples by the fluorescence approach. The method was tested on rat's models of FA metabolism modulation. Animals received FA (10 mg/kg); or methylamine - substrate of FA-generating enzyme SSAO, (250 mg/kg); or semicarbazide - SSAO inhibitor, (200 mg/kg). Concentration of FA bound with dimedone in the liver tissue were, correspondingly: 7.5 +/- 1.5 mkg/kg; 5.4 +/- 0.9 mkg/kg; 2.4 +/- 0.7 mkg/kg; control - 4.2 +/- 1.4 mkg/kg. Obtained data indicate, that the elaborated method gives reliable information about FA level.
