Обследовали 100 больных с ожирением. Регулируемое бандажирование желудка (РБЖ) было выполнено 20 пациентам, рукавная резекция желудка (РРЖ)-40 больным и гастрошунтирование (ГШ)-40 больным. Контрольную группу составили 10 практически здоровых людей. В сыворотке крови иммуноферментным методом определяли концентрацию витаминов В 1 , В 2 , В 5 , В 6 , В 9 , В 12 , С, D, ниацина, биотина и ретинол-связывающего белка (РСБ) до операции и через 1 год после хирургического лечения. Выявлено значительное снижение витаминов С, В 6 , В 5 , D и РСБ как до, так и после бариатрических операций (БО). Более половины больных, перенесших РРЖ, имели также исходное снижение уровня ниацина. Через год после проведения БО (РБЖ, РРЖ, ГШ) число больных с дефицитом этих витаминов сохранялось прежним либо увеличивалось. ГШ не оказало существенного влияния на концентрацию фолиевой кислоты, витаминов В 2 , В 12 , В 1 и биотина. У un-ta.-Bulletin of North Caucasian federal university. 2014;1(40):83-85. 4.

Application of built-in self-test circuitries allows to improve the testing quality and reliability of complex analog and mixed-signal IC. BIST-circuitry is integrated to original circuit for the purpose of test signal generation, measurement of output responses and decision-making about correctness of circuit under test functioning. The most part of BIST-circuitries for analog and mixed-signal IC uses generators of sine wave or multifrequency wave for test signal generation, but it is not applicable for majority of practical implementations because of crucial increasing the chip area required for in-circuit realization of generator. The built-in self test circuitry for analog and mixed-signal IC based on reconfiguring original circuit in oscillator, which does not need the generator of input test signals, has been proposed. The principles of functioning and main components of the solution have been considered. The correct and incorrect behaviour of analog subcircuit is reflected in digital way by logical 0 or 1. The proposed circuitry provides possibility for joint testing analog and digital subcircuits of mixed-signal IC. The experimental results for benchmark second-order active filter demonstrating high efficiency of proposed BIST-circuitry have been represented. The fault coverage obtained by application of proposed BIST-circuitry is not inferior to results of other authors for the same filter, but measuring and estimation of output responses are performed in-circuit.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
