    В статье исследуется влияние степени восстановления магнитной энергии рабочих зазоров импульсного линейного электромагнитного двигателя на механическую работу без учета насыщения его магнитной системы для нескольких энергетических режимов. Определены режимы такого двигателя с наибольшей механической работой.The article explores the influence of the degree of recovery of magnetic energy working clearances pulsed electromagnetic linear motor for mechanical work without considering his saturation magnetic system for multiple energy regimes. Such modes are defined by the engine with the highest mechanical work

    Spontaneous rearrangements in RNA sequences

    AbstractThe ability of RNAs to spontaneously rearrange their sequences under physiological conditions is demonstrated using the molecular colony technique, which allows single RNA molecules to be detected provided that they are amplifiable by the replicase of bacteriophage Qβ. The rearrangements are Mg2+-dependent, sequence-non-specific, and occur both in trans and in cis at a rate of 10−9 h−1 per site. The results suggest that the mechanism of spontaneous RNA rearrangements differs from the transesterification reactions earlier observed in the presence of Qβ replicase, and have a number of biologically important implications

    The algorithm of differential diagnosis of the two most common genetic variants the limb-girdle muscular dystrophy (LGMD2A and DMD), developed on the basis of a comprehensive survey of 85 patients with a diagnosis specification using techniques of DNA analysis. It is shown that the accurate diagnosis of LGMD genetic types should be based on the results of the clinical and genealogical, biochemical and molecular genetic analysis. The proposed algorithm will significantly reduces the economic and time costs with expensive DNA testing.Предложен алгоритм дифференциальной диагностики 2 наиболее распространенных генетических вариантов поясно-конечностных мышечных дистрофий (ПКМД): ПКМД типа 2А и типа ПКМД Дюшенна/Беккера, разработанный на основании комплексного обследования 85 больных с уточненным диагнозом с использованием методов ДНК-анализа. Показано, что точная диагностика генетического варианта ПКМД должна базироваться на результатах проведения клинико-генеалогического, биохимического, молекулярно-генетического анализа. Предложенный алгоритм позволит значительно снизить экономические и временные затраты при проведении дорогостоящих ДНК-анализов
