    Notch is a key player in various developmental processes during the embryonic stage as well as in regulating tissue homeostasis, cell differentiation, and stem cell maintenance in adult life. Activation of Notch signaling occurs following Notch receptor-ligand interaction and subsequent enzymatic proteolysis by the gamma-secretase complex, resulting in the cytoplasmic release of a Notch intracellular domain, which translocates to the nucleus to initiate the downstream transcriptional machinery. Notch activation and its aberrant signaling have been broadly linked to the pathogenesis of cancer and some chronic inflammatory diseases resulting in pathologic fibrotic processes. This review focuses on the molecular basis of Notch-induced signaling and its interaction with other pathways to identify therapeutic targets. We also highlight current efforts to pharmacologically intervene in Notch signaling and discuss promising ongoing experimental and clinical studies

    Объектом исследования является технология подготовки газа на Мыльджинском газоконденсатном месторождении. Цель данной работы – повышение эффективности использования метанола при подготовке газа методом низкотемпературной сепарации. С помощью моделирования в среде программы UniSim Design проведено исследование вариантов реализации рециркуляционной технологии использования метанола на УКПГ Мыльджинского месторождения. В результате исследования выявлено, что предлагаемый вариант рециркуляционной технологии позволяет сократить расход метанола на 110–140 кг/ч (40–45 %) за счет уменьшения уноса метанола с нестабильным конденсатом. Добавленная в технологическую схему установка ректификации метанола позволяет вернуть в технологический процесс еще 85–120 кг/ч метанола.The object of the study is the gas preparation technology at the Myldzhinskoye gas condensate field. The goal of this work is to increase the efficiency of methanol use in gas preparation by the low-temperature separation method. Using simulation in the UniSim Design program environment, a study was carried out on options for the implementation of the recirculation technology for the use of methanol at the gas treatment unit at the Myldzhinskoye field. As a result of the study, it was found that the proposed version of the recirculation technology reduces methanol consumption by 110–140 kg / h (40–45%) by reducing the entrainment of methanol with unstable condensate. The methanol rectification unit allows to return another 85–120 kg / h of methanol to the process
