    Intellectual decline in patients with schizophrenia with comorbid type ii diabetes mellitus and alcoholism

    Get PDF
    Comorbid conditions in general psychopathological practice need equally research in the field of psychiatry and narcology, as well as the development of issues of social practice in relation to mental patients. There is an opinion that comorbid mental pathologies are even more common than “pure” forms of diseases. In most cases of comorbid conditions, the medical community increasingly encounters clinical situations where “classic” symptoms and syndromes are deformed, mutually intertwined and, superimposed on the actual social situation of the patient, acquire an “unreal fancy character”.Schizophrenia remains one of the most urgent problems at the stage of modern psychiatry formation. Up to date there are 1.1% of men and 1.9% of women in the general population of patients. Schizophrenic spectrum disorders are often combined with a number of chronic pathologies that increase the negative impact on the neuro-cognitive sphere of a person. One of the main problems of modern urbanized society is type II diabetes and alcoholism. By increasing the negative impact on a person’s cognitive abilities, they accelerate the process of disintegration of personality and its social functioning. The intellectual level of patients with those chronic diseases that require patients to actively and consciously participate in the treatment process and social functioning can significantly affect the patient’s ability to learn, independently manage the disease, establish a high level of compliance and, as a result, the effectiveness of therapy. An attentive study of the issue of the state of intelligence of patients with comorbid pathology will lead to an improvement in the patient’s social adaptation, a more careful attitude to their somatic health and reduce the risk of disability of the able-bodied population

    The trigonal polymorph of strontium tetra­borate, β-SrB4O7

    Get PDF
    The asymmetric unit of the title compound, β-SrB4O7, contains five Sr atoms (three located on a threefold rotation axis), twelve B and 21 O atoms. The structure is made up from BO3 triangles and BO4 tetra­hedra in a 1:1 ratio. Pairs of BO3 triangles are linked to BO4 tetra­hedra via common corners, forming chains. These chains are further linked to adjacent chains through corner-sharing, leading to a three-dimensional framework with channels running parallel to [001]. The Sr2+ ions reside in the channels and exhibit strongly distorted polyhedra The density of the β-polymorph is considerably lower than that of α-SrB4O7, which is constructed solely from BO4 tetra­hedra

    Objective to define the main elements of provocative behavior of a victim and its difference from the provocation of a crime. Methods dialectic approach to the study of social phenomena and historical and comparativelegal methods for the study of legal reality. Results scientific grounding of theoreticallegal bases of the ldquoprovocationrdquo institution and formulating proposals for improving its legislative regulation and increasing the efficiency of its law enforcement. Scientific novelty the article presents the author39s classification of the types and forms of provocative activity in the norms of both the General and the Specific parts. Practical value summarizing and analysis of the modern empirical data on the practice of implementation of the norms containing the features of provocation and elaboration of organizational and methodological recommendations based on the authorrsquos research. nbs

    В данной работе исследованы частицы со структурой металлическое ядро (магний) – металлическая оболочка (никель), полученные в металлсодержащей ВЧ плазме дугового разряда. Методами рентгенофазового анализа, рентгенофлуоресцентного анализ, сканирующей электронной микроскопии показано, что частицы имеют сплошную никелевую оболочку, что также косвенно подтверждается сравнением результатов гидрирования частиц Mg и Mg@Ni. С помощью измерений объёмной намагниченности установлено, что размер наибольшая часть частиц имеет толщину оболочек не более 22 нм

    Iridium Catalysts for Acceptorless Dehydrogenation of Alcohols to Carboxylic Acids: Scope and Mechanism

    We introduce iridium-based conditions for the conversion of primary alcohols to potassium carboxylates (or carboxylic acids) in the presence of potassium hydroxide and either [Ir­(2-PyCH<sub>2</sub>(C<sub>4</sub>H<sub>5</sub>N<sub>2</sub>))­(COD)]­OTf (<b>1</b>) or [Ir­(2-PyCH<sub>2</sub>PBu<sub>2</sub><sup>t</sup>)­(COD)]­OTf (<b>2</b>). The method provides both aliphatic and benzylic carboxylates in high yield and with outstanding functional group tolerance. We illustrate the application of this method to a diverse variety of primary alcohols, including those involving heterocycles and even free amines. Complex <b>2</b> reacts with alcohols to form the crystallographically characterized catalytic intermediates [IrH­(η<sup>1</sup>,η<sup>3</sup>-C<sub>8</sub>H<sub>12</sub>)­(2-PyCH<sub>2</sub>P<sup>t</sup>Bu<sub>2</sub>)] (<b>2a</b>) and [Ir<sub>2</sub>H<sub>3</sub>(CO)­(2-PyCH<sub>2</sub>P<sup>t</sup>Bu<sub>2</sub>)­{μ-(C<sub>5</sub>H<sub>3</sub>N)­CH<sub>2</sub>P<sup>t</sup>Bu<sub>2</sub>}] (<b>2c</b>). The unexpected similarities in reactivities of <b>1</b> and <b>2</b> in this reaction, along with synthetic studies on several of our iridium intermediates, enable us to form a general proposal of the mechanisms of catalyst activation that govern the disparate reactivities of <b>1</b> and <b>2</b>, respectively, in glycerol and formic acid dehydrogenation. Moreover, careful analysis of the organic intermediates in the oxidation sequence enable new insights into the role of Tishchenko and Cannizzaro reactions in the overall oxidation
