Cognitive Disorders in Patients with Parkinson\u27s Disease on the Background of Autoimmune Pathology

Parkinson\u27s disease (PD) is a progressive neurodegenerative disease characterized by the predominantly dopaminergic neuronal black matter degeneration. The multicentre study of PRIAMO (PaRkinson & non Motor symptom) showed that in 98.6 % of cases, non-motor symptoms (NMS) were observed in patients with PD. Cognitive impairment is one of the most common NMS PD. According to these studies, cognitive dysfunction develops in most patients at an early stage of the disease, with mild to moderate cognitive impairment. In the later stages of the disease, dementia occurs in 80 % of patients with PD. Aim of the research. To study the peculiarities of cognitive impairment in patients with PD and autoimmune thyroiditis (AIT), their association with motor and non-motor disorders, and to assess the impact on the quality of life of patients.Materials and methods of the research. 109 patients with PD aged 47 to 75 years were examined. The main group consisted of patients with IA and IB subgroups, control – IIA and IIB subgroups. General clinical and neurological examinations, evaluation of motor functions by the Unified Parkinson\u27s disease Rating Scale (UPDRS), neuropsychological testing (MMSE, MoCA, FAB, BDI), Hamilton\u27s Alert Scale (HARS), scale used for assessing autonomic disorders in patients with PD and Parkinson\u27s disease questionnaire (PDQ-39), statistical analysis using the "Statistica 6.0" program.Results. Neuropsychological testing showed that MMSE, MoCA, and FAB obtained from patients with PD and AIT are lower compared to patients with PD. Analyzing the indicators of MMSE, FAB, and MoCA scales in dynamics, a statistically significant difference was found in subgroups of IB and IIB; in subgroups of IA and IIA – was not observed. During the analysis of the results of the neuropsychological testing, no association was found at the statistically significant level in the subgroups of IA and IB between the duration of the disease and MMSE, MoCA, and FAB scales. In the IA subgroup, in the initial review, feedback was observed on a statistically significant level of average strength between the level of anxiety and the indicator of the MMSE scale, an indicator of the MoCA scale. In the IA subgroup, there was no relationship at the statistically significant level between the indicators of neuropsychological testing (MMSE, MoCA, FAB) and motor and non-motor manifestations (depression, vegetative disorders). There was a connection at a statistically significant level between the indicators of neuropsychological testing (MMSE, MoCA, FAB) and motor and non-motor manifestations of PD in patients who received anti-parkinsonian therapy for a long period of time. The negative influence of the level of cognitive impairments on the quality of life of patients with PD and AIT was revealed, indicating the high medical and social significance of these violations.Conclusions. Neuropsychological testing showed that MMSE, MoCA, FAB scores in patients with PD and AIT (IB subgroup) were lower compared to patients with PD (IIB subgroup). There was a connection at a statistically significant level between the indicators of neuropsychological testing (MMSE, MoCA, FAB) and motor and non-motor manifestations of PD in patients who received anti-parkinsonian therapy for a long period of time.

Thermal and luminescent properties of M2Zn(VO3) 4 (M = Rb, Cs)

We have developed processes for the synthesis of the Rb 2Zn(VO3)4 and Cs2Zn(VO 3)4 tetrametavanadates. Rb2Zn(VO 3)4 has been prepared by solid-state reaction (350 C) between presynthesized RbVO3 and ZnV2O6 powders, and Cs2Zn(VO3)4 has been prepared by the Pechini method (sol-gel process). Both metavanadates crystallize in monoclinic symmetry (sp. gr. P21/m). Thermochemical characterization results demonstrate that the vanadates undergo complex transformations during heating to 450 C and subsequent cooling. As a result, the materials are in a nonequilibrium state at room temperature and consist of both the parent double metavanadates and their peritectic decomposition products. We believe that the formation of the structure of the M2Zn(VO3)4 compounds from their melts is a kinetically hindered process. These compounds are structurally stable only at temperatures below 369 (Rb2Zn(VO 3)4) or 420 C (Cs2Zn(VO3) 4). We have measured for the first time the diffuse reflectance and photoluminescence excitation spectra of the two tetrametavanadates in their emission range and their photoluminescence spectra at various excitation wavelengths and determined their chromaticity coordinates. Their X-ray luminescence and scintillation decay characteristics have been determined for the first time under pulsed electron beam excitation. The electron excitation dissipation processes in the cesium and rubidium compounds are shown to be similar. We discuss the origin of the emission bands in the mixed vanadates and their potential application areas. © 2013 Pleiades Publishing, Ltd

Transcription Impacts the Efficiency of mRNA Translation via Co-transcriptional N6-adenosine Methylation

Transcription and translation are two main pillars of gene expression. Due to the different timings, spots of action, and mechanisms of regulation, these processes are mainly regarded as distinct and generally uncoupled, despite serving a common purpose. Here, we sought for a possible connection between transcription and translation. Employing an unbiased screen of multiple human promoters, we identified a positive effect of TATA box on translation and a general coupling between mRNA expression and translational efficiency. Using a CRISPR-Cas9-mediated approach, genome-wide analyses, and in vitro experiments, we show that the rate of transcription regulates the efficiency of translation. Furthermore, we demonstrate that m6A modification of mRNAs is co-transcriptional and depends upon the dynamics of the transcribing RNAPII. Suboptimal transcription rates lead to elevated m6A content, which may result in reduced translation. This study uncovers a general and widespread link between transcription and translation that is governed by epigenetic modification of mRNAs

The Voice of Trailing Women in the Decision to Relocate: Is it Really a Choice?

The reasons for migration among highly skilled couples are economic as well as noneconomic. However, our understanding of the motivations of trailing wives remains somewhat limited, especially given their loss of personal, professional, and social resources during the relocation. This chapter explores the motivations of women to relocate for their husband’s work. It examines how gender ideologies weave with the decision to relocate, and how women’s considerations and preferences are taken into account during this process. This study included depth interviews with 12 trailing mothers in the Netherlands and in the United States during 2015–2016. Interviews were performed face-to-face or by video chat. The study used an interpretative phenomenological analysis (IPA). Narratives analyses revealed that most trailing wives exerted very limited agency during the decision process and felt that they do not have any realistic alternatives to relocation. This powerlessness was imposed by gender-role ideologies that portray women as the primary care provider and men as the primary breadwinner. Thus, women’s motivations to go overseas were primarily centered on family benefits, such as improving the family’s financial status or supporting their husband’s career. These findings suggest that societal factors, mainly gender, significantly diminish the actual choice options available to trailing wives

Old Water Becoming New Again: Reuse of Treated Wastewater Effluent in Texas

The reuse of treated wastewater effluent for municipal supply is not a new idea in Texas, having been contemplated for at least sixty years. However, its importance has grown in recent decades as traditional surface water sources have become fully subscribed. Reuse is recognized as a significant source of future supply for Texas in the 2017 Texas State Water Plan.1 The law related to reuse is, however, still very much a developing subject. Recent administrative actions and judicial decisions have better defined the contours of the entitlements necessary to reuse effluent discharged to state-owned water courses.2 In the midst of this continued legal evolution, water suppliers in the Trinity River basin are actively implementing reuse projects using the river as a conveyance for the indirect reuse of discharged effluent

2-limited broadcast domination in grid graphs

We establish upper and lower bounds for the 2-limited broadcast domination number of various grid graphs, in particular the Cartesian product of two paths, a path and a cycle, and two cycles. The upper bounds are derived by explicit constructions. The lower bounds are obtained via linear programming duality by finding lower bounds for the fractional 2-limited multipacking numbers of these graphs
