A case of diabetic striatopathy due to uncontrolled type 2 diabetes
Authors: Cheneler M L , Qureshi K , Bahrami C 
Published: May 2024

Summary
Hemichorea–hemiballismus (HCHB) syndrome is a syndrome characterized by choreic movements which are irregular, nonrepetitive, and random movements, and ballismus which are spontaneous and violent movements. HCHB syndrome with a metabolic cause is a rare presentation that can be precipitated by uncontrolled diabetes. Presented here is a case of HCHB syndrome with right-sided neuroimaging findings and contralateral chorea due to uncontrolled type 2 diabetes mellitus. This patient was found to be obtunded with a blood glucose of greater than 500 mg/dL by EMS. After the administration of insulin, she was able to answer clarifying questions of noncompliance with her antihyperglycemic medications. She had a computed tomography without contrast of the head which showed hyperdense lesions in the right caudate nucleus and putamen consistent with HCHB syndrome. She was started on treatment for nonketotic hyperglycemia with insulin. As her mentation improved, she was able to cooperate with physical examination, which revealed irregular and violent movements in the left upper and lower extremities. Her hemichorea and hemiballismus improved with strict glycemic control, and she was able to be discharged to a skilled nursing facility for further rehabilitation. She would later have repeated hospitalizations for poor glycemic control, and repeat neuroimaging would reveal the resolution of hyperdensities after 4 months. HCHB syndrome due to uncontrolled diabetes has been termed diabetic striatopathy and is characterized by poor glycemic control, unilateral striatal hyperdensity on CT imaging, and contralateral choreic movements. Diabetic striatopathy remains a poorly understood disease, and the exact pathophysiologic mechanism has not been definitively elucidated.

Learning points

Diabetic striatopathy is a relatively new term for metabolic etiology of hemichorea–hemiballismus syndrome and was coined in 2009.

The triad for diabetic striatopathy is poor glycemic control, unilateral striatal hyperdensity on CT imaging, and contralateral choreic movements.

Multiple etiologies have been suggested for the cause of diabetic striatopathy including petechial hemorrhage, mineral deposition, myelin destruction, and infarction with reactive astrocytosis; however, the exact mechanism has yet to be determined.

Antidopaminergic medications may be used to control the choreic movements of diabetic striatopathy; however, the mainstay of treatment is glycemic control, often with insulin therapy.

AbstractThe manufacture of High-Performance Concrete (HPC) in bridge deck construction is part of an experimental framework that is also developing in the numerical domain to fill the existing gaps in understanding its behavior. However, the numerical modeling of HPC for bridge decks remains largely under-explored. It is precisely this gap that has sparked our interest in this research area, thus giving our work its innovative character.This study primarily aims to deepen the understanding of the behavior of HPC bridge decks while manufacturing an efficient and economical HPC using local materials possessing very high properties (mechanical, physical, elastic, durability, and implementation) and advanced numerical modeling. This modeling has enabled us to study the behavior of HPC bridge decks in relation to cracking through the Extended Finite Element Method (X-FEM), an innovative solution that enables the modeling of discontinuities without complicating the process. This has been confirmed by the quality of the results, which show an excellent correlation with experimental data, underscoring the accuracy of the modeling. These results also reveal that the use of HPC in bridge construction can significantly reduce degradation risks while enhancing their performance. Consequently, the adoption of HPC stands out as a beneficial strategy, not only to minimize bridge degradation but also to extend their durability.

Objective: To assess the financial situation of selected enterprises included in the WIG-food index in 2019–2021 from the point of view of the risk of bankruptcy.
Research Design & Methods: Four models of multidimensional discriminatory analysis were used to assess potential bankruptcy risk (Dorota Hadasik’s Model, Model Z6 INE PAN, Model Z7 INE PAN and the so-called Poznań Model). The entities selected for the study were all Polish companies traded on the WIG-food index in all quarters of the years 2019–2021. This condition had to be met due to the volatility of the composition of the WIG-food index on a quarterly basis (quarterly revision of the index portfolio). Two research hypotheses were formulated in the article. First, selected discriminant analysis models are an effective tool for assessing companies included in the WIG-food index for the risk of bankruptcy. And second, multidimensional discriminant analysis is a valuable and complementary tool to other methods of assessing the risk of company bankruptcy.
Findings: Companies included in the WIG-food index in 2019–2021 were in a very good financial situation with the exception of two companies, which faced the threat of bankruptcy in 2019: ZPC Otmuchów SA and Pamapol SA. Three of the models used indicated that the companies were moving in the wrong direction: Z6 INE PAN and Z7 INE PAN (ZPC Otmuchów SA) and the Poznań Model (Pamapol SA). This may suggest that these models were highly sensitive. Hadasik’s Model did not show any company to be at risk of bankruptcy in the analysed period.
Implications / Recommendations: One implication of the research is that the number of variables in discriminant analysis models does not work to exaggerate their efficiency. Two of the models used (Z6 INE PAN and Z7 INE PAN) returned similar results. This is mainly due to their being constructed similarly. Furthermore, none of the selected models showed high sensitivity to detecting the threat of bankruptcy among the companies analysed, though they could be used to faster warn about potential and actual problems.
Contribution: The research contributes to the development of knowledge on the use of discriminatory analysis models to assess bankruptcy risk of food industry enterprises in Poland.

The paper describes in detail the procedure for the preparation of a granular bulk NiMoW catalyst and a supported reference NiMo/Al2O3 catalyst. Mention is made of investigations of the supported and bulk catalysts by various physico-chemical methods (nitrogen adsorption-desorption method, X-ray photoelectron spectroscopy, TPD-NH3, HRTEM and X-ray diffraction analysis). The experiments to estimate catalytic activity and compare rate constant of hydrodesulfurization of dibenzothiophene using both catalysts have been carried out. It is shown that textural properties of the catalysts significantly differ. The supported catalyst has more developed specific surface area and pore volume than the bulk catalyst. TPD-NH3 showed an increased acidity of the supported catalyst in comparison the bulk catalyst. It is shown by the X-ray photoelectron spectroscopy method that in both samples Mo on the surface is present exclusively in the form of Mo4+ ion. However, the bulk catalyst differs from the supported catalyst in that it contains a larger amount of Ni as part of the active NiMo(W)S phase. The catalytic activity tests demonstrated that the bulk catalyst is more active at 240, 250 and 260°C, it is discovered that the rate constant in hydrodesulfurization of dibenzothiophene for the bulk NiMoW catalyst is twice higher at 240ºC than that of the supported NiMo/Al2O3 catalyst.

Aim. To assess the levels of matrix metalloproteinases (MMP), vascular endothelial growth factor (VEGF), and miRNA-34a expression in patients with ischemic heart disease (IHD) and obstructive and nonobstructive coronary artery (CA) disease.Material and methods. This cross-sectional observational study included 64 patients with IHD (diagnosis verified by coronary angiography or multislice computed tomography coronary angiography), of which 33 (51.6%) were men aged 64.9±8.1 years. 20 patients had nonobstructive CA disease (stenosis <50%), and 44 had hemodynamically significant stenoses. The control group consisted of 30 healthy volunteers. MMP-1, -9, -13, and -14, miRNA-34a, and VEGF were measured in all patients.Results. The concentration of MMP-1 was significantly higher in patients with ischemia and nonobstructive CA disease (INOCAD) (p=0.016), and the concentration of MMP-9 was the highest in the group with obstructive CA disease (p<0.001). The concentrations of MMP-13 and MMP-14 did not differ significantly between the groups. The highest VEGF concentrations were observed in the INOCAD group (p<0.001). The expression of miRNA-34a significantly differed between the IHD groups with different types of CA disease and controls (p <0.001). Patients with hemodynamically significant stenosis showed moderate relationships between the concentrations of MMP-14 and VEGF (ρ=0.418; p=0.024), as well as between VEGF and miRNA-34a (ρ=0.425; p=0.022). Patients with INOCAD had a significant negative correlation between the concentrations of MMP-13 and VEGF (ρ= –0.659; p=0.003). Correlation analysis showed in all IHD patients a moderate relationship of the concentrations of MMP-1 and MMP-14 with VEGF (ρ=0.449; p=0.002 and p=0.341; p=0.019, respectively). According to ROC analysis, a MMP-9 concentration above 4.83 ng/ml can be a predictor for the presence of hemodynamically significant CA obstruction in IHD patients; a VEGF concentration higher than 27.23 pg/ml suggests the absence of hemodynamically significant CA stenosis.Conclusion. IHD patients with INOCAD had the greatest increase in MMP-1, whereas patients with obstructive CA disease had the highest level of MMP-9. According to our data, concentrations of MMP-9 and VEGF can be used to predict the degree of CA obstruction. The expression of miRNA-34a was significantly higher in IHD patients with INOCAD and CA obstruction than in the control group, which suggested a miRNA-34a contribution to the development and progression of coronary atherosclerosis. In the future, it may be possible to use this miRNA as a diagnostic marker for IHD.
WOMEN RIGHTS ON REPRODUCTION IN QUR'ANIC PERSPECTIVES
Authors: Masnun tahir Erwati Aziz Nashruddin Baidan 
Published: May 2024

Abstract: There is an assumption that Islam is a barrier to equality between men and women. This happens partly due to errors in understanding and interpreting the Qur'an and Sunna because the subjectivity of the exegete is too dominant. Therefore, it is necessary to reinterpret the verses that are thought to inhibit equality objectively, rationally and argumentatively so that a correct and accurate interpretation is obtained.The study was conducted using the Mawdhu'i interpretation method, starting from the collection of verses relating to women's reproduction, then classified, interpreted and reviewed using the methods that are standard and standard.
The results of the study show that the Qur'an is very concerned about women's reproductive rights such as menstruation which causes women to be marginalized because they interpret the word ??? with "dirty" even though the Qur'an generally does not confirm that meaning but means "sick". This is very logical because women do indeed experience pain and other disorders during menstruation. The Qur'an gives special privileges to women who are menstruating and childbirth such as dispensation not to pray, delay fasting and so on. Thus the accusation that the Qur'an does not pay attention to this matter seems not supported by valid facts and fundamental and strong arguments
Abstrak: Muncul sebuah asumsi bahwa Islam merupakan sebuah penghalang bagi kesetaraan laki-laki dan perempuan. Hal ini terjadi sebagiannya akibat kesalahan dalam memahami dan menafsirkan Qur’an dan Sunnah disebabkan oleh subjektivtitas penafsir yang terlalu dominan. Oleh karena itu, perlu dilakukan penafsiran ulang terhadap ayat-ayat yang dianggap menghambat kesetaraan secara objektif, rasional, dan argumentatif sehingga penafsiran yang benar dan akurat dapat dicapai. Kajian ini dilakukan menggunakan metode tafsir maudhu’i yang dimulai dengan mengumpulkan ayat-ayat Qur’an yang berkaitan dengan reproduksi perempuan yang kemudian diklasifikasikan, ditafsirkan, serta diulas menggunakan metode standar. Hasil kajian ini menunjukkan bahwa Qur’an sangat memperhatikan hak reproduksi perempuan seperti perihal menstruasi yang mengakibatkan perempuan termarginalisasi karena kata ??? ditafsirkan sebagai “sesuatu yang kotor” meskipun secara umum Qur’an tidak membenarkan makna tersebut namun cenderung mengindikasikan makna “penyakit”. Hal ini sangat logis mengingat perempuan benar-benar mengalami rasa sakit dan kelainan selama masa menstruasi. Qur’an memberikan hak khusus bagi perempuan yang sedang mengalami menstruasi dan baru melahirkan berupa dispensasi untuk tidak melaksanakan ibadah shalat, menunda puasa, dan sebagainya. Oleh karena itu, tuduhan bahwa Qur’an tidak memberikan perhatian terhadap permasalahan ini tampaknya tidak didukung oleh fakta yang valid serta argumen yang kuat dan mendasar.

Published: May 2024

Improving the production technology of products with improved quality indicators and with less impact on the environment remains an urgent scientific and practical problem of paper industry enterprises. This refers to the technology for the production of paper-bases for wallpaper using environmentally safe chemical additives, in particular nanocellulose (NC), which was obtained by acid hydrolysis from reed cellulose. The production of cellulose was carried out in two stages - extraction from reed stalks with a solution of alkali and an organosolvent method of cooking in a solution of peracetic acid. The obtained organosolvent cellulose contained the remains of lignin and mineral substances, which allows it to be used for the preparation of NC. As a result of the hydrolysis of organosolvent cellulose, a time-stable NC suspension was extracted, the properties of which were investigated by scanning electron microscopy (morphological changes in the structure of reed cellulose-containing materials), atomic force microscopy (determination of topographic characteristics of NC), analysis of electronic absorption spectra (transparency of NC films). It was established that reed NC films had nanoparticles with a cross-sectional size of 5-25 nm, density up to 1.52 g/cm3, transparency up to 81.6 %, tensile strength up to 65 MPa.
For the production of castings of paper-bases for wallpaper samples, sulfated pine bleached cellulose and polyester synthetic fiber were used, to the fibrous mass of which were added the following chemical additives: alkyl ketene dimer, reed NC, binder, and optical brightener. It has been shown that the use of nanocellulose at a rate of 0.35 % to 1.0 % of the paper mass leads to a significant improvement in the physical and mechanical quality indicators of the paper base for wallpaper. It was established that the replacement of 50 % of the synthetic chemical auxiliary substance alkyl ketene dimer with nanocellulose or additional application of nanocellulose at a rate of 0.5 g/m2 on the surface of the casting with 0.7 % alkyl ketene dimer allows to obtain paper that meets the requirements of the standard. The obtained results indicate the prospects of using reed nanocellulose for the production of other mass types of paper and cardboard.

Abstract
The physical properties of shale oil reservoirs under overburden pressure are of great significance for reservoir prediction and evaluation during exploration and development. Based on core, thin section, and SEM observations, as well as test data such as XRD, TOC, and porosity and permeability under pressure conditions, this study systematically analyzes the variation of physical properties of different lithofacies shales in the Jiyang depression and the influence of rock fabric on the physical variation under pressure. The porosity and permeability of shale samples significantly decrease under pressure. According to the phased reduction in porosity and permeability, the pressurization process is divided into three pressure stages: low pressure (&lt;8 MPa), medium pressure (8–15 MPa), and high pressure (&gt;15 MPa). The reduction of porosity is fastest in the low-pressure stage and slowest in the medium-pressure stage. The reduction of permeability is fastest in the low-pressure stage and the slowest in the high-pressure stage. The rock fabric has a significant impact on porosity and permeability under pressure conditions. The permeability of laminated shale and bedded shale is higher than that of massive shale under pressure, and the permeability loss rate is lower than that of massive shales. Especially under lower pressure, the difference can be 10–20 times. In addition, the reduction rate of porosity and permeability under pressure is negatively correlated with felsic minerals content, which is positively correlated with carbonate minerals content and clay minerals content. The contribution of clay minerals to the porosity reduction rate is dominant, followed by carbonate minerals. The contribution of carbonate minerals to the permeability reduction rate is dominant, followed by clay minerals. The TOC content has no significant impact on the porosity and permeability of shales under pressure in the study due to the low maturity.
Insight into the Impact of Land Use/Land Cover Change on the runoff incorporating hydrological modelling in the water regime for the watershed

Published: May 2024

Abstract

Land and water are the two essential natural resources for human survival. Land Use/Land Cover is an important parameter governing the hydrology of a region. Increased human interventions have caused different modifications in the land cover, directly or indirectly affecting the hydrological cycle and processes in the long run. Raising urban and rural growth leads to an increase in the runoff by diminishing the perviousness of the region. Distributed hydrological modelling provides an efficient way to evaluate such changes by allowing quantification of streamflow patterns and distribution of hydrological components throughout the watershed. Remote sensing has the potential to be a more accurate tool for collecting spatial and temporal databases for studying hydrological processes. This study helps researchers to convey their ideas to the development of data collection and data extraction techniques, adoption of appropriate workflows for assembling multiple datasets, and analysis of the time-series impact of urbanisation on the watershed's runoff potential.

Abstract

Bilayer cathodes comprising two active materials are explored for their ability to improve lithium-ion battery charging performance. Electrodes are manufactured with various arrangements of lithium nickel manganese cobalt oxide Li[Ni0.6Co0.2Mn0.2]O2 (NMC622) and lithium iron phosphate LiFePO4 (LFP) active particles, including in two different discrete sub-layers. We present experimental data on the sensitivity of the electrode C rate performance to the electrode design. To understand the complex bilayer electrode performance, and to identify an optimal design for fast charging, we develop an extension to the Doyle-Fuller-Newman (DFN) model of electrode dynamics that accommodates different active materials in any number of sub-layers, termed the multilayer DFN (M-DFN) model. The M-DFN model is validated against experimental data and then used to explain the performance differences between the electrode arrangements. We show how the different open circuit potential functions of NMC and LFP can be exploited synergistically through electrode design. Manipulating the Li electrolyte concentration increases achievable capacity. Finally the M-DFN model is used to further optimise the best performing bilayer electrode arrangement by adjusting the ratio of the LFP and NMC sub-layer thickness.
