BackgroundMultiple intersections, including socioeconomic inequalities, influence health equity for disabled people and sub-populations. However, this association has not been sufficiently analyzed among Chinese-impaired persons. This study aimed to investigate the health services utilization and inequalities in middle and older adult persons with disabilities and subgroups.MethodsThe China Health and Retirement Longitudinal Study (CHARLS) database in 2011, 2013, 2015, and 2018 were used. Health services utilization was measured by outpatient, inpatient, and self-treatment service utilization. Types of disabilities were classified into six categories. The pooled cross-section regression, concentration index, horizontal inequity index, and concentration index decomposition were used to evaluate inequalities and explore their main contributing factor.ResultsThe utilization and non-utilization of healthcare services showed variations across years (p &lt; 0.05). The CIs and HIs for inpatient health service utilization were positive for all years and disability types. The total CIs of inpatient utilization were the highest (0.248). The highest disparities in utilization of inpatient services were for physical disabilities (0.4515 for CI in 2011), and the highest in self-treatment services were for intellectual disability (0.1538 for CI in 2011). The expenditure factor was the main contributor to inequalities. Chronic disease, educational level, and health insurance factors also contribute to the utilization inequalities.ConclusionPolicies should promote medical insurance and assistance for disabled people with serious impairment and poor. It is crucial to improve the provision of basic medical services, including meeting the demand for varied disabilities and the accessibility of facilities and equipment to enhance the access and well-being of people with disabilities.

IntroductionPrior research identified four neurochemical cerebrospinal fluid (CSF) biomarkers, Aβ1–42, Aβ1–40, tTau, and pTau(181), as core diagnostic markers for Alzheimer's disease (AD). Determination of AD biomarkers using immunoassays can support differential diagnosis of AD vs. several neuropsychiatric disorders, which is important because the respective treatment regimens differ. Results of biomarker determination can be classified according to the Amyloid/Tau/Neurodegeneration (ATN) system into profiles. Less is known about the clinical performance of chemiluminescence immunoassays (ChLIA) measuring specific biomarkers in CSF samples from patients suffering from neuropsychiatric impairments with various underlying causes.MethodsChemiluminescence immunoassays (ChLIAs, EUROIMMUN) were used to determine Beta-Amyloid (1–40), Beta-Amyloid (1–42), Total-Tau, and pTau(181) concentrations in precharacterized cerebrospinal fluid (CSF) samples from 219 AD patients, 74 patients with mild cognitive impairment (MCI), and 220 disease control (DC) patients.Results83.0% of AD patients had ATN profiles consistent with AD, whereas 85.5% of DC patients and 77.0% of MCI patients had profiles inconsistent with AD. AD patients showed significantly lower amyloid ratio Aβ1–42/Aβ1–40 (mean: 0.07) and significantly higher concentrations of tTau (mean: 901.6 pg/ml) and pTau(181) (mean: 129 pg/ml) compared to DC and MCI patients (all p values &lt; 0.0071).DiscussionThe ChLIAs effectively determined specific biomarkers and can support differential diagnostics of AD. Their quality was demonstrated in samples from 513 patients with cognitive impairments, representing a realistic mix of underlying causes for seeking treatment at a memory clinic.

ObjectivesChildhood overweight/obesity is a serious public health problem in the world today specially low-and-middle income countries like Ethiopia. This study aimed to assess the prevalence of overweight/obesity and associated factors among preschool children.MethodsA community-based cross-sectional study was conducted among preschool children aged 3–5 years in Arba Minch city from April to June 2022. A multistage sampling method was used to select 577 study participants. Data were collected using a structured and pretested questionnaire. A binary logistic regression model was used for analysis. An adjusted odds ratio (AOR) with a 95% confidence interval (CI) was used to assess the strength of the association.ResultsThe combined prevalence of overweight/obesity was 23.9% (95% CI: 20.5, 27.6). Age of 36–47 months, family size &lt; five, watching TV/video for ≥2 h, and consuming sweet foods, were factors associated with being overweight/obese among preschool children.ConclusionOverweight/obesity was predicted by consuming sweet foods, long time TV/video watching, and large family size in the study area. Special attention should be given to child feeding practices and reducing sedentary lifestyles.

Была установлена зависимость степени деагломерации углеродных нанотрубок (УНТ) от количества обработок методом быстрого расширения сверхкритических суспензий (RESS) в различных условиях. Впервые показано, что двукратная обработка методом RESS позволяет увеличивать степень деагломерации УНТ более эффективно по сравнению с однократной. Трехкратная обработка в случае применения азота как растворителя приводит к незначительному увеличению степени диспергирования по сравнению с двукратной. В случае применения СО2 как растворителя трехкратная обработка приводит к уменьшению степени диспергирования по сравнению с двукратной. При использовании азота в качестве среды диспергирования изменение давления не приводит к изменению степени диспергирования УНТ. При использовании СО2 — снижение плотности флюида обеспечивает большую эффективность обработки УНТ. Таким образом, для эффективного диспергирования УНТ методом многократной RESS-обработки имеет смысл использовать либо двукратную обработку азотом, либо низкоплотным СО2.
The dependence of the degree of CNT deagglomeration on the multiplicity of their treatment by the method of rapid expansion of supercritical suspensions (RESS) under various conditions has been studied. It was shown that double treatment by the RESS method makes it possible to increase the degree of CNT deagglomeration more effectively than a single one. Three-fold treatment in the case of nitrogen leads to a slight increase in the degree of dispersion compared to two-fold. In the case of CO2, three-fold treatment can lead to both an increase and a decrease in the degree of dispersion compared to twofold. When nitrogen is used as a dispersion medium, changes in temperature and pressure do not lead to a change in the degree of dispersion of CNTs. When using CO2, a decrease in fluid density ensures greater efficiency of CNT processing.

Переработку гидролизного лигнина в среде сверхкритического н-гексана осуществляли в две стадии: 1) термическая обработка лигнина в автоклаве при 250°С и 15 MПa в среде аргона; 2) гидрирование раствора полученных на первой стадии продуктов при 250°С и 9,0 MПa в присутствии катализатора Ru/C. Полученные на первой и второй стадиях продукты анализировали методами высокоэффективной жидкостной хроматографии, гель-проникающей хроматографии и газовой хроматографии, хромато-масс-спектрометрии и элементного анализа. На первой стадии степень деполимеризации составила 17 %; перешедшие в раствор в результате деполимеризации моно- и олигомерные фрагменты лигнина имеют молекулярномассовое распределение (ММР) в пределах от 65 Да до 270 кДа. Определен состав мономеров в продуктах деполимеризации первой стадии: моно-, ди, три- и тетраалкилпроизводные бензола (2,8 мас. %), гваякол и его 4-алкилпроизводные (0,6 мас. %), в том числе конифериловый спирт (0,06 мас. %). На второй стадии происходят следующие процессы: 1) деполимеризация олигомеров до мономеров; 2) гидрирование мономерных фенолов в оксо- и алкилпроизводные циклогексана; 3) образование газовых продуктов (преимущественно метана, 95 об. %) вследствие каталитического гидрокрекинга растворителя.
Depolymerization of hydrolysis lignin in supercritical n-hexane medium was carried out in two stages: 1) lignin treatment in an autoclave at 250°C and 15 MPa; 2) hydrogenation of the solution obtained in the first stage at 250°C and 9 MPa on a Ru/C catalyst. The products of the first and second stages were analyzed by HPLC, GPC, gas chromatography, chromatography-mass spectrometry, and elemental analysis. At the first stage, the degree of depolymerization was 17 %, the mono- and oligomeric fragments of lignin that passed into solution as a result of depolymerization have an MMD from 65 Da to 270 kDa. Monomer composition of the solution: mono-, di-, tri- and tetraalkyl derivatives of benzene (2.8 wt. %), guaiacol and its alkyl derivatives (0.6 wt. %), including coniferyl alcohol (0.06 wt. %). At the second stage of transformation the following processes occur: 1) depolymerization of oligomers to monomers; 2) hydrogenation of monomeric phenols to derivatives of cyclohexane and its oxo derivatives; 3) formation of gas products, mainly methane (95 vol. %), as a result of hydrocracking of the solvent.

Published: October 2024

Abstract
Recent progresses in ionic current analyses related to micro- and nano-object sensing, electrochemical sensors, and liquid pollution monitoring have attracted significant attention. Micro- and nanoscale sensors with high spatial resolution and high signal-to-noise ratios are also effective for obtaining detailed understanding of ion transport phenomena. We have developed a glass microelectrode technique for measuring the electrical potential distribution by scanning through liquids. It enables us to directly evaluate electrical properties with a spatial resolution equal to the glass tip diameter, which is less than 1 μm. Herein, we optimize the channel and cell structures for the analysis of temperature-dependent properties, which allows us to measure the temperature dependence of conductivity and viscosity in the range of 303–333 K based on the Stokes–Einstein relation. The proposed method, which directly measures the spatial distribution of electrical potential, is suitable for analyzing conductivity, viscosity, and concentration without preprocessing calibration.

Robots are one of the technologies that is currently advancing quickly. Generally speaking, a robot's movement is similar to that of an automobile; it can only move forward, backward, left, and right. Because the movement is controlled by these movements, it is thought that the robot's movement is extremely restricted to the left and right directions. solely with the front wheels. As a result, a robot was developed in this study that can control sliding motions to the left and right utilizing omniwheels on its front and back wheels. Badminton is a sport involving rackets that is played by two people or two opposing pairs. Robotic badminton players are employed as a substitute for human trainers in the training process, particularly for service and drive motions. With the use of a wireless joystick, the robot's ATMega 8535 microprocessor controls both the robot's direction of motion and the movement of its racket. Using a double acting pneumatic cylinder that requires 7 bar of air pressure, the robot service arm uses the compressor's air pressure. The average time it takes for the racket to strike the ball at 7 bar of wind pressure is 00:5.2 seconds. The time it takes for the ball to fall onto the racket in the absence of wind pressure is 00:28 seconds on average. A difference value of 00:22.7 seconds is acquired, and this value will be utilized as the programming reference delay. The robot encounters a slope with an average angle change of 7º when moving forward, an average angle change of 10º when moving backward, an average angle change of 5.2º when moving right, and an average angle change of 3º when moving left. The uneven field surface causes the robot to move at a slope, which modifies the speed of the motor on the wheels
