CLINICAL AND NEUROPHYSIOLOGICAL CHARACTERISTICS OF NEUROPHTHALMOLOGICAL DISORDERS IN CHILDREN WITH SPEECH DELAY
Authors: Sh. Sh. Shamansurov  , D.K. Makhkamova  , I. K. Abdukadirova
Published: May 2024

The problem of late development of speech activity in young children without severe mental pathology is becoming more and more relevant every year (Baranov A.A., 2012; Larkina E.V. et al., 2013; Makushkin E.V., 2013; Asmolova G. A. et al., 2014; Borovtsova L.A. et al., 2015). The lag in a child’s speech development from the age norm is observed mainly in the early stages of the formation of mental activity (Shemyakina O.V., 2012). Disorders that arise in childhood do not disappear without a trace, but can worsen over time (Kuprianova I.E. et al., 2012; Clegg J. et al., 2005; Miniscalco C., et al., 2006; Bayer J.K. et al. ., 2008; Durkin, K., 2010).
The role of the visual analyzer in the mental development of a child is great and unique. Violation of its function causes the child significant difficulties in understanding the surrounding reality, narrows social contacts, limits spatial orientation and the ability to engage in many types of activities [4].
An analysis of special psychological and pedagogical literature has shown that the peculiarities of the development of visual perception, insufficient development of motor and visual-motor coordination delay the process of mastering objective actions by a child with visual impairments and negatively affect the process of forming their ideas about objects in the surrounding world. The operational, functional and motivational aspects of object concepts in these children are not sufficiently developed, and without special work the formation of this mental process is extended over time.
The nature of the dysfunction of the central nervous system in children with delayed speech development affects the characteristics of the generation of visual evoked potentials (VEPs). The configurations of early and late VEP components differ significantly in children with speech delay and healthy children. With delayed speech development of various origins, the amplitude of the negative VEP component is reduced in the frontal, temporal and occipital regions of both hemispheres of the brain compared to the control. It has been established that a decrease in the amplitude of positive VEP components is associated with impaired attention function.

SPEECH DELAY: A VIEW OF THE PROBLEM
Authors: I. K. Abdukadirova  , D.K. Makhkamova
Published: May 2024

The problem of late development of speech activity in young children without pronounced mental pathology is becoming more and more relevant every year (Borovtsova L.A. et al., 2015 Vatoropina S.V. et al. 2015). As a rule, all children after three years of age, whose speech is characterized by extremely limited use of linguistic means, are diagnosed with general speech underdevelopment (according to P.E. Levina).
At the same time, the mechanisms of this disorder may be different. Insufficient knowledge of the clinical forms of speech underdevelopment, as well as the similarity of their manifestations, makes it difficult to differentiate the tempo delay of speech development and its impaired variant. Speech therapy intervention in these cases is often built without taking into account the clinical uniqueness of children and the mechanisms of delay in speech development, which, accordingly, reduces the effectiveness of the work carried out. At the same time, any phenomenon subjected to scientific analysis must be determined by its most characteristic features, distinguishing it from other similar phenomena. (Guseva A.Yu. 2022)

Published: May 2024

Fase perkecambahan termasuk salah satu fase yang peka terhadap cekaman abiotik termasuk cekaman salinitas. Priming benih dapat meningkatkan viabilitas benih sekaligus mereduksi dampak negatif cekaman salinitas. Tujuan dari riset ini adalah untuk mempelajari potensi priming benih dari ekstrak biji akpukat dalam memitigasi cekaman salinitas pada fase perkecambahan kedelai hitam. Percobaan dilakukan di Rumah kaca Fakultas Pertanian Universitas Siliwangi dari bulan April sampai bulan Juli 2021, dengan menggunakan rancangan acak kelompok yang berpola faktorial. Faktor 1 = priming ekstrak biji alpukat (0%, 1%, 3%, dan 5%), dan faktor 2 = cekaman salinitas (DHL= 0,87 dS m-1 , 10,92 dS m-1), dan 17,77 dS m-1). Analisis statistik menggunakan Anova dan dilanjutkan dengan uji Duncan. Hasil riset ini menunjukkan bahwa ekstrak biji alpukat menunjukkan aktivitas antioksidan yang sangat kuat, dengan IC50 = 22,83 µg mL-1. Priming benih dengan ekstrak biji alpukat dan cekaman salinitas tidak menimbulkan pengaruh interaksi secara signifikan terhadap perkecambahan benih kedelai hitam. Secara mandiri cekaman salinitas menimbulkan dampak negatif bagi perkecambahan benih kedelai hitam, sebaliknya priming benih menggunakan ekstrak biji alpukat berpotensi dapat memitigasi dampak cekaman salinitas serta meningkatkan viabilitas benih kedelai hitam.     The germination phase is one of the phases that is sensitive to abiotic stress, including salinity stress. Seed priming can increase seed viability while reducing the negative impact of salinity stress. The aim of this research is to study the potential of seed priming from avocado seed extract in mitigating salinity stress in the germination phase of black soybeans. The experiment was carried out in the greenhouse of the Faculty of Agriculture, Siliwangi University from April to July 2021, using a randomized block design with a factorial pattern. Factor 1 = avocado seed extract priming (0%, 1%, 3%, and 5%), and factor 2 = salinity stress (EC = 0.87 dS m-1, 10.92 dS m-1), and 17 .77 dS m-1). Statistical analysis used Anova and continued with the Duncan test. The results of this research show that avocado seed extract shows very strong antioxidant activity, with IC50 = 22.83 µg mL-1. Priming seeds with avocado seed extract and salinity stress did not have a significant interaction effect on black soybean seed germination. Independently, salinity stress has a negative impact on black soybean seed germination, on the other hand, seed priming using avocado seed extract has the potential to mitigate the impact of salinity stress and increase the viability of black soybean seeds.

Published: May 2024

Indoor air pollution (IAP) is an important cause of concern for human health, leading to millions of deaths worldwide each year. Since people spend most of their time indoor the quality of the air inhaled during routine activities is of primary importance. IAP include particulate matter (PM), volatile organic compounds (VOCs), chemical gases, heavy metals, and biological contaminants. Unfortunately, their sources are various and widespread all over the household and other indoor environments, causing relevant health consequences. This narrative review aims to provide a comprehensive framework of the indoor pollutants effects on subjects affected by asthma, allergic rhinitis, and atopic dermatitis. As pivotal barriers against pollutants, in fact, respiratory and cutaneous districts can be particularly affected by IAP, especially in case of atopic diseases. On the other hand, the application of targeted adjustments, such as the avoidance of cigarette smoking, the use of hoods while cooking, the choice of adequate ventilation systems, and the use of low-emitting building materials and furniture may result in the improvement of indoor quality.

Aim: This study aimed to develop and evaluate an in-house enzyme-linked immunosorbent assay (ELISA) based on autochthonous antigens to detect immunoglobulin G (IgG) antibodies against Helicobacter pylori (H. pylori) in adult sera. Methods: Whole-cell antigens from three genetically characterized clinical isolates of H. pylori were mixed and used as coating antigens. This assay was validated with a panel of human sera samples of H. pylori seropositive and seronegative patients. Likewise, sera samples from patients with uninvestigated dyspepsia, who were also evaluated by invasive and noninvasive tests (i.e., histopathology, rapid urease test, and stool antigen test), blood donors and patients with confirmed viral and parasitic diseases were also collected. The IgG response against H. pylori was detected by the in-house assay using the commercial ELISA IBL (Germany), as a reference test. Statistical analysis was performed with GraphPad Prism version 5.01. Results: The in-house ELISA showed high repeatability and reproducibility. Sensitivity was 91.1%; 95% confidence interval (CI): 87.2–94.0, specificity was 94.8% (95% CI: 85.0–94.8), and accuracy was 91.6% (95% CI: 88.5–94.6). The in-house ELISA showed an excellent area under the curve (0.96; 95% CI: 0.93–0.98) and a better IgG detection by the inverse cumulative distribution. The frequency of seropositivity in patients with dyspepsia (76.0%) was significantly higher (P < 0.05) than in healthy individuals (57.7%) and patients with other infectious diseases resembling H. pylori infection symptoms (54.4%). The H. pylori seroprevalence was estimated to be 62.7%. A good correlation was found between IgG seropositivity and H. pylori infection diagnosed by histopathology, rapid urease test, and stool antigen test in Cuban adults with dyspepsia. Conclusions: The in-house ELISA demonstrated good diagnostic accuracy and potential usefulness for estimating H. pylori exposure in the adult population, henceforward, this method could be used as an alternative for H. pylori diagnosis in the Cuban setting.

أن البذور الأولى للتصوف الإسلامي موجودة في القرآن  الكريم. ومن هنا يكون التصوف، من حيث نشأته، إسلاميا. فقد مرّ التصوف في الإسلام بمراحل متعددة, وتواردت عليه ظروف مختلفة واتخذ تبعاً لكلّ مرحلة ووفقاً لمّا مرّ به من ظروف مفاهيم متعددة و لذالك كثرت تعريفاته وكل تعريف منها قد يشير إلى بعض جوانبه دون البعض الآخر، ولكن يظل هناك أساس واحد للتصوف لا خلاف عليه، وهو أنه أخلاقيات مستمدة من الإسلام. فالزهد والتصوف الإسلامي أصولهما القرآن والسنة ،وحياة الرسول ،وأخلاقه وأقواله كانت هي أيضاً مصدرا من مصادر التصوف، فهي بالنسبة للصوفي تعد منبعا يستقى منه، فقد وجدوا الصوفية في حياة الرسول، قبل البعثة وبعدها ،مصدراً غنياً استمدوا منها صنوف العلم وضروب العمل. وإذا قارنا بين الزهد والتصوف من النواحي المنهجية والفكرية والغائية، فإننا نجد من الناحية المنهجية أن الزاهد دائماً حدوده الشرع، ووسيلته التكاليف الدينية، أما المتصوف فهو ذو شخصية شبه مستقلة، فإن أوّل، ولم يخرج على الأصول، كان متصوفاً إيجابياً، وإن أوّل وخرج، ولم يهتم بالوسيلة في التكاليف الدينية، كان متصوفاً سلبياً، يرى أنه من الخواص أصحاب العرفان.

Synthesis and physical properties of tunable aryl alkyl ionic liquids based on 1-aryl-4,5-dimethylimidazolium cations
Authors: Fritsch Stefan , Strassner Thomas
Published: May 2024

We present a new class of tunable aryl alkyl ionic liquids (TAAILs) based on 1-aryl-4,5-dimethylimidazolium cations with electron-withdrawing and -donating substituents in different positions of the phenyl ring and the bis(trifluoromethylsulfonyl)imide (NTf2) anion. We investigated the effect of additional methyl groups in the backbone of the imidazolium core on the physical properties regarding viscosity, conductivity and electrochemical window. With an electrochemical window of up to 6.3 V, which is unprecedented for TAAILs with an NTf2 anion, this new class of TAAILs demonstrates the opportunities that arise from modifications in the backbone of the imidazolium cation.

This study investigates the effect of different sowing media and soil amendments on seed germination and early seedling growth of Pterocarpus osun. The study was carried out at the nursery site of the Department of Forest Resources and Wildlife Management, Ekiti State University, Ado-Ekiti. Sixty seeds were sown in plastic bowls filled with the different sowing media (sawdust, river sand, and topsoil). Watering was done twice daily, while seed germination was monitored for four weeks. The number of seeds germinated per day was recorded for each treatment till no further germination was observed.  For the growth experiment, seedlings with relatively uniform height were selected and transplanted into polythene pots filled with topsoil amended with different organic manure (poultry dropping, cow dung, poultry dropping + cow dung). The treatments were replicated ten (10) times. Growth parameters viz; (heights, stem diameter, and number of leaves) were measured over 12 weeks. The study revealed that seeds sown in sawdust had the lowest mean germination time (MGT) of 19.93 days. Time spread of germination (TSG) shows that seeds sown in river sand had the longest germination circle of 12 days. While seeds sown in sawdust had the highest germination percentage (GP) of 96.65 %. The result revealed that seedlings grown on soil amended with cow dung performed best for all the parameters measured throughout the growth period. It is recommended that sawdust should be adopted for germination of Pterocarpus osun and cow dung should be used as organic manure for raising the seedlings in the nursery.

Benzene is a colorless liquid that easily evaporates in the air and can lead to negative impacts on the workers’ health. Also, it can cause cancer. This study aimed to evaluate the effect of benzene on the ferritin level and blood of workers in petrol station.
This study has a cross sectional design. It includes 32 participants out of which 16 are exposed workers and 16 non exposed ones. The data was collected by using a questionnaire about socio-demographic characteristics and symptoms of benzene exposure. Also, Blood samples were taken to test ferritin and complete blood counts and analyzed by using Statistical Package for Social Sciences. The results of the study revealed that exposure to benzene in some workers leads to decreasing serum ferritin, MCV, MXD and MCH, and increased WBC, RBC, and HCT. There was a statistical difference in the WBC, RBC, MCV, MCH, LYM, and MXD between the exposed and non-exposed groups. There was a positive relationship between years of experience and effects of benzene on WBC, and a clear correlation between the exposed workers’ age, HGB and ferritin levels. Benzene has negative impacts on the health of workers, which dictates the necessity of worker wearing personal protective equipment in the workplace.
Gender Inequality in Youth Employment in Urban Ethiopia: Trends and Policy Implications

Published: May 2024

The issue of employment for youth and women is a matter of concern as these groups tend to be disadvantaged in the labour market. This paper attempts to investigate the changes in distribution of youth labour participation and wage gaps in urban market based on gender. The study employed a mixed quantitative and qualitative research approach. Gender wage gap and Employment Outcome Estimation models applied. The Urban Employment Unemployment Survey (UEUS) cross-sectional data collected annually, over the 2003 to 2018 period, is used as the main source to provide new evidence on the distribution of gender inequality in youth employment in urban Ethiopia. Further, qualitative data is collected from 10 key informants from government institutions. The findings indicate that wage employment is dominated by male workers over the last two decades while vulnerable employments and unpaid family works are dominating by the young female. The gender wage gap has been widening over the last two decades suggesting the young female workers have benefit little from the labor market opportunities. The wage gap was more due to unexplained factors than the explained ones (differences related with choice of industry and occupation, education and potential experiences). Based on the findings the following recommendations are forwarded: Information dissemination system for young women regarding the labor market should be improved, work on societal norms and values that encourage gender discrimination, government should apply its coercive power to enforce policies to minimize employment gender discrimination, the education system should be skilled-based with provision of entrepreneurial skills trainings to student.
