A Comparative Study Between Symmetrical and Asymmetrical Inverters

Inverters play a crucial role in modern power systems, converting direct current (DC) into alternating current(AC) for various applications. The choice between symmetrical and asymmetrical inverters can significantly impact system performance, efficiency, and cost. This paper presents a comprehensive comparative study of symmetrical and asymmetrical inverters, focusing on key parameters, design considerations, and their impact on system performance. Through extensive analysis and simulation, we aim to provide valuable insights for making informed decisions in selecting the appropriate inverter topology for their applications

Haplotype Analysis for DFNB4/PDS Locus in Hearing Impaired Families of Punjab (Pakistan)

Abstract: Deafness is one of the most common genetic disorders affecting 1 in 1000 newborns worldwide, while in Pakistan, its prevalence is 1.6/1000.The present study was conducted to map reported autosomal recessive deafness locus DFNB4/PDS in highly consanguineous families in Punjab. For this purpose families with deafness were identified . Blood samples of these families were studied for linkage analysis of common reported deafness locus DFNB4/PDS. Genomic DNA was isolated from the blood samples of these families. Linkage analysis was then performed by amplifying microsatellite markers through PCR, Genotyping was done by ABI PRISM ® 3730 Genetic Analyzer. The Deaf Family was found linked to microsatellite markers of DFNB4/PDS. Linkages analysis showed that all three affected were homozygous for three STR markers for DFNB4/PDS while individuals V: 3 was heterozygous i.e., is carrier for DFNB4. Therefore individuals V: 3 were phenotypically normal but genotypically he is carrier. As the ages of that affected individuals' ranges from three years to seven years they might develop goiter at a later age. Therefore at present this family is linked to an overlapping nonsyndromic/ syndromic locus DFNB4/PDS

Insight of novel biomarkers for papillary thyroid carcinoma through multiomics

IntroductionThe overdiagnosing of papillary thyroid carcinoma (PTC) in China necessitates the development of an evidence-based diagnosis and prognosis strategy in line with precision medicine. A landscape of PTC in Chinese cohorts is needed to provide comprehensiveness.Methods6 paired PTC samples were employed for whole-exome sequencing, RNA sequencing, and data-dependent acquisition mass spectrum analysis. Weighted gene co-expression network analysis and protein-protein interactions networks were used to screen for hub genes. Moreover, we verified the hub genes' diagnostic and prognostic potential using online databases. Logistic regression was employed to construct a diagnostic model, and we evaluated its efficacy and specificity based on TCGA-THCA and GEO datasets.ResultsThe basic multiomics landscape of PTC among local patients were drawn. The similarities and differences were compared between the Chinese cohort and TCGA-THCA cohorts, including the identification of PNPLA5 as a driver gene in addition to BRAF mutation. Besides, we found 572 differentially expressed genes and 79 differentially expressed proteins. Through integrative analysis, we identified 17 hub genes for prognosis and diagnosis of PTC. Four of these genes, ABR, AHNAK2, GPX1, and TPO, were used to construct a diagnostic model with high accuracy, explicitly targeting PTC (AUC=0.969/0.959 in training/test sets).DiscussionMultiomics analysis of the Chinese cohort demonstrated significant distinctions compared to TCGA-THCA cohorts, highlighting the unique genetic characteristics of Chinese individuals with PTC. The novel biomarkers, holding potential for diagnosis and prognosis of PTC, were identified. Furthermore, these biomarkers provide a valuable tool for precise medicine, especially for immunotherapeutic or nanomedicine based cancer therapy

Tuberculosis is associated with expansion of a motile, permissive and immunomodulatory CD16(+) monocyte population via the IL-10/STAT3 axis

The human CD14+ monocyte compartment is composed by two subsets based on CD16 expression. We previously reported that this compartment is perturbed in tuberculosis (TB) patients, as reflected by the expansion of CD16+ monocytes along with disease severity. Whether this unbalance is beneficial or detrimental to host defense remains to be elucidated. Here in the context of active TB, we demonstrate that human monocytes are predisposed to differentiate towards an anti-inflammatory (M2-like) macrophage activation program characterized by theCD16+CD163+MerTK+pSTAT3+ phenotype and functional properties such as enhanced protease-dependent motility, pathogen permissivity and immunomodulation. This process is dependent on STAT3 activation, and loss-of-function experiments point towards a detrimental role in host defense against TB. Importantly, we provide a critical correlation between the abundance of the CD16+CD163+MerTK+pSTAT3+ cells and the progression of the disease either at the local level in a non-human primate tuberculous granuloma context, or at the systemic level through the detection of the soluble form of CD163 in human sera. Collectively, this study argues for the pathogenic role of the CD16+CD163+MerTK+pSTAT3+ monocyte-to-macrophage differentiation program and its potential as a target for TB therapy,and promotes the detection of circulating CD163 as a potential biomarker for disease progression and monitoringof treatment efficacy.Fil: Lastrucci, Claire.

Inclusive Education of Student with Disabilities in Arab Countries: A Review of the Research Literature from 2000 to 2019

This study aimed to review and analyze research related to inclusive education for students with disabilities in Arab countries and published in the past twenty years, from 2000 to 2019; in addition, it aimed to expose the details of that research (the distribution of study according to the Arab countries in which it was conducted, the gender of the target samples, the categories of disability, the educational stages, and the educational institutions in which they were shown), This study focused on research carried out in Arab countries to discover the most prominent results of these researches. The research consisted of 278 studies carried out in Arab countries, and of these, the study identified which ones had the most noteworthy results. About three-quarters of these studies were focused on both males and females. Arabian researchers used college students with disabilities and elementary school teachers as samples. The study found that students with mental disabilities score higher than students with other disabilities in the special needs category. The study showed that nearly all of the research initiatives conducted by Arabs were carried out at the primary levels. Governmental institutions were where most of these initiatives were carried out. The topics that were studied most were issues with inclusive education. As a result, the study has recommended several recommendations, the most important of which is conducting more meta-studies in Internet usage in Arab countries. Keywords: Inclusive Education, Students with Disabilities, Arab Countries, A Review of Research. DOI: 10.7176/JEP/12-33-09 Publication date: November 30th 2021

Optical absorption of Zn(V,Al)O thin films studied by spectroscopic ellipsometry from 1 to 6 eV

Aerogel nanoparticles prepared with various Al concentrations were used as a target for the deposition of (V,Al) co-doped ZnO films by rf-magnetron sputtering on glass substrates. The influence of Al content on the structural and the optical properties of the Zn(V,Al)O films was investigated by X-ray diffraction and spectroscopic ellipsometry (SE). It is found that all films exhibit one high intensity (0 0 2) peak, indicating that they have c-axis preferred orientation due to self-texturing mechanism. SE measurements, used to determine the complex pseudo dielectric functions, were carried out at room temperature in the 1–6 eV photon energy region. The excitonic edge of the fundamental band gap (E0) transition in the imaginary part of the dielectric function of the Zn(V,Al)O films is observed around 3.5 eV and shows a dependence on the Al content. The E0 absorption edge of the Zn0.9−x V0.1AlxO alloys shows a blueshift from that of pure ZnO, reaching 389 meV for x = 0.02. This blueshift is interpreted by the Burstein-Moss effect. By analyzing the dielectric function, reduced effective mass m* of the Zn0.9−x V0.1AlxO alloy is extracted and shows good agreement with literature values
