Pure Ni nanopowders were successfully prepared by the method of anodic arc disch arged plasma with homemade experimental apparatus. The particle size, mircostruc ture and morphology of the particles by this process were characterized via X-ra y powder diffraction (XRD), transmission electron microscopy (TEm) and the corre sponding selected area electron diffraction (SAED); The specific surface area an d pore parameters were investigated by multi-point full analysis of nitrogen ads orption-desorption isotherms at 77K by Brunauer- Emmett-Teller (BET) surface are a analyzer; The chemical composition were determined by X-ray energy dispersive spectrometry (XEDS) equipped in SEm and element analyze instrument. The experime nt results indicate that the samples by this method with high purity,the crystal structure of the particles is as same as the bulk material, is fcc structure, w ith average particle sizes about 47nm, ranging from 20 to 70nm, and distributed uniformly in spherical chain shapes, the specific surface areavis 14.23m2/g, po re volume of pore is 0.09cm3/g and average pore diameter is 23nm.

Analysis of Association between Interleukin-6 (IL6), Interleukin-13 (IL13) and Tumor Necrosis Factor-Alpha (TNF-alpha) Gene Polymorphisms and Genetic Susceptibility of Rheumatoid Arthritis in Kuwaiti Arab

引用

Open Journal of Rheumatology and Autoimmune Diseases 2022年第4期12卷 99-113页

作者： Adel m. Al-Awadhi mohammad z. haider Aminah m. Al-Awadi Anita K. Kalarikkal Jalaja Sukumaran Eman A. h. hasan Youssef Bartella Department of medicine College of Medicine Kuwait University Jabriya Kuwait Rheumatic Disease Unit Amiri Hospital Dasman Kuwait Department of Pediatrics College of Medicine Kuwait University Jabriya Kuwait

Background: Rheumatoid arthritis (ra) is a common autoimmune disease in which a combination of risk alleles from different susceptibility genes predisposes the patients to develop clinical symptoms following exposure to environmental factors. ra is a chronic and progressive disease characterized by synovial inflammation that results in destruction in the affected joints and severe problems in individual’s mobility. Several immune-related risk factors have been associated with ra, these include single nucleotide polymorphisms (SNPs) in cytokine genes. The impact of these cytokine gene polymorphisms is due to their association either with elevated serum levels and/or variations in their serum levels are associated with disease-onset and progression. The objective of this study was to investigate the role of Interleukin-6 (IL6), Interleukin-13 (IL13) and Tumor necrosis factor-alpha (TNF-alpha) gene polymorphisms in genetic susceptibility of ra in Kuwaiti patients. methods: We have determined the genotypes of IL6 gene (-174G/C;rs1800795), IL13 gene (R130Q;rs20541) and TNF-alpha gene (-308A/G' rs1800629) polymorphisms in 192 Kuwaiti patients with ra and compared it to that in 104 healthy controls. The diagnosis of ra was based on the American College of Rheumatology (ACR) classification criteria. The genotypes for IL6, IL13 and TNF-alpha gene polymorphisms were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methods and confirmed by DNA sequencing. Results: The frequency of IL6 gene (-174G/C;rs1800795) and TNF-alpha gene (-308A/G' rs1800629) polymorphisms manifested a statistically significant difference between Kuwaiti ra patients and controls (P = 0.02 and 0.002 respectively). In contrast, the frequency of IL13 gene (R130Q;rs20541) polymorphism did not show a significant difference between Kuwaiti ra patients and controls. Conclusions: Our data showed an association of two cytokine gene polymorphisms (i.e. IL6 gene -174G/C;rs

Objective: Analyze the maternal mortality in the two departments of ChU Point “G” in Bamako, because of high maternal mortality rate in our country. material and methods: This was an analytical cross-sectional study on maternal deaths from February 19, 2005 to November 19, 2019 for patients admitted in both departments and who died during the pregnancy-puerperal period at ChU Point “G”. All the patients who died outside this pregnancy-puerperal period were not retained. The data were entered and analyzed using SPSS 12.0 software. The statistical test used was that of Chi2, the statistical significance threshold was fixed at 5%. Results: During our study, we recorded 389 maternal deaths out of 16,033 admissions in 15 years and 18,060 live births during the same period making a maternal mortality ratio of 2153.931 and a frequency of 2.426. At the end of our study, we noted that the frequency of maternal deaths was higher in 2014: 12.9% (50/389). The maternal death predominantly affected women aged of 20 - 24 with a frequency of 22.4% (87/389). The multiparity (166/389 making 42.7%), illiteracy (341/389 making 87.7%), the poor evacuation conditions (non-medicalized transport): 263/389 making 67.6%;the evacuation without any evacuation sheet: 259/389 making 66.6%), poor CPN (Prenatal consultation) quality (undone CPN: 191/389 making 49.1%) and the poor monitoring of delivery works (no use of partograph in 343/389 making 88.2%) were the factors favoring maternal deaths. The main causes of maternal deaths were direct in 231/389 making 59.4% with hemorrhage in first line: 21.1% (82/389), infection (61/389 cases making 15.68%), dystocia: 50 cases making 12.85% and high blood pressure and complications (38/389 making 9.76%);indirect in 158/389 cases making 40.6% (Figures 1-3). The majority of women 65.8% (256/389) of our patients died in the gynecology and obstetrics department;in the Resuscitation department 73/389 making 18.8%;in the operating room 43/389 making 11.1% and
