Advances in Remote Sensing 2016年第4期5卷 355-371页

作者： nadir A. Hameid Mohamed A. Bannari Hassan Mohamed Fadul Sumia Zakieldeen Department of Geoinformatic College of Graduate Studies Arabian Gulf University Manama Kingdom of Bahrain UNESCO Chair in Water Resources Omdurman Islamic University Khartoum Sudan Institute of Environmental Studies University of Khartoum Khartoum Sudan

Since the last assessment of ecological zones of Sudan conducted in 1958 by Harrison and Jackson, the vegetation types, cover, and its distribution have undergone remarkable changes;this change occurs in most of the predominant ecological zones, particularly those which are currently affected by environmental degradation and desertification due to climate change impact on vegetation cover and rainfall amounts and its distribution. In addition, during the last five decades, Sudan has suffered from environmental devastating changes that have undermined food security, which is strongly linked to human displacement and related conflicts. In this study, SPOTVEG NDVI data acquired between 2000 and 2010 were used to produce a vegetation cover map, which was integrated with rainfall map to produce updated ecological zones map for the study area in 2010. This map was compared to that produced in 1958 to analyze the change during the last five decades. The obtained results showed drastic change concerning different ecological zones. The desert class increased by 11%. The Semi-Desert class decreased by approximately 13.2%. The woodland savannah class increased by 6.8%. While, the Mountain vegetation areas decreased approximately by 3%. Finally, the wetland areas completely disappeared in 2010. These results show that during the period 1958-2010, climate change impact increased desertification process, destroyed ecological zones, especially wetland, as well the ecosystems diversity in Central Sudan.

目的:报道应用新的B超检查参数(最大交叉截面积)测量评估随访患者的脉络膜转移肿瘤的大小。方法:报告1例脉络膜转移癌患者,在随访中应用B超测量其肿瘤的高、基底和最大交叉截面积。结果:一位62岁华人老年妇女,已知为肺非小细胞癌患者,表现为右眼无痛性视物模糊。被诊为双眼脉络膜转移癌(右眼进展期,左眼初期),双眼视力良好。首次化疗后右眼肿瘤明显减小,但最后一轮化疗结束后6wk即出现增长。患者又进行了放疗和另一轮的化疗后右眼肿瘤大小没有变化。左眼肿瘤大小在随后的2a内没有变化。双眼维持着最佳矫正视力(右6/9,左6/6)。对右眼肿瘤的大小进行了连续B超测量评估。结论:超声检测在随访中是可重复的,并与右眼肿瘤临床表现相符。我们建议在治疗阶段应用B超对脉络膜肿瘤的大小进展或转归进行定量评估。

目的:评价准分子激光原位角膜磨镶术(LASIK)联合遮盖疗法治疗青少年屈光参差性弱视的疗效,并将其与传统光学矫正联合遮盖疗法的疗效进行比较。方法:回顾性病例对照研究,屈光参差性弱视患者19例,年龄10～17岁。A组包括患屈光参差性弱视的青少年10例,光学矫正联合遮盖疗法后,他们的视力不能改善。这些患者后接受LASIK联合遮盖疗法。B组包括年龄相匹配的屈光参差性弱视患者9例作为对照,他们适应光学矫正联合遮盖疗法。分析A组的术后视力,并与B组进行比较。结果:A组,术前平均球性屈光不正度数为-8.9±5.2D,术后为-1.9±2.0D;术前平均最佳矫正视力为0.25±0.18,治疗后提高至0.50±0.26。B组,治疗前平均最佳矫正视力为0.27±0.18,治疗后提高至0.50±0.28。两组治疗后最佳矫正视力相比较,无统计学差异。结论:对于经过传统的光学矫正联合遮盖疗法而不能提高视力的青少年屈光参差性弱视患者,LASIK为他们提供了一个可行的治疗方法,其治疗效果与传统疗法相当。

引用

World Journal of Gastroenterology 2007年第18期13卷 2581-2585页

AIM: To characterize and compare genotype profiles of H pylori strains isolated from patients with chronic gastritis and duodenal ulcer in western part of Turkey. METHODS: A total of 46 patients [30 chronic gastritis (CG) and 16 duodenal ulcer (DU)] who had undergone endoscopy because of dyspeptic complaints were studied. The antral biopsy specimens were evaluated for the presence of H pylori by rapid urease test and culture, and the genotype profiles were determined by real-time PCR. RESULTS: The cagA gene was observed in 43 (93.5%) isolates. The vacA s1m2 genotype was the predominant subtype, found in 63.3% and 68.7% of isolates in patients with CG and DU, respectively. Twenty (66.6%) isolates from patients with CG were iceA2 positive while the iceA1 was predominant in those with DU (68.8%). In terms of the association of the iceA alleles to other genes, both alleles were significantly associated with the cagA vacA s1m2 genotype. CONCLUSION: The prevalent circulating genotypes in CG and DU were cagA vacA s1m2 iceA2 and cagA vacA s1m2 iceA1 genotype, respectively. It was found that cagA vacA s1m2 genotype seems to be common virulence factors in both CG and DU while iceA alleles show specificity for gastroduodenal pathologies in this study.

<i>Mycobacterium vaccae</i>Immunization to Pregnant BALB/c Mice Ameliorated Lung Histopathology and Bone Marrow Eosinophila in Ovalbumin Sensitized Offsprings

引用

Open Journal of Immunology 2014年第2期4卷 31-41页

作者： Tunc Akkoc Cevdet Ozdemir Didem Yazi Ozlem Yesil Nerin nadir Bahceciler Isil Barlan Pediatric Allergy and Immunology Division School of Medicine Marmara University Istanbul Turkey

Context: One of the treatment strategies for atopic diseases is to skew immune response away from Th2 dominance by using Mycobacterial strains. Objective: We wanted to find out whether M. vaccae administration to pregnant mice had any preventive effect on the offsprings in the development of a murine asthma model. Materials and Methods: Pregnant BALB/c mice were divided into two groups;first group received heat-killed M. vaccae subcutaneously on 12th day of pregnancy and the latter group received PBS. After delivery, newborn mice of each group were further divided into two subgroups as M. vaccae/Ovalbumin (OVA), M. vaccae/control, PBS/OVA and PBS/ control. To establish experimental murine asthma model, mice were intraperitoneally sensitized and challenged intratracheally with Ovalbumin. We analysed airway histopathology, bone marrow eosinophil progenitors and splenic cell cytokine profiles of the offsprings. Results: Comparison of offsprings in M. vaccae/OVA group were not different than PBS controls with respect to thicknesses of airway epithelium, basement membrane, subepithelial smooth muscles and number of hyperplasic goblet cells as well as bronchial associated lymphoid tissue density and eosinophil progenitors in the bone marrow. Comparison of M. vaccae/OVA group to asthma model revealed significant differences and lower levels of OVA-induced IL-5. Conclusions: We propose that immunization of pregnant BALB/c with M. vaccae could prevent histopathological alterations in the airways related to the asthma model and down-regulates IL-5 secretion from splenocytes of offsprings.

World Journal of Gastroenterology 2014年第27期20卷 9116-9120页

作者： Menachem Moshkowitz Ohad Toledano Lior Galazan Aharon Hallak nadir Arber Erwin Santo Integrated Cancer Prevention Center and Department of Gastroenterology Tel-Aviv Sourasky Medical Center and Sackler Faculty of Medicine Tel-Aviv University

AIM: To assess the prevalence of colorectal neoplasms(adenomas, advanced adenomas and colorectal cancers) among Israeli military and commercial airline ***: Initial screening colonoscopy was performed on average-risk(no symptoms and no family history) airline pilots at the Integrated Cancer Prevention Center(ICPC) in the Tel-Aviv Medical Center. Visualized polyps were excised and sent for pathological examination. Advanced adenoma was defined as a lesion >10 mm in diameter, with high-grade dysplasia or villous histology. The results were compared with those of an age- and gender-matched random sample of healthy adults undergoing routine screening at the ***: There were 270 pilots(mean age 55.2 ± 7.4 years) and 1150 controls(mean age 55.7 ± 7.8 years). The prevalence of colorectal neoplasms was 15.9% among the pilots and 20.6% among the controls(P = 0.097, χ2 test). There were significantly more hyperplastic polyps among pilots(15.5% vs 9.4%, P = 0.004) and a trend towards fewer adenomas(14.8% vs 20.3% P = 0.06). The prevalence of advanced lesions among pilots and control groups was 5.9% and 4.7%, respectively(P = 0.49), and the prevalence of cancer was 0.7% and 0.69%, respectively(P = 0.93).CONCLUSION: There tends to be a lower colorectal adenoma, advanced adenoma and cancer prevalence but a higher hyperplastic polyp prevalence among pilots than the general population.

水稻(Oryza sativa L.)生长发育与其体内的激素调节密切相关,本研究从水稻野生型黎榆B(*** *** *** B)基因组中克隆了一个与激素调节相关的新基因OsJT1。生物信息学分析表明:水稻OsJT1基因cDNA全长650 bp、编码216个氨基酸;OsJT1蛋白的理论分子量为22.99 kD,等电点为7.68,是亲水性的稳定蛋白;OsJT1蛋白的二级结构中,9个α-螺旋,16个无规则卷曲,10个B折叠,5个β转角。本研究构建了融合表达载体(p Ca MV35S::OsJT1:EGFP),通过农杆菌介导法获得OsJT1过表达株系,性状分析表明:过表达株系的株高和结实率下降、叶宽增加,且结实率和叶片宽度与野生型差异均达到显著水平(p<0.05)。根据生物信息学及过表达转基因植株的表型分析内容,初步推断该基因可能与激素调节相关。
