The epidermal growth factor receptor is central to the growth, differentiation and the mobility of normal and cancer cells. Notably, EGFR plays an important role in non-small cell lung carcinoma development. Two known nucleotide variants in EGFR promoter at position -216 (G > T) and -191 (C > A) are known to influence promoter activity. The transcription factor Sp1 (Specificity protein 1) binds with higher affinity the T allele at position -216 which results in 30% increased transcriptional activity of EGFR. Sequencing of EGFR promoter region and exon 1 in 18 patients with pulmonary carcinoma revealed that -216 G/T variant was associated with 58.82% of NSCLC patients especially those with squamous carcinoma, with predominance of homozygote (T/T) variants. Strikingly, the -191C/A polymorphism was detected in 11.11% of patients having a pulmonary carcinoma with the predominance of homozygote (C/C) variants. The distribution analysis of the four haplotypes (G-C, G-A, T-C and T-A) and the diplotype (G-C/T-C) of -216G/T and -191C/A polymorphisms, revealed a clear predominance of T-C haplotype (216T-191C) in squamous cell carcinoma. The G-C and G-A haplotypes have a lesser distribution while the T-A haplotype is non-existent. The incidence of (G-C/T-C) diplotype is more important than the G-A haplotype in all the studied cases. Our results are strongly correlated with the data of Caucasian population.

AIM: To evaluate the efficacy and safety of botulinum toxin type A(BTX-A) in the management of patients with anismus. METHODS: An organized search of published literature was conducted using electronic databases including: Pub Med/MEDLINE, and Cochrane Central Register of Control ed Trials, also an internet-based search using "Google Scholar" service was conducted. Both comparative and observational studies were included. We excluded irrelevant articles, editorials, case reports, reviews, and meta-analyses. The studies that followed the patients less than 6 mo were excluded. Variables collected were demographic data of the patients, technique of BTX-A injection and number of sessions, short-term and longterm clinical improvement, post-injection changes in electromyography(EMG), defecography, manometry, and balloon expulsion test, and complications recorded after BTX-A ***: Seven studies comprising 189 patients were included in the review. The median age of the patients was 41.2 years and female-to-male ratio was 1.3:1. The median dose of BTX-A injected per procedure was 100 IU(range, 20-100 IU). Lateral injection was done in five trails and combined lateral and posterior injections in two trials. Three studies used endorectal ultrasonographyguided technique, one study used EMG-guided technique,whereas the remaining three studies used manual palpation with the index finger. The median percentage of patients who reported initial improvement of symptoms was 77.4%(range 37.5%-86.7%), this percentage declined to a median of 46%(range 25%-100%) at 4 mo after injection of BTX-A. Rates of improvement evaluated by balloon expulsion test, EMG, and defecography ranged between(37.5%-80%),(54%-86.7%), and(25%-86.6%), respectively. Fourteen(7.4%) patients developed complications after injection of BTX-A. Complication rates across the studies ranged from 0% to 22.6%. CONCLUSION: Initial satisfactory improvement of symptoms after BTX-A injection remarkably deteriorate

To observation, poisonous gases in the environment, Sensors with high selectivity, high response and low operating temperature are required. In this work, pure SnO2 nanoparticles was prepared by using a simple and inexpensive technique (hydrothermal method) without a template. Various confirmatory tests were performed to characterize SnO2 nanoparticles such as energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and Transition Electron Microscopy (TEM), during the detection of the gas, we found that pure SnO2 nanoparticles has a high selectivity for ethanol to 100 ppm at a low temperature (180°C) and a high response (about 27 s) and a low detection limit of 5 ppm, also it have response/recovery ti

In this work, we’ve made SnO2 flower formed with the aid of using easy test steps, and without cost, which is the hydrothermal approach and without a template. We have used a variety of techniques to characterize SnO2 flower-shaped by (SEM, TEM, XRD, BET and XPS) instruments. Confirmatory tests carried out have proven that the surface of the tetragonal structure of SnO2 has a rough surface which makes it excellent for its gas-sensing properties. The gas detection test of SnO2 flower-shaped proved that it possesses the selectivity of formaldehyde gas (about 30), the optimum operating temperature of the sensor is 220°C, and also the sensor has a high response time and recovery time is (5 s and 22 s) to 100 ppm, respectively. Particularly, the sensor has an obvious response value (2) when exposed to 5 ppm formaldehyde. As well, the mechanism of gas-sensing was also discussed.

本文提出了一种不同浓度功能化多壁碳纳米管(f-MWCNTs)与聚乙烯醇(PVA)共混制备交联纳米复合膜的方法。由于MWCNTs的水溶性差、表面化学性质差、不具有柔性以及自身不能形成薄膜复合材料,这些缺点限制了其各种的应用。因此,为了改善它们的物理性能,特别是在环境应用方面提供更好的潜力,它们的改性和PVA 的混合促进了这一过程。这就汇集了这两种材料的优点,形成疏水膜,能够从废水中捕获重金属、农药、细菌和真菌,具有良好的可循环利用性。柠檬酸交联剂是用来支持f-MWCNTs/ PVA 直接转换成纳米复合材料,通过培养皿和干燥60 ℃。所得数据表明,将f-MWCNTs浓度提高到8%可以提高重金属的去除效率。此外,随着f-MWCNTs 浓度的增加,农药捕获量也在增加。对纳米复合材料中f-MWCNTs的抑菌活性和真菌种类进行了评价,结果表明,在高负载的f-MWCNTs作用下,纳米复合材料的抑菌活性明显增强。这些结果验证了纳米复合膜作为废水处理的一部分的前景和经济可行的技术。

目的:报告16例颅内结核瘤患者的临床、影像学表现及抗结核治疗的结果。设计:本文共纳入苏丹Khartoun市全国神经系统疾病中心连续观察的16例脑结核瘤患者。诊断则依据其临床、头颅影像学特征及对抗结核治疗有效等方面。本组中共有7例具有脑组织或脑外组织的病理组织学资料。结果与结论:本组病例最常见的临床表现是头痛(100%)、全身性抽搐(68.7%)及偏瘫(56.2%)。头颅横断面电子计算机体层摄影(CT)/核磁共振成像(MRI)显示单个或多个明显增强的病变及病灶周围水肿。经抗结核治疗后,多数存活患者(13/15)病变完全吸收。病变部分吸收与就诊延迟、颅内多个大病灶及晚期粟粒性结核病有关。我们主张对颅内结核瘤,即使是拟诊病例,应早期经验性试用抗结核治疗,尤其在结核病高发地区。

Bacterial endocarditis following atrial septal defect closure using Amplatzer device in a child is extremely rare. We report a 10-year-old girl who developed late bacterial endocarditis, 6 years after placement of an Amplatzer atrial septal occluder device. Successful explantation of the device and repair of the resultant septal defect was carried out using a homograft patch. The rare occurrence of this entity prompted us to highlight the importance of a closed long-term follow up, review the management and explore preventive strategies for similar patients who have multiple co-morbidities and a cardiac device. A high index of suspicion is warranted particularly in pediatric patients.
