Structural and Tectonic Evolution of el-Faiyum Depression,north Western Desert,Egypt Based on Analysis of Landsat ETm+,and SRTm Data

Journal of Earth Science 2011年第1期22卷 75-100页

作者： Timothy m Kusky talaat m Ramadan mahmoud m Hassaan Safwat Gabr Three Gorges Research Center for Geo-hazard State Key Laboratory of Geological Processes and Mineral Resources China University of Geosciences The Geological Applications and mineral Resources Division National Authority for Remote Sensing and Space Sciences (NARSS) Cairo Egypt

False color Landsat ETm＋（bands 7, 4, 2 in RGB） and SRTm images of the EI-Faiyum depression, Egypt, highlights major nE-SW faults and other lineaments trending nW-SE and n-S. Airborne magnetic data reveal some E-W subsurface faults which are not recognized on Landsat ETm＋ and SRTm images. Ratio images （5/7, 3/1, 4/3） and （5/7, 5/1, 4） were used for lithological discrimination of different rock types. The EI-Faiyum area is occupied by sedimentary rocks of middle Eocene, Upper Eocene, Oligocene, Lower miocene, Pliocene, Pleistocene and Holocene. Understanding the structural regime of EI-Faiyum depression in the Western Desert of Egypt is significant in relation to the neotectonics of the nile Delta and to the development of new communities west of the delta. The area is covered by Late Cretaceous, middle to Late Eocene deposits, Oligocene deposits （comprising fluviatile sediments and basalt sheets） and Pliocene and Quaternary alluvium and sand deposits. new geological and structural maps were prepared at a scale of 1 ： 100 000 using Landsat ETm＋ and SRTm images coupled with extensive field work. The major structural trends are E-W, EnE, nS and nW--the same trends observed elsewhere in north Africa from nW Sudan to nE Egypt including north and central Sinai. EI-Faiyum depression is a structurally-controlled tectonic basin, marked by northeast-striking faults along its northern margin. These faults are parallel to similar faults of the Syrian arc fold belt, which includes a group of related faults, folds, push-up structures, and basins. Qarun Lake is located in the northern part of EI-Faiyum depression, at a right-step between two strands of the nE striking fault system. We have suggested elsewhere that EI-Faiyum depression is a pull-apart basin related to extension between these mismatched strands of strike-slip faults. The E-W structures are probably related to the relative motion between south Europe and north Egypt and closure of the neotethys. The continuation of t

The data were categorized into three periods, including early period(1993-2002), middle period(2003-2012), and late period(2013-2017).RESULTS The frequency showed PD was increasingly performed after the year 2000. With time, elderly, cirrhotic and obese patients, as well as patients with uncinate process carcinoma and borderline tumor were increasingly selected for PD. The median operative time and postoperative hospital stay decreased significantly over the periods. Hospital mortality declined significantly, from 6.6% to 3.1%. Postoperative complications significantly decreased, from 40% to 27.9%. There was significant decrease in postoperative pancreatic fistula in the second 10 years, from 15% to 12.7%. There was a significant improvement in median survival and overall survival among the *** Surgical results of PD significantly improved, with mortality rate nearly reaching 3%. Pancreatic reconstruction following PD is still debatable. The survival rate was also improved but the rate of recurrence is still high, at 36.9%.

HER-2/neu Status in Gastric Carcinomas in a Series of Egyptian Patients and Its Relation to Ki-67 Expression

引用

Open Journal of Pathology 2015年第4期5卷 101-113页

作者： Saba el-Gendi Iman talaat mona Abdel-Hadi Department of Pathology Faculty of Medicine Alexandria University Alexandria Egypt

Objective: HER-2/neu status in gastric carcinomas (GCs) has not been studied before in the Egyptian population. materials and methods: Seventy-three GCs were evaluated for the expression of HER-2/neu and Ki-67 using immunohistochemistry (IHC). Fluorescence in situ Hybridization (FISH) was done for HER2/neu IHC score 2+ cases. Results: Out of the 73 gastric carcinomas, 23 (31.5%) were score 0, 17 (23.3%) were score 1+, 23 (31.5%) were score 2+, and 10 (13.7%) were score 3+. FISH analysis revealed that the HER-2/neu gene was amplified in 11 out of the 23 cases (47.8%) scored 2+ by IHC. Therefore, the overall HER-2/neu positivity rate was 28.8% and it was significantly associated with higher T-stage and lymphovascular invasion (LVI). The Ki-67 expression rate ranged between 10% and 100%, with 84.9% of the cases (n = 62) featuring high Ki-67 scores. High Ki-67 score was significantly associated with male sex, tumor grade, and number of positive nodes. HER-2/neu protein expression correlated significantly with Ki-67 score. Twenty tumors showed combined HER-2/neu positivity and high Ki-67 score and were significantly associated with higher T-stage and occurrence of LVI, implying a more aggressive behavior. Conclusions: The rate of HER-2/neu positive GCs in our series simulates universal rates, thereby mandating routine evaluation of HER-2/neu status in all GCs submitted to our laboratory to benefit from trastuzumab therapy. Further studies on a larger number of GCs are required to prove that the concurrent HER-2/neu positivity and high Ki-67 score are markers of worse prognosis.

Detection of Polymorphisms of DnA Repair Genes (XRCC1 and XPC) in Prostate Cancer

引用

Journal of Cancer Therapy 2013年第10期4卷 1499-1505页

作者： Amani Fouad Sorour Iman mamdouh talaat Tamer mohammed Abou Youssif mohamed Adel Atta Department of Clinical Pathology Faculty of Medicine Alexandria University Alexandria Egypt Department of Genitourinary Faculty of Medicine Alexandria University Alexandria Egypt Department of Pathology Faculty of Medicine Alexandria University Alexandria Egypt

Prostate cancer is a common disease with a multifactorial and complex etiology. It is the most common male malignancy and the second leading cause of death in many countries. The widespread use of PSA testing has increased the detection of this cancer at earlier stages, although this diagnostic method has proved to be insufficient to identify the disease. DnA in most cells is regularly damaged by endogenous and exogenous mutagens. At least four main partially overlapping damage repair pathways operate in mammals. Common polymorphisms in DnA repair genes may alter protein function and an individual’s capacity to repair damaged DnA;deficits in repair capacity may lead to genetic instability and carcinogenesis. In the present study, we investigated the genotypic distribution of XRCC1 and XPC polymorphisms and its association with prostate cancer risk, pathological staging and Gleason’s scoring. The present study was conducted in the departments of Clinical Pathology, Pathology, and Urology Faculty of medicine, Alexandria University-Egypt. A total number of 50 patients with pathologically confirmed prostate cancer and 50 age-matched control subjects were enrolled in this study. The diagnosis was made on the basis of histopathological findings, following radical prostatectomy or transurethral resection of the prostate (TURP). Genomic DnA was extracted from peripheral blood using QIAamp blood DnA isolation kits. PCR followed by enzymatic digestion of the PCR products for (XRCC1, XPC) was used for the genotyping of these polymorphisms. Statistical analyses were performed using SPSS statistics version 20. The genotype frequencies of the studied polymorphisms in all the samples (n = 100), PC patients (n = 50) and healthy controls (n = 50) were consistent with the Hardy-Weinberg equilibrium distribution (p-value > 0.05). There was no statistical difference in the genotypes of the XRCC1 Arg399Gln and XPC Lys939Gln between cases and controls. The “Gln” allele frequency of XPC L
