Alhajri Fahad Thamer Almutairi Ashwag Hassan Abdelmajed Fatima Ibrahim Abdalla Yousra Bala Babkir Abdullah Mosab mohamedelamineltaib Ahmed Faroug Ahmed Abdelaal mohamed Ahmed Mukhtar Mowafag Bushra Galaleldin Elsayed Marwa mohamed Ahmed Elkhidir Babikir Nihal Altayeb abdallah Selma Mohammed Abdelgadir Elhabeeb Department of Obstetrics and Gynecology College of Medicine Najran University Najran Saudi Arabia Najran Armed Forces Hospital Najran Saudi Arabia

Background: The gram-positive, beta-hemolytic, and chain-forming Group B Streptococcus (GBS), commonly known as Streptococcus agalactiae, may asymptomatically invade the human gastrointestinal and vaginal tracts. However, GBS may become very invasive and pathogenic to the mother and baby during pregnancy, having negative effects. Study Aim: This study aims to investigate the pregnancy outcomes of women who tested positive for genitourinary GBS infection during pregnancy in Najran, Saudi Arabia. Methods: Data was collected retrospectively from patient files in Armed Forces Hospital, Najran, Saudi Arabia. Data collected were entered to a Microsoft Excel sheet, then imported and analysed using the Statistical Package for Social Sciences. Results: The study included 272 women of whom 66.5% were 31 to 45 years old. Gestational diabetes was diagnosed in 8.5% of the sample, 71.7% had a normal spontaneous vaginal delivery (NSVD), 1.8% had previous abortions, and 27.2% of new-borns were admitted to the NICU after delivery. There was a significant association between NICU admissions and women employment status (p = 0.001), gravidity (p = 0.001), parity (p = 0.001), history of abortions (p = 0.001), medical conditions (p = 0.049), and mode of delivery (p = 0.049). Conclusion: According to the findings of our study, GBS infection during pregnancy is associated to more NICU admissions. NICU admissions were significantly correlated with gestational diabetes, hypertension, and hypothyroidism in mothers but not with intrapartum antibiotic use.

Introduction: Nowadays the more accepted surgical option for treating early breast cancer is breast conserving surgery. The main challenge in this type of surgery is to get free safety margins without need of second surgical operation, so many breast surgeons have started to depend on intraoperative frozen sections to ensure free safety margins. Aim of work: To assess our policy that we prefer to depend on intraoperative frozen section analysis to get free safety margin in breast conserving surgery from the 1st surgery, and its oncologic outcome. Patients and Methods: This is a retrospective study conducted in Oncology Center—Mansoura University (OCMU), where the data of 219 patients with breast cancer, who were managed by breast conserving surgery with intraoperative frozen section analysis of the safety margins, was analyzed. Results: The intraoperative frozen section analysis of safety margin was negative from the start in 183 (83.6%) patients, while it was positive in 36 patients (16.4%). Intraoperative decision of margin re-excision was applied for 29 patients (13.2%) in order to reach negative margin, modified radical mastectomy was offered for 4 patients (1.8%), while nipple sparing mastectomy with immediate breast reconstruction using latissimus dorsi flap was offered for 3 patients (1.4%). The postoperative paraffin results were typical with intraoperative frozen section analysis results in 216 patients (98.6%) and different results were obtained in only 3 patients (1.4%) who were managed by modified radical mastectomy in a second operation. Only 4 patients had local recurrence (1.8%) during the period of follow-up duration which was ranged from 1 to 86 months with mean ± SD (22.3 ± 14.1). Conclusion: The intraoperative frozen section analysis of safety margins in breast conserving surgery has very high-rate typical results with the paraffin section analysis and it is very helpful in decreasing the rate of second surgical operation in cases of infiltrated m

Indentation Creep Behavior and Microstructure of Cu-Ge Ferrites

引用

Materials Sciences and Applications 2011年第8期2卷 1076-1082页

作者： Hesham Mohaned Zaki Ali mohamed Abdel-Daiem Yahia Ibrahim Swilem Farid El-Tantawy Fahad Masoud Al-Marzouki Ahmed abdallah Al-Ghamdi Saleh Al-Heniti Farag Said Al-Hazmi Talal Sadaka Al-harbi 不详

Cu-Ge ferrite was prepared using the standard ceramic method. The creep rate of polycrystalline Cu1+xGexFe2-2xO4 ferrite has been measured as a function of time at room temperature. It is found that the indentation length increases with the increase of both time and applied load. A regime of individual creep curves is observed for the first and second stages. It is not possible to record the third stage of the curve as usually happened in an ordinary creep test, because fracture of the samples does not occur. The slope is found to increase with increasing germanium and copper content in the steady state region. The high value of n (stress exponent factor) indicates that the dislocation creep is the dominate mechanism. The porosity arrangements developed within the specimens were examined using optical microscope. The results are discussed with regard to models describing the role of the steady state creep rate of metals. The morphology of the samples shows that the porosity is increased by increasing both copper and germanium ions.

引用

材料科学与工程（中英文A版） 2015年第1期5卷 65-68页

作者： mohamed Shaban Hany Hamdy Heba abdallah Lamiaa Said Ahmed Abdel khalek Nanophotonics and Applications Lab Department of Physics Faculty of Science Beni-Suef University Beni-Suef 62514 Egypt Engineering Research Division Chemical Engineering & Pilot Plant Department National Research Center Dokki 12311 Egypt Department of Chemistry Faculty of Science Beni-Suef University Beni-Suef 62514 Egypt

In this work, PES (polyethersulfone)/TiO2 nanotubes membranes were fabricated by a simple and cheap method. The TiO2NTs (titanium dioxide nanotubes) are prepared by the hydrothermal method, the tubes had a narrow size distribution with an average inner diameter of 3-5 nm and outer diameter of 10-13 nm. TiO2NTs blended PES membranes are prepared by phase inversion method with different nanotubes percentage (0.18%-0.85%). The morphology of PES membrane was obviously affected by the addition of TiO2NTs. The prepared membranes were applied on a vacuum desalination system and the desalination results showed that the salt rejection % and permeate flux of the membrane are enhanced through the addition of TiO2NTs. The membrane with higher (0.85%) TiO2NTs content resulted in a decrease of salt rejection % because of the defective membrane structure.

作者： Sanaa Ahmed Ali Maha Zaki Rizk Nabawia Ali Ibrahim Mohga Shafik abdallah Hayat mohamed Sharara Magda mohamed Moustafa Department of Theraputical Chemistry National Research Centre Department of Pharmacognosy National Research Centre Department of Chemistry Faculty of Science Helwan University

AIM: To investigate the role of Cupressus sempervirens (C. sempervirens) and Juniperus phoenicea (J. phoe-nicea) extracts as therapeutic effect against CCl4 with biochemical, histopathological evaluations. METHODS: A single intraperitoneal dose of 10% CCl4 in olive oil (1 mL/kg body weight) was administered to a group of female Wister rats, sacrificed after 24 h (as the injury group). The other groups were given CCl4 as de-scribed above and divided as follows: two groups of ten rats each were orally administered either J. phoenicea extract or C. sempervirens extract three times per week for six weeks and a further group administered CCl4 was left for six weeks to allow self-recovery. At the end of experiment, the rats from all groups were sacrificed for sampling and for biochemical and histological analysis. RESULTS: Remarkable disturbances were observed in the levels of all tested parameters. On the other hand,rats injected with the toxic agent and left for one and a half month to self recover showed moderate improve-ments in the studied parameters while, treatment with both medicinal herbal extracts ameliorated the levels of the disturbed biochemical parameters. The group treated with J. phoenicea extract showed a remarkable improvement in comparison to the CCl4 treated group. The C. sempervirens group revealing an even more re-markable effect showing histopathological liver& kidney profiles close to those of the control ***: C. sempervirens and J. phoenicea leaf extracts show a remarkable effect in enhancing liver and kidney functions and may thus be of therapeutic potential in treatment hepatotoxicity and nephrotoxicity.

The Golden Jackal (Canis aureus Linnaeus, 1758), which belongs to the Canidae family, is an opportunist carnivore in the Gaza Strip (365 square kilometers). The current study aims at giving notes on the occurrence and some ecological aspects of the species in the Gaza Strip, Palestine. The study, which lasted 14 years (2007-2020), is descriptive and cumulative in its style. It was based on frequent field visits, direct observations and meetings and discussions with wildlife hunters, farmers and other stakeholders. The findings of the study show that Gazans are familiar with the Golden Jackal to the extent that a Gazan family holds the Arabic name of the animal, which is “Wawi”. The Golden Jackal was sometimes encountered and hunted in the eastern parts of the Gaza Strip, which are characterized by the presence of wilderness areas, intensive agriculture, poultry pens and solid waste landfills. Like other a few mammalian faunas, the adult Golden Jackals enter the Gaza Strip through gaps in or burrows beneath the metal borders separating the Gaza Strip from the rest of the Palestinian Territories and Egypt. Gaza zoos were found to harbor tens of Golden Jackals trapped or hunted by clever wildlife hunters using different means such as wire cages known locally as “maltash” and foothold traps with metal jaws that may cause lesions to the trapped animals. Poisoning and shooting were also common methods used to control the jackals and other carnivores causing harm to agriculture and livestock. The animal was known among the Gazans as an omnivore, feeding on wild and domestic animals in addition to plant materials, garbage and carrions. In conclusion, the study recommends the need to raise ecological awareness to preserve the Golden jackal and to adopt safe control measures for jackals and other carnivores, including the construction of protective fences for agricultural fields and animal pens.

World Journal of Gastrointestinal Endoscopy 2016年第10期8卷 409-417页

作者： mohamed E Abd Ellatif Haitham Alfalah Walid A Asker Ayman E El Nakeeb Alaa Magdy Waleed Thabet mohamed A Ghaith Emad abdallah Rania Shahin Asharf Shoma Ibraheim E Dawoud Ashraf Abbas Asaad F Salama Maged Ali Gamal Department of Surgery Mansoura University Hospital Consultant of Bariatric Surgery King Saud Medial City (KSMS) Gastroenterology Surgical Center Mansoura University Department of Anesthesia Mansoura University Hospital Department of Clinical Pathology Benha University Hospital Department of Surgery Jahra Hospital

AIM: To study the preoperative and postoperative role of upper esophagogastroduodenoscopy(EGD) in morbidly obese patients. METHODS: This is a multicenter retrospective study by reviewing the database of patients who underwent bariatric surgery(laparoscopic sleeve gastrectomy, laparoscopic Roux en Y gastric bypass, or laparoscopic minigastric bypass) in the period between 2001 June and 2015 August(Jahra Hospital-Kuwait, Hafr Elbatin Hospital and King Saud Medical City-KSA, and Mansoura University Hospital- Egypt). Patients with age 18-65 years, body mass index(BMI) > 40, or > 35 with comorbidities after failure of many dietetic regimen and acceptable levels of surgical risk were included in the study after having an informed signed consent. We retrospectively reviewed the medical charts of all morbidly obese patients. The patients' preoperative data included clinical history including upper digestive symptoms and preoperative full workup including EGD. Only patients whose charts revealed weather they were symptomatic or not were studied. We categorized patients accordingly into two groups; with(group A) or without(group B) upper digestive symptoms. The endoscopic findings were categorized into 4 groups based on predetermined criteria. The medical record of patients who developed stricture, leak or bleeding after bariatric surgery was reviewed. Logestic regression analysis was used to identify preoperative predictors that might be associated with abnormal endoscopic findings. RESULTS: Three thousand, two hundred and nineteen patients in the study period underwent bariatric surgery(75% LSG, 10% LRYDB, and 15% MGB). Mean BMI was 43 ± 13, mean age 37 ± 9 years, 79% were female. Twenty eight percent had presented with upper digestive symptoms(group A). EGD was considered normal in 2414(75%) patients(9% group A vs 66% group B, P = 0.001). The abnormal endoscopic findings were found high in those patients with upper digestive symptoms. Abnormal findings(one or more) were fo
