Background: Breast cancer (BRC) is the second most common cancer in the world, the most frequent cancer among women, and the leading cause of cancer death in females worldwide. Aims to study the pattern of breast cancer in all the patients who were presented to the Oncology Department at Benghazi Medical Center (BMC) from various parts of eastern Libya from the 1st of January 2016 to the 31st of December 2018. Subjects and Methods: This is a retrospective, cross-sectional and histopathological study to determine the frequency of the (BRC) malignancy type, in addition to stages and age groups. The data was collected from the Oncology Department at Benghazi Medical Center which receives cancer patients from Benghazi and the whole eastern part of Libya. Data was also collected from the Pathology Department at the Faculty of Medicine, University of Benghazi and Alnon, a private laboratory. There were 515 registered patients with breast cancer including demographic and clinic-pathological data. The data was analyzed using the SPSS Program Version 20. Results: Out of 515 breast cancer patients registered at the Oncology Department (BMC), geographically 66% were from Benghazi, followed by Albaida at 9.1%. Conclusion: The majority of cases were between 46 and 56 years old. Invasive ductal carcinoma was diagnosed among most of the cases, (Grade II and stage III. Most of the breast cancer cases collected from BMC were from Benghazi, frequency is higher among the age range (46-56) and most cases were Stage III, and grade II. Invasive ductal carcinoma is the most predominant histopathological type. Most cases were HER2 negative, ER positive and PR positive, and most cases had Ki-67 levels (21- 40%).

Twenty-five samples were collected at 30 cm intervals from the studied cored interval within the limestone unit (AII) reported at IODP Site U1376 on Burton Guyot. The purpose of this research is to examine and identify the coral and algae suites in the studied core concerning sea level fluctuation during the Eocene time. This reef is isolated by being between two volcanic units in the Southwest Pacific Ocean. Eleven biofacies units have been established based on the fabric of the grains. The biofacies units are as follows; Algal-coral grainstone, foraminiferal algal-coral grainstone (Alabaminabed), foraminiferal algal-coral packstone to grainstone (Heterostegina bed), algal-coral grainstone, foraminiferal algal boundstone, foraminiferal algal grainstone (Lagena bed), foraminiferal algal grainstone (Cibicidoides micrus-bed), foraminiferal algal boundstone to grainstone, foraminiferal algal-coral grainstone, algal echionoidal packstone, and foraminiferal algal coral wacke-packstone. This is the first study to use both algae and coral in differentiating the units mentioned above. The only coralline red algae recognized in the samples is Lithothamnion camarasae. This species is a good indicator of the warm climatic conditions during the middle-late Eocene. The only species of coral found in these units is Isopora togianensis, a scleractinian reef builder. The high percentage of algae compared to coral indicates a climatic change from a greenhouse to an icehouse climate. The faunal trend during this time also indicates a tectonic change.

هدفت هذه الدراسة إلى التعرف على محددات هيكل رأس المال وأثرها على السلوك التمويلي للمشروعات الصغرى في ليبيا. ركزت الدراسة على عدد من المحددات باعتبارها متغيرات مستقلة وهي: حجم المشروع، الأصول الثابتة، الربحية، النمو ومدى تأثيرها على المتغير التابع (هيكل رأس المال) مقاسا بإجمالي الديون، الديون طويلة الأجل، الديون قصيرة الأجل. استخدمت الدراسة المنهج التحليلي، وقد تكونت عينة الدراسة من 31 مشروعاً التي توفرت فيها البيانات المطلوبة لقياس المتغيرات وذلك عن الفترة المالية (2015-2017)، وتحليلها ببعض الاساليب الإحصائية كمعامل الارتباط وتحليل الانحدار، وتحليل التباين. أظهرت نتائج الدراسة وجود تأثير للمحددات (الخصائص) على هيكل رأس المال مقاساً بإجمالي الديون والديون قصيرة الأجل. كما توصلت الدراسة إلى أن حجم المشروع له تأثير طردي على إجمالي الديون والديون قصيرة الأجل، أما الاصول الثابتة فلها تأثير طردي على الديون طويلة الأجل وعكسي على إجمالي الديون والديون قصيرة الأجل، بينما ترتبط الربحية بعلاقة عكسية مع الديون قصيرة الأجل. عليه يمكن القول إنه نظرية الالتقاط التدريجي، أكثر من غيرها، تساهم بشكل مقبول في تفسير السلوك التمويلي للمشروعات الصغرى في ليبيا.

This study is an attempt to describe some aspects relating to the blood cells of one of Libya's wildlife animals, the long-eared hedgehog (Hemiechinus auritus). The investigation focused on the morphology of the blood cells in newborn and adult animals that were obtained from the city of Benghazi. Four one-day-old hedgehoglets and 20 adult hedgehogs were utilised to prepare stained blood smears. Structural features of blood cells of both young and adult animals did not show prominent variations from each other. Neutrophils nuclei had a band and multilobulated appearance. The maximal number of nuclear lobes reached seven in the newborn hedgehogs and eight in the adult and the joining threads between the lobes were mostly very obvious. The Barr body could not be observed in neutrophils of the female animals. Non-lobulated nuclei were encountered in the eosinophils of the adult animals, whereas the nuclear trilobulation could be noticed in the eosinophils of both groups of hedgehogs. Basophils of the newborn hedgehogs showed large irregular nuclei, whereas those of the adults had partially divided indented nuclei. Small, medium and large lymphocytes could be observed in blood films of the newborn and adult animals. However, the majority of the lymphocytes were small in size. Eccentrically located nuclei with kidney-shaped, horseshoe, oval and round appearances were recorded in monocytes of both groups of animals. Platelets of the newborn and adult hedgehogs were non-nucleated and had round to oval shapes. A centrally located dark area surrounded by a less dense area was obvious. The discoid non-nucleated erythrocytes had a biconcave appearance in both groups of hedgehogs.

Background: Hepatitis B virus is a common cause of viral hepatitis infection. Since the impact of immunization and other prevention programs, the number of countries previously categorized as high prevalence is now estimated to have a population seroprevalence below 8%. Aim: This study was done to evaluate the vaccine efficacy and measure the response of children to the vaccine after the first dose of the HBV vaccine in Benghazi-2022. Subjects and Methods: A descriptive study of a cross-sectional design was conducted in Benghazi vaccination centers; blood samples were collected from 43 children, and the samples were taken during vaccination visits or at OPD clinics. Anti-HBs titer was estimated by ELISA. Results: The ages of the infants in the study ranged from 1-2 months. The mean Anti-HBs titer after receiving zero doses was 18.9 (±23.6) IU/L. The number of protective children was 29 out of 43 (67.4%) at zero doses. Conclusion: This study showed that the birth dose (zero dose) gave a good protective level in infants as seroprotection was 67.4% after this dose.

Background: Gastric cancer is considered globally a major health issue. Many studies have shown that adenocarcinomas represent about 90% of all gastric cancers. It is subdivided into two main histological types; intestinal and diffuse. Aim: The aim of this study is to determine the frequency and the histopathological characteristics of gastric adenocarcinoma among patients of the National Cancer Center of Benghazi in the period of 2020-2021. Subjects and methods: A retrospective study of 52 gastric cancer cases from the archive of the National Oncology Center in Benghazi and data was analyzed with SPSS. Results: In the research period between January 2020 to May 2021, the total number of patients with confirmed gastric cancer was 52 cases. The patients' ages were between 29 to 86 and the mean age was 63. Thirty-one (31) cases were male (59.6%) and twenty-one (21) were female (40.4%). Diffuse adenocarcinoma was predominant over the intestinal type (25% and 19.2 % respectively). 48% of the cases were of undetermined type and 3.8% were gastrointestinal stromal tumors. Most of the cases presented at stage IV. Conclusion: The histopathological picture of gastric cancer in our study was similar to a previously published study done in Benghazi with male predominant and diffuse adenocarcinoma as the more common cancer. Some risk factors are attributed such as infection with H pylori, smoking and anemia.

هدفت هذه الدراسة إلى تقييم إنبات بذور نباتي البصل Allium cepa والجرجير Eruca sativaفي بيئة ملوثة بمخلفات البطاريات المنزلية الجافة، وذلك من خلال ري بذور النباتات المدروسة بتراكيز مختلفة من مستخلصات التربة ومخلفات البطاريات الشاهد (ماء مقطر)، 0 (مستخلص التربة)، 5، 10، 15%. أظهرت النتائج عدم وجود فروق معنوية لتأثير الري بمخلفات البطاريات على النسبة المئوية لابنات بذور الجرجير حيث وصلت جميع المعاملات إلى نسبة إنبات 100% منذ اليوم السابع للإنبات، فيما وجدت فروق معنوية عالية جداً عند مستوى 0.05% على إنبات بذور البصل، وكذلك أدت المعاملات إلى انخفاض نمو البادرات في المراحل الأولى للإنبات ثم زاد نموها في كلا النباتين بزيادة تراكيز المعاملات، حيث بلغت أعلى القيم للجذير 1.9، 13.9سم وللرويشة 37، 67سم لنباتي الجرجير والبصل على التوالي، مما يدل على قدرة نمو النباتين في بيئات ملوثة بمخلفات البطاريات وما تحتويها من عناصر ثقيلة، وإمكانية امتصاصها وانتقالها إلى الكائنات المستهلكة.

Metals suffer from corrosion by the surrounding fluids, which causes great economic losses and bad environmental effects, especially in oil pipelines or reservoirs. Therefore, attention was paid to finding cheap and environmentally friendly materials that can resist and reduce corrosion. Among the widely used materials, expired medicines have proven their effectiveness due to their richness in chemicals with Polar functional groups that have the ability to be adsorbed on the surface of the metal or oil pipelines, and the expired drugs that were used in this research paper are Chlorhexidine (Ch.) and Rhuvex (Rh.), and corrosion inhibition is tracked by the method of loss of balance and by the voltage method. The results showed that (Ch.) is more efficient than (Rh), whether by weight loss method or by the Potentiometric method, and that (Rh.) is more stable at high temperatures, and this was confirmed by the Arrhenius curves, state and transition, activation energy calculation, change in enthalpy and change in entropy, and the potentiometric method showed the extent of voltage change with time for each A concentration of expired drug concentrations for two hours, and that the voltage increases with increasing concentration, which indicates a high ability of the inhibitor to adsorb to the metal.
金属受到周围流体的腐蚀，造成巨大的经济损失和恶劣的环境影响，尤其是在石油管道或油库中。因此，人们开始关注寻找能够抗腐蚀和减少腐蚀的廉价环保材料。在广泛使用的材料中，过期药品由于富含具有极性官能团的化学物质，具有吸附在金属或石油管道表面的能力，因此证明了其有效性。本研究论文中使用的过期药品是洗必泰（Ch.）和鲁维克斯（Rh.），并通过失衡法和电压法跟踪了其缓蚀效果。 结果表明，无论是采用失重法还是电位法，（Ch. ）都比（Rh. ）更有效，而且（Rh.)在高温下更稳定，这一点通过阿伦尼乌斯曲线、状态和转变、活化能计算、焓的变化和熵的变化得到了证实。电位法显示了每 A 浓度的过期药物浓度在两小时内电压随时间的变化程度，电压随浓度的增加而增加，这表明抑制剂对金属的吸附能力很强。
