Abstract: This research aims at exploring the potentiality of utilizing Landsat 8 in integration with the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data for lithological mapping of the Wadi Hamad area, North Eastern Desert of Egypt. Geological mapping in the Eastern Desert is impeded by difficult accessibility. By the use of Band combination, Principal Component Analysis (PCA) and Spectral ratioing of selected bands of Lands at 8 and ASTER data of the area, in synergy with geological field observation has proved effective in resolving geological mapping problems in the region. The validation mechanism was based on both matching interpreted lithological boundaries to the previously published geologic maps, field data and laboratory microscopic examinations of selected samples collected from the different exposed rocks in the area of study.

Abstract: Delaying childbearing to a later age has increased the number of women with cancer in pregnancy. Little information on the effects of prenatal exposure to chemotherapy on the fetus, prompted us to study the transplacental transport of chemotherapeutic agents and its effect on the liver of offsprings. Doxorubicin (DOX) an anthracycline antibiotic, which is widely used as an antineoplastic drug in the treatment of various solid tumors, especially breast cancer, has been shown to induced hepatotoxicity. The aim of the present study was to investigate the possible protective effect of Alpha- lipoic acid (ALA) on the postnatal developing liver of albino rats whose mothers treated with DOX. The pregnant mothers were divided into four main groups. G1 (control), G2 (ALA treated group), G3 (DOX treated group) and G4 (ALA+DOX treated group). After delivery, liver of newborn from all groups at the 1^st and 7^th days were collected and processed for histological examination. Monitoring of micronuclei formation and chromosomal aberrations assays in rat liver were also done. The liver from G3, showed various degenerative changes especially on the liver of the 7^th day. The hepatotoxicity of the offspring suggested transplacental passage of doxorubicin. The pretreatment with ALA in G4 showed ameliorating effect on the hepatotoxicity induced by DOX. The cytogenetic results revealed that groups treated with ALA+DOX showed a significant reduction in the frequency of micronuclei formation as well as of chromosomal aberrations. Conclusion: from the results of the present study, it could be concluded that the pretreatment by alpha-lipoic could attenuate the DOX induced hepatotoxicity of newborn albino rat.

Abstract: This trial was performed to study the effects of addition and/or substitution of various form of zinc sources (inorganic, organic and nano zinc) on performance, economic efficiency, blood metabolites and zinc concentration in tissue (breast muscle and liver) of broiler chickens. A total of 525 day old chicks were divided into seven groups with five replicates per group (75 chicks/group; 15 chicks/replicate). birds fed on 7 experimental diets; group 1: control basal diet without zinc supplement, group 2: 40 ppm inorganic Zn (ZnSO₄), group 3: 40 ppm organic Zn methionine (Zn-Met), group 4: 40 ppm nano zinc oxide (nano ZnO), group 5: 20 ppm ZnSO₄+20 ppm Zn-Met, group 6: 20 ppm ZnSO₄+20 ppm nano ZnO, group 7: 20 ppm Zn-Met+20 ppm nano ZnO. This experiment was extended for 6 weeks. Individual body weights and feed residues were measured weekly. At the trial end, collect blood and tissue samples after slaughter five birds/group. The overall BW, BWG and FCR were significantly improved in the Zn supplemented groups. Return, net profit or partial and collective efficiency measures were significant different between all group. There was significant increase in concentrations of serum total protein, HDL-cholesterol and ALP in groups supplemented with Zn. Furthermore, there was significant increase in serum; breast and liver zinc concentration in experimental groups. Compared to inorganic-Zn form, supplementation and/or substitution with organic-Zn and/or nano-Zn form had a positive influence on the overall performance, Zn concentration in bird's serum, tissue, and increase return and net profit so; its addition and/or substitution will improve productive and economic efficiency.

Abstract: Background: Common bile duct (CBD) stone is the strong indication for surgical therapy, especially in patients with obstructive jaundice. With the development of laparoscopic equipment and technology, laparoscopic common bile duct exploration (LCBDE) has been widely used in clinical practice. Many previous studies have demonstrated that LCBDE is less invasive than conventional open surgery and it permits single-stage management of CBD stone. The aim of the study was to evaluate the safety and feasibility of laparoscopic common bile duct exploration (LCBDE) through cholangiotomy with T-tube placement in management of common bile duct stones (CBDS). Patients and methods: A total of 17 patients who were diagnosed with concomitant choledocholithiasis and cholelithiasis have undergone LCBDE using a choledochotomy (CBD) from December 2014 to janauary2017. The choledochoscope was inserted into the lumen of the CBD, all CBD stones were retrieved using a basket or a Fogarty balloon catheter or were irrigated with saline. After CBD clearance was confirmed using the choledochoscope, the choledochotomy was closed with the bard absorbable suture material Results: total of 17 patients (12males and 5 females) were recruited; the mean patient age in the present study was 47.88 ± 14.7 years. Preoperative liver function tests were obtained on the day before surgery. The bilirubin level ranged from 0.28 to 6.47 mg/dl (mean 3.13 ± 2.50 mg/dl), and gallstone pancreatitis was present in three patients which were treated preoperatively in a conservative manner with fluid resuscitation and nutritional support; surgery was performed when the symptoms were relieved and laboratory result return to normal. In terms of disease characteristics, the diameter of the CBD ranged from 8 to 27 mm (mean 12.2 ± 4.2 mm), and the number of CBD stones ranged from 1 to 4. The size of the largest CBD stone in each case ranged from 5 to 27 mm (mean 9.6 ± 7.4 mm). The mean operative time was 108.88 ± 30.3 min, and the mean length of the postoperative hospital stay was 6.0 ± 4.6 days. In patients who had large stones (over 10 mm, we used stone forceps to fragment and retrieve the stones. No patient developed symptoms or clinical signs that could be interpreted as late stricture. Four patients were converted to open surgery due to bleeding, severe inflammation, problems with equipment, or difficulties in introducing the T-tube. At follow-up, ALT, AST, ALP, and bilirubin returned to normal in all patients. Apart from that, no imaging or re-intervention was required for any of the patients. All patients recovered without any postoperative complications, except for 2 patients, one patient who developed postoperative pancreatitis and other patient develop biliary leakage and there were no recurrent stones. No death within 30 days after surgery was seen. Conclusions, LCBDE is a safe and feasible alternative for managing CBDS. The advantages are most pronounced in the case of multiple and large CBDS. The risk for retained stones and stricture is low.

Abstract: This research is tackling at win-case occurred between the tasks required by the staffs and the mission required by the organization. It highlights to what extent the nature of some organizations activity affects the conjunction state that’s found between the tasks that the employees are doing and the mission that the organizations is fulfilling. It practically takes universities as a field-study in order to show that the mission of universities is just a tautology of the distributed tasks done by the teaching, research, and community-serving staffs. The contributions done by the latter is actually representing the branched sub-components of the whole mission of the former. Accordingly this research is interested in showing, through a problem oriented method, that’s based upon hypothesizing, how the Egyptian universities compared with the foreign ones are currently having sort of deficiency in getting their missions done; as it ought to be. Due to the lack or deficiency in aligning the staff to work at the level they are personally looking forward to. Particularly when they are spontaneously put to strive for properly locating their universities at the required position, in terms of the missions’ fulfillment The main conclusion that’s gotten by statistically testing the hypotheses is hop revolved around considering the systems of education, research and community-serving are deficient in empowering staff to be aligned to their personal work-ambitions, which is an urgent condition for the universities’ proper fulfillment of the whole missions. Accordingly, it is far recommended by this research to consider such a co-occurrence case of people doing well tasks for organizations doing well missions.

Abstract: Objective: To correlate killip class with left ventricular dysfunction on echocardiography in patients with acute myocardial infarction. Study Design: Descriptive case series study. Sample technique: Non-probability consecutive. Materials and methods: 150 consecutive patients were included in this study. The present study was conducted on the newly diagnosed cases of acute myocardial infarction visiting emergency of cardiology department Liaquat University of Medical health science Hyderabad/Jamshoro, over a period of one year. Patients with prior history of acute myocardial infarction, valvular heart disease, cardiomyopathy, cardiac surgery, congenital heart disease, and patients with co-morbidities like renal failure, chronic liver disease, anemia, gastroenteritis, dehydration and chest diseases were not included in this study. Patients were classified as per killip’s classification and 2D echo was performed on patients within 24hours of admission. Findings of clinical examination (presenting killip class) were correlated with two-dimensional and Doppler echocardiographic findings. Results: Patients included in this study were grouped into four Killip classes separately in ST and Non ST elevation myocardial infarction. 107 (71.5%) cases were found with ST elevation MI, while NST elevation MI patients were found 43 (28.5%). In ST Elevation MI killip classes were found as: Class 1 (74.7%), Class II (14%), Class III (9%), and Class IV (8%). In Non ST elevation MI kilip classes were found as: Class I (79%), Class II (9.3%), Class III (6.9%) and Class IV (4.6%). Early mortality rate was greater in patients with both reduced ejection fraction EF 30% or < 30% and a higher Killip class. Patients with lower ejection fraction when they were in class1/11 compared with those in killip class 111/1V had increased morbidity and mortality. Mortality was more in STEMI 4.6% as compared with NSTEMI 1.1%, and in the STEMI cases mortality mostly found in class IV. Conclusion: Echocardiographic left ventricular ejection fraction obtained after an acute myocardial infarction is an affordable and readily available technique, which provides important prognostic information regarding patient’s clinical outcome along with prognosis. From our study, we conclude that Echocardiographic findings are correlated with Killip Class. Patients with higher Killip Class have lower ejection fraction, increased left ventricular size and complications.

Abstract: The total Antioxidant Capacity (TAC) of Sapium ellipticum (SE) leaf extract was evaluated using phosphomolybdenum and ABTS.+ Models. The results obtained showed that SE extracts possesses 561.18 mg Ascorbic acid equivalent Antioxidant Capacity (AETAC) and 0.62 nmoles Trolox equivalents Antioxidant Capacity (TEAC) per gram of the extract. SE extract expressed high level of superoxide dismutase (SOD) and catalase (CAT) activities and moderate glutathione peroxidase (GPx) activity. However, it was relatively low in both glutathione reductase (GR) and polyphenol oxidase (PPO) activities. Overall, the data of the present study suggest that SE is apparently a good source of SOD and CAT through its ability to respectively inhibit the photochemical reduction of nitro blue tetrazolium (NBT) chloride and promote the decomposition of H₂O₂ to oxygen and water in vitro [Ighodaro OM, Adeosun AM, Adeoye BA, and Soetan OG.
