Mohamed N. El-Gharib, Manal A. Farahat, Mahmoud Daoud
Open Journal of Obstetrics and Gynecology (OJOG) , 2013, DOI: 10.4236/ojog.2013.32045
Abstract:

Aim: To assess the role of Magnetic resonance imaging (MRI) and pelvic organ prolapse quantification (POPQ) system in the evaluation of female pelvic organ prolapse. Design: Prospective study. Setting: TantaUniversityHospital. Patients: The study was carried out on 60 patients having clinical manifestations suggesting pelvic floor weakness. Intervention: All the patients were subjected to history taking, physical examination including POPQ, and pelvic MRI (static and dynamic) examination. Outcome measures: Quantitative measurements of genital prolapse. Results: All patients showed loss of the normal position of the perineal plate indicating generalized weakness of the whole pelvic floor muscles. Dynamic MRI exhibited pelvic floor abnormalities in 46 patients who did not show any abnormalities on the static images. Conclusion: Dynamic MRI is a helpful tool in defining the nature and quantitative measurements of pelvic organ prolapse. Also, MRI has and advantage over POPQ system in diagnosing lateral prolapse.

Open Journal of Obstetrics and Gynecology (OJOG) , 2014, DOI: 10.4236/ojog.2014.46042
Abstract:

Objective: To compare maternal and fetal outcome associated with two methods Reverse breech extraction versus Head pushing to deliver the impacted fetal head in advanced labor requiring emergency Cesarean section. Method: A prospective comparative study was conducted on 80 pregnant women at term with cephalic presentation in advanced labour, requiring emergency Cesarean Section. Reverse breech extraction technique (pull method) was used in 40 cases (group I) and pushing the head up through the vagina (“push” method) was tried in (group II) 40 cases. The maternal outcome was assessed by extension of the uterine Incision, bladder injury, intra and postoperative blood transfusion, Postpartum hemorrhage, wound infection and duration of hospital stay. Fetal outcome was Apgar score and admission to neonatal intensive care unit. Results: Extension of the uterine incision was significantly lower in women undergoing reverse breech extraction compared to cephalic delivery (20% versus 50%; p = 0.001). The mean operative time (pull group) was lower than that in the (push group) 59.7 ± 4.2, versus 75.2 ± 6.1 p = 0.001 and blood loss was significantly lower in the (pull group) than that in the (push group) 878 ± 67 ml, versus 1321 ± 57 ml, p = 0.001. No significant difference between groups regarding maternal and neonatal outcome. Conclusion: Reverse breech extraction

Entanglement Quantifier Based on Atomic Wehrl Entropy for Non-Linear Interaction between a Single Two-Level Atom and SU(1,1) Quantum System  [PDF]
Sayed Abdel-Khalek, Manal Al-Quthami, Mohamed M. A. Ahmed
Journal of Quantum Information Science (JQIS) , 2014, DOI: 10.4236/jqis.2014.41004
Abstract:

In this paper, we study the dynamics of the atomic inversion, scaled atomic Wehrl entropy and marginal atomic Wehrl density for a single two-level atom interacting with SU(1,1) quantum system. We obtain the expectation values of the atomic variables using specific initial conditions. We examine the effects of different parameters on the scaled atomic Wehrl entropy and marginal atomic Wehrl density. We observe an interesting monotonic relation between the different physical quantities for different values of the initial atomic position and detuning parameter.

Open Journal of Veterinary Medicine (OJVM) , 2015, DOI: 10.4236/ojvm.2015.59027
Abstract: Detrimental effects of heat stress that causes great loss to poultry industry have grown the global attention for the importance of natural antioxidant in alleviating the oxidative stress symptoms in poultry. The antioxidant effect of Chinese ether extract propolis (EEP) on broilers (Ross 308) exposed to chronic heat stress has been evaluated. Eighty broilers (15 days old) were randomly allocated into five equal groups; each received a maintenance diet supplemented by vitamin C (250 mg/kg diet) or propolis (250, 500 and 750 mg/kg diet) or not supplemented (control) for 27 consecutive days. Blood samples were collected to analyze serum corticosteron, total antioxidant capacity (TAC) and lipid peroxidation activity (MDA) at the end of the experiment. Moreover, the active chemical components responsible for the biological activities of EEP have been determined using Gas Chromatography/Mass Spectrometry (GC/MS). Results revealed a significant decrease in corticosterone levels in broilers after vit C or EEP supplementation. This improvement is parallel to a significant increase in TAC and decrease in MDA in broilers after EEP supplementation, which may be due to its high flavonoid content. Results show that Chinese EEP has biologically active compounds responsible for excellent antioxidant activities that ameliorate the negative impacts of elevated temperature in summer season in Egypt.

Research Opinions in Animal & Veterinary Sciences , 2011,
Abstract: Twenty Holstein dairy cows in second to fifth lactations were used to examine the effect of guar germ at different levels on yield and quality of milk. Animals were divided randomly into four groups (A, B, C and D) of almost similar weight and milk production. The animals of group A, B, C and D were fed on 0, 50, 75 and 100% of guar germ. All diets were iso-caloric and iso-nitrogenous. The duration of experiment was 8 weeks and 2 weeks for adaptation period. The results indicated that there were significant differences (P<0.05) in milk yield (between) group B and D and total solid of milk (between group A,C, D and group B) whereas the milk yield was highest in group D, total solid of milk was highest in groups A, C and D. However no significant differences (P>0.05) were found between treatments in the percentage of milk fat. The study of sensory evaluation of milk showed no significant differences (P<0.05) between the four treatments in colour, flavour and taste for fresh and boiled milk. On the basis of results obtained from this study, guar germ can be used in diets of dairy cows to replace groundnut cake without any negative effects on the quantity and quality of milk.

Study of Selenium Concentration in Patients with Newly Diagnosed Non-Hodgkin`s Lymphoma
Maha I. Esmaeel,Mohamed A. Ebrahim,Manal A. Salah-Eldin,Mohamed I. Esmaeel
Journal of Medical Sciences , 2008,
Abstract: This study was designed to examine selenium concentrations in patients with newly diagnosed Non-Hodgkin`s Lymphoma (NHL) and the possible association between the levels of this trace element with clinical features of the disease. Also, to test the hypothesis that selenium concentration at presentation would predict for response to treatment. This study was carried out on fifty-patients with newly diagnosed NHL and 25 control subjects, blood samples were taken for measurement of selenium by spectrometry. In comparison to the control subjects the serum selenium level was significantly lower with NHL with a mean of 0.033 (SD, 0.1) vs 0.81 (SD, 0.05), p<0.001. The mean serum selenium was significantly lower in patients with poorer performance status (p = 0.03) and in patients with advanced stage (p = 0.02), but there was no significant relation to the aggressiveness of the disease. Serum albumin was the only parameter that showed a significant positive correlation with serum selenium. There was a trend for serum selenium level to be higher in patients who achieved CR, but the difference was not statistically significant (p = 0.1). Selenium may play a role in the pathogenesis and prognosis of patients with NHL. In this study; the level of selenium was found inversely associated with the clinical stage of the disease and the performance status and may predict for the response to treatment in aggressive lymphoma. The possible utility of measuring serum selenium in NHL deserves further evaluation in clinical trials.

Open Journal of Marine Science (OJMS) , 2017, DOI: 10.4236/ojms.2017.72023
Abstract: The residual concentrations of HCHs, TC, DDTs, THCs and PCBs were measured in Sparus auratus collected from the eastern and western sectors of the Egyptian Mediterranean Sea, as the most common fish species in the area. Gas chromatograph equipped with 63Ni-electron capture detector and 35% phenyl polysilphenylenesiloxane capillary column was used for the analysis and quantification after well-established extraction techniques. The concentrations (wet weight) of PCBs, DDTs, TCs, HCHs were: (1.87 - 616.66 ng·g-1), (0.42 - 98.28 ng·g-1), (0.06 - 2.94 ng·g-1), (0.35 - 11.77 ng·g-1), respectively in Sparus auratus collected from the eastern sector. However, these concentrations as wet weight in Sparus auratus from the western sector were: (5.75 - 605.53 ng·g-1), (1.53 - 226.47 ng·g-1), (0.09 - 8.12 ng·g-1), (0.26 - 5.80 ng·g-1), respectively. In general, concentrations of pesticides and PCBs in Sparus auratus either from the western or eastern Egyptian Mediterranean coast were far below the international permissible levels.

Wafaa S. Ahmed,Mona A. Mohamed,Rabab A. El-Dib,Manal M. Hamed
Molecules , 2009, DOI: 10.3390/molecules14051952
Abstract: From the leaves of Duranta repens (Verbenaceae) two new triterpene saponins, named durantanin IV (1) and V (2)were isolated.In addition, ten known compounds were isolated, namely a bidesmosidic saponin, oleanolic acid, three phenylethanoids and five flavonoids. All metabolites were isolated for the first time from this genus except for 3 (oleanolic acid) and 7 (E/Z acteoside). The structures were determined mainly by spectroscopic methods (UV, IR, HRESI-MS, 1H-, 13C-NMR, 1H-1H COSY, HSQC and HMBC). Cytotoxic screening of the chloroform, ethyl acetate and methanol extracts was carried out on brine shrimps. In addition, the investigated methanol extract and compounds 1, 2 and 7 showed significant cytotoxic activity against a HepG2 cell line.
