Open Journal of Obstetrics and Gynecology (OJOG) , 2019, DOI: 10.4236/ojog.2019.93036
Abstract: Background: As regard to adjuvant supplementations, nowadays dehydroepiandrosterone (DHEA) is widely used all over the world and is considered to be a potential agent to ameliorate the assisted reproduction technologies outcomes of infertile women with poor ovarian reserve. Objective: To find out the role of DHEA supplementation in improving intracytoplasmic sperm injection (ICSI) outcome for infertile women with expected poor ovarian response in controlled ovarian stimulation. Setting: Assisted reproduction unit of Obstetrics and Gynecology Department, Faculty of Medicine, South Valley University, Egypt. Duration: From April 2016 to May 2018. Study Design: A randomized double-blinded controlled trial. Methods: One hundred and forty infertile women with expected poor ovarian response prepared for ICSI procedure were included in this study. Patients were divided into two groups; group I (DHEA group) included 70 patients received 25 mg DHEA 12 weeks prior to ICSI cycle and group II (placebo group) included 70 patients received a placebo. Results: There was a highly statistically significant difference in basal AFC at start of ICSI cycle in group I (who received DHEA supplementation for 12 weeks prior to ICSI procedure) than in group II (13.8 ± 5.3 versus 10.7 ± 4.6 respectively) with P < 0.001. There were mildly statistically significant differences between group I and group II as regard to increase in the number and quality of retrieved oocytes, increased in endometrial thickness, fertilization rate and embryo quality with p value < 0.05 but there was no statistically significant difference between the 2 groups as regard to pregnancy (chemical and clinical) rates (p value > 0.05).

BMC Anesthesiology , 2010, DOI: 10.1186/1471-2253-10-7
Abstract: Three hundred sixty patients with symptomatic BPH were randomized into a prospective, controlled trial comparing the three irrigation modalities. One-hundred twenty patients used glycine 1.5% solution as irrigating fluid (glycine group), 120 patients used glucose 5% solution (glucose group) and 120 patients used normal saline 0.9% solution (saline group). Patient's demographics, operation time, hospital stay, postoperative amino acid glycine assay, postoperative serum cardiac troponin I and perioperative complications were noted.No difference was found between the groups in the immediate postoperative levels of hemoglobin and hematocrite. A high glycine level was associated with the TUR syndrome. Seventeen patients had TUR syndrome; all were in glycine group and they had the highest postoperative amino acid glycine levels. Slight increase in serum sodium (142.6 ± 12.6 mmol/l) was detected in saline group. Transient Hyperglycemia (170 ± 35.9 mg/dl) and hypokalemia (3.67 ± 0.92 mmol/l) occurred in the immediate postoperative period in the glucose group.Endoscopic TURP performed using either glucose 5% or saline 0.9% irrigating solution during and after surgery is associated with lower incidence of TUR syndrome, lower catheterization period, shorter hospital stay and no cardiac toxicity in comparison with glycine 1.5% solution.This clinical trail had been approved and registered in PACT Registry; with identification number for the registry is ATMR2010010001793131.Many endoscopic surgical procedures require the use of an irrigating fluid to dilate the operating field and to wash away debris and blood. A potential complication of such irrigation is a systemic absorption of the fluid to the extent that overt symptoms are produced [1]. The ideal irrigant for endoscopic resection would be a user-friendly, non-conductor medium that does not interfere with diathermia, has a high degree of translucency, has similar osmolarity to the serum and causes only minimal side effects w

Computer Science , 2009,
Abstract: In the present paper, high transmission bit rate of a thermal arrayed waveguide grating (AWG) which is composed of lithium niobate (LiNbO3)/polymethyl metha acrylate (PMMA) hybrid materials on a silicon substrate in Passive Optical Networks (PONs) has parametrically analyzed and investigated over wide range of the affecting parameters. We have theoretically investigated the temperature dependent wavelength shift of the arrayed waveguide grating (AWG) depends on the refractive-indices of the materials and the size of the waveguide. A thermalization of the AWG can be realized by selecting proper values of the material and structural parameters of the device. Moreover, we have analyzed the data transmission bit rate of a thermal AWG in passsive optical networks (PONs) based on Maximum Time Division Multiplexing (MTDM) technique.

El Kholy Amani Ali,1 Gomaa Howayda Ezzeldin,2 El Anany Mervat Gaber,1 Abd El Rasheed Enas2
Journal of Infection in Developing Countries , 2007,
Abstract: Background: Brucellosis is a significant health problem in Egypt.Methodology: To establish a PCR technique for diagnosis of active brucellosis in our institutions, DNA extraction was done using a commercial kit, and a laboratory extraction procedure. PCR amplification was done using 2 sets of primers: B4/B5 and JPF/JPR. Extraction of Brucella DNA using the commercial kit failed; therefore, this technique was discontinued. The laboratory extraction method was successful and more economic.Results: The technique showed high sensitivity, specificity, and accuracy. The PCR positivity increased significantly (P=0.001) with increasing the positive standard tube agglutination titer and showed 100% positivity in patients with positive blood culture.Conclusions: An accurate and sensitive PCR technique was established. Based on the results, the PCR method is recommended as an alternative to culture for the diagnosis of brucellosis. A large-scale study to evaluate this PCR technique to screen for brucellosis in Egypt is needed.
Waterlogging in the New Reclaimed Areas Northeast El Fayoum, Western Desert, Egypt, Reasons and Solutions  [PDF]

Journal of Water Resource and Protection (JWARP) , 2014, DOI: 10.4236/jwarp.2014.618147
Abstract: The waterlogging in the new reclaimed areas has become a major concern in the area Northeast El Fayoum, Western Desert, Egypt. It is not only endangering the structures and properties but also causing major environmental problem affecting the health of the area, habitats, and the biotic of the land community, as well as the deteriorating of Egypt’s Pharaonic monuments (El Lahun and Hawarah pyramids). Both the daily seepage from excess irrigation water and the presence of impervious clay or limestone beds at shallow depths may represent the main contributor of ground-water rising in the shallow aquifer. This paper investigates the interplay of the hydrogeological characteristics, soil properties and recent land reclamation projects on the distribution of waterlogging and salinization within the study area. The field observations show that new reclaimed areas have been recently cultivated in distant areas from the old agricultural land. These new cultivations have developed widespread waterlogging, soil salinization and deterioration of Egypt’s Pharaonic monuments as a result of rising groundwater related problems. In this paper, the data used come from database of drillings for eleven observation wells distributed inside the whole area to measure periodic water levels. The soil litho-units are mainly composed of coarse sand, sandy clay, silt and fractured limestone underlined by impervious clay or limestone, thus limiting the downward percolation of excess irrigation water and therefore develops waterlogging. The drainage networks and suitable irrigation methods have to be considered when planning for a new cultivation in dry land to better control waterlogging and salinization hazard. It is highly recommended in this research that newly small and deep cut drainage canals network should be constructed and connected to the master drainage canal to dewater the excess irrigation water and to prevent the waterlogging in the concerned area.

Ciência & Tecnologia dos Materiais , 2008,
Abstract: the corrosion inhibition of zinc in 0.1m hcl in presence and absence of some hydrazide derivatives has been investigated using mass-loss and polarization techniques. results obtained showed that the inhibition efficiency increased with the increase of the concentration of the additives and decreased with the increase of temperature. synergism between i- , scn- and br- anions and hydrazide derivatives was proposed. the polarization curves showed that hydrazide derivatives act as mixed-type inhibitors, acting predominantly as cathodic inhibitors for zinc in 0.1m hcl .the adsorption of these hydrazide derivatives on zinc surface follows temkin?s adsorption isotherm. some thermodynamic parameters were calculated. the kinetic parameters of corrosion of zinc in hcl solution have been studied.
