Endometriosis, an autoimmune disease is among one of the most challenging of the 21 st century that affects women in reproductive age. The aim of the present study is to highlight the role of IL-36γ, and its relationship with other cytokines (Ang-2 and TNF-α) in the pathogenesis of endometriosis . Seventy five (75) consecutive women patient of reproductive age (25-40) years were enrolled in this study , Patients were divided into three groups , group 1 (G1) included (25) newly diagnosed endometriotic patients , that were not given any treatment related to Gynecology or anti-inflammatory medications . Second group : group 2 (G2) consists of (25) endometriotic patient who were treated with zoladex for 3 to 5 months , they received zoladex injection every 28 day in the first day after diagnosis. The third group: Group 3 (G3) involved (25) patients with recurrent endometriosis , they were post treatment of zoladex and diagnosis revealed recurrence of endometriosis. Patients groups were compared with two control groups , with matched age with patients’ groups. The first control group (C) included (25) healthy women , and the second control group or pathological control group (PC) involved (25) women suffering from infertility caused by gynecological disorder unrelated to endometriosis.IL-36γ , Ang-2 and TNF-α were estimated in sera of studied groups. The results from this study revealed that IL-36γ levels were highly significant increase (p<0.001) and significant increase (p<0.05) in G1 comparing with groups C and PC respectively. While high significant decrease(p<0.001) was found in G2 comparing with G1. Also , there are no significant differences (p≥0.05) shown in G2 comparing with C group and in G3 comparing with G1.On the otherhand , Ang-2 levels were highly significant increased (p<0.001) and significant increase (p<0.05) in G1 comparing with groups C and PC respectively. While significant decrease (p<0.05) was found in G2 comparing with G1. Also , there are no significant differences (p≥0.05) in Ang-2 levels shown in G2 comparing with C group and in G3 comparing with G1 Our results also implied that TNF-α levels were highly significant increased (p<0.001) in G1 comparing with C group. While no significant differences (p≥0.05) was found in G1 comparing with PC group and in G3 comparing with G1. Also there are significant differences (p<0.05) shown in G2 comparing with G1 and C group. Our findings for endometriotic patient groups. A high significant difference was found between Ang-2 and TNF-α levels with IL-36γ for G1 , G2 and G3. The conclusion of this study reveals that IL-36γ could be considered a novel biochemical marker in endometriotic patients. Conclusion could be drawn from the results that endometriosis may be influenced on the cytokines secretion such as IL-36γ beside Ang-2 and TNF-α in G1 and G3 , suggesting that inflammatory / immunological factors associating with angiogenesis responses play crucial roles in the pathogenesis of endometriosis. Also, the results showed the role of zoladex in alteration immune responses as shown in G2
ABSTRACT Porous silicon has been produced in this work by photochemical etching process (PC). The irradiation has been achieved using ordinary light source (150250 W) power and (875 nm) wavelength. The influence of various irradiation times and HF concentration on porosity of PSi material was investigated by depending on gravimetric measurements. The I-V and C-V characteristics for CdS/PSi structure have been investigated in this work too.

... Show MoreA sensitive spectrofluorimetric method for the determination of glibenclamide in its tablet formulations has been proposed. The method is based on the dissolving of glibenclamide in absolute ethanol and measuring the native fluorescence at 354 nm after excitation at 302 nm. Beers law is obeyed in the concentration of 1.4 to 10 µg.ml-1 of glibenclamide with a limit of detection (LD) of 0.067 µg.ml-1 and a standard deviation of 0.614. The range percent recoveries (N=3) is 94 - 103.
A UV-Vis spectrophotometry method was developed for the determination of metoclopramide hydrochloride in pure and several pharmaceutical preparations, such as Permosan tablets, Meclodin syrups, and Plasil ampoules. The method is based on the diazotization reaction of metoclopramide hydrochloride with sodium nitrate and hydrochloric acid to yield the diazonium salt, which is then reacted with 3,5-dimethyl phenol in the presence of sodium hydroxide to form a yellow azo dye. Calibration curves were linear in the range from 0.3 to 6.5 µg/mL, with a correlation coefficient of 0.9993. The limits of detection and quantification were determined and found to be 0.18 and 0.61 µg/mL, respectively. Accuracy and precision were also determined b

A reliable differential pulse polarographic (DPP) method has been developed and applied for the determination of ibuprofen IBU in dosage form with dropping mercury electrode (DME) versus Ag/AgCl. The best peak was found at cathodic peak of -1.18 V in phosphate buffer at pH=4 and 0.025M of KNO3 as supporting electrolyte. In order to obtaine the highest sensitivity, instrumental and experimental parameters were examined including the type and concentration of supporting electrolyte, pH of buffer solution, pulse amplitude and voltage step time. Diffusion current showed a direct linear relationship to ibuprofen concentration in the range of (5 – 30) μg. mL-1 (2.43× 10-5

A simple, rapid and sensitive spectrophotometric method has been developed for the determination of captopril in aqueous solution. The method is based on reaction of captopril with 2,3-dichloro 1,4- naphthoquinon(Dichlone) in neutral medium to form a stable yellow colored product which shows maximum absorption at 347 nm with molar absorptivity of 5.6 ×103 L.mole-1. cm-1. The proposed method is applied successfully for determination of captopril in commercial pharmaceutical tablets.
This work was conducted to determine the volumetric mass transfer coefficient (Ky.a) infixed bed adsorption using hexane-benzene mixture by adsorption onto a fixed bed of white silica gel. Benzene concentration was measured by gas chromatography. The effect of feed flow rate and initial concentration of benzene in hexane-benzene mixture on the volumetric mass transfer coefficient and on the adsorption capacity of silica gel was investigated.
In general, the volumetric mass transfer coefficient increases with increasing hexane flow rate, and with increasing initial concentration of benzene in the mixture. The ultimate value of (Ky.a) was at 53 ml/min of hexane flow rate with benzene initial concentration of (6.53 wt. %), and it wa

The research focuses on determination of best location of high elevated tank using the required head of pump as a measure for this purpose. Five types of network were used to find the effect of the variation in the discharge and the node elevation on the best location. The most weakness point was determined for each network. Preliminary tank locations were chosen for test along the primary pipe with same interval distance. For each location, the water elevation in tank and pump head was calculated at each hour depending on the pump head that required to achieve the minimum pressure at the most weakness point. Then, the sum of pump heads through the day was determined. The results proved that there is a most economical lo
