Background: Polycystic ovary syndrome (PCOS) is the most common endocrinopathy affecting women, at reproductive age. PCOS is a chronic hyperandrogenic state that has many significant short-term and long-term implications for patients such as oligomenorrhea, amenorrhea, infertility, diabetes mellitus, cardiovascular disease, increased risk of endometrial cancer, and hirsutism. Objectives: To evaluate the obesity and glycemic criteria among women with polycystic ovary syndrome. Method: A case control designed study was carried out at the National Diabetes Center (NDC) / Al-Mustansiryia University; on 50 participants formed the PCOS group and 50 healthy control participants. Data collected about age, age at menarche and BMI. Also, blood samples examined for FPG and 2-h OGTT test carried out for all the participants. Moreover hormonal assessment for the LH, FSH and total testosterone were done for all participants. Results : PCOS group women age and age at menarche were 27.62 ± 5.74 and 12.0 ± 1.06 years; vs. the control group were 25.42 ± 4.94 and 11.64 ± 0.69 years respectively. All PCOS group were experienced signs and symptoms of ovarian dysfunction, and infertility while the control group did not experience any of such evidences. BMI showed significant difference between study groups (t-test (P < 0.05)); 98% of the PCOS group was obese vs. 58% of the control group. The waist/hip ratio showed insignificant difference (t-test (P > 0.05). Fasting plasma glucose (FPG) showed insignificant difference between the study groups (t-test (P >0.05); about 18% of the PCOS group was prediabetic (Impaired Fasting Glucose, IFG) (100-125mg/dl) and 6% was diabetic (>126mg/dl) whereas the entire control group was normoglycemic. The OGTT showed significant difference between the study groups (ttest (P < 0.05)); about 22% of the PCOS group was prediabetic (Impaired Glucose Tolerance, IGT) (140- 199mg/dl) and 6% was diabetic (>200mg/dl) whereas the entire control group was normoglycemic. PCOS group showed highly significant elevation in the LH level vs. the control group by about four folds (t-test (P < 0.05)). Also, FSH showed similar elevation by about two folds among the PCOS group vs. the control group (t-test (P < 0.05)). Moreover the LH/FSH ratio was elevated by about two folds among the PCOS group vs. the control group (t-test (P < 0.05)). Total serum testosterone of the PCOS group showed significant raise vs. the control group (t-test (P < 0.05)). Whole the PCOS group had A total testosterone level >60 ng/dL and in contrary the entire control group didn't show any elevation >60ng/dl. Conclusion: obesity of android (central) type was frequent and prevalent among PCOS women. About 20-28% of PCOS women was prediabetic or diabetic due to insulin resistance and decreased insulin sensitivity. Hormonal assay of LH, FSH, LH/FSH ratio and total testosterone were all significantly elevated by two folds or more among the PCOS women. It is not essential that a woman who had polycystic ovaries by ultrasound to have PCOS
On the basis of known coumarin-based prodrug system, a novel coumarin-based mutual prodrug of 5-fluorouracil and dichloroacetic acid was designed, synthesized and evaluated as a promising oral chemotherapeutic agent basing on in vitro stability study in HCl buffer (pH 1.2) and in phosphate buffer (pH 7.4), as well as in vitro release study in human serum. The chemical structure of prodrug was confirmed by analyzing its FTIR, 1H NMR, 13C NMR and MS-ESI spectra. The results of in vitro kinetic study indicated that the prodrug was significantly stable in HCl and in phosphate buffers, and was hydrolyzed in human serum followed pseudo first order kinetics.

Two different approaches, univariate and multivariate (simplex method), have been used to obtain the optimum conditions for the quantitative Spectrophotometric determination of Eu3+ using Solochrome violet RS (3-Hydroxy-4-(2-hydroxy phenyl azo) naphthalene -1sulfonic acid) (SVRS) as a chromogenic reagent. The investigation shows that Eu3+ ion forms a wine-red complex with SVRS in alkaline buffer solution having a maximum absorbance at 464 nm against reagent blank. Calibration graphs obtained under univariate and simplex were found to be linear in the range of (0.30-8.0) µg/ml with detection limit 0.061µg/ml and molar absorptivity of 9877.66 L/mol.cm and (0.40-10.0)µg/ml with

It is assumed that the model considered the effect of harvesting and all the species are infected by some toxicants released by some other species. The stability analysis of all possible equilibrium points is discussed. The persistence conditions of the system are established. The occurrence of local bifurcation around the equilibrium points is investigated. Numerical simulation is used and the obtained solution curves are drawn to illustrate the results of the model. Finally, the nonexistence of periodic dynamics is discussed analytically as well as numerically.

Abstract
The aim of this paper is to model and optimize the fatigue life and hardness of medium carbon steel CK35 subjected to dynamic buckling. Different ranges of shot peening time (STP) and critical points of slenderness ratio which is between the long and intermediate columns, as input factors, were used to obtain their influences on the fatigue life and hardness, as main responses. Experimental measurements of shot peening time and buckling were taken and analyzed using (DESIGN EXPERT 8) experimental design software which was used for modeling and optimization purposes. Mathematical models of responses were obtained and analyzed by ANOVA variance to verify the adequacy of the models. The resul
