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
The azo dye brilliant reactive red K-2BP (λmax = 534 nm) is widely used for coloring textiles because of its low-cost and tolerance fastness properties. Wastewaters treatment that contains the dye by conventional ways is usually inadequate due to its resistance to biological and chemical degradation. During this study, the continuous reactor of an advanced oxidation method supported the use of H2O2/sunlight, H2O2/UV, H2O2/TiO2/sunlight, and H2O2/TiO2/UV for decolorization of brilliant reactive red dye from the effluent. The existence of an optimum pH, H2O2 concentration, TiO2 concentration, and d

Proteus mirabilis is considered as a third common cause of catheter-associated urinary tract infection, with urease production, the potency of catheter blockage due to the formation of biofilm formation is significantly enhanced. Biofilms are major virulence factors expressed by pathogenic bacteria to resist antibiotics; in this concern the need for providing new alternatives for antibiotics is getting urgent need, This study aimed to explore whether green synthesized zinc oxide nanoparticles (ZnO NPs) can function as an anti-biofilm agent produced by P.mirabilis. Bacterial cells were capable of catalyzing the biosynthesis process by producing reductive enzymes. The nanoparticles were synthesized from cell free

Sewer system plays an indispensable task in urban cities by protecting public health and the environment. The operation, maintenance, and rehabilitation of this network have to be in a sustainable and scientific manner. For this purpose, it is important to support operators, decision makers and municipalities with performance evaluation procedure that is based on operational factors. In this paper, serviceability and performance indicator (PI) principles are employed to propose methodology comprising two enhanced PI curves that can be used to evaluate the individual sewers depending on operational factors such as flowing velocity and wastewater level in the sewers. In order to test this methodology; a case study of al-Ru

In this paper, a mathematical model for the oxidative desulfurization of kerosene had been developed. The mathematical model and simulation process is a very important process due to it provides a better understanding of a real process. The mathematical model in this study was based on experimental results which were taken from literature to calculate the optimal kinetic parameters where simulation and optimization were conducted using gPROMS software. The optimal kinetic parameters were Activation energy 18.63958 kJ/mol, Pre-exponential factor 2201.34 (wt)-0.76636. min-1 and the reaction order 1.76636. These optimal kinetic parameters were used to find the optimal reaction conditions which

Dental clinicians and professionals need an affordable, nontoxic, and effective disinfectant against infectious microorganisms when dealing with the contaminated dental impressions. This study evaluated the efficiency of hypochlorous acid (HOCl) as an antimicrobial disinfectant by spraying technique for the alginate impression materials, compared with sodium hypochlorite, and its effect on dimensional stability and reproduction of details. HOCl with a concentration of 200 ppm for 5 and 10 min was compared with the control group (no treatment) as a negative control and with sodium hypochlorite (% 0.5) as a positive control. Candida albicans, Staphylococcus aureus, and Pseudomonas aeruginosa were selected to assess the antimicrobi

objective: To evaluate the influence of monolithic zirconia brand, thickness, and substrate color on color matching accuracy when optically coupled to abutment substrates. Methods: A total of 180 samples of two brands of monolithic zirconia [Prettau Anterior (PA), Ceramill Zolid FX Multicolor (CZ)] were prepared in three different thicknesses (0.8 mm, 1.5 mm, and 2 mm) with a standardized 10 mm diameter. Color properties of the samples were assessed using spectrophotometry at baseline and after coupling to three substrate types: standard dentin, discolored dentin, and titanium. Color differences (ΔE) were calculated and statistically analyzed by 3-way ANOVA and pairwise comparison ( α=0.05). Results: The brand and material thickness, at

This article examines and proposes a dietary chain model with a prey shelter and alternative food sources. It is anticipated that mid-predators' availability is positively correlated with the number of refuges. The solution's existence and exclusivity are examined. It is established that the solution is bounded. It is explored whether all potential equilibrium points exist and are locally stable. The Lyapunov approach is used to investigate the equilibrium points' worldwide stability. Utilizing a Sotomayor theorem application, local bifurcation is studied. Numerical simulation is used to better comprehend the dynamics of the model and define the control set of parameters.
