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
In this work the fabrication and characterization of poly(3-hexylthiophene) P3HT-metallic nanoparticles (Ag, Al). Pulsed Laser Ablation (PLA) technique was used to synthesis the nanoparticles in liquid. The Fourier Transformer Infrared (FTIR) for all samples indicate the chemical interaction between the polymer and the nanoparticles. Scanning Electron Microscopic (SEM) analysis showed the particle size for P3HT-AgNps samples between 44.50 nanometers as well the spherical structure. While for P3HT-AlNps samples was flakes shape. Energy Dispersive X-ray (EDX) spectra show the existing of amount of metallic nanoparticles.
Animal fats are a good, promising and ethical alternative source for biodiesel production, but they need more complex treatments than vegetable oils. Iraqi butchery plants waste fats (sheep fat) which are suggested as feedstock to produce biodiesel. This type of fat contains a large quantity of free fatty acids (FFAs) (acid number 49.13 mg KOH/g of fat). The direct transesterification of such fats produce high amount of soap instead of desired biodiesel, so a pre-treatment step (to reduce FFAs) is necessary before transesterification. This step was done by esterification of the free fatty acids in the fat by adding ethanol and using 1% acid catalyst (H2SO4) for 30 minutes. The results showed that the acid number of sheep fat after pre-tr

Show MoreThe aim of this paper is to explore the relationship between sustainability reporting (SR) and corporate reputation (CR) in the context of initial public offering (IPO) companies in the developing market of Malaysia. This study utilises secondary data from 2007 to 2017 derived from the content analysis of the annual reports and Datastream of 139 sampled IPO companies listed on Bursa Malaysia. The study also employs ordinary least squares (OLS) regression. The result shows that CR has a positive association with SR quantity and quality and its dimensions, i.e., society, environmental, employee, and product. This result suggests that IPO companies can use SR practices to improve their CR. Most companies give little attention to SR issues. Mor

In this work, the design and implementation of a smart energy metering system has been developed. This system consists of two parts: billing center and a set of distributed smart energy meters. The function of smart energy meter is measuring and calculating the cost of consumed energy according to a multi-tariff scheme. This can be effectively solving the problem of stressing the electrical grid and rising consumer awareness. Moreover, smart energy meter decreases technical losses by improving power factor. The function of the billing center is to issue a consumer bill and contributes in locating the irregularities on the electrical grid (non-technical losses). Moreover, it sends the switch off command in case of the consumer bill is not

Gold nanoparticles AuNPs have proven to be powerful tools in various nanomedicine applications, because of their photo-optical distinctiveness and biocompatibility. Noble metal gold nanoparticles was prepared by pulsed laser ablation method (1064-Nd: YAG with various Laser power from 200 to 800 mJ and 1 Hz frequency) in distil water.
