Background: Hypothyroidism is a clinical syndrome prevalent in women, even those of reproductive age. Ovarian reserve can be defined as the number and quality of follicles in the ovary at any given time. Evaluation of ovarian reserve is recommended for patients at risk of decreased ovarian reserve. Objective: This study aims to evaluate the effect of hypothyroidism on ovarian reserve in Iraqi women by hormonal measurements of serum anti-mullerian hormones AMH, FSH, and LH. Subjects and methods: This case–control study was carried out at the Department of Biochemistry, College of Medicine, University of Baghdad, in collaboration with Endocrinology and Diabetes Clinic, Baghdad Teaching Hospital, and National Center for Teaching Laboratories, Medical City, during the period from November 2021 to March 2022. This study involved 88 women, age range (20-40 years). Fifty-one of them [Group I (GI)] had primary hypothyroidism and were diagnosed by an endocrinologist based on clinical analysis and thyroid function tests, including serum TSH, T4 and T3. Patients with symptoms and signs suggestive of hypothyroidism and elevated TSH with T4 less than the reference level were considered overt hypothyroidism. While patients with elevated TSH with standard T4 and T3 were considered subclinical hypothyroidism 1 , serum thyroid peroxidase antibody (TPOAb) was used to differentiate hypothyroidism patients with Hashimoto`s disease 2 . Thirty-seven of the included women were healthy and served as a control group and referred to group II (GII). Results: The mean (±SD) value of serum AMH of hypothyroidism women was significantly lower than that of controls (p < 0.0001). However, the mean value of AMH did not differ significantly between women who had overt and subclinical hypothyroidism, regular and irregular menstrual cycle, well and poorly controlled thyroid status, and who had positive and negative anti-TPO. The mean (±SD) value of serum LH of hypothyroidism women was significantly higher than that of the control group (p < 0.004), while that of FSH did not differ significantly. Serum TSH levels positively correlated with LH levels (r=0.3, p 0.03). In addition, BMI values were significantly positively correlated with FSH levels (r= 0.3, p 0.04). Conclusions: This study suggested the need for serum measurement of AMH in women suffering from hypothyroidism. Keywords: hypothyroidism, ovarian reserve, AMH.
This study investigates the changes occurring in the province of Basra using geospatial methods and analyzes the variations in land surface temperature among the various types of land cover. For the months of July and December in the years 2013 and 2021, Landsat images were used in Landsat 8 OLI/TIRS, and satellite images were processed using ArcGIS 10.8 software. The study's categories for land use and land cover were generated through the application of supervised classification techniques, and the land surface temperature was calculated using data from a satellite sensor's brightness temperature. According to the study's findings, there has been an increase in urban areas (including barren land). From 2013 to 2021, a greater correlati

Using a descriptive approach for analyzing and verifying the harmony of variables of research and their conceptualized logic , it could be reached to many conclusions agreed in their essence upon that the related diversification has the major role in value maximization of a firm and the wealth of its owners .
Conditional logistic regression is often used to study the relationship between event outcomes and specific prognostic factors in order to application of logistic regression and utilizing its predictive capabilities into environmental studies. This research seeks to demonstrate a novel approach of implementing conditional logistic regression in environmental research through inference methods predicated on longitudinal data. Thus, statistical analysis of longitudinal data requires methods that can properly take into account the interdependence within-subjects for the response measurements. If this correlation ignored then inferences such as statistical tests and confidence intervals can be invalid largely.
Globally, buildings use about 40% of energy. Many elements, such as the physical properties of the structure, the efficiency of the cooling and heating systems, the activity of the occupants, and the building’s sustainability, affect the energy consumption of a building. It is really difficult to predict how much energy a building will need. To improve the building’s sustainability and create sustainable energy sources to reduce carbon dioxide emissions from fossil fuel combustion, estimating the building's energy use is necessary. This paper explains the energy consumed in the lecture building of the Al-Khwarizmi College of Engineering, University of Baghdad (UOB), Baghdad, Iraq. The weather data and the building construction informati

Show MoreThe cathodic deposition of zinc from simulated chloride wastewater was used to characterize the mass transport properties of a flow-by fixed bed electrochemical reactor composed of vertical stack of stainless steel nets, operated in batch-recycle mode. The electrochemical reactor employed potential value in such a way that the zinc reduction occurred under mass transport control. This potential was determined by hydrodynamic voltammetry using a borate/chloride solution as supporting electrolyte on stainless steel rotating disc electrode. The results indicate that mass transfer coefficient (Km) increases with increasing of flow rate (Q) where .The electrochemical reactor proved to be efficient in removing zinc and was abl
