The present study aims to estimating the prevalence of autoimmune thyroid disorders in Iraqi infertile women with polycystic ovary syndrome (PCOS). Eighty-five Iraqi women, with age range (19-45) years, were divided into three groups; first group included 33 women with PCOS; second group included 30 women without PCOS; while third group included 22 fertile women as controls. The clinical data [age, body mass index (BMI), and menstrual status] have been recorded. Blood samples were collected to determine the levels of reproductive hormones [estradiol (E2), luteinizing hormone (LH), and follicle stimulating hormone (FSH)]; and thyroid hormones [triiodothyronine (T3) and thyroxin (T4)]. Also, autoimmune thyroid antibodies assessment has been carried out to determine the titrations of anti-thyroid peroxidase antibody (Anti-TPO Ab) and anti-thyroglobulin antibody (Anti-TG Ab).The findings revealed that thepercentage of obese was significantly (P<0.01) higher in the women with PCOS and without PCOS (66.67% and 53.34%, respectively) compared with the control women (9.10%). Also, more of the infertile women with PCOS and without PCOS (51.51% and 46.67%, respectively) had oligomenorrhea. The results of hormonal analyses revealed that non-significant (P>0.05) differences were found in levels of E2 and FSH among the different groups. A significant (P<0.05) increase was recorded in level of LH among PCOS group compared with control and without PCOS groups. Also, LH/FSH ratio was increased significantly (P<0.05) in PCOS group compared with control and without PCOS groups. On the other hand, the results of thyroid hormones showed non-significant (P>0.05) differences for T3 and T4 levels among the studied groups. Autoimmune thyroid antibodies assessment showed a significant (P<0.05) increased in the Anti TPO Ab titration among the infertile women with and without PCOS compared with the control; while there was a non-significant (P>0.05) difference between infertile women with PCOS and without PCOS. A significant (P<0.05) increased in the Anti TG Ab titration was found among infertile women with and without PCOS compared with the control group; also, a significant (P<0.05) increased was found in the infertile women without PCOS compared to with PCOS. Correlation between autoimmune thyroid antibodies and the studied hormones in women with and without PCOS revealed only a significant (P<0.01) positive correlation between Anti-TPO Ab titration and LH level (r=0.26); while a non-significant correlation has been found between Anti-TG Ab titration and the studied hormones.
Silver selenide telluride Semiconducting (Ag2Se0.8Te0.2) thin films were by thermal evaporation at RT with thickness350 nm at annealing temperatures (300, 348, 398, and 448) °K for 1 hour on glass substrates .using X-ray diffraction, the structural characteristics were calculated as a function of annealing temperatures with no preferential orientation along any plane. Atomic force microscopy (AFM) and X-ray techniques are used to analyze the Ag2SeTe thin films' physical makeup and properties. AFM techniques were used to analyze the surface morphology of the Ag2SeTe films, and the results showed that the values for average diameter, surface roughness, and grain size mutation increased with annealing temperature (116.36-171.02) nm The transm

The nymphs and adults prey on all the stages of various species of insects. Twelve adult specimens were collected from Erbil Province during May 2018 and June 2021. Morphological structures of the adult insects were described and illustrated in details; important taxonomic characteristics of body regions with their appendages were chosen; and the results indicated the importance of morphological characteristics which confirmed the identification of this species correctly.
The beet armyworm (BAW), Spodoptera exigua (Lepidoptera: Noctuidae) is a highly destructive pest of vegetables and field crops. Management of beet armyworm primarily relies on synthetic pesticides, which is threatening the beneficial community and environment. Most importantly, the BAW developed resistance to synthetic pesticides with making it difficult to manage. Therefore, alternative and environment-friendly pest management tactics are urgently required. The use of pesticidal plant extracts provides an effective way for a sustainable pest management program. To evaluate the use of pesticidal plant extracts against BAW, we selected six plant species (Lantana camara, Aloe vera, Azadirachta indica, Cymbopogon citratus, Nicotiana tabacum ,

The most significant water supply, which is the basis of agriculture, industry and human and wildlife needs, is the river. In order to determine its suitability for drinking purposes, this study aims to measure the Water Quality Index (WQI) of the Tigris River in the Salah Al-Din Province (center of Tikrit), north of Baghdad. For ten (9) physio-chemical parameters, namely turbidity, total suspended sediments, PH, electrical conductivity, total dissolved solids, alkalinity, chloride, nitrogen as nitrate, sulphate, and then transported for examination to the laboratory, water samples were collected from 13 locations along the Tigris river. Using the weighted arithmetic index method, the WQI was measured and found to be 105,87 in up-stream, wh

In this research , we study the inverse Gompertz distribution (IG) and estimate the survival function of the distribution , and the survival function was evaluated using three methods (the Maximum likelihood, least squares, and percentiles estimators) and choosing the best method estimation ,as it was found that the best method for estimating the survival function is the squares-least method because it has the lowest IMSE and for all sample sizes
