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.
This study was aimed to investigate the effect of sperm parameters on the response to in vitro sperm activation (ISA) and to compare sperm parameters according to the age and type of infertility.
One hundred twenty-eight subjects employed in this study, with age range (18-49) years and duration of infertility (1-28) years. From each subjects semen sample was obtained and seminal fluid analysis (SFA) was done. Simple medium for assisted reproductive techniques; (SMART) was used for in vitro sperm activation by direct swim-up technique and centrifugation Swim-Up technique. Sperm concentration, sperm motility (%), sperm grade activity (%), normal sperm morphology (%) and sperm agglutination (%) were assessed. Crude data were statisticall

Show MoreBased on previous research results that recognized the role of paternalistic leadership in promoting a positive work climate, this study explored the impact of a toxic work environment on the mental health and well-being of employees. We used the quantitative methodology to collect and analyze data. A sample of 108 participants from Iraqi internet service provider (ISPs) companies represented the purposive study sample. We targeted employees who experienced the COVID-19 pandemic. All data was collected through an electronic questionnaire (Google and Microsoft Forms). The research model was tested using structural equation modeling (SEM). The results showed a negative effect of the toxic workplace on the mental health of employees. T

The research aims to apply the novel forward osmosis (FO) process to recover pure water
from contaminated water. Phenol was used as organic substance in the feed solution, while sodium
chloride salt was used as draw solution. Membranes used in the FO process is the cellulose
triacetate (CTA) and polyamide (thin film composite (TFC)) membrane. Reverse osmosis process
was used to treatment the draw solution, the exterior from the forward osmosis process. In the FO
process the active layer of the membrane faces the feed solution and the porous support layer faces
the draw solution and this will show the effect of dilutive internal concentration polarization and
concentrative external concentration polarization.

This paper presents a brief study undertaken for improving the performance of information and communication management of construction projects through investing in information and communication technologies (ICT). The work aims at first to investigate and diagnose the problems, challenges, weaknesses, and inefficiencies related to information and communication management in projects in the construction industry of Iraq. Studying the diagnosed matters and the different solutions of ICT to improve project management performance is following the investigation process. The research presents a technological system suggested to process a lot of the diagnosed problems, challenges, weakness, and inefficiencies of the construction projects and t
