Background: Polycystic ovary syndrome (PCOS) is one of the common female endocrine disorders of uncertain etiology, which causes menstrual disorders as well as infertility. Interleukin–33(IL-33) is considered as a strong risk marker of inflammation and may have possible role in pathogenesis of PCOS.
Objectives: The present study is designed to investigate the possible role of IL-33 in pathogenesis of PCOS and its relation with glycated hemoglobin (HbA1C),insulin resistance(IR) and oxidative stress in prediabetic PCOS patients.
Subjects and Methods: The study involved 30 healthy women as control group and sixty six infertile Iraqi women with PCOS which were divided into two groups according to glycated heamoglobin(HbA1c) value and homeostasis model assessment for insulin resistance (HOMA-IR). The first group (G1) consist of 30 women with HbA1c ≤ 6.5% and HOMA –IR<3.8 as PCOS without diabetes and without insulin resistance. The second group(G2) consist of 36 patients with HbA1c ≥ 6.5 % and HOMA-IR ≥ 3.8 as PCOS with pre diabetes type 2 and insulin resistance. Ten milliliters of blood were collected from all subjects by vein puncture during 2nd – 4th day of the menstrual cycle. Two ml of blood were collected in EDTA tube for HbA1c analysis. The serum which obtained from the remained blood were used for determination of (insulin, fasting blood glucose(FBG), Malondialdehyde(MDA) , Total antioxidant capacity(TAC) , uric acid, glutathione(GSH), albumin, and IL-33) .
Results: Results revealed a significant elevation in HbA1c, insulin, HOMA-IR, MDA, TAC, uric acid and IL-33 in the patients group when compared with healthy women. On the other hand, a significant decreased in GSH and albumin were found in patients group when compared with control group. Also there are significant differences in the results between patients in group 1 and group 2. A significant positive correlation between IL-33 and HbA1c levels was noticed in G1 and G2 .A significant positive correlation between IL-33 and HOMA-IR was noticed in group 1 while a negative significant correlation was found in group 2. No correlation founded between IL-33 levels and TAC concentration in group 1, but a positive correlation noticed with group 2. A significant negative correlation was observed between IL-33 and MDA/TAS ratio in G1, while a significant positive correlation in G2 was found.
Conclusion: high levels of IL-33 in patient groups may be considered as a novel cytokine involved in the pathogenesis of PCOS. Also the elevation in oxidative stress in PCOS patients could be a reason for disturbed follicular development and ultimately infertility.
The study area is encompassed by the 33.59-34.93°N latitudes and 45.44-46.39°E longitudes and divided into four groups with respect to earthquake event locations. We determined fault plane solutions, moment magnitudes, focal depths, and trend of slip with the direction of the moment stress axes (P, N, and T) for 102 earthquakes. These earthquakes had a local magnitude in the range between 4.0 and 6.4 for the time period from January 2018 to the end of August 2019, with focal depths ranged between 6 and 17 km. Waveform moment tensor inversion technique was used to analyze the database constructed from seismic stations on local and neighboring country networks (Iraq, Iran, and Turkey). We separated the studie

Methicillin resistance Staphylococcus aureus (MRSA) is one of these bacteria types that emerged resistance to all current antibiotic classes. Fortunately, many studies proved phototherapy as a promising supporting to antibiotics in clinical fields.
Objectives: The purpose of this study is to evaluate the effect of three lasers wavelengths (red, blue, and green) with 50 mW power density on the susceptibility of clinical MRSA isolates.
Materials and methods: 45 clinical identified MRSA isolates are expos
A ‘locking-bolt’ demountable shear connector (LBDSC) is proposed to facilitate the deconstruction and reuse of steel-concrete composite structures, in line with achieving a more sustainable construction design paradigm. The LBDSC is comprised of a grout-filled steel tube and a geometrically compatible partially threaded bolt. The latter has a geometry that ‘locks’ the bolt in compatible holes predrilled on the steel flange and eliminates initial slip and construction tolerance issues. The structural behaviour of the LBDSC is evaluated through nine pushout tests using a horizontal test setup. The effects of the tube thickness, strength of concrete slab, and strength of infilled grout on the shear resistance, initial stiffness, and du

This research’s goal is to restore and to revive the jurisprudence of Mother of Believers (Um alMuaamineen) “Um Salmah” "may God bless her", and to highlight her outstanding assimilation and understanding of religion and her conscious thought. The current research is a comparative scientific theoretical study represented in the comparison of jurisprudence of “Um Salamah” with Hadiths of fasting and pilgrimage rules as well as the duration mentioned in jurisprudence of for doctrines( 4 schools of thought )to identify these hadiths with the inclusion and discussion of their evidence.
The current research included two topics: the first one is to identify and introduce
... Show MoreZubair Formation is one of the richest petroleum systems in Southern Iraq. This formation is composed mainly of sandstones interbedded with shale sequences, with minor streaks of limestone and siltstone. Borehole collapse is one of the most critical challenges that continuously appear in drilling and production operations. Problems associated with borehole collapse, such as tight hole while tripping, stuck pipe and logging tools, hole enlargement, poor log quality, and poor primary cement jobs, are the cause of the majority of the nonproductive time (NPT) in the Zubair reservoir developments. Several studies released models predicting the onset of borehole collapse and the amount of enlargement of the wellbore cross-section. However, assump
