The objective of this study was to assess the levels of antiMullerian hormone (AMH), Follicle stimulating hormone (FSH), testosteron, luteinizing hormone (LH), and estradiol (E2) as markers of spermatogenesis between fertile and infertile males. This study was conducted at (AlRamadi Teaching Hospital for maternity and children) and included 136 males partners of infertile couples. Samples were classified according to the WHO criteria of semen analysis into three groups; Azoospermia, Oligospermia, and normal(control). Assay levels of these hormones were made in the serum and the semen of each sample. The results showed that the level of AMH in serum samples was non-significantly decreased (P>0.05) in both Azoospermia and Oligospermia groups compared to control (6.74±3.21 ng/ml and 6.01±0.25 ng/ml vs. 12.81±7.69 ng/ml). While FSH and LH levels, there were non-significantly(P > 0.05) increased in both azoospermia and Oligospermia compared to control (FSH: 12.11±8.14 mIU/ml and 7.22±6.06 mIU/mlvs.3.14±1.27 mIU/ml; LH: 10.04±7.23 mIU/ml and 7.62±3.30 mIU/ml vs.5.57±2.03mIU/ml).In addition, there were non- significant differences (P> 0.05) of testosterone hormone level among the studied groups. Such, there was a non-significant decreased level of E2 (P> 0.05) in both Azoospermia and Oligospermiagroups compared to control (170.49±37.57 ng/ml and 137.20±53.92 ng/ml vs. 194.91±41.66 ng/ml).İn contrast to semen samples, the results of AMH showed a significant (P< 0.05) decreased level in both Azoospermia and Oligospermia compared to control (8.24±4.17 ng/ml and 8.85±4.79 ng/ml vs. 13.33±0.77 ng/ml). FSH level was non-significant (P> 0.05) increased in Azoospermia and Oligospermia compared to control (3.97±1.91 mIU/ml and 4.09±2.50 mIU/ml vs. 2.47±1.29 mIU/ml). Such, there were non-significant (P> 0.05) increased levels of LH and testosterone hormones in both Azoospermia and control compared to Oligospermia (9.35±6.02 mIU/ml and 5.99±4.43 mIU/ml vs. 4.06±2.82 mIU/ml), and significant (P< 0.05) increased level of E2 in both Azoospermia and Oligospermia compared to control (241.36±35.32 ng/ml and 220.86±48.96 ng/ml vs. 170.71±73.52 ng/ml).The study concluded that the AMH, FSH and E2 hormones levels in serum and semen samples may have been associated with the sperm production and may be a good marker for spermatogenesis, as well as Sertoli cell development. In addition, the age played a critical role in the level of the studied hormones.

Magnetohydrodynamic (MHD) effects of unsteady blood flow on Casson fluid through an artery with overlapping stenosis were investigated. The nonlinear governing equations accompanied by the appropriate boundary conditions were discretized and solved based on a finite difference technique, using the pressure correction method with MAC algorithm. Moreover, blood flow characteristics, such as the velocity profile, pressure drop, wall shear stress, and patterns of streamlines, are presented graphically and inspected thoroughly for understanding the blood flow phenomena in the stenosed artery.
The adsorption study of thymol, was carried out at (25±0.1) °C, using granulated surfactant modified Iraqi Na – montmorillonite clay (initiated modified bentonite); in a down-flow packed column, the modified mineral was characterized by FT-IR spectroscopy. A linear calibration graph for thymol was obtained, which obey Beer's law in the concentration range of 5-50 mg/L at 274 nm against reagent blank. Single-factor-at-a-time approach; showed that the equilibrium time required for complete adsorption was 45 minute with flow rate (4.0drop/ mint). The adsorption of thymol increased with rising pH of the adsorbate solution, increase of solute uptake when the initial adsor

Show MoreThe present study was designed to investigate the possibility of exploiting the interspecies interaction of microbial cells in order to enhance the production of prodigiosin by local isolate S. marcescens S23. Prodigiosin is a promising drug owing to its characteristics of antibacterial, antifungal, immunosuppressive and anticancer activities. S. marcescens S23 was isolated from soil sample and already recognized via morphological, biochemical and molecular identification process. The first step was to detect the optimal conditions for maximum prodigiosin production using chemically defined liquid medium. The results revealed that the optimal conditions for prodigiosin production were sucrose as carbon source; peptone as nitrogen source;

Recent studies have shown the possibility of using polyphenol oxidase in catalytic biological treatment due to its ability to oxidize a large number of dyes and pollutants in wastewater and the flexibility to work in wide ranges of temperature, pH and salinity. It is easy availability as well as the low economic cost resulting from its use in biological treatments, this enzyme polyphenol oxidase was used. The findings in this study showed that the extraction of polyphenol oxidase (PPO) from potato peel was homogenized with potassium phosphate buffer (0.1 M, pH 7) at a ratio of 1:10 (weight: volume) for two min.

In the present investigation, the synthesis of copper nanoparticles from green tea was attempted and investigated for its capacity to adsorb drugs (Ciprofloxacin). The copper nanoparticles (Cu-NPs) were characterized by different techniques of analysis such as scanning electron microscopy (SEM) images, atomic force microscope (AFM), blumenauer-emmer-teller (BET), fourier transform infrared (FTIR) spectroscopy, and zeta potentials techniques. Cu-NPs lie in the mesoporous material category with a diameter in the range of 2-50 nm. The aqueous solution was investigated for the removal of ciprofloxacin (CIP) with green tea-synthesized Cu-NPs. The results showed that ciprofloxacin efficiency depe

A novel demountable shear connector for precast steel-concrete composite bridges is presented. The connector uses high-strength steel bolts, which are fastened to the top flange of the steel beam with the aid of a special locking nut configuration that prevents bolts from slipping within their holes. Moreover, the connector promotes accelerated construction and overcomes the typical construction tolerance issues of precast structures. Most importantly, the connector allows bridge disassembly. Therefore, it can address different bridge deterioration scenarios with minimum disturbance to traffic flow including the following: (1) precast deck panels can be rapidly uplifted and replaced; (2) connectors can be rapidly removed and replaced; and (
