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.
In this work pyrazolin derivatives were prepared from the diazonium chloride salt of 4-aminobenzoic acid. Azo compounds were prepared from the reaction of an ethanolic solution of sodium acetate and calculated amount of active methylene compound namely, acetyl acetone to obtain the corresponding hydrazono derivative (1). Cyclocondensation reaction of compounds (1) with hydrazine hydrate and phenyl hydrazine in boiling ethanol affording the corresponding pyrazoline-5-one derivatives of 4-aminobenzoic acid (2,3). Then compound (3) was reacted with thionyl chloride to give the corresponding acid chloride derivative(4), followed by conversion into the corresponding acid hydrazide derivative (5) carboxylic acid thiosemicarbazide (11), esters

The paper presents the design of a system consisting of a solar panel with Single Input/Multiple Outputs (DC-DC) Buck Converter by using Simulink dialogue box tools in MATLAB software package for simulation the system. Maximum Power Point Tracking (MPPT) technique depending on Perturb and Observe (P&O) algorithm is used to control the output power of the converter and increase the efficiency of the system. The characteristics of the MSX-60 PV module is chosen in design of the system, whereas the electrical characteristics (P-V, I-V and P-I curves) for the module are achieved, that is affected by the solar radiation and temperature variations. The proposed design module has been found to be stable for any change in atmospheric tempera

Preparation of identical independent photons is the core of many quantum applications such as entanglement swapping and entangling process. In this work, Hong-Ou-Mandel experiment was performed to evaluate the degree of indistinguishability between independent photons generated from two independent weak coherent sources working at 640 nm. The visibility was 46%, close to the theoretical limit of 50%. The implemented setup can be adopted in quantum key distribution experiments carried out with free space as the channel link, as all the devices and components used are operative in the visible range of the electromagnetic spectrum.
