In this paper, ferric oxide nanoparticles) Fe₂O₃ NPs( were synthesized directly on a quartz substrate in vacuum by pulse laser deposition technique using Nd:YAG laser at different energies (171, 201,363 mJ/pulse). The slides were then heated to 700^o C for 1 hour. The structural, optical, morphological, and electrical properties were studied. The optical properties indicated that the prepared thin films have an energy gap ranging from 2.28 to 2.04 eV. The XRD results showed no lattice impurities for other iron oxide phases, confirming that all particles were transformed into the α-Fe₂O₃ phase during the heating process. The AFM results indicated the dependence of nanoparticles size o

Background: In the last years, Endometriosis affects up to 10 percent of reproductive aged Iraqi women. Little is known about the etiology of endometriosis in Iraqi women.
Objectives: The aim of this study is to investigate the hormonal changes, antioxidant status, Coenzyme Q10 and oxidative stress in women patients with endometriosis.
Patients and methods: 30 endometriotic women mean aged (31.16±5.61 year ) who were undergoing laparoscopy to participate in this study, and (n=30) healthy women volunteers mean aged (31.96±5.42 year) as control group.
Results: The results in this study revealed a highly significant increased (P<0.01) in estradiol (E2), uric acid (UA) and oxidative stress (MDA). The results of the Coenzyme Q10

   Interleukin -33 (IL)-33 is among IL-1 cytokine superfamily , which shows promise as a biomarker predictive of mortality in diabetic and several cardiovascular disorders in vivo study.The objective of this study  is to investigate the differences in the levels of IL-33 between healthy controls and patients with type 2 diabetes and diabetic cardiomyopathy and to investigate the correlation of IL-33 with HbA1C (biomarkers of type 2 diabetes), hs-CRP  and oxidant –antioxidant status.    One hundred and fifty individuals (age 40-55) were enrolled in this study which was divided into three groups as follows: G1:50 healthy control,G2: 50 subjects with type 2 diabetes mellitus,G3: 50 patients with dia

Corncob is an agricultural biomass waste that was widely investigated as an adsorbent of contaminants after transforming it into activated carbon. In this research carbonization and chemical activation processes were achieved to synthesize corncob-activated carbon (CAC). Many pretreatment steps including crushing, grinding, and drying to obtain corncob powder were performed before the carbonization step. The carbonization of corncob powder has occurred in the absence of air at a temperature of 500 °C. The chemical activation was accomplished by using HCl as an acidic activation agent. Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), X-ray diffraction (XRD), and Brunauer–Emmett–Teller (BET) facilitate

Background: Failure of resin bases were a major disadvantage recorded in the constructed dentures. Reinforcements of the repair joint with nano fillers represent an attempt to enhance the strength and durability. The purpose of the research was to estimate the influence of nano fillers reinforcement with (ZrO2 and Al2O3) on impact and transverse strength of denture bases repaired with either cold or hot processing acrylic resin. Materials and methods: A hundred and forty (140) samples were processed with hot cured resin and organized in subgroups depending on the repair materials and condition (without repair (control), repair with hot cure, cold cure, hot and cold cure reinforced with either (5% Zr2O or 0.5% Al2O3). The samples in these

  In this  research,  We  study the effect  of  irradiation  by  gamma rays from (Cs137) source  for the period time (21) days on optical propertices such as absorption coeffeicient ()and  energy gap (Eg) for  copper oxides thin films (CuO) prepared by the chemical spray pyrolysis and deposited on glass substrates at (350oC) for two different thicknesses  (  1000Ã…and 3000Ã…) .
