Nowadays nanoparticles have widespread application in various industries because of their special and unique features, there are many studies in side effects of nanomaterial. This study done by 40 white female mice with every other day intraperitoneally injection of low and high doses of both of ZnO kg of body weight) and FeO nanoparticles (5 and 40 mg/kg). After a 15 days period, the mice were sacrificed and blood samples were collected for hormone analysis, and tissue samples for morphometric studies. Statistical Analysis shows significant differences in LH, Estrogen, Progesterone hormone levels between groups, while there are insignificant differences in Follicle stimulating hormone (FSH) level between the groups compared with its level in the control group. The results also show that the highest level of LH reach 7.2 mIU/ml in the groups treated with low dose of zinc oxide, the highest level of FSH reach 4.58 mIU/ml in the groups treated with low dose of zinc oxide, the highest level of Estrogen hormone reach 69.5 ng/ml in the groups treated with low of dose zinc oxide and the highest level of Progesterone reach 1.9 ng/ml in the groups treated with high dose iron oxide. We conclude from the results that the low doses of ZnO has benefits in increasing fertility through highlevel of reproductive hormones, while the high levels of nanoparticles reduce fertility and there is a relation between FeO nanoparticles and progesterone levels which may need more future studies. Morphometric study of the ovary show increase in Follicular stages number range in the group treated with Low dose ZnO in compare with its range in the control groups. The lower range was belong to the group treated with the high dose of FeO. No significant differences has been found in the diameter mean of the different follicular phases between the group treated with low dose of ZnO NPs in compared with the control group. High dose of ZnO NPs cause significant increase in the diameter mean of Primordial follicles in compared with the control group. Low and high dose FeO NPs treated groups show significant reduction in the diameter mean of the different follicular phases in compared with the control group.

The present work was aimed to form the baseline data of normal morphological and histological structure features of liver in migratory starling (Sturnus vulgaris). Anatomically, the starling liver bird was dark red -brown in colour and located in the cranial third of the abdominal cavity and consisted of undivided lobes (left and right). The liver right lobe was larger than the left. Histological examination revealed that the liver parenchyma was covered by a connective tissue capsule which appears to be thicker in the rim of liver lobes than other area in the liver lobe. Liver parenchyma was arranged in an unlimited hepatic lobules, which composed of polygonal hepatocytes organized as irregular, radial interconnecting cords or laminae of one or two cells thickness around a central vein and separated by blood sinusoids. In the boundary of each lobule showed a portal area which consists of a branch of hepatic artery; one or more branches of hepatic vein and one to four branches of the bile duct which lining by cuboidal cells that characterized by their empty non-staining cytoplasm. The histochemical observation by using PAS staining in the current study revealed that the glycogen granules arranged close to the central vein and in the rim of liver lobules.

In the course of pregnancy, the developing fetus might have some infections that can be transmit to him transplacentally from his mother. Early identification and treatment of these infections in a neonates is essential. Prenatal caution comprehends a range of tests, involving a TORCH screen test. From the beginning of July till the end of December 2014. 500 blood samples were collected for TORCH screening from pregnant women whom attended virology section in Azadi Teaching Hospital. The TORCH screening was performed using ELISA technique. The result of TORCH screening tests was not differed significantly between year 2013 and 2014, but there was significant differences between the frequency of the microorganisms included in TORCH screening, the highest was for Cytomegalovirus and Rubellawith rates of 29.2, 39.1 % and 30.3, 41.8 % for each of the two viruses respectively. Lower frequency was observed for Toxoplasmawith rate of 9.5, 8.9 % followed by Herpes simplex virus with a rate of only 1.1, 2.6 %. High rate of mixed infection were between Cytomegalovirus and Rubella. The frequency of chronic infections were significantly higher comparing with acute and subacute cases. The rate of infections was not effected by patients age. Cytomegalovirus, Rubella and Toxoplasmaare prevalent among pregnant women in Kirkuk city and probably they are the causative agents of abortion and infertility found among them, therefore it's better for pregnant woman or those planning to become pregnant to be tested for TORCH infections, and vaccinated against Rubella ,Cytomegalovirus, Herpes simplex virus and Toxoplasma to grantee her health as well as her baby

This work, presents four kinds of adjoint representations for the special unitary matrix Lie group SU(2) and the special unitary, special linear matrix Lie algebras su(2) and sl(2). In the first two we assume the vector spaces as the matrix Lie algebras su(2) and sl(2), later cases obtained by exploiting the action of su(2) and sl(2) on themselves. Also, we compute their direct sums. The results have been displayed as Tables in a nice form.

Z-scan technique was employed to study the nonlinear optical properties (nonlinear refractive index and nonlinear absorption coefficient) for crystal violet doped polystyrene films as a function of doping ratio in chloroform solvent. Samples exhibits in closed aperture Z-scan positive nonlinear refraction (self-focusing). While in the open aperture Z-scan gives reverse saturation absorption (RSA) (positive absorption) for all film with different doping ratio making samples candidates for optical limiting devices for protection of sensors and eyes from energetic laser light pulses under the experimental conditions.

In this research, X-ray diffraction of the powder (PVP polymer, Eosin B dye, and silver nitrate) and (EB/PVP, AgNO3/PVP, EB/AgNO3/PVP) films have been studied. Casting method is used to prepare homogeneous films on plastic petri dishes. All parameters accounted for the X-ray diffraction; full width half maximum (FWHM), Miller indices (hkl), size of crystalline (D), Specific Surface Area (S) and Dislocation Density (δ).The nature of the structural of materials and films will be investigated.
