Helicobacter pylori is a helix-molded gram-negative bacterium. It is a worldwide distribution. In the current study sixty serum samples from a pregnant woman with vomiting and nausea (emesis gravidarum) plus thirty pregnant without vomiting and nausea (control group) done in Kirkuk general hospital were collected to recognize IgG -H. pylori antibody by utilizing Enzyme linked immunosorbent assay. The obtained information includes age, gestational period and residence, during the period of August - December /2015.The actual study was achieved which aimed to focused the light on association of H. pylori in the pathogenesis of emesis gravidarum. The results showed that mean age ± Standard deviation for pregnant with vomiting and nausea (32.18 ± 1.8) and for pregnant without vomiting and nausea (8.7 ± 0.79). P.value < 0.05. The outcomes appeared the propagation of Helicobacter pylori IgG antibody positive in pregnant with vomit and nausea in the first-trimester of gestation was 9(42.8%) with Pvalue = 0.001 when matched with standard group while during second trimester, the H. pylori IgG antibody positiverate in emesis gravidarum group was 30(76.9) and in control group was 2(16.6%), P. value = 0.0001. The current result also reviewed a positive significant contrast between H.pylori IgG- positive and the residence, Pvalue=0.04.

In this submitted article, we defined new notions of closed sets and called it (p, q)-fuzzy αm-closed sets in double fuzzy topological spaces. Also, we investigate some characterizations and properties of the sets mentioned above. As a result, we discussed some new and more general relationship between (p, q)-fuzzy αm-closed set and it’s generalized which is called an (p, q)-generalized fuzzy αm-closed sets which was obtained and compared.

This research studies the wear characteristic of Al- based composite material. Stir casting technique was used to fabricate composite samples of Al-6061 and Al-6061 reinforced with different percentage ages (5%, 10%, 15% weight) of silicon carbide particles (SiC). Abrasive wear behavior of composite was studied by dry sliding pin on disc method. Different parameters were taken into consideration including, applied load, sliding speed, and weight percentage age of silicon carbide particles. Wear test-sliding distance ranged from 1044 m to 3123 m measured over different times (10 min, 20 min, and 30 min). Normal loads range from 10 N to 30 N, at sliding speeds of 1.74m/s. Specific wear rate was calculated considering weight loss calculation which was measured by using digital electronic balance (up to 0.01 g accuracy). The results show that by increasing the sliding speed and the applied load we get the highest wear rate in the aluminum alloy, while with the Al/SiC composite, the wear rate decreases with the increase of SiC percentage age. It was found that hardness increases simultaneously when SiC percentage age increases. The highest hardness in (AL- 15 wt. % SiC) was recorded.

Seminal fluid and blood samples were collated from sixty 20-60 years aged and attended Teba Center for Children and ICSI/ in Babylon Province during the period from 1st June 2016 to 1st February 2017. The same number of samples were also taken from 60 age matched apparently healthy individuals to act as a control group. Anti IgG levels were measured in the sera of both groups to detect the presence of Toxoplasma infection, while seminal fluid samples were examined to detect infertility. Toxoplasma gondii genotype was applied by using nested PCR to detect SAG2 gene. Gene sequencing technique infection was performed for detection occurrence of mutation in the mitochondria of the sperm. Results confirmed that the age group (20-40years) was significantly more prone P<0.05 to infective with T. gondii where the percentage of seropositivty was 65% (39 patients) while it was 35% (21 individuals) in the apparently healthy control group. Concerning the residence, there was a highly significant difference (P < 0.006) where the percentage of seropositivty was 68% in idiveduals living in rural areas while it was 32% among those living in the urban areas. Genotyping showed that presence in two strains of Toxoplasma which has been found in males infected with Toxoplasmosis.

Trace elements have an important function in the human body, where They play an role in the regulation and Stimulation of enzymatic reactions, metabolism, immunity and others. This study was conducted in the College of Science/Diyala University on women with polycystic ovarian syndrome (PCOS) from at Al-Batoul Hospital for childbirth/ Diyala. Thirty four women were diagnosed with polycystic ovarian syndrome (PCOS) based on Rotterdam 2003 criteria and were considered as patients groups. In contrast, seventeen healthy women with regular menstrual cycle and free of diseases were selected and considered as control group. Concentrations of trace elements (zinc, copper and chromium) were measured in the serum using an atomic absorption spectrophotometer in the Poisoning Consultation Center/ Medical City. The level of serum thyroid hormones [ Thyroid Stimulating Hormone (TSH), Thyroxine (T4) and Triiodothyronine (T3)] was measured using the ELISA method. The results showed a significant decrease in the mean level of zinc in the PCOS group (67.5 ± 6.9 μg/dL) compared with control group (87±8.39 μg/dL), (p < 0.01). The mean copper, Cu/Zn ratio and chromium level were significantly higher in the PCOS group (158.58 ± 8.3, 2.38 ± 0.37 and 0.218 ± 0.038 μg/dL) respectively compared with control group (118 ± 9.5, 1.37 ± 0.18 and 0.114± 0.015 μg/dL); (P <0.01) respectively. There were no significant differences in the level of thyroid hormones between the two study groups.

Data security has become a critical issue nowadays. Sensitive data needs to be hidden from unauthorized users. In recent years, various types of images are stored and transmitted via internet. This make maintains the confidentiality, integrity and authenticity of images are a major task. Many techniques have been proposed to image encryption for the secure transmission of these images. One of the effective key of the image encryption is the using of fractal images because of the random and chaotic nature of fractals. This paper presents a proposed technique for image encryption based on fractal geometry and chaotic map. The proposed method includes encryption of color image at three stages. At first stage, the plain input image is encrypted by using the concepts of fractal geometry. In the second stage, the same picture is encrypted using the one-dimensional logistic mapping functions to generate a random image depend on the randomness nature of logistic function. Finally, in the third stage, the output encrypted images of the above two stages is merge by using the X-OR operation to generate the final encrypted image with high security attributes. Experimental results of the proposed method of encrypt images show that it has many effective features such as low relations between the pixels of encrypted image, large space key and high sensitivity to key in addition to high security. Therefore, it can be effectively protecting the security of encrypted images.

This study aimed to investigate the potential association between the polymorphism of the Interlukin-6 gene (G˃C) at position + 565 SNP. and type 1 diabetes (T1D) in Iraqi patients, the study included 39 blood samples which have withdrawn from diabetic patients (12 males and 27 females and an average age of 15.65 ± 1.79 years) who were diagnosed by a medical staff at Baquba General Hospital for the period from October 2015 to March 2016 together with 21 blood samples from apparently healthy people as a control group (7 males and females and an average age of 14.26 ±1.43 years). The polymerase chain reaction-specific sequence primer (PCR-SSP) assay has been used in this study. The results revealed that comparing IL6+590 genotypes and alleles between T1D patients and controls showed some significant variance. The results of the gel electrophoresis of the IL-6 G / C + 565 gene amplified by PCR-SSP showed that the two genes G and C were present and that there were three genotypes: GG, GC, CC among patients. The results showed that frequency of GG genotype (56.41 vs 28.57%; respectively) and G allele (74.36 vs 59.52%; RR =36.7%) was significantly increased in diabetic patients in comparison with the controls (P = 0.058 and 0.102, respectively) and the related RR rates were 39.0% and 36.7%, respectively, while the associated EF values were 3.24 and 1.97, respectively.

"Oxidative DNA damage can be induced by reactive oxygen species and free radicals. Reactive Oxygen Species which is induced by oxidative damage plays a key role in DNA damage". The aim of our study is to identify the protective effect of ascorbic acid (AA, vitamin C) on hydrogen peroxide which induced oxidative damage in DNA by using the Comet assay. Lymphocytes pretreated with or without antioxidants, incubated at 37C for 30 minutes, then H2O2 (100μM) was added & incubated again at 37C for 1 hour (60 minutes). Viability of cells was detected by trypan blue stain exclusion method. The decrease in viability brought about by H2O2 when the cells incubated for 60 minutes and the viability was present to be 39±3% from 80±4% and it was highly developed by the found of AA at 100 μM which appeared 72 ± 1%. These findings indicate that the activity of ascorbic acid as an antioxidant is evidenced by its ability to suppress the oxidative effect against H2O2 and protect the lymphocytes. Estimation of comet tail moment and tail length in human lymphocyte treated with 100μM of hydrogen peroxide as positive control showed that 13± 4.5% of the cells showed no DNA damage while the DNA damage from low to very high damage were 19± 3.5%, 12.2± 2.3%, 14± 3.2% and 37± 3.0%, respectively.
