The possible association between Chlamydia pneumoniae infection and asthma.
Background: Many etiological factors have been implicated in the pathogenesis of Asthma like;Â viruses, bacteria and Chlamydia pneumoniae. This study focuses on the role of Chlamydia
pneumoniae in asthma pathogenesis.
Patients and Methods: The detection of Anti-Chlamydia pneumoniae antibodies IgA, IgM and IgG in patients by ELISA, for 35 patients, 18 asthmatic patients, 12 patients with chest infection with no history of asthma, and 5 apparently healthy as control subjects.
Results: The results showed that 80% and 70% of the patients were negative for anti- Chlamydia pneumonia antibodies IgA and IgM respectively, while significantly (p<0.05) high number (73%) of patients were positive for IgG, of which significant number (p<0.05) of them, 63% were asthmatic and 36% were non-asthmatic chest infection.
Conclusion: this study may support the association between Chlamydia pneumoniae and asthma
Molecular Detection of Helicobacter pylori by Real Time- PCR in Dyspeptic Patients
Helicobacter pylori is one of the most common infection worldwide and is associated with gastric disorders. H. pylori is genetically unstable and this reflected on its virulence factors and type of diseases. Cytotoxin associated gene A (CagA) product is a major virulence factor is thought to be associated with gastric diseases. In the present study, we used RT-PCR for rapid detection of H. pylori infection in peptic ulcer patient, the determination of CagA gene directly from gastric biopsy specimens and determining relationship between gastric cancer and H. pylori. Gastric biopsy were collected from 54 patients with disorders in digestive system from AL-Hussein teaching hospital. The results of current study showed that the presence of 16SrRNA for H. pylori was 21(38.9%), 15 of 24(62.5%) were males and 6 of 30(20.0%) were females, whereas the percentage of CagA gene was 18(33.3%), 12 of 24 (50%) were males and 6 of 30 (20%) were females by using Real time quantitative PCR in 54 biopsy specimens. These result revealed a significant difference between males and females. Our study indicated that CagA gene RT-PCR is the most specific for the detection of H. pylori in gastric biopsy specimens in patients with gastric cancer compared with 16SrRNA gene . There were significant differences (p≤0.05) in CagA positive rate, among different diseases. In this study the presence of H. pylori in patients with Gastric cancer and peptic ulcer has been demonstrated by using RT-PCR method to support the hypothesis that H. pylori has a place in etiology of gastric cancer

Interventricular mechanical dyssynchrony in dilated cardiomyopathy and its relation with left ventricular systolic dysfunction
Background: Heart failure (HF) is a major problem worldwide, and despite the optimal medical treatment, still it carries high mortality. Ventricular dyssynchrony among patient with HF portends poor prognosis. Aim of the Study: The aim is to evaluate the prevalence of interventricular dyssynchrony in patients with dilated cardiomyopathy (DCM) patients and its relation to underlying etiology and the severity of systolic dysfunction. Materials and Methods: Fifty-eight patients with ischemic and nonischemic cardiomyopathy (ICM and NCM) were included in this study. Inclusion criteria include Type II–IV New York Heart Association patients with ejection fraction (EF) <35%. Mechanical dyssynchrony (interventricular dyssynchrony) was assessed by pulsed Doppler. Assessment of left ventricular (LV) systolic function was by EF and stroke volume. Evaluation of the prevalence of mechanical indices in DCM and their relation to underlying etiology and severity of LV systolic dysfunction was done. Results: The prevalence of interventricular dyssynchrony was more in NCM than ICM. There was a nonsignificant negative correlation between this dyssynchrony and LV systolic parameters. Conclusion: Mechanical dyssynchrony indices were affected by the underlying etiology and severity of LV systolic dysfunction associated with the existence of the mechanical dyssynchrony
A Serological Study to Diagnose the Causes of Recurrent Viral and Immune Miscarriage in Aborted Women Who Attend the Shatrah General Hospital
The current study agreed with the results of the study reached by the study in Tikrit, as well as with what indicated that the highest rate of infection was within the age groups (16-25) and (20-30) respectively, and the results of the current study differed with What the researcher reached in the city of Kirkuk, which showed the highest rate of infection, falls within the age group (30-39). These differences can be related to physiological factors such as hormones and their proportions in women of lower ages compared to the higher age groups and their frequent exposure to pathogens on a continuous basis, and this causes a negative impact on the psychological state of the patient resulting in cases of repeated miscarriage of the cause. The results of the current study differed with the results of the researcher in Iran, where the highest incidence of infection was within the age group 36-45 and agreed with a study in Iraq where the highest incidence of infection was in the age group 21-25, a study in Russia and France showed the proportion of infection 78% and 46.8%, respectively

Fabrication and Testing of Pyramidal X- Band Standard Horn Antenna
Standard horn antennas are an important device to evaluate many types of antennas, since they are used as a reference to any type of antennas within the microwave frequency bands. In this project the fabrication process and tests of standard horn antenna operating at X-band frequencies have been proposed. The fabricated antenna passed through multi stages of processing of its parts until assembling the final product. These stages are (milling, bending, fitting and welding). The assembled antenna subjected to two types of tests to evaluate its performance. The first one is the test by two port network analyzer to point out S & Z parameters, input resistance, and the voltage standing wave ratio of the horn, while the second test was done using un-echoic chamber to measure the gain, side lobes level and the half power beam width. The results of testing come nearly as a theoretical value of the most important of antenna parameters, like; gain, side lobe level, -3 dB beam width, return loss and voltage standing wave ratio "VSWR", input Impedance
