H. pylori vacA s1a, cagA, cagE genotypes have significant relations with the presence of DU and GC, and iceA1, babA2 with GC in Turkish patients with dyspepsia, whereas cagE and vacA s1a genotypes are independent predictors of DU, and babA2 and cagE genotypes are independent predictors of GC.

Juvenile idiopathic arthritis (JIA) is a disease that was prominent with increased inflammation response in immune system, appeared mostly with peripheral arthritis and endogenous and exogenous antigens play a role in the pathogenesis of disease. Two major reasons were thinking to be considerably important. First of them is immunological predisposition and the second one is environmental factors. Infections are considered to be the most important between environmental factors but also stress and trauma are also important in the etiology of the disease. However, the relation between JIA and infections is not clearly defined but the relation between adult chronic arthritis and infections was well-defined. A total of 70 patients, 26 with primer JIA, 20 with recurrent JIA, 24 healthy control were included in this study. Mycoplasma pneumoniae, Chlamydophila pneumoniae and C. Jejuni were detected in 4, 1 and 1 of 10 (38.46%) patients with primer JIA, respectively. Salmonella enteritidis, EBV, M. pneumoniae, C. jejuni and Borrelia burgdorferi were detected in 1, 2, 2, 2, and 1 of the 8(40%) patients with recurrent JIA, respectively. S. enteritidis were isolated in feces culture and also identified by agglutination method. Infection was detected in total 18 (39.13%) of patient groups. C. pneumoniae and C. jejuni were detected in 1 and 1 of 2(8.33) healthy control groups, respectively. Throat culture positivity was not detected in any of the patient and healthy control groups. In conclusion, etiopathogenesis of JIA is not clearly understood and suggested that various factors can trigger the disease and it is the most common rheumatoid disease of childhood. However, there are some studies focusing especially on one infectious agent but this is the first study including such a big range of infectious agents in the literature for the microorganisms that can be suggested to have a role in the etiopathogenesis of JIA. We have a conclusion in the light of our results and suggest that some microorganisms can trigger and increase the intensity of clinical situation according to the case. When we evaluate the primer and recurrent JIA groups; M. pneumoniae and C. jejuni come forward and seen common in JIA cases. We also suggest that the pre-diagnosis of microorganisms, which can play a role as primarily or by intervening in the etiopathogenesis of JIA and adding specific antimicrobial therapy to the standard JIA therapy, it is possible to perform new, extended, especially molecular based serial case studies.

Abstract:We assessed igg antibody to Toxoplasma gondii in 300 inpatients with schizophrenia (SG), 150 outpatients with anxiety and depressive disorders (PCG), and 150 healthy blood donors (HCG). Seropositivity rates were 60.7% for SG, 36.7% for PCG, and 45.3% for HCG (p<0.001). The seropositivity rate for anti-Toxoplasma IgG antibodies in SG was significantly higher that in PCG (X 2 = 23.11, OR = 2.66, p = 0.001) and HCG (X 2 = 9.52, OR = 1.86, p = 0.002). Among SG, 85% of those who reported close cat contact had igg antibodies to T. gondii. Close cat contacts were reported by 59% of SG, 6% of PCG, and 9% of HCG (p<0.001). There was a nonsignificant positive association between toxoplasmosis and schizophrenia for people with a contact with a cat (or = 2.221, p = 0.127, ci 95 = 0.796-6.192), and significant negative association between toxoplasmosis and schizophrenia for people without contact with a cat (OR = 0.532, p = 0.009, CI 95 = 0.332-0.854). Close cat contact (OR = 2.679, p<0.001), 51-65-year age group (OR = 1.703, p<0.001) and education [illiterate+primary (OR = 6.146, p<0.001) and high school (OR = 1.974, p = 0.023)] were detected as independent risk factors in multivariate logistic regression. The effect of toxoplasmosis on risk of schizophrenia disappeared in the complex model analyzed with multivariate logistic regression. In conclusion, our data suggest that the toxoplasmosis has no direct effect on the risk of schizophrenia in turkey but is just an indication of previous contacts with a cat.

When analyzed together with host genetic factors, the well established bacterial risk factor babA2 seems to be the most important predictor of malignant disorders, and the presence of the IL-1B-31TT genotype emerges as a protective factor against them.

Abstract. 136 stars which were known to be the members of open cluster NGC 752 were observed at R band with ROTSEIIId telescope located at the Turkish National Observatory (TUG) site. The data had been evaluated together with BV and 2MASS photometric data. A new practical method for separating dwarf and giant was described and applied. Evaluating the colour magnitude-diagrams with Padova isochrones revealed metallicity similar to the Sun and an age of 1.41 Gyr for the open cluster NGC 752.

The monoclonal FemtoLab H pylori test, using a cut-off 0.19, is a very sensitive, specific and easy to perform diagnostic tool for the primary diagnosis of H. pylori infection in Turkish patients with dyspepsia.
