Cystic echinococcosis (CE) is one of the most important zoonotic parasitic diseases caused by the larval stage of Echinococcus granulosus. Based on molecular studies and DNA sequencing, E. granulosus has been classified into 10 different genotypes (G1 to G10). Two neighboring countries, Turkey and Iran, are considered the two main foci of CE in the Middle East. The current study is aimed at examining the genotype diversity of E. granulosus isolated from human clinical samples in Turkey and Iran. Surgically removed human hydatid cysts were collected from East Azerbaijan and Fars provinces in Iran and Van province in Turkey. After extracting DNA, performing PCR, targeting the cox1 gene, the PCR products were purified from the gel and were sequenced from both directions. The sequences were aligned and compared, using BioEdit and also the BLAST program of GenBank. The maximum likelihood tree was constructed based on the Tamura-Nei model, using the MEGAX software. Phylogenetic analysis showed that the human isolated samples were classified into two major clades: G1 (from Iran and Turkey) and G3 (5 samples from northwestern Iran and one sample from Turkey). The mean and degree of genetic divergence (K2P) between the two major clades, G1 and G3, were 0.2% and 0.7±0.4%, respectively. The findings of the current study revealed that the sheep strain (G1) and the less important strain G3 have major roles in the transmission cycle of CE in two neighboring countries, Iran and Turkey. Therefore, it is necessary to interpose the life cycle of this parasite and reduce the disease burden in livestock and humans by adopting common regional preventive and control policies.

5-bromo-2-(prop-2-yn-1-yloxy)benzaldehyde (compound 3) and 3,5-di-tert-butyl-2-(prop-2- yn-1-yloxy)benzaldehyde (compound 5) were synthesized via nucleophilic substitution reactions. Compound 5 showed higher antioxidant capacity with respect to compound 3 in all the four different antioxidant activity methods used. Moreover, in phosphomolybdenum assay, compound 5, with 1.1 proportion value, showed almost the same total antioxidant capacity compared to universal trolox standard. Furthermore, Broth microdilution method and agar disc diffusion tests demonstrated that the same compound also exhibited good antibacterial activity towards the bacteria Bacillus subtilis. Finally, both of the benzaldehyde compounds showed high antifungal activity against Aspergillus niger. In this study, compound 5 (IC50: 54.3 µg/ml) showed significant cytotoxic activity against breast adenocarcinoma cell line MCF-7 with respect to compound 3 (IC50: 173.4 µg/ml).

1-Methyl-2-(2-(prop-2-yn-1-yloxy)benzylidene)hydrazine analogues were readily prepared in good yields by the reaction of 2-(prop-2-yn-1-yloxy)benzaldehydes and methyl hydrazine. The reaction tolerates a variety of substituents on the 2-hydroxybenzaldehyde to form nitro-, halo-, methoxy-, and naphthyl-substituted 1-methyl-2-(2-(prop-2-yn-1yloxy)benzylidene)hydrazines. The in vitro antioxidant capacity measurements revealed that among all the analyzed hydrazine analogues that surpassed the Trolox standard, 1-(2-(but-3-ynyl)-5-nitrobenzylidene)-2-methylhydrazine had the maximum value, which was approximately 1.7 times that of Trolox.

The present study aims to investigate the effect of amount of lateralization and/or anteversion of the point where the iliac cut meets with the posterior column cut of periacetabular osteotomy (PAO), on X-ray parameters such as Center of edge (CE) angle, retroversion index (RVI) and sharp angle. Fourteen patients with symptomatic hip dysplasia (CE° < 20°) were included. Pelvis Computerized tomography (CT) sections were used for 3D printing. PAO was then performed on these models. The point (A), 1 cm lateral to the pelvic brim, is marked where the iliac cut intersects the posterior column cut. In Group I (1.5–0), point A is lateralized parallel to the osteotomy line for 1.5 cm. In Group II (1.5–0.5), it is additionally anteverted for 0.5 cm. In Group III (3–0), point A is lateralized for 3 cm and then additionally anteverted for 1 cm (Group IV: 3–1). Radiographs were taken in each stage. The lateral CE angle, RVI and sharp angle were measured. All had an increase in the CE angle and RVI and a decrease in the sharp angle compared to the control group (P < 0.05). The amount of CE angle (ΔCE) or RVI increase (ΔRV) was as follows: 3–1(38°, 0.3) > 3–0(27°, 0.2) and 1.5–0.5(25°, 0.1) > 1.5–0(17°, 0.07) (P < 0.05) (with no difference between groups 1.5–0.5 and 3–0, P = 0.7). The amount of sharp angle decrease was as follows: 3–1(20°), 3–0(18°) < 1.5–0.5(11°) < 1.5–0(8°) (P < 0.05). The lateralization of the intersection point where the iliac wing cut meets with the posterior column cut along the cut surface led to an increase of lateral cover and focal retroversion. Additional anteversion leads to further increases in those parameters, while groups 1.5–0.5 and 3–0 did not differ between.

In this study, it has been aimed to determine the knowledge level of the students of Van Yuzuncu Yıl University Health Services Vocational School, who will serve as the health personnel of the future, about parasitic diseases, prevention and control measures from these diseases. A total of 587 students, comprising 418 (71.2%) females and 169 (28.8%) males, studying at Van Yüzüncü Yıl University Health Services Vocational School, were included in the study. The questions in the questionnaire were arranged in three groups, as those about parasitic diseases, transmission routes of these diseases, and prevention and treatment. Cronbach alpha coefficients were calculated within the scope of the reliability analysis of the questionnaire questions. The Cronbach alpha values for the domains of Knowledge Level About Parasitic Diseases, Knowledge Level About the Transmission of Parasitic Diseases, and Knowledge Level About the Prevention and Treatment of Parasitic Diseases were determined as 0.647 (64.7%), 0.707 (70.7%), and 0.566 (56.6%), respectively. A statistically significant difference was found between the departments included in the study in terms of the level of knowledge about parasitic diseases (P < 0.05). A statistically significant difference was found between the departments in the evaluation made between the level of knowledge about the prevention and treatment of parasitic diseases and the personal characteristics of the students (P < 0.05). As the result, it was observed that the students participating in the study did not have sufficient knowledge about parasitic diseases.

Background: We aimed to determine the frequency and subtype of B. hominis in diabetic patients. Methods: One hundred and fifty diabetic patients and 100 healthy people without any chronic disease were included in the study. Stool samples were analyzed by native-Lugol, condensation, trichrome staining and PCR methods. Results: İn 150 patients with diabetes; B. hominis was detected in 38 (25.3%) by PCR, in 34 (22.7%) by native-Lugol and trichrome staining. In the control group, 14 (14%) out of 100 subjects were positive by PCR, and 10 (10%) were positive by native-Lugol and trichrome staining. In the statistical evaluation, a significant difference was found between gender (P=0.023), age (P=0.045; ≤35 and >35 comparison), duration of diabetes (P=0.04), the HbA1c value (P=0.023; <8 and ≥8 comparison), and B. hominis positivity. ST1 was determined in 76.9% of patients with diabetes, and ST2 was determined in 23.07%. Considering the 3 methods, B. hominis positivity was detected in 40 patients (26.7%) in diabetic group and in 14 participants (14%) in the control group (P=0.011). Conclusion: B. hominis is a factor to be considered in patients with diabetes. Herein, the most common subtype detected in the patients with diabetes mellitus was ST1, but this result was not considered sufficient to reveal the importance of the subtype factor in the pathogenicity of B. hominis in patients with diabetes. In this context, there is a need for more comprehensive studies in both diabetic and other immunocompromised patient groups.
