In contrast to the other mutations and polymorphisms, FV Leiden, FXIII V34L, GPIIIa L33P, Apo E, prothrombin G20210A, PAI-1 and MTHFR C677T gene mutations may help to identify the couples at risk for recurrent pregnancy loss.
Anthrax, caused by the Gram-positive, rod-shaped, spore-forming bacterium Bacillus anthracis, is rarely seen in industrialized nations but is common in developing countries. Cutaneous anthrax accounts for 95% of cases and usually develops on exposed sites. This study reviews the clinical and laboratory findings of 32 patients diagnosed with cutaneous anthrax over a 4-y period in the eastern part of Turkey. All patients had a history of direct contact with infected animals. The patients, aged 6-72 y, comprised 17 (53%) males and 15 (47%) females. The most frequent localization site of skin lesions was the hands and fingers (31 patients), whereas the suborbital part of the face was invaded in 1 patient. The diagnosis was made as a result of typical clinical lesions, direct microscopy or bacterial isolation. All but 2 patients were successfully treated with penicillin; these other 2 patients were treated initially with sulbactam-ampicillin. All patients, including the patient with suborbital anthrax, were cured.
Titanium dioxide (TiO2) nanoparticles (NPs) are commonly used materials present in many consumables for which most people are exposed to. The biological hazards of the NPs on human health have been demonstrated previously. In this study, we aimed to assess the cytotoxicity potency of TiO2 NPs on the primary human amniotic fluid cells. The cells derived from amniotic fluid were treated with different dosages of TiO2 NPs for some periods. Cell adhesion status was assessed using a light microscopic observation. Cell proliferation and cell death rates were determined using trypan blue staining and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Also, mitotic index was determined using fluorescence in situ hybridization with chromosome 8 centromer-specific DNA probe. Disrupted cell adhesion, decreased proliferation, and increased mortality rates were detected in the cells that were treated with TiO2 NPs depending on the dosage ( p < 0.001). Also, reduced mitotic index was determined in the cells depending on the time and TiO2 dosage when compared with the controls ( p < 0.0001). These results showed that TiO2 NPs have high cytotoxicity for amniotic fluid-derived cells. Therefore, different products containing TiO2 NPs should be used with care, especially for pregnant women.
Objective: The purpose of this study was to evaluate the relationship between 5,10- methylenetetrahydrofolate reductase (MTHFR) polymorphisms and Attention Deficit Hyperactivity Disorder (ADHD) in a sample of Turkish children.Study Design: MTHFR gene polymorphisms were assessed in 40 patients with ADHD and 30 healty controls. Two mutations in the MTHFR gene were investigated using polymerase chain reactions and restriction fragment length polymorphisms.Results: Although there were no statistically significant differences in genotype distributions of the C677T alleles between the ADHD and the control groups (p=0,678) but the genotypic pattern of the distributions of the A1298C alleles was different between the ADHD patients and the controls (p=0,033).Conclusions: Preliminary data imply a possible relationship between A1298C MTHFR polymorphisms and the ADHD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
