Distribution and Phylogenetic Analysis of Subtypes and Alleles of Blastocystis sp. in the Stool Samples Collected from Patients with Gastrointestinal Complaints in Izmir, Turkey
No full textPurposeBlastocystis sp. is one of the most prevalent intestinal protozoa found in humans and many other animals. The present study aimed to examine the distribution and genetic diversity of Blastocystis sp. in stool samples from patients with gastrointestinal complaints in Izmir, Turkey.MethodsAll stool samples of 439 patients with gastrointestinal complaints were examined by native-Lugol and trichrome staining. To investigate the presence of Blastocystis sp. in stool samples, DNA was isolated, and PCR was performed with the barcode region in the SSU rRNA gene. PCR positive samples were sequenced to identify subtypes and alleles of Blastocystis sp.ResultsThe prevalence of Blastocystis sp. was found to be 16.6% (73/439) in patients with gastrointestinal complaints in Izmir, Turkey. Three different Blastocystis sp. subtypes were identified. ST3 (28/55; 51.0%) was the most common subtype followed by ST2 (19/55; 34.5%) and ST1 (8/55; 14.5%). Itching and diarrhea were the most prominent clinical symptoms in Blastocystis sp. positive patients. When clinical symptoms and subtypes were compared, diarrhea was found in 62.5%, 47.4%, and 46.4% of patients with ST1, ST2, and ST3 subtypes, respectively. In addition, itching was found in 37.5%, 32.1%, and 21.1% of patients with ST1, ST3, and ST2, respectively. Six distinct alleles were identified by allele analysis of Blastocystis 18S rRNA gene: allele 4 for ST1, alleles 9, 11, and 12 for ST2, and alleles 34 and 36 for ST3. In this study, Blastocystis sp. was detected in 16 of 21 districts, including the central and rural districts of Izmir. Although ST1 was detected in central districts, it was not found in rural districts.ConclusionThis study provides comprehensive data on the prevalence and molecular epidemiology of the genetic diversity at the level of subtypes and alleles of Blastocystis sp. in different districts of Izmir province in Turkey. To the best of our knowledge, this is the first study which evaluates the distribution of subtypes and alleles of Blastocystis sp. according to PCR and SSU rRNA gene sequencing in patients with gastrointestinal complaints in different districts of Izmir province in Turkey

Gastrointestinal side effect profile due to the use of alendronate in the treatment of osteoporosis
No full textThe aim of our study was to evaluate the upper gastrointestinal (GI) tract side effect profile in 759 female patients that had taken alendronate (10 mg/day), for at least 6 months, for the treatment of osteoporosis, in relation to the safety of alendronate and the compliance of patients to its absorption rules. This study was a multicentered retrospective, clinical, non-placebo controlled, study of 759 female subjects carried out at 26 centres in 6 different regions of Turkey. The mean age of our patients was 62.6 +/- 8.6, with 51.2% in the age range 60 to 69 years. 158 patients (20.8%) were considered to have upper GI tract complaints with nausea as the most often encountered symptom. Of the subjects with upper GI tract complaints, 20% reported discontinued drug use, and 30% reported the requirement of an additional drug in order to abolish their complaints. Approximately 537 (71%) of the patients stated they had been given written information about the administration of the drug, and at least 93 patients (12%) and 73 patients (18.4%) acknowledged non compliance with the safety and absorption rules, respectively. In our study, no significant difference was found between the adherence to the safety measures and upper GI tract complaints (p>0.05), but that upper GI tract complaints were higher in patients taking additional medication to alendronate (p<0.05)
Onyx: A new Canvas-based tool for visualizing biomedical and health ontologies
No full textOntologies provide formal, machine-readable, and human-interpretable representations of domain knowledge. Therefore, ontologies have come into question with the development of Semantic Web technologies. People who want to use ontologies need an understanding of the ontology, but this understanding is very difficult to attain if the ontology user lacks the background knowledge necessary to comprehend the ontology or if the ontology is very large. Thus, software tools that facilitate the understanding of ontologies are needed. Ontology visualization is an important research area because visualization can help in the development, exploration, verification, and comprehension of ontologies. This paper introduces the design of a new ontology visualization tool, which differs from traditional visualization tools by providing important metrics and analytics about ontology concepts and warning the ontology developer about potential ontology design errors. The tool, called Onyx, also has advantages in terms of speed and readability. Thus, Onyx offers a suitable environment for the representation of large ontologies, especially those used in biomedical and health information systems and those that contain many terms. It is clear that these additional functionalities will increase the value of traditional ontology visualization tools during ontology exploration and evaluation
Design of Pulsed Electromagnetic Field Generator and Applicator and the Effect of Wound Healing
No full textToday, biomedical devices have become an issue where system manufacturers are working intensively. At present, many domestic and foreign biomedical companies offer various EMA products. Electromagnetic fields (EMF) has a significant impact on our body. These fields are being used for bone problems, cartilage regeneration, and pain removal for physiotherapy purposes. Lately, EMFs are often used in in vitro and in vivo assays. In this study, in vivo test results of the applied pulsed electromagnetic fields (PEMF) with our designed Helmholtz coil array system are given. The skin wound healing conducted in rats as an experimental model provides important information for evaluating the efficacy and mechanism of these kind of treatments. For this purpose, effectiveness of PEMF compared to control groups on experimental skin healing effect was examined macroscopically. Compared with the control groups a faster wound healing process was followed by PEMF application at 75 Hz frequency
Idiopathic Brachial Neuritis in a Patient with Multiple Myeloma
No full textIdiopathic Brachial Neuritis (IBN), is a rare brachial plexopathy with an unknown aetiology. Multiple myeloma is a neoplastic plasma cell disease characterised by bone lesions. In this article, we present the case of a 59-year-old male patient with IBN associated with multiple myeloma, who was admitted to our clinic with right shoulder pain and right arm weakness. He experienced muscle weakness and atrophy in his right arm after a sudden onset of pain attack in the shoulder. Plexus and cervical vertebral MRI showed no pathology. Electrodiagnostic studies showed upper and middle trunk plexopathies. Laboratory analysis revealed anaemia, hypercalcaemia, renal dysfunction and monoclonal gammopathy in immunoglobulin electrophoresis. A bone marrow biopsy established the diagnosis of IgG kappa multiple myeloma. This is the first case report that presents the association of multiple myeloma and IBN
