Evaluation of the Relationship Between the Maxillary Sinus and Nasopalatine Canal of Maxillary Impacted Canines by Cone Beam Computed Tomography

Introduction. One of the critical parameters evaluated while planning orthodontic treatment for impacted canines in clinical practice is the relationship between impacted canines and adjacent anatomical structures. The nasopalatine canal (NPC) and maxillary sinus are anatomical formations that may be in close proximity to impacted canines. This study aimed to determine the relationship between palatally impacted canines, the maxillary sinus, and the NPC. Methods. A total of 105 impacted canines from 93 patients were evaluated using cone beam computed tomography (CBCT) images. The relationship between the impacted canine teeth, maxillary sinus, and NPC was assessed inside, outside, and at the border of the maxillary sinus floor and NPC walls. The millimetric distance between the impacted canine teeth and the borders of the maxillary sinus, the NPC, and the cortical bone of the palate was measured. Additionally, NPC morphology was assessed on the axial and sagittal CBCT images. Results. Of all the impacted teeth, 47.6% (3.8% inside, 43.8% at the border) were associated with the sinus, while 42.8% (15.2% inside, 27.6% at the border) were associated with the NPC. A significant moderate negative correlation (-0.32) was observed between age and the distance between impacted left canine teeth and the cortical bone of the palate. Additionally, when a Y-shaped NPC was present, the impacted canines were predominantly situated outside the canal. Conclusions. In this study, nearly half of the canines were located inside or at the border of the maxillary sinus and the NPC. Therefore, clinicians should carefully evaluate the relationship of impacted teeth with the maxillary sinus and the NPC during both orthodontic treatment and the extraction of impacted teeth

Investigation of Extended-Spectrum Beta-Lactamase (Esbl) in Nosocomial Gram-Negative Bacterial Isolates by Different Test Methods

The aim of this study is to investigate the existence of extended-spectrum beta-lactamase (ESBL) in nosocomial Gram-negative bacteria isolates and to compare different test methods that detecting ESBL. The strains producing the largest quantities of these enzymes are Klebsiella pneumoniae (K. pneumoniae), Klebsiella spp., and Escherichia coli (E. coli). [Med-Science 2015; 4(3.000): 2431-40

Reference Intervals for Serum Immunoglobulin (IGA, IGG, IGM) and IGG Subclasses in Healthy Subjects

Aim: Regional reference values of immunoglobulin and immunoglobulin subgroups are necessary for clinical research and diagnosis. A main problem in determining the reference intervals, reference values show variability depending on laboratory and technical conditions against interregional and reference populations. In clinical laboratories mainly test kit's reference intervals are used according to the manufacturer. In this study it is aimed to determine reference interval values of regional immunoglobulin and IgG subgroups

Bilateral parotitis in a patient under continuous positive airway pressure treatment

Abstract Background and objectives: Many conditions such as bacterial and viral infectious diseases, mechanical obstruction due to air and calculi and drugs can cause parotitis. We present a case of unusual bilateral parotitis in a patient under non-invasive continuous positive airway pressure (CPAP) therapy for chronic obstructive pulmonary disease exacerbation in intensive care unit. Case report: A 36-year-old patient was admitted to intensive care unit with the diagnosis of chronic obstructive pulmonary disease exacerbation. Antibiotherapy, bronchodilator therapy and non-invasive positive pressure ventilation were applied as treatment regimen. Painless swellings developed on the 3rd day of admission on the right and a day after this on the left parotid glands. Amylase levels were increased and ultrasonographic evaluation revealed bilateral parotitis. No intervention was made and the therapy was continued. The patient was discharged on the 6th day with clinical improvement and regression of parotid swellings without any complications. Conclusions: Parotitis may have occurred after retrograde air flow in the Stensen duct during CPAP application. After the exclusion of possible viral and bacteriological etiologies and possible drug reactions we can focus on this diagnosis

Evaluation of CFTR gene mutations in Adana

ABSTRACT Objective: Cystic fibrosis is the most common autosomal recessive inherited disorder seen in the white populations. It develops in result of mutations of cystic fibrosis transmembrane regulator (CFTR) gene. Rate of these mutations vary in different geographical regions. In this study, we aimed to determine the frequency of CFTR gene mutations in Adana. Methods: DNA samples of 63 subjects (21 women, 42 men) who were diagnosed as cystic fibrosis at Balcali Hospital of Cukurova University, were studied for 19 different CFTR mutations by the strip assay method which is based on reverse hybridization. Results: In cystic fibrosis diagnosed patients, 19 mutations were observed of which 9 were homozygous and 10 were heterozygous. ∆F508 frequency was found as 11.9%, and rate of homozygous was found as 66.7%. Mutation frequencies of W1282X and N1303K were found as 2.40% and 4.80% respectively and rate of homozygous mutations were 50% for both. I148T mutation frequency was found as 3.20% and all were heterozygous. For the whole 19 mutations, frequency of mutation in 63 subjects was 22.3%. Conclusion: Detection of CFTR gene mutations by the strip assay method by reverse hybridization is an easy, fast and informative method. However, due to improvability of the common mutations in probable cystic fibrosis patients because of heterogenity in this region, it is still a major problem and does not exclude cystic fibrosis diagnosis. But this problematic issue can be overcome by evaluating the whole exons of CFTR mutations by advanced molecular tecniques. Key words: CFTR, cystic fibrosis, molecular diagnosis, reverse hibridisation [Cukurova Med J 2013; 38(2.000): 202-208

Induction of Gentiana cruciata hairy roots and their secondary metabolites

WOS: 000291479400007Gentiana cruciata L. (cross gentian) is a medicinal and ornamental plant. The root extracts of this species are known to exhibit many curative properties. The natural Gentiana populations are exposed to great danger because of their uncontrolled usage. In this study, hairy roots from Gentiana cruciata L. stem and leaf explants belonging to three different clones were induced by inoculation with four different Agrobacterium rhizogenes wild strains namely A4, 15834, 8196 and R1000. Induction of the root transformation was significantly dependent on the explant type used. On the other hand, the genotype and bacterial strain had no significant effect on hairy root formation. Hairy root formation percentages of the explants varied between 5.6-33.3% in the stem explants, and between 0.0-6.7% in the leaf explants. Transformations of the hairy roots were confirmed by PCR using rolC specific primers, and revealed the absence of contaminating A. rhizogenes with virC primers. Total of twelve hairy root clones were obtained, and their secondary metabolite content was also analyzed by HPLC. Quantitative results exhibited that gentiopicroside was the most abundant compound in all root samples. Furthermore, metabolites such as loganic acid, swertiamarin, and sweroside were also identified and quantified in the samples.Scientific and Technological Research Council of Turkey (TUBITAK-TOVAG)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [106O111]; Ege University Scientific Research Projects CommissionEge University [05MUH016]This research was sponsored by The Scientific and Technological Research Council of Turkey (TUBITAK-TOVAG 106O111) and Ege University Scientific Research Projects Commission (05MUH016).
