Molekularno otkrivanje i genomska svojstva psećeg virusa Torque teno u Turskoj

Torque teno virus (TTV) was first detected in humans, and since then it has been reported in many host species, such as monkeys, cats, pigs, seagulls and dogs. The aim of this study was to investigate the presence of Torque teno canis virus (TTCaV) in shelter dogs housed in Sivas Municipal Animal Shelter, Turkey. Faecal specimens, including diarrheic and non-diarrheic (n=202), were collected from dogs of various age groups. In total, 32.18% (65/202) of samples were found positive for TTCaV. Out of the 65 positive samples, 34.64% (44/127) samples were from adult diarrheic dogs and 26.09% (6/23) belonged to diarrheic puppies. On the other hand, 28.84% (15/52) positive samples were detected from clinically healthy dogs. Eight sequences showed close homology among themselves, however, the sequences of two samples (CANEL130 and CANEL140) were genetically distinct from other published sequences. This is the first report on the detection of TTCaV in adult dogs and puppies in Turkey, and provides evidence that TTCaV cannot be considered as the sole cause of diarrhea.Virus Torque teno (TTV) otkriven je najprije u ljudi, no otada je zabilježen i u mnogim drugim domaćinima kao što su majmuni, mačke, svinje, galebovi i psi. Cilj ovoga rada bio je istražiti prisutnost psećeg virusa Torque teno (TTCaV) u pasa u azilu Sivas Municipal Animal Shelter u Turskoj. Uzorci izmeta (n = 202), uključujući one s proljevom i bez proljeva, prikupljeni su od pasa različitih dobnih skupina. Ukupno je 32,18 % (65/202) uzoraka bilo pozitivno na TTCaV. Od 65 pozitivnih uzoraka njih 34,64 % (44/127) potjecalo je od odraslih pasa s proljevom, a 26,09 % (6/23) od štenadi s proljevom. S druge strane, 28,84 % (15/52) pozitivnih uzoraka utvrđeno je u klinički zdravih pasa. Osam je sekvencija pokazalo međusobnu blisku srodnost, no sekvencije dvaju uzoraka (CANEL130 i CANEL140) genetski su se razlikovale od drugih sekvencija. Ovo je prvi nalaz TTCaV u odraslih pasa i štenadi u Turskoj i dokazuje da se TTCaV ne može smatrati jedinim uzročnikom proljeva

Türkiye'deki köy tavuklarında i̇nfeksiyöz laringotrakeitis virüsünün moleküler tespiti ve karakterizasyonu

Gallid herpesvirus I (GaHV1) is etiological agent of infectious laryngotracheitis (ILT) and ILT is one of the important disease that included in respiratory infections of chickens. Few studies have been conducted in Turkey and there is no data about the existence of ILT in backyards. The purpose of the study was to document the detection and characterization of GaHV1 in backyard chickens using PCR, RFLP and sequencing. Of the163 tracheal swap samples which were taken from 43 backyard flocks 5 (3.07%) were found to be positive for ILT infection. Positivity was 4.65 % (2/43) at flock level. The nucleic acid sequences of the ICP4 gene compared with ILTV sequences in GenBank and the level of identity differed from 96.82 to 100%. When the sequences of samples compared with TCO strains 99.77-100% homology was observed. The virtual RFLP analysis with the HgaI restriction enzyme characterized strains as having a pattern similar to the vaccine strain TCO. This is the first study that presents presence and characterization of GaHV1 in backyards. Large scale studies are needed to estimate prevalence of ILT in Turkey. Chickens should be monitored and growers should avoid to contacting vaccinated birds with non-vaccinated chickens, to control ILTV outbreaks.Gallid herpesvirüs I (GaHV1), infeksiyöz laringotrakeitisin (ILT) etiyolojik ajanıdır ve ILT, tavukların solunum yolu enfeksiyonları arasında yer alan önemli hastalıklardan biridir. Türkiye'de çok az çalışma yapılmış ve köy tavuklarında ILT'nin varlığına dair veri bulunmamaktadır. Çalışmada, köy tavuklarında PCR, RFLP ve sekans verileri kullanarak GaHV1'in tespitini ve karakterizasyonu amaçlandı. Toplamda 43 köy tavuğu işletmesinden alınan 163 trakeal swap örneğinin 5'inde (% 3,07) ILT enfeksiyonu pozitif bulundu. Sürü düzeyinde pozitiflik % 4,65 (2/43) idi. ICP4 geninin nükleik asit dizileri GenBank'taki ILTV dizileri ile karşılaştırıldığında benzerlik % 96.82 ile % 100 arasında değiştiği görüldü. Örneklerin sekans dizileri TCO suşları ile karşılaştırıldığında % 99.77- 100 homoloji gözlemlendi. HgaI enzimi ile yapılan sanal RFLP analizinde, çalışmadaki suşlar TCO aşı suşuna benzer bir paterne sahip olarak karakterize edildi. Bu araştırma, köy tavuklarında GaHV1'in varlığını ve karakterizasyonunu ortaya koyan ilk çalışmadır. Türkiye'de ILT prevalansını tahmin etmek için büyük ölçekli çalışmalara ihtiyaç vardır. ILTV salgınlarını kontrol etmek için tavuklar izlenmeli ve yetiştiriciler aşılanmamış tavuklarla aşılanmış olanların temas etmesinden kaçınmalıdır

Intravesical Treatment Modalities in Bladder Cancer: Current and Future Perspectives

Non-muscle-invasive bladder cancers encompass the pathological stages of Ta, T1, and carcinoma in situ. To prevent recurrence, intravesical therapy, which is performed after complete transurethral resection, is the current standard therapy for non-muscle-invasive bladder cancers. In patients with low-risk non–muscle-invasive bladder cancer, post-transurethral resection (TUR) management is a single immediate intravesical instillation of chemotherapy alone. For an intermediate-risk patient, a 6-week course of induction intravesical chemotherapy or immunotherapy can be adapted. Bacillus Calmette-Guerin vaccine is still the gold standard of immunomodulating intravesical treatment used to reduce recurrence and progression. Nanotechnology is being developed for the diagnosis and treatment of non-muscle-invasive bladder cancer. The newly developed technology will be able to change intravesical therapy success in non-muscle-invasive bladder cancer

Is adiponectin elevation associated with left atrial remodeling and impaired mechanical functions? (a speckle tracking study)

Objectives Recent studies demonstrated that elevated adiponectin levels predicted an increased risk of atrial fibrillation (AF) and stroke; however, a causal relationship is yet to be unknown. Reduced left atrium (LA) functions detected by two-dimensional echocardiographic speckle tracking (2D-STE) can predict AF development. We aimed to investigate the relationship between adiponectin level and LA functions in hypertensive and diabetic patients at high risk for incident AF. Material and methods The study consisted of 80 hypertensive diabetic patients. All patients underwent echocardiography, and venous blood samples were taken. The relationship between adiponectin levels and LA functions was analyzed. Results We divided patients into two groups according to the mean adiponectin level (13.63 ng/ml). In the high adiponectin group, the mean age (p=0.001) and high-density lipoprotein (HDL) cholesterol (p=0.015) were higher, whereas estimated glomerular filtration rate (eGFR) (p=0.036) and hemoglobin (p=0.014) levels were lower. Although LA maximum volume, LA minimum volume, and LA pre-A volume were higher in the group with high adiponectin levels, they did not reach a statistical significance. Peak early diastolic LA strain (S-LAe) (p=0.048) and strain rate (SR-LAe) (p=0.017) were lower in this group. Multivariate logistic regression analysis demonstrated that age (p=0.003) and hemoglobin (p=0.006) were predictors of elevated adiponectin levels. On the contrary, S-LAe, HDL cholesterol, and eGFR lost their statistical significance. Conclusion In patients with HT and DM, elevated adiponectin level is associated with impaired LA mechanical functions. Increased age and hemoglobin level are independent predictors of elevated adiponectin levels

Competence-oriented course design and monitoring: The approach of Erasmus Plus project “better e-learning for all”

Erasmus Plus Project Better e-Learning for All aims at contributing to the reduction of the gap between the potential value of E-learning and the quality of design of online courses. Departing from research findings in dropout, motivation and retention factors, a conceptual approach to course design was developed and applied to the Better-e MOODLE environment. Better-e platform is designed to support teachers and trainers to overcome uncertainties about pedagogical choices, providing a Competence- oriented decision support environment and a selection of platform features customized to provide easiness of use, to support self-regulation, and to reduce the risks of incurring in common errors of course design that could have a negative impact on retention.The research leading to these results has received funding from the European Community's ERASMUS+ PROGRAMME under grant agreement no. 2015-1-TR01-KA204-021954 “Better e-Learning for All”.info:eu-repo/semantics/acceptedVersio

Change in atrial activation patterns during narrow complex tachycardia: What is the mechanism?

A change in the coronary sinus (CS) activation pattern from an eccentric to a concentric pattern during the ablation of an orthodromic reciprocating tachycardia might falsely suggest the presence of a second (septal) accessory pathway (AP) during tachycardia or the successful ablation of the left lateral AP under ventricular pacing despite persistent and unaffected AP conduction. Complete or partial intra-atrial block should be suspected when an abrupt change in the atrial activation sequence is noted during catheter ablation at the posterolateral and lateral aspects of the mitral annulus. The correct anatomical position of the CS catheter plays a vital role in the differential diagnosis of this situation
