Objective: This study aimed to determine the effectiveness of an intratympanic (IT) injection of a mixture of gentamicin and dexamethasone compared with intratympanic dexamethasone (ITD) for controlling vertigo and protecting the hearing level of Meniere's disease patients who have persistent vertigo attacks, despite medical treatment. Methods: Thirty eight patients with intractable Meniere's disease were included in this study. Twenty-one patients were treated with IT mixture gentamicin and dexamethasone injection; seventeen patients were treated with ITD. Pre- and post-treatment audiograms w ...Daha fazlası

The participants were assigned into Group I (137 patients), subdivided into acute (72) and chronic urticaria patients (65), and Group II (129 control individuals). Blastocystis presence was investigated by native-Lugol examination, trichrome staining, ...Daha fazlası

İnsan parechoviruslarının özellikleri, epidemiyolojisi ve klinik önemi

TOKAK, Semih | ÖZDEMİR, Mehmet

İnsan Parechoviruslar (Human Parechovirus; HPeV) tek iplikli, pozitif polariteli RNA viruslarıdır. Başlangıçta klinik ve morfolojik özelliklerine göre insan enterovirusları içerisinde Echovirus 22 ve 23 olarak tanımlansalar da, genom organizasyonu, yapı ve replikasyonlarında birkaç farklı özellikleriyle enteroviruslar ve diğer picornavirus gruplarından farklı oldukları gösterilmiştir. HPeV’ler genetik ve antijenik heterojenlik göstermekte ve birçok tipi dünyanın her yerinde bulunan insan popülasyonunda yaygın bir şekilde bulunmaktadır. HPeV1 en yaygın genotip olup sıklıkla gastrointestinal ve ...Daha fazlası

Comparison of the effects of the temperature of intratympanic dexamethasone injections on vertigo

ATA, Nurdoğan | ÖZTÜRK, Kayhan | GEZGİN, Bahri

Objective: This study aimed to compare if vertigo improved in patients when the dexamethasone used in the intratympanic (IT) injection was applied at body temperature or at room temperature. Methods: The study included 54 patients who had undergone intratympanic treatment due to sudden hearing loss and tinnitus. The IT injection was administered to all patients, 2 times with 1-day intervals. Two different IT injection techniques were used for each patient: injecting dexamethasone at room temperature and injecting it at body temperature. Patients were asked to report the vertigo they felt immed ...Daha fazlası

Absence of the mecC gene in methicillin-resistant Staphylococcusaureus isolated from various clinical samples: The first multi-centeredstudy in Turkey

tBackground: mecA is a predefined gene causing methicillin resistance in Staphylococcus aureus (S. aureus)isolates; however, it has been shown that some methicillin-resistant S. aureus (MRSA) strains do notcarry this gene. Recently, in isolates found to be MRSA-positive but mecA-negative, a new resistance gene called mecC, which is a homolog of mecA, has been reported. This study aimed to investigate the mecCand mecA genes in MRSA strains isolated from different geographic regions in Turkey.Methods: The sample of the study consisted of 494 MRSA strains isolated from seven geographical regionsi ...Daha fazlası

Event-shape and multiplicity dependence of freeze-out radii in pp collisions at √s = 7 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Two-particle correlations in high-energy collision experiments enable the extraction of particle source radii by using the Bose-Einstein enhancement of pion production at low relative momentum q ∝ 1/R. It was previously observed that in pp collisions at √s = 7 TeV the average pair transverse momentum kT range of such analyses is limited due to large background correlations which were attributed to mini-jet phenomena. To investigate this further, an event-shape dependent analysis of Bose-Einstein correlations for pion pairs is performed in this work. By categorizing the events by their transver ...Daha fazlası

Recommendations for calculation of strengthened brick walls with perforated plates

ÖZBEK, Eray | AYKAÇ, Bengi | CAN, Hüsnü | KALKAN, İlker | AYKAÇ, SabahattiN

There are many studies relating to the strengthening of infill brick walls, which contribute partially to the resistance against the seismic forces, by using different methods and materials to make them behave similarly to a ductile RC walled system. Unlike other research, studies using perforated steel plates have improved behavior on ductility as well as strength. Experimental results show that there is no significant loss of strength even at relative floor drift ratios up to 7.5%. The aim of the present study is to generate calculation and modelling approaches for designers who choose this ...Daha fazlası

Measurement of the inclusive isolated photon production cross section in pp collisions at √s = 7 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The production cross section of inclusive iso- lated photons has been measured by the ALICE experiment at the CERN LHC in pp collisions at a centre-of-momentum energy of √s = 7 TeV. The measurement is performed with the electromagnetic calorimeter EMCal and the central track- ing detectors, covering a range of |η| < 0.27 in pseudora- pidity and a transverse momentum range of 10 < pTγ < 60 GeV/c. The result extends the pT coverage of previously published results of the ATLAS and CMS experiments at the same collision energy to smaller pT. The measurement is compared to next-to-leading order pert ...Daha fazlası

A Hybrid Model For The Prediction Of Aluminum Foil Output Thickness İn Cold Rolling Process

ÖZTÜRK, Ali | ŞEHERLİ, Rıfat

This study proposes a hybrid model composed of multiple prediction algorithms and an autoregressive moving average (ARMA) module for the thickness prediction. In order to attain higher accuracy, the prediction algorithms were globally combined by simple voting to reduce the effect of the inductive bias imposed by each algorithm on the dataset. The global multiexpert combination (GMEC) system included the multilayer perceptron neural network (MLPNN), radial basis function network (RBFN), multiple linear regression (MLR), and support vector machines (SVM) algorithms. The proposed hybrid model ex ...Daha fazlası

Borrelia burgdorferi chemotaxis toward tick protein Salp12 contributes to acquisition

MURFIN, Kristen E. | KELINBARD, Ruby | AYDIN, Merve | SALAZAR, Samuel A. | FIKRIG, Erol

Lyme disease is a common tick-borne infection caused by the spirochete Borrelia burgdorferi sensu stricto (s.s.). B. burgdorferi s.s. may utilize chemotaxis, the directional migration towards or away from a chemical stimulus, for transmission, acquisition, and infection. However, the specific signals recognized by the spirochete for these events have not been defined. In this study, we identify an Ixodes scapularis salivary gland protein, Salp12, that is a chemoattractant for the spirochete. We demonstrate that Salp12 is expressed in the I. scapularis salivary glands and midgut and expression ...Daha fazlası
