Identification of medically important yeasts by sequence analysis of the internal transcribed spacer and D1/D2 region of the large ribosomal subunit

AYDIN, Merve | KUŞTİMUR, Semra | KALKANCI, Ayşe | DURAN, Tuğçe

Background: The prevalence of opportunistic yeast infections has increased in recent decades as the resultof an increasing immunocompromised patient population.Aims: To evaluate ribosomal RNA (rRNA) gene sequence to identify medically important yeast species, toinvestigate the performance of both the rRNA gene internal transcribed spacer (ITS) and D1/D2 region in identifying clinically relevant yeasts, and to compare these results with those of a standard phenotypicmethod.Methods: Both regions from 50 yeast strains, comprising 45 clinical isolates and 5 reference strains, wereamplified using P ...Daha fazlası

Methods: The study included urticaria patients and healthy individuals that presented to our polyclinic between June 2015 and May 2017. 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

Charged jet cross section and fragmentation in proton-proton collisions pffiffi at s=7TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Azimuthally-differential femtoscopic measurements, being sensitive to spatio-temporal characteristics of the source as well as to the collective velocity fields at freeze out, provide very important information on the nature and dynamics of the system evolution. While the HBT radii oscillations relative to the second harmonic event plane measured recently reflect mostly the spatial geometry of the source, model studies have shown that the HBT radii oscillations relative to the third harmonic event plane are predominantly defined by the velocity fields. In this Letter, we present the first resu ...Daha fazlası

Measurement of Upsilon(1S) Elliptic Flow at Forward Rapidity in Pb-Pb Collisions at sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The first measurement of the Υð1SÞ elliptic flow coefficient (v2) is performed at forward rapidity (2.5 < y < 4) in Pb–Pb collisions at sNN 1⁄4 5.02 TeV with the ALICE detector at the LHC. The results are obtained with the scalar product method and are reported as a function of transverse momentum (pT ) up to 15 GeV=c in the 5%–60% centrality interval. The measured Upsilon is consistent with 0 and with the small positive values predicted by transport models within uncertainties. The v2 coefficient in 2 < pT < 15 GeV=c is lower than that of inclusive J=ψ mesons in the same pT interval by 2.6 st ...Daha fazlası

Jet fragmentation transverse momentum measurements from di-hadron correlations in √s = 7 TeV pp and √sNN = 5.02 TeV p–Pb collisions

KARASU UYSAL, Ayben | ALICE Collaboration

The transverse structure of jets was studied via jet fragmentation transverse momentum (jT) distributions, obtained using two-particle correlations in proton-proton and proton-lead collisions, measured with the ALICE experiment at the LHC. The highest transverse momentum particle in each event is used as the trigger particle and the region 3 < pTt < 15 GeV/c is explored in this study. The measured distributions show a clear narrow Gaussian component and a wide non-Gaussian one. Based on Pythia simulations, the narrow component can be related to non-perturbative hadronization and the wide compo ...Daha fazlası

Study of J/ψ azimuthal anisotropy at forward rapidity in Pb-Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The second (v2) and third (v3) flow harmonic coefficients of J/ψ mesons are measured at forward rapidity (2.5 < y < 4.0) in Pb-Pb collisions at √sNN = 5.02 TeV with the ALICE detector at the LHC. Results are obtained with the scalar product method and reported as a function of transverse momentum, pT, for various collision centralities. A positive value of J/ψ v3 is observed with 3.7σ significance. The measurements, compared to those of prompt D0 mesons and charged particles at mid-rapidity, indicate an ordering with vn(J/ψ) < vn(D0) < vn(h±) (n = 2, 3) at low and intermediate pT up to 6GeV/c ...Daha fazlası

Two-particle differential transverse momentum and number density correlations in p-Pb collisions at 5.02 TeV and Pb-Pb collisions at 2.76 TeV at the CERN Large Hadron Collider

KARASU UYSAL, Ayben | ALICE Collaboration

We present measurements of two-particle differential number correlation functions R2 and transverse momen- tum correlation functions P2, obtained from p-Pb collisions at 5.02 TeV and Pb-Pb collisions at 2.76 TeV. The results are obtained by using charged particles in the pseudorapidity range |η| < 1.0 and transverse momentum range 0.2 < pT < 2.0 GeV/c as a function of pair separation in pseudorapidity, |η|, azimuthal angle φ, and for several charged-particle multiplicity classes. Measurements are carried out for like-sign and unlike-sign charged-particle pairs separately and combined to obtain ...Daha fazlası

Measurement of the production of charm jets tagged with D0 mesons in pp collisions at √s = 7 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The production of charm jets in proton-proton collisions at a center-of-mass √ energy of s = 7 TeV was measured with the ALICE detector at the CERN Large Hadron Collider. The measurement is based on a data sample corresponding to a total inte- grated luminosity of 6.23nb−1, collected using a minimum-bias trigger. Charm jets are identified by the presence of a D0 meson among their constituents. The D0 mesons are 0−+0 reconstructed from their hadronic decay D →K π . The D -meson tagged jets are reconstructed using tracks of charged particles (track-based jets) with the anti-kT algo- rithm in the ...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

Informal Breast Milk Sharing in a Muslim Country: The Frequency, Practice, Risk Perception, and Risk Reduction Strategies Used by Mothers

ONAT, Güliz | KARAKOÇ, Hediye

Turkey is the first and only Islamic country which has initiated a process to establish a milk bank. However, the effort was abandoned because of religious concerns. Informal breast milk sharing has become a practical alternative to some. Research Aims: To document the religious concerned views and attitudes toward breast milk sharing and to determine risk reduction strategies of mothers in an Islamic country. Materials and Methods: Participants comprised volunteers from relevant forums or members of social media groups on the Internet. The participants (n = 435) were divided into three groups ...Daha fazlası
