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

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

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

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

This study aimed to examine the affects of 3’-4’-dihydroxyflavonol (DiOHF) on lipid peroxidation in experimental renal ischemia-reperfusion. The research was conducted on Wistar-albino type male rat. The experimental groups were formed as 1.Control; 2.Sham; 3.Ischemia; 4.Ischemia+reperfusion; 5.DiOHF+Ischemia; 6.Ischemia+ DiOHF + reperfusion. The highest tissue glutathione levels were found in groups 5 and 6. Groups 1 and 2, which were control and sham groups respectively, had the lowest tissue GSH values. Ischemia group was found to have the highest tissue malondialdehyde (MDA) level. Tissue ...Daha fazlası

Could interleukin-33 and its suppressor of tumorigenicity 2 (ST2) receptor have a role in cervical human papillomavirus (HPV) infections?

KULHAN, Nur Gözde | KULHAN, Mehmet | AYDIN, Merve | NAYKİ, Ümit | NAYKİ, Cenk | ULUĞ, Paşa | ATA, Nahit | MERTOĞLU, Cuma | ÇIKMAN, Aytekin | SAYAR, İlyas | TÜRKLER, Can

Why most women can clear human papillomavirus (HPV) infections while others can develop permanent infections. The stimulation of immunotolerance of the immune system of the host by the persistent HPV infection may be the answer to this question. Interleukin-33 (IL-33) may play a role in the pathogenesis of HPV infection, this hypothesis was thought to be due to the rapid release of IL-33 from damaged cells following tissue damage, necrosis, and activation of the inflammasome. Thus, in this study, the role of IL33/suppressor of tumorigenicity 2 (ST2) was emphasized in HPV positive and HPV negat ...Daha fazlası

Parametric investigation for discrete optimal design of a cantilever retaining wall

URAY, Esra | ÇARBAŞ, Serdar | ERKAN, İbrahim Hakkı | TAN, Özcan

In this paper, discrete design optimization of a cantilever retaining wall has been submitted associated with a detailed parametric study of the wall. In optimal design, the minimum wall weight is treated as the objective function. Through design algorithm, the optimal design variables (base width, toe width, thickness of base slab and angle of front face) yielded minimum structural weight of the wall and satisfied stability conditions have been determined for different soil parameter values. At the end, a detail parametric study searching the effect of change of soil parameters on the retaini ...Daha fazlası
