No full textAmaç: Bu çalışmada, Türkiye’de Sarıkamış/Kars yöresindeki doğal parkta, serbest dolaşımda bulunan boz ayılarda Batı Nil virüsünün (BNV) varlığı/oranı serolojik ve virolojik olarak araştırıldı. Gereç ve Yöntem: Bu amaçla 11 adet boz ayıdan alınan kan örneklerinde BNV spesifik antikor varlığı commercial competitive enzyme-linked immunosorbent assay (C-ELISA) yöntemi ile tarandı. Toplanan kan örneklerinden elde lökosit örneklerinde BNV nükleik asidinin belirlenmesi amacıyla da Reverse Transkripsiyon-Polimeraz Zincir Reaksiyonu (RTPZR) tekniği kullanıldı. Bulgular: Örneklerin hiçbirinde BNV nükleik asidi ve BNV spesifik antikoru tespit edilmedi. Öneri: Türkiye’de serbest dolaşımdaki vahşi memeli hayvanlar ve boz ayılarda varlığı/oranı bilinmeyen BNV enfeksiyonunun ileriki dönemlerde daha ayrıntılı araştırılması gerektiği düşünülmektedir. Bu araştırma Türkiye’de serbest dolaşımdaki boz ayılarda BNV enfeksiyonu ile ilgili yapılan ilk çalışmadır.Aim: This study is a serological and virological examination of the West Nile Virus (WNV) in free-ranging brown bears (Ursus arctos) in Sarikamis district of Kars province of Turkey. Materials and Methods: For this purpose, blood samples from 11 brown bears were tested for antibodies against WNV using a commercial competitive enzyme-linked immunosorbent assay (C-ELISA). Reverse transcription polymerase chain reaction (RT-PCR) technique was used to determine the presence of West Nile Virus nucleic acid. Results: Seropositivity rate was detected to be zero % and West Nile virus nucleic acid was not found in samples. Conclusion: The significance of WNV infection in brown bears and other free-ranging mammals in the Turkey is unknown at this time and will require further investigation. This is the first report of WNV infection in brown bears in Turkey
ISOLATION OF ANTIOXIDATIVE COMPONENTS FROM BOZ PISTACHIO
No full textZa določanje vsebnosti olj v boz pistaciji smo uporabili ekstrakcijo po Soxhletu s topilom heksan in ekstrakcije s superkritičnim fluidom – CO2 pri tlakih od 100 do 300 bar pri temperaturah 35, 45 in 55 °C. Ugotovili smo, da ima pistacija visoko vsebnost olj, in sicer približno 55 %.
S pomočjo konvencionalnih ekstrakcij z različnimi topili (aceton, etanol, 50% aceton, 50 % etanol in destilirana voda) pri sobni temperaturi in pri 40 °C smo določili vsebnost antioksidativnih komponent z UV-metodami za sveže zmleto boz pistacijo in pistacijo po superkritični ekstrakciji pri 200 bar in 35 °C. Dobljenim ekstraktom smo določili vsebnost skupnih fenolov, skupnih flavonoidov, taninov in proantocianidinov s spektrofotometričnimi metodami. Raztopinam ekstraktov smo merili absorbance pri valovnih dolžinah glede na zahteve posamezne metode. Na podlagi znanih koncentracij raztopin standardov in pripadajočih absorbanc smo izdelali umeritveno krivuljo, ki je osnova za določitev vsebnosti posameznih antioksidativnih komponent. Vsebnosti smo podali kot miligram (mg) antioksidativne komponente na gram (g) suhega materiala.
Antioksidativno učinkovitost ekstraktov smo določili z uporabo beta-karotenske metode in DPPH metode. Rezultati analiz vsebnosti antioksidativnih komponent so pokazali, da je boz pistacija dober vir antioksidantov, saj jih vsebuje približno 60 %.For determining the oil content in the boz pistachios we used Soxhlet extraction with solvent hexane and supercritical fluid extraction (SCFE) – CO2 at pressures from 100 to 300 bar and at 35, 45 and 55 °C. We found out that pistachios have high oil content, about 55 %.
Using conventional extraction with various solvents (acetone, ethanol, 50 % acetone, 50 % ethanol and distilled water) at room temperature and 40 °C, we examined the content of antioxidative components with UV methods for fresh ground pistachios and for previously treated material with SCFE at 200 bar and 35 °C. To obtain extracts we determined content of total phenols, total flavonoids, tannins and proanthocyanidins with spectrophotometric method. We measured absorbance to extract solutions at a wavelength depending on the requirements of method. On the basis of known concentrations of standard solutions and the corresponding absorbances we made a calibration curve, which is the basis for the determination of individual antioxidative components. Concentrations were presented in milligrams (mg) of antioxidant components per gram (g) of dry material.
Antioxidant efficacy of extracts was determined using a beta-carotenic and DPPH method. The results of analyzes of antioxidant components have shown that boz pistachio is a good source of antioxidants because it contains approximately 60 % antioxidative components
The "Illimitable Dominion" of Charles Dickens: Transatlantic Print Culture and the Spring of 1842
No full textThis article explores Edgar Allan Poe’s May 1842 edition of Graham’s Monthly Magazine in the context of debates about international copyright circulating in the press at the time of Charles Dickens’s famous tour of the US. I offer a reading of Poe’s short story ‘The Masque of the Red Death’, and his review of Hawthorne’s Twice-Told Tales that sees these texts as interventions in transatlantic debates at the forefront of the public imagination in the Spring of 1842. In particular, through an original close reading of ‘The Masque of the Red Death’ I demonstrate how Poe subtly drew upon penny press exposés to inform the short story’s discussion of class, status and rights of access. I also suggest that the argument Poe made in his review of Nathaniel Hawthorne about the importance of ‘invention, creation, imagination [and] originality’ to the ‘prose tale’ is usefully considered in the same context, as an American response to questions of authorship that were also raised by the popular hysteria surrounding Dickens

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
