First Report of Columbia Root-Knot Nematode (\u3ci\u3eMeloidogyne chitwoodi\u3c/i\u3e) in Potato in Turkey

Columbia root-knot nematode, Meloidogyne chitwoodi Golden et al., was identified from potatoes, Solanum tuberosum L., collected from Nigde Province, Turkey in September 2006. Seed potatoes are the most likely source for this introduction. The nematode is currently found to be infecting potatoes grown in the Netherlands, Portugal, Belgium, Germany, the United States, Mexico, South Africa, and Argentina. M. chitwoodi acquired a quarantine status in Europe (1) because of its potential to become established worldwide and its high damage probability. Some countries prohibit import of both seed and table stock potatoes originating in states known to harbor M. chitwoodi. Lesions on the potatoes had discrete brown coloration with white central spots in the outer 1 cm of the tuber flesh

ToonNote: Improving Communication in Computational Notebooks Using Interactive Data Comics

Computational notebooks help data analysts analyze and visualize datasets, and share analysis procedures and outputs. However, notebooks typically combine code (e.g., Python scripts), notes, and outputs (e.g., tables, graphs). The combination of disparate materials is known to hinder the comprehension of notebooks, making it difficult for analysts to collaborate with other analysts unfamiliar with the dataset. To mitigate this problem, we introduce ToonNote, a JupyterLab extension that enables the conversion of notebooks into “data comics.” ToonNote provides a simplified view of a Jupyter notebook, highlighting the most important results while supporting interactive and free exploration of the dataset. This paper presents the results of a formative study that motivated the system, its implementation, and an evaluation with 12 users, demonstrating the effectiveness of the produced comics. We discuss how our findings inform the future design of interfaces for computational notebooks and features to support diverse collaborators

Application of the bentix index in assessing ecological quality of hard substrata: a case study from the Bosphorus Strait, Turkey

In this paper, a biotic index (Bentix) has been used for the assessment of ecological quality status of shallow water hard substrate benthic ecosystems affected by coastal sewage discharges in the Bosphorus Strait. A significant difference was observed between the control and the discharge stations with regard to Bentix values (Mann-Whitney U Test, p=0.002) and ecological quality status of the discharge stations was worse than that of controls. The index values revealed that sewage discharges caused serious disturbance in macrozoobenthic communities in the area investigated. Although so far it has been used for soft bottom communities, Bentix (with some species scoring modifications) also appeared to work successfully in hard substrates, at least for the present study

On the Occurrence and Established Populations of the Alien Polychaete Polydora cornuta Bosc, 1802 (Polychaeta: Spionidae) in the Sea of Marmara and the Bosphorus Strait (Turkey)

The present paper reports the first occurrence of Polydora cornuta in the Bosphorus Strait and its finding in a new locality in the Sea of Marmara, providing a link with its Aegean and Black Sea populations. The probable vector for the introduction of P. cornuta into the Sea of Marmara is shipping through the Dardanelles Strait. Both soft and hard-bottom populations were examined and the importance and prevalence of this species within the native macrozoobenthic communities were elucidated. Its abundance ranged between 40 and 3390 ind.m-2 (mean:1320 ±1199.45 SD) and its percent contribution to the total faunal populations ranged between 3.31 and 75.56 (mean:27.79 ±25.00 SD) in the Sea of Marmara softbottom community. During the sampling period, P. cornuta contributed little to the total faunal abundance of the hard-bottom communities in the Bosphorus Strait. Its mean abundance in the hard substrate ranged between 8.33 and 1000 ind.m-2 (mean:117.36 ±279.73 SD) and its percent contribution to the total faunal populations ranged between 0.02 and 21.86 (mean:2.07 ±6.25 SD). The role of this invasive species in the soft-bottom macrobenthic community at an organically enriched site examined in the Sea of Marmara is highlighted, and a comparison with Aegean Sea populations of the species is also included

Pressure-tuning of the c-f hybridization in Yb metal detected by infrared spectroscopy up to 18 GPa

It has been known that the elemental Yb, a divalent metal at mbient pressure, becomes a mixed-valent metal under external pressure, with its valence reaching ~2.6 at 30 GPa. In this work, infrared spectroscopy has been used to probe the evolution of microscopic electronic states associated with the valence crossover in Yb at external pressures up to 18 GPa. The measured infrared reflectivity spectrum R(w) of Yb has shown large variations with pressure. In particular, R(w) develops a deep minimum in the mid-infrared, which shifts to lower energy with increasing pressure. The dip is attributed to optical absorption due to a conduction c-f electron hybridization state, similarly to those previously observed for heavy fermion compounds. The red shift of the dip indicates that the $c$-$f$ hybridization decreases with pressure, which is consistent with the increase of valence.Comment: 2 pages, to appear in J. Phys. Soc. Jpn. Supp

Erythropoietin Improves the Healing of Skin Necrosis Resulting From Doxorubicin Extravasation in a Rat Model

AbstractBackgroundDoxorubicin is an antineoplastic agent that causes skin necrosis when extravasated. Various agents have been tried to reduce tissue damage owing to extravasation. Erythropoietin (EPO) is an obligatory growth factor for red blood cells and has beneficial effects on wound healing.ObjectiveThe aim of this study was to test the hypothesis that local EPO injection can prevent and improve healing of necrosis at the doxorubicin injection site in rats.MethodsWe used 31 female Sprague-Dawley rats. The dorsal area of each rat was shaved, and 2 mg of doxorubicin in 0.5 mL saline was injected intradermally. The rats were then divided into 3 groups: control; control with intradermal injection of saline; and treatment, which received an intradermal injection of EPO. EPO in saline was injected into 4 quadrants of the same site where doxorubicin was injected 1 hour before. The rats were monitored and the area of each ulcer was measured. Skin biopsies were excised at the end of 4 weeks using anesthetic pentobarbital. Inflammation, edema, epithelization, neovascularization, necrosis, fibroblast proliferation, and collagen synthesis were evaluated and compared between groups.ResultsThe average areas of the lesions were significantly smaller in the EPO-injected rats (P = 0.03). The histopathologic evaluation revealed that the scores for epithelization, neovascularization, fibroblast proliferation, and collagen synthesis were higher (P < 0.001, P < 0.001, P = 0.002, and P = 0.04, respectively) and the score for necrosis was lower (P < 0.001) in the EPO-injected group than in both the saline-injected and control groups.ConclusionsIn this study using female Sprague-Dawley rats, EPO treatment improved the healing of skin necrosis caused by doxorubicin injection. This finding may lead to a new therapeutic approach for the management of skin necrosis caused by doxorubicin extravasation

Durability of cantilever inlay-retained fixed dental prosthesis fabricated from multilayered zirconia ceramics with different designs.

PURPOSE The purpose of this in-vitro study was to investigate the effect of framework design on fracture resistance and failure modes of cantilever inlay-retained fixed partial dentures (IRFDPs) fabricated from two multilayered monolithic zirconia materials. MATERIALS AND METHODS Seventy-two natural premolar teeth were prepared as abutments for cantilever IRFDPs using three designs: mesial-occlusal (MO) inlay with short buccal and palatal wings (D1), MO inlay with long palatal wing (D2), MO inlay with long palatal wing and occlusal extension (D3). Full-contoured IRFDPs were fabricated from two monolithic zirconia materials; IPS e.max ZirCAD Prime and Zolid Gen-X. Adhesive surfaces were air-abraded and bonded with MDP-containing resin cement. Specimens were subjected to thermocycling (5-55 °C, 5000 cycles); then, mechanical loading (1.2 × 10⁶ cycles, 49 N). Surviving specimens were loaded until failure in the universal testing machine. All specimens were examined under stereomicroscope, and two samples from each group were evaluated using Scanning Electron Microscope. RESULTS Mean failure loads were not significantly different between different framework designs or between two materials. However, IPS e.max ZirCAD Prime showed significantly higher failure rate than Zolid Gen-X during dynamic fatigue (p = 0.009). Samples with D1 design showed higher debonding rate, D2 failed mainly by fracture of the palatal wing and debonding, and D3 failed mainly by fracture of the abutment tooth. Debonded restorations showed mainly mixed failures. CONCLUSION Cantilever IRFDPs with framework designs that maximize adhesion to enamel exhibited promising results. IPS e.max ZirCAD Prime was more susceptible to fractures with the long palatal wing design

Caucasoseris, a new genus of subtribe Chondrillinae (Asteraceae: Cichorieae) for the enigmatic Prenanthes abietina

A new genus, Caucasoseris, is established to accommodate Prenanthes abietina, a species of hitherto uncertain systematic position distributed in the western Caucasus and northeasternmost Turkey in montane conifer and mixed forests. Agreement has existed that the species belongs somewhere in the Crepidinae or Lactucinae but its morphological features do not match any genus and previous molecular phylogenetic analyses could not establish its sister group. This study provides additional micro- and macromorphological, palynological and anatomical data, and used a molecular phylogenetic sampling designed to ascertain its relationship. A sister group relationship with the Chondrillinae is inferred from the phylogenetic tree based on nrITS. In the plastid DNA tree, where the Chondrillinae are resolved as a clade nested inside the Crepidinae, the species is resolved further remote from the Chondrillinae clade and in a rather early diverging position of the Crepidinae. In agreement also with the anatomical and microand macromorphological findings, it is considered an orphan lineage with affinities to the Chondrillinae, best treated as a genus of its own. A key to the genera of the Chondrillinae including Caucasoseris is provided.Peer reviewe
