Öğe An anatomical study of Scilla (Scilloideae) section Chionodoxa and Scilla bifolia in Turkey [Um estudo anatômico de Chionodoxa incluída na Scilla (Scilloideae) e Scilla bifolia na Turquia](Sociedade Brasileira da Ciencia das Plantas Daninha, 2017) Yildirim H.; Yetisen K.; Özdemir A.; Özdemir C.In the present study Scilla luciliae, S. forbesii, S. sardensis, S. siehei, Scilla x allenii and S. bifolia are compared anatomically. Some differences have been found in root, scape, and leaf anatomy of the taxa, and commented. S. luciliae, S. forbesii, S. sardensis and S. siehei have a metaxylem at the center of the root, others have 3-4 number metaxylem. Vascular bundles in two row in S. luciliae and S. forbesii in a single row in S. sardensis, Scilla x allenii and S. bifolia though in three rows in S. siehei. Aerenchyma tissue is present in mesophyll of five taxa leaf except S. sardensis. The anatomical variations in the taxa have been investigated by means of numerical methods (Analysis of variance and Pearson correlation). By the analysis of the investigated taxa from 12 anatomy related characters, it has been also found that the results from numerical analysis of anatomy characters can provide additional evidences, which correspond to the anatomy for the recognition of the taxa. © 2017, Sociedade Brasileira da Ciencia das Plantas Daninha.

There are not enough data to support for the best approach to diagnosis of HSFI in children, nor for the best treatment.Procedure:In this multicentric study, we assessed the demographic data, clinical and radiologic features, treatment, and outcome of 40 children with leukemia and HSFI from 12 centers.Results:All cases were radiologically diagnosed with abdominal ultrasound, which was performed at a median of 7 days, of the febrile neutropenic episode. Mucor was identified by histopathology in 1, and Candida was identified in blood cultures in 8 patients. Twenty-two had fungal infection in additional sites, mostly lungs. Nine patients died. Four received a single agent, and 36 a combination of antifungals.Conclusions:Early diagnosis of HSFI is challenging because signs and symptoms are usually nonspecific. In neutropenic children, persistent fever, back pain extending to the shoulder, widespread muscle pain, and increased serum galactomannan levels should alert clinicians. Abdominal imaging, particularly an abdominal ultrasound, which is easy to perform and available even in most resource-limited countries, should be recommended in children with prolonged neutropenic fever, even in the absence of localizing signs and symptoms. © 2018 Wolters Kluwer Health, Inc.

Cross-sections of the root, stem, corm and leaf parts of C. flavus subsp. flavus were examined and cross-sections of the root, stem and leaf demonstrated by illustrations. The corm-tunic is membranous, splitting into vertical fibres and lacking distinct horizontal rings at the base. The style is obscurely trilobed or slightly divided. These features are characteristic of C. flavus subsp. flavus. Differences such as shape of leaf keel and branching of style were determined by comparing the results obtained from this subspecies with the results obtained from the other subspecies Crocus flavus Weston subsp. dissectus and species of Iridaceae in previous studies. © TÜBİTAK.
