Paraurethral cysts are uncommonly reported in the newborn. Twenty-eight cases have been reported in the English literature until now. These lesions generally resolve spontaneously. For this reason, a conservative approach is recommended, especially in paraurethral cysts of newborn without complications and symptoms. In this paper, we describe a female neonate who had a paraurethral cyst that spontaneously resolved one month after birth and review the literature.
In the present study, morphological, micromorphological, palynological and anatomical characteristics of the genera Opopanax and Crenosciadium are reviewed and compared. The genus Opopanax is distributed in southern Europe, the Mediterranean region and Western Asia, and it is represented by three species in Turkey. Crenosciadium is a poorly known monotypic genus from Turkey, recently treated as synonym in Opopanax. Expanded descriptions, phenology, geographic distributions, and images of habitus of Opopanax and Crenosciadium are given. The differences between the two genera are discussed. The pollen morphology of Opopanax and Crenosciadium is studied by SEM and LM. The palynological results confirmed the stenopalynous characteristic of the family Apiaceae, and revealed that the pollen grains of both genera are perprolate in shape. Also fruit surface ornamentation of both genera is typically striate, and epidermal cells are polygonal or elongated in one direction. Cross-sections of mature fruits are examined and a detailed anatomical description is presented. Mericarp shape and width are very useful characters for discrimination between Opopanax and Crenosciadium; mericarp ribs are also very significant characteristics to discriminate both genera. Our findings, together with previous molecular data, clearly indicate that Crenosciadium differs considerably from Opopanax, and therefore it should be accepted at genus rank.
In this study, the effects of parameters such as substrate hardness, substrate surface roughness and stand-off distance to the coatings formation and properties of the coatings during cold spraying process were examined. For this purpose, coatings were deposited onto the copper substrate with using of commercially available copper powder. Substrate hardness of 55 HV, 107 HV and 140 HV were obtained by heat treatment and deformation hardening methods. Different substrate surface roughness was obtained by using of SiC emery papers which have different grits and stand-off distance during cold spray process was manipulated as 5, 10, 20 and 30 mm. After the production of the coatings, characterisation procedures were performed by microstructural observations which are optical and scanning electron microscope surveys, porosity concentrations, coating thickness and hardness measurement.
A new subspecies Seseli
gummiferum
Pall. ex Sm.
subsp.
ilgazense A.Duran, Ö.Çetin & M.Öztürk, subsp. nov. (Apiaceae) is described from Kastamonu province, Turkey. It was collected from the open Pinus
sylvestris L. and Abies
nordmanniana (Steven) É.Spach. mixed forest in the northern Anatolian region. An endemic apparently confined to the Ilgaz Mountain National Park, the new taxon is closely related to Seseli
gummiferum
subsp.
gummiferum. Diagnostic morphological characters for closely similar taxa are discussed, and a key to the subspecies of Seseli
gummiferum is presented. ITS (Internal Transcribed Spacer) region of the nuclear ribozomal DNA of closely related Seseli L. taxa and Pimpinella is used to constract phylogenetic tree by using BioEdit and Seaview Programme.
A new species, Globularia anatolica A. Duran, Ö. Çetin & M. Öztürk (Globulariaceae) is described and illustrated from southwest Turkey. The species grows on eroded gypsum slopes and in open Pinusbrutia Ten. forest in the Honaz Mountain National Park (C2 Denizli province). It is closely related to G. sintenisii Hausskn. & Wettst., an endemic species confined to southwest Anatolia. Diagnostic morphological characters of Globularia anatolica are discussed and presented as a key to Turkish Globularia. It is suggested that the new species should be regarded as ‘Critically Endangered’ (CR) according to the IUCN criteria. In addition, the biogeography of the Honaz Mountain is briefly outlined.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
