Acute kidney injury is common in patients with liver disease and associated with significant morbidity and mortality. Besides bacterial infections, fluid loss, and use of nephrotoxic drugs AKI in liver disease may be triggered by tubular toxicity of cholephiles. Cholemic nephropathy, also known as bile cast nephropathy, supposedly represents a widely underestimated but important cause of renal dysfunction in cholestasic or advanced liver diseases with jaundice. Cholemic nephropathy describes impaired renal function along with characteristic histomorphological changes consisting of intratubular cast formation and tubular epithelial cell injury directed towards distal nephron segments. The underlying pathophysiologic mechanisms are not entirely understood and clear defined diagnostic criteria are still missing.This review aims to summarize (i) the present knowledge on clinical and morphological characteristics of cholemic nephropathy, (ii) available preclinical models, (iii) potential pathomechanisms especially the potential role of bile acids, and (iv) future diagnostic and therapeutic strategies for cholemic nephropathy. This article is part of a Special Issue entitled: Cholangiocytes in Health and Disease edited by Jesus Banales, Marco Marzioni, Nicholas LaRusso and Peter Jansen.  相似文献

Amiloride-sensitive epithelial Na(+) channels (ENaCs) can be formed by different combinations of four homologous subunits, named α, β, γ, and δ. In addition to providing an apical entry pathway for transepithelial Na(+) reabsorption in tight epithelia such as the kidney distal tubule and collecting duct, ENaCs are also expressed in nonepithelial cells, where they may play different functional roles. The δ-subunit of ENaC was originally identified in humans and is able to form amiloride-sensitive Na(+) channels alone or in combination with β and γ, generally resembling the canonical kidney ENaC formed by α, β, and γ. However, δ differs from α in its tissue distribution and channel properties. Despite the low sequence conservation between α and δ (37% identity), their similar functional characteristics provide an excellent model for exploring structural correlates of specific ENaC biophysical and pharmacological properties. Moreover, the study of cellular mechanisms modulating the activity of different ENaC subunit combinations provides an opportunity to gain insight into the regulation of the channel. In this review, we examine the evolution of ENaC genes, channel subunit composition, the distinct functional and pharmacological features that δ confers to ENaC, and how this can be exploited to better understand this ion channel. Finally, we briefly consider possible functional roles of the ENaC δ-subunit.  相似文献

The formula for calculation of the basic homotoneity-coefficient of sets of phytosociological relevés does not give adequate values for sets of 4 or 3 relevés. Therefore an empirical correction procedure is proposed for the calculation of this coefficient for such small sets of relevés. For sets of 2 relevés the calculation of the basic homotoneity-coefficient gives values equal toSørensen’s coefficient of floristic similarity. A simplification of calculation of the basic homotoneity-coefficient for sets of more than 20 relevés is proposed.  相似文献

Names of species and subspecies fromJanchen's Catalogus were revised with regard to their validity; invalidly published names were compiled in a commented list of 120 names. About sixty of them were analyzed at length from nomenclatural and taxonomical viewpoints. The cause of the invalidity of these names were discussed; omission of citations of basionyms to proposals of new nomenclatural combinations is the main reason for the invalidity ofJanchen's names. Taxonomic reclassifications and nomenclatural revisions resulted in 23 new nomenclatural combinations, five of these proposals representing direct validations ofJanchen's invalidly published names. Some more general problems of nomenclature are discussed: indirect validation of invalidly published names; omission of infraspecific homonymy; the correctness and necessity to attach neglected authors' names to the names of plants based on those names distinctly taken over from such authors; problems of autonyms in the ICBN Code. The use of the category “convarietas” in cultivated plants (instead of subspecies) is emphasized. Names validated byJanchen himself in his paper of 1959 should be used with this publication place instead of their invalid publication in the Catalogus. Some propositions for future research by other authors are also added.  相似文献

(A.) silvaticus Zhantiev, 1976 is recorded for the first time from mainland Italy (Apulia); Anthrenus (Anthrenus) angustefasciatus Ganglbauer, 1904 is new to northern Italy (Friuli-Venezia Giulia), central Italy (Tuscany), Apulia and Basilicata; A. (A.) munroi Hinton, 1943 is new to central Italy (Elba Island); A. (A.) delicatus Kiesenwetter, 1851 is for the first time recorded from Apulia; Globicornis (Globicornis) fasciata (Fairmaire & Brisout de Barneville, 1859) is new to southern Italy (Basilicata); G.

Brisout de Barneville, 1866) is for the first time recorded from central Italy (Abruzzi), Campania and Sicily, whileTrogoderma inclusum LeConte, 1854 is new to Apulia.Seven species (Dermestes (Dermestes) peruvianus Laporte de Castelnau, 1840, D. (Dermestinus) carnivorus Fabricius, 1775, D. (Dermestinus) hankae Háva, 1999, D. (Dermestinus) intermedius intermedius Kalík, 1951, D.

ABSTRACT

A critical review of Alba and Foner's Strangers No More (2015 Foner, Nancy. 2015. “Is Islam in Western Europe Like Race in the United States?” Sociological Forum 30 (4): 885–899. [Google Scholar]) which focuses on questioning their comparative assimilation of European cases of immigrant integration to the North American, specifically U.S., experience. While this may work in terms of how national immigrant integration has mitigated over time racial discrimination for older, post-colonial migrants, it misrepresents the complex differentiations involved in the super-diversity of recent ‘new’ migrations within and to Europe. In particular, the variety of types and origins of recent migration is lost in their understanding of the U.K. case, with problems linked to their interpretation of data about minorities and foreigners in the country.  相似文献

One hundred and thirty-nine taxa of mosses are reported from the montane forest zone of southwest Ethiopia. Of these, 53 taxa are new country records and Meteoriopsis reclinata (Müll.Hal.) M.Fleisch. ex Broth. is, in addition, new to Africa. Most of the new records are of species also found in Uganda, Kenya or Tanzania, but there are some surprises, such as Fabronia perciliata Müll.Hal. with the closest location in South Africa and Namibia, Entodontella cameruniae Broth. previously known only from West Africa and Bryomaltaea obtusifolia (Hook.) Goffinet, otherwise reported only from the Democratic Republic of the Congo. We list all taxa and give a short account of their frequency and in which habitat and on which substrate they grow. That such a large proportion of the species are new to the country suggests that Ethiopia is bryologically very under-explored, and that further exploration will reveal many additional species. In particular, the remnant forests of southwest Ethiopia are likely to be of great importance as bryophyte hotspots.  相似文献

The speciesOstorhinchus fleurieu Lacepède, 1802 is recognized as a senior synonym ofApogon aureus (Lacepède, 1802) on the basis of diagnostic colour features of Lacepède’s illustration of the species (after Commerson). The species is redescribed and a neotype designated. The synonymy of the species is discussed in the light of the history of Commerson’s and Lacepède’s work.Nectamia is replaced byOstorhinchus as a subgenus ofApogon.  相似文献
