1Phylogenomic delineation of Physcomitrium (Bryophyta: Funariaceae) based on targeted sequencing of nuclear exons and their flanking regions rejects the retention of Physcomitrella, Physcomitridium and Aphanorrhegma显示文摘Selection on spore dispersal mechanisms in mosses is thought to shape the transformation of the sporophyte. The majority of extant mosses develop a sporangium that dehisces through the loss of an operculum, and regulates spore release through the movement of articulate teeth, the peristome, lining the capsule mouth. Such complexity was acquired by the Mesozoic Era, but was lost in some groups during subsequent diversification events, challenging the resolution of the affinities for taxa with reduced architectures. The Funariaceae are a cosmopolitan and diverse lineage of mostly annual mosses, and exhibit variable sporophyte complexities, spanning from long, exerted, operculate capsules with two rings of well‐developed teeth, to capsules immersed among maternal leaves, lacking a differentiated line of dehiscence (i.e., inoperculate) and without peristomes. The family underwent a rapid diversification, and the relationships of taxa with reduced sporophytes remain ambiguous. Here, we infer the relationships of five taxa with highly reduced sporophytes based on 648 nuclear loci (exons complemented by their flanking regions), based on inferences from concatenated data and concordance analysis of single gene trees. Physcomitrellopsis is resolved as nested within one clade of Entosthodon. Physcomitrella s. l., is resolved as a polyphyletic assemblage and, along with its putative relative Aphanorrhegma, nested within Physcomitrium. We propose a new monophyletic delineation of Physcomitrium, which accommodates species of Physcomitrella and Aphanorrhegma. The monophyly of Physcomitrium s. l. is supported by a small plurality of exons, but a majority of trees inferred from exons and their adjacent non‐coding regions.Rafael Medina Matthew G.

2对外汉语文化教学内容划分研究述评显示文摘中国对外汉语教学界30年来对对外汉语文化教学的研究如火如荼,对其作了全方位的探究,文化教学内容的划分就是其中占有重要地位并获得广泛关注的一个研究领域。但到目前为止,学界对文化教学内容划分的研究尚存有诸多争议,由此也制约了与之相关领域研究的步伐。本文拟从交际文化在文化内容划分中的凸显、文化教学内容具体划分和文化教学内容层次安排三个方面对其进行回顾和述评,以期对后来学者的继续研究有所裨益。李修斌 Matthew JOHNSON 2013海外华文教育2013,,2:3
3Celiac disease:Management of persistent symptoms in patients on a gluten-free diet显示文摘AIM:To investigate all patients referred to our center with non-responsive celiac disease (NRCD),to establish a cause for their continued symptoms.METHODS:We assessed all patients referred to our center with non-responsive celiac disease over an 18-mo period.These individuals were investigated to establish the eitiology of their continued symptoms.The patients were first seen in clinic where a thorough history and examination were performed with routine blood work including tissue transglutaminase antibody measurement.They were also referred to a specialist gastroenterology dietician to try to identift any lapses in the diet and sources of hidden gluten ingestion.A repeat small intestinal biopsy was also performed and compared to biopsies from the referring hospital where possible.Colonoscopy,lactulose hydrogen breath testing,pancreolauryl testing and computed tomography scan of the abdomen were undertaken if the symptoms persisted.Their clinical progress was followed over a minimum of 2 years.RESULTS:One hundred and twelve consecutive patients were referred with NRCD.Twelve were found not to have celiac disease (CD).Of the remaining 100 patients,45% were not adequately adhering to a strict gluten-free diet,with 24 (53%) found to be inadvertently ingesting gluten,and 21 (47%) admitting noncompliance.Microscopic colitis was diagnosed in 12% and small bowel bacterial overgrowth in 9%.Refractory CD was diagnosed in 9%.Three of these were diagnosed with intestinal lymphoma.After 2 years,78 patients remained well,eight had continuing symptoms,and four had died.CONCLUSION:In individuals with NRCD,a remediable cause can be found in 90%:with continued gluten ingestion as the leading cause.We propose an algorithm for investigation.David H Dewar Suzanne C Donnelly Simon D McLaughlin Matthew W Johnson H Julia Ellis Paul J Ciclitira 2012World Journal of Gastroenterology2012,18,12:2
