| 1 | Relationship between the severity of hepatitis C virus-related liver disease and the presence of Helicobacter species in the liver: A prospective study显示文摘AIM: To determine the presence of Helicobacter species DNA in the liver of chronic hepatitis C (CHC) patients with and without cirrhosis as compared to controls, and to identify the bacterial species involved. METHODS: Seventy-nine consecutive patients (HBV and HIV negative) with a liver sample obtained after liver biopsy or hepatic resection were studied: 41 with CHC without cirrhosis, 12 with CHC and cirrhosis, and 26 controls (HCV negative). Polymerase chain reactions (PCRs) targeting Helicobacter 16S rDNA and species- specific were performed on DNA extracted from the liver. A gastric infection with H pylori was determined by serology and confirmed by 13C-urea breath test. RESULTS: Overall, Helicobacter 16S rDNA was found in 16 patients (20.2%). Although positive cases tended to be higher in CHC patients with cirrhosis (41.6%) than in those without cirrhosis (17.0%) or in controls (15.4%), the difference was not statistically significant (P =0.08). H pylori-like DNA was identified in 12 cases and H. pullorum DNA in 2, while 2 cases remained unidenti- fied. Gastric infection with H pylori was found in only 2 of these patients. CONCLUSION: Our results do not confirm the associ- ation of Helicobacter species DNA in the liver of CHC patients with advanced liver disease. The lack of correlation between positive H pylori serology and the presence of H pylori-like DNA in the liver may indicate the presence of a variant of this species. | Laurent Castéra Anne Pedeboscq Marcia Rocha Brigitte Le Bail Corinne Asencio Victor de Lédinghen Pierre-Henri Bernard Christophe Laurent Marie-Edith Lafon Maylis Capdepont Patrice Couzigou Paulette Bioulac-Sage Charles Balabaud FrancisMégraud Armelle Ménard | 2006 | World Journal of Gastroenterology2006，12，45： | 3 |
| 2 | A framework infrageneric classification of Carex (Cyperaceae) and its organizing principles显示文摘Phylogenetic studies of Carex L.(Cyperaceae)have consistently demonstrated that most subgenera and sections are para-or polyphyletic.Yet,taxonomists continue to use subgenera and sections in Carex classification.Why?The Global Carex Group(GCG)here takes the position that the historical and continued use of subgenera and sections serves to(i)organize our understanding of lineages in Carex,(ii)create an identification mechanism to break the~2000 species of Carex into manageable groups and stimulate its study,and(iii)provide a framework to recognize morphologically diagnosable lineages within Carex.Unfortunately,the current understanding of phylogenetic relationships in Carex is not yet sufficient for a global reclassification of the genus within a Linnean infrageneric(sectional)framework.Rather than leaving Carex classification in its current state,which is misleading and confusing,we here take the intermediate steps of implementing the recently revised subgeneric classification and using a combination of informally named clades and formally named sections to reflect the current state of our knowledge.This hybrid classification framework is presented in an order corresponding to a linear arrangement of the clades on a ladderized phylogeny,largely based on the recent phylogenies published by the GCG.It organizes Carex into six subgenera,which are,in turn,subdivided into 62 formally named Linnean sections plus 49 informal groups.This framework will serve as a roadmap for research on Carex phylogeny,enabling further development of a complete reclassification by presenting relevant morphological and geographical information on clades where possible and standardizing the use of formal sectional names. | Eric H.Roalson Pedro Jiménez-Mejías Andrew L.Hipp Carmen Benítez-Benítez Leo P.Bruederle Kyong-Sook Chung Marcial Escudero Bruce A.Ford Kerry Ford Sebastian Gebauer Berit Gehrke Marlene Hahn Muhammad Qasim Hayat Mathias H.Hoffmann Xiao-Feng Jin Sangtae Kim Isabel Larridon Étienne Léveillé-Bourret Yi-Fei Lu Modesto Luceño Enrique Maguilla Jose IgnacioMárquez-Corro Santiago Martín-Bravo Tomomi Masaki Mónica Míguez Robert F.C.Naczi Anton A.Reznicek Daniel Spalink Julian R.Starr Uzma Tamara Villaverde Marcia J.Waterway Karen L.Wilson and Shu-Ren Zhang | 2021 | Journal of Systematics and Evolution2021，59，4： | 3 |
