The phylogeographic structure of the brown hare (Lepus europaeus) was studied by analysing mtDNA control region sequences of 98 individuals from continental and insular Greece, Bulgaria, Cyprus and northern Israel, together with 44 published sequences from Italy and central Europe. We found two distinct clades separated by an average nucleotide divergence(More)
The phylogenetic relationships among species of the Labeobarbus genus (Teleostei, Cyprinidae) which comprises large body-sized hexaploid taxa were inferred using complete cytochrome b mitochondrial gene sequences. Molecular data suggest two main evolutionary groups which roughly correspond to a Northern (Middle East and Northwest Africa) and a sub-Saharan(More)
BACKGROUND The aim of this study was to retrospectively evaluate the short-and long-term effectiveness of different methods of endoscopic treatment for bleeding Dieulafoy's lesions. METHODS Patients were allocated into 2 groups according to the hemostatic method applied: (1) injection group (epinephrine and/or ethanolamine oleate), and (2) thermal(More)
In this study we used genetic approaches to assess the influence of landscape features on the dispersal patterns and genetic structure of two newt species (Triturus macedonicus and Lissotriton vulgaris) living syntopically in a network of ponds. Multilocus genotypes were used to detect and measure genetic variation patterns, population genetic structure and(More)
Cyrtopodion kotschyi is a small gecko, widely distributed on the islands of the Aegean archipelago and the adjacent mainland. We unveiled the phylogeography of the species by using a portion of the cytochrome oxidase I mitochondrial DNA gene from 35 insular and mainland populations. The distinct geographic distribution of the major clades of the(More)
UNLABELLED In this study, our objective was to examine prospectively, by endoscopy and histology of the esophageal mucosa, the severity of reflux esophagitis and any possible correlation between endoscopic and histological findings on the one hand, and manometric and 24-h ambulatory pH-metry measurements on the other. Forty-two patients with(More)
A case of colonic varices manifesting with rectal bleeding in a young patient is presented. There was no evidence of portal hypertension or any other cause. Familial history was also negative. Diagnosis was established by barium enema, colonoscopy and angiography. On colonoscopy, varices involved the entire colon. At operation, dilatation of the subserosal(More)
Thirty-five patients with gastroesophageal reflux (GER) proved on ambulatory esophageal hydrogen monitoring were surgically treated by a floppy Nissen fundoplication. Postoperatively, reflux and symptoms related to it were almost completely abolished. Transient bloating syndrome was observed in five instances. The operation significantly improved(More)
Eleven microsatellite loci were developed in the European anchovy, Engraulis encrasicolus, and tested in samples from two geographically distant populations (Atlantic and Mediterranean Sea). Number of alleles ranged from eight to 28 and observed heterozygosity from 0.440 to 0.920. There was no evidence of linkage disequilibrium, although two loci are indeed(More)
A common source of disturbance for coastal aquatic habitats is nutrient enrichment through anthropogenic activities. Although the water column bacterioplankton communities in these environments have been characterized in some cases, changes in α-diversity and/or the abundances of specific taxonomic groups across enriched habitats remain unclear. Here, we(More)
