Abstract Genomic copy number aberrations (CNAs) are believed to play a major role in the development and progression of human cancers. Although many CNAs have been reported gastric cancer, their genome‐wide transcriptional consequences poorly understood. In this study, reveal impact on expression we analysed 30 cases cancers for by array comparative genomic hybridization (array CGH) 24 these profiles oligonucleotide‐expression microarray. We found that with application laser microdissection,...
Abstract Australian climate and vegetation, known from marine lacustrine sediments fossils, varied dramatically throughout the Cenozoic Era, with several warm reversals superimposed on overall drying cooling. A suite of landforms, including stony deserts, dunefields playa lakes, formed in response to advancing aridity but their age generally remained uncertain until fairly recently, owing a lack suitable dating methods. Within last 5 years, chronology Late Quaternary fluctuations dunes...
We used Japanese monkeys (Macaca fuscata) to establish an experimental model in order clarify the pathogenicity of Helicobacter pylori gastric and duodenal disorders. A suspension (5 ml; 10(9) CFU/ml) H. cells isolated from humans was sprayed around antrum stomach each 12 17 animals with endoscope. The remaining five were not inoculated; they served as a control group. On days 7, 14, 28 after inoculation, mucosa samples examined grossly biopsied for microscopic examination recovered 7...
Understanding how sediment transport and storage will delay, attenuate, even erase the erosional signal of tectonic climatic forcings has bearing on our ability to read interpret geologic record effectively. Here, we estimate transit times in Australia's largest river system, Murray-Darling basin, by measuring downstream changes cosmogenic 26Al/10Be/14C ratios modern sediment. Results show that sediments have experienced multiple episodes burial reexposure, with cumulative lag exceeding 1 Ma...
Modern fonts adopt vector-based formats, which ensure scalability without loss of quality. While many deep learning studies on focus bitmap for vector remains underexplored. In involving fonts, the choice font representation has often been made conventionally. However, format is one factors that can influence computational performance machine models in font-related tasks. Here we show representations based PostScript outlines outperform those TrueType Transformer-based classification....
Abstract This study investigates surface weathering and sediment preservation at Table Mountain, a high‐elevation, hyperarid, polar landscape in the Transantarctic Mountains. We report cosmogenic nuclide concentrations ( 10 Be 26 Al) quartz from bedrock surfaces, erratic boulder lag, cobbles embedded within Sirius Group sediments to quantify erosion rates. In situ Al depth profiles 2.95 m permafrost core further constrain rates elucidate stability. Measured two sandstone surfaces adjacent...

The widespread use of eradication therapy for Helicobacter pylori in Japan has led to an increase antibiotic-resistant strains and the problem re-treatment cases failure.To perform drug sensitivity testing metronidazole 92 H. pylori-positive patients who had failed treatment with first-line triple therapy, consisting a proton pump inhibitor, amoxicillin clarithromycin, were administered metronidazole-containing second-line therapy.Second-line rabeprazole (20 mg b.d.), (750 b.d.) (250 was 1...
Summary Background : The resistance of Helicobacter pylori to clarithromycin has become one the primary reasons for eradication failure. Aim To compare rates triple therapy using amoxicillin (A), (C) and rabeprazole (R) or lansoprazole (L) against clarithromycin‐sensitive clarithromycin‐resistant strains. Methods Two hundred ninety‐five patients were randomly divided into four groups treated 1 week: 147 cases with RAC, i.e. 49 R20C400 (10 mg R + 750 A 200 C, twice daily), 48 R40C400 (20...

Summary Background Large‐scale studies of rabeprazole‐based Helicobacter pylori eradication therapy have not been reported in Japan. Aims To evaluate H. by with reference to antibiotic susceptibility, CYP2C19 genotype, and rabeprazole clarithromycin dosages. Methods From 35 centres 479 ‐positive patients gastric or duodenal ulcer were randomized four treatment groups: Group 1 (10 mg + 750 amoxicillin 200 twice daily for 7 days); 2 mg, 400 mg); 3 (20 mg) 4 mg). Results Eradication rates 86%...
