Many Helicobacter pylori isolates contain a 40-kb region of chromosomal DNA known as the cag pathogenicity island (PAI). The risk for development of gastric cancer or peptic ulcer disease is higher among humans infected with cag PAI-positive H. pylori strains than among those infected with cag PAI-negative strains. The cag PAI encodes a type IV secretion system that translocates CagA into gastr...
We have analysed the CAG repeat in the Huntington disease (HD) gene in sperm and blood from 20 unrelated HD patients. Although the CAG repeat displayed significant mosaicism in sperm from all individuals, there were marked differences in the degree of repeat instability. Individuals who had either inherited or transmitted an expanded CAG repeat displayed the highest levels of repeat mosaicism, ...
Helicobacter pylori strains harboring the cag pathogenicity island (PAI) have been associated with more severe gastric disease in infected humans. The cag PAI encodes a type IV secretion (T4S) system required for CagA translocation into host cells as well as induction of proinflammatory cytokines, such as interleukin-8 (IL-8). cag PAI genes sharing sequence similarity with T4S components from o...
Chronic atrophic gastritis (CAG) is a very common gastritis and one of the major precursor lesions of gastric cancer, one of the most common cancers worldwide. The molecular mechanism underlying CAG is unclear, but its elucidation is essential for the prevention and early detection of gastric cancer and appropriate intervention. A combination of two-dimensional gel electrophoresis and mass spec...
مقدمه: سودوموناس آئروژینوزا یکی از پاتوژن های فرصت طلب بیمارستانی است که در بیماران سوختگی، تنفسی، افراد مبتلا به بیماری وراثتی فیبروز سیستیک، باکتریمی، سپتی سمی و خیلی از عفونت های شایع دیگر دخیل می باشد. سودوموناس آئروژینوزا دارای دو نوع papi حلقوی شامل 1 papi- (108kb) و papi-2 (11kb) می باشد. جزیره بزرگ یعنی papi-1 نقش مهم و کلیدی تری در ویرولانس، تکامل و گسترش روند بیماری زایی باکتری دارد و...
The cag pathogenicity island (cag-PAI) is one of the major virulence determinants of Helicobacter pylori. The chromosomal integrity of this island or the lack thereof is speculated to play an important role in the progress of the gastroduodenal pathology caused by H. pylori. We determined the integrity of the cag-PAI by using specific flanking and internally anchored PCR primers to know the bio...
چکیده: درحماسه ها و اسطوره ها، قهرمان به معنی کسی است که ویژگی هایی نیک، همراه با اعمال پهلوانی دارد و در داستان، شخصیّت مرکزی است که می تواند شخصی خوب یا بد باشد. دوران حماسه سرایی سر آمده است و قهرمانان داستان ها، مطلق و عاری از عیب نیستند. امّا کهن الگوهای اسطوره ای، که کهن-الگوی قهرمان یکی از آن هاست، در داستان های معاصر وجود دارند و سختی هایی که قهرمان رمان از سر می گذراند، پیشتر در ماجراج...
Abstract Chronic atrophic gastritis (CAG) is well-known related with multiple pathogenic factors and normally therapies comprised by western or Chinese medicines. The present study was designed to identify the bacterial community characterized 16S rRNA amplicon sequencing determine modulate affection of composition response medicine Qinghuayin (QHY) as well antibiotic on model rats. result show...
Huntington disease (HD) is caused by an expanded HTT CAG repeat that leads in a length-dependent, completely dominant manner to onset of a characteristic movement disorder. HD also displays early mortality, so we tested whether the expanded CAG repeat exerts a dominant influence on age at death and on the duration of clinical disease. We found that, as with clinical onset, HD age at death is de...
AIM To investigate the bactericidal effects of calcium chelated N-acetylneuraminic acid-glycomacropeptide (CaG-NANA) against Helicobacter pylori (H. pylori). METHODS For manufacture of CaG-NANA, calcium (Ca) was combined with glycomacropeptide (GMP) by chelating, and N-acetylneuraminic acid (NANA) was produced with Ca-GMP substrate by an enzymatic method. The final concentration of each compo...
