Gastric cancer risk is varied among different regions of Thailand. We examined the characteristics of Helicobacter pylori infection in two regions of Thailand. The H. pylori status of 273 dyspeptic patients (136 from the South and 137 from the North; a low and high incidence of gastric cancer region, respectively) was evaluated, and virulence genotypes (cagA, vacA, hrgA and jhp0562-positive/β-(...
BACKGROUND Malignant tumours of the stomach are common, but the incidence of stomach cancer varies from country to country, probably a result of genetic, epigenetic and environmental factors. Stomach cancer often occurs in older people whose stomachs produce only small quantities of acid.

OBJECTIVE To determine whether vitamin D status predicts disease activity in patients with multiple sclerosis (MS) taking interferon-β (IFN), glatiramer acetate (GA), and fingolimod (FTY). METHODS Participants (n = 324) with relapsing-remitting MS on IFN (96), GA (151), or FTY (77) were identified from the Comprehensive Longitudinal Investigation of MS at Brigham and Women's Hospital (CLIMB) ...
خلاصه: سابقه و هدف: هلیکوباکتر پیلوری به عنوان عاملی برای زخم گاستریت و زخم پپتیک مطرح است و یک عامل خطرساز برای سرطان معده محسوب می شود. شیارهای لثه در دندان افراد مبتلا به پریودنتیت مزمن ممکن است به عنوان یک مخزن برای هلیکوباکتر پیلوری عمل کنند. لذا، هدف از مطالعه حاضر، بررسی ژن های هلیکوباکترپیلوری جدا شده از پلاک های دندانی و ارتباط آن با زخم های گوارشی می باشد. مواد و روش ها: مطالعه ...
Background & Aim: Apical extrusion of debris is one of the reasons for flare-up(pain,swelling,or both). This study aimed to determine the apical debris extrusion of two rotary systems(RaCe and Komet F6 SkyTaper) in curved mesiobuccal canals of mandibular first molars. Material and methods: Thirty mandibular first molars (with mesiobuccal canal curvature 25-35 degree) were included in this ex...
Worldwide, gastric cancer is still a leading cause of cancer deaths. The association of Helicobacter pylori and gastric cancer is well established, and the bacterium was declared a class one carcinogen by the International Agency for Research on Cancer and the World Health Organisation in 1994. H pylori infection is responsible for 5.5% of all global cancers, 75% of non-cardia gastric cancer an...
