Nanocrystalline particles of Cerium Oxide (CeO2) have been prepared by the chemical precipitation method using Cerium nitrate and Urea with a molar ratio of 1:2. The results revealed that the formation of CeO2 fine particles is influenced by molar ratio of metal nitrates to fuel. Well faceted CeO2 nanoparticles, were synthesized by thermal-assisted dissociation ...

BACKGROUND Despite the high prevalence of gastroesophageal reflux disease (GERD), its risk factors are still a subject of controversy. This is probably due to inadequate distinction between reflux esophagitis (RE) and non-erosive reflux disease (NERD), and is also due to inadequate evaluation of adjacent stomach. Our aim is therefore to define background factors of RE and NERD independently, ba...

BACKGROUND/AIMS Impedance-pH monitoring allows detailed characterization of gastroesophageal reflux and esophageal activity associated with reflux. We assessed the characteristics of nocturnal reflux and esophageal activity preceding and following reflux. METHODS Impedance-pH tracings from 11 healthy subjects and 76 patients with gastroesophageal reflux disease off acid-suppressive therapy we...

OBJECTIVE: Screening siblings of index patients with vesicoureteral reflux (VUR) has been proposed to identify children who are at risk for renal damage. However, screening siblings for VUR remains controversial. We investigated the prevalence of VUR and renal cortical abnormalities in the sibling population in a large cohort of families with VUR. METHODS: Between 1998 and 2012, parents of inde...

BACKGROUND/AIMS Available data about reflux patterns and symptom determinants in the gastroesophageal reflux disease (GERD) subtypes off proton pump inhibitor (PPI) therapy are lacking. We aimed to evaluate reflux patterns and determinants of symptom perception in patients with GERD off PPI therapy by impedance-pH monitoring. METHODS We retrospectively reviewed the impedance-pH data in patien...

BACKGROUND AND AIM The reason that some reflux episodes evoke symptoms is poorly understood, therefore the aim of this study is to assess the determinants of reflux perception in patients with non-erosive reflux disease (NERD) on proton pump inhibitor (PPI) therapy. METHODS Ten NERD patients with persistent symptoms, despite double-dose PPI therapy, were included in this study. All patients h...

nanocrystalline particles of cerium oxide (ceo2) have been prepared by the chemical precipitation method using cerium nitrate and urea with a molar ratio of 1:2. the results revealed that the formation of ceo2 fine particles is influenced by molar ratio of metal nitrates to fuel. well faceted ceo2 nanoparticles, were synthesized by thermal-assisted dissociation method at reflux temperature in a...

background gastroesophageal reflux disease is a common, chronic disease worldwide. the weekly prevalence of reflux in developed countries is 10% to 48%. it has previously been reported as 5% in asian countries, but new reports show a higher level in both asian and arab countries. in iran, reflux has increased over the last two decades. there are few studies concerning the prevalence of reflux i...

Non-erosive reflux disease (NERD) is the most common presentation of gastroesophageal reflux disease. Although acid reflux is the most important cause of symptom generation in NERD patients, non-acid reflux is also associated with reflux symptoms. The temporal relation between symptoms and reflux episodes is of importance in evaluating the results of combined pH-impedance monitoring in NERD pat...

Objective- Trigonella foenum graecum, (Fenugreek) has anti-inflammation, antiseptic and antidiabetic activities in traditional medicine. This study was performed to investigate the protection effects of Fenugreek seed extract on the experimental reflux esophigitis (RE) in rats. Design- experimental study. Animals- 24 male Wistar albino rats. Procedures- Rats were randomly allocated into 4 group...
