W I Mortada, I M M Kenawy, Y G Abou El-Reash, A A Mousa
Microwave assisted preparation of cellulose modified with Gallic acid (MA-Cell-GA) was developed for high efficient adsorption of Al(3+). The as-prepared modified cellulose has been characterized by elemental analysis, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), transmission electron microscopy (TEM) and zeta potential measurements. Energy dispersive X-ray (EDX) spectrum was utilized to proof the adsorption of Al(3+). The effect of various experimental factors, as pH, amount of adsorbent, shaking time, initial metal ion concentration, temperature, concomitant ions and desorption conditions on the extraction efficiency was investigated and optimized in batch mode experiments...

BACKGROUND: Proton pump inhibitors and laparoscopic anti-reflux surgery (LARS) offer long-term symptom control to patients with gastro-oesophageal reflux disease (GERD). AIM: To evaluate the process of 'normalisation' of the squamous epithelium morphology of the distal oesophagus on these therapies. METHODS: In the LOTUS trial, 554 patients with chronic GERD were randomised to receive either esomeprazole (20-40 mg daily) or LARS. After 5 years, 372 patients remained in the study (esomeprazole, 192; LARS, 180)...

OBJECTIVE: Gastroesophageal reflux disease (GERD) is a common disease which can cause troublesome symptoms and affect quality of life. In addition to esophageal complications, GERD may also be a risk factor for extra-esophageal complications. Both GERD and coronary artery disease (CAD) can cause chest pain and frequently co-exist. However, the association between GERD and acute myocardial infarction (AMI) remain unclear. The purpose of the study was to compare the incidence of acute myocardial infarction in GERD patients with an age-, gender-, and comorbidity matched population free of GERD...

BACKGROUND: Gastroesophageal reflux disease (GERD) is common in patients with obesity. Diagnosing GERD is important as bariatric operations have different influence on GERD. We assessed reflux symptoms and objective findings prior to surgery. METHODS: Work-up included esophageal symptoms quantification by VAS-scores, esophagogastroduodenoscopy (EGD) and 24-h impedance-pH (imp-pH) monitoring off PPI therapy. Imp-pH was classified as abnormal if either %time pH<4 was abnormal, total number of reflux episodes was elevated or symptom index (SI) was positive...

BACKGROUND: Proton pump inhibitors (PPIs) are a class of medications that reduce acid secretion and are used for treating many conditions such as gastroesophageal reflux disease (GERD), dyspepsia, reflux esophagitis, peptic ulcer disease, and hypersecretory conditions (e.g. Zollinger-Ellison syndrome), and as part of the eradication therapy for Helicobacter pylori bacteria. However, approximately 25% to 70% of people are prescribed a PPI inappropriately. Chronic PPI use without reassessment contributes to polypharmacy and puts people at risk of experiencing drug interactions and adverse events (e...

OBJECTIVE: Gastro-oesophageal reflux is considered to be an important contributing factor in chronic unexplained cough. It remains unclear why some reflux episodes in the same patient causes cough while others do not. To understand more about the mechanism by which reflux induces cough, we aimed to identify factors which are important in triggering cough. DESIGN: In this multicentre study, 49 patients with reflux-associated chronic cough were analysed using 24-hour pH-impedance-pressure monitoring...

1. Proton pump inhibitors have been extensively used for the treatment of ailments due to increased gastric acid secretion such as peptic ulcers, gastroesophageal reflux disease etc. 2. There are several approved drugs in the proton pump inhibitor class with the latest entries representing single enantiomer drugs of the previously approved racemic drugs. 3. Despite having a high degree of structural resemblance, rabeprazole, was shown to possess some unique differentiation from other drugs in the class. One of the key distinguishing features of rabeprazole was related to the lesser involvement of polymorphic metabolism in its pharmacokinetic disposition...

Thiazole derivatives are produced by using one-pot multicomponent reactions of acid chlorides, potassium thiocyanate, amino acids, alkyl bromides and ZnO nanorods (NR-ZnO) as the catalyst in water at ambient temperature. These reactions were not performed without using NR-ZnO as the catalyst. Nanorods of ZnO have been prepared by reflux procedure using sodium dodecylsulfate (SDS). Nanorods of ZnO showed a considerable improvement in the field of the product and displayed significant reusable activity.

OBJECTIVES: Ineffective esophageal motility (IEM) is characterized by well-defined manometric criteria. However, much variation exists within the diagnosis: Some patients exhibit exactly the required five weak swallows to make the diagnosis. Others show consistently ineffective swallows with total absence of any normal swallow. "We hypothesize" there are two different manometric subtypes of IEM; IEM Alternans (IEM-A) and IEM Persistens (IEM-P). METHODS: A total of 231 IEM patients were identified by high-resolution manometry (HRM)...

Gastroesophageal reflux disease (GERD) is defined as a condition which develops when the reflux of gastric contents causes troublesome symptoms, impairs quality of life, or leads to mucosal damage or complications. There are two main phenotypic presentations of GERD, the erosive (ERD) and non-erosive reflux disease (NERD), with the latter one representing up to 70% of GERD spectrum. Moreover, patients with GERD can be clinically subdivided into two distinct syndromes: patinets with esophageal and extraesophageal symptoms...

BACKGROUND: Functional dyspepsia (FD or non-ulcer dyspepsia) is defined as continuous or frequently recurring epigastric pain or discomfort for which no organic cause can be found. Acid suppressive therapy, including proton pump inhibitors (PPIs), has been proposed as a therapeutic option in FD, but its efficacy remains controversial. While PPIs are generally considered safe and well tolerated, they have been associated with adverse events, especially in the long term. For this reason, decisions on whether to initiate or continue PPI therapy should be made based on an appropriate clinical indication...
