Gastroesophageal reflux disease (GERD) is caused by abnormal reflux of gastric contents into the esophagus. GERD can be divided into two groups, erosive esophagitis and non-erosive reflux disease (NERD). The aim of this study was to compare the clinical characteristics of patients with erosive esophagitis to those with NERD. All participating patients underwent an upper endoscopy during a volun...

We investigated comparison according to reflux esophagitis and non-erosive reflux disease about "daily" symptom improvement for proton pump inhibitor treatment. We enrolled 57 reflux esophagitis and 90 non-erosive reflux disease patients. They took rabeprazole 10 mg/day for 28 days and completed "daily" in the Frequency Scale for the Symptoms of GERD from baseline until day 14, and after 28 day...

OBJECTIVE To estimate the prevalence of erosive disease in first carpometacarpal joints (CMCJs) and investigate its clinical impact compared with radiographic thumb base (TB) osteoarthritis (OA). PATIENT AND METHODS Standardized assessments with hand radiographs were performed in participants of two population-based cohort studies in North Staffordshire with hand symptoms lasting ≥1 day in th...

BACKGROUND Erosive esophagitis is a common condition in the western population. However, the prevalence and risk factors of this disorder in Taiwan remain unclear. This study investigated the current prevalence of erosive esophagitis in Taiwan and attempted to identify the risk factors for this disease. METHODS From January 2008 to May 2009, 2040 consecutive subjects who underwent upper gastr...

BACKGROUND The aim of the present in vitro study was to evaluate the protective effects of a zinc-hydroxyapatite toothpaste on repairing enamel erosion produced by a soft drink (Coca-Cola) compared to toothpastes with and without fluoride using Scanning Electron Microscopy (SEM). MATERIAL AND METHODS Fifty specimens were assigned to 5 groups of 10 specimens each. (Group 1: no erosive challeng...

OBJECTIVES To analyse the factors predicting erosive-deforming arthropathy in patients with psoriatic arthritis (PsA). METHODS A prospective cohort study was undertaken with 71 patients diagnosed as having PsA (44 men and 27 women, mean age 47 (SD 12) years). At the recruitment period patients had disease without evidence of radiological damage. Patients were studied and followed up according...

Erosive osteoarthritis of the hands of unusually early onset and severity was seen in two patients treated for chronic renal failure by long term haemodialysis and renal homograft respectively. The significance of this observation is discussed in the light of previous studies of erosive arthropathy in patients with chronic renal failure. Factors associated with chronic renal failure may predisp...

Abstract Recently, impact experiments in space have been conducted planetary exploration using hollow or internally structured projectiles. In laboratory projectiles to investigate the differences crater and ejecta from case of solid projectiles, a plume perpendicular target surface has observed, which not seen conventional cratering this study, we crater-formation resin understand mechanism th...

Abstract To investigate the cavitation and hydrodynamic characteristics of supercavitating projectiles in shear flow, Mixture multiphase Schnerr-Sauer models are employed to simulate underwater projectiles. The inflow average velocity is 600 m/s, rates range from 0 7500 s −1 . In uniform supercavity enveloping vertically symmetrical. drag dominated by pressure drag, lift coefficient 0. However,...

We studied the energy distributions of electrons emitted in the interaction of slow Na ions with polycrystalline Al surfaces. To study sub-threshold plasmon excitation we performed measurements as a function of emission angle which showed the excitation of bulk plasmons, confirming the kinetic nature of the excitation process. Electron spectra show narrow transition lines due to Auger decay in ...
