INTRODUCTION: The usefulness of carbon dioxide (CO2 ) gas digital subtraction angiography (DSA) has been reported for patients with renal insufficiency and allergy to iodinated contrast agents. However, CO2 gas cannot replace the iodinated contrast agent in all cases owing to some disadvantages. We describe balloon-occluded CO2 DSA (B-CO2 DSA) as an improved CO2 DSA procedure for interventions in the internal iliac artery (IIA) region and compare the quality of images obtained using conventional CO2 DSA and B-CO2 DSA...

Fluorination of [ScCl3(Me3-tacn)] (Me3-tacn = 1,4,7-trimethyl-1,4,7-triazacyclononane) and [ScCl3(BnMe2-tacn)] (BnMe2-tacn = 1,4-dimethyl-7-benzyl-1,4,7-triazacyclononane) by Cl/F exchange with 3 mol. equiv. of anhydrous [NMe4]F in CH3CN solution yields the corresponding [ScF3(R3-tacn)] (R3 = Me3 or BnMe2). These are the first examples of scandium fluoride complexes containing neutral co-ligands. The fluorination occurs stepwise, and using a deficit of [NMe4]F produced [ScF2Cl(Me3-tacn)]. Attempts to fluorinate [YCl3(Me3-tacn)], [YI3(Me3-tacn)], [LaCl3(Me3-tacn)(OH2)] or [MCl3(terpy)] (M = Sc, Y or La; terpy = 2,2':6'2''-terpyridyl) using a similar method were unsuccessful, due to the Cl/F exchange being accompanied by loss of the neutral ligand from the metal centre...

Hyperinsulinemia could have a role in the growing incidence of esophageal adenocarcinoma (EAC) and its pre-cancerous lesion, Barrett's Esophagus, a possible consequence of Gastro-Esophageal Reflux Disease. Obesity is known to mediate esophageal carcinogenesis through different mechanisms including insulin-resistance leading to hyperinsulinemia, which may mediate cancer progression via the insulin/insulin-like growth factor axis. We used the hyperinsulinemic non-obese FVB/N (Friend leukemia virus B strain) MKR (muscle (M)-IGF1R-lysine (K)-arginine (R) mouse model to evaluate the exclusive role of hyperinsulinemia in the pathogenesis of EAC related to duodeno-esophageal reflux...

Erosive tooth wear has recently been at the centre of attention and its prevalence of erosive tooth wear among adolescents in the Netherlands appears to be rising. The multifactorial nature of the aetiology of the condition makes it difficult to identify the relevant causal factors, both in individual cases and within the general population. Preventive intervention is indicated in those cases where (active) erosive tooth wear is diagnosed. Early diagnosis is important, especially in younger patients. Preventive measures, such as dietary advice and the use of fluoride, are recommended but the scientific evidence for their effectiveness is still limited...

Vesicoureteral reflux after renal transplantation is associated with increase risk of urinary tract infections, renal scarring, and graft failure. We describe a case of a 46-year-old woman with 2 transplant kidneys, one functioning and another nonfunctioning, presenting with pelvic pain after a bilateral periureteral bulking procedure. Diuretic renography was performed to exclude iatrogenic ureteral obstruction. This showed a normally functioning transplant kidney without obstruction and subsequent vesicoureteral reflux into the collecting system of the nonfunctioning transplant kidney...

Peroral endoscopic myotomy (POEM) is a groundbreaking procedure for treating esophageal achalasia, and many reports from various facilities have described its safety and efficacy. However, there have been few reports on adverse events. Here, we report a case of a patient with mediastinitis caused by delayed mucosal damage after POEM. This case was the most severe among all POEM cases at our hospital. A 58-year-old man had experienced dysphagia and chest tightness since he was around 50 years old. At a previous hospital, he had been diagnosed with nonerosive reflux disease and had undergone fundoplication...

Herein, novel magnetic TiO2 /Fe3 O4 /CoWO4 nanocomposites were fabricated using a simple refluxing method followed by a calcination step at 450 °C. Photocatalytic activity of these nanocomposites were studied by decomposing rhodamine B, methyl orange, and fuchsine dye contaminants under visible-light illumination. Among the fabricated photocatalysts, the TiO2 /Fe3 O4 /CoWO4 (30%) photocatalyst exhibited superior activity. The degradation rate constant for rhodamine B by this ternary nanocomposite was 8.5 and 5...

Background/Aims: Gastroesophageal reflux disease (GERD) is a common condition that can lead to significant morbidity. Laryngopharyngeal reflux (LPR) is a distinct clinical entity that can occur simultaneously with GERD, necessitating additional treatment measures. The degree of overlap and clinical predictors of LPR among patients with GERD remains unknown. We aim to measure the prevalence of LPR in patients with GERD and identify clinical predictors. Patients and Methods: We performed a cross-sectional study involving patients with confirmed GERD according to the GERD questionnaire (GerdQ) using the reflux symptom index (RSI)...

BACKGROUND: Chronic rhinosinusitis (CRS) increases the risk of developing nasopharyngeal carcinoma (NPC) while nasopharyngeal reflux is known to be one of the major aetiological factors of CRS. Bile acid (BA), the component of gastric duodenal contents, has been recognised as a carcinogen. BA-induced apoptosis was suggested to be involved in human malignancies. Cells have the potential and tendency to survive apoptosis. However, cells that evade apoptosis upon erroneous DNA repair may carry chromosome rearrangements...
