A Questionnaire-based Assessment of the Anxiety, Satisfaction and Discomfort Experienced by Japanese Cancer Patients during the Use of Central Venous Ports.

Objective A significant number of Japanese cancer patients refuse to have central venous (CV) ports implanted. The aim of this study is to investigate the experiences of patients prior to and after CV port implantation, as well as their expectations regarding the use of CV ports. Methods This study was carried out at Osaka Medical Center for Cancer and Cardiovascular Diseases from October 20, 2014, to January 16, 2015.

Increased eosinophilic cationic protein in nasal fluid in hospitalized wheezy infants with RSV infection.

Background: Respiratory syncytial virus (RSV) is a major respiratory pathogen which causes bronchiolitis with dyspnea and wheezing in children less than 2 years old. RSV bronchiolitis in infancy severe enough to cause hospitalization might be a risk factor for allergic sensitization and bronchial asthma in future. However, the pathophysiology behind this development has not been clearly characterized.

Efficacy and safety of continuous hemodiafiltration for acute decompensated heart failure.

The mortality of heart failure patients with renal insufficiency is high, and these patients tend to develop diuretic resistance. Under these conditions, continuous hemodiafiltration (CHDF) is a possible alternative volume reduction therapy to diuretics. However, its efficacy and safety are not clear.

Changes in the expression of cytochrome P450 genes in hemin-induced differentiated K562 cells.

We have previously reported the expression of CYP genes in human myeloblastic and lymphoid cell lines, and the induction of the CYP3A4 and GSTP1 genes by oxidative stress in the human erythroleukemia cell line, K562. To further elucidate the role of drug metabolizing enzymes in hematogenesis, we have characterized the expression of CYP genes in hemin-induced differentiated K562 cells. After incubation with 50 microM hemin for 3 d, the expression of CYP1A1 and CYP3A4 genes was induced by 2.

Evaluation of parathyroid hyperplasia by ultrasonographic examination in patients with end-stage renal failure before and at initiation of dialysis.

Secondary hyperparathyroidism (2HPT), which is related to renal osteodystrophy (ROD), may occur in patients in the comparatively early stage of chronic renal failure (CRF). Secondary hyperparathyroidism patients with parathyroid hyperplasia showed resistance to vitamin D(3) treatment during long-term dialysis. At present, evaluation by ultrasonography is considered to be useful for confirming parathyroid hyperplasia.

ATP-dependent transport of bile acid intermediates across rat liver peroxisomal membranes.

The bile acid intermediate 3alpha,7alpha,12alpha-trihydroxy-5beta-cholestanoic acid (THCA) is converted to cholic acid exclusively in peroxisomes by the oxidative cleavage of the side chain. To investigate the mechanism by which the biosynthetic intermediates of bile acids are transported into peroxisomes, we incubated THCA or its CoA ester (THC-CoA) with isolated intact rat liver peroxisomes and analyzed their oxidation products, cholic acid and 3alpha,7alpha,12alpha-trihydroxy-5beta-cholest-24-enoic acid. The oxidation of both THCA and THC-CoA was dependent on incubation time and peroxisomal proteins, and was stimulated by ATP.
