BACKGROUND Recent studies identified mesenchymal stem cells (MSC) as major players in vascular remodelling and the sub-endothelial compartment as the stem cell niche. The uraemic microenvironment predisposes to increased levels of reactive oxygen species, accelerated ageing of endothelial cells (EC) and vascular sclerosis. METHODS We generated an in vitro model of a vascular niche consisting ...

venous limbs of the shunt is removed and the patient is connected to the dialyser. At the end of dialysis the U-tube is replaced. The use of the Scribner shunt in intermittent haemodialysis for chronic renal failure is well recognized, and Chisholm (1961) has advocated its use in some patients with acute renal failure and especially those who have few available veins. It is our belief that it s...

The interferon-gamma release assay (IGRA) is useful for diagnosing latent tuberculosis infection (LTBI), however the rate of negative conversion is high, especially in dialysis patients. Few studies have focused on predicting persistently positive patients who are at high risk of tuberculosis reactivation. We screened dialysis patients, and used QuantiFERON-TB Gold In-tube (QFT-GIT) to identify...

conclusions this study showed that some properties of antimicrobial substances produced by the ga strain differed from other peptide antibiotics produced by the genus bacillus such as bacitracin, which increases the likelihood of its novelty. results the isolated bacterium was identified as a new strain of bacillus atrophaeus. the antimicrobial substance exhibited heat stability between 25ºc an...

Measurements of electrical potential difference (pd) and of absorption by a dialysis method were carried out in the terminal ileum of patients with an ileostomy. The pd measured with saline in the lumen and at a few centimetres within the stoma averaged 9.2 mV, lumen negatively charged. The pd values were similar whether the ileostomy had been recently or long established. The pd rose considera...

Zr-PILC synthesis Two grams of a montmorillonite rich clay (for instance Bentonite CAS-No-1302-78-9) in 200 mL of water are stirred for a minimum of 2 hours, but preferably overnight. 50 mL of an aqueous 0.1 mol/L Zirconium(IV) oxychloride octahydrate (ZrOCl2·8H2O; CAS-No-13520-92-8) solution are then dropwise added to the clay dispersion (an isobaric dropping funnel can be used) under strong s...

introduction: peritoneal dialysis is an established form of renal replacement therapy used in many patients with end – stage renal disease . peritoneal dialysis has different complications this study was conducted in order to evaluate its complications and different survival probabilities of factors in shahid rahnemoon hospital . methods: in this retrospective, historical cohort study, reports ...

A 45-year-old woman with type 1 diabetes and chronic renal failure on dialysis underwent simultaneous pancreas-kidney transplantation from a brain dead donor. On postoperative day 15, acute generalized peritonitis was diagnosed and emergency laparotomy was performed. Perforation of the donor duodenum was found, which had apparently resulted from duodenal compression by the tip of the intestinal...

The purpose of this study was to describe the life-sustaining treatment preferences of dialysis patients and to compare the acceptability of two generic and a disease-specific advance directive (AD). Of 532 potentially eligible hemodialysis patients, 95 (17.9%) participated in the study. These patients completed two generic (the Centre for Bioethics Living Will and the Medical Directive) and on...
