Vasopressin increases the net transport of sodium across the isolated urinary bladder of the toad by increasing the mobility of sodium ion within the tissue. This change is reflected in a decreased DC resistance of the bladder; identification of the permeability barrier which is affected localizes the site of action of vasopressin on sodium transport. Cells of the epithelial layer were impaled ...
Disruption of the epithelial barrier function has been recently associated with a variety of diseases, mainly at intestinal level, but also affecting the respiratory epithelium and other mucosal barriers. Non-pharmacological approaches such as xyloglucan, with demonstrated protective barrier properties, are proposed as new alternatives for the management of a wide range of diseases, for which m...
Changes in the urothelial barrier are observed in patients with cystitis, but whether this leads to inflammation or occurs in response to it is currently unknown. To determine whether urothelial barrier dysfunction is sufficient to promote cystitis, we employed in situ adenoviral transduction to selectively overexpress the pore-forming tight junction-associated protein claudin-2 (CLDN-2). As ex...
this field study was conducted to investigate barriers to applying principles of management in wards of tehran university on medical science hospitals: head nurses' viewpoints .75 hednurses who were working in selected hospitals affiliated to tehran university of medical sciences. the data collection tool was a questionnaire that it,s validity and reliability was obtained using content...
background: due to difficulty of obtaining a 24h urine (especially in children), a random urine calcium sample is recommended to detect of hypercalciuria. however, recent studies have shown that the urinary calcium/creatinine ratio varies with age and geographic areas. so, the aim of this study was determining the normal value of urinary calcium to creatinine ratio in healthy adolescent’s child...
conclusions vur might be more frequent in children with physiological urinary incontinence than the normal population, and might be as common as nmne with intermittent daytime incontinence. results urinary tract infection was found in 23 (34.8%) children, 17 (33.3%) and 6 (40%) patients with nmne and physiological urinary incontinence, respectively. out of 48 patients who underwent vcug, vesico...
Critical to the design and assessment of interventions for enteropathy and its developmental consequences in children living in impoverished conditions are non-invasive biomarkers that can detect intestinal damage and predict its effects on growth and development. We therefore assessed fecal, urinary and systemic biomarkers of enteropathy and growth predictors in 375 6-26 month-old children wit...
Alfred Bernard, PhD, Unit of Industrial Toxicology and Occupational Medicine, Clos Chapelle-aux-Champs 30.54, B-1200 Brussels (Belgium) Dear Sir, Glycosaminoglycans (GAG) are the major constituents of the anion layer of the glomerular basement membrane which provides an electrostatic barrier to the filtration of anionic macromolecules like albumin [1]. It has been recently suggested that the in...
cystoscopy and urinary cytology are currently the basis for diagnosis and follow-up of bladder tumors. research to find a sensitive and specific tumor marker for diagnosis of bladder tumor is actively underway, however, due to low sensitivity and high cost of cytology. this cross-sectional study was performed in 65 patients to evaluate whether urinary bladder cancer (ubc) antigen level can ...
