A product of incomplete combustion of diesel fuel, 3-nitrobenzanthrone (3-NBA), has been classified as a cancer-causing substance. It first gained attention as a potential urinary bladder carcinogen due to the presence of its metabolite in urine and formation of DNA adducts. The aim of the present study was to characterise the dose-response relationship of 3-NBA in human urothelial cancer cell line (RT4) exposed to concentrations ranging from 0.0003 µM (environmentally relevant) to 80 µM by utilising toxicological and metabolomic approaches...

Recent research suggested a metabolic implication of osteocalcin (OCN) in e.g. insulin sensitivity or steroid production. We used an untargeted metabolomics approach by analyzing plasma and urine samples of 931 participants using mass spectrometry to reveal further metabolic actions of OCN. Several detected relations between OCN and metabolites were strongly linked to renal function, however, a number of associations remained significant after adjustment for renal function. Intermediates of proline catabolism were associated with OCN reflecting the implication in bone metabolism...

BACKGROUND: Ileal pouch-anal anastomosis (IPAA) is the preferred surgical treatment for patients with chronic ulcerative colitis. Little is known about the impact of obesity on operative characteristics, short-term postoperative complications and long-term functional outcomes after IPAA. METHODS: A retrospective review of all patients undergoing IPAA for chronic ulcerative colitis at a single tertiary referral center between January 2002 and August 2013 was performed...

AIMS: The present study aims to evaluate the predominance of uropathogens responsible for urinary tract infection (UTI) and determine their resistance patterns, to assess if the recommended empirical treatment is appropriate for the studied population. Samples were collected in Aveiro (Portugal) from an ambulatory service between June 2011 and June 2014. RESULTS: From the 4,270 positive urine samples for UTI, 3,561 (83%) were from women and only 709 (17%) were from men...

OBJECTIVE: To evaluate the effects of surgical anatomical correction on lower urinary tract symptoms (LUTS) in patients with a pelvic anterior compartment defect (PACD). METHODS: This prospective study was carried out on 30 women who had stage II-IV PACD. The women were questioned regarding LUTS symptoms such as urgency, urge incontinence, frequency, hesitancy, abnormal emptying, nocturia and dysuria pre and postoperatively. After a 7-month follow up, the comparison of LUTS symptoms with respect to their healing, existence or de novo appearance was performed using the McNemar and Bowner and Wilcoxon signed-rank tests...

We studied the causes and predictors of death-censored kidney allograft failure among 1670 kidney recipients transplanted at our center in the corticosteroid-free maintenance immunosuppression era. As of January 1, 2012, we identified 137 recipients with allograft failure; 130 of them (cases) were matched 1-1 for recipient age, calendar year of transplant and donor type with 130 recipients with functioning grafts (controls). Median time to allograft failure was 29 months (interquartile range 18-51). Physician validated and biopsy confirmed categories of allograft failure were: acute rejection (21%), glomerular disease (19%), transplant glomerulopathy (13%), interstitial fibrosis tubular atrophy (10%), and polyomavirus-associated nephropathy (7%)...

Mycotoxins may affect animal health, including reproduction. Little is known about the clinical relevance of exposure of horses to contaminated feed. This study aimed at (i) monitoring the levels of the mycotoxins zearalenone (ZEN), with its metabolites α- and β-zearalenol (α- and β-ZOL), and sterigmatocystin (STC) in urine samples from thoroughbred mares in Japan and (ii) relating these findings to the potential effects on reproductive efficacy of breeding mares. Sixty-three urine samples of breeding mares from 59 breeding farms were used...

Previous studies investigating the relationship between sodium intake and blood pressure have mostly relied on dietary recall and clinic blood pressure measurement. In this cross-sectional study, we aimed to investigate the relationship between 24h urinary sodium and potassium excretion, and their ratio, with 24h ambulatory blood pressure parameters including nocturnal blood pressure dipping in patients with type 1 and 2 diabetes. We report that in 116 patients with diabetes, systolic blood pressure was significantly predicted by the time of day, age, the interaction between dipping status with time, and 24h urinary sodium-to-potassium ratio (R(2) =0...

A sequential on-line extraction, clean-up and separation system for the determination of betaine, L-carnitine and choline in human urine using column-switching ion chromatography with non-suppressed conductivity detection was developed in this work. Self-packed pretreatment column (50 mm×4.6 mm, i.d.) was used for the extraction and clean-up of betaine, L-carnitine and choline. The separation was achieved using self-packed cationic exchange column (150 mm×4.6 mm, i.d.), followed by non-suppressed conductivity detection...

Between 1996 and 1998, 477 dead otters from different Central European countries were examined for urolithiasis, including 449 free-ranging Eurasian otters (Lutra lutra) as well as 17 Eurasian otters and 11 Asian small-clawed otters (Aonyx cinerea) from captivity. In the free-ranging specimens, uroliths (sand or stones) were found in 105 animals (23.4%), with no significant difference (P = 0.77) between the sexes. Uroliths were not present in any juveniles (n = 26) and urolithiasis was not considered the main cause of death in any individual...

Four cases of obstructive urolithiasis occurred in male Visayan warty pigs (Sus cebifrons negrinus) during a 12-mo period. One animal died, two were euthanized, and one was treated successfully with a tube cystotomy procedure and a subsequent urinary acidification diet. Uroliths from two cases of urethral obstruction were analyzed and confirmed as calcium carbonate. A fifth nonobstructive case was suspected in an adult female in which calcium carbonate crystalluria was diagnosed, and that case was resolved with medical management...

To investigate the involvement of ICAM-1 in the adhesion of Candida to the genitourinary epithelial cells in high glucose, we examined the adhesion of Candida albicans or Candida glabrata to human vaginal epithelial cells (VK2/E6E7) or human vulvovaginal epidermal cells (A431). These cells were cultured in 100, 500 or 3000 mg/dL glucose for three days and inoculated with Candida for 60 minutes. Followed by, adhering of Candida to the cells, which were counted. While the adhesion of Candida albicans to VK2/E6E7 significantly increased in the high glucose, A431 did not...

INTRODUCTION: Sequencing peptides included in the urinary proteome identifies the parent proteins and may reveal mechanisms underlying the pathophysiology of chronic kidney disease. METHODS: In 805 randomly recruited Flemish individuals (50.8% women; mean age, 51.1 years), we determined the estimated glomerular filtration rate (eGFR) from serum creatinine using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. We categorized eGFR according to the National Kidney Foundation Kidney Disease Outcomes Quality Initiative guideline...

Idiopathic normal pressure hydrocephalus (iNPH) is characterized by a clinical triad (gait disturbance, dementia, and urinary incontinence), and by radiological findings of enlarged ventricles reflecting disturbance of central spinal fluid circulation. A diagnosis of iNPH is sometimes challenging, and the pathophysiological mechanisms underlying the clinical symptoms of iNPH remain largely unknown. Here, we used an emerging MRI technique, resting-state functional connectivity MRI (rsfcMRI), to develop a subsidiary diagnostic technique and to explore the underlying pathophysiological mechanisms of iNPH...

Post operative complications after pituitary tumour surgery vary according to procedure. There are several surgical procedures being done such as transcranial, transsphenoidal microsurgical and transsphenoidal endoscopic approaches. One of the commonest complications is diabetes insipidus (DI). Our main objective was to find out the incidence of diabetes insipidus in post operative period among patients undergoing surgical intervention for pituitary tumour in our institute. The presence of diabetes insipidus in the postoperative period was established by measuring serum Na+ concentration, hourly urine output and urinary specific gravity to find out the incidence of diabetes insipidus in postoperative period in relation to age, gender, tumour diameter, function of tumour (i...
