In this retrospective study, records of Iranian Hajj pilgrims who were hospitalized in 2 Iranian hospitals in Mecca and Medina, Saudi Arabia, from 2005 to 2007, were reviewed. Of 600 patients who were hospitalized, 12 (2.0%) were admitted due to nephrological causes, which included kidney calculi (n = 7; 58.4%), acute kidney failure (n = 2; 16.7%), urinary tract infection (n = 1; 8.3%), urinary...

The goal of this study was to determine whether short-term fasting changes in urinary biomarkers related to oxidative stress: malondialdehyde (MDA), 8-isoprostaglandin F2alpha (8-isoPGF), 8-hydroxydeoxy-guanosine (8-OHdG) and 1,N6-ethenodeoxyadenosine (epsilondA) among female volunteers participating in the short-term fasting program in South Korea. The study subjects were 52 healthy women (mea...

BACKGROUND Vitamin-D-binding protein (VDBP) is a low molecular weight protein that is filtered through the glomerulus as a 25-(OH) vitamin D 3/VDBP complex. In the normal kidney VDBP is reabsorbed and catabolized by proximal tubule epithelial cells reducing the urinary excretion to trace amounts. Acute tubular injury is expected to result in urinary VDBP loss. The purpose of our study was to ex...

Indwelling urinary catheters may act as a reservoir of bacteria and cause urinary tract infections. Removal of the bacteria adherent to a urinary catheter should reduce the incidence of catheter-associated urinary tract infections. Using several N-acylated amino acids with combinations of four different acyl residues, we investigated their efficacy in removing adherent bacteria from catheter ma...

N-Butyl-N-(4-hydroxybutyl)nitrosamine (BBN) is a potent carcinogen in the urinary bladder of animals. The BBN model of bladder cancer is an excellent model of human urinary bladder cancer and has already led to a greater knowledge of its pathogenesis. In our studies, histogenesis and morphological characteristics of BBN urinary bladder cancer were analyzed in different animal species such as ra...

Angiotensin-converting enzyme 2 (ACE2) is expressed in the kidney and may be a renoprotective enzyme, since it converts angiotensin (Ang) II to Ang-(1-7). ACE2 has been detected in urine from patients with chronic kidney disease. We measured urinary ACE2 activity and protein levels in renal transplant patients (age 54 yrs, 65% male, 38% diabetes, n = 100) and healthy controls (age 45 yrs, 26% m...

Since the sodium salt of ascorbic acid (AA) promoted two-stage urinary bladder carcinogenesis in rats, whereas AA itself did not, the roles of the urinary sodium ion concentration and pH on urinary bladder carcinogenesis were investigated. Male F344 rats were given 0.05% N-butyl-N-(4-hydroxybutyl)nitrosamine in their drinking water for 4 weeks and then treated with basal diet containing 5% AA p...

OBJECTIVE: We aimed to evaluate the demographic, laboratory and radiological results of patients who applied emergency department due renal colic (RC) during Ramadan.MATERIAL AND METHODS: This retrospective cross-sectional study included (ED) with a diagnosis RC 2019 Ramadan 1 month preceding Ramadan. Age, sex, hour application, urinalysis (erythrocyturia, leukocyturia, ketonuria, urine density...

background: toluene is a harmful substance still being used as a solvent and catalyst in many industries that can increase the level of urinary hippuric acid (uha). this study was designed to examine the level of toluene and uha among workers of industrial site in seven companies in sidoarjo, indonesia and to analyze the risk factors for abnormal uha. methods: this study was an analytical cross...

Measurement of leukotriene E4 (LTE4) in urine is a noninvasive method for assessing changes in the rate of total body cysteinyl leukotriene production. Eosinophil protein X (EPX) has been used to assess eosinophil activity and monitor inflammation in bronchial asthma. The aim of the study was to look for differences in urinary LTE4 and EPX concentrations between children with stable atopic asth...
