INTRODUCTION Urinary calculi in infants are relatively infrequent, but their incidence has increased in the recent decades. The aim of this study was to investigate the clinical presentation, metabolic risk factors, and urinary tract abnormalities in infants suffering from kidney calculus. MATERIALS AND METHODS A total of 152 infants were admitted between 2009 and 2012 with ultrasonography-pr...

Oceans function as a sink for organochlorine compounds (OCs) such as PCBs and DDTs. Deep-sea fish bioaccumulate OCs to levels 10 to 100 times higher than shallow-water species. OCs induce the cytochrome P450 (CYP) system, the activity of which may increase reactive oxygen species (ROS) production in liver cells. However, the susceptibility of fish to the oxidative stress likely caused by OCs re...

INTRODUCTION Even though dehydration could aggravate formation of urinary calculi, the effects of fluid and food restriction on calculus formation is not thoroughly defined. The purpose of this study is to evaluate the effects of fluid and food restriction in Ramadan fasting on urinary factors in kidney and urinary calculus formation. MATERIALS AND METHODS Fifty-seven men aged 30 to 55 years ...

Cent Eur J Urol 2013; 66: 207-208 DOI: 10.5173/ceju.2013.02.art24 The concise yet poignant review article by Adamowicz et al. [1] appearing in this issue of the “Central European Journal of Urology” delves into two critical aspects of urinary bladder tissue engineering. The use of appropriate scaffolding material as an architectural foundation for bladder regeneration combined with multipotent ...

Selective breeding is an important tool in behavioral genetics and evolutionary physiology, but it has rarely been applied to the study of exercise physiology. We are using artificial selection for increased wheel-running behavior to study the correlated evolution of locomotor activity and physiological determinants of exercise capacity in house mice. We studied enzyme activities and their resp...

The influence of surfaces on the reactions of platelets in whole blood under laminar flow was investigated in a cone and plate viscometer. Citrated whole blood was exposed to steel, PMMA and PMMA modified with PEO at low (500 s(-1)) and high (4000 s(-1)) wall shear rates at room temperature for a period of 100 s. Treated blood samples were fixed with paraformaldehyde, stained with a monoclonal ...

BACKGROUND Aspirin is a cornerstone in management of coronary artery disease (CAD). However, considerable variability in the antiplatelet effect of aspirin has been reported. AIM To investigate independent determinants of reduced antiplatelet effect of aspirin in stable CAD patients. METHODS We performed a cross-sectional study including 900 stable, high-risk CAD patients. Among these, 795 ...

BACKGROUND Children with obstructive sleep apnea (OSA) have a higher rate of adverse post-extubation respiratory events, such as laryngospasm, upper airway obstruction, apnea, desaturation and/or need for re-intubation. They are overly sensitive to sedatives and narcotics. Although the etiology of OSA is primarily obstruction (mechanical or neuromuscular), a central element may contribute to OS...

Patients with symptomatic peripheral arterial occlusive disease have a claudication-limited peak exercise performance that is improved with exercise training. The effects of training on skeletal muscle metabolism were evaluated in 26 patients with claudication, randomized into a 12-wk program of treadmill training (enhances muscle metabolic activity in normal subjects), strength training (stimu...

It has been shown in the course of the last few years that the number of factors playing a part in calcium-phosphorus (Ca-P) metabolism is far greater than had been known. It was found that the calcification of bones depends in the first place on the 'citric acid cycle' and on adenosine triphosphate (ATP) (oxidative phosphorylation) (Dickens, 1941; Albaum, Hirshfeld and Sobel, 1952; Dixon and P...
