Gene therapy provides modern medicine with new perspectives that were unthinkable two decades ago. Progress in molecular biology and, especially, molecular medicine is now changing the basics of clinical medicine. Reports of long-term side effects of the first successful human gene therapy study have slowed the penetration of DNA usage into clinical(More)
N(G)-Nitro-L-arginine-methyl ester (L-NAME)-induced hypertension is a well established model of experimental hypertension. Although regression experiments are effective at approximating a clinical setting the reversal of already established L-NAME hypertension has not been intensively researched. We investigated whether spontaneous regression of L-NAME(More)
Mevalonic aciduria belongs to a group of rare inherited metabolic disorders related to cholesterol biosynthesis. The pathogenesis of mevalonic aciduria is not clear, although the cause is known - a genetic defect leading to a deficiency in mevalonate kinase activity. The lack of non-steroid isoprenoids in patients with mevalonic aciduria might cause(More)
OBJECTIVE Blood pressure enhancement induced by continuous light exposure represents an attractive but rarely investigated model of experimental hypertension. DESIGN AND METHODS The aim of this study was to show whether the combination of continuous light (24 h/day) exposure and chronic N-nitro-L-arginine-methyl ester (L-NAME) treatment induces(More)
Consumption of cola beverages is very high worldwide. The health effects of cola intake are not clear, although epidemiological studies point toward associations with obesity, kidney diseases and osteoporosis. Experimental studies are surprisingly rare. In this study, we substituted drinking water of adult male Wistar rats with three different cola(More)
Advanced glycation end products (AGEs) play a key role in the pathogenesis of diabetes and its complications, including the diabetic nephropathy. The renoprotective effects of exercise are well known; however, the mechanisms remain elusive. Here we examined whether a regular moderate exercise in obese Zucker rats (OZR), a model of diabetes- and(More)
Several bacterial species have inherent ability to colonize solid tumors in vivo. However, their natural anti-tumor activity can be enhanced by genetic engineering that enables these bacteria express or transfer therapeutic molecules into target cells. In this review, we summarize latest research on cancer therapy using genetically modified bacteria with(More)
The pathogenesis of cardiovascular complications of obstructive sleep apnea syndrome (OSAS) can be explained by oxidative and carbonyl stress due to oxygenation and reoxygenation injury during sleep. This hypothesis has yet to be proved experimentally, although several clinical observations have found increased oxidative damage in plasma. Continuous(More)
BACKROUND Oxidative stress plays a role in multiple sclerosis. Saliva can be potentially used to study the disease progression or treatment, because of its non-invasiveness and easy collection. But studies on saliva and multiple sclerosis are missing. The aim of this study was to compare the concentrations of salivary oxidative stress markers in patients(More)
Chronic kidney disease (CKD) represents a serious public health problem with increasing prevalence and novel approaches to renal protection are continuously under investigation. The aim of this study was to compare the effect of melatonin and angiotensin II type 2 receptor agonist compound 21 (C21) to angiotensin converting enzyme inhibitor captopril and(More)
