Monocytic cells represent important cellular elements of the innate and adaptive immune responses in viral infections. We assessed the role of Fas/FasL in promoting monocyte apoptosis during HSV-2 infection by using an in vitro model based on the murine RAW 264.7 monocytic cell line and an in vivo murine model of HSV-2 infection applied to C57BL6,(More)
INTRODUCTION Pathomechanism of HRS is still poorly understood. The aim of our study was: (1) to test whether different strains of rats could develop typical HRS, and (2) to estimate the influence of activation and inhibition of nitric oxide for development of renal failure in course of HRS. MATERIAL AND METHODS First, we used 16 of Wistar and 16 of(More)
The aim of the study was to determine the usefulness of interleukin 18 (IL-18) and neutrophil-gelatinase associated lipocalin (NGAL) in the risk assessment of contrast nephropathy in children. The study included patients among whom radiological examinations were performed using intravascular contrast agent. The material consisted of 33 children (19 girls,(More)
BACKGROUND Short-term administration of Galactosamine to experimental animals causes liver damage and acute liver failure (ALF), as well as acute renal failure in some cases. The aim of our study was to describe kidney disorders that developed in the course of galactosamine-induced liver failure. MATERIAL AND METHODS Sprague-Dawley rats were randomly(More)
Urolithiasis is recurrent chronic disease and a complex nephro-urological problem. Currently it is diagnosed in very young children, even infants in the first quarter of life. Until recently the main method of treatment for stones, which for various reasons did not pass spontaneously, was open surgery. At present, the main method replacing open surgery is(More)
Angiogenesis is a multi-stage process of new vessel development which involves migration, proliferation and differentiation of endothelial cells. Pathological angiogenesis plays a crucial role in the pathomechanism of various ischemic, malignant and inflammatory disorders. Among eye diseases, macular degeneration (AMD) and proliferative diabetic retinopathy(More)
Aloe vera (Aloe arborescens, aloe barbadensis) is a medicinal plant belonging to the Liliaceae family. Aloe vera gel prepared from the inner part of Aloe leaves is increasingly consumed as a beverage dietary supplement. Some data suggest its tumor growth modulatory properties. The aim of the present study was to evaluate in Balb/c mice the in vivo influence(More)
UNLABELLED PADMA 28 is a herbal multicompound remedy that originates from traditional Tibetan medicine and possesses anti-inflammatory, antioxidant, antimicrobial, angioprotecting, and wound healing properties. The aim of the present study was to evaluate the influence of this remedy on immunological angiogenesis and granulocytes metabolic activity in(More)
BACKGROUND CD105 was postulated as a renal cell carcinoma (RCC) stem cell marker, and CD133 as a putative RCC progenitor. Hypoxia, a natural microenvironment that prevails in tumors, was also incorporated into the study, especially in terms of the promotion of hypothetical stem-like cell properties. METHODS Within this study, we verify the existence of(More)
BACKGROUND Recent advancement in cancer research has shown that tumors are highly heterogeneous, and multiple phenotypically different cell populations are found in a single tumor. Cancer development and tumor growth are driven by specific types of cells-stem cell-like cancer cells (SCLCCs)-which are also responsible for metastatic spread and drug(More)
