BACKGROUND Paraoxonase-1 (PON1) is a HDL-attached extracellular esterase which is believed to contribute to the anti-atherogenic and anti-inflammatory properties of HDL. A decrease in PON1 is a risk factor for cardiovascular disease and has recently been found to be associated with juvenile obesity. The issue of a possible association between enzyme(More)
Adipocyte fatty acid-binding protein (A-FABP) links obesity and metabolic syndrome (MetS) and might be targeted in future therapies. Its utility as a MetS biomarker has been suggested in adults but has not been examined in children/adolescents. Our objectives were to identify metabolic parameters associated with A-FABP elevation in children and adolescents(More)
BACKGROUND Recent data indicates that nuclear ubiquitous casein and cyclin-dependent kinases substrate (NUCKS) may play role in tumor growth. In present study authors examined whether photodynamic therapy with 5-aminolevulinic acid (5-ALA) induces NUCKS expression in breast cancer cell line, MCF-7. METHODS In the experiment concentration of 5-ALA was(More)
BACKGROUND There are proteins, responsible for many basic cell functions (transmission of extracellular signals to cytoplasm or nucleus, cell growth, proliferation, migration, survival), which are activated and overexpressed in response to acute oxidative stress, especially tyrosine kinases. The oxidative stress-associated Src activator/Homo sapiens(More)
BACKGROUND The association of visfatin, an adipocytokine relevant to the development of inflammation and metabolic disorders, with juvenile obesity needs to be re-established as previously used tests occurred to be nonspecific. OBJECTIVE To evaluate visfatin association with a metabolic profile of 88 overweight/obese and 26 lean children/adolescents as(More)
Lactate dehydrogenase (LDH) from the pig heart interacts with liposomes made of acidic phospholipids most effectively at low pH, close to the isoelectric point of the protein (pH = 5.5). This binding is not observed at neutral pH or high ionic strength. LDH-liposome complex formation requires an absence of nicotinamide adenine dinucleotides and adenine(More)
Careful selection of housekeeping genes (HKG) is prerequisite to yield sound qPCR results. HKG expression varies in response to hypoxia but the effect of manipulations of serum availability, a common experimental procedure, remains unknown. Also, no data on HKG expression stability across colon adenocarcinoma lines that would aid selection of normalizers(More)
Photodynamic therapy (PDT) is a well-known method for the treatment of malignant tumors, and its principles have been well established over the past 30 years. This therapy involves the application of a chemical called a photosensitizer and its subsequent excitation with light at the appropriate wavelength and energy. Topical photodynamic therapy with(More)
