Oxidant/antioxidant status, estrogenic/anti-estrogenic activity and gene expression profile were studied in mice fed with Cystus incanus L. (Cistaceae) reach bee pollen from location in Central Croatia's Dalmatia coast and offshore islands. Seven phenolic compounds (out of 13 tested) in bee pollen sample were detected by high performance liquid(More)
In vivo study has been conducted on 47 healthy women and men in order to investigate whether daily intake of powdered propolis extract during 30 days has any influence on the following blood parameters: activity of superoxide dismutase, glutathione peroxidase and catalase, concentration of plasma malondialdehyde, total cholesterol, low- and high-density(More)
Native propolis was defined as propolis powder collected from the continental part of Croatia and prepared according to a patented process that preserves all the propolis natural nutritional and organoleptic qualities. Nine phenolic compounds (out of thirteen tested) in propolis sample were detected by high performance liquid chromatography (HPLC) analysis.(More)
The aim of this study was to correlate the activity of superoxide dismutase, catalase and glutathion peroxidase in liver and brain of 1, 4 and 18 months old CBA mice of both sexes. In liver, decreased superoxide dismutase and increased glutathione peroxidase activities were observed during aging in male mice. In brain, the increase of catalase and(More)
The opioid peptide methionine-enkephalin (MENK) has significant immunomodulatory ability in addition to its neurotransmitter function. Since neutral endopeptidase (NEP, CD10, enkephalinase EC 3.4.24.11) cleaves opioid peptides, the presence and activity of NEP in neutrophils from different persons might be responsible for the diverse, neuropeptide-induced,(More)
In cells living under optimal conditions, protein folding defects are usually prevented by the action of chaperones. Here, we investigate the cell-wide consequences of loss of chaperone function in cytosol, mitochondria or the endoplasmic reticulum (ER) in budding yeast. We find that the decline in chaperone activity in each compartment results in loss of(More)
Literature data support the hypothesis that oxidative stress and the accompanying antioxidant defense might play an important role in renal cell carcinoma (RCC) growth and progression. It is also known that the incidence of renal tumors is two times higher in men than in women. Thus, the aim of this study was to determine whether the oxidant/antioxidant(More)
The beneficial effects of hyperoxia have been noted in treatment of several diseases and pathological states. However, the excessive production of ROS under hyperoxic conditions can directly damage cellular macromolecules if the imbalance in antioxidant status exists. Cytochrome P450 (Cyp) 4a14 has an important role in the metabolism of lipids and as a(More)
Increased oxygen concentration (hyperoxia) induces oxidative damage of tissues and organs. Oxygen toxicity in hyperoxia is controlled by factors such as sex, age, tissue, strain and hormones. In most species females show lower incidence of some age-related pathologies linked with oxidative stress, which has been attributed to a beneficial effect of ovarian(More)
Cytochrome P450 monooxygenases (CYPs) represent large class of heme-containing enzymes that catalyze the metabolism of various endogenous and exogenous substrates. Although they are found in many tissues, the function of the particular subset of their isoforms does not appear to be the same. Many CYP genes exhibit sexually dimorphic expression, while others(More)
