OBJECTIVES To investigate the activities of the main antioxidative enzymes and oxidative stress in women with depressive disorder (DD). METHODS In 35 drug-naive women with DD and 35 age matched healthy women enzymes superoxide dismutase (CuZnSOD), catalase (CAT), glutathione peroxidase (GPX1), glutathione reductase (GR) and paraoxonase (PON1),(More)
Polyunsaturated fatty acids of n-3 series (n-3 PUFA) were shown to increase basal fat oxidation in humans. The aim of the study was to compare the effect of n-3 PUFA added to a very low calorie diet (VLCD), with VLCD only during three-week inpatient weight reduction. Twenty severely obese women were randomly assigned to VLCD with n-3 PUFA or with placebo.(More)
BACKGROUND Fatty acids are substantial components of lipids and cell membranes in the form of phospholipids. This review consists of two parts. The present part aims at describing fatty acid classification, dietary sources and biological functions. The second part will focus on fatty acid physiological roles and applications in human health and disease. (More)
Pancreatic cancer (PC) is one of the most frequent gastrointestinal malignancies with extremely poor prognosis. In spite of a relative low incidence of PC, in comparison with other cancers, PC is the fourth leading cause of cancer death in USA in both sexes. The available data clearly suggest that diabetes mellitus (DM) can be both a long-standing cause of(More)
The aim of this study was to investigate the effect of the microsomal triglyceride transfer protein (MTP) -493G/T polymorphism on clinical and biochemical parameters in relation to the presence of metabolic syndrome (MS). A group of 270 participants, 143 men and 127 women [50 men/36 women fulfilled the International Diabetes Federation (IDF) criteria of(More)
Human paraoxonase 1 (PON1) has been shown to decrease the level of systemic oxidative stress, which is thought to contribute to cancer development. The aim of this study was to examine the interrelationships between PON1 status and some clinical characteristics in patients with pancreatic cancer (PC). A group of 73 consecutive patients with PC (stage II-IV)(More)
Fourteen pairs of obese female monozygotic twins were recruited for a study of genetic influences on serum and adipose fatty acid (FA) composition. Following 1 wk of inpatient stabilization, fasting serum and adipose tissue obtained by surgical excision were analyzed by thin-layer and gas chromatography. Intrapair resemblances (IPR) for individual FA were(More)
Paraoxonase 1 is believed to play a role in preventing lipid oxidation and, thus, limiting production of proinflammatory mediators. Systemic inflammatory response in sepsis increases oxidative stress and decreases high-density lipoprotein (HDL) concentrations. The objective of this study was to investigate serum paraoxonase 1 activities in critically ill(More)
BACKGROUND This is the second of two review parts aiming at describing the major physiological roles of fatty acids, as well as their applications in specific conditions related to human health. RESULTS The review included the current literature published in Pubmed up to March 2011. In humans, fatty acids are a principle energy substrate and structural(More)
UNLABELLED The aim of this study was to analyze the relationship of serum leptin as well as adiponectin and the manifestation of pancreatic cancer (PC). Serum leptin, adiponectin, glucose homeostasis and insulin resistance (expressed as HOMA-IR) were investigated in 64 patients with newly diagnosed PC and compared with 64 healthy controls (CON group) and 75(More)
