Opis:
Chronic inflammation is characterized by excessive production of cytokines and eicosanoids and is associated with unsufficient resolution. Supplementation with n-3 fatty acids may result in a lower incidence of many inflammatory diseases. The aim of this study was to determine the effect of α – linolenic acid (ALA) on the fatty acids profile of cell membranes and on the pro-inflammatory proteins cyclooxygenase – 2 (COX-2), prostaglandin E2 synthase (cPGES) and prostaglandin F2α receptor (FP) expression in murine RAW 264.7 macrophages, activated with lipopolysaccharide (LPS). It has been shown that COX-2, cPGES as well as FP receptor expression was highest in cells activated by LPS. In macrophages supplemented with ALA and activated with LPS a pro-inflammatory protein levels were significantly reduced, suggesting anti-inflammatory activity of α-linolenic acid. There were also statistically significant changes in the fatty acid profile after incubation of the RAW 264.7 cells for 48 hours with ALA. A deficiency or excess of specific fatty acids affect the cellular membrane fluidity, can also cause changes in cell morphology. Therefore it is appropriate to carry out further research on the ALA properties.

Opis:
It was reported that dietary fructose imposes a number of effects on lipid metabolism including hypertriglyceridemia. The daily intake of fructose in humans is mainly due to sucrose. It was reported that the consumption is still increasing, making a background for health implications. The mechanism of metabolic disorders is poorly understood, but a lot of studies indicate that the liver lipid homeostasis deregulation is essential for a fructose effect on metabolism. The aim of the study is to estimate if fructose affects the profile of fatty acids in in vitro and in vivo models. In this study in vitro and in vivo experiments were conducted to assess the effect of dietary fructose on the fatty acid profile in the cell culture or in the liver of rats. The results showed that in the fructose experimental groups, both in the cell and liver homogenates, the content of the saturated fatty acids were significantly higher than in control groups. According to the obtained data fructose in the medium and in the diet affects saturation of fatty acids in the cell cultures and in the livers of rats. The findings obtained in the experiments support the thesis that fructose influences the homeostasis of lipid metabolism in the liver and may give an opportunity to discuss the limitation of the content of this kind of sugar in food.

Opis:
Zinc is a microelement essential for the body. It has a great impact on the proper development and renewal of tissues, reproductive system, skin condition, or immune processes. Zincis involved practically in all aspects of the immune system and the production and activation of white blood cells. This work aimed to determine the effect of zinc oxide nanoparticles (ZnONP) on the expression of pro-inflammatory proteins in murine macrophages RAW 264.7, activated with lipopolysaccharide (LPS). Using the immunodetection technique the expression of cyclooxygenase 2 (COX-2), prostaglandin E2 synthase (cPGES), prostaglandin F2α receptor (FP receptor) and nuclear factor Nrf2 was determined. Statistically the highest expression of COX-2, cPGES, and FP receptor was observed in LPS-activated macrophages. RAW 264.7 cells supplementation with ZnONP 100 nmol and 500 nmol and LPS activation resulted in repression of COX-2 and cPGES, and an increased expression of Nrf2 protein when compared to control. The results suggest an anti-inflammatory effect and activation of the antioxidant system by ZnONP in RAW 264.7 macrophages. It seems appropriate to conduct further research on the molecular mechanism of action of ZnONP in eukaryotic cells.

zinc-copper antagonism
Opis:
The role of copper in anti-inflammatory response includes several mechanisms. Antagonism between zinc (Zn) and copper (Cu) and proper balance between the two elements in the organism may affect the course of inflammatory diseases. Copper is a component of Zn/Cu superoxide dismutase (Zn/Cu SOD) and other enzymes involved in the anti-inflammatory response of the organism. To investigate the serum copper level during inflammation and diseases, numerous researches were conducted. Copper deficiency or copper intoxication may lead to biological consequences. Copper deficiency may be caused by various factors, one of them is excessive zinc supplementation. The aim of the study was to investigate the alterations in the serum copper level after 2-week zinc oxide nanoparticles (NPs-ZnO) administration. The second aim was to investigate serum copper level alterations after 2-week NPs-ZnO and single ketoprofen administration. The inflammatory state was induced in each group by the carrageenan injection at the 15th day of the experiment. The results indicate for the decrease in serum copper level in group receiving NPs-ZnO compared to control. Moreover, in groups receiving NPs-ZnO as well as ketoprofen, a decrease in serum copper level was observed. We may conclude that NPs-ZnO administration and also ketoprofen administration acts as anti-inflammatory agents and may induce a decrease in serum copper level.

Opis:
Alterations in membrane lipid composition, particularly fatty acids content is known to result in functional and structural changes. Dietary lipids and physical activity or stress play an important role in this change. It was of interest to study the influence of swimming in different temperatures on the content of fatty acids in the phospholipids of the erythrocyte membranes of rats. Our research demonstrated a significant influence of swimming on the content of fatty acids in the phospholipids of the erythrocyte membranes of rats. These changes of fatty acids, particularly the decrease of arachidonic acid and significant increase of saturated fatty acids in the phospholipids of the erythrocyte membranes in swimming rats may be induced by oxygen radicals generated in different kinds of stress.
