    Opis:
    Free radicals containing one or more unpaired electrons have considerable reactivity. Those radicals derived from oxygen represent the most important class of such species. Free radicals generated in organism are reactive oxygen species (ROS) and reactive nitrogen species (RNS) well recognised for playing a dual role as both deleterious and beneficial species. The cumulative production of ROS/RNS is termed oxidative stress and were discovered in pathomechanism of many of diseases. It was observed that in medium concentration ROS and RNS are play a role in inflammation, apoptosis and as secondary messengers in intracellular signalling cascades.

    biochemistry of zinc
    zinc functions
    Opis:
    Zinc is a metallic element, of symbol Zn and atomic number 30, that is placed in the group 12 of the periodic table. As an essential trace element, zinc is required to support human biochemical processes. It is found in nearly 200 specific enzymes in the living organisms, and it also serves as structural cofactor for many cellular proteins. [1] Zinc may exert pleiotropic effects in organism; for that, deficits of cellular zinc content can have catastrophic consequences and are linked to major pathophysiology, such as diabetes, stroke and malformations of brain function [2]. The complexity and importance of zinc homeostasis is reflected by the large variety and number of zinc-related proteins found in almost every cell compartment; for example, this biometal is transported through ZnT (Zn2+ transporter) family and ZIP family, proteins that are completely dedicated to zinc transport [2]. It is also noticeable, that between three and ten percent of all protein products of genes in mammalian genomes bind zinc, which is essential for their folding, activity or conformational change [2].

    Opis:
    Metabolism of polyunsaturated fatty acids results in biosynthesis of mediators with different physiological effects. These metabolites include prostaglandins, prostacyclins, isoprostanes and others that are important signalling molecules and regulate a variety of physiological and pathophysiological processes including inflammation. Prostaglandins and isoprostanes are produced by either non-enzymatic lipid peroxidation or by enzyme-induced peroxidation (cyclooxygenases and lipoxygenases). They are used as biomarkers of oxidative stress. The aim of our study was to assess the effect of eicosapentaenoic acid (EPA) supplementation with added benzo(a)pyrene (BaP) on HepG2 cells by using a UHPLC/MS-TOF method. This rapid and simple method was developed for the identification, separation and quantification of 8-iPGF3α, PGF3α, 8-isoPGF2α and 5-iPF2α in cultured cells. The UHPLC/MS-TOF method was validated. The calculated limit of detection was in the range of 0.16-0.50 ng/mL, precision (% RSD): 1.2-2.1% and recoveries better than 88%. This method empowered qualitative and quantitative analysis of the selected individual prostaglandins derived from arachidonic acid and eicosapentaenoic acid from cell extracts.

    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.

    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:
    Metal responsive transcription factor 1 (MTF-1) is a zinc dependent transcription factor which is involved in the regulation of intracellular signaling pathways. MTF-1 regulates the expression of two streams of genes functioning in metal homeostasis and anti-oxidative response. MTF-1 acts in the process of binding of toxic metal ions in the cell, due to the activation of the expression of metallothioneins (MTs). Additionally, MTF-1 regulates transcription of genes involved in the sequestration of zinc and its intracellular transport. Disruption of zinc and MT homeostasis has an indispensable influence on the development of several pathological states. Moreover, by increasing MT activity, MTF-1 can effectively protect cells from oxidative and hypoxic stresses. The mechanism of MTF-1 action in cells includes the regulation of the proper immune response through activation/repression of anti- and pro-inflammatory cytokines. MTF-1 function in immune response is related to nuclear factor-κB (NF-κB) activity. Synthesis of insulin is also related to the activity of this transcription factor and zinc balance. Insulin transport also depends on zinc. In pancreatic β-cells, several types of the zinc transporters are found. Zinc transporters coordinated action is crucial for the synthesis and secretion of insulin. Disturbances in the regulation of signaling pathways connected with MTF-1 function can entail further alterations in zinc intracellular status and this growing imbalance can promote the pathophysiology of degenerative disorders.

    Opis:
    The purpose of this study was to analyze the indolic, phenolic, and fatty acid content and antioxidant activity of garlic sprouts growing in the dark and in the daylight. The pro- or anti-inflammatory properties of the garlic sprout extract were investigated by evaluating the cyclooxygenase-2 (COX-2), prostaglandin E synthase (cPGES), glutathione S transferase (GSTM1), nuclear factor NF-κB, peroxisome proliferator-activated receptors (PPARs), and aryl hydrocarbon receptor (AhR) protein levels in the RAW 264.7 cells activated with lipopolysaccharide (LPS). The highest amount of total indolic (73.56 mg/100 g f.w.) and phenolic compounds (36.23 mg/100 g f.w.) was detected in garlic sprouts grown in the daylight. Studies on antioxidant activity (the FRAP and DPPH method) of garlic sprouts showed that this activity is significantly higher for sprouts grown in full access to light when compared to those grown in the dark. In garlic sprout extracts, α-linolenic acid (ALA) was found to be in greater amount. COX-2 and cPGES level was lower when compared to LPS alone activated cells. After garlic extract treatment, higher level of GSTM1, PPARΥ, cytosolic p50 and p65 protein, as well as a lower NF-ĸB p50/p65 activity was noted in the RAW 264.7 cells which suggested PPARs and AhR transrepression mechanism of NF-ĸB signalling. The obtained results indicate Allium sativum sprouts are a rich source of n-3 fatty acids, indolic and phenolic compounds characterized by anti-inflammatory and antioxidative activity, which may support their high therapeutic and dietary potential.

    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.

    Opis:
    Mania is a psychiatric disorder which may occur alternately with depression as a bipolar disorder, or much less often as an individual disease. It might be accompanied by other disorders, i.e. schizophrenia, dementia or withdrawal syndrome. Only a few effective drugs are used for the treatment of mania. Patients suffering from bipolar disorder are treated with mood-stabilizing drugs, administered during the course of the disease, and drugs that are implemented when mania or depression episodes occur. Some studies report effectiveness of anticonvulsant drugs in the cessation of mania, thus in our study we assessed the effectiveness of pregabalin in a mouse model of mania induced by administration of metylphenidate (5 mg/kg; s.c). Pregabalin was tested in the forced swim test (75 mg/kg, 100 mg/kg; i.p.) and the elevated plus maze test (75 mg/kg; i.p.) to assess its antidepressant-like and anxiolytic-like properties, respectively. In the elevated plus maze in MPH-treated mice pregabalin significantly reduced time spent in open arms (p<0.001 vs. MPH-treated control). In the forced swim test MPH compared to vehicle significantly (p<0.001) reduced duration of immobility. In MPH-treated mice pregabalin partially reversed this effect of MPH. This effect was significant only for the dose of 75 mg/ kg (p<0.05). In the rotarod test neither MPH, nor its combination with pregabalin (75 mg/kg; 100 mg/kg) influenced motor coordination of mice at any speed tested. To conclude our study revealed that pregabalin might reverse manic-like action of MPH related to hyperlocomotion, which may indicate for its possible effectiveness in mania episodes.

    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:
    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.
