Opis:
Kadm (Cd) jest jednym z głównych zanieczyszczeń środowiska, co stanowi poważne zagrożenie dla zdrowia ludzi i zwierząt. Do tej pory opisano różne mechanizmy toksycznego działania kadmu - indukcja stresu oksydacyjnego jest jednym z nich. W obecności kadmu wzrasta w komórkach poziom reaktywnych form tlenu, takich jak: anionorodnik ponadtlenkowy, rodnik hydroksylowy czy nadtlenek wodoru. Kadm powoduje także obniżenie statusu tiolowego i zaburzenia w komórkowym systemie antyoksydacyjnym. Celem niniejszej pracy było zbadanie wpływu jonów kadmu na wzrost i przeżywalność drożdży oraz sprawdzenie, czy dodatek antyoksydantów do pożywki uchroni komórki drożdży Saccharomyces cerevisiae przed toksycznym działaniem kadmu. Zastosowano dwa szczepy drożdży: szczep dziki SP4 i szczep DSCD1-1C (Δsod1 mutant) pozbawiony CuZnSOD. Komórki drożdży hodowano na standardowej pożywce YPG, zawierającej dodatkowo jony kadmu i różne stężenia antyoksydantów (m.in. askorbinian, cysteinę, glutation, DTT, N-acetylocysteinę, Tempo, Tempol i Trolox). Stwierdzono niekorzystne działanie kadmu na oba szczepy drożdży - komórki drożdży pozbawione CuZnSOD wykazują znacznie większą nadwrażliwość (10 μM stężenie jonów kadmu powoduje całkowite zahamowanie ich wzrostu); podczas gdy szczep dziki jest wrażliwy przy wyższych stężeniach kadmu (25-50 μM). Stwierdzono ponadto, że tylko antyoksydanty tiolowe znoszą toksyczne działanie kadmu na komórki drożdży.
Cadmium (Cd) is the main environmental pollutant, which presents a serious threat to the health of people and animals. Up to the present time, different mechanisms of the toxic action of cadmium have been described - induction of oxidative stress is one of them. Exposure to cadmium ions can intensify the production of reactive oxygen species (ROS) such as: superoxide radicals, hydroxyl radicals or hydrogen peroxide. Cadmium also causes the decrease in thiol status and the disruption of the cellular antioxidant system. The aim of this study was to determine the effect of Cd2+ on growth and survival rates of yeast cells, and to check whether supplementing media with antioxidants protects Saccharomyces cerevisiae yeast cells from toxic action of cadmium. Two yeast strains were used: wild-type SP4 and strain DSCD1-1C (Δsod1 mutant) lacking Cu, Zn-superoxide dismutase. Yeast cells were grown in standard UPD medium, involving cadmium ions and various concentrations of antioxidants (ascorbate, cysteine, glutathione, dithiotreitol, N-acetylcysteine, Tempo, Tempol and Trolox). The negative effect of cadmium was found in both yeast strains - yeast cells lacking CuZnSOD show much higher sensitivity (cadmium at a concentration of 10 μM causes complete inhibition of their growth); at the same time, wild-type strain is sensitive to cadmium at higher concentrations (25-50 μM). Moreover, it was found, that only thiol antioxidants abolish toxic action of cadmium in yeast cells.

Opis:
Introduction. Oxidative stress induced by the generation of excess reactive oxygen species is one of the cause of atherosclerosis finally leading to coronary heart disease (CHD). Glutathione reductase (GR), a flavoprotein antioxidant enzyme, regenerates glutathione (GSH) from its oxidized form, which is essential for scavenging of hydrogen peroxide by glutathione peroxidase. The aim of this study was to analyze the activity of GR and GSH level in serum of patients with various stages of CHD. Materials and method. Sixty consecutive patients with diagnosis of stable angina (SA, n=20), unstable angina (UA, n=20) and non-fatal myocardial infarction (MI, n=20) together with 20 healthy control subjects were enrolled. Venous blood samples were collected just before the coronary catheterization procedure (in study patients). GR activities and GSH concentration was determined using commercially available colorimetric kits. Results. The highest GR activity and GSH serum level was noticed in UA patients. However, statistical evaluation showed that only glutathione reductase activity was significantly higher in serum obtained from myocardial infarction patients, compared to stable angina pectoris patients (19.52 ± 13.88 vs 11.63 ± 5.45 nmol/min/ml for MI and SA, respectively; p<0.048). There were no significant differences in GSH between the CHD patients and controls. Conclusion. The elevated activity of glutathione reductase in serum of patients with unstable angina pectoris and myocardial infarction suggests the role of antioxidant system acute coronary syndromes.

Opis:
Inflammation and oxidative stress have been reported in patients with chronic hepatitis C (CHC) infection, but their influence on ischemia-modified albumin (IMA) levels and diabetes prevalence remains unknown. Sixty-three CHC patients, 28 with diabetes, and 40 healthy controls were enrolled in the study. Circulating levels of oxidative stress markers [Nε-(carboxymethyl)lysine- advanced glycation end products (CML-AGEs) and advanced oxidation protein products-(AOPPs)], pro-inflammatory cytokines (interleukin-6, and tumor necrosis factor α), and high-sensitivity C-reactive protein (hsCRP) were assessed. Compared with the controls, the CHC patients with diabetes showed a significant increase in plasma concentrations of IMA, AOPPs, interleukin-6 and hsCRP (P < 0.05). The values of IMA and hsCRP were more elevated in patients with diabetes than without diabetes (both P < 0.01). The positive relationships were found between hsCRP and presence of diabetes, IMA (both P < 0.01) and AOPP levels (P < 0.05). CML-AGEs did not show any significant correlation with IMA, markers of inflammation and presence of diabetes. In conclusion, we have documented significant elevation in plasma levels of IMA and AOPPs in CHC patients. In addition, circulating IMA was associated with inflammation markers and diabetes prevalence. This observation suggests a relationship between IMA and inflammation in CHC patients with diabetes, which may represent one of the mechanisms involved in the accelerated atherosclerosis in this population.

Opis:
Serine proteases HtrA1 and HtrA2 are involved in cellular stress response and development of several diseases, including cancer. Our aim was to examine the involvement of the HtrA proteins in acute oxidative stress response induced in hamster kidney by estrogen treatment, and in nephrocarcinogenesis caused by prolonged estrogenization of male Syrian hamster. We used semi-quantitative RT-PCR to estimate the HtrA1 and HtrA2 mRNA levels in kidney tissues, and Western blotting to monitor the amount of the HtrA proteins. Within the first five hours following estrogen administration both HtrA1 mRNA and the protein levels were increased significantly. No changes in the expression of HtrA2 were observed. This indicates that HtrA1 may be involved in the response against oxidative stress induced by estrogen treatment in hamster kidney. During prolonged estrogenization, a significant reduction of the HtrA1 mRNA and protein levels was observed after 6 months of estradiol treatment, while the expression of HtrA2 was significantly elevated starting from the third month. This suggests an involvement of the HtrA proteins in estrogen-induced nephrocarcinogenesis in hamster. Using fluorescence in situ hybridization we localized the HtrA1 gene at the qb3-4 region of Syrian hamster chromosome 2, the region known to undergo a nonrandom deletion upon prolonged estrogenization. It is possible that the reduced level of HtrA1 expression is due to this chromosomal aberration. A full-length cDNA sequence of the hamster HtrA1 gene was obtained. It codes for a 50 kDa protein which has 98 and 96% identity with mouse and human counterparts, respectively.

Background. The influence of infection with two species of entomopathogenic nematodes of Steinernematidae family on the activity of superoxide dismutase (SOD) of the host was studied. Material and methods. Last instar larvae of Galleria mellonella were experimentally infected with Steinernema affinis and S. feltiae at 20 invasive juveniles per insect. At 6, 12, 18, 24 and 36 h after infection activity of SOD was determined in extracts from infected and control insects. Results. The activity of SOD decreased gradually in the controls during the experiment. The activity of enzyme was 2-4-times higher in insects from both infected groups than in the control. During the first 12 h of infection the activity of SOD in insects infected with S. feltiae was higher than in those infected with S. affinis, then the activity of enzyme in the insects of both infected groups stayed at a similar level. A significant decrease of SOD activity in infected was recorded in second day of the infection.

We investigated the effect of daunorubicin on glutathione content and activity of GSH-related enzymes in cultured normal and diabetic human fibroblasts. Cells were incubated with 4 μM daunorubicin (DNR) for 2 h followed by culture in drug-free medium for up to 72 h. Treatment of diabetic cells with the drug caused a time-dependent depletion of intracellular GSH and a decrease of the GSH to total glutathione ratio. GSH depletion was accompanied by apoptotic changes in morphology of the nucleus. Analysis of GSH-related enzymes showed a significant increase of the activities of Se-dependent and Se-independent peroxidases and glutathione S-transferase. In contrast, glutathione reductase activity was reduced by 50%. Significant differences between normal and diabetic cells exposed to DNR were observed in the level of GST and Se-dependent glutathione peroxidase activities. These findings indicated that daunorubicin efficiently affects the GSH antioxidant defense system both in normal and diabetic fibroblasts leading to disturbances in glutathione content as well as in the activity of GSH-related enzymes.

Quercetin, a member of the flavonoid family is a major antioxidant acquired in humans by food consumption, while Cadmium fluoride (CdF2) is one of the naturally occurring chemicals having adverse effects. The protective effect of quercetin on time dependent oxidative damage induced in mice liver by CdF2 was studied in the following groups of mice consisting of six mice each: (i) control group; (ii) mice treated with single i.p injection of 2 mg/kg bw CdF2 for 24 h; (iii) mice treated with single i.p injection of 2 mg/kg bw CdF2 for 48 h; (iv) mice treated with single i.p injection of quercetin (100 mg/kg bw); (v) mice treated with i.p injection of 100 mg/kg bw of quercetin followed by i.p injection of CdF2 (2 mg/kg bw) for 24 h; and (vi) mice treated with i.p injection of 100mg/kg bw of quercetin followed by CdF2 (2 mg/kg bw) for 48 h. Administration of quercetin two hours before CdF2 significantly reduced the biochemical alterations in reduced glutathione, ascorbic acid, lipid peroxidation, super oxide dismutase, catalase and total protein (p<0.05). Histopathology also showed the protective effect of quercetin. The livers treated with CdF2 were atrophic, markedly nodular, inflamed and necrotic. However, this effect was reduced to a minimum in the mice pre-treated for two hours with quercetin.

The lifespan of budding yeast cells is divided into two stages: reproductive and post-reproductive. The post-reproductive stage of the yeast's lifespan has never been characterized before. We have analyzed the influence of various mutations on the post-reproductive (PRLS) and replicative (RLS) lifespans. The results indicate that PRLS demonstrates an inverse relationship with RLS. The observed lack of differences in the total lifespan (TLS) (expressed in units of time) of strains differing up to five times in RLS (expressed in the number of daughters formed) suggests the necessity of revision of opinions concerning the use of yeast as a model organism of gerontology.

In this study, the cryoprotective effect of different doses of propolis (P) on bull semen, which has solid pharmacological properties thanks to its rich phenolic components, was investigated biochemically and physiologically. Semen samples were collected from Simmental breed bulls via the artificial vagina and pooled. After dividing into five groups, control (C: no additive) and four different P (200, 100, 50, and 25 μg/mL) groups, the final concentration was diluted to 16×106 per straw. Semen samples were equilibrated at 4°C for approximately 4 hours, then placed in French straws and frozen. After thawing, sperm motility and kinetic parameters, DNA integrity by single-cell gel electrophoresis, sperm abnormalities by liquid fixation, and lipid peroxidation levels by the colorimetric method was analyzed by Computer-Assisted Semen Analyzer. P added to the diluent showed no effect on motility and kinetic parameters at P25 and P50 (p>0.05), while P100 and P200 had a negative effect (p<0.001). The addition of P (25 and 50) showed a treatment effect on tail abnormality compared to C (p<0.05). Especially P50 had a positive effect on tail length, tail DNA, and tail movement, while P100 and P200 caused DNA damage (p<0.001). MDA levels increased in all P dose groups compared to C (p<0.001). This study has clearly demonstrated that P25 and P50 supplements could be used therapeutically to treat sperm tail abnormalities and prevent DNA damage in post-thawed bull sperm.

Opis:
Objectives A water pipe (hookah) is a tobacco smoking tool which is thought to be more harmless than a cigarette, and there are no adequate studies about its hazards to health. Water-pipe smoking is threatening health of the youth in the world today. The objective of this study has been to investigate the carbon monoxide (CO) levels in breath, examine the changes in pulmonary function tests (PFT) and to assess the change of the oxidative stress parameters in blood after smoking a water pipe. Material and Methods This study is a cross-sectional analytical study that has included 50 volunteers who smoke a water pipe and the control group of 50 volunteers who smoke neither a cigarette nor a water pipe. Carbon monoxide levels were measured in the breath and pulmonary function tests (PFTs) were performed before and after smoking a water pipe. Blood samples were taken from either the volunteer control group or water-pipe smokers group after smoking a water pipe for the purpose of evaluation of the parameters of oxidative stress. Results Carbon monoxide values were measured to be 8.08±7.4 ppm and 28.08±16.5 ppm before and after smoking a water pipe, respectively. This increment was found statistically significant. There were also significant reductions in PFTs after smoking a water pipe. Total oxidative status (TOS), total antioxidant status (TAS) and oxidative stress index (OSI) were found prominently higher after smoking a water pipe for the group of water-pipe smokers than for the control group. Conclusions This study has shown that water-pipe smoking leads to deterioration in pulmonary function and increases oxidative stress. To the best of our knowledge this study is the only one that has shown the effect of water-pipe smoking on oxidative stress. More studies must be planned to show the side effects of water-pipe habit and protective policies should be planned especially for young people in Europe.

Thioredoxin, with its redox-regulating and reactive oxygen species (ROS) scavenging activities, plays several important biologic roles both in intracellular and extracellular compartments. The purpose of this report was to quantify the relative expression of Trx in rat hippocampus following an oxidative stress-involving treatment such as kainic acid (KA) using real-time PCR and the 2-ΔΔCT method. The relative changes in expression of Trx mRNA in KA-treated and control animals were significantly different as 2.02 ± 0.77 and 1.0 ± 0.26, respectively ( P <0.05). Minimum and maximum n-fold changes in Trx expression in KA-treated and control animals were determined as (1.4-5.2) and (0.8-1.3), respectively. Thus, real-time PCR and the 2-ΔΔCT method for data analysis from real-time PCR were found to be an accurate and sensitive method for quantifying Trx mRNA levels.
