Abstract
Nutrients consumed by mothers during pregnancy and lactation can exert permanent effects upon infant developing tissues, which could represent an important risk factor for diseases during adulthood. One of the important nutrients that contributes to regulating the cell cycle and tissue development and functionality is the trace element selenium (Se). Maternal Se requirements increase during gestation and lactation. Se performs its biological action by forming part of 25 selenoproteins, most of which have antioxidant properties, such as glutathione peroxidases (GPxs) and selenoprotein P (SELENOP). These are also related to endocrine regulation, appetite, growth and energy homeostasis. In experimental studies, it has been found that low dietary maternal Se supply leads to an important oxidative disruption in dams and in their progeny. This oxidative stress deeply affects gestational parameters, and leads to intrauterine growth retardation and abnormal development of tissues, which is related to endocrine metabolic imbalance. Childhood pathologies related to oxidative stress during pregnancy and/or lactation, leading to metabolic programing disorders like fetal alcohol spectrum disorders (FASD), have been associated with a low maternal Se status and intrauterine growth retardation. In this context, Se supplementation therapy to alcoholic dams avoids growth retardation, hepatic oxidation and improves gestational and breastfeeding parameters in FASD pups. This review is focused on the important role that Se plays during intrauterine and breastfeeding development, in order to highlight it as a marker and/or a nutritional strategy to avoid diverse fetal programming disorders related to oxidative stress.

Assessment of In Vitro Bioaccessibility and In Vivo Oral Bioavailability as Complementary Tools to Better Understand the Effect of Cooking on Methylmercury, Arsenic, and Selenium in Tuna.

Abstract
Fish consumption is the main exposure pathway of the neurotoxicant methylmercury (MeHg) in humans. The risk associated with exposure to MeHg may be modified by its interactions with selenium (Se) and arsenic (As). In vitro bioaccessibility studies have demonstrated that cooking the fish muscle decreases MeHg solubility markedly and, as a consequence, its potential absorption by the consumer. However, this phenomenon has yet to be validated by in vivo models. Our study aimed to test whether MeHg bioaccessibility can be used as a surrogate to assess the effect of cooking on MeHg in vivo availability. We fed pigs raw and cooked tuna meals and collected blood samples from catheters in the portal vein and carotid artery at: 0, 30, 60, 90, 120, 180, 240, 300, 360, 420, 480 and 540 min post-meal. In contrast to in vitro models, pig oral bioavailability of MeHg was not affected by cooking, although the MeHg kinetics of absorption was faster for the cooked meal than for the raw meal. We conclude that bioaccessibility should not be readily used as a direct surrogate for in vivo studies and that, in contrast with the in vitro results, the cooking of fish muscle did not decrease the exposure of the consumer to MeHg.

Abstract
Purpose The present research was designed to evaluate the toxicity of tellurium and its prevention by selenium on the pituitary gland in male Wistar rats. Methods 30 rats were used weighing 200–250 gm, and randomly divided them into five groups. Each group contained an equal number of animals. Group-1 was nominated as control group. Group-2 received an intraperitoneal dose of selenium 0.3 mg per kg body wt. Group-3 was administered with tellurium 4.15 mg per kg body wt. Group-4 was given low-dose (L) of both selenium 0.15 and tellurium 2.075, Group-5 was given High-dose (H) of both selenium 0.3 and tellurium 4.15 mg/kg body wt. orally once in a day. After 15 days of dosing, the behavioral activities- motor co-ordination rotarod and grip strength test were measured. On 16th-day animals were sacrificed and activity of LPO, GSH, caspase-3, caspase-9, GPx, GR, SOD, catalase, and AChE were performed on the pituitary gland as per standard method reported. Results Se when given together with Te, significantly protects the motor coordination up to 32.5%, and also protects the grip strength up to 75% in group 4 and 5 respectively as compared to group- 3. Se + Te treatment protects the activity of TBARS up to 48.68% and GSH is 58%. As compared to control, it protects caspase-3 up to 118% and caspase-9 up to 83%. The level of AChE was also observed to be modulated by the administration of Se in Group- 4 and 5. Se + Te protected AChE up to 28.6%. Similar findings were observed for the biochemical activities of GPx (140% protection), SOD (458%), GR (159%), and catalase (95%) activities that were protected significantly Se + Te in Group- 4 and 5. Conclusion Selenium dose-dependently protects behavioral activities. It also protects apoptosis, oxidative stress, and AChE activities in the pituitary gland.

Oxidative Stress Parameters in the Liver of Growing Male Rats Receiving Various Alcoholic Beverages. Nutrients 2020; 12:nu12010158. [PMID: 31935882 PMCID: PMC7019817 DOI: 10.3390/nu12010158] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2019] [Revised: 01/02/2020] [Accepted: 01/03/2020] [Indexed: 02/07/2023] Open
Abstract
Typical alcohol consumption begins in the adolescence period, increasing the risk of alcoholic liver disease (ALD) in adolescents and young adults, and while the pathophysiology of ALD is still not completely understood, it is believed that oxidative stress may be the major contributor that initiates and promotes the progression of liver damage. The aim of the present study was to assess the influence of alcohol consumption on the markers of oxidative stress and liver inflammation in the animal model of prolonged alcohol consumption in adolescents using various alcoholic beverages. In a homogenic group of 24 male Wistar rats (4 groups—6 animals per group), since 30th day of life, in order to mimic the alcohol consumption since adolescence, animals received (1) no alcoholic beverage (control group), (2) ethanol solution, (3) red wine, or (4) beer (experimental groups) for 6 weeks. Afterwards, the activities of alcohol dehydrogenase (ADH), alanine aminotransferase (ALT), and aspartate aminotransferase (AST), as well as levels of cytochrome P450-2E1 (CYP2E1), thiobarbituric acid-reactive substances (TBARS), protein carbonyl groups, tumor necrosis factor-α (TNF-α), and interleukine-10 (IL-10) were measured in liver homogenates. The difference between studied groups was observed for CYP2E1 and protein carbonyl groups levels (increased levels for animals receiving beer compared with control group), as well as for ALT activity (decreased activity for animals receiving beer compared with other experimental groups) (p < 0.05). The results suggested that some components of beer, other than ethanol, are responsible for its influence on the markers of oxidative stress and liver inflammation observed in the animal model of prolonged alcohol consumption in adolescents. Taking this into account, beer consumption in adolescents, which is a serious public health issue, should be assessed in further studies to broaden the knowledge of the progression of liver damage caused by alcohol consumption in this group.

Abstract
The World Health Organization (WHO) reported that alcohol consumption is a serious problem in adolescents. The aim of the study was to assess the influence of the time of exposure of various alcoholic beverages on body mass as well as on select parameters of liver antioxidant defense in adolescent Wistar rats. Thirty-day-old animals were divided into 12 groups (six animals in each): control and groups receiving various beverages containing 10% of alcohol (ethanol, red wine, beer), observed for two, four, and six weeks. The body weight gain and energy supply were analyzed for body mass assessment. The catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase, transferase (GST), reductase activities, total antioxidant status, and glutathione level (GSH) were analyzed, for a liver antioxidant defense assessment. Group receiving red wine was characterized by the highest alcohol intake, lowest dietary intake, and highest total energy supply (p < 0.05). However, this did not influence body weight gain (p > 0.05). Reduced diet intake in groups receiving alcohol was counterbalanced by its energy value. Therefore, the energy supply was not lower than for the control (p > 0.05). Alcohol consumption and the experiment duration influenced CAT, SOD, and GST activities and GSH level. Alcohol consumption may influence hepatic antioxidant defense in adolescent male rats, but without influence on body weight gain.

Abstract
There are disorders in children, covered by the umbrella term “fetal alcohol spectrum disorder” (FASD), that occur as result of alcohol consumption during pregnancy and lactation. They appear, at least in part, to be related to the oxidative stress generated by ethanol. Ethanol metabolism generates reactive oxygen species and depletes the antioxidant molecule glutathione (GSH), leading to oxidative stress and lipid and protein damage, which are related to growth retardation and neurotoxicity, thereby increasing the incidence of FASD. Furthermore, prenatal and postnatal exposure to ethanol in dams, as well as increasing oxidation in offspring, causes malnutrition of several micronutrients such as the antioxidant folic acid and selenium (Se), affecting their metabolism and bodily distribution. Although abstinence from alcohol is the only way to prevent FASD, it is possible to reduce its harmful effects with a maternal dietary antioxidant therapy. In this review, folic acid and Se have been chosen to be analyzed as antioxidant intervention systems related to FASD because, like ethanol, they act on the methionine metabolic cycle, being related to the endogenous antioxidants GSH and glutathione peroxidase. Moreover, several birth defects are related to poor folate and Se status.

Abstract
AIM The fetal alcohol exposition during pregnancy leads to different disorders in offspring, related to the oxidative stress generated by alcohol. It is well-documented that there is an impairment of the antioxidant selenoprotein Glutathione peroxidase (GPx) activity in ethanol offspring during the embryo period, although no-one has described Selenium (Se) status. The aim is to analyze for the first time Se deposits in vivo and Se's biological implication in embryos and placenta after alcohol exposure and in offspring whose mothers continued to drink ethanol during lactation. MATERIALS AND METHODS Se deposits, GPx and glutathione reductase (GR) activity, lipid and protein oxidation and the expression of GPx1 were measured in placenta and liver of both embryos (E-19) and breastfeeding pups (L-21) in control and ethanol groups (20% v/v). KEY FINDINGS Ethanol consumption decreased Se deposits, GPx activity and GPx1 expression, while increasing biomolecular oxidation in placenta and in the liver of E-19 and L-21. The GR/GPx ratio decreased in placenta and in E-19, together with an increase in lipid oxidation, while increased in the liver of L-21 pups with protein oxidation. Ethanol also decreased the GPx1 expression/GPx activity ratio in the liver of E-19 and L-21, indicating that alcohol decreases GPx activity by both depleting Se deposits and promoting GPx inactivation. In placenta GPx activity is proportional to the GPx1 expression found, so the ethanol affects GPx activity in offspring more than in dams. SIGNIFICANCE Therefore, Se supplementation therapy in dams could contribute as an interesting antioxidant that prevents fetal alcohol syndrome.

Abstract
PURPOSE Selenium (Se) has a dual role in metabolic syndrome (MS) development as it has an antioxidant action against both "good" and "bad" reactive oxygen species. This study evaluates Se body profile in dams which present MS during gestation and lactation, in order to elucidate a normal dietary Se's implication in this pathology. METHOD Rats were randomized into control (C) and fructose (F) groups. The rich fructose diet (65 %) during gestation and lactation periods induced MS in dams. Se body distribution was determined by atomic absorption spectrophotometry, and the hepatic activity of the four antioxidant enzymes and the bimolecular oxidation were determined by spectrophotometry. The cardiac activity was monitored using the indirect tail occlusion method. Lipid and glucidic profile was also analyzed. RESULTS Despite the fact that the diet supplied has 0.1 ppm of Se, the minimal dietary requirement for rats, F dams ate less amount of food, and therefore, they had lower Se retention. However, they had normal levels of Se in serum and milk. Dams with MS had Se depletion in heart and muscle joint to hypertension and a lower heart rate, and Se repletion in liver and kidney. Despite the increase in hepatic glutathione peroxidase (GPx) and catalase activity found, lipid oxidation occurred-probably because superoxide dismutase activity was diminished. In heart, the activity and expression of the selenoprotein GPx1 were decreased. CONCLUSION With these results, it is not possible to elucidate whether a dietary Se supplementation or a Se-restricted diet are good for MS; because despite the fact that GPx activity is increased in liver, it is also found, for the first time, that heart Se deposits are significantly decreased during MS.

Abstract
Alcoholic cardiomyopathy is the damage caused to the heart muscles due to high level of alcohol consumption resulting in enlargement and inflammation of the heart. Selenium is an important trace element that is beneficial to human health. Selenium protects the cells by preventing the formation of free radicals in the body. In the present study, protein mediated synthesis of SeNPs was investigated. Two different sizes of SeNPs were synthesized using BSA and keratin. The synthesized SeNPs were characterized by scanning electron microscopy (SEM) with elemental composition analysis Energy Dispersive X-ray spectroscopy(EDX) and X-ray diffraction (XRD). This study demonstrates the in vitro and in vivo antioxidative effects of sodium selenite and SeNPs. Further selenium and SeNPs were evaluated for their ability to protect against 1% ethanol induced oxidative stress in H9C2 cell line. The selenium and SeNPs were found to reduce the 1% ethanol-induced oxidative damage through scavenging intracellular reactive oxygen species. The selenium and SeNPs could also prevent pericardial edema induced ethanol treatment and reduced apoptosis and cell death in zebrafish embryos. The results indicate that selenium and SeNPs could potentially be used as an additive in alcoholic beverage industry to control the cardiomyopathy.

Abstract
BACKGROUND Binge drinking (BD) is the most common ethanol (EtOH) intake consumption model among teenagers, but little is known about its effects on the liver. During its hepatic metabolism, acute alcohol exposure produces a great amount of reactive oxygen species which contributes to alcohol-induced liver injury. Selenium (Se) plays a key role in antioxidant defense as it forms part of selenoproteins, such as the antioxidant glutathione peroxidases (GPxs) or the selenoprotein P (SelP), synthesized mainly in liver. Chronic EtOH consumption decreases both Se deposits and this tissue's antioxidant activity. METHODS Two BD administration routes (oral and intraperitoneal) were used in adolescent rats to analyze Se homeostasis; the main hepatic selenoproteins' expression: GPx1, GPx4, and SelP, and their biological roles related to oxidation. Their relationship with inflammatory processes was also determined by analyzing the expression of the transcriptional factor nuclear factor-kappa beta (NF-κB). RESULTS It has been demonstrated for the first time that BD in adolescents alters Se homeostasis regardless of the administration route employed, despite the fact that the BD oral group ingested less Se in diet. This decrease of Se in serum and liver is directly related to a decrease in serum GPx3 and hepatic GPx1 activity, contributing to the oxidative imbalance found. The depletion of Se detected in liver affects GPx1 expression and, surprisingly, GPx4 expression. This could be related to the lower expression of the transcriptional factor NF-κB in the liver, a key player in the regulation of inflammatory processes. CONCLUSIONS Due to the above, and to find whether a Se supplementation therapy improves these situations, it would be interesting to explore in more depth the relationship between Se, the high oxidation found, and the depressed immune response reported in BD adolescents.

Abstract
This study describes the effects of selenium (Se) deficiency on the messenger ribonucleic acid (mRNA) expression of 25 selenoproteins (Sels) (including glutathione peroxidases (GPx1-GPx4), thioredoxin reductases (TrxR1-TrxR3), iodothyronine deiodinases (ID1-ID3), selenophosphate synthetase 2 (SPS2), 15-kDa Sel (Sel15), SelH, SelI, SelK, SelM, Sepn1, SelO, Sepx, Selpb, SelS, SelT, SelW, Sepp1, and SelU in the adipose tissues (subcutaneous adipose, visceral adipose, and articular adipose) of chickens. One hundred and fifty 1-day-old chickens were randomly assigned to two groups of 75 each and were fed a low-Se diet (0.032 mg/kg Se) or a control diet (0.282 mg/kg Se). The expression levels of 25 Sel mRNAs were determined on days 35, 45, and 55 from three parts (subcutaneous adipose, visceral adipose, and articular adipose) of the chicken adipose tissues. The results showed that the expression levels of the 25 Sel mRNAs were significantly lower (P < 0.05) in the low-selenium group than in the control group. In addition, the Sel mRNA expression levels in the three adipose tissues were observed to decrease in a time-dependent manner with increasing feeding time.
