Introduction and aim. Single nucleotide variants (SNV) of the patatin‐like phospholipase domain‐containing protein 3 (PNP-LA3) gene play an important role in hepatic lipid remodeling and lipogenesis de novo, which is associated with the development of metabolically unhealthy obesity (MUO) and metabolic associated fatty liver disease (MAFLD). The aim of the study was to define the contribution of SNV PNPLA3 gene to the development of MUO, complicated by MAFLD in children. Material and methods. 200 obese children aged 6-18 years were examined. The main group (n=118) was represented by children with MUO. The control group (n=82) consolidated of children with metabolically healthy obesity (MHO). Whole genome sequencing (CeGat) was performed in 31 children of the main and 21 children of the control group. Results. Among obese children, 14 variants of SNV PNPLA3 (rs139051, rs34179073, rs2294918, rs139047, rs779127153, rs2076212, rs738409, rs738408, rs4823173, rs2072906, rs2076213, rs141106484, rs138736228) were identified, including SNV PNPLA3 g.44322818, not described in the dbSNP core database. The role of the following SNV PNPLA3 genotypes in the development of MUO complicated by MAFLD was revealed: rs738409 C/G (Relative risk (RR)=1.71); rs738408 C/T (RR=1.71); rs4823173 G/A (RR=1.57); rs2072906 A/G (RR=1.57) with Sensitivity (Se)=0.63 and Specificity (Sp)=0.72. Conclusion. The contribution to the development of MUO complicated by MAFLD in children is made by the linked association of genotypes: rs738409 C/G, rs738408 C/T, rs4823173 G/A and rs2072906 A/G out of 14 PNPLA3 SNVs diagnosed by us.

Opis:
Background: Non-alcoholic fatty liver disease (NAFLD) is one of the most common liver diseases, influenced by various risk factors associated with metabolic disorders. Currently there is no specific effective treatment for NAFLD. Probiotics have been extensively researched for their health benefit Probiotic Supplementation for NAFLD. Methods: A simple literature review was performed based on searches via PubMed, ScienceDirect and Google Scholar, using the keywords "probiotic," "microbiota," "non-alcoholic fatty liver disease," "metabolic disorder," and "therapy." Results: Research on the use of probiotics for NAFLD demonstrated improvement in liver function and histology. However, the literature is inconsistent regarding the probiotics’ influence on the NAFLD risk factors. Probiotics can be an alternative therapy for NAFLD through the ability to modulate the microbiota of the gastrointestinal tract. Conclusion: Probiotics can be an alternative therapy in NAFLD patients, however more extensive studies are needed to ensure the safety of this approach.

Opis:
Arsenic is a prevalent and pervasive environmental contaminant with varied amounts in drinking water. Arsenic exposure causes cancer, cardiovascular, liver, nerve, and ophthalmic diseases. The current study aimed to find the best conditions for eliminating arsenic from simulated wastewater and their effect on biomarkers of hepatic in mice. Adsorption tests including pH, contact duration, Al-kheriat dosage, and arsenic concentrations were evaluated. Seventy-two healthy albino mice (male) were accidentally allocated into nine groups (n = 8), the first group was considered as healthy control, the second group (AL-Kheriat), and other groups received AL-Kheriat and arsenic 25, 50, 75, 100, 125, 150 and 175 mg/kg, respectively. Next 10 days, the following were examined: LD50 level, ALP (alkaline phosphatase), ALT (alanine aminotransferase), and AST (aspartate aminotransferase), besides the histological condition of the liver. The results showed that the best time for arsenic removal was 4 hours, pH 8, Alkheriat dose 1 gram, and 50 ppm of pollutants. The level of alkaline phosphatase ALP, alanine transaminase ALT, and aspartate transaminase AST was increased to 150.96 (U/L), 143.1(U/L), and 32.8(U/L), respectively, in Al-Khriet and arsenic exposed population than the healthy control group, When the appropriate dose of Al-Khriet and arsenic mixture is used, it can aid in the selection of a safe way of disposing of the adsorbed residue. Additionally, it can serve as a low-cost rodent pesticide, increasing the commercial viability of this removal strategy.

Opis:
Introduction: The liver is involved in the metabolism of xenobiotics and their metabolites and it is vulnerable to oxidative damage. Hyperglycaemia is highly implicated in the progression of diabetes mellitus, and adversely affects the liver. Though, conventional hypoglycaemic drugs may be effective in reducing blood glucose, they do not appear to be effective in attenuating the progression of diabetes and its complications. Objective: This study evaluated the ameliorative effects of Anchomanes difformis on hyperglycaemia and hepatic injuries in type 2 diabetes. Methods: Type 2 diabetes was induced in male Wistar rats with a single intraperitoneal injection of streptozotocin (40 mg/kg BW) after two weeks of fructose (10%) administration. Aqueous extract of A. difformis (200 and 400 mg/kg BW) and glibenclamide (5 mg/kg BW) were administered orally for six weeks. Blood glucose concentrations were measured. Serum levels of liver dysfunction markers (ALT, AST, and ALP), total cholesterol, triglycerides, HDL- and LDL-cholesterol were investigated. Total protein, albumin, and globulin were also assessed. Antioxidant parameters: ORAC, GSH, GSSG, SOD, CAT and FRAP were evaluated in the liver while ORAC, FRAP and lipid peroxidation were determined in the serum. Histological examination of the liver tissue was carried out. Results: Treatment with aqueous extract of A. difformis significantly (p<0.05) reduced blood glucose and reversed steatosis in the diabetic-treated rats. The antioxidant status of diabetic-treated rats was significantly (p<0.05) improved. Serum levels of liver dysfunction markers were significantly (p<0.05) reduced in diabetic-treated rats. Conclusion: The findings in this study revealed that 400 mg/kgBW Anchomanes difformis was more effective than 200 mg/kg BW in ameliorating diabetes-induced hepatopathy, however, both doses of Anchomanes difformis demonstrated more antidiabetic ability than glibenclamide. Anchomanes difformis may be a novel and potential therapeutic agent in the management of diabetes and resulted hepatic injuries.

Neospora caninum is an important cause of abortion in dairy cattle. The general health of affected cows has not been investigated before. Therefore, the main objective of this study was to identify possible relationships between certain metabolic diseases and selected serum biochemical parameters in seropositive dairy cows against N. caninum antibodies in different stages of lactation. The study was carried out using 72 N. caninum seropositive cows and 61 seronegative dairy cows (control). Serum from all cows was tested to determine their N. caninum status (seropositive vs seronegative) using commercially available indirect enzyme-linked immunosorbent assay test kit (iELISA). In addition, serum biochemical parameters including beta-hydroxybutyrate (BHB), glucose, creatinine, blood urea nitrogen, total protein, albumin, alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine transaminase (ALT), lactate dehydrogenase (LDH) and gamma-glutamyltranspeptidase (GGT) were determined using routine laboratory methods. The stage of lactation was obtained at the time of sampling from farm records. Student independent t-test showed that there was a significant difference in the serum concentrations of BHB, AST, ALT, and LDH between seropositive and seronegative cows. There was no significant association between seropositivity and the stage of lactation. However, multivariable logistic regression analysis showed that there was a strong association between seropositivity and BHB concentrations. Results of this study indicate a possible relationship between N. caninum seropositivity and certain metabolic diseases such as ketosis and fatty liver syndrome in dairy cows.

Background and Aim: Fibrosis, which develops during the progression of liver damage, is the previous stage of cirrhosis. Carbon tetrachloride is one of the most commonly used hepatic toxins in experimental animal models of liver fibrosis. It was investigated the hepatoprotective effects of Tribulus terrestris, Ashwagandha and N-acetylcysteine in an experimental model of liver fibrosis induced by carbon tetrachloride in this study. Methods: Fifty Wistar rats were divided into five groups of 10 each, as follows: 1) control, 2) carbon tetrachloride, 3) carbon tetrachloride plus N-acetylcysteine, 4) carbon tetrachloride plus T. terrestris, and 5) carbon tetrachloride plus Ashwagandha group. At the end of 6 weeks, the rats were sacrificed, and serum and tissue samples were collected. Aspartate aminotransferase, alanine aminotransferase, gamma-glutamyl transpeptidase, malondialdehyde, NF-κB, collagen 1, nuclear factor erythroid-2-related factor 2, tumor necrosis factor-α were analyzed, and histopathological evaluation was performed. Results: There were no significant differences in serum aspartate aminotransferase and alanine aminotransferase levels of the N-acetylcysteine-treated group versus those in the T. terrestris- and Ashwagandha-treated groups (p>0.05). Liver malondialdehyde levels were lower in the N-acetylcysteine-, T. terrestris- and Ashwagandha-treated groups than in the carbon tetrachloride-administered group (p<0.001). There were differences between groups in NF-κB, collagen 1, nuclear factor erythroid-2-related factor 2 and tumor necrosis factor-α levels (p<0.05). Conclusions: In conclusion, T. terrestris, Ashwagandha and N-acetylcysteine had protective effects on the liver in this experimental fibrosis model. T.Terrestris was a little more effective than Ashwagandha in combating liver fibrosis.

Opis:
It was found that the main mechanisms of action of 4-hydroxyphenylpyruvatedioxygenase inhibitors are the development of tyrosinemia and alternations in thyroid hormone level as a result of hepatic enzyme induction. The main target organs of its action are the eyes, liver and thyroid gland. It was proved that the most adequate model for extrapolation of the effects of tyrosinemia on humans are mice, because their tyrosine aminotransferase activity level is similar to that in humans.

Purpose: To investigate the involvement of oxidative stress in Cadmium (Cd) induced alteration in the functional status of the liver. And to assess the efficacy of folic acid and vitamin B12 in preventing Cd-induced damage in the same. Materials and methods: The experiment was carried out for four weeks. For the experiment, 25 healthy male adult Wistar albino rats were randomly selected and were divided into five equal groups and treated as control, treated with Cd, supplemented with vitamin B12 and folic acid and in the combination of these two. After 28 days the liver function enzymes and oxidative stress parameters were measured. Results: Cd is the silent killer of the hepatic system through the induction of oxidative stress in male rats. From this investigation, it is evident that the folic acid+vitamin B12 possess significant hepatoprotective and antioxidant activity against Cd-induced hepatotoxicity in the rat model. In addition, results revealed that the folic acid alone and or in combination with vitamin B12 blunted the hepatotoxic effect significantly. Conclusions: Based on results obtained, it can be concluded that folic acid and vitamin B12 offer a protective effect in Cd-induced oxidative stress associated with hepatocellular injury. Folic acid and vitamin B12 can be considered as a potent natural antioxidant which has the capacity to provide protection against Cd-induced oxidative stress in the liver in rats. However, to elucidate the exact mechanism of this modulatory effect and to examine its potential therapeutic effects further studies are essential.

The addition of dried fruit had a positive effect on slowing down the formation of fat oxidation products. It was found that the selected additives had a significant effect on the tested parameters and caused, among others, increasing the oxidation-reduction potential in the analyzed products. Acerola (Malpighia emarginata) and wild rose (Rosa canina L.) turned out to be the additive that had the greatest impact on the physical parameters of the meat products tested.

Opis:
The research aim was to evaluate the levels of contamination with fluorine compounds in selected tissues of laying hens kept in a free range system in Central Pomerania (Poland) in relation to the distance from contaminant emission sources. The study covered 60, randomly selected, two-year-old laying hens on 6 farms. Fluorine levels in tissues of laying hens were determined with the potentiometric method using an ion-selective electrode from ORION. The results for the tissues and organs, such as pectoral muscles, livers and breastbones, were investigated with an analysis of variance, the Tukey’s test and linear correlation coefficients. The analyses revealed a higher mean fluorine compound content in the pectoral muscles, livers and breastbones of laying hens in zone 1, located 50 km to the west of the contaminant emission sources, than in zone 2, situated between 80 and 100 km to the west of the pollution sources. Fluorine compound levels in the pectoral muscles of zone 1 birds were almost twice as high in hens from experimental zone 2 (respectively: 1.835 mg kg-1 of DM and 0.978 mg kg-1 of DM). A statistically significantly higher average content of fluorine compounds (4.92 mg kg-1 of DM) was found in the liver of laying hens in zone 1, nearer to the sources of fluorine compounds emission compared to zone 2 (3.34 mg kg-1 of DM). The mean fluorine compounds content in the breastbones of hens in zone 1 was more than 4 times as high as the level of this element identified in the bones of hens kept in zone 2 (respectively: 765 mg kg-1 of DM and 183 mg kg-1 of DM). A significant positive correlation was confirmed between fluorine compound levels in the breastbones and pectoral muscles. The lower level of fluorine compounds in the examined tissues of laying hens in zone 2 could have been influenced by the dominant west and south wind, which limited the spread of pollution. This may also be due to the lower level of fluorine compounds in soil and feed for laying hens in this zone determined in previous studies. The study showed that the closer the sources of emissions of fluorine compounds, the more fluoride in hard tissues of hens’ bodies.
