Background: Medicinal plants together with their isolated bioactive compounds are known for their antioxidant properties which constitute therapeutic agents that are routinely employed in the treatment of liver diseases. Aims of the Study: The current study sought to explore the protective role of Warburgia salutaris and its isolated compound, iso-mukaadial acetate against carbon tetrachloride (CCl4)-induced hepatic injury. Methods: Thirty-five male Sprague Dawley rats were divided into seven groups of five animals each and injected with CCl4 to induce hepatic injury. Results: Treatment with the crude extract of W. salutaris and of iso-mukaadial acetate significantly reduced the levels of alkaline phosphatase, alanine and aspartate aminotransaminases, total bilirubin and malondialdehyde in a dose dependent manner, when compared to untreated groups. Liver histology revealed a reduction in hepatic necrosis and inflammation. Conclusion: The current investigation has demonstrated that W. salutaris extract and iso-mukaadial acetate could mitigate the acute liver injury inflicted by a hepatotoxic inducer in rats.

Abstract Background Titanium-based compounds have been incorporated as promising antineoplastic metals. In our previous studies, dithiophenolato titanium (IV) Complex "DBT" and its chitosan nanocomposite "DBT-CSNPs" were prepared and we showed that these compounds have antibacterial activities, cytotoxic, and have abilities to bind with DNA helixes. Therefore, in this study, we evaluated the LD50 values of dithiophenolato titanium (IV)-complex (DBT) and its high thermal stable chitosan nanoparticles (DBT-CSNPs). Then their therapeutic effects against liver injuries induced by carbon tetrachloride (CCl4) were assessed and compared with cisplatin treatment. Additionally, the anti-proliferative activity of DBT and DBT-CSNPs against human liver cancer (HepG2) cell lines through the analysis of the cell cycle was evaluated. Methods Nine groups of rats were prepared: normal, DBT, DBT-CSNPs, CSNPs, CCl4, CCl4-DBT, CCl4-DBT-CSNPs, CCl4-CSNPs and CCl4-cisplatin. Liver histopathology and the biochemical markers involving oxidative stress, apoptosis, liver and kidney functions, and lipid profile were determined. Results The results revealed that the treatment with DBT-CSNPs and DBT after CCl4 administration abolished liver damage since it reduced the apoptosis induced by CCl4 via the reduction of DNA fragmentation, Bax and caspase- 8 with an elevation of Bcl2 and Bcl2/Bax ratio. Also, these treatments caused nonsignificant changes in the markers of oxidative stress. Therefore, liver histopathology and functions, lipid profile, and kidney functions were improved. Cisplatin treatment reduced liver injury with a degree less than DBT-CSNPs and DBT, but it induced nephrotoxicity. Administration of DBT-CSNPs and DBT to healthy rats for 14 days has no adverse effect. Also, the results showed that DBT-CSNPs and DBT inhibited the proliferation of HepG2 cells by arresting cells in the G2/M phase and inducing cell death. Conclusion DBT-CSNPs and DBT have a therapeutic effect against CCl4-induced liver injuries via the reduction of apoptosis induced by CCl4. Moreover, both compounds have antineoplastic activities against the HepG2 cell line. In all cases, DBT-CSNPs have a greater effect due to their nanostructure. Therefore, both compounds can be used in the pharmacological fields, particularly DBT-CSNPs.

Research background. Amaranth flour (Amaranthus hypochondriacus) produces films with excellent barrier properties against water vapor, allowing food preservation, but the mechanical properties are poor versus to synthetic films. One strategy to improve these properties is the incorporation of nanoparticles. The particles can also serve as a vehicle for the addition of antioxidants agents into the films. The objective of this work was to optimize the formulation for preparation of amaranth flour films treated with antioxidant chia (Salvia hispanica L.) extract-loaded chitosan particles using RSM. Experimental approach. Chitosan nanoparticles with the extract were synthesized by ionic gelation, and the films were made by the casting method. Three independent variables were assigned: amaranth flour (4-6 %), glycerol (25-35 %), and chitosan nanoparticles loaded with the chia extract (0-0.75 %). We then evaluated the physical (thickness), mechanical (tensile strength, Young´s modulus, and elongation), barrier (water vapor permeability, moisture, and water solubility), and antioxidant properties of the films. The experimental results of the properties were analyzed using a Box-Behnken experimental design generating 15 runs with three replicates at the central point. Results and conclusions. Second and third order polynomial models were obtained from the ANOVA analysis of the evaluated responses, and high coefficients of determination were found (0.91-1.0). The films presented a water vapor permeability of 0.82-2.39·10-7 (g·mm)/(Pa·s·m2), a tensile strength of 0.33-1.63 MPa, and antioxidant activity of 2.24-5.65 %. The variables had different effects on the films: The glycerol negatively affected their properties, and the permeability values increased with amaranth flour concentration. The nanoparticles improved the mechanical, barrier, and antioxidant properties of the films versus films without nanosystems. The optimal formulation was 4 % amaranth flour, 25 % of glycerol, and 0.36 % of chitosan nanoparticles. The optimized films had better mechanical (1.62 MPa) properties, a low water vapor permeability value (0.91·10-7 (g·mm)/(Pa·s·m2)), and moderate antioxidant activity (6.43 %). Novelty and scientific contribution. The results show the effect of chitosan nanoparticles on the properties of amaranth flour films for the first time. The resulting equations are useful in the design of food packaging.

In this research, antimicrobial polysaccharide chitosan and natural extracts were used as surface coating of a plastic laminate with an integrated whey layer on the inside. The aim was to establish the biodegradable and active concept of packaging laminates. For this purpose, chitosan nanoparticles (CSNPs) with embedded rosemary or cinnamon extracts were synthesised and characterised. Additionally, a whey-based laminate was functionalised: i) chitosan macromolecular solution was applied as first layer and ii) cinnamon or rosemary extracts encapsulated in CSNPs were applied as upper layer (layer wise deposition). Such functionalised whey-based laminate was physicochemically characterized in terms of elemental surface composition, wettability, morphology and oxygen permeability. The antimicrobial activity was tested against Staphylococcus aureus, Escherichia coli, Aspergillus flavus and Penicillium verrucosum. The antioxidant properties were determined using the ABTS assay. It could be shown that after functionalization of the films with the above-mentioned strategy, the wettability was improved. Furthermore, such whey-based laminates still show excellent barrier properties, good antimicrobial activity and a remarkable antioxidative activity. In addition to the improved biodegradability, this type of lamination could also have a positive effect on the shelf-life of products packaged in such structured films.

Studies suggested antioxidant properties of the content of Syzygium aromaticum (clove). The study was conducted to obtain better understanding about the effect of clove on concentration of oxidative stress marker malondialdehyde (MDA) in liver and blood plasma of rat initially induced by carbon tetrachloride (CCl4); and whether blood plasma MDA level might represent liver condition. Experimental research was done using 20 Wistar rats classified into 5 treatment groups: (1) CCl4 - and clove-positive treatment after 3 days of clove treatment, (2) one day after, (3) alpha-tocopherol as positive control, (4) CCl4 only as negative control, and (5) normal control. Wills method was used for MDA concentration measurement. Liver MDA concentration were 0.0262 ± 0.0010 for group 1, 0.0214 ± 0.0047 group 2, 0 for group 3, 0.0077 ± 0.0094 group 4, and 0.0039 ± 0.0009 control group in nmol/mg protein (p = 0.001), whereas in the blood plasma it was 29.6032 ± 6.8021 for group 1, 26.1103 ± 3.6920 for group 2, 1.1612 ± 0.3555 for group 3, 1.4585 ± 1.4747 for group 4, and 2.4217 ± 1.2382 control group in nmol/mL (p = 0.001). Contrary to study in the past, no antioxidant properties were observed in treatment with dose 200 mg clove/kg body weight of rat. Such treatment increased MDA concentration and enhanced CCl4-induced damage in a time-dependent fashion. Strong correlation between MDA concentration in the liver and blood plasma (R = 0.97; p = 0.003) suggested blood plasma utilisation to represent hepatic MDA concentration or damage.

Essential oils are known to be a natural preservative due to their antimicrobial and antioxidant properties. The aim of this study was to evaluate an effect of thyme and cumin essential oils (EOs) in combination with air packaging and vacuum packaging on the shelf life of burgers from surimi and chicken meat. The study was conducted at 2°C for 27 days. We tested four groups of samples: (a) burgers in air package, (b) burgers with cumin and thyme EOs in air packaging, (c) burgers in vacuum packaging, and (d) burgers with cumin and thyme EOs in vacuum packaging. The greatest effect (P < 0.001) on the chemical and microbiological characteristics of the novel burgers displayed burgers with EOs of thyme and cumin packaged under vacuum. It can be explained by synergistic effect, which made it possible to extend the shelf life of the burgers. These results allowed us to suggest that surimi could be used as a basic ingredient in burgers production.
