Abstract Marine collagen peptides (MCPs) are natural products prepared by hydrolyzing marine collagen protein through a variety of chemical methods or enzymes. MCPs have a range of structures and biological activities and are widely present in marine species. MCPs also have a small molecular weight, are easily modified, and absorbed by the body. These properties have attracted great interest from researchers studying antioxidant, anti-tumor, and anti-aging activities. MCPs of specific molecular weights have significant anti-tumor activity and no toxic side effects. Thus, MCPs have the potential use as anti-cancer adjuvant drugs.

Abstract Background: Trigonella foenum-graecum Linn. has been extensively used for medicinal purposes. The current study deals with in vitro and in vivo correlation of free radical quenching activity and anticancer potential of seed extracts of Trigonella. Materials and methods: Antioxidant activity was evaluated against DPPH, NO and ABTS via in vitro radical scavenging assay. Cytotoxicity effect of Trigonella seed extract was studied in human embryonic kidney HEK 293 cell line by alamar blue assay. In vivo antioxidant activity in Swiss albino mice model was assessed by studying endogenous antioxidant enzymes such as GSH, GPx, SOD and LPO. Antitumor effect was observed by studying parameters… More >

Abstract In our previous study, silver nanoparticles were prepared using AgNO₃ and carboxymethyl chitosan (CMCS) which is commercially available with solar irradiation. In this study, the efficacy and safety of silver nanoparticles prepared by this method were evaluated for healing wounds in rats with diabetes. We also attempted to determine the underlying mechanism and influencing factors of the silver nanomaterial preparation method. Compared with growth factors, silver nanoparticles exhibit better healing effects for rats with diabetes. No remnant silver ions were detected in the major organs of these rats after the application of silver nanoparticles. Silver nanoparticles… More >

Abstract This work aims to determine the phytochemical characterization of the pericarp of Chamaedorea radicalis Mart. fruit as a non-timber product with potential to obtain phytochemicals with potential applications in the industry. Fruit from C. radicalis were grouped in four ripening stages named as S1, S2, S3 and S4, according to maturity; S1 the most unripe stage and S4 the completely ripe stage. Determinations of total phenolic compounds, free radical scavenging activities and total flavonoid contents using spectrophotometric methods were done. Also, the tentative identification of phytochemicals during fruit ripening was done using UPLC-MS-MS. Total phenolic compound (TPC)… More >

Abstract An increased interest in the antioxidant effects of medicinal plants has developed in recent years. Identifying antioxidant compounds present in medicinal plants and elucidating the mechanism by which they prevent oxidation have been the focus of the research community. We performed a systematic and exhaustive review aimed at analyzing the available data regarding the beneficial effects of secondary metabolites in plants. The result of this review is presented as a description of free radicals, as well as cellular and physiological oxidative stress, is provided. The origin and source of antioxidant compounds, and the cellular and More >

Abstract The species Rhaphiodon echinus, known as betonica or creeping mint, is considered an infesting plant species, typical of the caatinga biome. Morphoanatomy is a very important tool to study the structure of plants, both its external and internal morphology, opening the knowledge about the production of secondary metabolites. These compounds are of great importance for scientific research, which may present themselves as the best antioxidants. Taking into account a lack of data in the literature on the essential oil of R. echinus, this study aimed to demonstrate its antioxidant activity and toxicity. In order to test this… More >

Abstract Alcohol hangover (AH) is defined as the temporary state after alcohol binge-like drinking, starting when EtOH is absent in plasma. Results from our laboratory have shown behavioral impairments and mitochondrial dysfunction in an experimental model of AH in mice. Our model consisted in a single i.p. injection of EtOH (3.8 g/kg BW) or saline solution in male and female mice, sacrificing the animals 6 hours after injection. Motor and affective behavior together with mitochondrial function and free radical production were evaluated in brain cortex and cerebellum during AH. Results showed that hangover animals exhibited a… More >

Abstract The flower of Butea monosperma (Lam.) (Fabaceae) has been used in traditional Indian medicine in the treatment of many ailments including liver disorders. To understand the pharmacological basis of its beneficial effects, the extracts of dried flowers in water, methanol, butanol, ethyl acetate and acetone were evaluated for free radical scavenging and pro-apoptotic activities in cell cultures (human hepatoma Huh-7 cell line and immortalized AML-12 mouse hepatocytes). Butrin and butein -the active constituents of flower extracts- were used as reference molecules. The levels of cell injury markers like lactate dehydrogenase, glutathione and lipid peroxidation and primary… More >
