Abstract:

Anthocyanins have been shown to possess specific antioxidant capacities, which may provide an underlying protective effect against many chronic diseases . Although the antioxidant capacity of anthocyanins has been well established, less is known about the extent to which specific anthocyanin composition affects total antioxidant capacity . The aim of the present study was to compare the antioxidant capacity of two different soft fruits, blackcurrant and grape, which have distinctly different anthocyanin profiles. The anthocyanin profiles of grape and blackcurrant were characterized by HPLC/MS

Abstract:

The benefits of consuming an antioxidant-rich diet have been discussed widely in the literature and includes anti-cancer effects. Antioxidant-rich, bioactive liquids can be created through extraction from plants. A liquid is not ideal as it may require refrigeration and may have a short shelf life. A bioactive powder is more convenient as it can be stored at room temperature for extended periods. The main aim of this study was to develop a drying method to produce a free flowing and non-sorbing bioactive powder in a repeatable and reproducible manner. Typical of many fruit juices and extracts

The aim of the present thesis was to assess the effect of the dietary supplementation of SOD-rich melon pulp concentrate (MPC) on oxidative status, inflammation and growth performance of post-weaning piglets and poultry. With this purpose three different trials were conducted: 1) MPC administration to no challenge or LPS-challenged post-weaning piglets to evaluate changes in the oxidative status and inflammation markers in blood together with growth performance; 2) MPC administration to broilers to evaluate growth performance and the incidence of both pododermatitis and cellulitis; 3) expressi

This dissertation is composed of 5 chapters detailing advances in the synthesis and post-modification of polymers using tetrazines. The research described herein conveys three new discoveries each of which should forge new fields of research concerning tetrazines in polymer chemistry, that is the use of tetrazines as chemical blowing agents in generating polymer foams, as agents for incorporating large concentrations of antioxidants into polymers, and their attachment to polymers, adding a photodegradable functional unit which alters the refractive index of the materials after degradation.

In vitro digestions mimicking gastric and intestinal enzymatic action in a chemical milieu have been used to examine the effects of digestion on polyphenol structure and function.

The consumption of these grains is mainly related to their organoleptic characteristics, but some researches demonstrate that they can also present nutritional differences compared to light-brown color rice grains.

Abstract:

The contamination of seafood with methylmercury (MeHg) is a global health issue, as MeHg is a well known neurotoxin. Since dietary nutrients may interact with MeHg toxicity, and oxidative stress is one of the primary mechanisms underlying MeHg neurotoxicity, we characterized dietary antioxidant-MeHg interactions. Firstly, we used an ethnobotanical study to confirm the antioxidant activity of Northern Labrador Tea, Rhododendron tomentosum ssp. subarcticum (Tea), for the Canadian Inuit, a population with elevated MeHg exposure. Secondly, we determined the ability of Tea to ameliorate MeHg-induce

O ferro é um elemento essencial para o crescimento e desenvolvimento das plantas, envolvido em processos metabólicos essenciais, como fotossíntese e respiração. Entretanto, quando livre e em excesso, pode gerar estresse oxidativo. A toxidez por excesso de ferro trata-se do maior problema nutricional em arroz alagado, sendo responsável por perdas na produtividade. Diversas estratégias para minimizar os efeitos tóxicos do ferro vêm sendo desenvolvidas, e entre elas, o uso de cultivares tolerantes é considerada a mais efetiva.

Uma das razões da menor fertilidade dos touros europeus criados em regiões tropicais em relação a touros Bos indicus é uma maior índice de estresse oxidativo provocado por uma maior produção de espécies reativas de oxigênio (ROS), não compensada pela proteção antioxidante. Por outro lado, sabe-se que a célula espermática é extremamente susceptível ao estresse oxidativo devido à alta quantidade de ácidos graxos poli-insaturados (PUFA) em sua membrana plasmática, o que, no entanto, é muito importante para que o espermatozoide seja fértil e resistente ao choque frio.

In 2006 all the AGP (antibiotic growth promoters) and some feed additives with growth promoting activities were banned (Cu, Zn). Since the first restrictive measures were taken, and due to the beginning of the negative consequences of the ban, numerous efforts have been done to find alternatives or replacement strategies to maintain pig growth performance and controlling enteric bacterial diseases.

Diversos estudos indicam que touros europeus (Bos taurus) apresentam uma maior susceptibilidade ao estresse térmico com um consequentemente aumento do estresse oxidativo. Este, por sua vez, leva a uma diminuição na qualidade espermática. O espermatozoide possui, fisiologicamente, uma grande quantidade de ácidos graxos poli-insaturados (PUFAs) em sua membrana. As ligações duplas entre carbonos desses PUFAs confere a membrana plasmática uma maior fluidez, necessária aos processos fisiológicos do espermatozoide como motilidade e fertilização.
