RESEARCH ARTICLE Open Access Acute oral toxicity and antioxidant studies of an amine-based diselenide Mohammad Ibrahim1,2*, Niaz Muhammad1, Musadiq Ibrahim3,4, Muhammad Idrees Khan1, Muhammad Ishaq Ali Shah1, Muhammad Said1, Waliullah Khan1, Jean Paul Kamdem5 and Joao Batista Teixeira Rocha2 AbstractAuthor: Mohammad Ibrahim, Mohammad Ibrahim, Niaz Muhammad, Musadiq Ibrahim, Musadiq Ibrahim, Muhammad Idrees.
Toxicity studies involving chromium have shown that the protective effect of vitamin E against lipid peroxidation may be associated rather with the level of non-enzymatic antioxidants than the activity of enzymatic antioxidants. The risk of macular degeneration can be reduced through the consumption of antioxidant-rich foods, supplements, and nutraceutical formulas. This review focuses on the antioxidants, vitamins, and minerals that have been reported for reducing the risk of macular degeneration and other eye-related diseases. Antioxidants including anthocyanins, carotenoids, flavonoids, and Cited by: 2.
reproductive toxicity studies ensure information about the effects on gonadal function, estrous cycles, conception, parturition, lactation (Joint FAO/WHO Expert Committee, ). Reproductive studies constitutively target multigenerational studies as a result of human exposure to most food additives and preservatives during the whole lifetime. Antioxidants, an international, peer-reviewed Open Access journal. Dear Colleagues, Reactive oxygen species (ROS) are naturally produced during several cellular pathways of aerobic metabolism, including oxidative phosphorylation, electron transport chains in mitochondria, the activity of oxido-reductase enzymes, and immunological reactions, such as phagocytosis.

Many studies which involved both in vivo and in vitro experiments have reported that the Orthosiphon stamineus leaves possess a wide range of pharmacological properties such as, anti-inflammatory, analgesic, gastroprotective, antipyretic, and hepatoprotective effects.
The present study was conducted to determine the antioxidant potential, which is responsible for the wide Cited by: 9. Quantitative toxic and antioxidant characteristics of the fullerenols (effective concentrations, concentration ranges, D G T, and D OxT) were found to depend on the number of oxygen substituents.
Lower toxicity and higher antioxidant activity were determined in solutions of fullerenols with fewer oxygen substituents (x+y = 24–28).Cited by: 1. PURPOSE The benefits and risks of supplementation with antioxidants during cancer therapy have been a controversial area.
Few studies have systematically evaluated dietary intake of antioxidants with toxicity and survival in childhood cancer. We sought to determine the role of dietary intake of antioxidants on rates of infections, mucositis, relapse, and disease-free.
Nutraceuticals and food supplements frequently contain huge dosages of antioxidants. It is not generally recognised that high intake of antioxidants may also have adverse effects.
Three antioxidants i.e. vitamin E, β-carotene and lipoic acid are used to illustrate general considerations on the toxicity of by: Oxidative stress (OxS) constitutes a disturbance caused by an imbalance between the generation of free radicals and antioxidant system, which causes damage to biomolecules.
This, in turn, may lead the body to the occurrence of many chronic degenerative diseases. Therefore, it is very important to know the functioning of those endogenous (and Anti-Oxidants and Toxicity Studies book antioxidants Cited by: 2.
Maca plant belongs to Brassicaceae such as broccoli, cabbage and radish, and has a tuberous root. With the declaration of The Food and Agriculture Organization (FAO) that maca is a forgotten and disappearing plant, the fresh, dried, powder and organic forms of it take part in nutrition as a food supplement world-wide.
Studies have focused on antioxidant effects Cited by: 1. At this point, it is interesting to discuss toxicity data. In this sense, we argue that dosage must be considered and that not all antioxidants are innocuous, but food additives at the doses used can be considered safe.
Surely, this data-based opinion can Cited by: 1. Generally, higher antioxidant activity was noted for tea powder and tea bags than tea leaves. Antioxidant activity was positively influenced by increased extraction time and temperature.
However, other studies showed that the extraction efficacy of phenolic compounds from white. The interplay between free radicals, antioxidants, and co-factors is important in maintaining health, aging and age-related diseases.
Free radicals induce oxidative stress, which is balanced by the body’s endogenous antioxidant systems with an input from co-factors, and by the ingestion of exogenous antioxidants. Studies have shown that the most efficient compounds in inhibiting lipid oxidation in emulsions and other food products during storage are not always directly comparable with antioxidant efficacies measured in antioxidant assays (Alamed, Chaiyasit, McClements, & Decker, ; Sørensen et al., ).
The anthracycline antibiotic adriamycin (doxorubicin) is one of the most effective chemotherapeutic agents against a wide variety of cancers.
However, its use is seriously limited by the development in the heart of acute and chronic toxic by: However, Cu toxicity resulting from exposure to excess Cu caused by accident, occupational hazard, environmental contamination, or inborn errors of Cu metabolism does occur.
This article emphasizes the cellular effects of excess Cu, as well as the role of oxidative stress and antioxidant nutrients in Cu by: The recognition that antioxidants could, vice versa, interact with the signalling pathways underlying the responses to acute (and repeated) bouts of exercise has contributed important novel aspects to the continued discussion on antioxidant requirements for by: 1.
Antioxidants, such as vitamins C and E and carotenoids, may help protect cells from damage caused by free radicals. Other naturally occurring antioxidants include flavonoids, tannins, phenols and lignans.
Plant-based foods are the best sources. These include fruits, vegetables, whole grains, nuts, seeds, herbs and spices, and even cocoa. Antioxidants are man-made or natural substances that may prevent or delay some types of cell damage.
Diets high in vegetables and fruits, which are good sources of antioxidants, have been found to be healthy; however, research has not shown antioxidant supplements to be beneficial in preventing diseases.

Antioxidants decrease the damage done to cells by reducing oxidants before they can damage the cell. Virtually all studies of mammals have concluded that a restricted calorie diet extends the life span of mammals by as much as %. This remarkable finding suggests that food is actually more damaging than smoking.
This new book brings. antioxidant, substance that prevents or slows the breakdown of another substance by oxygen. Synthetic and natural antioxidants are used to slow the deterioration of gasoline and rubber, and such antioxidants as vitamin C (ascorbic acid), butylated hydroxytoluene (BHT), and butylated hydroxyanisole (BHA) are added to foods (see food additives) to prevent them from becoming.
Antioxidants and its functions in human body - A Review Although initial studies suggested that antioxidant supplements might promote health, later large clinical trials of antioxidant.

Toxicity and apoptosis induced by cationic liposomes as well as their mechanisms have been found to be definitely associated with ROS generation.
Thus, the antioxidant effect of Asparagus racemosus root extract may be applicable for protecting cells from apoptosis related to ROS generation. Such an application would provide an alternative for. Abstract. Fullerenes are a relatively new group of compounds and represent a class of sphere-shaped molecules made exclusively of carbon atoms.
Since their discovery inmany aspects of both fullerene and its analogues have been intensively studied to reveal their physical and chemical reactivity, as well as potential use in biological by: Understanding antioxidants Some vitamins and minerals — including vitamins C and E and the minerals copper, zinc, and selenium — serve as antioxidants, in addition to other vital roles.
"Antioxidant" is a general term for any compound that can counteract unstable molecules called free radicals that damage DNA, cell membranes, and other.
