The detrimental effect of neuronal cell death due to oxidative stress and mitochondrial dysfunction has been implicated in age-related cognitive decline and neurodegenerative disorders such as Alzheimer's disease. The Indian herb Bacopa monnieri is a dietary antioxidant, with animal and in vitro studies indicating several modes of action that may protect the brain against oxidative damage. In p...

Sensible physical exercise is shown to prevent certain neurovascular problems. However, in recent times, non-traumatic sudden death in young athletes has been observed and the incidence level is always very disturbing, because of the spontaneous nature of the occurrence. It most commonly occurs fivefold more in male than female athletes. Although it is believed that congenital cardiovascular di...

air pollution is the most important environmental problem of last century that threatens the health of living organisms, especially plants. so2 is one of the main air pollutants that can cause to imbalance in growth and physiological function of plant in high concentrations. symbiosis of rhizobium bacteria with alfalfa can cause increasing plant growth and plant resistance to abiotic stresses. ...

Coffee is a rich source of dietary antioxidants, and this property, coupled with the fact that coffee is one of the world's most popular beverages, has led to the understanding that coffee is a major contributor to dietary antioxidant intake. Brewed coffee is a complex food matrix with numerous phytochemical components that have antioxidant activity capable of scavenging free radicals, donating...

Effects of Piper guineense (African Black Pepper) Seeds on Lipid Profile, Renal Function Parameters, and Antioxidant Status Cavia porcellus

BACKGROUND Outdoor air pollution, given its demonstrated negative effects on the respiratory system, is a growing public health concern worldwide, particularly in urban cities. Human exposure to pollutants such as ozone, nitrogen oxides, combustion-related particulate matter and oxides of sulfur is responsible for significant cardiopulmonary morbidity and mortality in both adults and children. ...

CONTEXT Previous studies have shown that Spirulina platensis Gomont (Phormidiaceae) (SP) extract has beneficial effects on many disease conditions. The putative protective effects of SP were investigated in diabetic rats. OBJECTIVE The current study investigates the antioxidant effects of SP in diabetic Wistar rats. MATERIALS AND METHODS Alloxan monohydrate (150 mg/kg body weight) was intra...

The objective of this experiment was to investigate the influence of weaning stress and an antioxidant blend on gut health and free radical metabolism in postweaning pigs. A total of 96 pigs from 12 litters were randomly divided by litter to 3 groups with 4 litters each. The control group and the weaning group were fed the basal diet, and the antioxidant group was fed the basal diet supplemente...

The accumulation of reactive oxygen species (ROS) in response to extracellular signals or intracellular biochemical processes can be regulated by the coordinate action of many antioxidant proteins. Because moderate levels of ROS can act as intracellular messengers in many of these processes, this modulation is critical for the transduction of specific signals. The thiol-specific antioxidant (TS...
