The effects of lipoic acid (LA) on the antioxidant status of broilers were investigated. Birds (1 day old) were randomly assigned to four groups and fed corn-soybean diets supplemented with 0, 100, 200, 300 mg/kg LA, respectively. The feeding program included a starter diet from 1 to 21 days of age and a grower diet from 22 to 42 days of age. Serum, liver and muscle samples were collected at 42...

Nostoc sphaeroides Kuetzing has been used as a traditional medicine in China to treat a variety of ailments. This research identified the antioxidant activities of polysaccharide extract from Nostoc sphaeroides. The extract, which contains 46.2% carbohydrates, exhibited an effective scavenging capability on superoxide radical, hydroxyl radicals in non site-specific as well as site-specific assa...

In the past few years many initial and subsequent clinical studies have demonstrated that hydrogen can act as an important physiological regulatory factor to cells and organs on the antioxidant, anti-inflammatory, anti-apoptotic and other protective effects. So far several delivery methods applied in these studies have proved to be available and convenient, including inhalation, drinking hydrog...

Crude extracts of Sedum formosanum N.E.Br. obtained from n-butanol partition (BP) and isopropanol salting-out pretreatment (ISP) were analyzed using antioxidation assays. The results indicated that the extract from ISP contained more potent antioxidants and thus exhibited more antioxidant activity in all the assays. The superoxide radical-scavenging activity and inhibition of nitric oxide radic...

Enzymatic proteolysis is helpful to release bioactive peptides encrypted in food proteins. The antioxidant capability of soy protein isolate (SPI) hydrolyzed with a novel protease preparation from Chryseobacterium sp. kr6 was investigated. The antioxidant capacity of the hydrolysates was evaluated using radical-scavenging and metal-chelating assays. Maximum values for scavenging of 2,2’-azino-b...

| The carvacrol compound is an antioxidant nutrient, used to enhance growth and productive performance via modification and activation of gastrointestinal tract structure and function and to inhibit/prevent cancer initiations. Numerous studies performed on animal diets supplemented with phytogenic supplements/feed additives containing natural antioxidants such as carvacrol demonstrated its capa...

Rubus coreanus fruits have been employed as a traditional medicine for centuries in the Asia-Pacific region. Its pharmacological action differs according to the different extraction methods utilized and the degree of fruit ripening. In this study, we determined the cellular effect of different ethanol extracts of mature and immature Rubus coreanus fruits in human hepatic cell line, HepG2 cells....

The present investigation was carried out to appraise the levels of total phenols and vitamin C as well as antioxidant potential at three different ripening stages (un-ripe, semi-ripe and fully-ripe) of guava (Psidium guajava L.) fruit collected from three different geographical regions of Pakistan (Islamabad, Faisalabad and Bhakkar). The antioxidant potential of guava fruit extracts was assess...

The barnacle Balanus amphitrite Darwin is a dominant intertidal and major fouling organism. As its life cycle includes both sessile and pelagic phases, adaptation is a necessity to tolerate harsh conditions that are faced in the intertidal and pelagic environment. A downward trend in dissolved oxygen levels in coastal areas has been recently observed, which would have a more prominent effect on...

Received: Revised: Accepted: Published online: March 26, 2015 July 23, 2015 August 25, 2015 December 31, 2015 Tibial Dyschondroplasia (TD) is an important leg problem in fast growing birds that disturbs the proximal tibial growth plate. A study was conducted to evaluate the effects of gambogic acid (GA) on hsp-90 expressions and antioxidant capability in thiram-induced TD chicken. One hundred a...
