a:4:{s:10:"Background";s:513:"Therapeutic potential of in vitro maturation (IVM) in infertility is growing with great promise. Although significant progress is obtained in recent years, existing IVM protocols are far from favorable results. The first aim of this study was to investigate whether two step IVM manner change reactive oxygen species (ROS) and total antioxidant capacity (TAC) levels....

Trifolium alexandrinum is traditionally used in various human ailments, including renal dysfunctions. The present experiment was designed to investigate antioxidant and nephroprotective effect of T. alexandrinum methanolic extract (TAME) against CCl4-induced oxidative stress in albino rats. Results of in vitro study revealed significant (P < 0.05) antioxidant effects. The ameliorative role of T...

BACKGROUND Oxidative stress in an intracellular environment created by the accumulation of reactive oxygen species results in oxidative damage to biomolecules which ultimately become a hallmark for severe diseases like cancer, aging, diabetes, and cardiovascular and neurodegenerative diseases. METHODS Various in vitro assays were employed to assess the antioxidant potential of strain, DNA pro...

The purpose of this study was to screen the antioxidant activity of medicinal plant extracts from the Brazilian cerrado, through other methods than the total phenolic content and its correlation with the antioxidant activity. Ethanolic extracts of ten species were evaluated through three antioxidant assays, in vitro, including 2,2-diphenyl-1-picrylhydrazyl (DPPH), total antioxidant activity and...

Many essential oils (EOs) of different plant species possess interesting antimicrobial effects on buccal bacteria and antioxidant properties. Eugenia klotzschiana Berg (pêra-do-cerrado, in Portuguese) is a species of Myrtaceae with restricted distribution in the Cerrado. The essential oils were extracted through the hydrodistillation technique using a modified Clevenger apparatus (2 hours) and ...

The objective of this study was to investigate characteristics and functionality of yogurt applied red ginseng extract. Yogurts added with red ginseng extract (0.5, 1, 1.5, and 2%) were produced using Lactobacillus acidophilus and Streptococcus thermophilus and stored at refrigerated temperature. During fermentation, pH was decreased whereas titratable aicidity and viable cell counts of L. acid...

BACKGROUND Flavonoids and other polyphenols play a protective role in liver diseases and possess a high antioxidant capacity. OBJECTIVE To compare and evaluate the antioxidant and hepatotoprotective activities of 4 deserts plants, Fagonia indica Burm. f., Calotropis procera R.Br., Zygophylum hamiense Schweinf. and Salsola imbricata Forssk. in correlation to their composition especially their ...

Red cactus pear has significant antioxidant activity and potential as a colorant in food, due to the presence of betalains. However, the betalains are highly thermolabile, and their application in thermal process, as extrusion cooking, should be evaluated. The aim of this study was to evaluate the effect of extrusion conditions on the chemical components of red cactus pear encapsulated powder. ...

Spondias purpurea is used in folk medicine to treat diarrhea and diuresis. The objective of this study was to evaluate the phytochemical profile and antioxidant and antiulcer activities of the hexane extract of the leaves of S. purpurea (SpHE). Phytochemical profile was evaluated via thin layer chromatography (TLC) and HPLC. SpHE was screened for antioxidant activities using DPPH, ABTS, FRAP, a...

Effect of cigarette smoke on lipid peroxidation (LPX) and antioxidant enzymes like catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and glutathione-S-transferase (GST) in various organs like brain, heart, lung, liver and kidney of the albino rats exposed to cigarette smoke for 30 min/day for a period of 30 days were assayed. It was observed that the lipid peroxide lev...
