The self-prepared pectin hydroxamic acid has been reported to have antioxidant activities [Yang, S. S., Cheng, K. D., Lin, Y. S., Liu, Y. W., & Hou, W. C. (2004). Pectin hydroxamic acids exhibit antioxidant activities in vitro. Journal of Agricultural and Food Chemistry, 52, 4270-4273]. In this study, the galacturonic acid (GalA), the monomer unit of the pectin polymer, was esterified with acid...

PURPOSE This research paper presents antioxidant and antimicrobial activities of Pedicularis sibthorpii and Pedicularis wilhelmsiana which grow in Azerbaijan/Iran with claimed a lot of therapeutic effects. METHODS DPPH assay and agar well diffusion method were carried out to determine antioxidant and antimicrobial activities respectively. RESULTS Methanolic extract showed better antioxidant...

BACKGROUND Oxidative stress has been implicated in the progression of various diseases, which may result in the depletion of endogenous antioxidants. Exogenous supplementation with antioxidants could result in increased protection against oxidative stress. As concerns have been raised regarding synthetic antioxidant usage, the identification of alternative treatments is justified. The aim of th...

Boswellia serrataBoswellia serrata has a prominent role in TBI outcome’s and perhaps protect neurons through modulating inflammatory and antioxidant pathways

Bcl2's antiapoptotic function is regulated by phosphorylation. Bcl2 also regulates cell cycle progression, but the molecular mechanism is unclear. Bcl2 is functionally expressed in mitochondria where it can act as an antioxidant that may regulate intracellular reactive oxygen species (ROS). Since ROS have been reported to act as second messengers in cell signaling, we tested whether Bcl2 phosph...

BACKGROUND Thoracic Endovascular Aortic Repair (TEVAR) has substantially decreased the mortality and major complications from aortic surgery. However, neurological complications such as spinal cord ischemia may still occur after TEVAR. S-100β is a biomarker of central nervous system injury, and oxidant injury plays an important role in neurological injury. In this pilot study, we examined the t...

The pepino (Solanum muricatum) is an edible and juicy fruit native to the Andean region which is becoming increasingly important. However, little information is available on its phenolic composition and bioactive properties. Four pepino varieties (37-A, El Camino, Puzol, and Valencia) and one accession (E-7) of its close wild relative S. caripense were characterized by HPLC-DAD-MS(n)/ESI. Twent...

Reactive oxygen species (ROS) are elevated in humans with hypertension many of which develop end-stage renal disease (ESRD), and antioxidant capacity is decreased. About one-half of essential hypertensives have a salt-sensitive type of hypertension, and the amount of renal damage that occurs in salt-sensitive hypertensives greatly exceeds that of non-salt-sensitive hypertensives. Antioxidant th...

objectives: the objective of this study was to analyze the fatty acid content, antioxidant, and antibacterial activities of hydro-methanolic extract of adonis wolgensis l. (a. wolgensis l.) growing wild in north of iran. materials and methods: oils of a. wolgensis l. was obtained by means of soxhlet apparatus from leaves and stems. methyl esters were derived from the oily mixtures by trans-este...
