Cigarette mainstream smoke (MS) contains a number of structurally diverse substituted phenols. Recent quantitative structure activity relationship (QSAR) studies on phenols show that substituted phenols with electron-releasing groups can form potentially toxic phenoxyl-free radicals. In contrast, substituted phenols with electron-withdrawing groups do not form phenoxyl-free radicals but exert t...

Recent studies have shown that blueberries may have cardiovascular and cognitive health benefits. In this work, we investigated the profile of plasma and urine (poly)phenol metabolites after acute and daily consumption of wild blueberries for 30 days in 18 healthy men. The inter-individual variability in plasma and urinary polyphenol levels was also investigated. Blood samples were collected at...

Picea smithiana is one of the plants belongs to family pinaceae that has not been explored scientifically from pharmaceutical point of view. The present study targeted to explore the antioxidant potential of Picea smithiana growing in Bhadewah region (Shoj dhar) at the altitude of 11000 feats of Jammu and Kashmir, India. Three types of extracts were prepared from leaf and Bark part of the plant...

An enzyme-containing microfluidic biochip has been developed for the oxidative polymerization of phenols. The biochip consists of a simple T-junction with two feed reservoirs 20 mm apart and a microreaction channel 30 mm long. The channel is 15 microm deep and 200 microm wide at the center, giving a reaction volume of 90 nL. The biochip was fabricated using conventional photolithographic method...

Laccases are multi-copper oxidases widely distributed in plants, animals, insects and microorganism. These enzymes catalyze the one-electron oxidation of a wide range of organic and inorganic substances, including mono, di and poly phenols, aminophenols, methoxy phenols, aromatic amines and ascobate with the concomitant four electron reduction of oxygen to water. Laccase has the focus of much a...

The objectives of the present study were to evaluate and compare the antimicrobial activities of olive oil and vinegar against Salmonella and Escherichia coli. The spread plate method was used to determine the growth of Salmonella and Escherichia coli. The concentration of preservatives used for inhibition of Salmonella and Escherichia coli was determined by using minimum inhibitory concentrati...

Abstract Exercise-induced muscle damage (EIMD) is associated with oxidative stress and inflammation, soreness, reductions in function. Cocoa flavanols (CF) are (poly)phenols antioxidant anti-inflammatory effects thus may attenuate symptoms of EIMD. The purpose this narrative review was to collate evaluate the current literature investigating effect CF supplementation on markers exercise-induced...
