Several naturally occurring essential oils including carvacrol, anethole, cinnamaldehyde, cinnamic acid, perillaldehyde, linalool, and p-cymene were evaluated for their effectiveness in reducing decay and increasing antioxidant levels and activities in 'Duke' blueberries ( Vaccinium corymbosum). Carvacrol, anethole, and perillaldehyde showed the capability to promote total anthocyanins and tota...

Rhodococcus sp. strain DK17 was isolated from soil and analyzed for the ability to grow on o-xylene as the sole carbon and energy source. Although DK17 cannot grow on m- and p-xylene, it is capable of growth on benzene, phenol, toluene, ethylbenzene, isopropylbenzene, and other alkylbenzene isomers. One UV-generated mutant strain, DK176, simultaneously lost the ability to grow on o-xylene, ethy...

In this communication, we describe p-xylene oxidation with molecular oxygen at 373 K and atmospheric pressure using N-hydroximide catalysts. p-Xylene conversion was rather high over the first 2 h of reaction and complete by the end of the experiment. The product distribution curves versus reaction time are typical of consecutive reactions. The main intermediate product is p-toluic acid. Peak co...

The removal of xylene vapors was studied in a biofilter packed with a new hybrid (scoria/compost) packing material at various inlet loads (IL) and empty bed residence times (EBRT) of 90, 60, and 40s. The best performance was observed for EBRT of 90s, where a removal efficiency of 98% was obtained under steady state condition for inlet xylene concentration of 1.34 g m(-3), while a maximum elimin...

The joint effect of Antoxid (AX), extract from Radix Scutellariae baicalensis, with vitamin C on ferric reducing human plasma ability (FRAP) was examined. In order to explain the mechanism of Antoxid inhibiting effect on lipid peroxidation stimulated by xylene, its influence on hydroxyl radical generation was examined. The preventing and repairing effect of Antoxid was evaluated towards the lip...

In this study, changes in testicular tissues of rats subjected to xylene and formaldehyde inhalation were evaluated. Three experimental groups were included in the study. Each group of rats was exposed to formaldehyde (6 ppm), technical xylene (300 ppm) or a combination of these two agents (150 ppm+3 ppm) for 8 weeks (8 h/d). Control groups were maintained for a period of eight weeks under the ...

Volatile organic compounds (VOCs) react with atmospheric OH, NO 3 , and O to form having lower volatility, contributing secondary aerosols (SOAs). Consequently, characterizing the reaction intermediate for this is essential modeling formation of SOAs. Herein, we proposed a mechanism ozonolysis p ‐cymene calculated energies intermediates generated during each step by density functional theory (D...

BACKGROUND The increasing prevalence of obesity is considered a serious global health threat. Mainly due to change of diet and reduced physical activity, obesity is an important risk factor for chronic diseases. A higher level of cytokines and a general inflammatory state has also been associated with this condition. With this regard, potential anti-obesity compounds with anti-inflammatory prop...

Eight male subjects were experimentally exposed to toluene, p-xylene, and a combination of toluene and p-xylene in order to study the influence of coexposure and exposure to different levels of each solvent on their uptake and elimination. The exposures were performed for four hours at exposure levels equivalent to or lower than the Swedish threshold limit value for toluene, 300 mg/m3 (3.2 mmol...
