INTRODUCTION AND RATIONALE The detection of bioavailable phenol is a very important issue in environmental and human hazard assessment. Despite modest developments recently, there is a stern need for development of novel biosensors with high sensitivity for priority phenol pollutants. DmpR (Dimethyl phenol regulatory protein), an NtrC-like regulatory protein for the phenol degradation of Pseudo...

Bioremediation of phenol was done using Candida tropicalis SSK01 immobilized cells isolated from petroleum contaminated soil. Optimization of phenol degradation studies was carried at 30 °C to 40 °C, pH 6 to 8 and initial concentration of 300 mgl⁻¹ to 900 mgl⁻¹. Candida tropicalis SSK01 cells immobilized using sodium alginate were used in phenol degradation studies. Optimization of phenol degra...

Pilonidal sinus disease is a common medical condition that accounts for almost 15% of anal suppurations with high morbidity. Its management is subject to many variations. In this study, a 25-year experience from 1984 to 2009 of treating pilonidal sinus disease is being reported. A total of 252 patients were included in the study. They were treated by phenol injection, excision and primary closu...

The Amaryllidaceae alkaloids are a family of amino acid derived alkaloids with many biological activities; examples include haemanthamine, haemanthidine, galanthamine, lycorine, and maritidine. Central to the biosynthesis of the majority of these alkaloids is a C-C phenol-coupling reaction that can have para-para', para-ortho', or ortho-para' regiospecificity. Through comparative transcriptomic...

Iron-containing materials have been prepared following several strategies of synthesis and using different silica supports (amorphous, zeolitic and mesostructured materials). Activity and stability of these materials was evaluated on the wet peroxide oxidation of phenol under mild reaction conditions (100 degrees C, air pressure of 1MPa and stoichiometric amount of hydrogen peroxide for the com...

The present investigation was conducted to determine the effect of PBZ and ABA on total phenol contents in different parts of Ocimum sanctum. Paclobutrazol (PBZ) a triazole fungicide, having plant growth regulator (PGR) properties, is reported to inhibit gibberellic acid biosynthesis and increase in abscisic acid and cytokinin contents. So, it necessitates the need to investigate the efficacy o...

Phenol is naturally found in some foods and animal wastes. It is also used as a disinfectant, insecticide and in some pharmaceutical products. Immunotoxicity is considered to be one of the harmful health effects of phenol. Propolis is a mixture of beeswax and resins; it has an antimicrobial, anti-inflammatory, antioxidant and immunomodulatory effect. This study investigates effect of propolis o...

Recently, the formation of reactive oxygen species (ROS) and reactive nitrogen species (RNS) have been implicated in the oxidative deterioration of food products as well as in the pathogenesis of several human diseases such atherosclerosis, diabetes mellitus, chronic inflammation, neurodegenerative disorders and certain types of cancer. Plant secondary metabolites mainly phenolics and flavonoid...

Due to their excellent properties, clays have been widely used in several applications, particularly in catalysis. In this paper, three clays were used as heterogeneous photo-Fenton catalysts for phenol and tyrosol oxidations. Particular attention was given to the effect of the main operating conditions on the process performance. A total conversion was obtained for both organic pollutants with...

the present study was done to investigate the correlation between biochemical changes of grafted tree fruits and rootstock fruits in gorgan university of agricultural science and natural resources in 2012-2013. for this purpose, the antioxidant activity and the total content of phenol and  flavonoid on four rootstocks such as yuzu (citrus junos), shelmahalleh (citrus sinensis var. shel mahalleh...
