From the time of antiquity two lines of thinking were always predominant, the materialistic and the spiritualistic viewpoint. The materialistic point of view states the human beings and other living creatures come to life according to a specific pattern and constellation of chemicals and molecules. On the other hand, the nonmaterialistic view point emphasizes that the life factor is something...
Abstract Bananas (Musaceae) are one of the world's most common fruit crops and oldest medicinal plants that used to treat a variety infections. There has been recent interest in elucidating efficiency naturally active ingredients, particularly antimicrobials, this plant. This review begins with short background banana plant its cultivars as well brief description parts. Different experimental t...
Recently, a number of endophytic fungi have been discovered that produce volatile organic compounds (VOCs) whilst growing on agricultural waste substrates, whose chemistry is best defined as hydrocarbon and hydrocarbon-like. These compounds have potential use as both 'green chemicals' and fuels. This report discusses the discovery of the first fungus proposed as a producer of 'Mycodiesel'. Also...
BACKGROUND Laboratory and human studies raise concerns about endocrine disruption and asthma resulting from exposure to chemicals in consumer products. Limited labeling or testing information is available to evaluate products as exposure sources. OBJECTIVES We analytically quantified endocrine disruptors and asthma-related chemicals in a range of cosmetics, personal care products, cleaners, s...
The ability of soil venting to inexpensively remove large amounts of volatile organic compounds (VOCs) from contaminated soils is well established. However, the time required using venting to remediate soils to low contaminant levels often required by state and federal regulators has not been adequately investigated. Most field studies verify the ability of a venting system to circulate air in ...
A simple and economical multi-channel optical sensor using corona discharge radical emission spectroscopy is developed and explored as an optical nose for discrimination analysis of volatile organic compounds, wines, and even isomers.
This study tested the effect of acute exposure to a commercial air freshener, derived from fragrant botanical extracts, at an average concentration of 3.16 mg/m(3) total volatile organic compounds on the lexical decision performance of 28 naive participants. Participants attended two 18-min sessions on separate days and were continuously exposed to the fragrance in either the first (F/NF) or se...

The progress of antimicrobial therapy contributes to the development of strains of fungi resistant to antimicrobial drugs. Since cationic surfactants have been described as good antifungals, we present a SAR study of a novel homologous series of 140 bis-quaternary imidazolium chlorides and analyze them with respect to their biological activity against Candida albicans as one of the major opport...
