According to the Oxford English Dictionary, the suffix ‘omics’ refers to ‘the totality of some sort’. In biology, ‘omics’ techniques are used for the high-throughput analysis of DNA sequences and epigenetic modifications (genomics), mRNA and miRNA transcripts (transcriptomics), expressed proteins (proteomics), as well as synthesised metabolites (metabolomics) in a biological system ...
Volatile organic compounds (VOCs) are organic compounds that have a high vapor pressure at room temperature. [1] They are common and exist in a variety of settings and products, not limited to house mold , upholstered furniture , arts and crafts supplies, dry cleaned clothing, and cleaning supplies . [ 2 ]
Toluene is an organic compound which is mostly harmless to adults and is sometimes abused as an inhalant. Fetal toluene syndrome has been defined and resembles fetal alcohol syndrome with resultant birth defects, but the U.S. Centers for Disease Control and Prevention have identified differentiating features between the two syndromes including FTS having the additional facial features of ...
All volatile metabolites detectable by the human nose are termed an 'odour profile'. The association of altered odour profiles with disease states has long been documented in both eastern and western medicine, and recent advances in robotic sample introduction have increased interest in the volatilome as a source for biomarkers that can be used for non-invasive screening for disease.
Volatile organic compounds (VOCs) are released from many household cleaning products such as disinfectants, polishes, floor waxes, air-freshening sprays, all-purpose cleaning sprays, and glass cleaner. These products have been shown to emit irritating vapors.
Fugitive emissions present other risks and hazards. Emissions of volatile organic compounds such as benzene from oil refineries and chemical plants pose a long term health risk to workers and local communities. In situations where large amounts of flammable liquids and gases are contained under pressure, leaks also increase the risk of fire and ...
Phytoncides are antimicrobial allelochemic [dubious – discuss] volatile organic compounds derived from plants.The word, which means "exterminated by the plant" [citation needed] (from the Greek φυτόν "plant" and the Latin caedere "to kill"), was coined in 1928 by Boris P. Tokin, a Soviet biochemist then studying at Moscow State University. [1]
Volatile blends are proposed to convey a variety of information to insects and plants. "Each plant species and even each plant genotype releases its own specific blend, and the quantities and ratios in which they are released also vary with the arthropod that is feeding on a plant and may even provide information on the time of day that feeding ...
