Application

Benzaldehyde may be used as a reference standard for the determination of benzaldehyde, the toxic oxidation product of benzyl alcohol used as a preservative in injectable formulations of the non-steroidal anti-inflammatory drugs, diclofenac, and piroxicam, and in vitamin B-complex injection solutions by capillary gas chromatography.

Inheritance of acquired characteristics without changes in DNA sequence has been called transgenerational epigenetics. This review looks at studies that used the model system Caenorhabditis elegans to uncover mechanisms of transgenerational epigenetics in studies of RNA interference, studies of longevity...
