The present study was designated to evaluate the antimicrobial and antioxidant activities of the essential oil, obtained by using a Clevenger distillation apparatus, water soluble (polar) and water insoluble (nonpolar) subfractions of the methanol extracts from aerial parts of Satureja hortensis L. plants, and methanol extract from calli established from the seeds using Gamborg's B5 basal media...

The present study provides an update on the betaxanthin (bx) compositions of red and yellow beetroots, yellow-coloured Swiss chard petioles, and yellow-orange cactus pear. Applying RP-HPLC coupled with positive ion electrospray mass spectrometry and by comparison with UV-vis and mass spectrometric characteristics as well as retention times of semi-synthesized reference compounds, 24 betaxanthin...

Previous work has shown that the peptide-like growth factor strepogenin probably occurs in certain proteins such as insulin and trypsinogen at the amino end of the protein (l), and that it is liberated by suitable enzymic digestion. This conclusion suggested a means for attacking the almost insurmountable task involved in separating the one compound strepogenin from the mixture of numerous pept...

A glutamide gelator, 1, was synthesized, and a weak emission enhancement was observed during its gelation. In addition, 1 could be an excellent scaffold for successfully embedding an energy acceptor, 2, into its aggregate to obtain highly efficient energy transfer. An amplification of the emission enhancement was observed in the two-component gels compared to that of the neat gel of 1 during ge...

BACKGROUND Hair is susceptible to exogenous sources of discoloration. There are several exogenous etiologies for yellow hair discoloration, including tobacco. PURPOSE We describe the clinical features of five men with tobacco-associated yellow discoloration of their mustache, a condition known as "smoker's mustache." We also review the characteristics of men with tobacco-associated yellow dis...

THE photosensitive substancecontained -in the -rods of the eyes of ve#tebrates, visual purple, is a chromoprotein, i.e. a protein to which one or more chromophores are attached. Aqueous solutions of visual puirple are-decomposed by light to give an unstable compound "transient orange", which in turn bleaches thermally to "indicator yellow" [Lythgoe, 1937]. Indicator yellow may also be formed wi...

Although a highly effective vaccine is available, the number of yellow fever cases has increased over the past two decades, which highlights the pressing need for antiviral therapeutics. In a high throughput screening campaign, we identified an acetic acid benzodiazepine (BDAA) compound, which potently inhibits yellow fever virus (YFV). Interestingly, while treatment of YFV infected cultures wi...
