Antioxidant Activities of Ethanolic Extracts Obtained from α-Pinene-Containing Plants and Their Use in Cosmetic Emulsions.

α-Pinene is the bicyclic, unsaturated terpene hydrocarbon present in many plants. Due to its beneficial chemical properties, this compound is of great interest and has found numerous applications as a raw material in many chemical industries as well as in medicine and cosmetics. The aim of this study was to evaluate the antioxidant activities of ethanolic extracts obtained from plants containing α-pinene and to test the properties of cosmetic emulsions prepared with these extracts.

Orchil and Tyrian Purple: Two Centuries of Bedfords from Leeds.

A two-century-old archive relating to a Leeds dye manufacturer emerged a number of years ago from a Devon attic. Most items in the archive date from the mid-nineteenth century to the first quarter of the twentieth, a period of dye history when natural dyes overlapped with and were gradually replaced by synthetics. The archive contains material relevant to three generations of the Bedford family's manufacturing and research successes, as well as its close connections to the family of William Henry Perkin.

6-bromoindigo dye.

6-Bromoindigo (MBI) [systematic name: 6-bromo-2-(3-oxo-2,3-dihydro-1H-indol-2-ylidene)-2,3-dihydro-1H-indol-3-one], C(16)H(9)BrN(2)O(2), crystallizes with one disordered molecule in the asymmetric unit about a pseudo-inversion center, as shown by the Br-atom disorder of 0.682 (3):0.318 (3).

Role of everlasting triplet expansions in protein evolution.

Analysis of occurrence of simple amino acid repeats in large ensemble of prokaryotic and eukaryotic sequences reveals that nearly all amino acids found in the repeats belong to those which have in their codon repertoires aggressively expanding triplets, all of three known pathologically expanding classes GCU (GCU, CUG, UGC, AGC, GCA, CAG), GCC (GCC, CCG, CGC, GGC, GCG, CGG), and AAG (AAG, AGA, GAA, CTT, TTC, TCT). This is observed especially clear in the first exons of proteins of higher eukaryotes. The data are interpreted as manifestation of everlasting triplet expansions, which, presumably, started from the very origin of the triplet code.

Health status of personnel occupationally exposed to radiowaves.

The findings of medical examinations performed in two groups of persons occupationally exposed to microwaves and radiofrequency radiation are presented in comparison with control findings. A group of 49 radar operators from the Zagreb Air Traffic Control was examined twice within a period of 18 months. The other group comprised 46 workers employed in radio relay stations.
