BACKGROUND (2S)-Pinocembrin is a chiral flavanone with versatile pharmacological and biological activities. Its health-promoting effects have spurred on research effects on the microbial production of (2S)-pinocembrin. However, an often-overlooked salient feature in the analysis of microbial (2S)-pinocembrin is its chirality. RESULTS Here, we presented a full characterization of absolute conf...

In many publications the term “elaioplasts” denotes, in accordance with the meaning, plastids containing lipids [1,2]. However, in the past this name was used according to Wakker [3] who was the first to apply it with reference to lipidic structures, often as big as a cell nucleus, which he identified in five Vanilla species. Similar structures were later described in more than 120 species belo...

For 2010, we now begin the 10th year of the 21st century and eCAM has occupied five of them. eCAM covers have presented art to focus on some of the cultures, where integrative medicine was born and still thrives side by side with western medicine. These have been represented by art from Japan, Korea, India, Italy, China. Other vibrant cultures where CAM flourishes were not intentionally omitted...

Meiosis I in males of the Dipteran $ciara coprophila results in the nonrandom distribution of maternally and paternally derived chromosome sets to the two division products. Based on an earlier study (Kubai, D. E 1982. J. Cell Biol. 93:655-669), I suggested that the meiosis I spindle does not play a direct role in the nonrandom sorting of chromosomes but that, instead, haploid sets are already ...

Potyviruses (genus Potyvirus, family Potyviridae) are transmitted by aphids in a non-persistent manner and cause significant losses in many crops including bulbous ornamentals. Host range, symptoms, physical and biochemical properties of many potyviruses in bulbous ornamentals are reported, but, especially for viruses infecting ornamentals of minor economical importance, sequence data are still...
