BACKGROUND AND AIMS Cultivated flax (Linum usitatissimum) is known to have undergone a whole-genome duplication around 5-9 million years ago. The aim of this study was to investigate whether other whole-genome duplication events have occurred in the evolutionary history of cultivated flax. Knowledge of such whole-genome duplications will be important in understanding the biology and genomics of...

BACKGROUND In chemical pleurodesis for managing pulmonary air leak, tetracycline derivatives are commonly used, and their effectiveness has been established in many studies. Recently, a Viscum album extract was used in chemical pleurodesis. We compared the effects of V. album with those of a tetracycline derivative (doxycycline) to demonstrate the therapeutic effectiveness of the V. album extra...

The influence of Heterodera glycines (soybean cyst nematode) on the interspecific and intraspecific competition associated with Glycine max (soybean) and Chenopodium album (common lambsquarters) was studied in 1988 and 1989 in three de Wit replacement series experiments in growth chambers and microplots. Glycine max was grown alone (1 plant/experimental unit), in intraspecific competition (2 pl...

Flax (Linum usitatissimum L.) is being evaluated as a crop platform for the production of bio-industrial and nutraceutical products. An important consideration for the release of any novel trait is the potential for gene fl ow to wild or weedy relatives and the impact it may have on their populations. The potential for gene introgression from transgenic fl ax to wild relatives, the occurrence, ...

In 2007 a prominent British alternative-rock band, Radiohead, pre-released its album In Rainbows online, and asked their fans to "pick-their-own-price" (PYOP) for the digital download of it. Radiohead’s unorthodox strategy has been considered as a game-changer for the music industry and a commercial success for the band. In this paper, we study weekly music sales between 2004-2012 in the US to ...

BACKGROUND Independent replications of preclinical investigations of homeopathic potencies are rare. However, they are a necessary tool to determine the relevant factors modulating the effects of homeopathic potencies in preclinical systems. OBJECTIVE The goal of the present study was to reproduce a trial published in 1997. An Italian group of researchers investigated the effect of Arsenicum ...

The natural lignan podophyllotoxin, a dimerized product of two phenylpropanoid moieties which occurs in a few plant species, is a pharmacologically important compound for its anticancer activities. Optimization of the in vitro cultures might lead to a renewable source of lignans for medicinal uses. In order to maximize efficiency of podophyllotoxin accumulation via in vitro cultures, the effect...
