The aim of this study was to investigate the effects of selenium (Se) on the growth, accumulation and possible mechanisms of Se transport in certain parts (roots, leaves, stamp and apex) of nettle (Urtica dioica L.) plants. Se was supplemented by one-shot and two repeated doses to the soil (2.0 and 4.0 mg Se per kg of substrate). Selenium content in roots increased linearly with dose and was si...

Antioxidants are used to minimize the oxidative changes in meat and meat products. Oxidative changes may have negative effects on the quality of meat and meat products, causing changes in their sensory and nutritional properties. Although synthetic antioxidants have already been used but in recent years, the demand for natural antioxidants has been increased mainly because of adverse effects of...

Butterflies are believed to use mainly visual cues when searching for food and oviposition sites despite that their olfactory system is morphologically similar to their nocturnal relatives, the moths. The olfactory ability in butterflies has, however, not been thoroughly investigated. Therefore, we performed the first study of odour representation in the primary olfactory centre, the antennal l...

The Internet, the fastest growing technology in society, has been driven by the public's hunger for fast, cheap communication. The modern patient increasingly presents to their doctor with an Internet diagnosis and treatment plan, obtained from a website with inaccurate or highly biased information. Doctors have limited access to the Internet in the workplace and often find it difficult to answ...

BACKGROUND The common stinging nettle, Urtica dioica L. sensu lato, is an invertebrate "superhost", its clonal patches maintaining large populations of insects and molluscs. It is extremely widespread in Europe and highly variable, and two ploidy levels (diploid and tetraploid) are known. However, geographical patterns in cytotype variation require further study. NEW INFORMATION We assembled ...

Resent studies investigating aeroponic cultivation of medicinal plants have provided encouraging results for increasing yields, shortening time to maturity, and improving consistency and overall quality of produce over field production. The goal of the current study was to determine the applicability of aeroponic technology for the cultivation of the traditionally field grown herbaceous medicin...

AIM The objective of this study was to investigate the possible protective role of nettle Urtica dioica (UD) against Hg-induced toxicity. MATERIALS AND METHODS A total of 28 rats were equally divided into four groups: the control, the Hg (0.8 g HgCl2/kg in the diet), the UD (1.5 ml UD/rat by gavage), and the Hg+UD group. HgCl2 was daily dissolved in distilled water and immediately mixed with ...

Recent development of environmental DNA (eDNA) analysis allows us to survey underwater macro-organisms easily and cost effectively; however, there have been no reports on eDNA detection or quantification for jellyfish. Here we present the first report on an eDNA analysis of marine jellyfish using Japanese sea nettle (Chrysaora pacifica) as a model species by combining a tank experiment with spa...

This article notes the growing attractiveness of concepts ‘‘borrowed’’ from chaos theory in organizational studies. Many of these interpretations display sentiments broadly congruent with a ‘‘postmodern’’ approach to organization. Indeed chaos theory itself is presented as part of a similar postmodern shift within natural science. However, these sentiments have been subject to stinging criticis...
