Temperature effects explain continental scale distribution of cyanobacterial toxins
2018
Insight into how environmental change determines the production and distribution of cyanobacterial toxins is necessary for risk assessment. Management guidelines currently focus on hepatotoxins (microcystins). Increasing attention is given to other classes, such as neurotoxins (e.g., anatoxin-a) and cytotoxins (e.g., cylindrospermopsin) due to their potency. Most studies examine the relationship between individual toxin variants and environmental factors, such as nutrients, temperature and light. In summer 2015, we collected samples across Europe to investigate the effect of nutrient and temperature gradients on the variability of toxin production at a continental scale. Direct and indirect…
The perception of elite athletes’ guided self-reflection and performance in archery
2016
AbstractSelf-reflection has been shown to enhance professional development in clinical, counselling and educational settings. Recent research found that self-reflection can enhance performance in elite sports. The purpose of this intervention study was two-fold: Firstly, to examine whether a guided reflective diary was effective in enhancing accuracy in elite archery, and secondly, to identify factors facilitating and hindering the usage of the guided reflective diary. Eight Singaporean elite archers (four females, four males), aged 20–24 years, reflected on their training using the diary for a period of five weeks. Their pre- and post-intervention performance scores were collected and qual…
Development of high-performance thin layer chromatography method for identification of phenolic compounds and quantification of rosmarinic acid conte…
2020
ABSTRACT Aim: Representatives of Nepetoideae Burnett subfamily are promising species of the Lamiaceae Martinov family because of accumulating such valuable groups of secondary metabolites as terpenoids and polyphenols. A high-performance thin layer chromatography (HPTLC) fingerprint method for the qualitative determination of phenolic compounds and for the quantification of rosmarinic acid (RA) content in methanol extracts of five species of this subfamily was developed for the first time. Materials and Methods: Dried aerial parts of Dracocephalum moldavica L., Ocimum americanum L., Lophanthus anisatus (Nutt.) Benth., Monarda fistulosa L., and Satureja hortensis L. collected in flowering pe…
