This exploratory study was designed to assess the effectiveness of a lignan-rich extract of flaxseed hulls (LinumLife EXTRA®) in alleviating symptoms in subjects with benign prostatic hyperplasia (BPH) compared with placebo. Two dosages of extract were compared against placebo in a double-blinded, randomized, parallel, multicenter study. Newly diagnosed cases of BPH in patients aged 45-75 years with an American Urological Association Symptom Index (AUASI) score of ≥13 were included. Study treatment consisted of 500 or 1000 mg of extract containing 100 mg (low-dose active [LDA] group, n=26) or 200 mg (high-dose active [HDA] group, n=26) of secoisolariciresinol diglucoside (SDG), respectively. The placebo (P) group (n=28) received matching maltodextrin capsules. Sixty subjects (LDA [n=19], HDA [n=20], and P [n=21]) completed the study as per the protocol requirements. Change in the AUASI score within a period of 8 weeks, from baseline to end of treatment, was assessed. Significant improvement of obstructive symptoms and management of irritable BPH symptoms was achieved in all groups after treatment. Due to a strong placebo effect, there was no statistical difference between the groups that were treated with flaxseed hull extract as compared with the placebo group. Treatment with flaxseed hull extract did not lead to adverse effects compared with placebo. Supplementation with flaxseed hull extract was found to be safe and well-tolerated and may have improved the quality of life of individuals with BPH. The significant placebo effect as well as the number of subjects per treatment group and the relative short duration of the study may explain the lack of statistical significance between groups. © Copyright 2015, Mary Ann Liebert, Inc. and Korean Society of Food Science and Nutrition Source

Mycotoxin Research | Year: 2010

On the basis of the outcome of an European proficiency test series conducted on behalf of the CAOBISCO (Association of the Chocolate, Biscuit and Confectionery Industries of the EU) expert group on ochratoxin A, a new harmonised method was developed for the analysis of ochratoxin A in liquorice extracts. This method works without the use of halogenated solvents because, as the proficiency test showed, an aqueous extraction solution can be used instead of, for example, chloroform, whose use is restricted in the EU. The main objective of this method validation study was to check the performance of this harmonised method. To carry out the method validation study, a set of three different test samples (one liquorice powder and two liquorice pastes) and a liquorice powder sample with an indicated range of ochratoxin A (a so-called sunshine sample) was distributed to 21 laboratories in ten countries throughout Europe and to one laboratory in the USA. The study was evaluated according to internationally recognised guidelines. In terms of its repeatability and reproducibility for determining ochratoxin A in liquorice extracts with a relative standard deviation for repeatability (RSDr) of between 6.68 and 19.95 and a relative standard deviation for reproducibility (RSDR) of between 17.39 and 29.08 the performance of the harmonised method was found to be in the accepted range of the EU directive for the analysis of mycotoxins in several foodstuffs. © Society for Mycotoxin Research and Springer 2010.

Mycotoxin Research | Year: 2010

A European proficiency test series was accomplished on behalf of the CAOBISCO (Association of the Chocolate, Biscuit and Confectionery Industries of the EU) expert group on ochratoxin A to assess the performance of laboratories in measuring ochratoxin A in samples of various liquorice products. In addition, the impact of the extraction type (mainly with or without the use of halogenated solvents) was to be evaluated. Four different test samples (two liquorice powders and two liquorice pastes) were tested for sufficient homogeneity and distributed to 15 laboratories in 8 countries in Europe. The results were analysed using standard proficiency testing statistical procedures and laboratories were awarded z-scores on the basis of their reported results. The overall evaluation of the results shows a distinct variation between the participating laboratories. Based on a target standard deviation (σ-value) taken from the Horwitz equation, of the 14 laboratories that reported results, satisfactory results (z-score: |Z|≤2.0) were obtained by 60% and 27% of the laboratories, respectively, for the two liquorice powders and by 93% and 53% of the laboratories, respectively, for the two liquorice pastes. Approximately equal numbers of laboratories used extraction types with and without the use of halogenated solvents. ANOVA testing of the results indicates there was no evident trend using different extraction solvents. © Society for Mycotoxin Research and Springer 2010. Source
