Wild Edibles

Foraging in the British Isles is an increasingly popular activity for both personal consumption and for commercial purposes. While legislation and guidelines exist regulating the sustainable collection of wild edibles, the founding principles of the British foraging movement are not well documented. For this research, 36 of the most active foraging instructors of the Association of Foragers were interviewed to understand their background, species collected, sources of knowledge, and problems faced during collection. Altogether, 102 species of leafy vegetables, fruits, fungi, and seaweeds were mentioned as frequently used, while 34 species of roadkill animals were listed, mostly for personal consumption. Instructors reported learning from wild food guidebooks, other foragers, or personal experience. Frequent contact among foragers has led to the standardisation of knowledge and practices among them forming a “new tradition”, partly based on old British traditions but modified by influences from other countries and cultures, both in terms of choice of species and processing techniques. Contrary to expectations, foragers rarely reported clashes with nature conservation or forestry managers. The authors argue that knowledge and practice developed by the Association of Foragers (AoF) are sustainable and could be integrated into the British food and nature conservation system.

Abstract Background: The ectomycorrhizal fungi display strong fluctuations during the mycological season. However, how abiotic parameters affect the fruiting sequences of ectomycorrhizal fungi and also the direction and extent of this effect are not yet tapped adequately. The present study seeks to assess the microclimate effect on the natural production of boletes. Nine permanent plots of 2500 m2 (50m x 50m) split into 25 subplots of 100 m2 (10m x 10m) were installed in three different vegetation dominated respectively by Isoberlinia doka, Isoberlinia tomentosa and Uapaca togoensis. Microclimatic parameters were recorded each 30 minutes throughout by mean of a Micro Station Data Logger - H21-002 the mycological seasons. Each plot was surveyed twice a week (from May to October) over three years (2015, 2016 and 2017) to record the presence/absence of fruit bodies and fresh biomass of boletes. To evaluate the effect of time and microclimate variables on natural production, we used mixed effects and generalized linear models using R version 3.5.3. Results: In total, during the three years (2015, 2016 and 2017), we recorded 14 species of boletes. Species richness does not change over time (P > 0.05). In addition, fresh biomass varies within years and vegetation (P < 0.05). The combination of year and month of collection has a significant effect on the number of fruit bodies (P < 0.05). Only the soil moisture has a significant positive influence on the species richness of boletes (P > 0.05). Conclusions: When the soil moisture decreases by four units, the number of fruit bodies of ectomycorrhizal fungi is significantly reduced by one unit. Therefore, above 0.25 m3 / m3 and below 0.05 m3 / m3 there is a decrease in the number of fruit bodies.

The microbial transformation of ferulic acid (FA) offers a cleaner, more economical alternative for the natural production of flavorings and fragrances. In the present study, the biotransformation of FA using the filamentous phytopathogenic fungi Colletotrichum acutatum and Lasiodiplodia theobromae was researched. Initially, the toxicity of FA against both fungi was evaluated; the FA displayed a moderate toxicity (total inhibition at concentrations ≥ 2000 mg L-1) and apparently a detoxification mechanism was present. Afterwards, the microorganisms were incubated with the substrate at room conditions using a Czapek-Dox culture medium. The results demonstrated that the FA was mainly converted to 4-vinylguaiacol, reaching the highest abundance within the first 48 hours. To a lesser extent, acetovanillone, ethylguaiacol, and vanillin, among others, were produced. Interestingly, the compounds generated in the biotransformation of FA with C. acutatum and L. theobromae have been used as flavorings. Based on the identified metabolites, a possible metabolic pathway was proposed.

© 2014 Elsevier Ltd. This article extends our understanding of the everyday practices of pharmaceuticalisation through an examination of moral concerns over medication practices in the household. Moral concerns of responsibility and discipline in relation to pharmaceutical consumption have been identified, such as passive or active medication practices, and adherence to orthodox or unorthodox accounts. This paper further delineates dimensions of the moral evaluations of pharmaceuticals. In 2010 and 2011 data were collected from 55 households across New Zealand and data collection techniques, such as photo- and diary-elicitation interviews, allowed the participants to develop and articulate reflective stories of the moral meaning of pharmaceuticals. Four repertoires were identified: a disordering society repertoire where pharmaceuticals evoke a society in an unnatural state; a disordering self repertoire where pharmaceuticals signify a moral failing of the individual; a disordering substances repertoire where pharmaceuticals signify a threat to one's physical or mental equilibrium; a re-ordering substances repertoire where pharmaceuticals signify the restoration of function. The research demonstrated that the dichotomies of orthodox/unorthodox and compliance/resistance do not adequately capture how medications are used and understood in everyday practice. Attitudes change according to why pharmaceuticals are taken and who is taking them, their impacts on social relationships, and different views on the social or natural production of disease, the power of the pharmaceutical industry, and the role of health experts. Pharmaceuticals are tied to our identity, what we want to show of ourselves, and what sort of world we see ourselves living in. The ordering and disordering understandings of pharmaceuticals intersect with forms of pharmaceuticalised governance, where conduct is governed through pharmaceutical routines, and where self-responsibility entails following the prescription of other agents. Pharmaceuticals symbolise forms of governance with different sets of roles and responsibilities.

Measurements have been made, by a radioactivation technique, of the 129I formed in uranium by pile-neutron-induced fission, and in pitchblende by the natural fission of uranium. The amount found in the pile-neutron-irradiated uranium corresponds to a fission yield of 0.90% at mass 129. The natural production of 129I in pitchblende is discussed in the light of the mass-spectrometric measurements of spontaneous fission xenon made by Thode and his collaborators. An upper limit of 1 part in 108 can be set for the occurrence of 129I in natural iodine. The pile neutron capture cross section of 129I has been measured as 35 barns.

Angiogenesis is a critical step in the development of ectopic lesions during endometriosis. Although total vascular endothelial growth factor (VEGF) A is elevated in the peritoneal fluid of women with endometriosis, there are contradictory reports on how levels of total endometrial VEGFA are altered in this disease. Furthermore, limited research is available on different VEGFA isoforms in women with endometriosis. Thus, the aim of the present study was to analyse levels of various VEGFA isoforms in women with and without endometriosis at different stages of the menstrual cycle. Quantitative polymerase chain reaction analysis showed that total VEGFA was highest during menstruation in endometriosis compared with controls (P = 0.0373). VEGF121 and VEGF189 were similarly highest during menstruation in endometriosis compared with controls (P = 0.0165 and 0.0154 respectively). The present study is also the first to identify the natural expression of VEGF111 in human tissue, which is also highest during menstruation in endometriosis (P = 0.0464). This discovery of the natural production of VEGF111 in human endometrium, as well as the upregulation of VEGFA isoforms during menstruation in endometriosis, may shed further light on the development and progression of the disease, and improve our understanding of the regulation of endometrial angiogenesis.

This article reviews the problem of measuring the actual radius of curvature for curved sections of existing forest roads, as forestry enterprises require reliable technical information about the current conditions of operated transport networks. It was identified that at this moment, a selection of methods are used for measuring the radii of horizontal curved sections of roads, which have certain advantages and disadvantages in specific natural production conditions. For calculating the radius of curvature for auto forest road projects it is recommended to apply the method of measured angles by chord angle deviation, which is sufficiently accurate for engineering purposes and does not require usage of special high-precision equipment and tools.
