“…Steroids are organic compounds with three hexagonal and one pentagonal carbon rings arranged in specific configuration with several functional groups found in plants, animals and fungi (Streck, 2009). Ergosterol is a precussor of vitamin D found in mushrooms membrane and known to vary among species depending on the physiological state of the mushroom (Chiocchio & Matković, 2011).…”

Background: In the recent years natural resources are being in focus due to their great potential to be exploited in the discovery/development of novel bioactive compounds and, among them, mushrooms can be highlighted as alternative sources of anti-inflammatory agents. Scope and approach:The present review reports the anti-inflammatory activity of mushroom extracts and of their bioactive metabolites involved in this bioactive action.Additionally the most common assays used to evaluate mushrooms anti-inflammatory activity were also reviewed, including in vitro studies in cell lines, as well as in animal models in vivo. Key findings and conclusions:The anti-inflammatory compounds identified in mushrooms include polysaccharides, terpenes, phenolic acids, steroids, fatty acids and other metabolites.Among them, polysaccharides, terpenoids and phenolic compounds seem to be the most important contributors to the anti-inflammatory activity of mushrooms as demonstrated by numerous studies. However, clinical trials need to be conducted in order to confirm the effectiveness of some of these mushroom compounds namely, inhibitors of NF-κB pathway and of cyclooxygenase related with the expression of many inflammatory mediators.

To ensure food supply, phosphorus must be recycled, for which an appealing method is using struvite fertilizer from human excreta. One struvite from black water and another from urine were assessed for safety under Dutch regulations, and for effectiveness as P fertilizer in a maize field experiment and a literature review. Both struvites contained 12% P, 12% Mg, 6% N, and 0.5-1.5% of several micronutrients. Struvites did not exceed Dutch regulations for heavy metals or pathogens, and based on literature, organic toxins should be far below regulatory limits. In this study and 18 others, struvite appears to have similar effectiveness to soluble fertilizer. Early in the season, 200 kg P 2 O 5 ha -1 of black water struvite and soluble phosphorus improved maize performance (P<0.05), however at harvest, differences in yield and biomass P content were not significant. Problems of Mg accumulation in soil can be avoided by liming and accurate fertilization. Overall, the studied struvites are safe and effective fertilizers.

“…Various chemical and biological tools have been developed and used in the screening of estrogenic compounds in the environment, and the combinations of both tools could provide complementary information for contamination assessment Fu et al, 2007;Labadie and Hill, 2007;Bicchi et al, 2009;Streck, 2009;Zhao et al, 2009). Chemical analysis using gas chromatographyemass spectrometry (GCeMS) or liquid chromatographyetandem mass spectrometry (LCeMS/MS) was applied to determine target estrogenic compounds in rivers at ng/L to mg/L levels (Kolpin et al, 2002;Kim et al, 2007;Ko et al, 2007;Labadie and Hill, 2007;Mici c and Hofmann, 2009;Ying et al, 2009).…”

“…E-SCREEN, yeast estrogen screen (YES) and estrogen responsive chemically activated luciferase (ER-CALUX)) based on the interaction between chemicals and estrogenic receptors can be used to evaluate the integrated estrogenic activity of environmental samples, without the necessity of knowing all compounds present that contribute to the activity (Soto et al, 1995;Routledge and Sumpter, 1996;Legler et al, 2002). Combined in vitro bioassay and chemical analysis could be used to better assess causal links between effects observed in the aquatic environment and chemical analysis results (Sumpter and Johnson, 2008;Viganò et al, 2008;Streck, 2009). However, more research is needed for the assessment of estrogenicity in aquatic environments by using the combined chemical and biological tools.…”
