INTRODUCTION: Panaeolina foenisecii is one of the most common and widely distributed lawn mushrooms in Europe and North America, and frequently involved in accidental mushroom ingestion, mainly in children. Nevertheless, there is contradictory information regarding the toxicity profile of P. foenisecii in the literature. Objective of the study was to assess clinical effects with particular attention on psychoactive properties of P. foenisecii in case of accidental oral exposure. METHODS: This observational case series is based on prospectively collected data on mushroom poisoning using a structured data collection form, and it was performed in seven poisons centres in Germany and Switzerland...

Hydrothermal Carbonization (HTC) is a thermochemical process that converts wet organic matter into a sterile, high-calorific solid material called hydrochar. This technology is considered an interesting option for low- and middle-income urban settings, often lacking adequate services and high fraction of wet organic waste. The aim of this study was to study the influence of the loading rate (total solid content) and the maximum temperature reached on the resulting energy ratio (ER) of the process and the fuel properties of the obtained hydrochar...

In the present study, we demonstrate the utility of "admixture screening" for the discovery of new multicomponent heterogeneous Pd catalyst compositions that are highly effective for aerobic oxidative methyl esterification of primary alcohols. The identification of possible catalysts for this reaction was initiated by the screening of simple binary and ternary admixtures of Pd/charcoal in combination with one or two metal and/or metalloid components as the catalyst. This approach permitted rapid evaluation of over 400 admixture combinations for the oxidative methyl esterification of 1-octanol at 60 °C in methanol...

There is an urgent need to discover and progress anti-infectives that shorten the duration of tuberculosis (TB) treatment. Mycobacterium tuberculosis, the etiological agent of TB, is refractory to rapid and lasting chemotherapy due to the presence of bacilli exhibiting phenotypic drug resistance. The charcoal agar resazurin assay (CARA) was developed as a tool to characterize active molecules discovered by high-throughput screening campaigns against replicating and non-replicating M. tuberculosis. Inclusion of activated charcoal in bacteriologic agar medium helps mitigate the impact of compound carry-over, and eliminates the requirement to pre-dilute cells prior to spotting on CARA microplates...

The synthesis of ligand-free sub-nanometric metal clusters on a large scale suffers typically from very low yields (<5% yield) and needs very high dilutions. Here we show that Au clusters can be prepared with ethylene-vinyl alcohol copolymers (EVOH), charcoal, and different metal oxides (CeO2, Al2O3, TiO2 and ZnO) in >15% yields, as unambiguously determined using a very simple and extremely sensitive analytical reaction test.

Sorghum stalks were evaluated to generate clean sugars; enzymatic hydrolysis efficiency of acid pretreated biomass was significantly low (12.3 g sugar/g pretreated biomass) compared to alkali method (49.1 g sugar/g pretreated biomass). Inhibitory compounds derived from acid pretreatment, such as hydroxymethyl furfural (HMF) and furfural, were effectively removed using an appropriate detoxification method using 1% (w/v) activated charcoal. The resin mixture containing cationic exchangers (DOWEX 50WX8) and anionic exchangers (IRA 743) in 7:3 ratio at pH 2...

The present study investigated the response to ozone (O3) of two cultivars (cv.'Romana' and cv. 'Canasta') of irrigated lettuce grown in an open-top chamber (OTC) experiment in Mediterranean conditions. Two different levels of O3 were applied, ambient O3 in non-filtered OTCs (NF-OTCs) and -40% of ambient O3 in charcoal-filtered OTCs (CF-OTCs), during four consecutive growing cycles. At the end of each growing cycle, the marketable yield (fresh biomass) was assessed while during the growing periods, measurements of the stomatal conductance at leaf level were performed and used to define a stomatal conductance model for calculation of the phytotoxic ozone dose (POD) absorbed by the plants...

The archaeological sites near Monte Alegre, along Brazil's lower Amazon River, provide new information on the little-known activities and symbolism of South American Paleoindians toward the end of the Ice Age. While paleoindian sites like Monte Verde in Chile, or Guitarrero Cave in Peru, are located near the pacific coast, Monte Alegre lies much further inland, 680 km upriver from the mouth of the Amazon River and the Atlantic Coast. With excavated wood charcoal radiocarbon dated as early as 13,200 calibrated years ago, the hill-as a source of sandstone and quartz lithics-supplied early pioneers with adequate tools needed for colonizing the interior of the continent...

Le Carbone (LC) is a charcoal supplement, which contains a large amount of dietary fibers. Several studies suggested that charcoal supplement may be beneficial for stomach disorders, diarrhea, gas and indigestion. But no studies address whether LC intake would suppress inflammation, cell proliferation or disease progression in colitis. In the present study, the effect of LC on experimental colitis induced by dextran sulfate sodium (DSS) in mice and its possible mechanism of action were examined. A study was designed for 8days, using C57BL/6 female mice that were administered with 3% DSS in drinking water for 7days followed by another 1day consumption of normal water with or without treatment...
