Greater celandine (
L.) is used internally as a herbal remedy besides external applications. It was supposed that the elements besides organic compounds in greater celandine also have favourable effect as adjuvants, therefore, the aim of the study was to evaluate the bioavailability of the elements. The element transfer through the gastrointestinal system was measured by in vitro model from the pressed extract into buffer solutions with different pH (stomach pH=1.1, intestine pH=2.8, plasma pH=7.5). It was stated that the elements (Al, B, Ba, Ca, Cu, Fe, Mg, Mn, S, Zn) were able to be absorbed through the stomach-bowel system, since they passed through the membrane. The transfer of the elements from the latex into the different buffer solutions greatly depends on the element and the pH of applied buffer solution. The transfer of the elements from the latex ranged between 0.9% (Ca into buffer solution pH=7.5) and 59.3% (B into buffer solution pH=2.8). The transfer of the highest amount of elements was observed in the case of buffer solution pH=2.8, and less transferable elements were Ca with 33.64% and Mg with 33.89% of the initial value. On the basis of results, it can be stated that the elements are able to transfer through the gastrointestinal system and may have adjuvant effects.

Contents of 23 elements were estimated in pilei and stipes of different varieties of three cultivated mushrooms (Agaricus bisporus, Pleurotus ostreatus and Lentinula edodes). The average data of element's composition were evaluated and compared to each other and to the average composition of the wild growing fungi. The high and remarkable K (and partly P) contents are postulated, first of all to Agaricus bisporus. The Ca and Mg contents are in general relative stable and balanced. Copper and Mn as valuable microelements required to the normal human biochemical processes have important quantities. Low sodium levels are characteristic to all examined mushrooms, the lowest values were found for Pleurotus ostreatus. The high K and the low Na contents mean a valuable rate of K and Na (to all species) in the human nutrition of some patients. Selenium level of Agaricus bisporus (2.3-2.7 mg kg-1, d.m.) may improve the Se-supply of the customers. Our data demonstrate clearly that the Cd and As levels of three species are reassuringly low and do not present toxicological risk. Some elements have higher contents in pileus than in stipes (16 elements in Agaricus, 14 in Lentinula, and only 10 elements in Pleurotus), while other ones have an opposite distribution (7, 9 and 13, respectively). Four elements (K, P, Ca and Mg) give 97-98% of the total element concentration of the three cultivated mushrooms, whereas the other 19 elements give only 2-3%.
The long quest to detect SuperHeavy Elements that might exist in nature or to artificially synthesize them at accelerators is briefly reviewed. The very recent reports of the production and detection of the SuperHeavy Elements 114, 116, and 118 at accelerators are discussed. The implications of these discoveries and the prospects for the existence and discovery of additional heavy elements are considered.
hypothesis’, it would be an interesting story in science and scientometrics, so we really met all elements in our study, e.g., spindles, sleeping beauties, and princes. Let's call the phenomenon as all-elements sleeping beauty.
