Background. Despite aggressive intensive medical management acute liver failure (ALF) may require high-urgency liver transplantation (LTx). Available prognostic scores do not apply for all patients; reliable tools to identify individuals in need of LTx are highly required. The liver maximum function capacity test (LiMAx) might represent an appropriate option. Referring to a case of ALF after Am...

Of the more than 5000 species of mushrooms known, 100 types are toxic and approximately 10% of these toxic types can cause fatal toxicity. A type of mushroom called Amanita phalloides is responsible for 95% of toxic mushroom poisonings. In this article, we report 2 cases of mushroom poisonings caused by Lactarius volemus, known as Tirmit by the local people. The patient and his wife were admitt...

There are limited data on amperometric biosensors (ABSs) for L-arginine (Arg) determination based oxidases that produce hydrogen peroxide (H2O2) as a byproduct of enzymatic reaction, and artificial peroxidases (POs) decomposition H2O2. The most frequently proposed Arg-sensitive oxidase-based ABSs contain at least two enzymes in the bioselective layer; this complicates procedure increases cost a...

Phalloidin, a toxin from the plant Amanita phalloides, irreversibly polymerizes actin filaments and causes cholestasis. Three-dimensional structural changes induced by phalloidin in the bile canaliculi and the intra-acinar localization of these changes were studied in the rat liver by scanning and transmission electron microscopy. After 3 days of treatment, canalicular changes appeared mainly i...

[Phe4, Val6] antamanide, a synthetic, biologically active analog of the cyclic decapeptide antitoxin isolated from Amanita phalloides, has been crystallized from a mixture of n-hexane and methyl acetate, and its conformation has been established by the direct method of x-ray diffraction analysis, i.e., without the benefit of any heavy atom. The uncomplexed molecule contains a 2-fold rotation ax...

We collected nearly 70 specimens of Amanita species during a diversity study of Korean mushrooms conducted in 2012. In this study, we primarily investigated 23 Amanita specimens belonging to sections Amanita and Vaginatae. Based on sequence data of the internal transcribed spacers and partial large subunit of ribosomal RNA and morphological characteristics, we identified the following 15 phylog...

The heavy metals (Cd, Cr, Ni, Pb, Zn, Cu, Fe, Mn) content of some edible wild mushrooms (Amanita caesarea, Amanita rubescens, Amanita vaginata, Amanita spissa) and soil samples, of ten sites from Dambovita county Romania, were analyzed. Elements concentrations were determined by Flame Atomic Absorption (FAA) spectrometry and Energy Dispersive X-ray spectrometry (EDXRF) in 40 samples of Amanita ...
