Concentrations of Ag, Al, Ba, Ca, Cd, Co, Cu, Cr, Cs, Fe, Ga, Hg, K, Mg, Mn, Mo, Na, Ni, Pb, Rb, Se, Sb, Sr, V, Tl and Zn have been determined in the whole fruiting bodies as well as separately in caps and stalks of Poison Pax collected from three geographically distant sites across Poland. The elements were determined using ICP-MS, ICP-OES, HG-AAS and CV-AAS, respectively. Based on arithmetic mean and median values for Poison Pax specimens from the Lezno site the elements such as Ag, Co, Cr, Cs, Mn, Mo, K, Pb, Rb, Sb, Se, V and Tl occur at similar concentration both in the caps and stalks, while for Cd, Cu, Hg, Mg and Zn around two-fold greater concentrations were noted in caps than stalks (cap/stalk concentration quotient > 1). Cs, Cd, Ni and Rb occurred at much greater concentration in specimens collected from the Kłodzka Hollow in the Sudety Mountains when compared to the lowland site (Mann-Whitney U-test), and slightly greater values were noted also for Cr, Mo and Rb, while for Ca, Co, Mg and Mn were smaller The results provide useful environmental and biological baseline level of information for metallic elements of Poison Pax.

Pan-European atmospheric lead pollution, enhanced blood lead levels, and cognitive decline from Roman-era mining and smelting.
Proc Natl Acad Sci U S A

Ancient texts and archaeological evidence indicate substantial lead exposure during antiquity that potentially impacted human health. Although lead exposure routes were many and included the use of glazed tablewares, paints, cosmetics, and even intentional ingestion, the most significant for the nonelite, rural majority of the population may have been through background air pollution from mining and smelting of silver and lead ores that underpinned the Roman economy. Here, we determined potential health effects of this air pollution using Arctic ice core measurements of Roman-era lead pollution, atmospheric modeling, and modern epidemiology-based relationships between air concentrations, blood lead levels (BLLs), and cognitive decline.

Background: Photobiomodulation has exhibited promise in mitigating the local effects induced by Bothrops snakebite envenoming; however, the mechanisms underlying this protection are not yet fully understood. Herein, the effectiveness of photobiomodulation effects on regenerative response of C2C12 myoblast cells following exposure to Bothrops jararacussu venom (BjsuV), as well as the mechanisms involved was investigated.
Methodology/principal Findings: C2C12 myoblast cells were exposed to BjsuV (12.
Therapeutic Potential of Silymarin in Mitigating Paclitaxel-Induced Hepatotoxicity and Nephrotoxicity: Insights into Oxidative Stress, Inflammation, and Apoptosis in Rats.
Balkan Med J
May 2024
Clinic of General Surgery, University of Health Sciences Türkiye, Erzurum Regional Training and Research Hospital, Erzurum, Türkiye.
Background: Paclitaxel (PAX) is a widely used chemotherapy drug for various cancer types but often induces significant toxicity in multiple organ systems. Silymarin (SIL), a natural flavonoid, has shown therapeutic potential due to its multiple benefits.
Aims: To evaluate the therapeutic efficacy of SIL in mitigating liver and kidney damage induced by PAX in rats, focusing on oxidative stress, inflammation, and apoptosis pathways.
Analysis of Five Mushroom Toxins in Blood by UPLC-HRMS.

October 2021
Hebei Key Laboratory of Forensic Medicine, Collaborative Innovation Center of Forensic Medical Molecular Identification, Forensic Identification Center of Hebei Medical University, College of Forensic Medicine, Hebei Medical University, Shijiazhuang 050017, China.
Objectives: To develop a method for the simultaneous and rapid detection of five mushroom toxins (α-amanitin, phallacidin, muscimol, muscarine and psilocin) in blood by ultra-high performance liquid chromatography-high resolution mass spectrometry (UPLC-HRMS).
Methods: The blood samples were precipitated with acetonitrile-water solution(∶=3∶1) and PAX powder, then separated on ACQUITY Premier C column, eluted gradient. Five kinds of mushroom toxins were monitored by FullMS-ddMS/positive ion scanning mode, and qualitative and quantitative analysis was conducted according to the accurate mass numbers of primary and secondary fragment ions.
Fatal Immunohaemolysis after the Consumption of the Poison Pax Mushroom: A Focus on the Diagnosis of the Paxillus Syndrome with the Aid of Two Case Reports.
Diagnostics (Basel)

Institute of Forensic Medicine, University of Munich, Nussbaumstrasse 26, 80336 Munich, Germany.
This retrospective report focuses on the diagnosis of the Paxillus syndrome, based on two fatal cases of haemolysis following the consumption of . These mushrooms are still consumed regularly, despite earlier reports of life-threatening autoimmune haemolytic anaemia. Such cases are nevertheless rare, and thus far no toxin could be identified that causes this unusual form of mushroom poisoning.
