It causes acute and chronic systemic diseases, including gastrointestinal and cardiovascular diseases and kidney failure. However, few studies have investigated the mechanism by which Tl induces acute kidney injury (AKI). This study investigated the toxic effects of Tl on the histology and function of rat kidneys using biochemical and histopathological assays after intraperitoneal thallium sulfate administration (30 mg/kg). Five days post-administration, rats exhibited severely compromised kidney function. Low-vacuum scanning electron microscopy revealed excessive calcium (Ca) deposition in the outer medulla of Tl-loaded rats, particularly in the medullary thick ascending limb (mTAL) of the loop of Henle. Tl accumulated in the mTAL, accompanied by mitochondrial dysfunction in this segment. Tl-loaded rats showed reduced expression of kidney transporters and channels responsible for Ca²⁺ reabsorption in the mTAL. Pre-administration of the Na–K–Cl cotransporter 2 (NKCC2) inhibitor furosemide alleviated Tl accumulation and mitochondrial abnormalities in the mTAL. These findings suggest that Tl nephrotoxicity is associated with preferential Tl reabsorption in the mTAL via NKCC2, leading to mTAL mitochondrial dysfunction and disrupted Ca²⁺ reabsorption, culminating in mTAL-predominant Ca crystal deposition and AKI. These findings on the mechanism of Tl nephrotoxicity may contribute to the development of novel therapeutic approaches to counter Tl poisoning. Moreover, the observation of characteristic Ca crystal deposition in the outer medulla provides new insights into diagnostic challenges in Tl intoxication.</p></div>","PeriodicalId":8329,"journal":{"name":"Archives of Toxicology","volume":"98 12","pages":"3973 - 3986"},"PeriodicalIF":4.8,"publicationDate":"2024-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11496332/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142364226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite this, critical information on the immunomodulatory and antiestrogenic properties of most of these contaminants is still lacking. The present study aimed to identify the mycotoxins responsible for the immunosuppressive and antiestrogenic effects of a complex extract of Alternaria mycotoxins (CE) obtained by growing an Alternaria alternata strain on rice. Through a toxicity-guided fractionation procedure involving the production of CE-fractions by supercritical fluid chromatography and mycotoxin quantification by LC-MS/MS, the mycotoxins alternariol (AOH), tenuazonic acid (TeA), altertoxin I (ATX-I), and alterperylenol (ALTP) were identified as potential toxicologically relevant constituents contributing to the in vitro effects exerted by the extract. The assessment of the immunomodulatory effects, performed by applying the NF-κB reporter gene assay in THP1-Lucia™ monocytes, revealed the scarce contribution of AOH to the effects exerted by the CE. TeA showed no effect on the NF-κB pathway up to 250 µM, whereas ATX-I and ALTP suppressed the LPS-mediated pathway activation at concentrations ≥ 1 µM. The evaluation of antiestrogenic effects, performed in Ishikawa cells by applying the alkaline phosphatase assay, revealed the ability of ALTP (≥ 0.4 µM) and ATX-I (≥ 2 µM) to suppress the estrogen-dependent expression of enzyme activity.

The International Agency for Research on Cancer (IARC) has classified 3-MCPD as possibly and glycidol as probably carcinogenic to humans. The aims of the current work were to clarify the exposure to 2/3-MCPD and glycidol associated with different dietary habits (omnivore, vegan, raw-food eating), and the exposure development between 2017 and 2021 in German study participants. The questions were addressed using the daily urinary excretion of 2/3-MCPD and the hemoglobin adduct N-(2,3-dihydroxypropyl)-Val (DHP-Val) formed from glycidol as biomarkers of exposure, which were determined in two dietary studies including 36 omnivores, 36 vegans and 16 strict raw food eaters (abstaining from any heated food for at least four months). The median urinary excretion of 2- and 3-MCPD in non-smoking omnivores and vegans was 0.87 and 1.35 µg/day (2-MCPD), respectively, and 0.79 and 1.03 µg/day (3-MCPD), respectively. The 2/3-MCPD concentrations in urine samples of raw food eaters were usually below the limit of detection. The median DHP-Val levels in non-smoking vegans and omnivores were 3.9 pmol/g Hb each, and 1.9 pmol/g Hb in raw food eaters. Between 2017 and 2021, the exposure to 3-MCPD and glycidol did not change, however, the median 2-MCPD excretion decreased (p = 0.02, omnivores and vegans combined). The correlation between daily excretions of 2/3-MCPD determined 4 years apart was weak, whereas a moderate correlation was observed for DHP-Val (r_S = 0.66) in this timeframe. In conclusion, the exposure to glycidol in omnivores and vegans was alike, whereas the 2/3-MCPD exposure was somewhat (albeit not significantly) higher in vegans. While 2/3-MCPD were hardly detectable in urine samples of raw food eaters, the median DHP-Val level (about 50% of those in omnivores) indicates a glycidol source independent of the dietary exposure.</p>","PeriodicalId":8329,"journal":{"name":"Archives of Toxicology","volume":" ","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142340112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hydroxyzine (HZ) is a first-generation antihistamine drug with a sedative effect that disrupts cognitive function and affects the ability to drive motor vehicles. Enzymatic oxidation of the hydroxy-methyl group to the carboxyl group leads to the formation of its main metabolite—cetirizine (CZ). CZ is the active substance of antiallergic drugs. Because it does not cross the BBB (blood–brain barrier) easily, it is less likely to cause drowsiness or affect memory and impair cognitive function. Therefore, in criminal studies, it is often important what medication had been taken by a person involved, e.g., in a car accident, HZ or CZ. The analysis of both antihistamine drugs is challenging, as usually very low concentrations of the compound of interest need to be determined. Thus, an ultra-sensitive UHPLC–QqQ-MS/MS method was developed for simultaneous determination of HZ and CZ in biological fluid samples. The lower limit of quantification (LOQ) for HZ and CZ was calculated as 0.345 and 0.3696 ng/mL, respectively. Together with a reduced sample volume to 200 μL, it makes the developed method suitable for a sensitive multidrug forensic toxicological analysis. Samples were extracted with simple and fast liquid–liquid extraction (ethyl acetate, pH 9). The present method for the determination of HZ and CZ in human blood proved to be simple, fast, selective, and sensitive. The quantification by LC–MS/MS was successfully applied to the samples coming from 28 authentic biological fluids (blood, urine, vitreous humor, bile and stomach content), both antemortem and postmortem. The performed studies confirm that the developed method is characterized by a high extraction efficiency. Its accuracy, reproducibility, simplicity, and selectivity suggest its application in clinical, toxicological, and forensic laboratories.</p></div>","PeriodicalId":8329,"journal":{"name":"Archives of Toxicology","volume":"98 12","pages":"3987 - 4012"},"PeriodicalIF":4.8,"publicationDate":"2024-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11496346/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142340109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
