The effect of an intervention to reduce aflatoxin consumption from 6 to 18 mo of age on length-for-age z-scores in rural Tanzania: a cluster-randomized trial.

Background: Linear growth faltering continues to negatively affect children in low- and middle-income countries and is associated with poor cognitive, developmental, and educational outcomes. Laboratory and observational data suggest that aflatoxin (AF) is a contributor to stunting.

Objective: The Mycotoxin Mitigation Trial was a cluster-randomized, community-based 2-group trial conducted in Kongwa District, Tanzania, between 2018 and 2020.

Reactions of citrinin with amino compounds modelling thermal food processing.

Citrinin (CIT) is a nephrotoxic mycotoxin, produced by several species of Penicillium, Aspergillus, and Monascus. The foodstuffs most frequently contaminated with CIT include cereals, cereal products, and red yeast rice. Studies on the occurrence of CIT in food have shown that the CIT concentrations in processed cereal-based products are generally lower than in unprocessed industry cereal samples.

Signatures of hierarchical temporal processing in the mouse visual system.

A core challenge for the brain is to process information across various timescales. This could be achieved by a hierarchical organization of temporal processing through intrinsic mechanisms (e.g.

Population dynamics and spatial structure of the grey rockcod (Lepidonotothen squamifrons) in the vicinity of Heard Island and the McDonald Islands.

The grey rockcod, Lepidonotothen squamifrons is an important prey species for seals, penguins and Patagonian toothfish (Dissostichus eleginoides) in the Southern Ocean. Across the Kerguelen Plateau, the species was fished to commercial extinction (ca. 152 000 tonnes between 1971 and 1978) prior to the declaration of the French Exclusive Economic Zone in 1979 and the Australian Fishing Zone in 1981.

Role of albumin in the metabolism and excretion of ochratoxin A.

Ochratoxin A (OTA) is known to be strongly bound to serum albumin, but it remains unknown how albumin affects its metabolism and kinetics. To close this gap, we used a mouse model, where heterozygous albumin deletion reduces serum albumin to concentrations similar to hypoalbuminemic patients and completely eliminates albumin by a homozygous knockout. OTA and its potential metabolites (OTα, 4-OH-OTA, 7'-OH-OTA, OTHQ, OP-OTA, OTB-GSH, OTB-NAC, OTB) were time-dependently analyzed in plasma, bile, and urine by LC-MS/MS and were compared to previously published hepatotoxicity and nephrotoxicity data.

Integrated data from intravital imaging and HPLC-MS/MS analysis reveal large interspecies differences in AFB metabolism in mice and rats.

Large interspecies differences between rats and mice concerning the hepatotoxicity and carcinogenicity of aflatoxin B (AFB) are known, with mice being more resistant. However, a comprehensive interspecies comparison including subcellular liver tissue compartments has not yet been performed. In this study, we performed spatio-temporal intravital analysis of AFB kinetics in the livers of anesthetized mice and rats.

Co-occurrence of T-2 and HT-2 Mycotoxins and α and β Anomers of Their Glucosides in Wheat and Oat Grains.

The aim of this study was to simultaneously determine T-2 and HT-2 toxins and the α and β anomers of their glucosides to assess their content in wheat and oat grains harvested in Poland (2020-2022). Of 298 wheat samples, only 14 (5%) contained the sum of the T-2 and HT-2 toxins (average 34.2 μg/kg; 10.

Comparative metabolism of aflatoxin B in mouse, rat and human primary hepatocytes using HPLC-MS/MS.

Aflatoxin B (AFB) is a highly hepatotoxic and carcinogenic mycotoxin produced by Aspergillus species. The compound is mainly metabolized in the liver and its metabolism varies between species. The present study quantified relevant AFB- metabolites formed by mouse, rat, and human primary hepatocytes after treatment with 1 µM and 10 µM AFB.

[LGBTQIA+ people: care issues in the emergency department].

Visits to the emergency department are often a difficult time for LGBTQIA+ people, mainly because of the frequent discrimination in healthcare environments and the lack of knowledge of medical and nursing staff. This article begins by presenting some epidemiological features, before discussing specific issues such as contraception and fertility, hormone therapy, sexually transmitted infections, surgical complications, psychiatric pathologies, and traumatology, from the perspective of the emergency physician. Finally, suggestions for further reflection and improvement are proposed.

The contribution of anthropology to the study of Open Dialogue: ethnographic research methods and opportunities.

When Open Dialogue diversifies internationally as an approach to mental healthcare, so too do the research methodologies used to describe, explain and evaluate this alternative to existing psychiatric services. This article considers the contribution of anthropology and its core method of ethnography among these approaches. It reviews the methodological opportunities in mental health research opened up by anthropology, and specifically the detailed knowledge about clinical processes and institutional contexts.

Degradation products of aflatoxin M (AFM) formed by high voltage atmospheric cold plasma (HVACP) treatment.

Cold plasma technology is a novel non-thermal technology that has shown promising results for food decontamination and improving food safety. This study is a continuation of a previous investigation of the treatment of AFM-contaminated skim and whole milk samples by HVACP. Previous research has shown HVACP is effective in degrading aflatoxin M (AFM) in milk.

Inhibition of cytochrome P450 enhances the nephro- and hepatotoxicity of ochratoxin A.

The mycotoxin ochratoxin A (OTA) is a contaminant in food that causes nephrotoxicity and to a minor degree hepatotoxicity. Recently, we observed that OTA induces liver damage preferentially to the cytochrome P450 (CYP)-expressing pericentral lobular zone, similar to hepatotoxic substances known to be metabolically toxified by CYP, such as acetaminophen or carbon tetrachloride. To investigate whether CYP influences OTA toxicity, we used a single dose of OTA (7.

Hypoalbuminemia affects the spatio-temporal tissue distribution of ochratoxin A in liver and kidneys: consequences for organ toxicity.

Hypoalbuminemia (HA) is frequently observed in systemic inflammatory diseases and in liver disease. However, the influence of HA on the pharmacokinetics and toxicity of compounds with high plasma albumin binding remained insufficiently studied. The 'lack-of-delivery-concept' postulates that HA leads to less carrier mediated uptake of albumin bound substances into hepatocytes and to less glomerular filtration; in contrast, the 'concept-of-higher-free-fraction' argues that increased concentrations of non-albumin bound compounds facilitate hepatocellular uptake and enhance glomerular filtration.

Cumulative effects of piscivorous colonial waterbirds on juvenile salmonids: A multi predator-prey species evaluation.

Analysis of mold and mycotoxins in naturally infested indoor building materials.

Health issues of residents of mold-infested housing are reported on a regular basis, and reasons for the arising impairments can be manifold. One possible cause are the toxic secondary metabolite produced by indoor microfungi (mycotoxins). To enable a more thorough characterization of the exposure to mycotoxins in indoor environments, data on occurrence and quantities of mycotoxins is essential.

Nanomechanical variability in the early evolution of vertebrate dentition.

Conodonts are an extinct group of primitive jawless vertebrates whose elements represent the earliest examples of a mineralized feeding apparatus in vertebrates. Their relative relationship within vertebrates remains unresolved. As teeth, conodont elements are not homologous with the dentition of vertebrates, but they exhibit similarities in mineralization, growth patterns, and function.

Assessment of multiple mycotoxin exposure and its association with food consumption: a human biomonitoring study in a pregnant cohort in rural Bangladesh.

Aflatoxins (AFs), ochratoxin A (OTA), citrinin (CIT), fumonisin B (FB), zearalenone (ZEN), and deoxynivalenol (DON) are mycotoxins that may contaminate diets, especially in low-income settings, with potentially severe health consequences. This study investigates the exposure of 439 pregnant women in rural Bangladesh to 35 mycotoxins and their corresponding health risks and links their exposure to certain foods and local stimulants. Overall, 447 first-morning urine samples were collected from pregnant women between July 2018 and November 2019.

The BrainScaleS-2 Accelerated Neuromorphic System With Hybrid Plasticity.

Since the beginning of information processing by electronic components, the nervous system has served as a metaphor for the organization of computational primitives. Brain-inspired computing today encompasses a class of approaches ranging from using novel nano-devices for computation to research into large-scale neuromorphic architectures, such as TrueNorth, SpiNNaker, BrainScaleS, Tianjic, and Loihi. While implementation details differ, spiking neural networks-sometimes referred to as the third generation of neural networks-are the common abstraction used to model computation with such systems.

Detection of Mycotoxins in Highly Matrix-Loaded House-Dust Samples by QTOF-HRMS, IM-QTOF-HRMS, and TQMS: Advantages and Disadvantages.

The analysis of (trace) contaminants in environmental samples represents an important tool for exposure assessment and for the evaluation of potential risks to human health. Currently, mass spectrometric detection using triple quadrupole (TQMS) systems is the established method of choice. However, screening methods using high resolution mass spectrometry (HRMS) find increasing application as they provide advantages such as enhanced selectivity.
