Background: Monitoring of human exposure to mercury is important due to its adverse health effects. This study aimed to determine the extent of mercury exposure among mothers and their children in Ireland, and to identify factors associated with elevated levels. It formed part of the Demonstration of a study to Coordinate and Perform Human Biomonitoring on a European Scale (DEMOCOPHES) pilot biomonitoring study.

Methods: Hair mercury concentrations were determined from a convenience sample of 120 mother/child pairs. Mothers also completed a questionnaire. Rigorous quality assurance within DEMOCOPHES guaranteed the accuracy and international comparability of results.

Results: Mercury was detected in 79.2% of the samples from mothers, and 62.5% of children's samples. Arithmetic mean levels in mothers (0.262 µg/g hair) and children (0.149 µg /g hair) did not exceed the US EPA guidance value. Levels were significantly higher for those with higher education, and those who consumed more fish.

Conclusions: The study demonstrates the benefit of human biomonitoring for assessing and comparing internal exposure levels, both on a population and an individual basis. It enables the potential harmful impact of mercury to be minimised in those highly exposed, and can therefore significantly contribute to population health.

Nematode controlling effects and safety tests of Duddingtonia flagrans biological preparation in sheep.

Sci Rep

Rui Pu Agricultural Technology Co., Ltd, Hohhot, Inner Mongolia, People's Republic of China.

Duddingtonia flagrans is a nematode-trapping fungus that is widely used to control parasitic nematodes in livestock. After oral ingestion and passage through the digestive tract of animals, this microorganism captures nematodes in feces. Although many researchers have examined the safety of this fungus for humans, animals, and the environment, few reports have discussed the safety of nematode-trapping D.

Assessment of the pathogenicity of Y. enterocolitica B1A isolates from San Luis, Argentina.

Yersinia enterocolitica, a bacterial enteropathogen that produces a variety of clinical manifestations in humans, includes six biotypes (B), called 1A, 1B, 2, 3, 4 and 5 and about 70 serotypes. The biotypes exhibit diverse pathogenic potential; while 1B and 2-5 may show ability to produce clinical symptoms due to the presence of chromosomal and plasmid (pYV) virulence genes, B1A is supposed a non-pathogenic biotype since it lacks pYV plasmid. Therefore, although B1A strains cause diarrhea in humans, their pathogenic potential has not yet been extensively studied.

Miniaturized Liver Disease Mimics to Gain Insights into MMP Expression during Disease Progression.

ACS Biomater Sci Eng

Centre for Biomedical Engineering, Indian Institute of Technology Delhi, Hauz Khas, New Delhi 110016, India.

Nonalcoholic fatty liver disease (NAFLD) encompasses a spectrum of liver conditions, ranging from hepatic steatosis to steatohepatitis, fibrosis, and severe outcomes such as cirrhosis or cancer. The progression from hepatic steatosis to fibrosis involves significant extracellular matrix (ECM) remodeling, characterized by increased collagen deposition and cross-linking of ECM proteins, causing increased tissue stiffness and altered MMP expression patterns. Dysregulated MMP expression and extracellular acidosis are key contributors to NAFLD progression.

Background: Insulin resistance and the G allele of rs738409 interact to create a greater risk of metabolic dysfunction-associated steatotic liver disease.

Objective: This study aims to confirm that one promising way to reduce insulin resistance is by following a very low-carbohydrate (VLC) dietary pattern.

Methods: Adults with rs738409-GG or -CG with liver steatosis and elevated liver function tests, were taught an ad libitum VLC diet, positive affect and mindful eating skills, goal setting, and self-monitoring and given feedback and coaching for 4 months.

Permeable, Stretchable, and Recyclable Cellulose Aerogel On-Skin Electronics for Dual-Modal Sensing and Personal Healthcare.

ACS Nano

January 2025

CAS Key Laboratory of Mechanical Behavior and Design of Materials, Department of Modern Mechanics, University of Science and Technology of China, Hefei, Anhui 230027, PR China.

Flexible on-skin electronics present tremendous popularity in intelligent electronic skins (e-skins), healthcare monitoring, and human-machine interfaces. However, the reported e-skins can hardly provide high permeability, good stretchability, and large sensitivity and are limited in long-term stability and efficient recyclability when worn on the human body. Herein, inspired from the human skin, a permeable, stretchable, and recyclable cellulose aerogel-based electronic system is developed by sandwiching a screen-printed silver sensing layer between a biocompatible CNF/HPC/PVA (cellulose nanofiber/hydroxypropyl cellulose/poly(vinyl alcohol)) aerogel hypodermis layer and a permeable polyurethane layer as the epidermis layer.
