Multidrug and toxic compound extrusion (MATE) transporters are ubiquitous ion-coupled antiporters that extrude structurally and chemically dissimilar cytotoxic compounds and have been implicated in conferring multidrug resistance. Here, we integrate double electron–electron resonance (DEER) with functional assays and site-directed mutagenesis of conserved residues to illuminate principles of ligand-dependent alternating access...

Placental trophoblast cells are potentially at risk from circulating endocrine-disrupting chemicals, such as bisphenol A (BPA). To understand how BPA and the reputedly more inert bisphenol S (BPS) affect the placenta, C57BL6J mouse dams were fed 200 μg/kg body weight BPA or BPS daily for 2 wk and then bred....

Wetlands and their biodiversity are constantly threatened by contaminant pollution from urbanisation. Despite evidence suggesting that snakes are good bioindicators of environmental health, the bioaccumulation of contaminants in reptiles is poorly researched in Australia.

The occurrence and potential sources of pharmaceuticals and personal care products (PPCPs) in surface waters from a large coastal city Qingdao, North China, were investigated. Forty-five compounds were analyzed by high-performance liquid chromatography-tandem mass spectrometry. The results showed that 28 compounds of PPCPs were detected. The most frequently detected compounds were atrazine, clarithromycin, nonylphenol, and bisphenol A with the detection rates > 90%.

Pine trees are used as biomonitoring agents to evaluate atmospheric polycyclic aromatic hydrocarbons (PAHs). Due to industrialization, urban construction, and rapid population growth, the city of Bursa is experiencing air pollution. In this study, PAHs were measured in pine tree branches and needles at a wastewater treatment plant site, an industrial site, and semirural site in Bursa for 12 months. The concentrations fluctuated depending on the characteristics of the areas.

Polychlorinated biphenyls (PCBs) are recognised reproductive and immune system toxicants in marine mammals mediated by endocrine-disrupting mechanisms. As with other predators, seals are exposed to elevated bioaccumulated concentrations of PCBs and other persistent organic pollutants (POPs).

Bisphenol A (BPA) is a manmade chemical that is only found in the environment due to anthropogenic activities. A total of 1150 surface freshwater samples were collected and analysed for BPA at 44 sampling sites in Canada from 2012 to 2018. The resultant concentrations ranged from 3.05 to 1888.51 ng/L. In addition, 64% of the samples were reported to be under the detection limit of the laboratory.

The heat shock transcription factor (Hsf) family, an important member in plant stress response, affects cadmium (Cd) tolerance in plants. In this study, we identified and functionally characterized a transcript of the Hsf A4 subgroup from Sedum alfredii. Designated as SaHsfA4c, the open reading frame was 1,302 bp long and encoded a putative protein of 433 amino acids containing a complete DNA-binding domain (DBD).

Emerging evidence has identified cardiovascular system as a potential target of Bisphenol A (BPA). Although a few studies have revealed the relationship between BPA and the risk of several cardiovascular diseases (CVD) outcomes and CVD risk factors, no published studies have investigated the link between urinary BPA and the risk of stroke.

Methylmercury (MeHg) is a well-known neurotoxicant; however, its role in metabolic diseases has been gaining wider attention. We have previously shown that MeHg causes metabolic alterations in Caenorhabditis elegans, leading to decreased nicotinamide adenine dinucleotide cofactor, mitochondrial dysfunction, and oxidative stress.

Bacterial resistance to antibiotics is a worrying situation in breeding which lead public health risk. So, the use of seaweed-based food supplements is attracting increasing attention because it is a alternative to antibiotics. The purpose of this paper is to determine the impact of pigs algae-food supplement on meat nutritive quality. Pig consumption survey has been achieved with 400 consumers in Abidjan.
