Methylmercury (MeHg) is the most toxic form of mercury and can accumulate in the cells of marine organisms, such as fish, causing adverse effects on various physiological functions. This study examined MeHg accumulation and its toxicological role in antioxidant defenses in tissues, including the liver, gills, and muscle of flounder (Paralichthys olivaceus) juveniles.

Cancerous and non-cancerous cells secrete exosomes, a type of nanovesicle known to carry the molecular signature of the parent for intercellular communications. Exosomes secreted by tumor cells carry abnormal DNA, RNA, and protein molecules that reflect the cancerous status. DNA is the master molecule that ultimately affects the function of RNA and proteins. Aberrations in DNA can potentially lead a cell to malignancy.

Multidrug-resistant (MDR; resistance to >3 antimicrobial classes) Salmonella enterica serovar I 4,[5],12:i:- strains were linked to a 2015 foodborne outbreak from pork. Strain USDA15WA-1, associated with the outbreak, harbors an MDR module and the metal tolerance element Salmonella Genomic Island 4 (SGI-4). Characterization of SGI-4 revealed that conjugational transfer of SGI-4 resulted in the mobile genetic element (MGE) replicating as a plasmid or integrating into the chromosome.

Carotenoid isolated from the leaves of Spondias mombim; astaxanthin, β‐carotene‐15,15ʹ‐epoxide, and 7,7ʹ,8,8ʹ‐tetrahydro‐β‐β‐carotene demonstrate selective inhibition of XIAP by hydrophobic interactions within the domains of BIR2 and BIR3.

Grass cell walls have hydroxycinnamic acids attached to arabinosyl residues of arabinoxylan (AX) and certain BAHD acyltransferases are involved in their addition. In this study, we characterized one of these BAHD genes in the cell wall of the model grass Setaria viridis. RNAi silenced lines of S. viridis (SvBAHD05) presented a decrease of up to 42% of ester‐linked p‐coumarate (pCA) and 50% of pCA‐arabinofuranosyl, across three generations.

Continuous occupational exposure to spent engine oil (SEO) poses physiological risks to humans, especially to automobile mechanics. This study investigated the physiological effects of SEO-contaminated soil in a male Wistar rat model. Animals were dermally exposed to soil contaminated with SEO for 120 consecutive days and compared with rats exposed to uncontaminated soil (negative control).

In this essay we investigate mainly 18 pesticide residues with different chemical structures in fresh vegetables, including organochlorine pesticides, organophosphorus pesticides, carbamate pesticides and pyrethroid pesticides. At the same time, it is estimated that the potential health risks for residents. A total of 313 samples were collected from 12 kinds of vegetables from Changchun, the capital of Jilin Province,China.

An open tubular capillary column (100 μm internal diameter and 120 cm length) was first fabricated with N‐phenylacrylamide and styrene copolymer layer on the inner surface by in situ one‐pot strategy, while ethylene dimethacrylate was used as the cross‐linker. The pretreated silica‐fused capillary was reacted with 3‐trimethoxysilyl propyl methacrylate to attach a double bond ligand onto the inner surface of the capillary.

Mercury (Hg), particularly as methylmercury (MeHg), is a nonessential, persistent, and bioaccumulative toxic element with high biomagnification capacity and is considered a threat to marine environments. We evaluated total Hg concentrations in liver, kidney, and brain in 62 individuals of 9 bird species linked to marine ecosystems from western Mediterranean admitted in a Wildlife Rehabilitation Center (WRC) (Alicante, Spain, 2005–2020).

The presence of chemical contaminant in alcoholic beverages is a widespread and notable problem with potential implications for human health. With the complexity and wide variation in the raw materials, production processes, and contact materials involved, there are a multitude of opportunities for a diverse host of undesirable compounds to make their way into the final product—some of which may currently remain unidentified and undetected.

Several subsets of regulatory CD4+ T cells (CD4+ Tregs) have been described in peripheral blood and tumor microenvironment of breast cancer (BC) patients and may play a role in the progression of BC. High-risk human papilloma virus (HR-HPV) has a causal role in cervical, head, and neck tumors but the role of HR-HPV in evoking neoplasia in BC is still unclear.

Assisted phytoremediation using amendments is a cost-effective and environmentally friendly approach to control soil pollution. However, amendment type, combination and application rate can influence process effectiveness. In the present study, the effect of the association of red mud and carbon-based amendments on the physicochemical properties of a former mine soil as well as the growth and metal(loid) uptake of Trifolium repens was investigated.
