An increasing number of studies have clarified that ferroptosis plays a vital role in neurodegenerative diseases, which is characterized by the accumulation of Fe2+, lipid peroxidation, and alteration of mitochondrial structure. However, whether ferroptosis is involved in nerve injury caused by lead exposure remains unclear. In this study, HT22 cells and mice were treated with lead acetate to investigate the role of ferroptosis in lead neurotoxicity.

Arsenic is widely present in nature and is a class I carcinogen confirmed by the World Health Organization and the International Agency for Research on Cancer. The liver is responsible for biotransformation in the body and is one of the major organs where arsenic accumulates in the body, but the mechanisms of arsenic-induced abnormal DNA damage repair pathways in the liver are still unclear.

Journal of Applied Microbiology, Accepted Article. Aims This study aims at immobilization of fungal mutants on nanosilica-carriers for designing efficient biosorbents as a significant new technology for decontamination practices and maximizing their heavy metal (HM) sorption proficiency through the experimental design methodology. Materials and Results Endophytic fungal mutant strains, Chaetomium globosum El26 mutant and Alternaria alternata

Arsenic is a persistent environmental contaminant that humans are exposed to primarily through contaminated water supplies. Arsenic has been shown to have numerous immunomodulatory effects, including deleterious effects on T cell function. However, the effect of arsenic on human T cell function in the context of influenza infection remains poorly characterized.

The investigation of chemical speciation of primary toxic metal(loid)s (Cd, Pb, and As) in soil profile in nonferrous metal smelting site is a key to the assessment of their mobility ch

Arsenic (As) stress provokes various toxic effects in plants that disturbs its photosynthetic potential and hampers growth. Ethylene and selenium (Se) have shown regulatory interaction in plants for metal tolerance; however, their synergism in As tolerance through modification of the antioxidant enzymes and hormone biosynthesis needs further elaboration.

As a kind of environmental pollutant, heavy metal Cadmium (Cd) exists widely in the environment. It is well known that Cd can accumulate and cause damage in liver, kidney and other organs. However, there are few studies on the immune cytotoxicity of Cd to fish. In particular, there are few studies on the toxicity of Cd to the head kidney lymphocytes of common carp. In order to further explore these mechanisms, we established an Cd exposure model in vitro.

Cadmium (Cd) pollution has detrimental effects on the ecological environment and human health. Currently, phytoremediation is considered an environmentally friendly way to remediate Cd pollution.

Olive farming is one of the key agricultural activities in Jordan, where nearly 70% of the cultivated land in Jordan is covered with olive trees. Olive harvesting generates massive quantities of agricultural waste which will be an environmental burden if not managed properly. The present study introduces the use of novel co-processed biomass extracted from the olive tree leaves for the adsorption of lead from contaminated water.

Toxoplasma gondii is a zoonotic parasite that infects the brain of humans and causes cerebral toxoplasmosis. The recommended drugs for the treatment or prophylaxis of toxoplasmosis are pyrimethamine (PY) and sulfadiazine (SZ), which have serious side effects. Other drugs available for toxoplasmosis are poorly tolerated.

The oligopeptide transporter (OPT) family is a group of proton-coupled symporters that play diverse roles, including metal homeostasis. However, little is known about this family of peanuts.

Lead smelting slag (LSS) is a hazardous waste containing heavy metals (Cr, Ni, Cu, Zn, As, and Pb) and its improper disposal may cause irreparable damage to the ecosystem. Cementitious materials prepared with LSS can be used in construction fields and hazardous heavy metals are also solidified in prepared cementitious materials.

The toxic heavy metal cadmium (Cd) is easily absorbed and accumulated in crops and affects human health through the food chains. Sunflower (Helianthus annuus L.) is a globally important oil crop. In this study, two sunflower cultivars 62\3 (high Cd) and JB231AC (low Cd), were chosen to compare physiological and transcriptomic responses at different Cd concentrations (0, 25, 50, and 100 μM). The results showed that JB231AC had better Cd tolerance than 62\3.

Mycolic acids are the key constituents of mycobacterial cell wall, which protect the bacteria from antibiotic susceptibility, helping to subvert and escape from the host immune system. Thus, the enzymes involved in regulating and biosynthesis of mycolic acids can be explored as potential drug targets to kill Mycobacterium tuberculosis (Mtb).

Cadmium pollution is a serious threat to the soil environment. The application of bio-based fertilizers in combination with beneficial microbial agents is a sustainable approach to solving Cd pollution in farm soil. The present study investigated the effects of co-application of a Cd-immobilizing bacterial agent and two fermented organic fertilizers (fermentative edible fungi residue; fermentative cow dung) on Houttuynia cordata and its microbial communities in a Cd-polluted field.

Lithium-ion battery technology is one of the innovations gaining interest in utility-scale energy storage. However, there is a lack of scientific studies about its environmental performance. This study aims to evaluate the environmental impacts of lithium-ion batteries and conventional lead-acid batteries for stationary grid storage applications using life cycle assessment.

To investigate the maternal genetic effects of cadmium (Cd) -induced apoptotic in ovarian granulosa cells (OGCs). Herein, pregnant Sprague-Dawley (SD) rats were treated with CdCl2 from day 1 to day 20, F1 and F2 female rats were mated with untreated males to produce F2 and F3 generations. Under this model, significant apoptotic changes were observed in F1 OGCs induced by Cd (Liu et al., 2021).

The goal of this study was to analyze whether mitochondria-associated endoplasmic reticulum membrane (MAMs) dysfunction mediated arsenic (As)-evoked pulmonary ferroptosis and acute lung injury (ALI).

Potentially toxic elements (PTEs) such as cadmium (Cd), lead (Pb), chromium (Cr), and arsenic (As), polluting the environment, pose a significant risk and cause a wide array of adverse changes in plant physiology. Above threshold accumulation of PTEs is alarming which makes them prone to ascend along the food chain, making their environmental prevention a critical intervention. On a global scale, current initiatives to remove the PTEs are costly and might lead to more pollution.

Mosses are one of the earliest diverging land plants that adapted to living on land. The BURP domain-containing proteins (BURP proteins) are plant-specific proteins that appeared when plants shifted from aquatic environments to land. Phylogenetic analysis revealed that the BURP domain of higher plants is originated from lower land plants and divergent because of motif conversion.

Amiodarone (AMD) is an antiarrhythmic drug that induces idiosyncratic toxicity. Environmental pollutants, including heavy metals, could interact with its toxicity by affecting pharmacokinetics and pharmacodynamics. Other levels of interaction could exist in yeast, such as oxidative stress and the general stress response. In this study, we investigated the interaction of mercury chloride (HgCl2) and cadmium chloride (CdCl2) with AMD toxicity on Saccharomyces cerevisiae.

by Michelle Gende, Martina Schmeling In this work, an analytical method was developed for the determination of lead and cadmium in biological samples using graphite furnace atomic absorption spectrometry. Escherichia coli (E. coli) was chosen as model substance for this purpose as it is readily available in most laboratories and can be quickly and easily prepared with a high turnaround rate.

At present, foodborne diseases (FBDs) caused by bacteria are gradually increasing every year, and the development of new antibiotics is an urgent necessity for human beings. To find novel antibacterial compounds, three sponge-derived fungal strains (SCSIOS02F40, F46, and F49) were investigated. As a result, Alternaria sp.

Journal of Food Science, EarlyView. Rice is a recognized source of cadmium (Cd) exposure. In this study, a total of 102 rice samples were obtained from main producing rice regions of China, and the bioavailability of Cd in rice were assessed by using an in vitro digestion method combined with a Caco-2 cell monolayer model.
