Environmental pollution often releases multiple contaminants resulting in as yet largely uncharacterized additive toxicities. Cadmium (Cd) is a widespread pollutant that induces nephrotoxicity in animal models and humans.

The presented study sheds light on the applicability of inductively coupled plasma optical emission spectrometry (ICP-OES) for the multielement analysis of naturally obtained water. The technique mainly focused on the determination of cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb), and zinc (Zn) which are considered to be toxic metals and have deteriorating health impacts.

Antimicrobial resistance (AMR) circulates through humans, animals, and the environments, requiring a One Health approach. Recently, urban sewage has increasingly been suggested as a hotspot for AMR even in high-income countries (HICs), where the water sanitation and hygiene infrastructure are well-developed. To understand the current status of AMR in wastewater in a HIC, we reviewed the epidemiological studies on AMR in the sewage environment in Japan from the published literature.

by Junho Cho, William F. C. Rigby, Ambrose L. Cheung Patients with cystic fibrosis (CF) often suffer recurrent bronchial bacterial infections that lead to deterioration of lung function over time. The infections in CF patients are often due to S. aureus and P. aeruginosa that colonize the airways. Significantly, methicillin-resistant S.

Cadmium (Cd) causes pervasive harm on human health as a poisonous heavy metal. This study proposed a surface-enhanced Raman spectroscopy (SERS) approach using sodium alginate (SA) as green reductant in combination with edge enrichment and chemometrics to build label-free Cd quantitative models. The silver nanoparticles synthesized by SA had good dispersion and enhancement factor (3.48 × 105).

Soil health plays a vital role to sustain plants, animals, and humans (Lehmann et al., 2020).

In the present study, lead, zinc and copper concentrations in the feathers of Common kestrel (Falco tinnunculus), Eurasian magpie (Pica pica), Common buzzard (Buteo buteo), Crested lark (Galerida cristata), Eurasian hoopoe (Upupa epops), Little owl (Athene noctua), Long-eared owl (Asio otus), Eurasian eagle-owl (Bubo bubo) and Long-legged buzzard (Buteo rufinus) from Sabzevar and Neghab, Khorasan Razavi of Iran w

Detecting and monitoring the usage of antibiotics is a critical aspect of efforts to combat antimicrobial resistance. Antibiotic residue testing with existing LC-MS/MS methods is limited in detection range. Current methods also lack the capacity to detect multiple antibiotic residues in different samples simultaneously. In this study, we demonstrate a methodology that permits simultaneous extraction and detection of antibiotic residues in animal and environmental samples.

Lead (Pb) is an environmental neurotoxin that can lead to toxicity. It has shown that tissues can be exposed to oxidative stress in lead poisoning. Since silymarin is a natural agent with antioxidant effects, this study aimed to investigate the antioxidant and chelation effects of silibinin and nano-silibinin on the oxidative stress status in lead-poisoned rats. Sixty male Wistar rats randomly divided into ten groups (n=6).

The objective of this study was to evaluate the physiological characteristics and rhizofiltration potential of Talinum paniculatum cuttings subjected to lead (Pb) and manganese (Mn) excess. The cuttings excised from T. paniculatum were transferred to a nutrient solution, to which different concentrations of Pb (0, 10, 50, 100, and 200 mg L−1) and Mn (0, 10, 50, 100, and 150 mg L−1) were added.

Abstract Heavy metals (HMs), among the components of air pollution that is one of the utmost critical concerns our world has faced, are one of the biggest threats to living organisms. The plants, as a biomonitor, offer the most effective solution in tracking the change of HM concentration on earth and taking them under control.

Background and aims Chelates like ethylenediaminetetraacetic acid (EDTA) have frequently been applied for facilitating lead (Pb) phytoextraction and cleaning contaminated soils but without detailed report regarding the internal mechanisms happening in plants in response to EDTA addition.

Journal of the Science of Food and Agriculture, EarlyView. BACKGROUND Cadmium is a non-biodegradable heavy metal with a long biological half-life.

Background Non-Hispanic Asians (NHA) in USA have been reported with higher arsenic (As), lead (Pb), cadmium (Cd), mercury (Hg) and their specific species levels, comparing with non-NHA.

Aim:To present the content, data quality, and research potential of the West Jutland Tele-Electrocardiogram Registry (WEJU-tECG).Methods:Danish patients reporting symptoms indicating heart disease in the prehospital setting are subjected to a 12-lead tele-electrocardiogram (ECG) in the ambulance, which is digitally sent to a local tele-centre.

Oxytetracycline is an antibiotic authorized for use in aquaculture and is often detected in seafood products, especially shrimp. Previous studies investigating the fate of oxytetracycline in shrimp tissues after cooking were limited to quantification of parent compound residues, and did not describe any potential transformation products formed. Hence, the main objective of this study was to apply a non-target analysis workflow to study the fate of oxytetracycline in shrimp muscle.

This multi-institutional study assessed the efficacy of Enterococcus faecium NRRL B-2354 as a non-pathogenic Salmonella surrogate for thermal processing of nonfat dry milk powder, peanut butter, almond meal, wheat flour, ground black pepper, and date paste. Each product was analyzed by two laboratories (five independent laboratories total), with the lead laboratory inoculating (E. faecium or a five-strain Salmonella enterica cocktail of S.

Abstract Insects and fungal pathogens pose constant problems to public health and agriculture, especially in resource-limited parts of the world; and the use of chemical pesticides continues to be the main methods for the control of these organisms. Photorhabdus spp.

Since its emergence in the beginning of the 90’s, multidrug-resistant (MDR) Salmonella enterica subsp. enterica serovar Kentucky has become a significant public health problem, especially in East Africa. This study aimed to investigate the antimicrobial resistance profile and the genotypic relatedness of Salmonella Kentucky isolated from animal sources in Ethiopia and Kenya (n=19).

In this study, topsoil and soil profiles were collected from typical karst areas in central Guizhou to investigate the accumulation and bioavailability of As in cultivated soils. The parent material of the investigated soil is carbonate rock, but there is strong heterogeneity in the As concentrations of soils developed in the Permian and Triassic, with average concentrations of 18.31 and 40.35 mg/kg, respectively.

Human health is threatened by antibiotic-resistant bacteria and their related infections, which cause thousands of human deaths every year worldwide. Surface waters are vulnerable to human activities and natural processes that facilitate the emergence and spread of antibiotic-resistant bacteria in the environment. This study evaluated the pathways and drivers of antimicrobial resistance (AR) in surface waters.

Arsenobetaine (AsB) is a primary arsenic (As) compound found in marine organisms. However, in mammals, the metabolic mechanism of AsB remains indistinct.

Sumoylation is a posttranslational modification (PTM) in which SUMO (small ubiquitin-like modifier) is covalently conjugated to protein substrates via a range of enzymes. SUMO E3 ligase SIZ1 is involved in mediating several essential or nonessential element-responsive SUMO conjugations in Arabidopsis. However, whether SIZ1 is involved in the cadmium (Cd) response remains to be identified. In this study, we found that SIZ1 positively regulates plant Cd tolerance.

Lead (Pb) is a non-essential toxic heavy metal that can accumulate in the environment over time and enter the body through the respiratory tract, skin, and gastrointestinal tract.
