Here, we prepared a series of novel osthole-type ester derivatives modified in the lactone ring of osthole, which is isolated from Cnidium monnieri. The positions of H-3 and H-4 of the representative compound 4z were determined by a 1H–1H COSY spectrum. By opening the lactone ring of osthole, the double bonds at the C-3 and C-4 positions of diol 3 and esters 4a–4z, 4a′, and 4b′ were still retained as a Z configuration.

A novel sensitive method for simultaneous determination of 19 antibiotics and 19 anthelmintics in edible fungi using QuEChERS-UHPLC-MS/MS method was established. For every 10.0 g sample, 20 mL of acetonitrile with 2% acetic acid and 1.2 g sodium acetate were used for extraction, followed by 6.0 g anhydrous MgSO4 for dehydration, and 50 mg anhydrous MgSO4+10 mg PSA for purification.

Journal of Separation Science, Accepted Article. Endocrine disrupting chemicals are chemicals that interfere with any aspect of the endocrine system. Several natural and synthetic chemicals including pesticides have been identified as endocrine disruptors, which potentially inhibit the reproductive activity of the hormonal system. The pervasive occurrence with trace level concentrations and extensive variety are the reported characteristics of these chemicals.

Exposure through arsenic-contaminated air and food caused by the burning of coal is a major environmental public health concern in Guizhou Province of China. Previous studies have shown that immunological dysfunction is involved in the pathogenesis and carcinogenesis of arsenic; however, knowledge regarding effective prevention measures have not been fully examined.

A multiresidue method was developed and validated for the simultaneous determination of eight synthetic pyrethroids and hexaconazole fungicide residues in curry leaves. The method involves extraction of leaf sample with ethyl acetate, purified by dispersive SPE with primary secondary amine and graphitized carbon black.

The worldwide expansion of chikungunya virus (CHIKV) into tropical and subtropical areas in the last 15 years has posed a currently unmet need for vaccines and therapeutics. The E2-E1 envelope glycoprotein complex binds receptors on the host cell and promotes membrane fusion during CHIKV entry, thus constituting an attractive target for the development of antiviral drugs.

Concentrations of polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) were measured in 23 seafood species widely consumed by the Korean population in the periods of 2005–2007, 2010–2011, and 2015–2017. The Σ82PCB (sum of 82 PCB congeners) and Σ19PBDE (sum of 19 PBDE congeners) concentrations in the seafood samples of 2015–2017 were 0.06–6.69 ng/g wet weight and 0.01–1.60 ng/g wet weight, respectively.

Methylmercury (MeHg) is a toxic and bioaccumulative organo-metallic compound that is naturally produced in many ecosystems. Organisms that occupy the lower trophic positions in food webs may be key factors in the assessment of MeHg biomagnification between ecosystems. Here we present a review of the peer-reviewed literature examining MeHg bioaccumulation in freshwater invertebrates, focused principally on insects.

Nanoparticles with high reactivity can be applied as amendments to remediate soil metal contaminations by immobilizing toxic elements. Nano-oxides of Fe have been studied but Al and Ti nano-oxides have not been tested for their remediation capacity of toxic metals.

The growth of edible crops on land that is highly polluted with potentially toxic elements is prohibited in many developed countries, but the growth of fiber or energy crops may be permitted. Here, we have evaluated metal immobilization in a maize field polluted with cadmium (Cd) and lead (Pb) to determine the thresholds of soil CaCl2-extractable Cd and Pb and to assess management options designed to maximize food safety.

A wide range solubility of water is the main cause of its contamination by variety of inorganic/organic pollutants and hence needs decontamination using various porous materials. It is needed and still is a challenging task of time to develop porous materials like metal organic frameworks for the said purpose.

Background Approximately one-third of cases of cardiovascular implantable electronic device (CIED) infection present as CIED lead infection. The precise transesophageal echocardiographic (TEE) definition and characterization of “vegetation” associated with CIED lead infection remain unclear. Methods We identified a sample of 25 consecutive cases of CIED lead infection managed at our institution between January 2010 and December 2017.

Since the turn of the 21st century, during which White mortality has been rising, there has been a sharp increase in only 3 causes of death: drug use, alcohol use, and suicide. Because all 3 of these causes conjure notions of anguish and hopelessness, they have been conceptualized as a collective “deaths of despair” phenomenon. Simon and Masters (Am J Epidemiol. 2021;190(6)1169-1171) challenge this conceptualization by asking whether these 3 causes are empirically associated with each other.
