Occurrence and Human Health Implications of Legacy Organochlorine Pesticides and Their Metabolites in Fruits and Vegetables of Bangladesh

open access: yesFood Safety and Health, EarlyView.
Multiple OCP isomers and/or metabolites along with their parent compounds were detected in commonly consumed fruits and vegetables of Bangladesh, possibly attributed to both recently and historically applied OCPs. However, all the detected values were below 0.01 mg/kg, indicating no potential human health risks through dietary intake. ABSTRACT Globally,

Isomerization of α‐Pinene Oxide to Trans‐Pinocarveol

open access: yesHelvetica Chimica Acta, EarlyView.
An operationally simple protocol for the selective isomerization of α‐pinene oxide (APO) to trans‐pinocarveol (TPC) is disclosed, which leverages inexpensive pyridinium‐halide organocatalysts to mitigate competing 1,2‐alkyl shifts. The scalability of this methodology is demonstrated on a decagram scale and catalyst‐recycling is validated through the ...

Evaluating the Endocrine‐Disrupting and Oxidative Stress Potential of a 50‐Component Human‐Relevant Complex Chemical Mixture Using In Vitro Tests

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Humans are chronically exposed to mixtures of environmental contaminants. Exposure to endocrine‐disrupting chemicals (EDCs) contributes to increased health impairment observed globally. This study aimed to evaluate the endocrine‐disruptive and oxidative stress potential of a human‐relevant, complex chemical mixture in vitro.

Developmental exposure to low doses of dichlorodiphenyltrichloroethane disrupts functional and morphologic maturation of the spleen in prepubertal rats

open access: yesRussian Open Medical Journal
Dichlorodiphenyltrichloroethane (DDT) is a versatile persistent pollutant with endocrine disrupting properties and an alleged immune modulator. Objective — to evaluate the parameters of functional and morphological maturation of the spleen in prepubertal

Metabolic and target-site mechanisms combine to confer strong DDT resistance in Anopheles gambiae.

open access: yesPLoS ONE, 2014
The development of resistance to insecticides has become a classic exemplar of evolution occurring within human time scales. In this study we demonstrate how resistance to DDT in the major African malaria vector Anopheles gambiae is a result of both ...

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Selectively Cleavable Silicone Elastomers Based on Acetal Cross‐Linkers: Synthesis, Properties, and Study of Chemical Degradation

open access: yesJournal of Polymer Science, EarlyView.
A novel silicone elastomer based on selectively cleavable acetal cross‐linkers incorporated by hydrosilylation was developed. Different acetal cross‐linkers were synthesized and introduced into a silicone formulation of vinyl‐terminated PDMS and tetrakis(dimethylsiloxy)silane using Karstedt's catalyst.

CASP16 Protein Monomer Structure Prediction Assessment

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The assessment of monomer targets in the Critical Assessment of Structure Prediction Round 16 (CASP16) underscores that the problem of single‐domain protein fold prediction is nearly solved—no target folds were incorrectly predicted across all Evaluation Units.
