Bayesian optimized color filter: A fast method for segmentation of plant phenotypes from 3D point cloud images

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Multispectral three‐dimensional (3D) imaging offers substantial potential for plant phenotyping, yet manual segmentation of plant organs remains a bottleneck in breeding programs. We developed a color‐based filtering workflow for faba bean (Vicia faba L.) point clouds that optimizes lower and upper thresholds of spectral indices and broadband ...

Integrated Multispectroscopic Identification of Organophosphorus and Triazine Pesticide Mixtures via DFT–Spectroscopy‐Integrated Identification Method (D‐SIIM)

open access: yesAnalysis &Sensing, Volume 6, Issue 6, November 2026.
Identifying unknown chemicals in mixtures is limited by the reference libraries available. D‐SIIM instead cross‐validates experimental IR, Raman, and NMR spectra against DFT predictions, resolving all components of pesticide mixtures containing up to four multiring organophosphorus and triazine compounds including one for which GC–MS screening proved ...

Activity and Residual Effect of Two Formulations of Lambdacyhalothrin Sprayed on Palm Leaves to Rhodnius prolixus

open access: yesMemorias do Instituto Oswaldo Cruz, 2002
The insecticidal activity and residual effect of two formulations of lambdacyhalothrin were evaluated with Rhodnius prolixus;laboratory and field tests were conducted in the State of Chiapas, Mexico. The results indicate that the lethal concentrations of

Pediatric Developmental Safety Assessment and New Approach Methodologies: US FDA/Triangle CERSI Workshop Report

open access: yesClinical Pharmacology &Therapeutics, Volume 120, Issue 5, Page 1240-1249, November 2026.
Pediatric developmental safety assessment presents distinct challenges in drug development. Children undergo dynamic changes in organ systems and drug disposition pathways during development, and drug‐related effects may be delayed or manifested differently than in adults.

Health Biomarkers of Pesticide Exposure in Rural Populations of Santa Fe, Argentina: Oxidative Stress and Genotoxicity

open access: yesJournal of Applied Toxicology, Volume 46, Issue 11, Page 3804-3813, November 2026.
ABSTRACT The present study aimed to quantify pesticide residues in environmental matrices and plasma and to evaluate their potential effects on oxidative stress and DNA damage in rural populations of Santa Fe province. Soil and rainwater samples were collected, and biological samples and semistructured surveys were obtained from volunteers in three ...

Assessment of the inhibitory effects of pyrethroids against human carboxylesterases

open access: yes, 2017
Pyrethroids are broad-spectrum insecticides that widely used in many countries, while humans may be exposed to these toxins by drinking or eating pesticide-contaminated foods.

RNA degradomics and proteomics reveal the mechanism of dsProsβ1‐mediated proteasome targeting in Psylliodes chrysocephala

open access: yesPest Management Science, Volume 82, Issue 11, Page 10604-10614, November 2026.
RNA degradomics revealed dsProsβ1‐derived siRNA‐mediated mRNA cleavage events, mainly at uracil‐guanine and adenine‐adenine pairs. Proteasome inhibition via dsProsβ1 increased mitochondrial and cytoskeletal proteins while reducing translation‐related and mRNA‐binding proteins.

Combined effects of canola plant density and insecticide management strategies on flea beetle abundance, canola defoliation, and yield across the Canadian prairies

open access: yesPest Management Science, Volume 82, Issue 11, Page 10648-10657, November 2026.
Increasing canola plant density reduced flea beetle abundance per plant and increased yield, independent of region or insecticide use, highlighting its potential as a component of integrated pest management. Abstract The crucifer flea beetle, Phyllotreta cruciferae (Goeze), and the striped flea beetle, Phyllotreta striolata (Fabricius) (Coleoptera ...

Synthetic pyrethroids [PDF]

open access: yes, 2012
Piretroidi su sintetski dobiveni spojevi slične strukture i djelovanja kao prirodni insekticid piretrin. Prema mehanizmu djelovanja živčani su otrovi koji djeluju na prenošenje živčanih impulsa na način da pobuđuju reakcije crpki iona kalija i natrija ...
