Identification of Antioxidant, Antimicrobial, and Cytotoxic Compounds From Hymenocardia acida Tul. Using Ultra‐High‐Performance Liquid Chromatography‐Quadrupole Exactive‐Orbitrap‐Mass Spectrometry and Molecular Networking Approach

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Hymenocardia acida Tul. is a medicinal plant used in Angola to treat microbial diseases. It is a well‐known plant among local populations; however, few studies have focused on the assessment of phytochemicals associated with their biological activities.

Biochemical Responses of Anopheles spp. Larvae to a Novel Brazilian BR101 Bacillus thuringiensis var. israelensis Formulation: Oxidative Stress, Detoxification Enzymes, and Safety for Nontarget Notonectidae and Gerridae Aquatic Insects

open access: yesChemistry &Biodiversity, EarlyView.
Bti BR101 exhibits strong larvicidal activity against Anopheles larvae spp., with dose‐dependent mortality and LC50 of 3.13 µg/mL. Bti increases ROS, lipid and protein oxidation, and activates antioxidant enzymes (SOD, CAT, GPx) and detoxification pathways (MFO and esterases), indicating moderate oxidative stress.

Mini‐Hairpin DNA: Extraordinarily Stable Structure and Its Applications

open access: yesChemistry – A European Journal, EarlyView.
Mini‐hairpin DNA fragments containing GCGAAGC and GCGAAAGC form exceptionally stable hairpin‐like structures, with only two G−C pairs and one sheared G−A pair, remaining undenatured in 7 M urea and resisting nuclease digestion. These mini‐hairpin sequences frequently appear in replication and transcription origins, influence DNA sequencing fidelity ...

Mid‐Infrared Spectroscopy and Machine Learning for Chlorogenic Acid Quantification in Coffee

open access: yesChemie Ingenieur Technik, EarlyView.
Chlorogenic acid (CGA) concentration in coffee was predicted using mid‐infrared (MIR) spectroscopy and a machine learning approach. Forty‐four roasting stages (140–220 °C) plus a green coffee control were analyzed. A multilayer perceptron regressor, trained on preprocessed MIR data, outperformed traditional peak analysis, enabling accurate and ...

Actin Isovariant ACT2‐Mediated Cellular Auxin Homeostasis Regulates Lateral Root Organogenesis in Arabidopsis thaliana

open access: yesCytoskeleton, EarlyView.
ABSTRACT Lateral root (LR) organogenesis is regulated by cellular flux of auxin within pericycle cells, which depends on the membrane distribution and polar localization of auxin carrier proteins. The correct distribution of auxin carrier proteins relies on the intracellular trafficking of these proteins aided by filamentous actin as a track.
