Allelopathy as a Strategy for Biological Invasion: Calotropis procera and Its Impact on Plant Succession

Chemistry &Biodiversity, EarlyView.
Stages of the study on the allelopathic potential of Calotropis procera (Aiton) W. T. Aiton. The image shows the collection of plant material, the decomposition of organic matter, the identification of bioactive compounds, and the effects on the germination of Handroanthus impetiginosus (Mart. ex DC.) Mattos.

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

Chemistry &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.

Evaluation of the Therapeutic Potential of Bioactive Materials Based on a Complex of Oxidovanadium(IV) and Exopolysaccharide Levan in a Model of Insulin Resistance in Mice

ChemMedChem, EarlyView.
A low‐toxicity bioactive composition of oxidovanadium(IV) and exopolysaccharide levan is synthesized, characterized, and shown to reduce hyperglycemia, hypertriglyceridemia, and TyG index in a mice model of dexamethasone‐induced insulin resistance. Bioactive compositions containing vanadium complexes have been a viable strategy for constructing more ...

Myomaker and Myomixer are required for craniofacial myoblast fusion in zebrafish

Developmental Dynamics, EarlyView.
Abstract Background Craniofacial and trunk skeletal muscles are derived from different progenitor populations during development. Trunk skeletal muscles contain mostly multinucleated myofibers that are formed through myoblast fusion. However, myoblast fusion in craniofacial muscles and its molecular regulation are not well understood.

Photoperiodism as a Modifier of Effect of Extremely Low-Frequency Electromagnetic Field on Morphological Properties of Pineal Gland

Biomolecules & Biomedicine, 2006
The aim of our study was to determine, using histological and stereological methods, whether photoperiodism has any impact on the effects that chronic (three-month long) exposure to LF-EMF (50Hz) has on morphological characteristics on rat's pineal ...

Temperature variability homogenized thermal responses in an ectotherm community along a European longitudinal gradient

Ecography, EarlyView.
Climate change, through rising temperatures, greater variability, and more frequent extremes, is reshaping insect phenology and thermal niches, with profound effects for pest outbreaks. Predicting these impacts requires a clear understanding of species and communities' responses across geographic gradients.
