Larvicidal Activity of Phytochemicals From Handroanthus impetiginosus Seeds Against Culex quinquefasciatus. [PDF]

Chem Biodivers
The hexane extract was obtained from the seeds of H. impetiginosus, from which fatty acids and FAMEs were obtained. The three samples were tested on C. quinquefasciatus larvae, promoting mortality with moderate LC50 values. The hexane extract was analyzed by gas chromatographymass spectrometry (GC‐MS), and the most abundant compounds were ethyl oleate (

Intraspecific Trait Variation in Tree Species Responds to Environmental Heterogeneity at Range-Wide but Not Local Scales. [PDF]

Ecol Evol
Here we explore the relationship between ITV, spatial and temporal environmental heterogeneity, and the breadth of species' environmental distributions for 33 tree species across eight sites across marked environmental gradients in Puerto Rico. Species with greater across‐site ITV in wood density and LMA occurred over broader ranges of potential ...

Silk Fibroin-Stabilized Lapachol Microemulsion Enhances Antiglioma Activity In Vitro. [PDF]

Chem Biodivers
Silk fibroin‐stablized lapachol microformulation antiglioma activity. ABSTRACT Gliomas are the most prevalent of the brain tumors, and are associated with high mortality and limited therapeutic options. This study introduces, for the first time, a silk fibroin (SF)‐based microemulsion as a nanocarrier for lapachol (LP).
