Osteological correlates of the respiratory and vascular systems in the neural canals of Mesozoic ornithurines Ichthyornis and Janavis

open access: yesThe Anatomical Record, EarlyView.
Abstract In birds, the neural canal houses a variety of anatomical structures including the spinal cord, meninges, spinal vasculature, and respiratory diverticula. Among these, paramedullary diverticula and the extradural dorsal spinal vein may leave behind osteological correlates in the form of pneumatic foramina and fossae, and a bilobed geometry of ...

Effective acetalization of furfural catalyzed by Fe‐ and Co‐oxalates: impact of alcohols structure on products composition

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Fe‐, Co‐, and FeCo‐oxalates supported on silica gel (5 wt% metal load) were synthesized, characterized, and tested for the first time in solvent‐free furfural (FF) acetalization with C1–C8 alcohols at 70–170 °C under both conventional and microwave (MW)‐assisted conditions. The interaction of FF with linear C1–C4 alcohols yielded pincer‐shaped

An automated microfluidic biosensor with bispecific rabbit monoclonal antibody and nanozyme‐bioenzyme composite for dual antibiotic detection

open access: yesBMEMat, EarlyView.
This study introduces an automated microfluidic biosensor for simultaneous detection of florfenicol and thiamphenicol in environmental water. By integrating a phage‐screened bispecific rabbit monoclonal antibody with a nanozyme‐bioenzyme composite, the system achieves sensitive dual‐antibiotic detection. Coupled with smartphone‐based sensing, it offers
