Dicarboxymethyl Cellulose‐Based Mixed‐Matrix Membrane Adsorbers: Preparation, Characterization, and Protein Retention Performance

open access: yesJournal of Applied Polymer Science, EarlyView.
Dicarboxymethyl cellulose is incorporated, for the first time, into a polyethersulfone membrane. The functional membranes are prepared using dimethyl isosorbide through combined non‐solvent and vapor‐induced phase separation. The resulting membranes exhibit porous structures and protein‐retention potential, highlighting the potential of this cellulose ...

Much more than their fangs: Macroscopic anatomy of the brain of Bothrops moojeni Hoge 1966 (Squamata, Serpentes, Viperidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract Neuroanatomical research has progressed considerably in several vertebrate lineages, yet studies of reptilian brain morphology remain markedly underdeveloped. Here we provide the first description of macroscopic brain anatomy and its ontogeny in the viperid Bothrops moojeni, based on a sample of seven individuals.

Hepatic morphology and serum biochemical profile according to dry and rainy seasons in Pygocentrus nattereri (Characiformes: Serrasalmidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract This study investigated the physiological and morphological adaptations of the liver of the carnivorous fish Pygocentrus nattereri (piranha) in response to seasonal variations (dry and rainy seasons) in the Brazilian Pantanal. The objective was to describe how the liver, a central organ in metabolic regulation, responds to environmental ...
