Systemic Administration of Calea pinnatifida Inhibits Inflammation Induced by Carrageenan in a Murine Model of Pulmonary Neutrophilia

open access: yesMediators of Inflammation, Volume 2020, Issue 1, 2020., 2020
Objective. The aim of this study was to investigate the anti‐inflammatory effects of the crude extract (CE), derived fraction, and isolated compounds from Calea pinnatifida leaves in a mouse model of pulmonary neutrophilia. Methods. The CE and derived fractions, hexane, ethyl acetate, and methanol, were obtained from C. pinnatifida leaves.

Ordered Nanostructural Engineering of Cathode Catalyst Layer With High Mass Transport Efficiency for High‐Performance Ultra‐Low Pt Loading Proton Exchange Membrane Fuel Cells

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
An ordered cathode catalyst layer with efficient mass transport capability was developed based on the ALD of Pt onto VACNTs for high‐performance ultra‐low Pt loading PEMFC. The order‐structured cathode catalyst layer (CCL) has been considered the most promising solution to construct low‐cost proton exchange membrane fuel cells (PEMFCs) with an ultra ...

Immunoaffinity‐Based Protocol to Enrich Nervous System Cell‐, Lung Alveolar Cell‐, and Hepatocyte‐Derived Extracellular Vesicles From Human Plasma

open access: yesJournal of Extracellular Biology, Volume 5, Issue 7, July 2026.
ABSTRACT By preserving molecular information inherited from the source cell, extracellular vesicles (EVs) can serve as biomarkers for tissue health or disease, paving the way for liquid biopsy applications. The enrichment of tissue‐specific EVs (TS‐EVs) from human biofluids can be challenging due to technical and methodological limitations.
