Estudi experimental del tractament de la meningitis pneumocòcica produïda per soques resistents a cefalosporines de tercera generació. Virulència, eficàcia i resposta inflamatòria [PDF]
, 2006 [cat] La meningitis pneumocòcica és una malaltia associada a una elevada mortalitat (20-40) i a l'aparició de seqüeles neurològiques en un 30% dels pacients, nens i adults, que sobreviuen.

Advanced Healthcare Materials, EarlyView.We describe a microfluidic tumor‐stroma co‐culture model, engineered to resist collagen‐hydrogel contraction driven by fibroblast activity. Surface silanization with APTES covalently anchors the matrix to the chip, while Genipin crosslinking progressively increases stiffness and elasticity without harming cells. This supports >10 days of co‐culture and

Mechanisms of penicillin-resistance in streptococcus uberis
, 2009 Background: S. uberis is a member of the streptococcal pyogenic group and a causative agent of bovine mastitis, which are frequently treated with penicillin. Despite the report of decreased susceptibility in certain environmental isolates, the ability of

Advanced Healthcare Materials, EarlyView.A miniaturized drug sensitivity and resistance testing (DSRT) workflow based on the Droplet Microarray (DMA) platform enables functional drug testing using minimal patient‐derived tumor material. By screening nanoliter‐scale droplets containing as few as 300 cells, this approach generates reproducible and tumor‐specific drug response profiles ...

Engineering of Glioblastoma‐Derived Biomimetic Vesicles and Their Structural and Molecular Features
Advanced Healthcare Materials, EarlyView.ABSTRACT Biomimetic nanosystems and vesicles have arisen as a novel approach to design vesicular transport systems with diverse therapeutic potential. The ‘biomimetic’ strategy involves the integration of cell membrane components into lipid bilayers, conferring them with biological properties originating from the cell of origin. Until now, most studies

Advanced Healthcare Materials, EarlyView.This study presents a bioengineered assembloid (ASM) system combining glioblastoma (GBM) cells in oxidized alginate (OA) microgels with dorsal organoids (DOs). This model simulates brain tumor‐host interactions, revealing enhanced GBM invasion, altered gene expression, and aggressive infiltration patterns, demonstrating ASM as a valuable platform for ...

Penicillin-resistant pneumococci in Sweden : epidemiology and public health response
, 2005 Since 1996, all identified cases of pneumococci with a MIC for penicillin G > 0.5 mg/L (penicillin resistant pneumococci: PRP) have been registered according to the Swedish Communicable Disease Act.

Design and Synthesis of Peptide‐Polyester Conjugates for Cell‐Mediated Scaffold Degradation
Advanced Healthcare Materials, EarlyView.This work describes polycaprolactone (PCL)‐based biomaterials engineered to degrade in response to cell‐secreted proteases. A fast‐degrading peptide (Fast) sequence is integrated into a PCL conjugate backbone to produce a biomaterial that is selectively degraded by multiple cell types compared to its scrambled control (ScrFast).
