Microfluidic 3D platform to evaluate endothelial progenitor cell recruitment by bioactive materials
Most of the conventional in vitro models to test biomaterial-driven vascularization are too simplistic to recapitulate the complex interactions taking place in the actual cell microenvironment, which results in a poor ...
Chemotactic sprouting of Endothelial Cells through an Extracellular Matrix
Sprouting angiogenesis is a core biological process critical to vascular development. Its accurate simulation, relevant to multiple facets of human health, is of broad, interdisciplinary appeal. This study presents an ...
Nanostructured materials for photodynamic therapy: synthesis, characterization and in vitro activity
Three nanostructured vehicles are proposed as potential carriers for photosensitizers to be used in photodynamic therapy: spherical nanoparticles, hexahedral microparticles and cylindrical magnetic nanorods. A comparative ...
Silver nanoparticles-composing alginate/gelatine hydrogel improves wound healing in vivo
Polymer hydrogels have been suggested as dressing materials for the treatment of cutaneous wounds and tissue revitalization. In this work, we report the development of a hydrogel composed of natural polymers (sodium alginate ...
Stochastic modulation evidences a transitory EGF-Ras-ERK MAPK activity induced by PRMT5
The extracellular signal-regulated kinase (ERK) mitogen-activated protein kinase (MAPK) pathway involves a three-step cascade of kinases that transduce signals and promote processes such as cell growth, development, and ...
Perspectives of the Application of Non-Steroidal Anti-Inflammatory Drugs in Cancer Therapy: Attempts to Overcome Their Unfavorable Side Effects
Non-steroidal anti-inflammatory drugs (NSAIDs) express anti-tumoral activity mainly by blocking cyclooxygenase-2 involved in the synthesis of prostaglandins. Therefore, in the last few decades, many have attempted to ...
Amyloids in Solid-State Nuclear Magnetic Resonance: Potential causes of the usually low resolution
Amyloids are non-crystalline and insoluble, which imply that the classical structural biology tools, ie, X-ray crystallography and solution nuclear magnetic resonance (NMR), are not suitable for their analysis. In the last ...
Electrodeposition of CoNi alloys in a biocompatible DES and its suitability for activating the formation of sulfate radicals
Building a sustainable future requires new, accessible, economic, and ecological methods of preparing nanostructured materials used in biomedical and environmental applications. In this work, a detailed study on the ...
Low-cost fabrication of printed electronics devices through continuous wave laser-induced forward transfer
Laser induced forward transfer (LIFT) is a direct-writing technique that allows printing inks from a liquid film in a similar way to inkjet printing but with fewer limitations concerning ink viscosity and loading particle ...
Luminescent Pt-II and Pt-IV Platinacycles with Anticancer Activity Against Multiplatinum-Resistant Metastatic CRC and CRPC Cell Models
Platinum-based chemotherapy persists to be the only effective therapeutic option against a wide variety of tumours. Nevertheless, the acquisition of platinum resistance is utterly common, ultimately cornering conventional ...
Optimization, biopharmaceutical profile and therapeutic efficacy of pioglitazone-loaded PLGA-PEG nanospheres as a novel strategy for ocular inflammatory disorders.
PURPOSE: The main goal of this study was to encapsulate Pioglitazone (PGZ), in biodegradable polymeric nanoparticles as a new strategy for the treatment of ocular inflammatory processes. METHODS: To improve their ...
Kinetico-mechanistic insights into the photodynamic process of AuI complexes with the CNC6H4NNC6H5 (iso-Ph) azobenzene ligand
A family of neutral isocyanide monoazo AuI complexes [AuCl(iso-Ph)], [Au(C6F5)(iso-Ph)] and [Au(C[triple bond, length as m-dash]Cpy)(iso-Ph)] (iso-Ph being CN–C6H4–N[double bond, length as m-dash]N–Ph) and a closely related ...
YAT2150: Overcoming limitations of traditional amyloid dyes in aggregation studies
Amyloid fibrils, which are aggregates of misfolded proteins characterized by β-sheet-rich structures, are implicated in several neurodegenerative and systemic pathologies, including Alzheimer’s and Parkinson’s diseases and ...
Injection locking in an optomechanical coherent phonon source
Spontaneous locking of the phase of a coherent phonon source to an external reference is demonstrated in a deeply sideband-unresolved optomechanical system. The high-amplitude mechanical oscillations are driven by the ...
Differentiation of Epoxide Enantiomers in the Confined Spaces of an Homochiral Cu(II) MOF by Kinetic Resolution
TAMOF-1, a homochiral metal-organic framework (MOF) constructed from an amino acid derivative and Cu(II), was investigated as a heterogeneous catalyst in kinetic resolutions involving the ring opening of styrene oxide with ...
Néel vector waves in antiferromagnetic CuMnAs excited by surface acoustic waves
Magnetoelastic effects in antiferromagnetic CuMnAs are investigated by applying dynamic strain in the 0.01% range through surface acoustic waves in the GaAs substrate. The magnetic state of the CuMnAs/GaAs is characterized ...
Transparent and conductive silver nanowires networks printed by laser-induced forward transfer
Networks of silver nanowires (Ag-NWs) can be electrically conductive and optically transparent at the same time. Thus, Ag-NWs are promising candidates for substituting transparent and conductive oxides like indium-tin-oxide. ...
