Monitoring the insertion of Pt into Cu2−xSe nanocrystals: a combined structural and chemical approach for the analysis of new ternary phases
The tuning of the chemical composition in nanostructures is a key aspect to control for the preparation of new multifunctional and highly performing materials. The modification of Cu2−xSe nanocrystals with Pt could provide ...
Feasible and pure P2O5-CaO nanoglasses: An in-depth NMR study of synthesis for the modulation of the bioactive ion release
Vascularization is a multifactorial and spatiotemporally regulated process, essential for cell and tissue survival. Vascular alterations have repercussions on the development and progression of diseases such as cancer, ...
PPARγ agonist-loaded PLGA-PEG nanocarriers as a potencial treatment for Alzheimer's disease: in vitro and in vivo studies.
Objective: The first aim of this study was to develop a nanocarrier that could transport the peroxisome proliferator-activated receptor agonist, pioglitazone (PGZ) across brain endothelium and examine the mechanism of ...
Cytotoxicity of osmium(ii) and cycloosmated half-sandwich complexes from 1-pyrenyl-containing phosphane ligands
Five metal-arene complexes of formula [MX2(η6-p-cymene)(diR(1-pyrenyl)phosphane)] (M = Os or Ru, X = Cl or I, R = isopropyl or phenyl) and symbolized as MRX2 were synthesized and fully characterized, namely OsiPrCl2, ...
Aproximacions a la perspectiva de la persona en tractament de manteniment amb metadona: Reflexions a propòsit de 10 anys de recerca
Els tractaments de manteniment amb metadona (TMM) són un autèntic tractament psicofarmacològic de la dependència d'heroïna i, a la vegada, un element indispensable de les polítiques i les intervencions de reducció de danys. ...
Synergistic antipseudomonal effects of synthetic peptide AMP38 and carbapenems
The aim was to explore the antimicrobial activity of a synthetic peptide (AMP38) and its synergy with imipenem against imipenem-resistant Pseudomonas aeruginosa. The main mechanism of imipenem resistance is the loss or ...
The Involvement of Peripheral and Brain Insulin Resistance in Late Onset Alzheimer's Dementia
Nowadays, Alzheimer's disease (AD) is a severe sociological and clinical problem. Since it was first described, there has been a constant increase in its incidence and, for now, there are no effective treatments since ...
Unraveling the Formation of Ternary AgCuSe Crystalline Nanophases and Their Potential as Antibacterial Agents
AgCuSe nanoparticles could contribute to the growth of strongly light-absorbing thin films and solids with fast ion mobility, among other potential properties. Nevertheless, few methods have been developed so far for the ...
Immunoliposome-mediated drug delivery to Plasmodium-infected and non-infected red blood cells as a dual therapeutic/prophylactic antimalarial stragegy
One of the most important factors behind resistance evolution in malaria is the failure to deliver sufficiently high amounts of drugs to early stages of Plasmodium-infected red blood cells (pRBCs). Despite having been ...
Multifunctional Serine Protease Inhibitor-Coated Water-Soluble Gold Nanoparticles as a Novel Targeted Approach for the Treatment of Inflammatory Skin Diseases
The overexpression and increased activity of the serine protease Kallikrein 5 (KLK5) is characteristic of inflammatory skin diseases such as Rosacea. The use of inhibitors of this enzyme¿such as 4-(2-aminoethyl)benzenesulfonyl ...
A versatile luminescent probe for sensing and monitoring amyloid proteins
A modified lysine residue containing an environment-sensitive moiety was prepared through a straightforward synthesis, and its fluorescent properties were examined. The new fluorescent sensor, DMN-BocK, can monitor amyloid ...
A genomics approach identifies selective effects of trans-resveratrol in cerebral cortex neuron and glia gene expression
The mode of action of trans-resveratrol, a promising lead compound for the development of neuroprotective drugs, is unknown. Data from a functional genomics study were retrieved with the aim to find differentially expressed ...
Study of the magnetoelastic effect in nickel and cobalt thin films at GHz range using x-ray microscopy
We use surface acoustic waves of 1 and 3 GHz in hybrid piezoelectric-magnetic systems with either nickel or cobalt as a magnetic layer to generate magnetoacoustic waves and directly image them using stroboscopic x-ray ...
Photoluminescence from carbon structures grown by inductively coupled plasma chemical vapor deposition
Carbon micro/nanostructures were grown by inductively coupled plasma chemical vapor deposition (ICP-CVD) at low pressure into a tubular reactor under pure methane and using substrates of SAE 304 stainless steel. The samples ...
Ignition of CO2 methanation using DBD-plasma catalysis in an adiabatic reactor
In this work, a novel strategy of the use of dielectric barrier discharge (DBD) plasma-catalysis for exothermic reactions is presented. DBD-plasma is used as reaction ignitor, rather than the classical approach of continuous ...
Co-Ni-carbon flexible composite fibres for directional magnetic actuation
