(Bioactive Materials, 2021-12)Bacterial infection of implanted scaffolds may have fatal consequences and, in combination with the emergence of multidrug bacterial resistance, the development of advanced antibacterial biomaterials ... -
Antibacterial coatings on titanium surfaces: a comparison study between in vitro single-species and multispecies biofilm
(ACS applied materials and interfaces, 2015)Dental plaque is a biofilm that causes dental caries, gingivitis, and periodontitis. Most of the studies in antibacterial coatings have been conducted by in vitro single-species biofilm formation, but ... -
Antimicrobial peptides: powerful biorecognition elements to detect bacteria in biosensing technologies
(Molecules, 2018-07-10)Bacterial infections represent a serious threat in modern medicine. In particular, biofilm treatment in clinical settings is challenging, as biofilms are very resistant to conventional antibiotic therapy ... -
Citric acid in the passivation of titanium dental implants: corrosion resistance and bactericide behavior
(Materials, 2022)The passivation of titanium dental implants is performed in order to clean the surface and obtain a thin layer of protective oxide (TiO2) on the surface of the material in order to improve its behavior ... -
Delayed cerebral vasculopathy in pneumococcal meningitis: epidemiology and clinical outcome. A cohort study
(International Journal of Infectious Diseases, 2020-08)Background: To describe the prevalence, clinical characteristics, impact of systemic steroids exposure and outcomes of delayed cerebral vasculopathy (DCV) in a cohort of adult patients with pneumococcal ... -
Detection and expression analysis of tet(B) in streptococcus oralis
(Journal of Oral Microbiology, 2019)Tetracycline resistance can be achieved through tet genes, which code for efflux pumps, ribosomal protection proteins and inactivation enzymes. Some of these genes have only been described in either ... -
Determination of fluid leakages in the different screw-retained implant-abutment connections in a mechanical artificial mouth
(Journal of Materials Science: Materials in Medicine, 2015-07-15)This study shows the potential risk of microfiltration between two different types of implant-abutment connections screwed at 45 Ncm: external and internal. For the first time the use of a mechanical ... -
Engineering a genome-reduced bacterium to eliminate Staphylococcus aureus biofilms in vivo
(Molecular Systems Biology, 2021)Bacteria present a promising delivery system for treating human diseases. Here, we engineered the genome-reduced human lung pathogen Mycoplasma pneumoniae as a live biotherapeutic to treat biofilm-associated ... -
Evaluation of bone loss in antibacterial coated dental implants: an experimental study in dogs
(Materials Science and Engineering: C, 2016-12)The aim of this study was to evaluate the in vivo effect of antibacterial modified dental implants in the first stages of peri-implantitis. Thirty dental implants were inserted in the mandibular premolar ... -
Nasopharyngeal microbiota in children with invasive pneumococcal disease: identification of bacteria with potential disease-promoting and protective effects
(Frontiers in Microbiology, 2019)Background and Aims: The risk of suffering from some infectious diseases can be related to specific microbiota profiles. Specifically, the nasopharyngeal microbiota could play a role as a risk or ... -
New bactericide orthodonthic archwire: NiTi with silver nanoparticles
(Metals, 2020)A potential new bactericide treatment for NiTi orthodontic archwires based in the electrodeposition of silver nanoparticles on the surface was studied. Twenty-five archwires were treated by electrodeposition, ... -
Optimization of titanium dental mesh surfaces for biological sealing and prevention of bacterial colonization
(Materials, 2022)Titanium dental meshes have a wide application in order to ensure the retention of calcium phosphate-based biomaterials to regenerate bone tissue. These meshes are temporary and must grow a soft tissue ... -
Polyethylene glycol pulsed electrodeposition for the development of antifouling coatings on titanium
(Coatings, 2020)Titanium dental implants are widely used for the replacement of damaged teeth. However, bacterial infections at the interface between soft tissues and the implant can impair the functionality of the ... -
Rapid molecular syndromic testing for aetiological diagnosis of gastrointestinal infections and targeted antimicrobial prescription: experience from a reference paediatric hospital in Spain
(European Journal of Clinical Microbiology & Infectious Diseases, 2021)Aetiological diagnosis of gastrointestinal infections is challenging since a wide range of bacteria, parasites and viruses can be causal agents and derived clinical manifestations appear quite similar. ... -
