In an attempt to combat the possibility of bacterial infection and insufficient bone growth around metallic, surgical implants, bioactive glasses may be employed as coatings. In this work, silica-based and borate-based glass series were synthesized for this purpose and subsequently characterized in

Spiro derivatives of oxindole and isoxazole-5-one were synthesized by using Michael addition reaction, highlighting the regioselective approach towards the synthesis of Michael diadduct followed by condensation of Michael diadduct. The spiro compound 4 showed antitubercular activity against

316L stainless steel is widely used for fashion jewelry but it can carry a large number of bacteria and cause the potential risk of infection since it has no antimicrobial ability. In this paper, La is used as an alloying addition. The antibacterial capability, corrosion resistance and

The liberation of endotoxin from Escherichia coli by the addition of antibiotics was investigated using a new method of limulus test, i.e. dry up method. The addition of the bactericidal antibiotic, aminobenzylpenicillin or streptomycin sulfate, to the suspension of Escherichia coli (about 10(6)/ml)

Six strains of Staphylococcus aureus have been studied using an original method which associate the chessboard's technique to that of bactericidal kinetic's. Associations of pefloxacin and rifampicin, vancomycin and fosfomycin are analysed, and result of each concentration's connection is expressed,

PEG-based hydrogels possess tissue-like mechanical elasticity, solute permeability, cytocompatibility and biocompatibility. In this work, PEG-based hydrogels were prepared via nucleophilic thiol-yne addition between a 4-arm PEG functionalized with thiols (PEG10k-4-SH) and an electron-deficient

The aim of this study was to evaluate the effect of the addition of antibacterial agents to composites on color changes after immersion of these composites in different beverages.

Composite resins containing antibacterial agents

Most of the magnesium (Mg) alloys possess excellent biocompatibility, mechanical property and biodegradability in orthopedic applications. However, these alloys may suffer from bacterial infections due to their insufficient antibacterial capability. In order to reduce the post-surgical infections, a

Pertussis is a highly contagious respiratory disease that is especially dangerous for infants and children. Despite mass vaccination, reported pertussis cases have increased in the United States and other parts of the world, probably because of increased awareness, improved diagnostic means, and

Amylose films blended with chitosan, which were free from additives such as acid, salt, and plasticizer, were prepared by casting mixtures of an aqueous solution of an enzymatically synthesized amylose and that of water-soluble chitin (44.1% deacetylated). The presence of a small amount of chitin

The objectives of this study were to evaluate physical properties and antibacterial activity of a light-activated composite modified with silver nanoparticles. Discs were produced with unmodified resin (control group - CG) and modified resin with silver nanoparticles at two concentrations, 0.3% wt

The effects of addition of different Cu content (0, 2.5 and 3.5wt%) on mechanical properties, corrosion resistance and antibacterial performance of 316L austenitic stainless steel (SS) after solution and aging treatment were investigated by mechanical test, transmission electron microscope (TEM),

A general synthetic sequence involving simply prepared starting materials provides rapid access to diverse, novel tricyclic architectures inspired by pleuromutilin. Sm(II) -mediated radical cyclization cascades of dialdehydes, prepared using a new, one-pot, copper-catalyzed double organomagnesium

OBJECTIVE The aim of this study was to evaluate the addition of titanium dioxide (TiO(2)) nanoparticles to a conventional glass-ionomer (GI) on physical and antibacterial properties. METHODS TiO(2) nanoparticles were incorporated into the powder component of Kavitan(®) Plus (SpofaDental, Czech
