Ten herbal products, made up of five powdery and liquid samples different brands, were assessed microbiologically for the presence types microorganisms. Qualitative quantitative phytochemical screening above was also conducted to verify or absence bioactive components. bacterial species, viz: Bacillus subtilis, Staphylococcus aureus, Salmonella typhi, Shigella dysenteriae, Pseudomonas aeruginos...

Novel N-halamine nanoparticles potentially useful for killing pathogenic bacteria, i.e., SiO2@PS/N-halamine NPs, were successfully synthesized via the immobilization of N-halamines onto the polystyrene-coated silica nanoparticles (SiO2@PS NPs). The effect of reaction conditions, i.e., chlorination temperature, bleaching concentration, chlorination time, on the oxidative chlorine content in the ...

introduction: the main goal of endodontic treatment is elimination of bacteria and their by-products from infected root canals. this study compared the antibacterial effect of two different sealers, ah 26 and mta fillapex, on 4 microorganisms 24, 48 and 72 h and 7 days after mixing. methods and materials: the microorganisms used in this study consisted of lactobacillus acidophilus ( atcc 4356),...

     White spot lesions are observed in nearly 50% of patients undergoing orthodontic treatment. Long-lasting antibacterial properties of orthodontic cements can reduce this phenomenon. The aim of this research was to compare antimicrobial activity of three commercial glass ionomer cements with three commercial zinc phosphate cements, over time, against streptococcus mutans and candida albicans...

This study evaluated the effect of EDTA and lysozyme on the antibacterial activities of activated ovotransferrin against 5 strains of Listeria monocytogenes. First, a disc test was performed to screen the concentrations of EDTA or lysozyme that showed antibacterial activities in ovotransferrin (O) or ovotransferrin in 100 mM NaHCO3 (OS) solution. Turbidity and viability tests were conducted usi...

A series of various novel 4-arylthiophene-2-carbaldehyde compounds were synthesized in moderate to excellent yields via Suzuki-Miyaura cross-coupling with different arylboronic pinacol esters/acids. The synthesized products were screened for their antibacterial, haemolytic, antiurease, and nitric oxide (NO) scavenging capabilities and interestingly, almost all products turned out to have good a...
