background and aims. triple antibiotic paste (tap) is widely used in endodontics for root canal disinfection, particularly in regenerative procedures. the aim of this in vitro study was to evaluate the antimicrobial effects of different concentrations of tap at 1-, 2-, 3-, and 4-week intervals on mature enterococcus faecalis biofilm. materials and methods. a total of 287 extracted one-rooted hu...
echinoderms are independent and quite special branch of world animals. sea cucumbers are among the strangest members of echinoderm class regarding their structure and physiology. these fauna have been tested with regard to anti-bacterial, anti-fungal, anti-coagulants, anti-virus, cytotoxic, hemolytic and anti-hiv features. in this study, the antibacterial activity of holothuria leucospilota sea...
the edible mushrooms (basidomycetes) have high nutritional value, promote the immune system, and as a source of natural antimicrobial substances have been used to cure bacterial infections since ancient times.various kinds of proteins with several biological activities are produced by mushrooms. in this research, in order to evaluate antibacterial activity of edible mushrooms, we isolated prote...
conclusions: with respect to the obtained results and regarding to the daily increase of the resistant microbial strains to the commercial antibiotics, it can be concluded that these extracts can be proper candidates of antibacterial substance against pathogenic bacterial species especially s. aureus, e. coli, k. pneumoniae and s. epidermidis. results: the extract of c. fistula was effective ag...
Cranberry-derived compounds, including a fraction known as proanthocyanidins (PACs) exhibit anti-microbial, anti-infective, and anti-adhesive properties against a number of disease-causing organisms. In this study, the effect of cranberry proanthocyanidins (CPACs) on the infection of epithelial cells by two enteric bacterial pathogens, enteropathogenic Escherichia coli (EPEC) and Salmonella Typ...
PURPOSE The aim of the present study was preparation, physicochemical characterization and performance evaluation of gold nanoparticles (GNPs) in radiotherapy. Another objective was the investigation of anti-bacterial efficacy of gold nanoparticle against E. coli clinical strains. METHODS Gold nanoparticles prepared by controlled reduction of an aqueous HAuCl4 solution using Tri sodium citrat...
Abstract Background: Human beings have always used plants to cure diseases. Recently, some researches have revealed that Thymbra spicata’s essential oils contains Carvacrol and Thymol both of these compounds have anti-bacterial effects. In this study, we aimed to investigate the anti-bacterial properties of the essential oil of Thymbra spicata a native plant of Ilam province. Materials and ...
Neuro-inflammation, biochemical and cellular responses of the nervous system to injury, infection or neurodegenerative diseases, is a major risk factor for Alzheimer's, Parkinson's and Multiple Sclerosis. Periodontitis is a serious bacterial gum infection that damages the soft tissue and teeth supporting bones, causing teeth loss. It also renders systemic inflammation by secretion of pro-inflam...
A series of potent antibacterial agents have been prepared. These agents are penems carrying a lactone ring in the C-2 position. Excellent activity against Gram-positive and Gram-negative organisms--except Pseudomonas aeruginosa--was found.
