INTRODUCTION High-intensity focused ultrasound (HIFU) produces collapsing cavitation bubbles. This study aims to investigate the efficacy of collapsing cavitation bubbles to deliver antibacterial nanoparticles into dentinal tubules to improve root canal disinfection. METHODS In stage 1, experiments were performed to characterize the efficacy of collapsing cavitation bubbles to deliver the min...
The rising number of antibiotic-resistant bacterial strains represents an emerging health problem that has motivated efforts to develop new antibacterial agents. Endogenous cationic antibacterial peptides (CAPs) that are produced in tissues exposed to the external environment are one model for the design of novel antibacterial compounds. Here, we report evidence that disubstituted dexamethasone...
background: mentha piperita l. essential oils have different antibacterial activity. in the present study, we investigated the effect of γ–irradiation on the antibacterial activities of mentha piperita l. essential oils in vitro and in vivo systems. materials and methods: the aerial parts of peppermint were irradiated in a cobalt60 source with 0, 10 and 25 kgy absorbed doses. then, the plants w...
abstract background antibiotic resistance makes antimicrobial peptides (amps) agents an alternative for treatment of pathogenic diseases. they are isolated from various animals invertebrates, vertebrates and plants. the present study shows the electrophoretic pattern of protein and peptides from vicia faba seed and reports our first attempt to study the antibacterial activity of vicia faba seed...
introduction: aloe vera compounds have inhibitory activity on fungi, bacteria, and viruses. this study examines the antibacterial activity of a. vera purified extracts including gel, boiled skin, boiled gel, and distilled extract against pathogenic bacteria, staphylococcus aureus, methicillin-resistant s. aureus (mrsa), klebsiella pneumonia and pseudomonas aeruginosa were elucidated. method: th...
In order to solve the challenging problem of microbial infections caused by microorganisms on medical implants, it is imperative to develop novel antimicrobial biomaterials. This work demonstrated that 317L-Cu stainless steel (SS), created by adding copper through a solution and aging heat treatment process, exhibited good antibacterial properties against staphylococcus aureus, achieving 2 log ...
INTRODUCTION Issues pertaining to the effective elimination of bacterial biofilm and disruption of biofilm structure still remains in endodontic disinfection. Nanoparticulates such as chitosan (CS-np) and zinc oxide (ZnO-np) are known to possess significant antibacterial properties. This study aimed to test (1) the efficacy of CS-np and ZnO-np in disinfecting and disrupting biofilm bacteria and...
This study examined the effects of storage conditions such as time course, temperature, fluorescent light, and darkness on the components and antibacterial activity of formalin guaiacol (FG) used in endodontic treatment. We measured the quantities of formaldehyde and guaiacol in FG and antibacterial activities against Staphylococcus aureus, Porphyromonas gingivalis, and Porphyromonas endodontal...
BACKGROUND AND OBJECTIVES Antibiotic therapy is the main choice in treatment of Escherichia coli induced infections. Using herbal medication is an alternative choice in treatment of diseases. The aim of this study was to determine the antibacterial activity of two traditionally used herbs in Iranian medicine, Anacyclus pyrethrum and Pistacia lentiscus L., on Escherichia coli. MATERIALS AND ME...
BACKGROUND The recent report of high numbers of Acinetobacter baumannii bloodstream infections among service members injured in Iraq and Afghanistan during the period January 2002 through August 2004 has prompted an investigation into their etiology. A review of the current guidelines for open combat casualty wounds as part of this broad investigation was not mentioned in the report. OBJECTIV...
