Oroxylum indicum, which is called Pheka in Thai, is a traditional Thai plant in the Bignoniaceae family with various ethnomedical uses such as as an astringent, an anti-inflammatory agent, an anti-bronchitic agent, an anti-helminthic agent and an anti-microbial agent. The young fruits of this plant have also been consumed as vegetables. However, there has been no report concerning its antibacte...

Zinc Oxide nanoparticles (ZnO-NPs) and graphene carbon material, due to lower drug resistance, can replace antibiotics, and by decorating of graphene with Zn-NPs, their properties can be greatly improved. The purpose of this study was to evaluate the antioxidant and antibacterial effects of ZnO-NPs biosynthesized using Crocus Sativus petal extract, graphene and graphene decorated by ZnO-NPs bio...

Background & Aims of the Study: Selenium is an essential nutritional material used for the important functions of the human body. The issue of the production of selenium nanoparticles (SeNPs) was investigated in various fields, such as anticancer, antioxidant, and antibacterial activities. Materials and Methods: In order to study antibacterial activity, the nutrient broth medium containing ...

Silver nanoparticles (Ag NPs) are known to have antibacterial properties. They are commonly produced by chemical synthesis which involves the use of harmful reducing agents. Contras, the laser technique is able to generate high-purity Ag NPs in water with specified surface charge characteristics. In the past, the molecular mechanisms contributing to the bactericidal effects of Ag NPs have been ...

Chemical studies of a streptomycete isolated from a cyanobacterium associated with the tropical tunicate Ecteinascidia turbinata led to the bioassay-guided purification of two antibacterial bisanthraquinone metabolites and a cytotoxic artifact. The structures, including relative configurations of these octacyclic compounds, were established by spectroscopic analyses. Their potent antibacterial ...

In the present work, metronidazole and doxycycline with different antibacterial spectra are proposed to be formulated as combination therapy to have a broader antibacterial therapy, which is effective against both aerobic and anaerobic periodontal microflora. Simultaneous use of metronidazole and doxycycline is effective against wide range of periodontal pathogens. Metronidazole and doxycycline...

The present study was carried out to investigate the preparation of chitosan-Ag nanocomposite filmfor food packaging. Since chitosan is a suitable alternative to produce packaging films due to favorablefactors such as biodegradability and abundance in the world, therefore in this study, it was preparedchitosan-Ag nanocomposite with antibacterial properties for food packaging b...

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), ...

the four full seasons & the various climates in our country iran, have certainly contributed to the variety of flora in iran, some of which demonstrate wonderful therapeutic effects. this is of particular interest when one considers such problems as antibiotic resistance and other side effects of synthetic drugs which have caused global interest in the growth of new disciplines such as pharmaco...

BACKGROUND Recent studies have demonstrated that several mineral products sold for medicinal purposes demonstrate antimicrobial activity, but little is known about the physicochemical properties involved in antibacterial activity. METHODOLOGY/PRINCIPAL FINDINGS Using in vitro mineral suspension testing, we have identified two natural mineral mixtures, arbitrarily designated BY07 and CB07, wit...
