objective: the study was conducted to investigate the antibacterial and anthelmintic activities and to determine total phenolic contents of methanolic extract of piper betel leaves. materials and methods: the extract was subjected to assay for antibacterial activity using both gram positive and gram negative bacterial strains through disc diffusion method; anthelmintic activity with the determi...

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. dir...

The fate of bacteria in human urine was studied after inoculation of small numbers of Escherichia coli and other bacterial strains commonly implicated in urinary tract infection. Urine from normal individuals was often inhibitory and sometimes bactericidal for growth of these organisms. Antibacterial activity of urine was not related to lack of nutrient material as addition of broth did not dec...

background: innovative bioactive films incorporated with antimicrobial agents have been recently developed for food preservation. the aim of this study was to evaluate antibacterial activity of polylactic acid (pla) films incorporated with ziziphora clinopodioides essential oil (zeo) and ethanolic propolis extract (epe) against some common food-borne pathogens. methods: the volatile chemical co...

polymer nanocomposites containing metals have been used in a wide range of applications due to their versatility, and tunable characteristics including physical, chemical, biological and mechanical properties. in this research work polystyrene-silver nanocomposite has been produced using polymerization of a w/o microemulsion system. styrene monomer was used as the oil or continues phase of the ...
