BACKGROUND Carissa opaca Stapf ex Hanes fruits is traditionally used in the treatment of asthma, hepatitis and microbial infections. The present study was arranged to investigate the antimicrobial, cytotoxic and antitumor activity of various fractions of C. opaca extract and its bioactive metabolites responsible for that activity. METHODS To characterize various fractions of C.opaca antibacte...

In orthodontics effective disinfection of pliers in short time is important. We aimed to evaluate the effectiveness of three disinfectant solutions (two quaternary ammonium compounds (Deconex, Micro10+) and one hydrogen peroxide disinfectant (Sanosil)) in orthodontic pliers’ disinfection.

The cellulosic fabrics bearing the porphyrin as a photo-sensitizer were done in order to prepare efficient polymeric materials for antimicrobial applications. The obtained porphyrin-grafted cellulosic fabrics were characterized by ATRFTIR, DRUV spectroscopy, TG and SEM image. The antimicrobial activity of the products was tested under visible light irradiation against Staphylococcus aureus, Pse...

objective(s): a large ratio of surface to volume of nanoparticles in comparison with bulk ones, will increase the cell penetration and therefore their toxicity. materials and methods: chemical precipitation method was used in order to synthesis of zns:ag quantum dots. their physical properties and characteristics were assessed by x-ray diffraction, ultra violet-visible spectrophotometer, transm...

Twin brothers aged 9-years were seen over a period of 5-years and were diagnosed and treated as atopic dermatitis. They came to our attention due to repeated exacerbations of dermatitis and multiple skin abscesses. Physical examination showed that both the brothers had coarse facial appearance with prominent brow and deep-set eyes (Figure 1). There were papulopustular lesions all over the body ...

The focus of this study was to isolate and to identify the actinomycetes having antimicrobial activity. A total of 145 actinomycetes were recovered from soil samples collected from different areas in Tamilnadu, India. All these isolates were screened for their antimicrobial activity against Staphylococcus aureus, Escherichia coli, Pseudomonas aeroginosa, Klebsiella pneumonia and Candida albican...
