conclusions potato peels were proved to be potentially useful substrates for biosurfactant production by b. pumilus dsvp18. the strain possessed a unique property to reduce surface tension of the media from 72 to 28.7 mn/m. in addition, it showed a stable surface activity over a wide range of temperatures, ph, and saline conditions and had strong antimicrobial activity. this potential of the id...

background: escherichia coli o157:h7 is a gram-negative and facultative anaerobic food-borne bacterial pathogen. the major purpose of this study was to evaluate physicochemical characteristics of nanoliposome garlic essential oil (eo) and its antibacterial effect on e. coli o157:h7. methods: nanoliposome garlic eo was prepared by ethanol injection method and its physicochemical properties were ...

Breast cancer is the most common malignancy in women worldwide. associated with a high mortality rate and health-related economic burden. patients have low 5-year life expectancy when diagnosed at advanced stages. Besides, emergence of chemoresistance breast has led to an intense search for alternative anticancer agents. One potential compounds Piperine. Several studies had found that Piperine ...

in many acute leukemias, normal differentiation does not occur. however, in many cell lines derived from hematologic malignancies, differentiation or apoptosis can be induced by variety of agents. despite advances in the treatment of acute lymphoblastic leukemia (all), in most patients long-term survival rates remain unsatisfactory, especially in t-cell derived all. thus we studied the anti-can...

there has been special interest in the chemistry of quinolone and pyrimidine derivatives due to their diverse biological activities such as anticonvulsant, anti-malarial agents, antibacterial, antiviral, cytostatic, antithelemintic, antigenotoxic, anti-cancer agents. these compounds are also used as targeting delayed-type hypersensivity and anti-convulsant agents. as a part of our research work...

peperomia pellucida leaf extract was characterized for its anticancer, antimicrobial, antioxidant activities, and chemical compositions. anticancer activity of p. pellucida leaf extract was determined through colorimetric mtt (tetrazolium) assay against human breast adenocarcinoma (mcf-7) cell line and the antimicrobial property of the plant extract was revealed by using two-fold broth micro-di...
