fractions obtained from partitioning of aerial methanolic extract of euphorbia aellenii with chloroform (e2), ethyl acetate (e3), n-butanol (e4) and water (e5) were investigated in vitro for their phytotoxicity, insecticidal, anti-leishmanial, cytotoxicity, antibacterial and antifungal activities. sample e2 appeared to have significant phytotoxic activity. in the insecticidal screening study on...

antibacterial activity of the aerial extracts from xanthium brasilicum prepared in methanol, diethyl ether, petroleum benzene and an equal mixture of the three solvents were studied against bacterial laboratory standards and clinical isolates using the disk diffusion method. the best antibacterial results were obtained when methanol or the solvent mixture was used. the crude extract with the hi...

Lactoferricin B is a cationic antimicrobial peptide derived from the N-terminal part of bovine lactoferrin. The effect of bacterial proteases on the antibacterial activity of lactoferricin B towards Escherichia coli and Staphylococcus aureus was investigated using various protease inhibitors and protease-deficient E. coli mutants. Sodium-EDTA, a metalloprotease inhibitor, was the most efficient...

The action and interaction of benzylpenicillin and gentamicin on Streptococcus faecalis was studied using mainly turbidimetric methods. The minimum antibacterial concentration (MAC) of each antibiotic lay considerably below the conventionally determined minimum inhibitory concentration, and levels of the two agents exceeding the MAC were necessary in order to obtain a synergic interaction. Evid...

Cases of synergic Urinary Tract Infections with its associated ailments has become a menace. Due to high costs treatment, unavailability relevant antibiotics, misdiagnosis and recurrence, most patients within Africa Sub-Sahara regions prefer ethnopharmacological ways taking boiled sieved liquid concoction made from mature leaves (ML) ricinus communis clear the urinary tract system these microbe...

background drug resistance of microorganisms to antimicrobial agents is on the rise. therefore, an alternative route to overcome drug resistance of various microorganisms is needed. objectives this study was conducted to assess antibacterial activity of silver nanoparticles (agnps) produced by satureja hortensis extract against bacillus cereus isolated from soil of sistan plain (zabol, southeas...

the resistance of antimicrobials has become a global hazard with the irrational use of antibiotics. infection of drug-resistance bacteria seriously threatens human health. currently there is an urgent need for the development of novel antimicrobial agents with new mechanisms and lower levels of toxicity. in this paper, a series of (s,z)-4-methyl-2-(4-oxo-5-((5-substitutedphenylfuran-2-yl) methy...

A 100% increment of antibacterial ability has been achieved due to significant synergic effects of boron-doped diamond (BDD) anode and reduced graphene oxide (rGO) coupled in a three dimensional electrochemical oxidation system. The rGO, greatly enhanced by BDD driven electric field, demonstrated strong antibacterial ability and even sustained its excellent performance during a reasonable perio...

background: in recent years, plants natural products have gained considerable attention as natural preservers for use in different industries. due to their free radical scavenging activities, phenolic compounds can prevent a wide range of diseases such as cancers and cardiovascular and neurodegenerative diseases. for a long time, different ferulago species have been in use as medicinal plants w...

Calcium phosphate cements (CPCs) have several advantages for use as endodontic materials, and such advantages include ease of use, biocompatibility, potential hydroxyapatite-forming ability, and bond creation between the dentin and appropriate filling materials. However, unlike tricalcium silicate (CS)-based materials, CPCs do not have antibacterial properties. The present study doped a nonwash...
