The objective of this study was to evaluate the antifungal activity of essential oil (EO) of Eucalyptus camaldulensis Dehnh. against five Fusarium spp. commonly associated with maize. The essential oil had been extracted by steam distillation in a modified Clevenger-type apparatus from leaves of E. camaldulensis and their chemical composition characterized by gas chromatography mass spectrometr...

Nowadays, uncontrolled and frequent use of antibiotics may cause emergence of microbial resistanceamong pathogenic agents. Therefore, the use of new synthetic and natural antimicrobial compounds isinevitable. One source of natural compounds in this respect comes from plants. The purpose of this study was to examine the antibacterial effects of peel extracts from sour and sweet pomegranate. Meth...

In recent years, the spread of drug-resistant strains of Streptococcus pneumoniae, as the most common causes of bacterial respiratory infections, threatens public health. Therefore, the use of new antimicrobial medicines to inhibit this pathogen is an urgent demand. In this research project, the inhibitory effects of thirty recently synthesized compounds including thiazole, thiazolidine, imidaz...

Garcinia atroviridis (Clusiaceae) has been used as a postpartum medication agent in folkloric medicine. However, its biological potential has not been fully evaluated. The present study was aimed to evaluate the antioxidant efficacies, cholinesterase enzyme inhibitory and antimicrobial activity of the stem bark extracts of G. atroviridis. Successive extraction was done using solvents of varied ...

Minimum alveolar concentration (MAC), served as the vital concept for standard measure of potency for inhaled volatile anesthetic agents, has been employed in anesthetic practice for more than 50 years. A re-consideration in the connotation and influence factors on MAC is introduced in this article. MAC actually indicates “median effective dose (ED50) for immobility”, but it is at least not com...

in different folk medicine ziziphus spina-christi is used for different purposes such as pneumonia, dysentery, scorpion stings, cough, constipation, intestinal worms and fever. the aim of this study was evaluation and comparing the antibacterial activity of methanolic and ethanolic extracts of ziziphus spina –christi as well as subsequent structural changes in affected bacteria. for this purpos...

Optimization of the continuous fermentation process is important for increasing efficiency and decreasing cost, especially complicated biochemical processes described by substrate product inhibition. The optimum design (minimum volume) CSTRs in series assuming inhibition was determined this study. effect operating parameters on investigated. concentration feed to first reactor N reactors series...
