background and objective: early determination of antibacterial susceptibility increases the success of therapy, decreases unnecessary use of antibacterial agents and side-effects, and lowers the overall healthcare cost. materials and methods: a rapid colorimetric method for antibacterial susceptibility testing named qui-sensitest (inovative biotechnology organization, istanbul, turkey) was eval...

we derive closed formulas for the prices of european options andtheir sensitivities when the underlying asset follows a double-exponentialjump diffusion model, as considered by s. kou in 2002. this author hasderived the option price by making use of double series where each termrequires the computation of a sequence of special functions, such thatthe implementation remains difficult for a large...

results the minimal inhibitory concentration (mics) values of myrtus communis leaves extract ranged 0.625-5.0 µg/µl and 5-40 µg/µl against tested candida spp. and aspergillus spp., respectively. conclusions results revealed that the ethanolic extract of myrtus communis leaves have antifungal potency against both pathogenic tested fungi, and it can be used as a natural antifungal agent. material...

background and purpose: the status of medicinal plants in iranian traditional medicine and rich existence of herbal sources, on one hand, and current problems in curing infections, on the other hand, are the factors to study medicinal plants more accurately. tarragon (artemisia dracunculus l.) is a herbaceous plant from asteraceae family, available in planted and farming forms in iran. this stu...

background: gliomas are the most common primary neoplasms of the central nervous system. relative cerebral blood volume (rcbv) could estimate high-grade gliomas computed with dynamic susceptibility contrast mr imaging which it is artificially lowered by contrast extravasation through a disrupted blood-brain barrier. objectives: our intent was to clarify the usefulness of diffusion-weighted magn...

background and objective: methicillin resistance in staphylococcus aureus is an increasingly important clinical problem. a chromosomal gene, meca, mediates resistance to penicillinase-resistant penicillins such as methicillin and oxacillin in staphylococcus aureus. we evaluated the validity of disk diffusion test by using oxacillin, methicillin and cefoxitin disks with consideration of the pres...

nanofiltration-based separation processes have found diverse applications in industrial and environmentalproblems recently, due to several advantages such as lower energy requirement and elevated flux ratescompared with their reverse osmosis (ro) counterparts. several attempts have been made for modellingnf-based separation processes ranging from rigorous space-charge approaches to simpler irre...
