Urine is one of the most common specimen types submitted to the clinical microbiology laboratory; the use of chromogenic agar is one method by which the laboratory might expedite culture results and reduce hands-on time and materials required for urine culture analysis. The objective of our study was to compare chromID CPS Elite (bioMérieux), a chromogenic medium, to conventional primary cultur...

Micro-propagation of olive provides the possibility of producing clones of native plants with appropriate attributes and mass reproduction in short period of time, compared to conventional methods. Apical dominance in olive explants limits the growth of lateral branches in vitro. The effect of Woody Plant Medium (WPM), Olive Medium (OM) and Murashig and Skoog (MS) with carbohydrate source (mann...

Several new superior apricot × plum (Prunus armenica × P. domestica) inter specific hybrid rootstocks have been recently produced in Iran, but the propagation of these hybrids by conventional means has been shown to be very difficult. In vitro propagation could be a reliable method for mass clonal propagation of these new rootstocks. In this study, in vitro establishment, proliferation and root...

     The bone mineral consists of tiny hydroxyapatite (HA) crystals in the nanoregime. Nanostructured HA is also expected to have better bioactivity than coarser crystals. This paper reports on the in vitro evaluation of bone like HA nanopowders. The prepared HA nanopowder was characterized for its phase purity, chemical homogeneity and bioactivity. Fourier transform infrared (FT-IR) s...

Nature has exploited medium-sized 8- to 11-membered rings in a variety of natural products to address diverse and challenging biological targets. However, owing to the limitations of conventional cyclization-based approaches to medium-ring synthesis, these structures remain severely underrepresented in current probe and drug discovery efforts. To address this problem, we have established an alt...

Introduction: Digital radiography possesses a wide dynamic range and has a major advantage in producing an acceptable image of diagnostic value even though overexposure occurs. Lumbar spine (LS) radiography is the most common examinations that gives high radiation dose to patients and accounts for the highest collective population dose of any conventional radiographic ...

Presuppositions are very important in our understanding of how background and context determine the interpretation of a sentence. However, if we study some of the things that have been claimed to be presuppositions, we find that it is a very miscellaneous collection of things. Here are some examples: (1) Harry saw the man kiss her presupposes that Harry and the man denote uniquely existing, for...

Background: The buffalo (Bubalus bubalis) is the animal with special production characteristics in producing milk and meat has a critical role in rural industry in Iran. The most problem of this specie is its low reproductive output. The aim of the present study was to evaluate the effect of bovine cumulus co-culture on maturation rate of Buffalo oocyte.Materials and Methods: Ovaries were colle...

A simulated curved root canal in a resin block was enlarged to size 40 and used to compare the depth of accessory cone penetration and weight of obturation occurring with the use of different obturation techniques and spreader-accessory cone combinations. Twelve groups, each consisting of 10 obturations, were created. A conventional lateral condensation technique was used in six groups and a me...
