in thoracolumbar spinal fractures with posterior column injury for applying proper management, it is important to distinguish a flexion-distraction injury (fdi) from a three column burst fracture (bf) as in clinical examination, both may have a similar significant tenderness on direct spinal palpation. careful attention to the comprehensive clinical examination and detailed imaging features are...

aerial parts of salvia mirzayanii was extracted with methanol. methanol extract was suspended in water and defatted with petroleum ether. the defatted part was then partitioned between ethyl acetate and water. the ethyl acetate partition was chromatographed on a silica gel column to afford several fractions. lymphocyte proliferation inhibitory assay of the resulted fractions was compared in vit...

In this paper, we consider the problem of fast and efficient dynamic scheduling of bursts that belong to different classes of priority in wavelength-division multiplexing (WDM)based optical burst switching (OBS) networks with limited optical buffers. In OBS networks, control and data components of a burst are sent separately with a time gap to ensure that resources such as wavelengths and fiber...

The authors report on the use of a burst-mode ultrashort pulsed laser source with an emitting wavelength 1030 nm to micro-machining plane areas glass different pulse durations, burst energies, and number sub-pulses per intra-burst rates 65 MHz 2.5 GHz. In investigated parameter range, maximum specific removal are obtained $$11.2\,\upmu \text{m}^{3}/\upmu \text{J}$$ for bursts $$27.0\,\upmu GHz ...

Objective(s):Despite of wide range applications of polymeric nanoparticles in protein delivery, there are some problems for the field of protein entrapment, initial burst and controlled release profile.   Materials and Methods: In this study, we investigated the influence of some changes in PLGA nanoparticles formulation to improve the initial and controlled release profile. Selected parameters ...

background and objectives: strains of shigella spp. can cause shigellosis, or bacillary dysentery.that is a public health problem worldwide. the aim of this study was to describe the population structure and genetic relatedness of multidrug resistant s. sonnei and s. flexneri isolated during a one year period from children with diarrhea in tehran, iran. materials and methods: a total of 70 shig...
