introduction: jejunoileal atresia (jia) is a common cause of neonatal intestinal obstruction and is a common surgical emergency. the aim of this study was to compare primary anastomosis without resection of the dilated segment with transanastomotic t tube jejunostomy (tatto) versus resection of the dilated segment without t tube as the control group for treatment of patients with jia. material ...

disordered t-shaped graphene nanodevice (tgn) was designed and studied in this paper. we demonstrated the intrinsic transport properties of the tgn by using landauer approach. knowing the transmission probability of an electron the current through the system is obtained using landauer-buttiker formalism. the effects of single disorder on conductance, current and on the transport length scales a...

in this study, selenium was recovered from an industrial dust. after the purification process, the researchers were able to prepare selenium micro powder. the objective of this study was to prepare selenium nano particles by water solution phase method from the micro powders. the results showed that selenium micronized powder and nano particles had high purity. the obtained nanoparticles were t...

Fascioliasis is a rare zoonotic infection caused by Fasciola hepatica, and presents with atypical clinical manifestations including fever, ambiguous gastrointestinal symptoms and right upper quadrant pain. Blood tests often reveal elevated eosinophilia. However, it may be misdiagnosed as intrahepatic chaolangiocarcinoma on radiologic findings. In this study, we presented a 41-year-old female pa...

the effect and arrangement of cytoskeleton (microtubules, microfilaments and neurofilaments) in neurulation of chick embryo examined by immunoperoxidase method from stage 6 to stage 12. the results were as follows: 1) microtubules aggregated in the perinuclear region from which they radiated to take longitudinal course beneath the membrane. 2) microfilaments were aggregated in the apical ends (...

Micromixers are one of the most crucial components of Lab-On-a-Chip devices with the intention of mixing and dispersion of reagents like small molecules and particles. The challenge facing micromixers is typically insufficient mixing efficiency in basic designs, which results in longer microchannels. Therefore, it is desirable to increase mixing efficiency, in order to decrease mixing length, w...
