in the last century, neural stem cells are used in a lot of studies for basic and therapeutic investigations. several sources are identified for neural stem cells including embryonic, fetal and adult stem cells. although most of studies have focused in embryonic as well as fetal cells due to their capacity to generate progenies, these cells have some problems such as immunological, availability...

background and objective: temporal lobe epilepsy is hallmarked with neuronal degeneration in some areas of hippocampus and mossy fiber sprouting in dentate area. considering some evidences on neuroprotective and antioxidant activity of silymarin (sm), this study was undertaken to evaluate the preventive effect of this agent on structural changes in hippocampus of kainate-epileptic rats. materia...

background morphometric data of the frontal lobe are important for surgical planning of lesions in the frontal lobe and its surroundings. magnetic resonance imaging (mri) techniques provide suitable data for this purpose. objectives in our study, the morphometric data of mid-sagittal mri of the frontal lobe in certain age and gender groups of children have been presented. patients and methods i...

congenital lobar emphysema is a rare cause of respiratory distress during infancy which is cured by surgery. we are reporting three cases of congenital lobar emphysema with different presentations of the disease. chest x-ray was the basis of diagnosis but confirmatory lung computerized tomography was also used. the emphysematous lobe was left upper lobe in two infants and right upper and middle...

We describe the microfluidic assembly of soft dimer capsules by the fusion of individual capsules with distinct properties. Microscale aqueous droplets bearing the biopolymer chitosan are generated in situ within a chip and, as they travel downsteam, pairs of droplets are made to undergo controlled cross-linking and coalescence (due to a channel expansion) to form stable dimers. These dimers ar...

The DNA of Cryptosporidium Oocysts was extracted from fecal samples by using Commercial Wizard Genomic DNA purification general kit, tow freezingthawing protocols have been compared in this study: deep freezer for three cycles and liquid nitrogen for fifteen cycles, the results indicate that the second protocol was more influential in obtaining a sufficient amount of DNA from Oocysts of Cryptos...
