introduction: osteosarcoma is the most common primary bone tumor in children and young adults and appropriate chemotherapy can increase limb sparing and overall survival. yet, the toxicity of chemotherapy regimens including mtx can be life threatening. therefore; we tried another chemotherapy regimen for these patients. method and materials: we investigated 15 patients aged 15 to 40 years old a...

background: in the past 20 years, a dramatic improvement in the prognosis of patients with hepatoblastoma (hb)has been achieved by combining surgery and chemotherapy in several national and international trials.materials and methods: four children ( 3 girl and 1 boy) aged 34 days, 4 months, 13 months, and 1 year with meanage of 6.53 (±5.15) months were presented to our center from 2002 to 2009 ...

ZnO and Mn-ZnO nano powders were prepared by the sol-gel auto combustion method. The products were characterized by X-ray diffraction (XRD), energy dispersive analysis of X-ray (EDX) and scanning electron microscopy (SEM). Structural and morphological properties of nano particles were investigated and the average crystalline size of ZnO and Mn-doped ZnO was obtained 44 and 51 nm, respectively. ...

We propose photo-BJMOSFET (Bipolar Junction Metal-Oxide-Semiconductor Field Effect Transistor) fabricated on SOI film. ITO film is adopted in the device as gate electrode to reduce light absorption. I-V characteristics of photo-BJMOSFET obtained in dark (dark current) and under 570nm illumination (photo current) are studied furthermore to achieve high photo-to-dark-current contrast ratio. Two v...

This article examines the value of using the photo-elicitation method for generating health-related narratives. Drawing on research in which women kept a photographic record of their experiences of chemotherapy treatment for breast cancer, this research explored how this method (a) produced elaborate accounts of illness experiences through an exploration of the process of representing experienc...
