background: the problem of bone defects during treatments of bone lesions, especially cranial trauma, and also during craniotomy operations indicates isolation of osteoblasts and culturing them for filling these bone effects. methods: bone tissue specimens were obtained from 6 patients’ carvaria undergoing craniotomy surgery operations in al-zahra teaching hospital and transferred to lab. these...

background: the purpose of this study was to investigate the enhanced thermal resistance mechanism of the du145 tumor spheroid cultures as compared to the prostate carcinoma cell line's monolayer cultures. materials and methods: du145 cells were cultured either as spheroids or monolayers. cultures were treated with hyperthermia in a precision water bath (at 43°c for 60 minutes) and/or quercetin...

gaz-angubin is a sweet exudate naturally produced by an insect from the gavan-e-gaz-angubin plant. adsorption and desorption isotherms for a gaz-angubin sample were determined at 15° and 25°c over a range of relative humidity from 0 to 90% using a dynamic vapor sorption system. at different levels of relative humidity, changes in sample mass were continuously measured versus time and described ...

We study kinetically controlled orientational and structural transitions of molecular thin films during growth in situ and in real time, using diindenoperylene (DIP) as an example. By time-resolved surface-sensitive x-ray scattering (out of plane and in plane), we follow the organic molecular beam deposition of DIP on silicon oxide, on stepped sapphire, and on rubrene as an organic model surfac...

Self-assembled two-dimensional arrays of either 14 nm hcp-Co or 6 nm ε-Co particle components were treated by hydrogen plasma for various exposure times. A change of hysteretic sample behavior depending on the treatment duration is reported, which can be divided in two time scales: oxygen reduction increases the particle magnetization during the first 20 min, which is followed by an alteration ...
