Neuroblastoma is a pediatric malignancy with a poor prognosis at least partly attributable to an early pattern of dissemination. New approaches to treatment of micrometastases include targeted radiotherapy using radiolabeled antibodies or molecules which are taken up preferentially by tumor cells. Multicellular tumor spheroids (MTS) resemble micrometastases during the avascular phase of their d...

The mechanism of N-acetyl-p-benzoquinone imine (NAPQI)-induced release of Ca2+ from rat liver mitochondria was investigated. The addition of NAPQI or 3,5-Me2-NAPQI (a dimethylated analogue of NAPQI with only oxidizing properties) to mitochondria resulted in the rapid and extensive oxidation of NADH and NADPH. High-performance liquid chromatographic analysis of mitochondrial pyridine nucleotides...

Neuroblastoma is unique amongst common pediatric cancers for its expression of the norepinephrine transporter (NET), enabling tumor-selective imaging and therapy with radioactive analogues of norepinephrine. The majority of neuroblastoma tumors are avid for (123)I-metaiodobenzaguanidine (mIBG) on imaging, yet the therapeutic response to (131) I-mIBG is only 30% in clinical trials, and off-targe...

The range-separated hybrid density functionals are very successful in describing a wide range of molecular and solid-state properties accurately. In principle, such functionals are designed from spherically averaged or system averaged as well as reverse engineered exchange holes. In the present attempt, the screened range-separated hybrid functional scheme has been applied to the meta-GGA rung ...
