neuroblastoma is the most common extracranial solid tumor in children. the co- occurrence of neuroblastoma and acute lymphoblastic leukemia is rare. we report a rare case of advanced-stage neuroblastoma in a 3.5-year-old girl that was accompanied by acute lymphoblastic leukemia following treatment. her leukemia may have been due to chemotherapy (secondary leukemia) or may have been de novo.

A 53-year-old woman developed a de novo aneurysm after contralateral internal carotid artery occlusion, and another 42-year-old woman developed a de novo aneurysm after contralateral vertebral artery occlusion. Both patients experienced a rapid development of de novo aneurysm formation, 6 and 9 months, respectively. The development of de novo aneurysm on the contralateral artery after parent ar...

Prions are responsible for a heterogeneous group of fatal neurodegenerative diseases. They occur in three forms - sporadic, genetic, or acquired - and involve non-covalent post-translational modifications of the cellular prion protein (PrP(C)). Prions (PrP(Sc)) are characterized by their infectious properties and intrinsic ability to act as a template, converting the normal, physiological PrP(C...

Polymorphism data can be used to identify loci at which a beneficial allele has recently gone to fixation, given that an accurate description of the signature of selection is available. In the classical model that is used, a favored allele derives from a single mutational origin. This ignores the fact that beneficial alleles can enter a population recurrently by mutation during the selective ph...

Entry in Telecommunication: Customer Loyalty, Price Sensitivity and Access Prices* The purpose of this article is to investigate the prospects for entry into an existing network in the telecommunication industry, and how public policy may promote a more competitive outcome. We apply a model that captures the fact that the incumbent has an installed base of loyal consumers, that some consumers a...
