Pediatric Blood &Cancer, EarlyView.ABSTRACT Results of COG ANBL1221 changed treatment paradigms for patients with relapsed/refractory neuroblastoma. Chemoimmunotherapy with irinotecan/temozolomide/dinutuximab is now used as both bridge therapy following suboptimal response to induction and as treatment in first relapse.

Pediatric Blood &Cancer, EarlyView.ABSTRACT A lethal round‐cell malignancy with an MN1::ZNF341 fusion has recently been reported in three infants. Here, we describe four further tumors, three in newborns (including monozygotic twins), and one in an adolescent. Detailed clinical, radiological, and histopathological data differentiate these tumors from their main mimics, neuroblastoma and

Impact of Metastatic Patterns on Survival and Response to Therapy in Neuroblastoma
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background While the presence of metastases in neuroblastoma (NB) is a well‐established prognostic factor, the clinical significance of dissemination patterns and tumour burden and their impact on response and survival remains poorly understood.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Embryonal tumors comprise the majority of malignant central nervous system (CNS) neoplasms diagnosed in children under 3 years of age. Compared with their counterparts in older children, these tumors exhibit distinct molecular biology and a more aggressive clinical phenotype, while their management is complicated by the heightened ...

Active Comb Filter Using Operational Transconductance Amplifier
Active and Passive Electronic Components, 2014 A new approach for the design of an active comb filter is proposed to remove the selected frequencies of various signals. The proposed filter is based on only OTAs and capacitors, hence suitable for monolithic integrated circuit implementation.

Operational Transresistance Amplifier-Based Multiphase Sinusoidal Oscillators
Journal of Electrical and Computer Engineering, 2011 Multiphase sinusoidal oscillator circuits are presented which utilize Operational Transresistance Amplifier (OTRA) as the active element. The first circuit produces n odd-phase oscillations of equal amplitudes and equally spaced in phase.
