A systematic look at a childhood tumor Neuroblastomas—the most common type in infants—develop from fetal nerve cells, and their clinical course is highly variable. Some neuroblastomas are fatal despite treatment, whereas others respond well to treatment some undergo spontaneous regression without treatment. Ackermann et al. sequenced more than 400 pretreatment identified molecular features that characterize the three distinct outcomes. Low-risk tumors lack telomere maintenance mechanisms,...

Neuroblastoma is an embryonal malignancy of the sympathetic nervous system. Spontaneous regression and differentiation neuroblastoma observed in a subset patients, has been suggested to represent delayed activation physiologic molecular programs fetal neuroblasts. Homeobox genes constitute important family transcription factors, which play fundamental role morphogenesis cell during embryogenesis. In this study, we demonstrate that expression majority human HOX class I homeobox significantly...

Sleep and memory are stable heritable traits that strongly differ between individuals. benefits consolidation, the amount of slow wave sleep, sleep spindles, rapid eye movement have been repeatedly identified as reliable predictors for declarative and/or emotional memories retrieved after a consolidation period filled with sleep. These studies typically encompass small sample sizes, increasing probability overestimating real association strength. In large we tested whether individual...

Abstract Background Genomic alterations of the anaplastic lymphoma kinase gene ( ALK ) occur recurrently in neuroblastoma, a pediatric malignancy sympathetic nervous system. However, information on their development over time has remained sparse. Methods were assessed neuroblastomas at diagnosis and/or relapse from total 943 patients, covering all stages disease. Longitudinal diagnostic and relapsed samples individual patients was available 101 102 cases for mutation amplification status,...

Working memory, the capacity of actively maintaining task-relevant information during a cognitive task, is heritable trait. memory deficits are characteristic for many psychiatric disorders. We performed genome-wide gene set enrichment analyses in multiple independent data sets young and aged cognitively healthy subjects (n = 2,824) large schizophrenia case-control sample 32,143). The voltage-gated cation channel activity set, consisting genes related to neuronal excitability, was robustly...

Abstract Sleep is vital for human health and wellbeing, sleep disturbances are comorbid to many mental physiological disorders. Music consistently improves subjective quality, whereas results objective parameters diverge. These inconsistencies might be due inter-individual differences. Here, 27 female subjects listened either music or a control text before 90 minutes nap in within-subjects design. We show that improved quality as compared the condition. In all participants, resulted reduced...

High-risk neuroblastoma remains a therapeutic challenge for pediatric oncologists. The Polo-like kinase 1 (PLK1) is highly expressed in many human cancers and target of the novel small-molecule inhibitor BI 2536, which has shown promising anticancer activity adult malignancies. Here, we investigated effect 2536 on cells vitro vivo to explore PLK1 as potential high-risk therapy.PLK1 transcript levels were analyzed by microarrays 476 primary specimens, correlation with prognostic markers...

Strong memory of a traumatic event is thought to contribute the development and symptoms posttraumatic stress disorder (PTSD). Therefore, genetic predisposition build strong memories could lead increased risk for PTSD after event. Here we show that variability gene encoding PKCα ( PRKCA ) was associated with capacity—including aversive memory—in nontraumatized subjects European descent. This finding replicated in an independent sample subjects, who additionally underwent functional magnetic...

Extensive evidence indicates that women outperform men in episodic memory tasks. Furthermore, are known to evaluate emotional stimuli as more arousing than men. Because arousal typically increases formation, the females' advantage might be pronounced for emotionally information neutral information.

Neuroblastoma is an embryonal pediatric tumor that originates from the developing sympathetic nervous system and shows a broad range of clinical behavior, ranging fatal progression to differentiation into benign ganglioneuroma. In experimental neuroblastoma systems, retinoic acid (RA) effectively induces neuronal differentiation, RA treatment has been therefore integrated in current therapies. However, molecular mechanisms underlying are still poorly understood. We here investigated role...

OBJECTIVE: In an emergency department, discharge communication represents a key step in medical care. The efficiency of this doctor-patient interaction could be hampered by two bounds: limited time care and patients’ mind’s capacity to encode, store maintain information. Such limitations are the focus study. Specifically, we examine number items physicians deem crucial necessary estimated present them.
