Descriptive Linear modeling of steady-state visual evoked response

A study is being conducted to explore use of the steady state visual-evoke electrocortical response as an indicator of cognitive task loading. Application of linear descriptive modeling to steady state Visual Evoked Response (VER) data is summarized. Two aspects of linear modeling are reviewed: (1) unwrapping the phase-shift portion of the frequency response, and (2) parsimonious characterization of task-loading effects in terms of changes in model parameters. Model-based phase unwrapping appears to be most reliable in applications, such as manual control, where theoretical models are available. Linear descriptive modeling of the VER has not yet been shown to provide consistent and readily interpretable results

New waterboatmen records for Western Canada (Hemiptera: Corixidae)

Trichocorixa verticalis (Fieber) is reported for the first time from the mainland of British Columbia and the subspecific assignment is discussed. Based on specimens in the Spencer Entomological Museum, one provincial record and one territorial record are added to the recent checklist of Canadian Hemiptera

Os espíritos imundos nos sinóticos e o Mito dos Vigilantes

A obra compósita conhecida como 1 Enoque, formada por cinco livros, logrou muita importância no(s) Judaísmo(s) do segundo templo, como também no(s) Cristianismo(s) dos primeiros quatro séculos. Por isso, a intenção deste trabalho é testar a contribuição do Mito dos Vigilantes (1 Enoque 6-11) para o imaginário do demoníaco nos sinóticos, em especial enquanto espírito imundo. Com o acúmulo de imagens dos seres malignos no período do segundo templo e a sua próxima relação com o Mito dos Vigilantes, concluímos ser possível a hipótese de que o demoníaco ao ser chamado de espírito impuro no Novo Testamento trás indícios e ecos do desenvolvimento, nas tradições de Enoque e na apocalíptica, do Mito dos Vigilantes.

Analytical comparison of transient and steady state visual evoked cortical potentials

To better describe the linear-dynamic properties of the human visual-cortical response system, transient and steady state Visual Evoked Response Potentials (VERP) were observed. The stimulus presentation device provided both the evoking stimulus (flickering or pulsing lights) and a video task display. The steady state stimulus was modulated by a complex, ten frequency, sum-of-sines, wave. The transient VERP was the time-locked average of the EEG to a series of narrow light pulses (pulse width of 10 msec). The Fourier transform of the averaged pulses had properties that approximate band limited white noise, i.e., a flat spectrum over the frequency region spanned by the 10 summed sines. The Fourier transform of both the steady state and the transient evoked potentials resulted in transfer that are equivalent and therefore comparable. To investigate the effects of task loading on evoked potentials, a grammatical reasoning task was provided. Results support the relevancy of continued application of a systems engineering approach for describing neurosensory functioning

Parenting the Premature Infant: Potential Iatrogenesis from the Neonatal Intensive Care Experience

(1) Developmental outcomes of premature infants are associated with the quality of the home environment and the level of parenting skills the family possesses. Successful development of the parenting role may be negatively influenced by the Neonatal Intensive Care Unit (NICU) environment and nursing practices. Identification of interventions that promote the development of parenting skills in the NICU can potentially improve developmental outcomes for premature infants.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/73814/1/j.1524-475X.1996.00046.x.pd

Proteomic Analysis Identifies NDUFS1 and ATP5O as Novel Markers for Survival Outcome in Prostate Cancer

Simple Summary Due to the heterogeneity of prostate cancer (PCa), it is still difficult to provide risk stratification. Metabolic changes in PCa tissue have been described during tumor progression at genetic and transcriptomic level, but these have not yet clearly contributed to improved diagnosis and therapy. The aim of our study was to identify novel markers for aggressive prostate cancer in a proteomics-derived dataset by immunohistochemical analysis and correlation with transcriptomic data. Here, we provide potential new markers-NDUFS1 and ATP5O-for risk stratification in PCa. Additionally, we reveal for the first time a concordant increase of NDUFS1/ATP5O of mRNA expression in transcriptomic datasets and at protein level. We aimed to identify novel markers for aggressive prostate cancer in a STAT3-low proteomics-derived dataset of mitochondrial proteins by immunohistochemical analysis and correlation with transcriptomic data and biochemical recurrence in a STAT3 independent PCa cohort. Formalin-fixed paraffin-embedded tissue (FFPE) sample selection for proteomic analysis and tissue-microarray (TMA) generation was conducted from a cohort of PCa patients. Retrospective data analysis was performed with the same cohort. 153 proteins differentially expressed between STAT3-low and STAT3-high samples were identified. Out of these, 46 proteins were associated with mitochondrial processes including oxidative phosphorylation (OXPHOS), and 45 proteins were upregulated, including NDUFS1/ATP5O. In a STAT3 independent PCa cohort, high expression of NDUFS1/ATP5O was confirmed by immunocytochemistry (IHC) and was significantly associated with earlier biochemical recurrence (BCR). mRNA expression levels for these two genes were significantly higher in intra-epithelial neoplasia and in PCa compared to benign prostate glands. NDUFS1/ATP5O levels are increased both at the mRNA and protein level in aggressive PCa. Our results provide evidence that NDUFS1/ATP5O could be used to identify high-risk PCa patients
