P300 in schizophrenia: Then and now

Biological Psychology
The 1965 discovery of the P300 component of the electroencephalography (EEG)-based event-related potential (ERP), along with the subsequent identification of its alteration in people with schizophrenia, initiated over 50 years of P300 research in schizophrenia.

Effects of Sleep Deprivation on Visual P300 [PDF]

, 2006
睡眠剥夺在日常生活工作中广泛存在,导致认知功能下降,其中警觉水平下降最为明显。实验采用Oddball范式辨别任务,研究了32名青年男性在不同睡眠剥夺条件(sleep deprivation,SD)下(SD21h、SD45h、SD69h、正常对照组)的事件相关电位(event-related potentials,ERPs)P300成分的变化。结果表明,随SD时间延长,P300波幅降低、潜伏期延长 ...

A comparison of cognitive functions in non-hypoxemic chronic obstructive pulmonary disease (COPD) patients and age-matched healthy volunteers using mini-mental state examination questionnaire and event-related potential, P300 analysis

Lung India, 2013
Objective: To assess sub-clinical cognitive dysfunctions in stable chronic obstructive pulmonary disease (COPD) patients having no hypoxemia vs. age-matched healthy volunteers using (i) an electrophysiological test: Auditory event related potential, P300

Cigarette smoke extract induces the senescence of endothelial progenitor cells by upregulating p300

Tobacco Induced Diseases, 2023
Introduction Endothelial progenitor cells (EPCs) are the main source of endothelial cells. The senescence of EPCs is involved in the pathogenesis of chronic obstructive pulmonary disease (COPD).

Combined frontal and parietal P300 amplitudes indicate compensated cognitive processing across the lifespan

Frontiers in Aging Neuroscience, 2014
In the present study the frontal and parietal P300, elicited in an auditory oddball paradigm were investigated in a large sample of healthy participants (N=1,572), aged 6-87.

Suppressing Unwanted Autobiographical Memories Reduces Their Automatic Influences: Evidence from Electrophysiology and an Implicit Autobiographical Memory Test [PDF]

, 2015
The present study investigated the extent to which people can suppress unwanted autobiographical memories in a mock crime memory detection context. Participants encoded sensorimotor-rich memories by enacting a lab crime (stealing a ring) and received ...

Mutant and Wild-Type Tumor Suppressor p53 Induces p300 Autoacetylation

iScience, 2018
Summary: The transcriptional co-activator p300 is essential for p53 transactivation, although its precise role remains unclear. We report that p53 activates the acetyltransferase activity of p300 through the enhancement of p300 autoacetylation ...

USP24-dependent stabilization of Runx2 recruits a p300/NCOA3 complex to transactivate ADAMTS genes and promote degeneration of intervertebral disc in chronic inflammation mice

Biology Direct, 2023
Background Intervertebral disc degeneration (IDD) naturally occurs during the aging process. Its occurrence is closely related to chronic inflammation; however, the causal relationship between them is controversial.

Gender effects on auditory P300: A systematic review

, 2018
The evidence suggests that gender-related effects could influence the electrophysiological P300 parameters and stand as an additional source of variation for both clinical and non-clinical subjects. The aim of this paper is to characterize gender-related

Targeting transcription factors associated with hemoglobinopathies: Lessons from successful interventions and implications for cancer

Molecular Oncology, EarlyView.
This review summarizes the transcription factors, repressive chromatin‐modifying complexes, and epigenetic mechanisms that control fetal hemoglobin repression. Notably, many regulators of γ‐globin silencing also function in transcriptional and epigenetic networks that drive cancer, highlighting opportunities to translate advances in hemoglobinopathy ...
