The transcriptional cofactor p300 has histone acetyltransferase activity (HAT) and has been reported to participate in chromatin remodeling and DNA repair. We hypothesized that targeting p300 can enhance the cytotoxicity of gemcitabine, which induces pancreatic cancer cell apoptosis by damaging DNA. Expression of p300 was confirmed in pancreatic cancer cell lines and human pancreatic adenocarci...

Cyclic adenosine monophosphate response element binding (CREB)-binding protein (CBP) and p300 are multidomain transcriptional coactivators that help assemble large regulatory complexes at sites of active transcription. Nullizygosity of CBP or p300 results in pervasive defects in hematopoiesis. To systematically assess the structural domains of p300 required for normal hematopoiesis, we used rec...

Depletion of abiotic resources is a much disputed impact category in life cycle assessment (LCA). The reason is that the problem can be defined in different ways. Furthermore, within a specified problem definition, many choices can still be made regarding which parameters to include in the characterization model and which data to use. This article gives an overview of the problem definition and...

BACKGROUND Steady-state visual-evoked potential (SSVEP)-based brain-computer interfaces (BCIs) generate weak SSVEP with a monitor and cannot use harmonic frequencies, whereas P300-based BCIs need multiple stimulation sequences. These issues can decrease the information transfer rate (ITR). NEW METHOD In this paper, we introduce a novel hybrid SSVEP-P300 speller that generates dual-frequency S...

مقدمه: به منظور کسب آگاهی از فرایند عملکرد قشری، پتانسیل های وابسته به رخداد، بسیار مناسب هستند. از فاکتورهای تأثیرگذار بر p300، جایگاه الکترودی می باشد. پژوهش حاضر به منظور مقایسه دامنه و زمان نهفتگی پتانسیل وابسته به رخداد p300 شنوایی در جایگاه های الکترودی مختلف در افراد هنجار در محدوده سنی 50-18 سال انجام شده است. مواد و روش ها: در این پژوهش مقطعی و غیر مداخله ای،p300 شنوایی به روش تحریک مت...

Background: Robot-assisted lower limb rehabilitation training in early stage could improve the limb function among hemiplegic patients caused by ischemic stroke. P300 potential changes have importantly clinical value for evaluating the improvement in nerve function during the training as one of the objective targets. Methods: Sixty hemiplegic patients after stroke were randomly divided into a L...

BACKGROUND Event-related potential studies show reduced P300 amplitudes in alcohol use disorders (AUDs). Alcohol exposure, genetic vulnerability to alcoholism, and comorbid psychopathology may contribute to this reduction. Most previous research has studied treated adult AUD samples, which have more severe alcoholism, a greater family history of AUDs, and more comorbidity than untreated samples...
