Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Motivational salience modulates early visual cortex responses across task sets [PDF]

, 2017
Motivationally relevant stimuli benefit from strengthened sensory processing. It is unclear, however, if motivational value of positive and negative valence has similar or dissociable effects on early visual processing. Moreover, whether these perceptual

EP300 Modulates MCM8 Transcription and Augments the Malignant Phenotype of Hepatitis B Virus–Positive Hepatocellular Carcinoma Cells

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Chronic infection with the hepatitis B virus (HBV) remains one of the primary drivers of the development of hepatocellular carcinoma (HCC), a highly aggressive malignancy with a grim prognosis. This study focused on the role of E1A‐binding protein p300 (EP300) in the malignant phenotype of HBV‐positive HCC cells and its functional mechanism ...

Engineering study on the use of Head-Mounted display for Brain- Computer Interface [PDF]

arXiv, 2019
In this article, we explore the availability of head-mounted display (HMD) devices which can be coupled in a seamless way with P300-based brain-computer interfaces (BCI) using electroencephalography (EEG). The P300 is an event-related potential appearing about 300ms after the onset of a stimulation.

The Neurometric Correlates of Trauma Using the Brief Neurometric Battery (BNB) [PDF]

, 2017
Objective: The goal of this research was to determine the utility of a novel Brief Neurometric Battery (BNB) (Kieffaber et al., 2016) for measuring the neurometric correlates of a) experiences with sexual trauma and b) personality characteristics, and to

Memory recall in arousing situations – an emotional von Restorff effect? [PDF]

, 2006
BACKGROUND: Previous research has demonstrated a relationship between memory recall and P300 amplitude in list learning tasks, but the variables mediating this P300-recall relationship are not well understood. In the present study, subjects were required

Key Regulators of Parasite Biology Viewed Through a Post‐Translational Modification Repertoire

PROTEOMICS, EarlyView.
ABSTRACT Parasites are the leading causes of morbidity and mortality in both humans and animals, imposing substantial socioeconomic burdens worldwide. Controlling parasitic diseases has become one of the key issues in achieving “One Health”. Most parasites have sophisticated life cycles exhibiting progressive developmental stages, morphologies, and ...

A toolbox for decoding BCI commands based on event-related potentials

Frontiers in Human Neuroscience
Commands in brain-computer interface (BCI) applications often rely on the decoding of event-related potentials (ERP). For instance, the P300 potential is frequently used as a marker of attention to an oddball event.

Adaptive Stimulus Selection in ERP-Based Brain-Computer Interfaces by Maximizing Expected Discrimination Gain [PDF]

arXiv, 2017
Brain-computer interfaces (BCIs) can provide an alternative means of communication for individuals with severe neuromuscular limitations. The P300-based BCI speller relies on eliciting and detecting transient event-related potentials (ERPs) in electroencephalography (EEG) data, in response to a user attending to rarely occurring target stimuli amongst ...

Biomarkers of cognitive impairment in obstructive sleep apnea

Sleep Research, EarlyView.
Abstract Mild cognitive impairment (MCI) associated with obstructive sleep apnea (OSA) has garnered widespread attention. The mechanisms underlying MCI in patients with OSA are currently believed to be the combined effects of nocturnal intermittent hypoxia, hypercapnia, and sleep fragmentation, all of which can impact cerebral blood flow, synaptic ...
