Event-Related Brain Potentials in Psychopathology: Clinical and cognitive perspectives

open access: yesPsychologica Belgica, 2006
Since the discovery of the P300 component, a large number of studies have been conducted with the aim to find abnormalities of this psychophysiological marker among the main psychiatric disorders.

Effects of age on the P300 component of the event-related potential from auditory stimuli: peak definition, variation, and measurement. [PDF]

open access: yes, 1985
An auditory "oddball" paradigm was used to elicit the P300 component of the event-related brain potential (ERP) from a large sample of young (5 to 15 years) and older (20 to 86 years) persons.

P300 component identification using source analysis techniques:Reduced latency variability

open access: yes, 2003
P300 latency variability in normal subjects is a complicating factor in clinical event-related potential studies because it limits diagnostic applicability.

A study of cognitive assessment in Type 2 diabetes mellitus patients

open access: yesNational Journal of Physiology, Pharmacy and Pharmacology, 2019
Background: Studying the deleterious effects of Type 2 diabetes mellitus (T2DM) on cognition is gaining a lot of attention. Cognition is measured by the P300 component of event-related potentials (ERPs). Hence, we studied P300 in T2DM.

Role of the unique N-terminal domain of CtBP2 in determining the subcellular localisation of CtBP family proteins [PDF]

open access: yes, 2006
BACKGROUND: CtBP1 and CtBP2 are transcriptional co-repressors that modulate the activity of a large number of transcriptional repressors via the recruitment of chromatin modifiers.

Quantum‐Level Influences on Enzyme Reactions and Their Ripple Effects on Biological Phenomena

open access: yesAdvanced Physics Research, EarlyView.
Because living organisms are ultimately composed of atoms and molecules, quantum‐mechanical effects are expected to contribute to biological phenomena. Quantum biology seeks to elucidate life processes from a quantum‐mechanical perspective. This review discusses how quantum‐level effects, including quantum tunneling, may propagate from enzymatic proton‐

Identification of adenovirus E1A gene regions involved in chemosensitisation of prostate cancer cells [PDF]

open access: yes, 2009
PhDReplication-selective adenoviruses are promising anti-cancer therapies (virotherapy). Viruses can be engineered to selectively target cancer cells by deleting viral genes involved in cell cycle regulation.

De Novo Design of Multivalent α/β‐Peptides Mimicking Transcription Factors Targeting the CBP KIX Domain

open access: yesChemistry – A European Journal, EarlyView.
A modular, de novo α/β‐peptide design strategy allows fine‐tuning of ligand properties, resulting in multivalent ligands that simultaneously target separate binding sites on the protein surface. ABSTRACT Protein‐protein interactions that regulate gene expression in the nucleus are increasingly recognized as potential therapeutic targets but present ...

Revisiting the Model Human Processor: a neurophysiological investigation based on P300 and Bereitschaftspotential

open access: yesFrontiers in Human Neuroscience
IntroductionThe Model Human Processor (MHP), while useful, lacks direct neurophysiological validation. This study aimed to validate and extend the MHP by analyzing P300 and Bereitschaftspotential (BP) brainwave components.MethodsOur initial finding of ...
