The Role of Gender in the Relationship Between Reinforcement Sensitivity and Aggression among Adolescents [PDF]

International Journal of Emotional Education, 2020
This study focuses on the relationship between reinforcement sensitivity and aggression according to the combination of forms and functions of aggression (i.e.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Neural correlates of reward and loss sensitivity in psychopathy [PDF]

Social Cognitive and Affective Neuroscience, 2013
Psychopathy is a personality disorder associated with callous and impulsive behavior and criminal recidivism. It has long been theorized that psychopaths have deficits in processing reward and punishment. Here, we use structural and functional magnetic resonance imaging to examine the neural correlates of reward and loss sensitivity in a group of ...

Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Reward dysregulation following early-life adversity: pathways to externalising behaviours

Journal of Affective Disorders Reports
Early-life adversity (ELA) has long-lasting effects on mental health by disrupting the neurodevelopment of key pathways, including reward-related circuitry.

At what stage of neural processing does cocaine act to boost pursuit of rewards? [PDF]

PLoS ONE, 2010
Dopamine-containing neurons have been implicated in reward and decision making. One element of the supporting evidence is that cocaine, like other drugs that increase dopaminergic neurotransmission, powerfully potentiates reward seeking.

Investigating the relationship between reward sensitivity, impulsivity, and food addiction: A systematic review

, 2020
Objective: The aim of the current research was to identify the extent to which reward sensitivity and impulsivity were related to food addiction. Method: Forty-five studies, published from 2009 to June 2019, investigating reward sensitivity and/or ...

Dopamine restores reward prediction errors in old age [PDF]

, 2013
Senescence affects the ability to utilize information about the likelihood of rewards for optimal decision-making. Using functional magnetic resonance imaging in humans, we found that healthy older adults had an abnormal signature of expected value ...

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an
