Do NMDA receptor kinetics regulate the end of critical periods of plasticity?

Published: November 2001

Increasing NR2A subunit expression and the associated shortening of the NMDA-EPSC are thought to underlie the loss of diverse types of sensory cortical plasticity. Lu and colleagues (Lu et al., 2001 [this issue of Neuron]) now report that mice lacking the NR2A subunit display normal duration of critical periods of barrel cortex plasticity. Shortening of the NMDA-EPSC is therefore not responsible for the end of these critical periods.

Temporal dynamics of PM induced cell death: Emphasizing inflammation as key mediator in the late stages of prolonged myocardial toxicity.

Multiple forms of cell death contribute significantly to cardiovascular pathologies, negatively impacting cardiac remodeling and leading to heart failure. While myocardial cell death has been associated with PM induced cardiotoxicity, the temporal dynamics of various cell death forms, such as apoptosis, ferroptosis, necroptosis, and pyroptosis, in relation to inflammatory processes, remain underexplored. This study examines the time-dependent onset and progression of these cell death pathways in the myocardium and their correlation with inflammation in a Wistar rat model.

This pilot-scale study investigated nitrifying moving bed biofilm reactors (MBBRs) in a post-lagoon treatment setup over two years to evaluate the impact of seasonal ammonia fluctuations on winter nitrification. In Year 2, reactors without fall ammonia starvation achieved significantly higher winter ammonia removal (97.2 ± 1.

Introduction: Removing uremic toxins from the body is one of the most critical points in the maintenance hemodialysis (MHD) population. This study aimed to evaluate the effects of medium cutoff (MCO) membranes on pulse wave velocity (PWV) and augmentation index (AIx), early markers of arterial stiffness, in MHD patients over both short- and long-term periods.

Methods: Twenty MHD patients were included in this study.

Objectives: Hypoglossal nerve stimulation (HGNS) is a promising surgical option for patients with obstructive sleep apnea (OSA) who are intolerant of continuous positive airway pressure therapy (CPAP). Efficacy studies for HGNS stimulation largely focus on the apnea-hypopnea index and/or oxygen desaturation index. This study's objective was to show the physiological effects of HGNS stimulation on upper airway patency, airflow, and treatment effect during polysomnography (PSG) testing.

Background: Since the onset of the COVID-19 pandemic, the scientific community has been concerned about the high rates of psychological distress among adolescents. The pandemic not only tested adolescents' adaptation, but also disrupted key areas of their development. This demonstrates the need to study their psychological adjustment over time during this critical period to better guide services.
