A multi‐trait evaluation of patterns and fitness consequences of breeding phenology plasticity with nocturnal warming and food restriction in a lizard

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Faced with climate warming, ectothermic species shift their breeding phenology, which is in part attributed to an acceleration of gestation or incubation in warmer environments.

Stress hormone rapidly tunes synaptic NMDA receptor through membrane dynamics and mineralocorticoid signalling

open access: yesScientific Reports, 2017
Stress hormones, such as corticosteroids, modulate the transmission of hippocampal glutamatergic synapses and NMDA receptor (NMDAR)-dependent synaptic plasticity, favouring salient behavioural responses to the environment.

TSP50 in Neural Stem Cells Regulates Aging‐Related Cognitive Decline and Neuroinflammation by Altering the Gut Microbiota

open access: yesAging Cell, EarlyView.
TSP50 expression declines in the hippocampus of aged humans and mice. TSP50 deficiency in NSCs accelerates mouse aging, causing cognitive impairments and neuroinflammation. Restoring gut microbiota via FMT and TSP50 overexpression alleviates these phenotypes. Our study shows TSP50's critical role in aging and gut microbiota as a key mediator.

A model of ethanol self‐administration in head‐fixed mice

open access: yesAlcohol, Clinical and Experimental Research, EarlyView.
Advances in neuroscience allow unparalleled access to the brain through multiphoton microscopy, high‐density electrodes, and widefield imaging; however, these techniques often require head fixation. Here, we show head‐fixed mice learn to self‐administer alcohol, extinguish lever‐press responding, and reinstate alcohol seeking to both alcohol and an ...

Associations of plasma sex‐related hormone and protein levels and alcohol dependence

open access: yesAddiction, EarlyView.
Abstract Background and Aims Sex‐related hormones and proteins may underlie sex differences in alcohol use disorder characteristics and consequences. Previous reports suggest steroid sex hormones may influence alcohol consumption behaviors while proteins that regulate their circulation levels are rarely investigated.

The Protective Effects of Polygala tenuifolia and Tenuifolin on Corticosterone-Evoked Ferroptosis, Oxidative Stress, and Neuroinflammation: Insights from Molecular Dynamics Simulations and In Vitro Experiments

open access: yesFoods
Excessive stress is a well-established contributor to neurological damage, insomnia, and depression, imposing a significant burden on individuals and society. This underscores the urgent need for effective stress-relief strategies.

Inhibitory Effect of NMDA Receptors in the Ventral Tegmental Area on Hormonal and Eating Behavior Responses to Stress in Rats

open access: yesBehavioural Neurology, 2014
Background. Stress and its consequences are among the causes of accidents. Objective. The effects of intraventral tegmental area (I-VTA) memantine on the plasma corticosterone and eating parameters disturbance induced by acute stress were investigated ...
