Persistently increased post-stress activity of paraventricular thalamic neurons is essential for the emergence of stress-induced alterations in behaviour.

A single exposure to a stressful event can result in enduring changes in behaviour. Long-term modifications in neuronal networks induced by stress are well explored but the initial steps leading to these alterations remain incompletely understood. In this study, we found that acute stress exposure triggers an immediate increase in the firing activity of calretinin-positive neurons in the paraventricular thalamic nucleus (PVT/CR+) that persists for several days in mice.

Dual role of vascular endothelial growth factor-C in post-stroke recovery.

Cerebrospinal fluid (CSF), antigens, and antigen-presenting cells drain from the central nervous system (CNS) into lymphatic vessels near the cribriform plate and dura, yet the role of these vessels during stroke is unclear. Using a mouse model of ischemic stroke, transient middle cerebral artery occlusion (tMCAO), we demonstrate stroke-induced lymphangiogenesis near the cribriform plate, peaking at day 7 and regressing by day 14. Lymphangiogenesis is restricted to the cribriform plate and deep cervical lymph nodes and is regulated by VEGF-C/VEGFR-3 signaling.

Comparative study of quantitative identification methods for peri-urban areas based on a multi-indicator system.

As peri-urbanisation becomes widespread, quantitative methods for identifying peri-urban areas (PUAs) are increasingly abundant. This study aims to quantitatively compare the differences in the results obtained from multiple PUA identification methods within the same study area and to analyse the spatial patterns of the PUAs. The Threshold Method, Breakpoint Clustering, and Multilayer Perceptron were chosen to compare the identification results of PUAs in Zhengzhou City, China.

Sex Differences in the Neuroendocrine Stress Response: A View from a CRH-Reporting Mouse Line.

Corticotropin-releasing hormone (CRH) neurons within the paraventricular hypothalamic nucleus (PVH) play a crucial role in initiating the neuroendocrine response to stress and are also pivotal in coordination of autonomic, metabolic, and behavioral stress reactions. Although the role of parvocellular CRH neurons in activation of the hypothalamic-pituitary-adrenal (HPA) axis is well established, the distribution and function of CRH-expressing neurons across the whole central nervous system are less understood. Stress responses activate complex neural networks, which differ depending on the type of stressor and on the sex of the individual.

Exploring Individual Components of Sport Persistence in the Light of Gender, Education, and Level and Type of Sport.

Sport persistence can be coded as an indicator of sport performance and commitment, incorporating personality traits such as resilience, adaptive coping, and positive personality traits. Thus, athletes do not merely persist in sporting activities but are qualitatively committed to them. In the present research, we used a qualitative methodology to investigate the factors underlying sport persistence, using Bronfenbrenner's socio-ecological model.
