Positive affect is associated with alleviating mental and physiological stress responses. As laughter is a common physiological operationalization of positive affect, we investigated whether the effects of experiencing a stressful event on stress symptoms is lessened by frequency and intensity of daily laughter. Using an intensive longitudinal design, we ambulatory assessed the self-reported experience of stressful events, stress symptoms and the frequency as well as the intensity of laughter in university students' daily lives. Our hierarchical ecological momentary assessment data were analyzed with multilevel models. The results support the stress-buffering model of positive affect: We found that the frequency of laughter attenuated the association between stressful events and subsequent stress symptoms. The level of intensity of laughter, however, was found to have no significant effect. Future studies should use additional psychophysiological indicators of stress and straighten out the differential contributions of frequency and intensity of daily laughter.

Background: Burns in children are often complex injuries, leading to prolonged length of stay (LOS) and significant morbidity. LOS in pediatric intensive care units (PICUs) is a key measure for evaluating illness severity, clinical outcomes, and quality of care. Accurate prediction of LOS is vital for improving care planning and resource allocation.

Objective: Despite the popular public perception that cannabis use may be beneficial for relieving mental health symptoms, the empirical evidence remains equivocal. Various legal hurdles limit the ability to research whether acute high-potency cannabis use affects mental health-related processes. Therefore, the current study used a novel methodology to examine the acute effects of high-potency cannabis flower on emotion regulation.

Introduction: Citri Reticulatae Pericarpium (CRP), also known as Chenpi in Chinese, is the dry mature peel of Citrus reticulata Blanco or its cultivated varieties. CRP as the health-care food and dietary supplement has been widely used in various diseases. The quality of CRP can be affected by various factors, which are closely related to the metabolite composition of CRP.

Leaf angle is a major agronomic trait that determines plant architecture, which directly affects rice planting density, photosynthetic efficiency, and yield. The plant phytohormones brassinosteroids (BRs) and the MAPK signaling cascade are known to play crucial roles in regulating the leaf angle, but the underlying molecular mechanisms are not fully understood. Here, we report a rice WRKY family transcription factor gene, OsWRKY72, which positively regulates leaf angle by affecting lamina joint development and BR signaling.
