..SIGNIFICANCE STATEMENT Astrocytes play important roles in synaptic transmission by extending fine processes around synapses. In this study, we showed that a single exposure to an acute stress triggered a retraction of lateral/fine processes in mouse cerebellar astrocytes. These astrocytes express GluA1, a glutamate receptor subunit known to lengthen astrocyte processes. We showed that astrocytic structural changes are associated with a reduction of GluA1 protein … Continue reading Emotional #Stress Induces Structural Plasticity in Bergmann Glial Cells via an AC5–CPEB3–GluA1 Pathway
Stress alters brain function by modifying the structure and function of neurons and astrocytes. The fine processes of astrocytes are critical for the clearance of neurotransmitters during synaptic transmission. Thus, experience-dependent remodeling of glial processes is anticipated to alter the output of neural circuits.. ..Significance statement Astrocytes play important roles in synaptic transmission by extending fine processes around synapses. In this study, we showed that … Continue reading Emotional #stress induces structural #plasticity in Bergmann glial cells via an AC5-CPEB3-GluA1 pathway
We examined how proactive coping and daily mindfulness may work together to predict emotional reactivity to daily stressors. Using data from the Mindfulness and Anticipatory Coping Everyday study (MACE; Neupert & Bellingtier, 2017; Neupert & Bellingtier, 2019), 116 older adults and 107 younger adults participated in a daily diary study for nine consecutive days. Results from multilevel models suggest that people high in proactive coping … Continue reading Thinking ahead and staying in the present: Implications for reactivity to daily stressors
Chronic occupational #stress is common among health care practitioners, with potential impacts on personal mental health and staff turnover. This study investigated whether directing practitioners’ attention to #thankful events in work could reduce stress and depressive symptoms ..One hundred two practitioners were randomly assigned into 3 conditions: gratitude, hassle, and nil-treatment. Those with scheduled long leaves were excluded. Participants in the gratitude and hassle group … Continue reading Improving mental health in health care practitioners: Randomized controlled trial of a gratitude intervention.
The aim of the present study was to determine the effect of different nap opportunity durations on short-term maximal performance, attention, feelings, muscle soreness, fatigue, stress and sleep. Twenty physically active men (age: 21.1 ± 3.6 years, height: 176.4 ± 5.7 cm, body-mass: 72 ± 10.8 kg) performed the 5-jump and the digit-cancellation (i.e., attention) tests after four randomized nap opportunity conditions: no-nap opportunity (N0), 25 min of nap opportunity (N25), 35 min of nap opportunity … Continue reading Effect of different #nap opportunity durations on short-term maximal performance, attention, feelings, muscle soreness, fatigue, #stress and sleep.
..144 919 individuals with stress related disorders (post-traumatic stress disorder (PTSD), acute stress reaction, adjustment disorder, and other stress reactions) identified from 1987 to 2013 ..Stress related disorders were associated with all studied life threatening infections, with the highest relative risk observed for meningitis (sibling based analysis 1.63 (1.23 to 2.16)) and endocarditis (1.57 (1.08 to 2.30)). Younger age at diagnosis of a stress related disorder … Continue reading Stress related disorders and subsequent risk of life threatening #infections: population based sibling controlled cohort study
This study investigated the link between experience of daily stress, depression symptoms, and the Facebook Addiction Disorder (FAD) in Germany and in the United States. In samples from both countries (German sample: N = 531; U.S. sample: N = 909), daily stress was positively associated with FAD. Depression symptoms significantly positively moderated this positive relationship. Thus, current findings demonstrate that depressed individuals who often tend to intensively use Facebook … Continue reading Relationship Between Daily #Stress, #Depression Symptoms, and #Facebook Addiction Disorder in Germany and in the United States
