Extracellular pectin-RALF phase separation mediates FERONIA global signaling function.

The FERONIA (FER)-LLG1 co-receptor and its peptide ligand RALF regulate myriad processes for plant growth and survival. Focusing on signal-induced cell surface responses, we discovered that intrinsically disordered RALF triggers clustering and endocytosis of its cognate receptors and FER- and LLG1-dependent endocytosis of non-cognate regulators of diverse processes, thus capable of broadly impacting downstream responses. RALF, however, remains extracellular. We demonstrate that RALF binds the cell wall polysaccharide pectin. They phase separate and recruit FER and LLG1 into pectin-RALF-FER-LLG1 condensates to initiate RALF-triggered cell surface responses. We show further that two frequently encountered environmental challenges, elevated salt and temperature, trigger RALF-pectin phase separation, promiscuous receptor clustering and massive endocytosis, and that this process is crucial for recovery from stress-induced growth attenuation. Our results support that RALF-pectin phase separation mediates an exoskeletal mechanism to broadly activate FER-LLG1-dependent cell surface responses to mediate the global role of FER in plant growth and survival.

Mediating effect of intolerance of uncertainty in the relationship between coping styles with stress during pandemic (COVID-19) process and compulsive buying behavior.

Novel CoronaVirus Disease (COVID-19) has begun to expand swiftly beyond all borders and turned into a global source of infection for humans in that all media corporations began to repeatedly share breaking news to release the latest data of all countries. The consequence of that has been a heightened level of anxiety among humans and opting for unorthodox consumption behaviors as consumers. In this study the attempt was to analyze human behaviors during the ongoing pandemic process from the perspective of psychology and marketing fields of science. In so doing, interrelation among anxiety, which surfaced because of Covid-19 pandemic, coping style with stress of individuals and compulsive purchase behavior has been explored. Based on these interrelations, a structural model was suggested. Findings of the research indicated that anxiety has high effect on the helpless approach dimension, which is one of the coping styles with stress; and that helpless approach alone has an effect on compulsive buying behavior. Besides, another objective of the study was to evaluate the mediating effect of intolerance of uncertainty between coping style with stress and compulsive buying behavior. That analysis evidenced that intolerance of uncertainty in such an interrelation had a partial mediating effect.

[General and specific individual post-traumatic stress disorder-related mechanisms among paramedics]. / Specyficzne korelaty i ogólny mechanizm psychologiczny zespolu stresu pourazowego u ratowników medycznych.

BACKGROUND: Due to the nature of their work, paramedics face an increased risk of developing a post-traumatic stress disorder. The main goal of this research project was to point out specific correlates of post-traumatic stress. The authors decided to approach that issue from the perspective of emotional-cognitive deficits and resources, such as alexithymia, rumination and coping with stress. MATERIAL AND METHODS: The authors conducted 3 independent research projects in the first half of the year 2017 in the Wielkopolskie voivodship, that included paramedics. In each one of them, they estimated post-traumatic stress disorder (PTSD) symptoms using The Impact of Event Scale-Revised (IES-R). Additionally, in the first study the authors used alexthymia scale, Polish verion of Toronto Alexithymia Scale-20 (TAS-20), in the second - rumination questionnaire, in the third - coping with stress measured with Inventory for Measuring Coping with Stress Mini-COPE. RESULTS: The analyses demonstrate a relationship between PTSD symptoms and both alexithymia and rumination. There was not any significant relationship between coping strategies and PTSD. The mediation analysis results prove the role of intrusion as a mediator in a relationship between hyperarousal and avoidance. Individuals with PTSD demonstrate high avoidance for situations similar to the original traumatic event because high hyperarousal increases the risk of intrusion. CONCLUSIONS: More than a half of paramedics demonstrated post-traumatic stress symptoms, which most likely is a prognosis factor for future development of PTSD among them. The emotional-cognitive deficits correlated with traumatic stress symptoms. Resources such as coping strategies were not sufficient enough mechanisms for coping with traumatic stress. Post-traumatic stress disorder may be seen as a dynamic sequence. The nature of paramedics work entails the risk for experiencing complex and/or secondary trauma, which represent the phenomena that should be further examined. Med Pr. 2019;70(1):53-66.

Job Stress and Stress Coping Strategy among Workers in A Regional Statistics Office : A Preliminary Study / 정신신체의학

OBJECTIVES: The purpose of this preliminary study was to investigate job stress and stress coping strategy among workers in a regional statistics office. METHODS: A total of 133 workers in regional statistics office participated in this study and they were divided into two groups, survey group(n=109) and support group(n=24) depending on relation to statistical survey task. They were asked to respond to Short Form of Korean Occupational Stress Scale(KOSS-SF) and Stress Coping Strategy(SCS) to investigate sociodemographic characteristics, job stress, and stress coping strategy. RESULTS: The proportion of the 133 participants in the sample was 59(44.4%) of men, 74(55.6%) of women. There were no significant differences in KOSS-SF scores in relation to age, sex, education, and marital status, while the KOSS-SF scores were significantly different between the two groups. In regard to the subscales of KOSS-SF, the two groups had significant differences in insufficient job control, interpersonal conflict, job insecurity, and organization system. In addition, the total score of KOSS-SF had a negative correlation with problem-focused coping strategy and social support coping strategy of SCS. CONCLUSIONS: Our results suggest that workers of survey group had more job stress compared to those who works in support group in regional statistical office. In addition, in comparison with workers of support group, both men and women of survey group get stressed when they were confronted with interpersonal conflicts. Our results suggest that using problem-focused coping and social support coping strategy lowers job stress.

Moderating Effect of Stress Coping Strategies on the Relationship between a National Statistics Office Workers' Occupational Stress and Mental Health / 신경정신의학

OBJECTIVES: This study examined the moderating effects of stress coping strategies on the relationship between occupational stress of national statistical office workers and mental health. METHODS: Subjects were 133 workers at a regional statistics office. Occupational stress, stress coping strategies, and mental health were examined using the Korean Occupational Stress Scale (KOSS), Ways of Coping Checklist, and The Symptom Check-List-90-R. Stress coping strategies were composed of problem-focused coping, social support coping, emotion-focused coping, and wishful thinking coping. RESULTS: Moderated regression indicated that the social support coping and emotion-focused coping style positively moderated the relationship between occupational stress and mental health in national statistical office workers. The social support coping style positively moderated the relationship between interpersonal conflict (KOSS subscale) and mental health in national statistical office workers. The emotion-focused coping style positively moderated the relationship between job insecurity (KOSS subscale) and mental health in national statistical office workers. The emotion-focused coping style negatively moderated the relationship between job demand (KOSS subscale) and mental health in national statistical office workers. CONCLUSION: The implications of this study included that negative results due to high occupational stress can be varied by use of suitable stress coping strategies.

Correlation analysis of hyperarousal, personality characteristics, coping strategy with the vulnerability to stress-related sleep disturbance / 中华行为医学与脑科学杂志

Objective To explore the influence factors of hyperarousal,personality characteristics and coping strategies on the vulnerability to stress-related sleep disturbance.Methods A total of 345 sleep good healthy volunteers were recruited bypurposive sampling technique.Every participant completed an extensive survey that included the general condition questionnaire,Ford Insomnia Response to Stress Test (FIRST),PreSleep Arousal Scale (PSAS),NEO Personality Inventory-Revised (NEOPI-R),Coping Inventory for Stressful Situations (CISS) and Heart Rate Variability(HRV).All participants were classified as High risk group andLow risk group by using the FIRST criterion.Results The high risk group was younger than the low risk group (27.91±8.22 vs 24.82±7.73,P＜0.01),and had a higher percentage of females (34.7％ vs 53.4％,P＜0.05).The high risk group showed significantly higher scores in PSAS total (30.11±6.22),pesleep cognitive arousal (17.73± 4.51),presleep somatic arousal (12.78 ± 3.23),neuroticism (3.13 ± 0.51),emotion oriented (48.98 ± 10.54),but lower score in extraversion (2.96±0.54),then those indicators of the low risk group (28.52±5.82,16.32±4.32,11.41±2.75; 3.11±0.56,2.87±0.47,46.23±11.21,3.11±0.56,P＜0.01 or 0.05).There were significant difference between the two group in LF/HF (1.51 ±0.19 vs 1.17±0.11,P＜0.01),HF((311.21 ±72.32) ms2/Hz vs (490.43 ± 91.74)ms2/Hz,P＜0.01),LF((469.49±85.67)ms2/Hzvs (573.21±98.75) ms2/Hz,P＜0.01) in HRV.Results of linear regression analysis showed that gender,and scores of PSAS total,cognitive arousal,presleep cognitive arousal,presleep somatic arousal,neuroticism,emotion oriented and LF/HF were significant correlation with FIRST score (P＜0.01 or 0.05).Conclusion Presleep cognitive and somatic arousal,neurotic character may be the premorbid characteristics of stress-related sleep disturbance,and bad stress coping strategies are easy to promote the development of insomnia.

The Stress Coping Strategies and Psychological Characteristics in Patients with Somatization Disorder / 신경정신의학

OBJECTIVES: The purpose of this study was to investigate the stress coping strategies and psychological characteristics, such as combined psychopathology and tendency of symptom interpretation, in patients with somatization disorder. METHODS: Thirty patients meeting the criteria of DSM-IV somatization disorder were compared with thirty controls. We evaluated the subjects using Symptom Checklist-90-Revised (SCL-90-R), Somato-Sensory Amplification Scale (SSAS), Symptom Interpretation Questionnaire (SIQ), and The Ways of Stress Coping Questionnaire (SCQ). Independent t-test and Pearson correlation analysis were used. RESULTS: From the results of SCL-90-R subscales, the scores of somatization, obsession-compulsion, depression, anxiety, and psychoticism were significantly higher in patients with somatization disorder than normal controls. Somatization disorder patients had greater amplification of physical sensation in SSAS and significantly higher score in physical interpretation of SIQ compared with psychological or environmental interpretation. In the SCQ of somatization disorder patients, we observed generally lower levels of total coping scores than the control group and significant positive correlation between passive coping style of SCQ and psychological interpretation of SIQ. CONCLUSION: These results show that patients with somatization disorder have various psychopathology, greater amplification of physical sensation, physical interpretation tendency of symptoms, and insufficient copying strategy.

Effect of milnacipran on insight and stress coping strategy in patients with Taijin Kyofusho.

Objective Taijin-Kyofusho (TKS) is a Japanese culture-bound syndrome similar to social anxiety disorder. Recent studies have shown antidepressants to be effective in treating TKS. The effects on insight or coping strategies have not, however, been studied. The present study investigated changes in insight and stress coping strategies during treatment with milnacipran. Method The study was a 12-week open trial in 16 patients with offensive type TKS. Offensive anxiety was assessed by an original TKS scale. Insight regarding TKS symptoms was assessed by the "Insight into obsessions and compulsions" subscale of the Yale-Brown Obsessive Compulsive Scale. Coping strategies were assessed by the Coping Inventory for Stressful Situations. The primary efficacy variable was global improvement on the Clinical Global Impression scale (CGI). Results Of the sixteen patients, only 10 completed the study and seven patients responded to the drug (a score of 2 or less on CGI at endpoint). Six patients dropped out in the first few days because of nausea. Last observation carried forward analysis (N=16) showed a significant reduction of offensive anxiety of TKS. Insight and emotional coping strategies were also significantly improved. Conclusion The results suggested that not only TKS symptoms, but also insight and stress coping, may be improved by treatment with milnacipran.
