Separation of acetylene (C2H2) and carbon dioxide (CO2) is of prime importance in the petrochemical industry, but their similarities in molecular size and volatility make it particularly difficult. A desired adsorbent for highly efficient C2H2/CO2 separation should have high selectivity and C2H2 uptake simultaneously, and the introduction of functional groups into MOFs is an effective strategy to achieve this purpose. Herein, we report a titanium‐based MOF material (MIL‐125‐NH2), featuring the suitable pore sizes and amino‐functionalized pore surfaces to show the preferential adsorption of C2H2 over CO2 with both high C2H2 uptake and C2H2/CO2 selectivity. Theoretical simulation results indicate that the preferential C2H2 adsorption is mainly attributed to multiple hydrogen bonding interactions between C2H2 molecule and amino functional groups.

Objective: Embitterment and post‐traumatic embitterment disorder (PTED) is critical, merging through different cultures. We explored the prevalence and related clinical characteristics of PTED of inpatients in a general hospital in China. Method: Two hundred inpatients (aged 18–65 years) from different departments were recruited by convenient sampling and standardized diagnostic interviews of PTED. Demographic data, Post‐traumatic Embitterment Disorder Self‐Rating Scale (PTED‐21), the Patient Health Questionnaire depression scale (PHQ‐9), Generalized Anxiety Disorder‐7 (GAD‐7) and the Patient Health Questionnaire depression scale (PHQ‐15) were collected on all participants. Results: The prevalence of PTED was 21% (42/200) in inpatients in China; besides, the rate of increased syndromal embitterment is 28% (56/200), including 42 patients diagnosed with PTED. PTED was mainly associated with stressful events, such as illness, work and complicated interpersonal relationships. Rheumatology department and respiratory department have the highest and second highest prevalence of PTED among all departments. PTED‐21 scores were significantly correlated with PHQ‐9, GAD‐7 and PHQ‐15 (all P < 0.01). Conclusions: The present study shows that embitterment is a critical negative emotion in inpatients with somatic illnesses with comorbid depression, anxiety and somatic symptoms. PTED and feelings of embitterment should be given proper attention in diagnosing somatic patients, and it is crucial to enhance PTED screening and intervention in the future. Future intervention studies on post‐traumatic embitterment disorder could be done in general and especially in psychosomatic and somatic medicine. [ABSTRACT FROM AUTHOR]

Introduction: Adolescence is a critical period for physical and mental development. The effect of early life stress on mood disorders has been intensively studied in adults using rodent models, but it has been less studied in adolescents. The present study aimed to examine the effect of early life stress on anxiety‐related and depression‐like behaviors in adolescent C57BL/6 mice and the sex difference. Methods: C57BL/6 mice of both sexes were used, and early life stressors included maternal separation (MS, P2‐12, 4 hr per day), restraint stress (RS, P33 to 39, 4 hr per day), and their combination (MRS). Open field test, elevated plus maze, and forced swimming test were performed at different time points during adolescence and adulthood. Results: It was found that MS did not affect the anxiety‐related behaviors of both males and females tested on P30‐31 and P41‐42. RS decreased the anxiety level in adolescent males but did not affect it in the females. MS, RS, and MRS all significantly increased the depression‐like behavior in adolescent males, but only MRS increased the depression‐like behavior in adolescent females. All effects on adolescent males and females did not persist into adulthood. Conclusion: The present results showed that early life stress affected anxiety‐related and depression‐like behavior in adolescent mice in manners depending on the nature of stress, the developmental period, and sex.
