The potential applications of contact lenses in point-of-care diagnostics and personalized medicine, along with the significance of integrating multiplexed sensing units together with drug delivery systems, have also been discussed.We disclose the first total synthesis of (+)-euphorikanin A, an ingenane-derived natural product featuring an unprecedented 5/6/7/3-fused tetracyclic skeleton. Key to the approach is a SmI2-mediated ketyl-enoate reaction that leads to the formation of two rings in a single step. The polarity-reversed cyclization proceeds in excellent yield and high diastereoselectivity. Access to ring B is effected late in the synthesis by implementation of a number of chemoselective transformations, including in situ generation of a vinyl lithium species and subsequent intramolecular attack onto an α-ketolactone.Acetaldehyde is an important chemical commodity and a building block for producing several other high-value products in the chemical industry. This has motivated the search for suitable, efficient, stable, and selective catalysts, as well as renewable raw materials such as ethanol. In this work, supported copper catalysts were prepared from CuZnAl layered double hydroxides (LDHs) with different copper contents (5, 10, and 20 wt %) for application in the ethanol dehydrogenation reaction (EDR). The samples were thoroughly characterized by a series of techniques, which allowed for analysis of all of the copper and zinc species involved in the different catalyst preparation steps and during the EDR. The results obtained by in situ quick extended X-ray absorption fine structure (EXAFS) measurements, combined with multivariate data analysis, showed that the copper content in the pristine LDH influenced the phase composition of the mixed oxide support, which consequently affected the dispersion of copper nanoparticles. The higher the copper content, the higher are the ZnAl2O4 and zinc tetrahedral prenuclei (TPN) contents, to the detriment of the ZnO content. All the samples showed high selectivity (>97%) and stability in the catalytic reactions at 300 and 350 °C, with no observed deactivation during 6 h on-stream. Although the samples with lower copper content presented higher copper dispersion and reactivity, the sample containing 20 wt % of copper outperformed the others, with greater conversion and higher activity toward acetaldehyde.

This exploratory study locates countertransference as a pan-theoretical concept, comprising of thoughts, feelings, and behaviors expressed or experienced by therapists toward their patients. It aims to understand the patterns of countertransference experienced in working with borderline personality disorder. Associations between countertransference reactions and therapist-related variables of experience and mentalization ability are also examined.

Psychotherapists (n = 117) completed the Therapist Response Questionnaire to assess patterns of countertransference experienced with a representative patient diagnosed with borderline personality disorder. Tofacitinib They also completed a measure of mentalization ability that examined self-related mentalization, other-related mentalization, and motivation to mentalize.

The profile of responses across eight countertransference dimensions is discussed, with the most strongly endorsed reactions being positive/satisfying, parental/protective, and helpless/inadequate. More experienced therapists reported less negative countertransference reactions in select dimensions. Therapists' self-reported ability to reflect on and understand their own mental states was negatively correlated with a range of difficult countertransference experiences. There were few associations between their ability to make sense of others' mental states, the motivation to mentalize, and the strength of their countertransference reactions.

The implications for countertransference management as well as therapist training and development are highlighted.

Gross's Emotion Regulation Questionnaire is one of the most widely-used and valid questionnaires for assessing emotion regulation strategies. The validity and reliability of the Persian version have not been determined and data on its psychometric properties are not available to Iranian mental health researchers. The purpose of this study was to determine the psychometric properties of the Emotion Regulation Questionnaire in Iranian students.

In this cross-sectional study, 348 students (170 males and 178 females) were selected from Shahid Beheshti University of Medical Science and Tehran University of Medical Science. The following statistical procedures were conducted correlation coefficients, factor analysis, Cronbach's alpha, and independent t tests.

The results showed that men use suppression more than women (T = -2.62, p = 0.009). Cronbach's alpha coefficients were 0.76 for the cognitive reappraisal sub-scale and 0.72 for the suppression sub-scale (excluding question 9). Six questions related to the cognitive reappraisal factor explained 30.97% of emotion regulation variance, and 3 questions related to the suppression factor explained 22.59% of emotion regulation variance. Overall, these factors explained 53.5% of emotion regulation variance. There were significant correlations between suppression and difficulties in emotion regulation, trait anxiety, and affective control. Furthermore, there was a significant correlation between cognitive reappraisal and the Five-Facet Mindfulness Questionnaire.

The results indicate that the Persian version of the ERQ is a reliable and valid instrument that can be helpful for development of further important studies of emotional regulation.

Emotion regulation refers to use of strategies to change or suppress a response to an affective experience and is an important component of an individual's subjective wellbeing. Difficulties properly regulating emotions are related to psychopathological processes.

This study assessed the factor structure of the Brazilian version of the Emotion Regulation Questionnaire (ERQ); the invariance of its psychometric parameters as a function of gender; and its convergent validity with other scales measuring affective processes.

A total of 813 adults (73.7% women), aged between 18 and 64 years and with a high educational level used an electronic platform to complete the ERQ, the Positive and Negative Affect Schedule (PANAS), the Affect Scale (AS), and the Difficulties in Emotion Regulation Scale (DERS). Factor structure, reliability, and validity of the adapted version of the ERQ were investigated.

Multi-group confirmatory factor analysis (MGCFA) revealed adequate goodness of fit for the ERQ's two-factor model (cognitive reappraisal and emotional suppression), providing evidence of invariance of its psychometric parameters as a function of gender.
