2D transition metal dichalcogenide MoS2 nanosheets are increasingly attracting interests due to their promising applications in materials science and biomedicine. However, their biocompatibility and their biodegradability have not been thoroughly studied yet. Here, we investigated the biodegradability of exfoliated pristine and covalently functionalized MoS2 (f-MoS2). First, biodegradability of these nanomaterials was evaluated using plant horseradish peroxidase and human myeloperoxidase. The results revealed that the enzymatic degradability rate of MoS2 and f-MoS2 was slower than in the case of the simple treatment with H2O2 alone.In parallel, high biocompatibility of both pristine and f-MoS2 nanosheets was found up to 100 µg mL -1 both in cell lines (HeLa and Raw264.7) and primary immune cells. In addition, no immune cell activation and minimal pro-inflammatory cytokine release were observed in RAW264.7 and human monocyte-derived macrophages, suggesting a negligible cellular impact of such materials. Furthermore, the effects of degraded MoS2 and partially degraded f-MoS2 products on cell viability and activation were studied in cancer and immune cells. A certain cytotoxicity was measured at the highest concentrations. Finally, to prove that the

In the wake of the sudden spread of COVID-19, a large amount of the Italian population practiced incongruous behaviors with the protective health measures. The present study aimed at examining psychological and psychosocial variables that could predict behavioral compliance. An online survey was administered from 18–22 March 2020 to 2766 participants. Paired sample t-tests were run to compare efficacy perception with behavioral compliance. Mediation and moderated mediation models were constructed to explore the association between perceived efficacy and compliance, mediated by self-efficacy and moderated by risk perception and civic attitudes. Machine learning algorithms were trained to predict which individuals would be more likely to comply with protective measures. Results indicated significantly lower scores in behavioral compliance than efficacy perception. Risk perception and civic attitudes as moderators rendered the mediating effect of self-efficacy insignificant. Perceived efficacy on the adoption of recommended behaviors varied in accordance with risk perception and civic engagement. The 14 collected variables, entered as predictors in machine learning models, produced an ROC area in the range of 0.82–0.91 classifying individuals as high versus low compliance. Overall, these findings could be helpful in guiding age-tailored information/advertising campaigns in countries affected by COVID-19 and directing further research on behavioral compliance.

Narcissistic personality disorder (NPD) is one of the most challenging clinical syndromes to treat in psychotherapy, especially due to the difficulties of establishing a good enough therapist-patient relationship. Countertransference responses to NPD can be particularly intense, frustrating, and difficult to manage, as is often reported in the clinical literature though not clearly supported empirically. The aims of this study were to (a) investigate the relationship between patients' NPD and therapists' responses; (b) examine the associations between patient, clinician, therapy variables and clinicians' reactions during treatment of NPD patients; and (c) provide an empirically derived portrait of countertransference with NPD. A sample of psychiatrists and clinical psychologists (N = 67) completed the Therapist Response Questionnaire to identify patterns of countertransference, the Shedler-Westen Assessment Procedure-200, and the Global Assessment of Functioning Scale to assess the personality pathology and psychosocial functioning of a patient in their care. The results showed that NPD was positively associated with hostile/angry, criticized/devalued, helpless/inadequate, and disengaged countertransference and negatively associated with therapists' positive response, regardless of patients' personality and psychosocial functioning. NPD patients with stronger traits of cluster B personality pathology tended to elicit more negative and heterogeneous countertransference reactions than NPD patients without these features. The countertransference patterns with NPD patients were not strongly influenced by the variables of clinicians and therapy, with the exception of clinical experience. Overall, the portrait of therapists' reactions to NPD provided a clinically nuanced and empirically founded description strongly resembling theoretical-clinical accounts. The therapeutic implications of these findings were discussed. (PsycINFO Database Record

The present review clarifies how a deep examination of the contribution of therapists' subjective characteristics can help elucidate the complex association between relational and technical factors related to the outcome of psychodynamic treatments.
