5 mV dec-1) can also be achieved.Highly curved toroidal micelles with diameters as small as 100 nm have been successfully constructed by self-assembly of amphiphilic block copolymers. These structures may have potential applications in gene or drug delivery. Experimental observations suggest that toroidal micelles likely originate from spherical or disc-like micelles which are tricked into forming toroidal micelles upon external stimuli ('smart' materials). Since self-assembly of polymeric and lipid surfactants is guided by the same physical principles, we hypothesize that 'smart' lipid surfactants can be equivalently tricked into forming highly curved toroidal micelles that are tenfold smaller (≃10 nm diameter). Paradoxically, these 'nano rings' have never been observed. Using coarse-grained molecular dynamics (MD) simulations in conjunction with a state-of-the-art free energy calculation method (a string method), we illustrate how a thermo-responsive lipid surfactant is able to form toroidal micelles. These micelles originate from disc-liknevertheless remains conserved even at different length scales.A novel in-situ N-doped carbon nanoparticles (NCNs) was prepared through direct pyrolysis of N-rich polyaniline (PANI) without using external N-containing precursor and the as-prepared materials were employed as metal-free peroxydisulfate (PDS) activator for bisphenol A (BPA) degradation. The catalyst derived from PANI carbonization at 900 °C (NCNs-9) displayed the excellent catalytic activity to activate PDS, resulting in 96.0% BPA degradation efficiency within 20 min. The catalytic activity of NCNs was closely related to their structure-composition, and higher graphitic N content and larger BET surface area were beneficial to the generation of reactive oxygen species (ROS). The quenching tests and electron paramagnetic resonance (EPR) demonstrated that BPA degradation in PDS/NCNs system was accomplished via non-radical (1O2) and radical ( ·OH, SO4·-, and O2·-) pathways, in which O2·- was the main ROS. The origin of O2·- was the conversion of dissolved oxygen and the activation of PDS. The possible degradation pathways of BPA were also proposed. This study might provide inspirations to design in-situ N-doped carbon nanoparticles as the PDS activator for efficient degradation of persistent organic compound via advanced oxidation processes (AOPs).

The study explores the association between pain and functional impairment in patients with partially remitted MDD, considering both clinician and patient reported outcomes.

Multicenter, observational, and cross-sectional study, with 583 outpatients with partially remitted MDD. Measures of pain intensity (VAS), functional impairment (SOFAS), depressive symptomatology (HAM-D6), and remission from MDD and functional status from a patient-centered perspective (RDQ) were collected. VAS scores (cut-off 30) were used to divide the sample in two groups no pain (n=274) and pain (n=309). Descriptive data, correlation and regression analyses were obtained.

Functional impairment (SOFAS) and pain (VAS) were negatively and significantly correlated in the total sample, and in the group with pain. Lower pain predicted higher functioning. The pain sub-sample was older, less educated, with higher medical comorbidities, higher HAM-D6 scores, and lower functionality (SOFAS). In the RDQ, the pain group showed significantly higher scores in the symptom-related subscales, and lower scores in the subscales related to positive mental health, functioning and wellbeing.

Correlational and observational design. The criteria and instruments used to measure pain and to define a threshold might limit the generalizability of findings.

Pain and functionality should be assessed and treated in patients with MDD in partial remission. Our results indicate that functionality should be assessed with a broader perspective, that also considers positive mental health features.

Though grief, anxiety, and depression often co-occur, existing evidence mostly focus on any two of them at a time. NVP-TNKS656 Our study examined the relationships among the three clusters of symptoms.

A Chinese community sample of 101 bereaved individuals participated at T1. We utilized Bayesian Structural Equation Modelling (BSEM) to conduct cross-lagged analyses on three-wave panel data (T1 at one-month post-loss, T2 at four-months, and T3 at seven-months).

BSEM findings confirmed the presence of distinctive developmental paths for complicated grief (CG), anxiety, and depressive symptoms. Three simplex models showed that anxiety, CG symptoms, and depressive symptoms maintained high consistency. In cross-lagged models, anxiety at T1 was a significant predictor of depressive symptoms (standardized estimate B=0.386*) and CG symptoms (standardized estimate B=0.300*) at T2. The remaining positive directions (0.338*, 0.256*) in the final model suggest the important role of anxiety at early bereavement, while at a later stage, T2 CG contributed to depressive symptoms at T3 (0.356*).

In addition to attrition, the overall sample size was limited. Data were based on self-report. Future research with repeated measures and Bayesian informative priors would be more useful to establish relational patterns of symptoms.

In our models, the reduction in anxiety symptoms contributed to the development of depressive and CG symptoms, and these results should be replicated. Theories of mechanisms underlying post-loss anxiety can be explored as a potential means of reducing later symptoms.

Telephone-administered psychotherapy (tCBT) and internet-based treatments (iCBT) may overcome barriers to mental health treatment. TCBT has demonstrated efficacy similar to traditional psychotherapy, however, few studies have compared iCBT to efficacious interventions. This exploratory study examined the noninferiority of iCBT relative to tCBT. We also explored pretreatment moderators of outcome and assessed treatment dropout.

As a secondary exploratory analysis of a 304-participant randomized noninferiority trial, we compared iCBT, the first level of a stepped-care intervention, with tCBT on depression outcome after 5 weeks of treatment (prior to stepping). Multiple linear regression models were fit to examine moderators of 5-week depression. Differences in dropout were examined using Kaplan-Meier survival analysis.

After 5 weeks of treatment, both interventions significantly reduced depression severity. The effect size difference between the two interventions was d=0.004 [90% CI=-0

19 to 0

19]; the CI did not cross the non-inferiority margin.
