Character strengths as predictors of general and academic self-efficacy in university students.

Positive psychology has introduced the concept of character strengths, which are positive traits fundamental to well-being and mental health. Research on university students has shown that these strengths impact psychoeducational variables and personal functioning, acting as a protective factor in the general and student populations. This study aims to analyze the predictive relationships between character strengths and general self-efficacy and determine their joint contribution in predicting academic self-efficacy.

In vivo pharmacokinetic study and PBPK modeling: Comparison between 3D-printed nanocrystals and solid dispersions.

The solubility of drugs remains one of the most challenging aspects of formulation development. Several technologies exist to enhance the properties of poorly soluble drugs, with nanocrystal (NC) and solid dispersion (SD) technologies being among the most important. This work compared NCs and SDs under identical conditions using albendazole as a model drug and 3D printing technology as the delivery method.

Antimicrobial photodynamic therapy effects mediated by methylene blue in surfactant medium as an adjuvant treatment of teeth with apical periodontitis and presence of fistula-Protocol for randomized, controlled, double-blind clinical trial.

Objective: This study aims to evaluate the efficacy of photodynamic therapy as an adjunct to conventional endodontic treatment in patients with apical periodontitis and fistulas. In this study, a fistula is characterized as a pathological conduit originating from the infected region at the root apex of the tooth, traversing the oral mucosa, and extending to the external surface of the gingiva. This pathological condition frequently complicates the management of endodontic infections, thereby necessitating the evaluation of supplementary therapeutic interventions.

Unveiling the hidden diversity and functional role of Chloroflexota in full-scale wastewater treatment plants through genome-centric analyses.

The phylum Chloroflexota has been found to exhibit high abundance in the microbial communities from wastewater treatment plants (WWTPs) in both aerobic and anaerobic systems. However, its metabolic role has not been fully explored due to the lack of cultured isolates. To address this gap, we use publicly available metagenome datasets from both activated sludge (AS) and methanogenic (MET) full-scale wastewater treatment reactors to assembled genomes.

Effects of Paradoxical Sleep Deprivation on MCH and Hypocretin Systems.

Melanin-concentrating hormone (MCH) and hypocretins (Hcrt) 1 and 2 are neuropeptides synthesized in the lateral hypothalamic area by neurons that are critical in the regulation of sleep and wakefulness. Their receptors are located in the same cerebral regions, including the frontal cortex and hippocampus. The present study aimed to assess whether 96 hours of paradoxical sleep deprivation alters the functioning of the MCH and hypocretin systems.

A worldwide assessment of the mechanical ventilation in patients with acute exacerbations of chronic obstructive pulmonary disease. Analysis of the VENTILAGROUP over time. A retrospective, multicenter study.

Broaden properties of ambroxol hydrochloride as an antibiofilm compound.

Biofilm-associated microorganisms can cause many infections and are an important cause of resistance to several antimicrobials. The antibiotic crisis has led to a pressing need for new therapeutic tools. Ambroxol is frequently used as a mucolytic agent in respiratory diseases with increased mucus production.

Inviscid fixed point of the multidimensional Burgers-Kardar-Parisi-Zhang equation.

A new scaling regime characterized by a z=1 dynamical critical exponent has been reported in several numerical simulations of the one-dimensional Kardar-Parisi-Zhang and noisy Burgers equations. In these works, this scaling, differing from the well-known KPZ one z=3/2, was found to emerge in the tensionless limit for the interface and in the inviscid limit for the fluid. Based on functional renormalization group, the origin of this scaling has been elucidated.

Postoperative Activity Restrictions After Reconstructive Pelvic Surgery.

Importance: Restrictive physical activity after pelvic reconstructive surgery is recommended, although the optimal duration and intensity are not standardized.

Objective: This systematic review and meta-analysis aimed to evaluate the existing literature comparing clinical outcomes for liberal postoperative physical activity versus standard of care, defined as restricted postoperative physical activity, after pelvic reconstructive surgery.

Study Design: PubMed, CENTRAL, Scopus, Web of Science, and CINAHL databases were searched for observational and randomized studies comparing liberal postoperative physical activity and standard of care in women undergoing pelvic reconstructive surgery, reporting anatomic and functional outcomes.

Objective: To synthesize the associations between objectively measured daily step counts and depression in the general adult population.

Predicting attentional focus: Heartbeat-evoked responses and brain dynamics during interoceptive and exteroceptive processing.

Attention shapes our consciousness content and perception by increasing the probability of becoming aware and/or better encoding a selection of the incoming inner or outer sensory world. Engaging interoceptive and exteroceptive attention should elicit distinctive neural responses to visceral and external stimuli and could be useful in detecting covert command-following in unresponsive patients. We designed a task to engage healthy participants' attention toward their heartbeats or auditory stimuli and investigated whether brain dynamics and the heartbeat-evoked potential (HEP) distinguished covert interoceptive-exteroceptive attention.

Contextual factors influencing bubble continuous positive airway pressure implementation for paediatric respiratory distress in low-income and middle-income countries: a realist review.

Background: Bubble continuous positive airway pressure (bCPAP) is a low-cost, non-invasive respiratory support therapy for children with respiratory distress, but its effectiveness is dependent on the context. We aimed to understand contextual factors influencing bCPAP implementation for children aged 1-59 months in low-income and middle-income countries (LMICs) and to develop a theory explaining how these factors influence implementation outcomes.

Methods: In this realist review, we generated an initial programme theory comprising candidate context-mechanism-outcome configurations (CMOCs) via review of key references and team discussion.

Cortical tracking of speakers' spectral changes predicts selective listening.

A social scene is particularly informative when people are distinguishable. To understand somebody amid a "cocktail party" chatter, we automatically index their voice. This ability is underpinned by parallel processing of vocal spectral contours from speech sounds, but it has not yet been established how this occurs in the brain's cortex.

Intra-operative and post-operative management of conduits for coronary artery bypass grafting: a clinical consensus statement of the European Society of Cardiology Working Group on Cardiovascular Surgery and the European Association for Cardio-Thoracic Surgery Coronary Task Force.

The structural and functional integrity of conduits used for coronary artery bypass grafting is critical for graft patency. Disruption of endothelial integrity and endothelial dysfunction are incurred during conduit harvesting subsequent to mechanical or thermal injury and during conduit storage prior to grafting, leading to acute thrombosis and early graft failure. Late graft failure, in particular that of vein grafts, is precipitated by progressive atherogenesis.
