Compositionally complex doping of spinel oxides toward high-entropy oxides is expected to enhance their electrochemical performance substantially. We successfully prepared high-entropy compounds, the oxide (ZnMgCoCu)FeO (HEOFe), lithiated oxyfluoride Li(ZnMgCoCu)FeOF (LiHEOFeF), and lithiated oxychloride Li(ZnMgCoCu)FeOCl (LiHEOFeCl) with a spinel-based cubic structure by ball milling and subsequent heat treatment. The products exhibit particles with sizes from 50 to 200 nm with a homogeneous atomic distribution.

The thieno[2,3-d]pyrimidine fragment is in the structure of many drug-like candidate derivatives with a wide range of biological activities. However, very few dipeptidyl peptidase-4 (DPP-4) inhibitors with this building block are currently known. Here, the selection of a novel DPP-4 inhibitor based on the thienopyrimidine scaffold is reported.

Department of Cardiology, German Heart Center Charité, Berlin, Germany.
The pulmonary valve (PV), although often less emphasized than other heart valves, is crucial for cardiac function and hemodynamics. Historically, the PV has been underrepresented in echocardiographic assessments due to its rare involvement in pathological conditions, particularly in adults. Additionally, the anatomical position of the PV makes it one of the most challenging valves to visualize using conventional echocardiography.

Hypothesis: The presence of hydrodynamic slip of water on smooth hydrophobic surfaces has been debated intensely over the last decades. In recent experiments, the stronger bounce of free-rising bubbles from smooth hydrophobic surfaces compared to smooth hydrophilic surfaces was interpreted as evidence for a significant water slip on smooth hydrophobic surfaces.
Experiments: To examine the possible water-slip effect, we conduct well-controlled experiments comparing the bouncing dynamics of millimeter-sized free-rising bubbles from smooth hydrophobic and hydrophilic surfaces.

This randomized-controlled study evaluates the effectiveness of a newly developed social cognition rehabilitation intervention, the modified Social Cognition Individualized Activity Lab (mSoCIAL), in improving social cognition and clinical and functional outcomes of persons with schizophrenia recruited in two Italian sites: University of Campania "Luigi Vanvitelli" in Naples and ASST Fatebenefratelli-Sacco in Milan. mSoCIAL consists of a social cognitive training module focusing on different domains of social cognition and of a narrative enhancement module. We assessed changes in social cognition, clinical characteristics and functional variables in patients with schizophrenia who participated in 10 weekly sessions of mSoCIAL or received treatment as usual (TAU).

Background: Severe or recurring major depression is associated with increased adverse childhood experiences (ACEs), heightened atherogenicity, and immune-linked neurotoxicity (INT). Nevertheless, the interconnections among these variables in outpatient major depression (OMDD) have yet to be determined. We aim to determine the correlations among INT, atherogenicity, and ACEs in OMDD patients compared to normal controls.

Difficult policy problems such as adherence to psychiatric medication can benefit from judicious selection of nudges. We present a MINDSPACE Expanded Framework including 34 insights from behavioral science in the 9 MINDSPACE principles to support a more detailed integration of behavioral science into policy.

Poly(butyl cyanoacrylate) (PBCA) nanoparticles have numerous applications, including drug and gene delivery, molecular imaging, and cancer therapy. To uncover the molecular mechanisms underlying their interactions with cell membranes, we utilized a Langmuir monolayer as a model membrane system. This approach enabled us to investigate the processes of penetration and reorganization of PBCA nanoparticles when deposited in a phospholipid monolayer subphase.

This study represents the first investigation into the ultrasonic and microwave extraction of bioactive metabolites from (red seaweed) and () (brown seaweed), with a focus on their biological activities. The research compares ultrasound-assisted extraction (UAE) with microwave-assisted extraction (MAE) utilizing a hydromethanolic solvent to evaluate their effects on these seaweeds' bioactive compounds and biological activities. The assessment included a series of antioxidant essays: DPPH, ABTS, phenanthroline, and total antioxidant capacity, followed by enzyme inhibition activities: alpha-amylase and urease.

The study investigates the development and characterization of dual-loaded niosomes incorporated into ion-sensitive in situ gel as a potential drug delivery platform for ophthalmic application. Cannabidiol (CBD) and epigallocatechin-3-gallate (EGCG) simultaneously loaded niosomes were prepared via the thin film hydration (TFH) method followed by pulsatile sonication and were subjected to comprehensive physicochemical evaluation. The optimal composition was included in a gellan gum-based in situ gel, and the antimicrobial activity, in vitro toxicity in a suitable corneal epithelial model (HaCaT cell line), and antioxidant potential of the hybrid system were further assessed.

Cutaneous cylindromas are rare, slow-growing adnexal tumors commonly found on the capillitium or face. When located on the capillitium, they can cluster together, forming a headgear-like structure that gives the characteristic "turban" appearance. Brooke-Spiegler syndrome, an autosomal dominant condition, is typically benign, though malignant transformation can occur.

Dermatofibrosarcoma protuberans (DFSP) is a rare, low-grade cutaneous sarcoma typically found on the proximal extremities and the trunk, characterized by infiltrative growth and low risk of metastasis. High rates of local recurrence or relatively large tumor sizes can significantly complicate therapeutic management, particularly when 1) surgical intervention is not adequately performed and /or 2 access to newer medications is limited or their high cost imposes a financial burden on patients. We present the case of a 63-year-old male with a histologically confirmed dermatofibrosarcoma protuberans, measuring 6 cm in diameter, located on the right dorsal region, accompanied by several confluent multifocal nodules situated infralaterally to the primary formation.

Porous polymers, including hydrogels, covalent organic frameworks (COFs), and hyper crosslinked polymers (HCPs), have become essential in biomedical research for their tunable pore architectures, large surface areas, and functional versatility. This review provides a comprehensive overview of their classification and updated synthesis mechanisms, such as 3D printing, electrospinning, and molecular imprinting. Their pivotal roles in drug delivery, tissue engineering, wound healing, and photodynamic/photothermal therapies, focusing on how pore size, distribution, and architecture impact drug release, cellular interactions, and therapeutic outcomes, are explored.
