Re-design and evaluation of diclofenac-based carborane-substituted prodrugs and their anti-cancer potential.

In this study, we investigated a novel anti-cancer drug design approach by revisiting diclofenac-based carborane-substituted prodrugs. The redesigned compounds combine the robust carborane scaffold with the oxindole framework, resulting in four carborane-derivatized oxindoles and a unique zwitterionic amidine featuring a nido-cluster. We tested the anti-cancer potential of these prodrugs against murine colon adenocarcinoma (MC38), human colorectal carcinoma (HCT116), and human colorectal adenocarcinoma (HT29).

Classical View on Nonclassical Crystal Growth in a Biological Setting.

Crystallization by amorphous particle attachment, a nonclassical crystal growth mode, is prevalent in minerals formed by living tissues. It allows the organism to intervene at every step of crystal growth, i.e.

The prognostic influence of hospital type, method of first histological confirmation and time to chemotherapy in patients with advanced primary ovarian cancer.

Purpose: Ovarian cancer is the fifth most common cancer in women and the leading cause of death of all gynecological malignancies. Prognosis is determined by optimal surgical outcome (macroscopic complete resection) most commonly achieved in tertiary hospitals. We investigated whether tertiary versus non-tertiary hospital as the location of an initial diagnostic intervention for histological confirmation before cytoreductive surgery versus immediate primary debulking surgery impacts outcome in patients with advanced ovarian cancer.

PNPLA3 in Alcohol-Related Liver Disease.

The discovery of PNPLA3 as a genetic risk factor for liver disease has transformed our understanding of the pathogenesis of alcohol-related liver disease (ALD). The recent reclassification of fatty liver disease as steatotic liver disease (SLD), introducing metabolic dysfunction and alcohol-related liver disease (MetALD), has highlighted how genetic and environmental factors synergistically drive liver damage. The PNPLA3 rs738409 variant stands as a paradigmatic example of gene-environment interaction, where its effect on liver disease is dramatically amplified by alcohol consumption, obesity and type 2 diabetes.

Advancing the personalized advantage index (PAI): a systematic review and application in two large multi-site samples in anxiety disorders.

Previous studies have demonstrated its utility in retrospective evaluations across various settings. In this study, we explored the effect of different methodological choices in predictive modelling underlying the PAI.

Disentangling the perceptual underpinnings of autism: Evidence from a face aftereffects experiment.

Existing literature has documented diminished norm-based adaptation (aftereffects) across several perceptual domains in autism. However, the exact underlying mechanisms, such as sensory dominance possibly caused by imprecise priors and/or increased sensory precision, remain elusive. The "Bayesian brain" framework offers refined methods to investigate these mechanisms.

Frontal midline theta reveals temporal dynamics of target amplification and distracter inhibition during mental set-shifting.

When humans shift between tasks, they initially show slower responses in the new task than in the previous one. Persisting attentional settings are increasingly recognized as a source for these shifting costs. However, the extent to which specific mechanisms underlying information selection and interference control contribute to this phenomenon remains less clear.

Incorporation of metal-doped silicate microparticles into collagen scaffolds combines chemical and architectural cues for endochondral bone healing.

Regeneration of large bone defects remains a clinical challenge until today. While existing biomaterials are predominantly addressing bone healing via direct, intramembranous ossification (IO), bone tissue formation via a cartilage phase, so-called endochondral ossification (EO) has been shown to be a promising alternative strategy. However, pure biomaterial approaches for EO induction are sparse and the knowledge how material components can have bioactive contribution to the required cartilage formation is limited.

Psychometric Properties of a Computer-Administered Self-Report Version of the Diagnostic Interview for Sexual Dysfunctions in Women (DISEX-F-SR).

The Diagnostic Interview for Sexual Dysfunctions in Women (DISEX-F) is a clinician-administered instrument allowing for an ICD-11 and DSM-5-compliant assessment of female sexual dysfunctions. Due to limited time and resources in practice and research, as well as patients' reticence in discussing sexual issues, a computer-administered self-report version was developed (DISEX-F-SR). This study aimed to collect initial data on its psychometric properties.

On a novel gradient flow structure for the aggregation equation.

The aggregation equation arises naturally in kinetic theory in the study of granular media, and its interpretation as a 2-Wasserstein gradient flow for the nonlocal interaction energy is well-known. Starting from the spatially homogeneous inelastic Boltzmann equation, a formal Taylor expansion reveals a link between this equation and the aggregation equation with an appropriately chosen interaction potential. Inspired by this formal link and the fact that the associated aggregation equation also dissipates the kinetic energy, we present a novel way of interpreting the aggregation equation as a gradient flow, in the sense of curves of maximal slope, of the kinetic energy, rather than the usual interaction energy, with respect to an appropriately constructed transportation metric on the space of probability measures.

[Barriers and facilitators to the use of mental health prevention programs among preschool- and elementary school-aged children].

Background And Aims: Emotional and behavioural problems occur frequently in childhood and are usually associated with burdens on children, families, and society. Preventive interventions could reduce these burdens, but are rarely used despite their availability and effectiveness. The aim was to identify general, individual, structural, and family-related barriers/facilitators to potential and actual participation in prevention programs.

Modified Delphi Procedure to Achieve Consensus for the Concept of a National Curriculum for Minimally Invasive and Robot-assisted Surgery in Germany (GeRMIQ).

The rapid development of minimally invasive surgery (MIS) and robot-assisted surgery (RAS) requires standardized training to ensure high-quality patient care. In Germany, there is currently a lack of a standardized curriculum that teaches these specialized skills. The aim of this study is to find a consensus for the development of a nationwide curriculum for MIS and RAS with the subsequent implementation of the consented content.

Toward better drivability: Investigating user preferences for tip-in acceleration profiles in electric vehicles.

Vehicle drivability, defined as the smooth operation and stability of a vehicle in response to driver inputs, significantly influences the performance of passenger cars. Among various driving conditions, tip-in acceleration is one of the most frequently encountered and crucial factors affecting drivability. This study investigates preferred longitudinal acceleration profiles for electric vehicles through subjective evaluations obtained from on-road tests.

Two-Dimensional Conjugated Metal-Organic Frameworks for Photochemical Transformations.

Photochemical transformation represents an attractive pathway for the conversion of earth-abundant resources, such as HO, CO, O, and N, into valuable chemicals by utilizing sunlight as an energy source. Recently, two-dimensional conjugated metal-organic frameworks (2D c-MOFs) have emerged as the focal points in the field of photo-to-chemical conversion due to their advantages in light harvesting, electrical conductivity, mass transport, tunable electronic and porous structures, as well as abundant active sites. In this review, we highlight various physical and chemical features of 2D c-MOFs that can contribute to enhanced photo-induced exciton generation, charge transport, proton migration and redox catalysis.
