Alzheimer's disease (AD) is a complex neurodegenerative disorder having limited treatment options. The beta-site APP cleaving enzyme 1 (BACE-1) is a key target for therapeutic intervention in Alzheimer's disease. To discover new scaffolds for BACE-1 inhibitors, a ChemBridge DIVERSet library of 20,000 small molecules was employed to structure-based virtual screening. The top 45 compounds, based on docking scores and binding affinities, were tested for BACE-1 inhibitory activity using a FRET assay. Four compounds, 18 (5353320), 20 (5262831), 29 (5784196) and 32 (5794006) demonstrated more than 35 % inhibitory activity at 10 μM. Notably, pyrazole-5-carbohydrazide 29 (5784196) exhibited BACE-1 inhibition with an IC value of 14.5 μM and a ki value of 0.25 μM. Additionally, it also inhibits the self-aggregation of β-amyloid, with IC value of 14.87 μM. Molecular modeling and dynamics simulations provided insights into its interaction pattern and stability of the enzyme-inhibitor complex. These findings suggest that virtual screening is an efficient and cost-effective method for identifying potential leads for AD.

Introduction: The transition from traditional laparoscopy to robotic surgery marks a significant chage in surgical practice. An understated aspect of this transition may be the three dimensional (3D) view from the surgical console. This study hypothesises that acclimatisation with 3D virtual reality (VR) video may enhance robotic simulator performance in novice robotic surgeons.

Non-small cell lung cancer (NSCLC) is an aggressive malignancy with a poor prognosis. Abnormal expression of focal adhesion kinase (FAK) is closely linked to NSCLC progression, highlighting the need for effective FAK inhibitors in NSCLC treatment. In this study we conducted high-throughput virtual screening combined with cellular assays to identify potential FAK inhibitors for NSCLC treatment.

Introduction: Virtual reality (VR) technology is increasingly being explored as a medium for delivering mindfulness-based interventions. While studies have investigated the feasibility and efficacy of VR-based mindfulness interventions, there has been limited synthesis of user experiences and perceptions across diverse applications, hindering the iterative refinement of these technologies and limiting evidence-based guidance for effective deployment in real-world settings. This systematic review aims to comprehensively identify, appraise and synthesise qualitative research on end-user experiences and perceptions of VR-based mindfulness interventions.

Introduction: Appendiceal neuroendocrine neoplasms are rare lesions which are generally incidentally discovered during or after appendectomies. Recent advances have refined their classification and improved diagnostic rates, highlighting their distinct pathologic and clinical presentations. The present study aimed to assess the characteristics and outcomes of appendiceal neuroendocrine neoplasms using data from the U.

Over three decades, statistical parametric mapping has transformed neuroimaging from descriptive mapping to causal inference, placing generative models at the core of causal explanations for brain function. It inspired to a large degree The Virtual Brain, which builds subject-specific digital twins from multimodal data, enabling brain simulations and exploration. Both frameworks converge at parameter estimation, where model and data meet, providing the mathematical manifestation of cause-effect in pathophysiology.
