Article Abstract

Halide perovskites solar cells are now approaching commercialisation. In this transition from academic research towards industrialisation, standardized testing protocols and reliable dissemination of performance metrics are crucial. In this study, we analyze data from over 16,000 publications in the Perovskite Database to investigate the assumed equality between the integrated external quantum efficiency and the short circuit current from JV measurements. We find a systematic discrepancy with the JV-values being on average 4% larger. This discrepancy persists across time, perovskite composition, and device architecture, indicating the need to explore new perovskite physics and update reporting protocols and assumptions in the field.

Spiritual support is increasingly recognized as a vital component of psychological care in palliative settings, yet its impact on emotional recovery is not fully established. The objective is to systematically review the benefits of integrating spiritual support into psychotherapy for improving emotional recovery in palliative care. A systematic search of PubMed, Web of Science, and Embase was conducted (September 1-10, 2024) with no date limits.

Robotic-Assisted Versus Manual Total Hip Arthroplasty Performed for Hip Dysplasia.

J Am Acad Orthop Surg

September 2025

Introduction: Developmental dysplasia of the hip (DDH) poses challenges for component positioning during total hip arthroplasty (THA) secondary to abnormal bone morphology, soft-tissue contractures, and hip center migration. The objective of this study was to evaluate the radiographic and clinical outcomes of THA for DDH performed with robotic assistance versus manual (M) technique.

Methods: A retrospective review identified 115 patients with Crowe II to IV dysplasia undergoing primary THA at a single institution from 2016 to 2022.

Objectives: Azapirone-class drugs are partial 5-HT1A receptor agonists commonly used to treat anxiety disorders. Prior experimental studies have so far demonstrated that these drugs have low potential for dependence and problematic use and are considered safe treatment options compared with benzodiazepines. However, recent evidence suggesting the contrary raises concerns about their safety.

Proteomics Uncovers Enrichment Bias of Common Extracellular Vesicle Isolation Methods in HEK293T Cells.

J Proteome Res

Extracellular vesicles (EVs) are membranous structures consisting of lipid bilayers that are released by most cell types and serve as important mediators of intercellular communication. The HEK293T cell line model has gained considerable attention from the scientific community, particularly in the fields of engineering and drug delivery. Nevertheless, there is a dearth of systematic comparisons of the most prevalent EV isolation methodologies for HEK293T in terms of recovery and specificity.

Objective: The complexity of β-thalassaemia with associated morbidity, lifelong daily expensive treatment, and multidisciplinary care results in a considerable disease burden. Our study aimed to revisit the β-thalassaemia burden using epidemiological, clinical, and financial indicators related to patients, families, and healthcare systems.

Methods: Patient density measures, transfusion indices, complication rates, universal health coverage, and other indicators were tabulated by country and region.
