The introduction of healthy RPE cell cultures into the subretinal space offers a potential treatment strategy. The aim of this study was the long-term culture and characterisation of RPE cells on nanofiber scaffolds.

Comparative Study of Iminodibenzyl and Diphenylamine Derivatives as Hole Transport Materials in Inverted Perovskite Solar Cells.

Perovskite solar cells (PSCs) have recently achieved over 26% power conversion efficiency, challenging the dominance of silicon-based alternatives. This progress is significantly driven by innovations in hole transport materials (HTMs), which notably influence the efficiency and stability of PSCs. However, conventional organic HTMs like PTAA, although highly efficient, suffer from thermal degradation, moisture ingress, and high cost.

Improving Photocatalytic Hydrogen Generation via Polycitric Acid-based Carbon Nanodots.

Bottom-up syntheses of carbon nanodots (CND) using solvothermal treatment of citric acid are known to afford nanometer-sized, amorphous polycitric acid-based materials. The addition of suitable co-reactants in the form of in-situ synthesized N-hetero-π-conjugated chromophores facilitates hereby the overall functionalization. Our incentive was to design a CND model that features phenazine (P-CND) - a well-known N-hetero-π-conjugated chromophore - to investigate the influence of the CND matrix on its redox chemistry as well as photochemistry.

Paucity of viral infection symptoms in patients with immune-mediated inflammatory diseases.

Objectives: Although patients with immune-mediated inflammatory diseases (IMID) are thought to be more susceptible to viral infections, it is unclear whether their presentation differs between patients with IMID and healthy controls. This study aimed to investigate the symptom pattern of common viral infections in patients with IMID and compare it with controls without IMIDs.

Design: A cross-sectional study conducted between 1 February and 30 April 2020, using a questionnaire.

Advances in the Treatment of Neonatal Coarctation of the Aorta.

Coarctation of the aorta (CoA) is a potentially life-threatening congenital and obstructive anomaly of the distal aortic arch. After constriction of the ductus arteriosus, neonates may develop critical CoA in the isthmus area and present with severe left ventricular dysfunction or even cardiac failure. Low cardiac output and abdominal hypoperfusion (distal to the coarctation) may lead to metabolic derangements and clinical deterioration.

Comprehensive genomic characterization of early-stage bladder cancer.

Understanding the molecular landscape of nonmuscle-invasive bladder cancer (NMIBC) is essential to improve risk assessment and treatment regimens. We performed a comprehensive genomic analysis of patients with NMIBC using whole-exome sequencing (n = 438), shallow whole-genome sequencing (n = 362) and total RNA sequencing (n = 414). A large genomic variation within NMIBC was observed and correlated with different molecular subtypes.

Addressing inter individual variability in CSF levels of brain derived proteins across neurodegenerative diseases.

Accurate diagnosis and monitoring of neurodegenerative diseases require reliable biomarkers. Cerebrospinal fluid (CSF) proteins are promising candidates for reflecting brain pathology; however, their diagnostic utility may be compromised by natural variability between individuals, weakening their association with disease. Here, we measured the levels of 69 pre-selected proteins in cerebrospinal fluid using antibody-based suspension bead array technology in a multi-disease cohort of 499 individuals with neurodegenerative disorders including Alzheimer's disease (AD), behavioral variant frontotemporal dementia, primary progressive aphasias, amyotrophic lateral sclerosis (ALS), corticobasal syndrome, primary supranuclear palsy, along with healthy controls.

Polygenic score distribution differences across European ancestry populations: implications for breast cancer risk prediction.

Background: The 313-variant polygenic risk score (PRS) provides a promising tool for clinical breast cancer risk prediction. However, evaluation of the PRS across different European populations which could influence risk estimation has not been performed.

Methods: We explored the distribution of PRS across European populations using genotype data from 94,072 females without breast cancer diagnosis, of European-ancestry from 21 countries participating in the Breast Cancer Association Consortium (BCAC) and 223,316 females without breast cancer diagnosis from the UK Biobank.
