Article Abstract
This study presents the synthesis and characterization of novel oxychloride tellurite glasses codoped with Sm/Yb. These materials were investigated for their potential applications as spectral converters to enhance the efficiency of silica-based solar cells. Optical spectroscopy revealed the successful incorporation of both rare-earth ions in the glass matrix. It was observed that with the increase of Yb ion concentration, the lifetime of the G state of Sm ions decreased considerably, indicating an efficient energy transfer mechanism between the Sm/Yb pair. A notable energy transfer efficiency of 76% was achieved for the sample containing 3 mol % of YbCl. The observed visible-to-near-infrared spectral conversion properties make these glasses promising candidates for improving the performance of silicon solar cells by better matching the solar spectrum to the optimal response range of a photovoltaic device.

A multi-omics recovery factor predicts long COVID in the IMPACC study.

Background: Following SARS-CoV-2 infection, ~10-35% of COVID-19 patients experience long COVID (LC), in which debilitating symptoms persist for at least three months. Elucidating biologic underpinnings of LC could identify therapeutic opportunities.
Methods: We utilized machine learning methods on biologic analytes provided over 12-months after hospital discharge from >500 COVID-19 patients in the IMPACC cohort to identify a multi-omics "recovery factor", trained on patient-reported physical function survey scores.

Neuropeptide Y (NPY) and the voltage-gated potassium channel Kv1.3 are closely associated with breast cancer progression and apoptosis regulation, respectively. NPY receptors (NPYRs), which are overexpressed in breast tumors, contribute to tumor growth, migration, and angiogenesis.

Introduction: The definition of Leber's hereditary optic neuropathy (LHON) does not take into account a preclinical phase during which the thickness of retinal nerve fiber layer (RNFL) is increased, prior to optic nerve atrophy, reducing the chances of visual recovery.
Objectives: Search for a metabolomic signature characterizing this preclinical phase and identify biomarkers predicting the risk of LHON onset.
Methods And Results: The blood and tear metabolomic profiles of 90 asymptomatic LHON mutation carriers followed for one year will be explored as a function of RNFL thickness and compared to those of a healthy control.

Introduction: Knockout of the Fmo5 gene in mice led to a lean, slow-ageing phenotype characterised by the presence of 2,3-butanediol isomers in their urine and plasma. Oral treatment of wildtype mice with 2,3-butanediol led to a low cholesterol, low epididymal fat phenotype.
Objectives: Determine if significant, heterozygous coding variations in human FMO5 would give rise to similar clinical and metabolic phenotypes in humans, as in C57BL/6J mice with knockout of the Fmo5 gene and in particular, increased excretion of 2,3-butanediol.

Alzheimer's disease (AD) is the most common, complex, and untreatable form of dementia which is characterized by severe cognitive, motor, neuropsychiatric, and behavioural impairments. These symptoms severely reduce the quality of life for patients and impose a significant burden on caregivers. The existing therapies offer only symptomatic relief without addressing the underlying silent pathological progression.
