Structure, photoluminescence, Judd–Ofelt analysis, and thermal stability studies of Ho3+/Yb3+ Co-doped YNbO4 green phosphors

AIP Advances, 2023
A series of YNbO4:Ho3+/Yb3+ phosphors with varying concentrations of Yb3+ were synthesized using a high-temperature solid-state method. To ascertain the presence, structure, and purity of YNbO4:Ho3+/Yb3+, the crystal structure of the luminescent powder ...

Emerging role of ARHGAP29 in melanoma cell phenotype switching

Molecular Oncology, EarlyView.
This study gives first insights into the role of ARHGAP29 in malignant melanoma. ARHGAP29 was revealed to be connected to tumor cell plasticity, promoting a mesenchymal‐like, invasive phenotype and driving tumor progression. Further, it modulates cell spreading by influencing RhoA/ROCK signaling and affects SMAD2 activity. Rho GTPase‐activating protein

Probing dark exciton diffusion using photovoltage

Nature Communications, 2017
Exciton diffusion plays a role in many optoelectronic devices. In some materials, this migration cannot be detected using photoluminescence. Mullenbachet al. use photovoltage measurements to extract the diffusion length in organic photovoltaic cells, and

Luminescence measurement of Feldspar

, 2022
Abstract In their ideal form, feldspars are wide bandgap (> 5 eV) insulators with a well-defined crystal structure. A natural sample may contain different feldspar phases, disorders, twinning effects, fractures, dislocations, and highly variable impurity contents.

PYCR1 inhibition in bone marrow stromal cells enhances bortezomib sensitivity in multiple myeloma cells by altering their metabolism

Molecular Oncology, EarlyView.
This study investigated how PYCR1 inhibition in bone marrow stromal cells (BMSCs) indirectly affects multiple myeloma (MM) cell metabolism and viability. Culturing MM cells in conditioned medium from PYCR1‐silenced BMSCs impaired oxidative phosphorylation and increased sensitivity to bortezomib.

Patient‐specific pharmacogenomics demonstrates xCT as predictive therapeutic target in colon cancer with possible implications in tumor connectivity

Molecular Oncology, EarlyView.
This study integrates transcriptomic profiling of matched tumor and healthy tissues from 32 colorectal cancer patients with functional validation in patient‐derived organoids, revealing dysregulated metabolic programs driven by overexpressed xCT (SLC7A11) and SLC3A2, identifying an oncogenic cystine/glutamate transporter signature linked to ...
