Determination of Trace Amounts of Boron in Polysilicon by Differential Pulse Voltammetry After Hydrofluoric Acid/Nitric Acid Treatment

International Journal of Electrochemical Science, 2011
A voltammetric method for the determination of trace amounts of boron in polysilicon is proposed. The effects of several chemicals and instrumental variables were studied, and optimized operating conditions were identified.

Hyperlipidemia Aggravates Alveolar Bone Loss via Periodontal Ligament Stem Cell Ferroptosis Through GSK3β Dependent Ubiquitin‐Mediated NRF2 Degradation

Advanced Science, EarlyView.
Lipid metabolic stress triggers ferroptosis in PDLSCs through the GSK3β/NRF2 pathway, thereby aggravating periodontal bone loss. Upregulated GSK3β promotes NRF2 ubiquitination and proteasomal degradation via β‐TrCP, suppressing NRF2 nuclear translocation and antioxidant target expression.

Targeting Endogenous Lipophagy: A Novel Strategy to Enhance MSC Osteogenesis and Mineralization for Senile Osteoporosis Therapy

Advanced Science, EarlyView.
Schematic representation of the role of lipophagy in bone mesenchymal stem cells(MSCs). In healthy MSCs, functional lipophagy efficiently degrades lipid droplets to support oxidative phosphorylation and cellular energy production, thereby facilitating osteogenic differentiation and matrix mineralization.

Adjusting UV‐Vis Spectrum of Alizarin by Insertion of Auxochromes

ChemistryOpen
First synthesized in 1868, alizarin became one of the first synthetic dyes and was widely used as a red dye in the textile industry, making it more affordable and readily available than the traditional red dyes derived from natural sources.

Alizarin Red S staining of MSCs cultured for 14 days on standard polystyrene tissue culture plates.

, 2022
(A-C) MSCs were cultured for 14 days in either osteogenic differentiation media or (D-F) non-differentiation media. On day 14, cells were stained with Alizarin Red S dye. (B and E) Images taken at 4x objective magnification and (C and F) at 20x objective

A Viscous DES‐AAV‐Foxo1 Delivery System With High Transfection Efficiency for the Treatment of Corneal Endothelial Dysfunction by Restoring Mitochondria‐ER Contacts

Advanced Science, EarlyView.
High glucose triggers corneal endothelial dysfunction by impairing FOXO1‐mediated ITPR1 transcription, leading to disrupted mitochondria‐associated membrane (MAM) integrity and defective ER‐to‐mitochondria Ca2+ transfer. This study develops an innovative viscous DES‐AAV‐Foxo1 delivery system with enhanced transfection efficiency. This non‐invasive gene

Aptamer‐Directed Porous DNA Nanocomposite Hydrogel for Active Pulp Preservation: Immunomodulation, Stem Cell Recruitment and Reparative Dentinogenesis

Advanced Science, EarlyView.
This study presents an injectable DNA‐based porous hydrogel integrating catechol motifs and targeting aptamers for pulpitis management. Upon in situ crosslinking, the scaffold actively recruits endogenous dental pulp stem cells, restores redox homeostasis, and modulates immune responses.
