Compact polymeric wavelength division multiplexer

Electronics Letters, 1999
A compact polymeric wavelength division multiplexer based on a slab waveguide and a reflective transmission grating is presented for application within the low cost data-communications market. The device channel spacing is 800 GHz (6.4 nm), measures only 4/spl times/4 mm in size, displays a polarisation-dependent wavelength shift of 0.1 nm and ...

Hepatocyte BPGM Induces RET Lactylation and Macrophage Reprogramming to Promote Tumorigenesis in Hepatocellular Carcinoma

Advanced Science, EarlyView.
Mechanistic schematic diagram.BPGM promotes the expression level of RET by increasing the lactylation of RET‐K549 and inhibiting its ubiquitination levels in HCC cells. Furthermore, BPGM in HCC cells could also promote M2 polarization in macrophages through lactate secretion. Both of the mechanisms could promote the progression of HCC. ABSTRACT Aerobic

Engineering MnPt Bimetallic Nanozymes for Cascade Enzymatic Therapy and Enhanced Radio‐Immunotherapy

Advanced Science, EarlyView.
A CD44‐targeted MnPt bimetallic nanozyme (HD@MnO2) integrates multienzyme‐like activity with cGAS–STING activation to boost radio‐immunotherapy. Through cascade biocatalysis, it depletes glutathione, relieves hypoxia, and amplifies ROS, enhancing radiotherapy‐induced DNA damage and immunogenic cell death. The nanozyme promotes dendritic cell maturation

Mineralized Cryogel/Hydrogel Constructs to Recapitulate Early Breast Cancer Bone Metastasis In Vitro

Advanced Science, EarlyView.
A new biphasic in vitro cryogel/hydrogel model of early breast cancer bone metastasis provides precise control over microenvironmental cues and microscopic access to the spatiotemporal cancer cell distribution. Deposited bone‐like mineral is observed to strongly impede the effects of biomolecular signals, as evidenced by both colonization profiles and ...

TGM2 Aggravates Acute Pancreatitis by Impairing Macrophage Efferocytosis Through Inhibition of the STAT6–GAS6 Axis

Advanced Science, EarlyView.
This study shows TGM2 is upregulated in AP, impairing macrophage efferocytosis by inhibiting the STAT6–GAS6 axis. The lactoferrin‐modified, ROS‐responsive LF‐LNP@si‐TGM2 targets pancreatic macrophages, silences TGM2, restores the axis, and alleviates AP.

Real‐Time and High‐Resolution NIR‐II‐L Imaging of Netrin‐1‐Mediated Neurovascular Coupling Driven by Dose‐Dependent Electroacupuncture

Advanced Science, EarlyView.
Disrupted neurovascular coupling contributes to ovarian dysfunction in polycystic ovary syndrome. Using near‑infrared II long‑wavelength imaging, this study visualizes how electroacupuncture dynamically regulates ovarian blood vessels in vivo. Immediate and cumulative stimulation elicit distinct vascular responses via a Netrin‐1 dependent mechanism ...
