A Mitochondria‐Specific Nanomedicine for Synergistic Chemo‐Photothermal Therapy and Immunogenic Activation Against Breast Cancer

Advanced Science, EarlyView.
Peptide dendrimer–based nanoplatform with mitochondria‐targeting capability was developed for synergistic chemo‐photothermal therapy. The system promotes efficient transcytosis, induces mitochondrial dysfunction, triggers immunogenic cell death (ICD), and enhance antitumor immunity by promoting dendritic cell maturation and T‐cell activation, resulting

Laparoscopic Delivery of a MnO2‐P‐ICG Patch for Photodynamic Therapy and NK Cell‐Driven Immunotherapy in Hepatocellular Carcinoma

Advanced Science, EarlyView.
This study proposes a flexible MnO2‐P‐ICG nanofiber patch for laparoscopic treatment of liver tumors. The patch alleviates tumor hypoxia and induces photodynamic therapy (PDT) triggered immunogenic cell death, thereby activating the cGAS‐STING pathway and, in synergy with pachymaran, promoting NK cell–mediated innate immunity. This synergistic strategy

ADME potential of porphyrin derivative from petroleum [PDF]

BIO Web of Conferences
Chlorins are tetrapyrrole pigments that are formally described as partially hydrogenated porphyrins, specifically dihydroporphyrins. This structural difference gives them distinct chemical and photophysical properties that are essential for their ...

Advances and Perspectives in Graphene‐Based Quantum Dots Enabled Neuromorphic Devices

Advanced Science, EarlyView.
Graphene‐based QDs are zero‐dimensional carbon nanomaterials with pronounced quantum confinement and tunable electronic structures. Herein, we summarize their synthesis strategies and functionalization methods, and highlight their functional roles and operating mechanisms in devices, as well as recent advances in neuromorphic electronics. We anticipate

Use of antihypertensive drugs and risk of keratinocyte carcinoma: A meta‐analysis of observational studies [PDF]

, 2018
Purpose Current epidemiologic evidence on the association between antihypertensive drugs and keratinocyte carcinoma (KC) risk is inconsistent. We sought to quantify this association by meta‐analysis of observational studies.

Helicalization of Covalent Organic Framework Nanofibers with Amplified Spin Polarizability for Boosting Photocatalytic Hydrogen Evolution

Advanced Science, EarlyView.
A non‐covalent chirality‐induced strategy via chiral solvents is presented to synthesize helical 2D COF nanofibers with high crystallinity, high chirality, and high spin polarization. The helical structure enhances the concentration of photogenerated charges, suppresses exciton recombination, and extends carrier lifetimes, thereby significantly ...
