PTT packet delay analysis for GPRS/GSM links

open access: yes, 2006
Push-to-Talk (PTT) is a new mobile service that enables fast-access and two-way communication between two or more users. This paper develops an approximate evaluation model for PTT delay performance in GPRS/GSM networks based on a quasi-stationary ...

Sprayable MXene Hydrogels With Composition‐Driven Interfacial Stabilization and on‐Skin Gelation for Conformal Postsurgical Photothermal Therapy

open access: yesSmall, EarlyView.
A sprayable MXene‐loaded thermosensitive hydrogel was developed for postoperative melanoma treatment. Molecular simulations combined with experimental analyses demonstrated that polymer composition regulates MXene oxidation. The optimized hydrogel effectively preserved photothermal performance under physiological conditions, enabling efficient near ...

HER2‐Targeted AIE Nanotheranostics Overcome SHR‐A1811 Resistance via Immunogenic Pyroptosis and Tumor‐Associated Macrophage Reprogramming in Breast Cancer

open access: yesSmall, EarlyView.
HER2‐targeted AIE780‐A1811 nanoparticles self‐assemble via amide coupling of a mitochondria‐directed photosensitizer with the ADC SHR‐A1811. Upon 660 nm irradiation, they generate ROS, photothermal effects, and controlled drug release, inducing immunogenic pyroptosis and M2‐to‐M1 macrophage reprogramming. This dual action remodels the immunosuppressive

A lysosomal escape‐enabled endoplasmic reticulum‐targeting BODIPY photothermal agent for enhanced tumor ablation

open access: yesSmart Molecules, EarlyView.
To advance precision cancer therapy, we engineered ER‐BDP NPs, a self‐assembled nanomedicine designed for selective ER localization. By integrating organelle targeting with localized laser activation, this agent mediates precision‐guided tumor destruction in vitro and in vivo while reducing off‐target effects, effectively balancing therapeutic efficacy

Stimuli‐responsive nanostructured hydrogen sulfide donors for enhanced cancer treatments

open access: yesSmart Molecules, EarlyView.
Three typical kinds of stimuli‐responsive nanostructured hydrogen sulfide (H2S) donors are reviewed. The nanostructures ensure precise delivery of H2S to the lesion site and regulate the release behavior. The H2S‐based gas therapy has been used to synergize with other cancer treatment modalities, achieving enhanced efficacy while reducing side effects.

Photostabilized halocyanine for near‐infrared excited bimodal photothermal synergism and tumor‐targeted therapy

open access: yesSmart Molecules, EarlyView.
A series of halogenated organic small molecules were prepared by substituting hydrogen atoms in BC7 molecules with halogen atoms. These chemically modified derivatives displayed significantly improved stability, warming efficiency, and reactive oxygen species generation ability. BC7‐Br and BC7‐Cl showed remarkably enhanced therapeutic efficacy relative
