Therapeutic Applications of Stimuli‐Based Release and Engineering of Extracellular Vesicles

Advanced NanoBiomed Research, EarlyView.
This review summarizes the effects of endogenous and exogenous stimuli, their effects on the natural release of extracellular vesicles, as well as their uptake and release. It also gives an overview of stimuli‐responsive EVs and their therapeutic applications. Extracellular vesicles (EVs), nano‐ to microsized lipid bilayer membrane‐bound particles, are

Displacement monitoring performance of relative positioning and Precise Point Positioning (PPP) methods using simulation apparatus

Advances in Space Research, 2019
Abstract Besides the classical geodetic methods, GPS (Global Positioning System) based positioning methods are widely used for monitoring crustal, structural, ground etc., deformations in recent years. Currently, two main GPS positioning methods are used: Relative and Precise Point Positioning (PPP) methods.

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy

BMEMat, EarlyView.
Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

Digital Transformation and Informal Innovation in Africa: Reframing STI Policy for Inclusive Circular Economy Transitions

Business Strategy and the Environment, EarlyView.
ABSTRACT Amid increasing environmental and economic pressures, Africa's transition to a circular economy (CE) presents a vital pathway to inclusive, low‐carbon development. Yet, how digital transformation, informal innovation, and science, technology, and innovation (STI) policy readiness shape CE outcomes remains underexplored.
