CO2 microbubble colloidal gas aphrons for EOR application: the generation using porous filter, diameter size analysis and gas blocking impact on sweep efficiency

Journal of Petroleum Exploration and Production Technology, 2019
The CO2 is regarded to be an excellent solvent for miscible flooding. However, it is still facing a main problem which is the high mobility. Microbubbles with their unique characters offer some advantages for CO2 EOR application.

Glutaminolysis Blockade‐Empowered Bimodal Nanodepot for Spatially Complementary Sono‐Thermal Ablation via PANoptosis and STING Activation Against Large Tumors

Advanced Science, EarlyView.
An injectable bimodal TCPD nanodepot disrupts glutaminolysis and TCA metabolism, sensitizing large tumors to spatially complementary sono‐thermal ablation for complete treatment coverage. This intervention induces mitochondrial and endoplasmic reticulum dysfunction, genotoxicity, and NAD+ depletion, converging to trigger PANoptosome assembly and ...

Complementary correlation between surface microbubble and droplet shapes

AIP Advances
Previous atomic force microscopy studies have suggested that surface micro- and nanobubbles exhibit a flat shape. In this study, we directly observed surface microbubbles formed in an NH3BH3 solution using an optical microscope. No flat microbubbles were

Low‐Intensity Ultrasound‐Triggered Microbubble Cavitation Attenuates Diabetic Kidney Injury Partially by Reversing Endothelial Dysfunction

Advanced Science, EarlyView.
Non‐invasive low‐intensity pulsed ultrasound ‐triggered cavitation of clinically approved diagnostic‐grade microbubbles delivers favorable mechanical stimuli to renal microvasculature. This intervention restores renal microvascular homeostasis, alleviates DKD‐associated histological and functional damage, and suppresses inflammatory and fibrotic ...

Surface contact of bound targeted microbubbles

, 2012
For molecular imaging using ultrasound contrast agents, targeted microbubbles are designed with specific ligands linked to the coated shell. Research is ongoing to determine the binding force of targeted microbubbles and to distinguish bound from unbound

Acoustically Activatable Drug‐Loaded Nanodroplets for Mechanochemical Therapy in Solid Tumors

Advanced Science, EarlyView.
Microfluidically fabricated drug‐loaded nanodroplets are sequentially activated by dual‐frequency ultrasound through acoustic droplet vaporization followed by bubble collapse, enabling spatially controlled drug release and mechanical tumor fractionation, resulting in synergistic mechanochemotherapy and prolonged survival.

Therapeutic potential of ultrasound microbubbles in gastrointestinal oncology: recent advances and future prospects

Therapeutic Advances in Gastroenterology, 2015
Microbubbles were initially invented as contrast agents for ultrasound imaging. However, lately more and more therapeutic applications of microbubbles are emerging, mostly related to drug and gene delivery.

NCOA4 Accelerates Abdominal Aortic Aneurysm Formation by Regulating Macrophage Activation and Ferroptosis via STAT1–CH25H Axis

Advanced Science, EarlyView.
Under pathological stimulation, NCOA4 in macrophages interacts with STAT1 to promote CH25H transcription. The subsequent increase in 25‐HC production activates macrophages, triggers inflammatory responses and ferroptosis, and accelerates the progression of AAA.

Magnetic resonance imaging of oxygen microbubbles

Healthcare Technology Letters, 2019
Oxygen loaded microbubbles are being investigated as a means of reducing tumour hypoxia in order to improve response to cancer therapy. To optimise this approach, it is desirable to be able to measure changes in tissue oxygenation in real-time during ...

Inhibition of MEKK3 Prevents Cerebral Cavernous Malformation Progression Via Restoring Endothelial Integrity and Restricting Microglial Activation

Advanced Science, EarlyView.
In this study, we demonstrate that aberrant MEKK3 signaling in endothelial cells and microglia drives the progression of cerebral cavernous malformations (CCMs). Furthermore, we identify DPDH as a potent small‐molecule MEKK3 inhibitor with substantial therapeutic potential for CCM treatment.
