Bioabsorbable Endovascular Adhesive Tape (BEAT) for Improving Vascular Regeneration

Advanced Science, EarlyView.
A bioabsorbable endovascular adhesive tape (BEAT) platform based on a hierarchical polyelectrolyte complex is developed to enhance drug delivery in the DCB system. The coating enables rapid transfer to the vessel, provides short‐term mechanical support, and promotes both immediate transfer and long‐term retention of drugs at the lesion site.

Cosmic evolution of the CIV in high-resolution hydrodynamic simulations [PDF]

, 2010
We investigate the properties of triply ionized Carbon (CIV) in the Intergalactic Medium using a set of high-resolution and large box-size cosmological hydrodynamic simulations of a $\Lambda$CDM model.

Colour Doppler imaging in Takayasu's arteritis [PDF]

British Journal of Ophthalmology, 1998
Editor,—Takayasu’s arteritis (TA) is a systemic necrotising vasculitis of unknown aetiology whose characteristic ocular manifestations relate to ocular ischaemia. Orbital colour Doppler imaging (CDI) is useful to evaluate haemodynamics of the orbital circulation and its abnormalities.1 We report the ophthalmic artery blood flow in two patients with TA ...

A Bioinstructive Injectable Hydrogel for Enhancing Intrinsic Regeneration through Cell Recruitment and Training

Advanced Science, EarlyView.
A bioinstructive injectable hydrogel enables sustained release of stromal cell–derived factor‐1 alpha (SDF‐1α) and stable retention of laminin through ionic and hydrophobic interactions. This dual‐signaling matrix promotes endogenous stem cell recruitment and training, supports angiogenesis, and enhances intrinsic regenerative processes in ischemic ...

Measurements of left ventricular myocardial longitudinal systolic displacement using spectral and colour tissue Doppler: time for a reassessment?

Cardiovascular Ultrasound, 2009
Background Echocardiographic measurements of left ventricular (LV) myocardial displacement may produce different results depending on the choice of employed modality and subjective adjustments during data acquisition and analysis.

Magnetic Reconnection resulting from Flux Emergence: Implications for Jet Formation in the lower solar atmosphere? [PDF]

, 2011
We aim at investigating the formation of jet-like features in the lower solar atmosphere, e.g. chromosphere and transition region, as a result of magnetic reconnection.

Data‐Driven Feedback Identifies Focused Ultrasound Exposure Regimens for Improved Nanotheranostic Targeting of the Brain

Advanced Science, EarlyView.
Machine learning models predict in real time the onset of harmful microbubble collapse during microbubble‐enhanced focused ultrasound (MB‐FUS) and enable dynamic adjustment of sonication to prevent cavitation‐induced damage. This predictive control expands the safe operating window for bloodbrain barrier opening, enhancing nanoparticle delivery and ...

Kinematics of massive star ejecta in the Milky Way as traced by $^26$Al [PDF]

, 2013
Context. Massive stars form in groups and their winds and supernova explosions create superbubbles up to kpc in size. The fate of their ejecta is of vital importance for the dynamics of the interstellar medium, for chemical evolution models, and the ...

Three-dimensional echocardiography of colour Doppler flow

Archives of Cardiovascular Diseases, 2010
Three-dimensional echocardiography of colour Doppler flow developed quickly with the advent of three-dimensional echocardiography. An increasing amount of research has shown that three-dimensional echocardiography of colour Doppler flow is feasible and facilitates measurement of stroke volume and cardiac output, and assessment of heart valve and ...

Amelioration of Post‐Stroke Edema and Microcirculatory Dysfunction via Targeted AQP4 Inhibition While Preserving the Glymphatic System

Advanced Science, EarlyView.
Compared to untargeted therapy, the targeted nanocarrier, Angiopep‐2‐conjugated Lipid Nanoparticle (A‐LNP) loaded with TGN‐020 (TGN), selectively accumulated in stroke‐injured regions. It suppressed local aquaporin‐4 (AQP4) overexpression, thereby alleviating cerebral edema and hypoperfusion while preserving global glymphatic clearance.
