Dynamics of cardiac re-entry in micro-CT and serial histological sections based models of mammalian hearts [PDF]

open access: yesarXiv, 2018
Cardiac re-entry regime of self-organised abnormal synchronisation underlie dangerous arrhythmias and fatal fibrillation. Recent advances in the theory of dissipative vortices, experimental studies, and anatomically realistic computer simulations, elucidated the role of cardiac re-entry interaction with fine anatomical features in the heart, and ...

Verteporfin‐Mediated In Situ Nanovaccine Based on Local Conventional‐Dose Hypofractionated Radiotherapy Enhances Antitumor and Immunomodulatory Effect

open access: yesAdvanced Science, EarlyView.
Here gelatinase‐responsive methoxypolyethyleneglycol–PVGLIG–polycaprolactone (mPEG–PVGLIG–PCL) nanoparticles’ loading verteporfin (N@VP) is developed, enhancing radiotherapy via X‐ray‐triggered singlet oxygen generation. Combined with 2 Gy (gray, a radiation dose unit) irradiation, N@VP achieves antitumor efficacy comparable to 8 Gy, and also promotes ...

Venous thromboembolism - Expanding therapeutic options

open access: yesМедицинский совет, 2013
Venous thromboembolism (VTE) is caused by the formation of blood clots within a vein resulting in vein occlusion and risk of blood clots travelling to the pulmonary arteries.

CardiacNET: Segmentation of Left Atrium and Proximal Pulmonary Veins from MRI Using Multi-View CNN [PDF]

open access: yesarXiv, 2017
Anatomical and biophysical modeling of left atrium (LA) and proximal pulmonary veins (PPVs) is important for clinical management of several cardiac diseases. Magnetic resonance imaging (MRI) allows qualitative assessment of LA and PPVs through visualization.

GLS1‐Mediated Redundancy in Glutamate Accelerates Arterial Calcification via Activating NMDAR/Ca2+/β‐Catenin Pathway

open access: yesAdvanced Science, EarlyView.
GLS1 is a novel contributor to arterial calcification. GLS1‐catalyzed glutamate exerts the promoting effects on osteogenic reprogramming in arteries. NMDAR, a glutamate receptor, is also activated and overexpressed during arterial calcification.
