Dispersion of ventricular repolarization

, 1997
After a century of use, the electrocardiogram (ECG) remains a standard non-invasive technique for the clinical diagnosis of cardiac abnormalities. The ECG provides considerable information about the anatomy and the physiology of the heart.

An Injectable ROS‐Responsive Nanozyme Hydrogel Regulates the Uterine Microenvironment to Prevent Intrauterine Adhesions

Advanced Science, EarlyView.
The injectable CeTA@GPP hydrogel is administered via intrauterine injection, forming a protective barrier. In the high ROS inflammatory microenvironment of injured endometrium, boronate ester cleavage triggers responsive CeTA release and local enrichment.

An Injectable Metal‐Drug Supramolecular Condensate Enables Radiosensitization and Systemic Antitumor Immunity for Post‐Surgical Osteosarcoma Therapy

Advanced Science, EarlyView.
This work designed an injectable metal‐drug supramolecular condensate formed from hafnium ions and alendronate (Hf‐ALN) and loaded with the COX‐2 inhibitor celecoxib (CXB) for synergistic radioimmunotherapy of postoperative osteosarcoma. Mechanistically, upon X‐ray irradiation, Hf enhances radiation energy deposition, ROS generation, and DNA damage ...

A CD14‐Targeting In Situ Hydrogel Directs Macrophage Reprogramming to Minimize Scar Formation

Advanced Science, EarlyView.
A CD14‐targeting in situ hydrogel formed from a microbial polysaccharide rapidly remodels the immune microenvironment by reprogramming macrophage polarization, suppressing excessive inflammation, and coordinating tissue regeneration. This multifunctional hydrogel promotes scar‐reduced wound repair through enhanced angiogenesis, collagen remodeling, and

Ajmaline attenuates electrocardiogram characteristics of inferolateral early repolarization.

, 2012
J waves are the hallmark of both inferolateral early repolarization (ER) and Brugada syndrome. While ajmaline, a class 1a antiarrhythmic drug, accentuates the J wave in Brugada syndrome, its effect on ER is unreported.Journal Articleinfo:eu-repo ...

Ultrasound‐Activated Nanoinhibitors Blocking the Chemo‐Immune Checkpoint to Overcome Chemotherapy‐Induced Immune Resistance

Advanced Science, EarlyView.
A sono‐responsive chemo‐immune checkpoint nanoinhibitor (Sono‐TT8) co‐delivering TPZ chemotherapy and siXkr8 simultaneously kills tumor cells and blocks PS externalization, reversing chemotherapy‐induced immunosuppression and enhancing antitumor immunity. ABSTRACT Breast cancer features an immunosuppressive tumor microenvironment following chemotherapy

Sequence and dispersion of repolarization of the right atrium: Implications of repolarization disturbance in atrial fibrillation

, 2004
To explore the global sequence and dispersion of repolarization of the right atrium, monophasic action potentials (MAPs) were sequentially recorded from the right atrium using an electroanatomical mapping (CARTO) system in 10 healthy pigs and in 10 ...
