Mechanisms of sudden cardiac death
Worldwide, sudden cardiac death (SCD) is a major problem. It is most frequently caused by ventricular tachyarrhythmias: Monomorphic and polymorphic ventricular tachycardia (VT), torsade de pointes (TdP), and ventricular fibrillation (VF).

Sudden death and sudden birth of entanglement in common structured reservoirs [PDF]
We study the exact entanglement dynamics of two qubits in a common structured reservoir. We demonstrate that, for certain classes of entangled states, entanglement sudden death occurs, while for certain initially factorized states, entanglement sudden birth takes place.

Multiscale studies of delayed afterdepolarizations I: A comparison of two biophysically realistic mathematical models for human ventricular myocytes [PDF]
Focal arrhythmias, which arise from delayed afterdepolarizations (DADs), are observed in various pathophysiological heart conditions; these can lead to sudden cardiac death. A clear understanding of the electrophysiological factors of cardiac myocytes, which lead to DADs, can suggest pharmacological targets that can eliminate DAD-induced arrhythmias ...

Hematoxylin–eosin (H&E) stains of the heart, liver, lung, and kidney show acute toxicity. Abstract Background To investigate the toxicity of N‐n‐butyl haloperidol iodide (F2), a quaternary ammonium salt derivative of haloperidol, in mice for potential therapeutic purposes. Methods The acute median lethal dose (LD50) of F2 was determined using the Bliss

Sudden cardiac death – Historical perspectives
Sudden cardiac death (SCD) is an unexpected death due to cardiac causes that occurs in a short time period (generally within 1 h of symptom onset) in a person with known or unknown cardiac disease.

Entanglement Sudden Death in Band Gaps [PDF]
Using the pseudomode method, we evaluate exactly time-dependent entanglement for two independent qubits, each coupled to a non-Markovian structured environment. Our results suggest a possible way to control entanglement sudden death by modifying the qubit-pseudomode detuning and the spectrum of the reservoirs.

Viral metagenomic analysis reveals potential biological hazards in non‐human primates in a zoo
The investigation identifies the presence of Encephalomyocarditis virus (EMCV), Baboon endogenous virus (BAV), Human endogenous retrovirus (HERV), and Baboon endogenous virus (BaEV) in non‐human primates (NHPs) at the Zoo, indicating potential zoonotic threats.

Novel Classification of Ischemic Heart Disease Using Artificial Neural Network [PDF]
Ischemic heart disease (IHD), particularly in its chronic stable form, is a subtle pathology due to its silent behavior before developing in unstable angina, myocardial infarction or sudden cardiac death. Machine learning techniques applied to parameters extracted form heart rate variability (HRV) signal seem to be a valuable support in the early ...

Objective Cardiovascular disease (CVD) is a leading cause of death in individuals with systemic lupus erythematosus (SLE). We assessed atherosclerotic plaque progression and incident cardiovascular events in patients with SLE over a 10‐year follow‐up.
