Cardiac arrest (CA) is a life-threatening condition that requires immediate medical attention. Considerable advances in resuscitation have led to an increasing number of patients who survive the initial arrest event. However, among this growing patient population, morbidity and mortality rates remain strikingly high.

Captive, pelagic red crabs (Pleuroncodes planipes) had shortened lifespans and cutaneous black spots. Histologically, epidermal and mesenchymal cells had 3-5 µm diameter intranuclear inclusions, necrosis, vacuolation, and/or hyperplasia. The remaining organs were histologically unremarkable.

Article Synopsis
  • Microplastics (MPs) were found in significant amounts in both sediments and surface water of the River Basantar, with mean abundances of 3 items/g for sediments and 530 items/L for surface water.
  • The common types of MPs identified included fragments, fibers, and films, with polymer types such as polyethylene and polypropylene, indicating a concerning level of pollution.
  • Risk assessments showed that all sites were classified under "very high" pollution risk, primarily due to urbanization and human activities, highlighting the urgent need for further research and coordinated efforts to combat plastic pollution in freshwater ecosystems.

We consider an analytically tractable model that exhibits the main features of the Page curve characterizing the evolution of entanglement entropy during evaporation of a black hole. Our model is a gas of noninteracting fermions on a lattice that is released from a box into the vacuum. More precisely, our Hamiltonian is a tight-binding model with a defect at the junction between the filled box and the vacuum.

Background: Hypertension (HTN) is a medical condition characterized by persistent systolic and diastolic blood pressures of ≥ 140 mmHg and ≥ 90 mmHg, respectively. With more than 1200 million adult patients aged 30-79 years worldwide according to the latest WHO data, HTN is a major health risk factor; more importantly, 46% of patients are unaware of this condition. Essential hypertension (EH), also known as primary hypertension, is the predominant subtype and has a complex etiology that involves both genetic and non-genetic factors.
