Mild Hypothermia via External Cooling Improves Lung Function and Alleviates Pulmonary Inflammatory Response and Damage in Two-Hit Rabbit Model of Acute Lung Injury.

Objectives: Targeted temperature management (TTM) with therapeutic hypothermia (TH) has an organ-protective effect by mainly reducing inflammatory response. Here, our objective was to determine, for the first time, whether mild TH with external cooling, a simple and inexpensive method, could be safe or even beneficial in two-hit rabbit model of acute lung injury/acute respiratory distress syndrome (ALI/ARDS).

Methods: Twenty-two New Zealand rabbits (6-month-old) were randomly divided into healthy control (HC) with conventional ventilation, but without injury, model group (ALI), and hypothermia group with external cooling (ALI-HT).

Mesenchymal stem cells derived from epicardial adipose tissue reverse cardiac remodeling in a rabbit model of myocardial infarction.

Objective: Myocardial infarction (MI) is one of the most important causes of death. MI-related tissue loss and cardiac remodeling may result in heart failure. Intramyocardial injection of mesenchymal stem cells derived from adipose tissues, in acute MI animal models, has shown promising regenerative capabilities.

The Proportion of SARS-CoV-2 Infections That Are Asymptomatic : A Systematic Review.

Background: Asymptomatic infection seems to be a notable feature of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the pathogen that causes coronavirus disease 2019 (COVID-19), but the prevalence is uncertain.

Purpose: To estimate the proportion of persons infected with SARS-CoV-2 who never develop symptoms.
