[Nature and histogenesis of pulmonary sclerosing hemangioma]

The presentation of detailed methods for the evaluation of right ventricle function will enhance the quality and reliability of pulmonary hypertension research, offering a robust framework for future studies and enhancing reproducibility across different...

Presented here is a protocol to investigate the effects of home-based prescribed pulmonary exercise in stable chronic obstructive pulmonary disease (COPD) patients, which is modified based on traditional Chinese exercises according to dyspnea and limited exercise capacity observed in COPD...

The following protocol describes the methodology for the acquisition and analysis of echocardiographic images used to obtain the Left Atrial Volume (LAV), Aorta (Ao) diameter, and Pulmonary Artery (PA) diameter in mice. This technique is a non-invasive, non-terminal procedure that allows assessment of the cardiopulmonary...

Marginating-pulmonary leukocytes exhibit unique characteristics and distinct immunological functions compared to other leukocyte populations. Here we describe selective harvesting of this subpopulation of pulmonary leukocytes, by forced perfusion of the lungs in rats and mice. Marginating-pulmonary leukocytes seem critical in determining susceptibility to blood-borne and lung-related...

Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...
