A woman's risk of dying from heart disease depends in part on geography, according to the first national study of heart disease in women by region, race, and ethnic origin. Women and Heart Disease: An Atlas of Racial and Ethnic Disparities in Mortality, released last month by the Centers ...
Human cardiovascular system - Heart Wall, Blood Flow, Circulation: The wall of the heart consists of three distinct layers—the epicardium (outer layer), the myocardium (middle layer), and the endocardium (inner layer). Coronary vessels supplying arteria
The heart is essentially a muscle(a little larger than the fist). Like any other muscle in the human body, it contracts and expands. Unlike skeletal muscles, however, the heart works on the "All -or-Nothing Law". That is, each time the heart contracts it does so with all its force....

Areas of application include medicine and the pharmaceutical industry. The invention aims to make methods available which are used to diagnose the expression of ALC-1. ...
In all four functions, two of these arguments indicate the camera position (labeled as EyePosition in the function template) and the UpDirection. The LookAt functions include a FocusPosition argument—a position the camera is pointed at—while the LookTo functions have an EyeDirection, which...
Congenital heart defects constitute the most common human birth defect, however understanding of how these disorders originate is limited by our ability to model the human heart accurately in vitro. Here we report a method to generate developmentally relevant human heart organoids by self-assembly usi...
最近,约翰斯顿又出了一本名为《人类心理字母表》的书,用26个字母代表26种“情绪毒药”,逐一解读并提出了对策。 Now Mathew and his lifelong friend and writer James Kerr have produced an equally enchanting and enlightening book, The Alphabet Of the Human Heart, chronicling the negative emotions that can...
The human heart develops through complex mechanisms producing morphological and functional changes during gestation. We have recently demonstrated using diffusion tensor MRI that over the relatively short space of 40 days, between 100–140 days gestation
In 2024, scientists used stem cells to grow mini human hearts in the lab. These replica hearts, which are smaller than a grain of rice, have blood vessels and all the cell types that are usually found in the human heart. They even beat like the real thing. Separately, researchers are ...
