"Diastology" Natural Recordings by Native Speakers
Diastology is the study of the internal flow of the blood through the heart, particularly during diastole, the relaxation phase of the cardiac cycle. It is a branch of cardiology that focuses on the dynamics of blood flow within the heart chambers, including the pumping action of the heart and the resistance of the blood vessels. Diastology is used to diagnose and treat various heart conditions, such as heart failure, cardiac arrhythmias, and valvular heart disease.

Diastereoisomers are stereoisomers that are not mirror images of each other, unlike enantiomers. They have a different three-dimensional arrangement of atoms in space, but are not non-superimposable mirror images. This means that diastereoisomers can rotate plane-polarized light, but by different amounts, and can have different physical and chemical properties. Diastereoisomers are also chirotopic, meaning their stereochemistry is related to the presence of asymmetric centers, such as chirality centers (optically active centers) or planar chirality centers.
Diastereomers are stereoisomers that are not mirror images of each other, but have a different three-dimensional shape. They are molecules that have the same chemical formula and sequence of atoms, but differ in the arrangement of atoms in three-dimensional space. Diastereomers are chiral molecules, meaning they have a non-superimposable mirror image, but they cannot be superimposed onto their mirror image. This means that diastereomers have different physical and chemical properties, such as melting points, boiling points, and solubility.
Diastratic refers to a type of sedimentary rock that is composed of sediment of several different origins, such as clay, silt, and sand, which have been deposited together in a non-specific order.
Diastrophic refers to a severe or catastrophic situation, often used to describe a disaster or a crisis of great magnitude. It can also describe a turning point or a sudden and significant change, often with negative consequences.
Diasystem is a term used in linguistics that refers to a system of interconnected concepts, ideas, or structures that are related to each other within a language. It can also refer to a system of rules or patterns that govern the organization of a language, such as the way words are ordered to form sentences.
The Diatessaron is a early Christian gospel harmony written by Tatian in the 2nd century AD. It is a book that combines the four canonical Gospels of Matthew, Mark, Luke, and John into a single narrative, aiming to present a unified account of Jesus' life, teachings, and ministry.
