Crt (genetics)

CRT is the gene cluster responsible for the biosynthesis of carotenoids. Those genes are found in eubacteria, in algae and are cryptic in Streptomyces griseus.

Genetics

Genetics is the study of genes, heredity, and genetic variation in living organisms. It is generally considered a field of biology, but it intersects frequently with many of the life sciences and is strongly linked with the study of information systems.

The father of genetics is Gregor Mendel, a late 19th-century scientist and Augustinian friar. Mendel studied 'trait inheritance', patterns in the way traits were handed down from parents to offspring. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene.

Trait inheritance and molecular inheritance mechanisms of genes are still a primary principle of genetics in the 21st century, but modern genetics has expanded beyond inheritance to studying the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance) and within the context of a population. Genetics has given rise to a number of sub-fields including epigenetics and population genetics. Organisms studied within the broad field span the domain of life, including bacteria, plants, animals, and humans.

Genetics (journal)

Genetics is a monthly scientific journal publishing investigations bearing on heredity, genetics, biochemistry and molecular biology. Genetics is published by the Genetics Society of America. It has a delayed open access policy, and makes articles available online without a subscription after 12 months have elapsed since first publication. Since 2010, it is published online-only.George Harrison Shull was the founding editor of Genetics in 1916. Its 2014 impact factor is 5.963.

Genetic relationship (linguistics)

In linguistics, genetic relationship is the usual term for the relationship which exists between languages that are members of the same language family. The term genealogical relationship is sometimes used to avoid confusion with the unrelated use of the term in biological genetics. Languages that possess genetic ties with one another belong to the same linguistic grouping, known as a language family. These ties are established through use of the comparative method of linguistic analysis.

Two languages are considered to be genetically related if one is descended from the other or if both are descended from a common ancestor. For example, Italian is descended from Latin. Italian and Latin are therefore said to be genetically related. Spanish is also descended from Latin. Therefore, Spanish and Italian are genetically related. In a similar way, Swedish and Norwegian are genetically related through the North Germanic branch of the Indo-European language family.

Cardiac resynchronization therapy

An implanted cardiac resynchronization device is a medical device used in cardiac resynchronization therapy (CRT). It resynchronizes the contractions of the heart’s ventricles by sending tiny electrical impulses to the heart muscle, which can help the heart pump blood throughout the body more efficiently. CRT defibrillators (CRT-D) also incorporate the additional function of an implantable cardioverter-defibrillator, to quickly terminate an abnormally fast, life-threatening heart rhythm. CRT and CRT-D have become increasingly important therapeutic options for patients with moderate and severe heart failure.

Cardiac resynchronization therapy in heart failure

Cardiac resynchronization therapy (CRT) is an effective therapy in patients with heart failure and dyssynchrony identified as a prolonged QRS duration. Benefits include improved exercise tolerance, reduced remodeling (reduction in LV chamber size and measures of mitral regurgitation), reduced mortality, and need for hospitalization in patients in sinus rhythm.
