Physiology

Factor X is synthesized in the liver and requires vitamin K for its synthesis.

Factor X is activated into factor Xa by both factor IX (with its cofactor, factor VIII in a complex known as intrinsic Xase) and factor VII with its cofactor, tissue factor (a complex known as extrinsic Xase). It is therefore the first member of the final common pathway or thrombin pathway.

It acts by cleaving prothrombin in two places (an arg-thr and then an arg-ile bond), which yields the active thrombin. This process requires factor V as a cofactor.

Factor Xa is inactivated by protein Z-dependent protease inhibitor (ZPI), a serine protease inhibitor (serpin). The affinity of this protein for factor Xa is increased 1000-fold by the presence of protein Z, while it does not require protein Z for inactivation of factor XI. Defects in protein Z lead to increased factor Xa activity and a propensity for thrombosis.

The half life of factor X is 40-45 hours.

Genetics

The human factor X gene is located on the thirteenth chromosome (13q34).

Role in disease

Inborn deficiency of factor X is very uncommon (1:500,000), and may present with epistaxis (nosebleeds), hemarthrosis (bleeding into joints) and gastrointestinal blood loss. Apart from congenital deficiency, low factor X levels may occur occasionally in a number of disease states.

Deficiency of vitamin K or antagonism by warfarin (or similar medication) leads to the production of an inactive factor X. In warfarin therapy, this is desirable to prevent thrombosis.

Therapeutic use

Factor X is not commercially available as a concentrate, but is part of fresh frozen plasma and prothrombin complex.

History

American and British scientists described deficiency of factor X independently in 1953 and 1956, respectively. As with some other coagulation factors, the factor was initially named after these patients, a Mr Rufus Stuart and a Miss Audrey Prower.

On April 1, 1889, with the establishment of the modern municipality system, several villages merged to form Higashimurayama Village (Higashimurayama-mura). On April 1, 1942, it became Higashimurayama Town (Higashimurayama-machi), and on April 1, 1964, it became a city. Hachikokuyama park is in Higashimurayama.

MEDR is actually a theoretical measure of the amount of data throughput a line can handle, but does not necessarily refer to the amount of data available to the customer at the end of said copper wiring. The data throughput that can actually be presented to the end user is measured by AIDR or As Is Data Rate.

MEDR automatically assumes that the copper wiring in question is groomed to the best available capacity and needs no further work and is an optimistic estimate of what can be achieved over the wire.

It is an extremely cold-hardy grape that is self-fertile. This variety is grown successfully in Finland and was widely planted in Minnesota in the early 20th century. It ripens in late September in New York State. It bears dark, blue-black fruit that is used for jellies, fruit juices, etc. but rarely for wine.

Beta was released by Louis Suelter, and named for his wife. Because of this, the proper pronunciation is actually “Bett-uh”, but the name is more commonly assumed to follow the pronunciation of the Greek letter.

Suelter released a number of other cultivars from the same cross, including the equally hardy Suelter grape.
