For example, at the Council of Nicea (325) the word hypostasis was equated with ousia (essence) and was translated in Latin as substantia (substance)(DS 126), yet in 451 the Council of Chalcedon distinguished hypostasis from physis, the equivalent of ousia, as person from nature, or substance (DS 301 - 02).

For it has nothing to do with the verb «to be,» and derives rather from the Latin, «substantia», denoting something «standing under» another, although, as we shall see, this is in a crucial sense not what Aristotle meant by ousia!
It was, however, by his logical works that Aristotle first became widely known to the Western world, so that the Boethian logical term, «substantia», stuck (DBAM 68).
So, said the old theologians, God is one «substantia,» one essence and being, but in Christian experience he appears in three «personae,» plays three parts, unveils himself to his children in three characters — Father - Creator; Christ the Revealer; the Spirit, our indwelling Friend and Comforter.
Under the proposed law, called the Made in America Act, businesses that contract with the county would have to guarantee that the goods or materials they provide are manufactured or produced «in whole, or in substantia...
These symptoms arise because nerve cells producing the neurotransmitter dopamine, located in an area of the brain known as the substantia nigra, slowly die.
In a three - stage meta - analysis, Harvard University neurologist Clemens Scherzer and his collaborators analyzed gene expression in 410 samples taken from patients that either had symptomatic or asymptomatic Parkinson's or were healthy, including 185 samples of substantia nigra — a midbrain region where dopamine neurons are particularly susceptible to degeneration.
The symptoms of Parkinson's — which is characterized by stiffness and can lead to a loss of motor and speech function — are triggered by the progressive death of neurons in a midbrain region called the substantia nigra that produce the neurotransmitter dopamine (implicated in the pleasure and reward systems as well as in the maintenance of proper movement control).
Researchers observed a 50 percent loss of cells when they injected normal mice with an agent that selectively kills dopamine neurons of the substantia nigra (to emulate Parkinson's) semiweekly for five weeks.

The researchers hypothesize that, in the case of Parkinson's, these calcium ions are not properly sequestered or ferried out of the substantia nigra neurons, making those cells possibly more vulnerable to toxins.
Their analysis focused on the substantia nigra, a brain structure where Parkinson's disease kills neurons that use the chemical dopamine to communicate with other cells.
Parkinson's disease destroys dopamine - producing cells in the substantia nigra, which connect to adjacent brain areas.

Even more surprisingly, the researchers observed that areas of the brain, the globus pallidus and the substantia nigra, which participate in the reward circuit (activated when we love something), were more involved in people who do not like cheese than in those who do.
That's because the movement problems and other symptoms of the disease are caused by the death of neurons, located in a part of the brain called the substantia nigra, that produce the neurotransmitter dopamine.
Last year, the same researchers showed that the trigger came from cells in a structure in the embryonic brain called the floor plate, which dopamine cells brush past while migrating to their eventual home in a part of the brain called the substantia nigra.
