The substantia nigra (SN) is a basal ganglia structure located in the midbrain that plays an important role in reward and movement. Substantia nigra is Latin for "black substance", reflecting the fact that parts of the substantia nigra appear darker than neighboring areas due to high levels of neuromelanin in dopaminergic neurons. It was discovered in 1784 by Félix Vicq-d'Azyr, and Samuel Thomas von Sömmerring alluded to this structure in 1791. Parkinson's disease is characterized by the loss of dopaminergic neurons in the substantia nigra pars compacta.
Yareta or llareta is a flowering plant in the family Apiaceae native to South America. It grows in the Puna grasslands of the Andes in Peru, Bolivia, northern Chile, and western Argentina at altitudes between 3,200 and 5,200 metres.
Blood Work is a 2002 American mystery thriller film produced, directed by, and starring Clint Eastwood. The film co-stars Jeff Daniels, Wanda De Jesús, and Anjelica Huston. It is based on the novel of the same name by Michael Connelly.
The pars compacta is a portion of the substantia nigra, located in the midbrain. It is formed by dopaminergic neurons and located medial to pars reticulata. Parkinson's disease is characterized by the death of dopaminergic neurons in this region.

In mathematics, the Farrell–Markushevich theorem, proved independently by O. J. Farrell (1899–1981) and A. I. Markushevich (1908–1979) in 1934, is a result concerning the approximation in mean square of holomorphic functions on a bounded open set in the complex plane by complex polynomials. It states that complex polynomials form a dense subspace of the Bergman space of a domain bounded by a simple closed Jordan curve. The Gram–Schmidt process can be used to construct an orthonormal basis in the Bergman space and hence an explicit form of the Bergman kernel, which in turn yields an explicit Riemann mapping function for the domain.
Crossotini is a tribe of longhorn beetles of the Lamiinae subfamily. It was described by Thomson in 1864.
Tragocephalini is a tribe of longhorn beetles of the Lamiinae subfamily. It was described by Thomson in 1857.
Graciella is a genus of longhorn beetles of the subfamily Lamiinae, containing the following species:
Fonsecaea compacta is a saprophytic fungal species found in the family Herpotrichiellaceae. It is a rare etiological agent of chromoblastomycosis, with low rates of correspondence observed from reports. The main active components of F. compacta are glycolipids, yet very little is known about its composition. F. compacta is widely regarded as a dysplastic variety of Fonsecaea pedrosoi, its morphological precursor. The genus Fonsecaea presently contains two species, F. pedrosoi and F. compacta. Over 100 strains of F. pedrosoi have been isolated but only two of F. compacta.
Coptosia compacta is a species of beetle in the family Cerambycidae. It was described by Ménétriés in 1832, originally under the genus Saperda. It is known from Israel, Iran, Syria, Armenia, Jordan, and Turkey.
Graciella circulum is a species of beetle in the family Cerambycidae. It was described by Báguena in 1952.
Graciella epipleuralis is a species of beetle in the family Cerambycidae. It was described by Stephan von Breuning in 1950. It is known from Cameroon.
Graciella moea is a species of beetle in the family Cerambycidae. It was described by Jordan in 1903.
Graciella pulchella is a species of beetle in the family Cerambycidae. It was described by Klug in 1835, originally under the genus Saperda. It has a wide distribution in Africa. It feeds on Theobroma cacao.
Stenoporpia graciella is a species of geometrid moth in the family Geometridae. It is found in North America.
