Serre duality
Serre duality, or Serre's duality theorem, is a duality theorem in algebraic geometry, proved by Jean-Pierre Serre in 1955, that identifies top cohomology with duals of Hom groups.
Serre spectral sequence
The Serre spectral sequence, also called the Leray–Serre spectral sequence, computes the homology of a fibration's total space from the homology of its base and fiber.
Serre's multiplicity conjectures
Serre's multiplicity conjectures are statements in commutative algebra about Serre's Tor-formula intersection multiplicity, defined in the late 1950s; nonnegativity and vanishing are proved, positivity remains open.
Serreion Teichos/Ganos
Serreion Teichos/Ganos (Σέρρειον τεῖχος, Γάνος), an ancient fortified settlement on the northwest Propontis coast in Tekirdağ, Turkey, near Gaziköy; attested from Alcibiades' era and Xenophon's Anabasis, conquered by Philip II, later a major Byzantine wine and amphora production center.

Sertindole
Sertindole (Serdolect) is an atypical antipsychotic for schizophrenia, authorized in Europe in 1996, suspended in 1999 over cardiac death concerns, and reintroduced in 2002 with ECG monitoring; it blocks HERG channels and prolongs QTc about 20 ms.
Sertoli cell
Sertoli cell (nurse cell of the testis): somatic support cell of seminiferous tubules discovered by Enrico Sertoli in 1865; nourishes germ cells, forms the blood-testis barrier, secretes AMH, androgen-binding protein, and GDNF, and is the testis's most age-sensitive cell type.
Sertraline
Sertraline (Zoloft, Lustral) is an SSRI antidepressant by Pfizer, US-approved for depression in 1991 and later OCD, panic disorder, and PTSD; Cochrane evidence shows a trend favoring it over other antidepressants.
