Swiss 3T3 Cells
|
D041701 |

Switzerland
|
D013557 |
[A country in Europe. It is bordered by Austria, France, Italy, Liechtenstein, and Germany. The capital is Bern.

Sydnones
|
D013558 |
[OXADIAZOLES bearing an oxygen at the 5-position. They are mesoionic, with delocalized positive and negative charges.

|
Syk Kinase
|
D000072377 |
[An SH2 domain-containing non-receptor tyrosine kinase that regulates signal transduction downstream of a variety of receptors including B-CELL ANTIGEN RECEPTORS. It functions in both INNATE IMMUNITY and ADAPTIVE IMMUNITY and also mediates signaling in CELL ADHESION; OSTEOGENESIS; PLATELET ACTIVATION; and vascular development.

Symbiosis
|
D013559 |
[The relationship between two different species of organisms that are interdependent; each gains benefits from the other or a relationship between different species where both of the organisms in question benefit from the presence of the other.
, A form of symbiosis between two organisms of different species in which one of them benefits from the association whereas the other is largely unaffected or not significantly harmed or benefiting from the relationship.

Symbolic Interactionism
|
D000073624 |
[Theoretical approach to social processes with a fundamental concern with power phenomena. There is a focus on the analysis of culture, the influence of Foucault, and the development of feminist perspectives.

Symbolism
|
D013561 |
[A concept that stands for or suggests something else by reason of its relationship, association, convention, or resemblance. The symbolism may be mental or a visible sign or representation. (From Webster, 3d ed)

Sympathectomy
|
D013562 |
[The removal or interruption of some part of the sympathetic nervous system for therapeutic or research purposes.
] |
|
Sympathectomy, Chemical
|
D013563 |
[Sympathectomy using chemicals (e.g., 6-hydroxydopamine or guanethidine) which selectively and reversibly destroy adrenergic nerve endings while leaving cholinergic nerve endings intact.
] |
|
Sympathetic Fibers, Postganglionic
|
D017779 |
[Nerve fibers which project from sympathetic ganglia to synapses on target organs. Sympathetic postganglionic fibers use norepinephrine as transmitter, except for those innervating eccrine sweat glands (and possibly some blood vessels) which use acetylcholine. They may also release peptide cotransmitters.
] |
|
Sympathetic Nervous System
|
D013564 |
[The thoracolumbar division of the autonomic nervous system. Sympathetic preganglionic fibers originate in neurons of the intermediolateral column of the spinal cord and project to the paravertebral and prevertebral ganglia, which in turn project to target organs. The sympathetic nervous system mediates the body's response to stressful situations, i.e., the fight or flight reactions. It often acts reciprocally to the parasympathetic system.

|
Sympathoadrenal System
|
D000084602 |
[A collection of the SYMPATHETIC NERVOUS SYSTEM and the ADRENAL MEDULLA of the ADRENAL GLANDS. Intra-adrenal connection from the medulla to the cortex connects the system to other neuroendocrine systems, which in concert participate in FLIGHT REACTION in stress situations. CATECHOLAMINES are the principle hormone in the system.

|
Sympatholytics
|
D013565 |
[Drugs that inhibit the actions of the sympathetic nervous system by any mechanism. The most common of these are the ADRENERGIC ANTAGONISTS and drugs that deplete norepinephrine or reduce the release of transmitters from adrenergic postganglionic terminals (see ADRENERGIC AGENTS). Drugs that act in the central nervous system to reduce sympathetic activity (e.g., centrally acting alpha-2 adrenergic agonists, see ADRENERGIC ALPHA-AGONISTS) are included here.
] |
|
Sympathomimetics
|
D013566 |
[Drugs that mimic the effects of stimulating postganglionic adrenergic sympathetic nerves. Included here are drugs that directly stimulate adrenergic receptors and drugs that act indirectly by provoking the release of adrenergic transmitters.

|
Sympatry
|
D061350 |
[In evolutionary theory, overlapping geographic distribution of diverging species. In sympatric GENETIC SPECIATION, genetic diversion occurs without geographic separation.
] |
|
Symphoricarpos
|
D031240 |
[A plant genus of the family CAPRIFOLIACEAE. The common name of "snowberry" is also used for GAULTHERIA.
] |
|
Symphysiotomy
|
D013567 |
[Surgical procedure to widen a woman's pelvis during childbirth.
] |
|
Symporters
|
D027981 |
[Membrane transporters that co-transport two or more dissimilar molecules in the same direction across a membrane. Usually the transport of one ion or molecule is against its electrochemical gradient and is "powered" by the movement of another ion or molecule with its electrochemical gradient.

|
Symptom Assessment
|
D063189 |
[Evaluation of manifestations of disease.
] |
|
Symptom Flare Up
|
D000067251 |
[A transient exacerbation of symptoms of an existing disease or condition.
