All individuals in MeSH

Label Id Description
Sigmoidoscopy D012812 [Endoscopic examination, therapy or surgery of the sigmoid flexure. ]
Sign Language D012813 [A system of hand gestures used for communication by the deaf or by people speaking different languages. ]
Signal Detection, Psychological D017603 [Psychophysical technique that permits the estimation of the bias of the observer as well as detectability of the signal (i.e., stimulus) in any sensory modality. (From APA, Thesaurus of Psychological Index Terms, 8th ed.) ]
Signal Processing, Computer-Assisted D012815 [Computer-assisted processing of electric, ultrasonic, or electronic signals to interpret function and activity. ]
Signal Recognition Particle D018271 [A cytosolic ribonucleoprotein complex that acts to induce elongation arrest of nascent presecretory and membrane proteins until the ribosome becomes associated with the rough endoplasmic reticulum. It consists of a 7S RNA and at least six polypeptide subunits (relative molecular masses 9, 14, 19, 54, 68, and 72K). ]
Signal Transduction D015398 [The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway. ]
Signal-To-Noise Ratio D059629 [The comparison of the quantity of meaningful data to the irrelevant or incorrect data. ]
Signaling Lymphocytic Activation Molecule Associated Protein D000071179 [A signal transducing adaptor protein that contains a single SH2 DOMAIN and is essential for the regulation of SLAM FAMILY RECEPTORS in the immune response. Mutations in the SLAM-associated protein gene have been identified in cases of X-LINKED LYMPHOPROLIFERATIVE DISEASE. ]
Signaling Lymphocytic Activation Molecule Family D000071176 [Type-I membrane glycoproteins that are expressed primarily on the surface of CD4 or CD8-positive T-CELLS; NATURAL KILLER CELLS; and some populations of B CELLS. They are characterized by an N-terminal, extracellular IMMUNOGLOBULIN-LIKE DOMAIN and a membrane-proximal IMMUNOGLOBULIN C2-SET DOMAIN. SLAMF receptors typically signal through homophilic interactions and are important for mediating the immune response and immune cell differentiation. ]
Signaling Lymphocytic Activation Molecule Family Member 1 D000071177 [A 70-kDa SLAM family receptor that consists of an extracellular IMMUNOGLOBULIN-LIKE DOMAIN and an IMMUNOGLOBULIN C2-SET DOMAIN. It is expressed primarily by THYMOCYTES and activated T-LYMPHOCYTES, as well as by MACROPHAGES and DENDRITIC CELLS. It binds SLAMF1 receptors on other cells to mediate T-cell maturation and proliferation. It is also a receptor for the MEASLES VIRUS. ]
Signs and Symptoms D012816 [Clinical manifestations that can be either objective when observed by a physician, or subjective when perceived by the patient. ]
Signs and Symptoms, Digestive D012817 [Digestive system manifestations of diseases of the gastrointestinal system or of other organs. ]
Signs and Symptoms, Respiratory D012818 [Respiratory system manifestations of diseases of the respiratory tract or of other organs. ]
Sikkim D012819 [A state within northeast India in the Eastern Himalayas. The capital is Gangtok. ]
Silage D012820 [Fodder converted into succulent feed for livestock through processes of anaerobic fermentation (as in a silo). ]
Silanes D012821 [Compounds similar to hydrocarbons in which a tetravalent silicon atom replaces the carbon atom. They are very reactive, ignite in air, and form useful derivatives. ]
Sildenafil Citrate D000068677 [A PHOSPHODIESTERASE TYPE-5 INHIBITOR; VASODILATOR AGENT and UROLOGICAL AGENT that is used in the treatment of ERECTILE DYSFUNCTION and PRIMARY PULMONARY HYPERTENSION. ]
Silencer Elements, Transcriptional D037941 [Nucleic acid sequences that are involved in the negative regulation of GENETIC TRANSCRIPTION by chromatin silencing. ]
Silene D029751 [A plant genus of the family CARYOPHYLLACEAE. The common name of campion is also used with LYCHNIS. The common name of 'pink' can be confused with other plants. ]
Silent Information Regulator Proteins, Saccharomyces cerevisiae D038281 [A set of nuclear proteins in SACCHAROMYCES CEREVISIAE that are required for the transcriptional repression of the silent mating type loci. They mediate the formation of silenced CHROMATIN and repress both transcription and recombination at other loci as well. They are comprised of 4 non-homologous, interacting proteins, Sir1p, Sir2p, Sir3p, and Sir4p. Sir2p, an NAD-dependent HISTONE DEACETYLASE, is the founding member of the family of SIRTUINS. ]
