syndrom nemocných budov

A group of symptoms that are two- to three-fold more common in those who work in large, energy-efficient buildings, associated with an increased frequency of headaches, lethargy, and dry skin. Clinical manifestations include hypersensitivity pneumonitis (ALVEOLITIS, EXTRINSIC ALLERGIC); allergic rhinitis (RHINITIS, ALLERGIC, PERENNIAL); ASTHMA; infections, skin eruptions, and mucous membrane irritation syndromes. Current usage tends to be less restrictive with regard to the type of building and delineation of complaints. (From Segen, Dictionary of Modern Medicine, 1992)

syndrom chorého sinu

A condition caused by dysfunctions related to the SINOATRIAL NODE including impulse generation (CARDIAC SINUS ARREST) and impulse conduction (SINOATRIAL EXIT BLOCK). It is characterized by persistent BRADYCARDIA, chronic ATRIAL FIBRILLATION, and failure to resume sinus rhythm following CARDIOVERSION. This syndrome can be congenital or acquired, particularly after surgical correction for heart defects.

Signal Peptides

N-terminal, hydrophobic sequences which mediate the attachment of newly translated polypeptide chains to intracellular membranes; in some membrane proteins the signal peptide remains as a permanent anchor, while in secretory proteins it is cleaved.
CSP

The N-terminal sequence of a secreted protein that interacts with a signal recognition particle and is required for transport through the cell membrane.
NCI

Highly hydrophobic amino acid sequences of proteins that must cross through membranes to arrive at their functioning cellular location (such as secreted and membrane proteins). They are 15 to 60 amino acids long and reside at the amino-terminus (leader signal peptides) or internally. By binding to signal recognition particles, these sequences direct nascent protein-ribosome complexes to a membrane where the protein is inserted during translation. Signal peptides direct translational uptake of the protein by various membranes -endoplamic reticulum, mitochondrial, chloroplast, peroxisomal, etc. Leader signal sequences on non-membrane proteins are ultimately removed by specific peptidases.

signály – přenos

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.
MSH

any process which helps to produce biological responses to events in the environment or internal milieu; e.g., transduction of light into nerve impulses by the retina, or transduction of hormone binding into cellular events by hormone receptors.
CSP

The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal, e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light, and ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell, and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell. [GOC:go_curators, GOC:mtg_signaling_feb11]
GO

The process by which a cell responds to substances in its environment. The binding of a substance to a molecule on the surface of a cell causes signals to be passed from one molecule to another inside the cell. These signals can affect many functions of the cell, including cell division and cell death. Cells that have permanent changes in signal transduction molecules may develop into cancer.
NCI

A cellular process that involves a chemical or mechanical stimulus and results in a specific cellular response. This process is a central feature of a broad variety of physiologic responses.
