Gap junction: A gap junction may also be called a nexus or macula communicans. When found in nerves they are also referred to as an electrical synapse.History of communication studies: Various aspects of communication have been the subject of study since ancient times, and the approach eventually developed into the academic discipline known today as communication studies.Cellular microarray: A cellular microarray is a laboratory tool that allows for the multiplex interrogation of living cells on the surface of a solid support. The support, sometimes called a "chip", is spotted with varying materials, such as antibodies, proteins, or lipids, which can interact with the cells, leading to their capture on specific spots.Gene signature: A gene signature is a group of genes in a cell whose combined expression patternItadani H, Mizuarai S, Kotani H. Can systems biology understand pathway activation?Connexon: In biology, a connexon, also known as a connexin hemichannel or a pannexin channel, is an assembly of six proteins called connexins that form the pore for a gap junction between the cytoplasm of two adjacent cells. This channel allows for bidirectional flow of ions and signaling molecules.Midkine: Midkine (MK or MDK) also known as neurite growth-promoting factor 2 (NEGF2) is a protein that in humans is encoded by the MDK gene.Matrix model: == Mathematics and physics ==Drosophila embryogenesis: Drosophila embryogenesis, the process by which Drosophila (fruit fly) embryos form, is a favorite model system for geneticists and developmental biologists studying embryogenesis. The small size, short generation time, and large brood size make it ideal for genetic studies.Master of Advanced Studies in Interaction Design (MAIND), SUPSIGlossary of communication disorders: This is a glossary of medical terms related to communications disorders such as blindness and deafness.Key word signing: Key word signing is a technique of Simultaneous Communication whereby the communication partner of the user will use both natural speech and also produce signs for the words that carry the most important information.Windsor, J.Dyssemia: Dyssemia is a difficulty with receptive and/or expressive nonverbal communication. The word comes from the Greek roots dys (difficulty) and semia (signal).Foreign branding: Foreign branding is an advertising and marketing term describing the implied cachet or superiority of products and services with foreign or foreign-sounding names.Acknowledgement (data networks): In data networking, an acknowledgement (or acknowledgment) is a signal passed between communicating processes or computers to signify acknowledgement, or receipt of response, as part of a communications protocol. For instance, ACK packets are used in the Transmission Control Protocol (TCP) to acknowledge the receipt of SYN packets when establishing a connection, data packets while a connection is being used, and FIN packets when terminating a connection.DR Systems: DR Systems, Inc. is an independent provider of enterprise imaging and information management systems for hospitals, integrated healthcare networks and diagnostic imaging centers.
