Netrin Receptor DCC
Netrin receptor DCC, also known as DCC, or colorectal cancer suppressor is a protein which in humans is encoded by the ''DCC'' gene. DCC has long been implicated in colorectal cancer and its previous name was ''Deleted in colorectal carcinoma''. Netrin receptor DCC is a single transmembrane receptor. Since it was first discovered in a colorectal cancer study in 1990, ''DCC'' has been the focus of a significant amount of research. ''DCC'' held a controversial place as a tumour suppressor gene for many years, and is well known as an axon guidance receptor that responds to netrin-1. More recently DCC has been characterized as a #DCC as a dependence receptor, dependence receptor, and many hypotheses have been put forward that have revived interest in ''DCCs candidacy as a tumour suppressor gene, as it may be a ligand-dependent suppressor that is frequently epigenetically silenced. Background Early studies of colorectal tumours found that allelic deletions of segments of chromosome ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct Client-to-Client
Direct Client-to-Client (DCC) (originally Direct Client Connection) is an IRC-related sub-protocol enabling peers to interconnect using an IRC server for handshaking in order to exchange files or perform non-relayed chats. Once established, a typical DCC session runs independently from the IRC server. Originally designed to be used with ircII it is now supported by many IRC clients. Some peer-to-peer clients on napster-protocol servers also have DCC send/get capability, including TekNap, SunshineUN and Lopster. A variation of the DCC protocol called SDCC (Secure Direct Client-to-Client), also known as DCC SCHAT supports encrypted connections. An RFC specification on the use of DCC does not exist. DCC connections can be initiated in two different ways: * The most common way is to use CTCP to initiate a DCC session. The CTCP is sent from one user, over the IRC network, to another user. * Another way to initiate a DCC session is for the client to connect directly to the DCC ser ...

Digital Compact Cassette
Digital Compact Cassette (DCC) is a magnetic tape sound recording format introduced by Philips and Matsushita Electric in late 1992 and marketed as the successor to the standard analog Compact Cassette. It was also a direct competitor to Sony's MiniDisc (MD), but neither format toppled the then-ubiquitous analog cassette despite their technical superiority, and DCC was discontinued in October 1996. Another competing format, the Digital Audio Tape (DAT), had by 1992 also failed to sell in large quantities to consumers, although it was popular as a professional digital audio storage format. The DCC form factor is similar to the analog compact cassette (CC), and DCC recorders and players can play back either type: analog as well as DCC. This backward compatibility was intended to allow users to adopt digital recording without rendering their existing tape collections obsolete, but because DCC recorders couldn't record (only play back) analog cassettes, it effectively forced con ...

Digital Command Control
Digital Command Control (DCC) is a standard for a system for the digital operation of model railways that permits locomotives on the same electrical section of track to be independently controlled. The DCC protocol is defined by the Digital Command Control Working group of the US National Model Railroad Association (NMRA), which owns the trademark for the DCC logo. History A digital command control system was developed (under contract by Lenz Elektronik GmbH of Germany) in the 1980s for two German model railway manufacturers, Märklin and Arnold. The first digital decoders that Lenz produced appeared on the market early 1989 for Arnold ( N scale) and mid 1990 for Märklin ( Z scale, H0 scale and 1 gauge; Digital=). Märklin and Arnold exited the agreement over patent issues, but Lenz continued to develop the system. In 1992 Stan Ames, who later chaired the NMRA/DCC Working Group, investigated the Märklin/Lenz system as possible candidate for the NMRA/DCC standards. When the N ...

N,N'-Dicyclohexylcarbodiimide
is an organic compound with the chemical formula (C6H11N)2C. It is a waxy white solid with a sweet odor. Its primary use is to couple amino acids during artificial peptide synthesis. The low melting point of this material allows it to be melted for easy handling. It is highly soluble in dichloromethane, tetrahydrofuran, acetonitrile and dimethylformamide, but insoluble in water. Structure and spectroscopy The C−N=C=N−C core of carbodiimides (N=C=N) is linear, being related to the structure of allene. The molecule has idealized C2 symmetry. The N=C=N moiety gives characteristic IR spectroscopic signature at 2117 cm−1. The 15N NMR spectrum shows a characteristic shift of 275 ppm upfield of nitric acid and the 13C NMR spectrum features a peak at about 139 ppm downfield from TMS. Preparation DCC is produced by the decarboxylation of cyclohexylisocyanate using phosphine oxides as a catalyst: :2 C6H11NCO → (C6H11N)2C + CO2 Alternative catalysts for th ...

Dynamic Combinatorial Chemistry
Dynamic combinatorial chemistry (DCC); also known as constitutional dynamic chemistry (CDC) is a method for the generation of new molecules formed by reversible reaction of simple building blocks under thermodynamic control.Schaufelberger, F.; Timmer, B.

Distributed Checksum Clearinghouse
Distributed Checksum Clearinghouse (also referred to as DCC) is a method of spam email detection. The basic logic in DCC is that most spam mails are sent to many recipients. The same message body appearing many times is therefore bulk email. DCC identifies bulk email by calculating a fuzzy checksum on it and sending that to a DCC server. The server responds with the number of times it has received that checksum. An individual email will create a score of 1 each time it is processed. Bulk mail can be identified because the response number is high. The content is not examined. DCC works over the UDP protocol and uses little bandwidth. DCC is resistant to hashbusters A hash buster is a program which randomly adds characters to data in order to change the data's hash sum. This is typically used to add words to spam e-mails, to bypass hash filters. As the e-mail's hash sum is different from the sum of e-mail ... because "the main DCC checksums are fuzzy and ignore aspects of m ...

Dosage Compensation Complex
Dosage compensation is the process by which organisms equalize the expression of genes between members of different biological sexes. Across species, different sexes are often characterized by different types and numbers of sex chromosomes. In order to neutralize the large difference in gene dosage produced by differing numbers of sex chromosomes among the sexes, various evolutionary branches have acquired various methods to equalize gene expression among the sexes. Because sex chromosomes contain different numbers of genes, different species of organisms have developed different mechanisms to cope with this inequality. Replicating the actual ''gene'' is impossible; thus organisms instead equalize the ''expression'' from each gene. For example, in humans, female (XX) cells randomly silence the transcription of one X chromosome, and transcribe all information from the other, expressed X chromosome. Thus, human females have the same number of expressed X-linked genes per cell as do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dhaka City Corporation
Dhaka City Corporation (DCC) was the former self-governing corporation that was entrusted with the task of administering the municipal affairs of Dhaka. The incorporated area was divided into several wards. Each ward has an elected ward commissioner. The mayor of the city was elected by popular vote every five years, although the last mayoral election took place in 2002. The corporation was dissolved by the Local Government (City Corporation) Amendment Bill 2011 on 29 November, passed in the Parliament of Bangladesh, and formally ceased to exist on 1 December 2011, following the President's approval, making way for a Dhaka North and a Dhaka South city corporations. History Dacca Municipality, the predecessor of the city corporation, was established on 1 August 1864. The first elected chairman was Ananda Chandra Roy. Prior to that, a ''Committee for the improvement of Dacca'' was formed in 1823. The Act of 1884 added the provision of elected representatives called commissione ...
