DJ mix

A DJ mix or DJ mixset is a sequence of musical tracks typically mixed together to appear as one continuous track. DJ mixes are usually performed using a DJ mixer and multiple sounds sources, such as turntables, CD players, digital audio players or computer sound cards, sometimes with the addition of samplers and effects units, although it's possible to create one using sound editing software.

DJ mixing is significantly different from live sound mixing. Remix services were offered beginning in the late 1970s in order to provide music which was more easily beatmixed by DJs for the dancefloor. One of the earliest DJs to refine their mixing skills was DJ Kool Herc.Francis Grasso was the first DJ to use headphones and a basic form of mixing at the New York nightclub Sanctuary. Upon its release in 2000, Paul Oakenfold's Perfecto Presents: Another World became the biggest selling dj mix album in the US.

Music

A DJ mix is often put together with music from genres that fit into the more general term electronic dance music. Other genres mixed by DJ includes hip hop, breakbeat and disco. Four on the floor disco beats can be used to create seamless mixes so as to keep dancers locked to the dancefloor. Two of main characteristics of music used in dj mixes is a dominant bassline and repetitive beats. Music mixed by djs usually has a tempo which ranges from 120 bpm up to 160 bpm.

Audio mixing

Audio mixing is the process by which multiple sounds are combined into one or more channels. In the process, the source signals' level, frequency content, dynamics, and panoramic position are manipulated and effects such as reverb may be added. This practical, aesthetic, or otherwise creative treatment is done in order to produce a mix that is more appealing to listeners.

Audio mixing is practiced for music, film, television and live sound. The process is generally carried out by a mixing engineer operating a mixing console or digital audio workstation.

Recorded music

Before the introduction of multitrack recording, all the sounds and effects that were to be part of a recording were mixed together at one time during a live performance. If the mix wasn't satisfactory, or if one musician made a mistake, the selection had to be performed over until the desired balance and performance was obtained. However, with the introduction of multitrack recording, the production phase of a modern recording has radically changed into one that generally involves three stages: recording, overdubbing, and mixdown.

NK2 homeobox 1

NK2 homeobox 1 (NKX2-1), also known as thyroid transcription factor 1 (TTF-1), is a protein which in humans is encoded by the NKX2-1 gene.

Function

Thyroid transcription factor-1 (TTF-1) is a protein that regulates transcription of genes specific for the thyroid, lung, and diencephalon. It is also known as thyroid specific enhancer binding protein. It is used in anatomic pathology as a marker to determine if a tumor arises from the lung or thyroid. NKX2.1 can be induced by activin A via SMAD2 signaling in a human embryonic stem cell differentiation model.

Clinical significance

TTF-1 positive cells are found in the lung as type II pneumocytes and club cells. In the thyroid, follicular and parafollicular cells are also positive for TTF-1.

For lung cancers, adenocarcinomas are usually positive, while squamous cell carcinomas and large cell carcinomas are rarely positive. Small cell carcinomas (of any primary site) are usually positive. TTF1 is more than merely a clinical marker of lung adenocarcinoma. It plays an active role in sustaining lung cancer cells in view of the experimental observation that it is mutated in lung cancer.
