The group was formerly named the Defence of Literature and the Arts Society (DLAS).  It was founded in 1968 with the publisher John Calder as a prime mover behind it as a direct result of the "Last Exit to Brooklyn" novel publication trial.

Proletarskaya (Russian: Пролетарская ) is a Moscow Metro station in Yuzhnoportovy District, South-Eastern Administrative Okrug, Moscow.  It is on the Tagansko-Krasnopresnenskaya Line, between Taganskaya and Volgogradsky Prospekt stations.  Proletarskaya opened on 31 December 1966 as part of the Zhadovskiy radius.  The station is a typical of the 1960s column tri-span functional design and like many stations built at the time lacks the design and decorative innovations that some of the more famous Moscow Metro stations exhibit.  The architects Yuliya Kolesnikova and Yury Vdovin applied a bright theme.  The pillars (slightly widening at the top) are reveted with white marble, whilst the floor is covered with grey granite of various tones and with labradorite.  The walls are faced with glazed ceramic tiles of white and black (below platform level), which have decorations in the form of hammer and sickles made from anodized aluminium.  The station has underground vestibules interlinked with subways under the Krestyanskaya Zastava square with entrances covered by glazed concrete pavilions.  In 1997 a footbridge was built over the northbound line, which serves as a third exit to the common vestibule with the station Krestyanskaya Zastava of the Lyublinsko-Dmitrovskaya Line and also acts as a transfer point.  Currently the station has a passenger traffic of 61860 via surface and 120300 via the transfer. No Exit (French: "Huis Clos" , ] ) is a 1944 existentialist French play by Jean-Paul Sartre.  The original title is the French equivalent of the legal term "in camera", referring to a private discussion behind closed doors.  The play was first performed at the Théâtre du Vieux-Colombier in May 1944.  The play begins with three characters who find themselves waiting in a mysterious room.  It is a depiction of the afterlife in which three deceased characters are punished by being locked into a room together for eternity.  It is the source of Sartre's especially famous and often misinterpreted quotation "L'enfer, c'est les autres" or "Hell is other people", a reference to Sartre's ideas about the and the perpetual ontological struggle of being caused to see oneself as an object from the view of another consciousness. The external iliac arteries are two major arteries which bifurcate off the common iliac arteries anterior to the sacroiliac joint of the pelvis.  They proceed anterior and inferior along the medial border of the psoas major muscles.  They exit the pelvic girdle posterior and inferior to the inguinal ligament about one third laterally from the insertion point of the inguinal ligament on the pubic tubercle at which point they are referred to as the femoral arteries.  The external iliac artery is usually the artery used to attach the renal artery to the recipient of a kidney transplant. Mirage was a heavy metal band which was formed in 1983 from the ashes of two Welsh Rock/ Metal bands: 'Rough Justice' and 'Exit'.  The band were based in the valleys of South East Wales, UK.  Its members were Richard Morgan (aka "Wretch) on vocals, Richard Price on guitar, Carl Skinner on bass and Gerry Turner on drums.  In 1984, they released one track 'Blind Fury' on a compilation album produced by local record company 'Notepad Productions'.  This came to the attention of Malc Macmillan, author of the Encyclopaedia of New Wave of British Heavy Metal (NWoBHM) who described their track 'Blind Fury' as "truly one of the classic tracks of the entire NWoBHM genre" The rare Notepad Productions VOLUME I album remains highly sought after by collectors - featured in Record Collector Magazine in January 2015.  The band has enjoyed some recent attention from High Roller Records who have re-released the band's tracks Blind Fury/ Twilight Zone on black and white vinyl.  The cover features Richard Price's original 1979 Fender Stratocaster guitar alongside a Turner family artefact from World War II. Viroporins are small and usually hydrophobic multifunctional viralproteins that modify cellular membranes, thereby facilitating virus release from infected cells.  Viroporins are capable of assembling into oligomeric ion channels or pores in the host cell's membrane, rendering it more permeable and thus facilitating the exit of virions from the cell.  Many viroporins also have additional effects on cellular metabolism and homeostasis mediated by protein-protein interactions with host cell proteins.  Viroporins are not necessarily essential for viral replication, but do enhance growth rates.  They are found in a variety of viral genomes but are particularly common in RNA viruses.  Many viruses that cause human disease express viroporins, such as hepatitis C virus, HIV-1, influenza A virus, poliovirus, respiratory syncytial virus, and SARS-CoV.
