- Anterior segment mesenchymal dysgenesis
Infobox disease Name Anterior segment mesenchymal dysgenesis Image Alt Caption DiseasesDB ICD10 ICD9 ICDO OMIM 107250 MedlinePlus eMedicineSubj eMedicineTopic MeshID Anterior segment dysgenesis ASD is a failure of the normal development of the tissues of the anterior segment of the eye. It leads to anomalies in the structure of the mature anterior segment, associated with an increased risk of glaucoma and corneal opacity. Peter s or Peters anomaly is a specific type of mesenchymal anterior segment dysgenesis, in which there is central corneal leukoma , adhesions of the iris anatomy iris and cornea , and abnormalities of the posterior corneal stroma, Descemet s membrane , corneal endothelium, Lens anatomy lens , and anterior chamber . ref cite pmid 9778695 ref Pathophysiology Several different gene mutations have been identified underlying these anomalies with the majority of ASD genes encoding Regulation of gene expression transcriptional regulators . In this review, the role of the ASD genes, PITX2 and FOXC1, is considered in relation to the embryology of the anterior segment, the biochemical function of these proteins, and their role in development and disease aetiology. The emerging view is that these genes act in concert to specify a population of mesenchymal progenitor cells, mainly of neural crest origin, as they migrate anteriorly around the embryonic optic cup . These same genes then regulate Mesenchymal stem cell mesenchymal cell differentiation to give rise to distinct anterior segment tissues. Development appears critically sensitive to gene dosage , and variation in the normal level of transcription factor activity causes a range of anterior segment anomalies. Interplay between PITX2 and FOXC1 in the development of different anterior segment tissues may partly explain the phenotypic variability and the genetic heterogeneity characteristic of ASD.

- Float chamber
Unreferenced date December 2009 A float chamber is a device for automatically regulating the supply of a liquid to a system. It is most typically found in the carburettor of a normally aspirated internal combustion engine , where it automatically meters the fuel supply to the engine. However, this arrangement is found in many automatic liquid systems, for example the cistern of a toilet could be said to be a type of float chamber. A float chamber works by allowing liquid within the chamber to lift a float which is linked to a valve which regulates the liquid intake. When the level is low, the float drops and opens the valve, allowing in liquid until the float rises sufficiently to close off the valve again. This is identical in principle to the ballcock valve. One drawback of the basic type of float chamber described is that it only operates correctly when it is the right way up, so more sophisticated solutions are needed in aircraft .

Important state ceremonies, including the State Opening of Parliament, were held in the Painted Chamber. The House of Lords usually met in the White Chamber. The British House of Commons House of Commons , however, did not have a chamber of its own it sometimes held its debates in the Chapter House of Westminster Abbey until a permanent home in the former St. Stephen s chapel became available in the 16th Century. At the High Court of Justice for the trial of Charles I trial of Charles I of England Charles I , the evidence of the witnesses summoned was heard in the Painted Chamber rather than Westminster Hall.

- Chamber theatre
Unreferenced date December 2006 Chamber theatre is a method of adapting literary works to the stage using a maximal amount of the work s original text and often minimal and suggestive settings. In Chamber Theater, narration is included in the performed text and the narrator might be played by multiple actors . Professor Robert S. Breen 1909 1991 introduced Chamber Theater to his Oral Interpretation Classes at Northwestern University in 1947. Northwestern s Professor of Performance Studies Frank Galati , who studied Chamber Theater with Dr. Breen, has directed highly acclaimed Chamber Theater Productions for the Goodman Theater and Steppenwolf Theatre Company Steppenwolf Theater Companies in Chicago. Galati s Chamber Theater adaptation of John Steinbeck s The Grapes of Wrath won two Tony Awards on Broadway. One of the most famous and elaborate examples of chamber theatre is David Edgar playwright David Edgar s The Life and Adventures of Nicholas Nickleby play The Life and Adventures of Nicholas Nickleby , in which Charles Dickens s characters narrate themselves in Grammatical person third person . Set pieces are carried in and taken away during the performance, rather than between scenes, and objects may be represented in a mimetic manner. Another example is Matthew Spangler s stage adaptation of Khaled Hosseini s novel The Kite Runner . blockquote DEFAULTSORT Chamber Theatre Category Theatrical genres Theatre stub uk ... more details
