80th human body organ identified.

C’est quoi l’interstitium, présenté comme “le 80e organe” du corps humain ? What is interstitium?

Des chercheurs américains affirment avoir identifié un nouvel organe, dont la connaissance pourrait permettre de mieux comprendre la propagation de certains cancers. Mais d’autres scientifiques se montrent sceptiques sur cette découverte. American researchers have claimed to have positively identified a new organ, which, they say will allow better understanding of the development of certain cancers.

A quoi il ressemble, cet interstitium ? What does it resemble, this interstitium?

Imaginez un très fin matelas souple, gorgé de liquide. L’interstitium, tel que décrit par les chercheurs, est composé de faisceaux de collagène, résistants et flexibles, dont les espaces forment des bulles remplies de fluide. Et cet interstitium se retrouverait presque partout dans le corps : dans les veines et les artères, les poumons, tout au long du système digestif, dans la vessie, sous la peau, entre les fibres des muscles. Jusqu’à cette étude, on pensait que ces organes étaient chacun simplement entourés de tissu conjonctif dense et solide, sans connaître le détail de ce réseau complexe dont le liquide est une partie intégrante.

Imagine a very fine and supple mattress, stuffed with liquid. Interstitium, as described by the researchers, is composed of bundles (faisceaux) of collagene, tough and flexible, filling spaces with balls filled with fluid. And this interstitium is found nearly all over the body: in veins, arteries, lungs, all along the the digestive system, in the bladder (vessie), under the skin, between the muscle fibres. Up to this study it was thought that these organs  were each simply surrounded by dense and solid conjunctive tissue, without understanding the detail of the complex network including the integrated part played by liquid.

About bill

Worked in the technical / engineering area as a Science Laboratory Technician and as an Aeronautics Engineer. The artistic side involves writing under the nom de plume of Billy Olsenn, his recently written play 'A Case of Wine' was staged by the players group Straight Make-Up at the 2012 Birr one act drama festival. It's next staging was in the one act circuit is in Cavan, at Maudebawn on Sat 10 Nov 2012. Then it was performed in the Bray, Co.Wicklow at the very popular one act festival in January 2013. Next play is FEAR. A dark tale about revenge on the cruel death of two pensioners by young thugs. Neighbours hatch a devious and dangerous plan to exact old-style revenge. Bill is a member of the Drama League of Ireland and his plays have been critically vetted and certified as original pieces of work by the DLI. Another literary project is that of commemoration of an aircraft crash on Djouce mountain in Wicklow in 1946. Bill wrote articles for the 50th, 60th and most recently the 70th anniversary, (12 Aug 2016) all were published in the Wicklow Times and ensured the survivors of the crash, all French Girl Guides, were not forgotten. Articles reproduced on this website. But mostly this site gives a more general European and specific French slant on popular and not so popular articles of French news, translated to English by the author. Each article is translated on a paragraph by paragraph basis so easy to read in either language and even possible to improve either language by comparison of the short English and French paragraphs. Amusez vous bien. The author is currently writing an easy to read technical aviation book centered around the Fokker 50. Another interest is that dealt with in another of Bill's websites www.realnamara.net, a Statue of the mother of God, Mary. It was erected in 1972 in Dublin, at the end of the Bull Wall near Clontarf, and my grandfather William Nelson, was the main instigator of that project. I give talks on the history of the statue and my grandfather's adventurous and dangerous life at sea. Technical assistance with each website is by J O'N.
