Interstitium

[une_PASSionnée]

heyyy dans ce texte je n'ai pas compris ces réeponses elles sont toutes vraies: ca correspond à quelle partie du texte svp ? 

 

 

(infer) What reason(s) did NOT motivate Dr. Theise & colleagues to study samples from cancer-free persons?

 

 

To take part in fundamental research.

 

 

They wanted to check the validity of their research in any part of the human body.

 

 

To be published.

 

 

They had students who volunteered to help with the research.

coucou!

comme la question c'est "what reasons did NOT" en gros ils te demandent de procéder par élimination :

si tu trouves une des propositions dans le texte listée comme motivation du Dr, it's a reason that did motivate him ... Le reste qui n'est pas mentionné du coup ça ne fait pas partie des motivations.

C'est assez piégeux comme question, mais c'est plus clair pour toi maintenant ou pas?

mais comme je peux savoir que ca ne le motive pas alors que c pas dans le texte ?

Coucou @azmca18 tu peux me donner le sujet dont tu parles pour que j’ai le texte qui correspond à ta question, mercii ;)

couycou le voici :

The human body is about 60 percent water. About two-thirds of that water is found inside cells, but the other third is outside cells and is known as "interstitial" fluid. Although researchers already knew that there is fluid between individual cells, the idea of a larger, connected interstitium — in which there are fluid-filled spaces within tissues — had been described only vaguely in the literature, Theise said. The new study, he said, expands the concept of the interstitium by showing these structured, fluid-filled spaces within tissues and is the first to define the interstitium as an organ in and of itself.

 The new work is based on the use of a relatively new technology called a "probe-based confocal laser endomicroscopy" or pCLE. This tool combines an endoscope with a laser and sensors that analyze reflected fluorescent patterns and gives researchers a microscopic view of living tissues.

 Back in 2015, two of the study authors — Dr. David Carr-Locke and Dr. PetrosBenias— were using this technology when they saw something unusual while examining a patient's bile duct for cancer spread. They spotted a series of interconnected cavities in the tissue layer that did not match any known anatomy. When a pathologist made slides out of this tissue, the cavities disappeared — a mystery that was later found to be a consequence of the slide-making process.

 In the new study, the researchers first used pCLE on cancer patients who were undergoing surgery to remove the pancreas and the bile duct. The imaging technique indeed showed the fluid-filled spaces in the connective tissue. When the tissue samples were removed from the body, they were quickly frozen, which allowed the fluid-filled spaces to stay open so the researchers could see them under a microscope.

 Later, the researchers saw these same fluid-filled spaces in other samples of connective tissue taken from other parts of the body, in people without cancer. "The more tissues I saw, the more I realized it is everywhere," Theise said.

 The researchers think that the fluid-filled spaces may act as shock absorbers to protect tissues during daily functions.

 Theise noted that there may be quite a bit of information already known about this fluid-filled space because researchers "did not know what they were looking at." Indeed, the researchers plan to conduct a review of the scientific literature "for all the things we know about this [body part] but did not know we knew it," Theise said.

il me semble que comme l’a dit @ironmanon, tu peux savoir que ça ne le motive pas parce que justement ce n’est pas dans le texte. En gros cette question te demande de séléctionner les réponses qui ne sont pas dans le texte comme le fait d’être publié ici par exemple! (si j’ai bien compris)

Oui c’est ça @azmca18 ;)
