Chapter 3405 【3405】Dimensionality Reduction Strike

"Squad leader, say a few words." Ren Chongda cleared his throat, and as a gentleman's counselor, he took the initiative to relieve the girls in the class from their difficulties.

Yue Wentong looked at the person, and then said: "What he said is definitely not suitable for experimentation, he himself can't imagine what the specific infection is."

This is something everyone knows, so Li, who couldn't express his thoughts, squatted on the ground and drew circles.

"You think his idea is not good, what do you think?" Teacher Yuan asked.

"Teacher, it seems that there is no purpose in wanting to do a verification experiment before we can't guess the specific cause of the disease." Yue Wentong said frankly.

is that so?

Teacher Yuan made the ultimate character appear on the stage, and asked Xie Wanying: "This is the abnormality you discovered first, what do you think about it?"

"The evolution of myocardial fibrosis first involves the extracellular matrix, which includes collagen fibers, proteoglycans, glycoproteins and other substances. Among them, the extracellular matrix of the heart is mainly composed of type I and type III collagen fibers, and its role is mainly to support and protect the connection. Cardiomyocyte muscle bundles, etc. Under normal circumstances, the extracellular matrix is ​​in a static state. When stimulated by factors such as inflammation, ischemia, and high blood pressure, pathological changes occur in cardiomyocytes, which in turn triggers the defense function of the human immune system. The release of active factors such as cytokines from macrophages activates the transformation of quiescent extracellular matrix-producing cells into cardiac fibroblasts and ultimately into cardiac fibrosis."

After understanding this continuous pathological process, fibrosis detection can be carried out in a targeted manner, such as to detect various products and components produced during the above evolution process. The simplest example is to detect the content of collagen fibers when doing experiments.

What is the reason for saying this? This is because of the particularity of this pathological section, such as the direction of student Li's suspicion. Xie Wanying said: "It seems to be a hidden chronic evolution process, not an acute disease. If we do relevant experiments and speculate, we can detect hidden lesions in a way like detecting collagen fiber content at intervals."

After hearing this, the other students looked at the monitor.

Yue Wentong: Well, I knew it earlier.

Li's heart was immediately balanced: the monitor hit him, and then the monitor was hit by Xie's dimensionality reduction.

The teachers laughed on the spot. The gap between the students is really obvious, and some of them are really blank. This blank head does not refer to knowledge reserves. Regarding the pathological evolution process cited by student Xie, it is impossible for the other academic masters present not to know. When it was their turn to transform knowledge into ideas for designing experiments, the other students had no clue.

"As I said, she seems to have been engaged in scientific research and is quite familiar with this area." Teacher Yuan Fang said to Cao Yudong next to her.

"Yeah." Cao Yudong nodded his head twice, the smile in his eyes grew stronger, and he asked, "Do you want to do a similar experiment?"

The old man is very accurate in seeing people's minds. If you are not interested in academic issues in this area, you will not want to see such slices, you will not quickly pick out the faults of slices, and you will not say that you can quickly come up with relevant experimental design ideas.

Overall, Xie came prepared.

It has been a long time since the notice about the visit has been disclosed in advance, almost a few months, and Xie has made preparations, which shows that he attaches great importance to this visit and study.

In this regard, seniors like Cao Yudong feel very happy and happy. Therefore, Mr. Cao asked this question with another deep meaning: If you are interested in doing it, maybe I can help you.
