做最强的自己，与子征战兮路漫长

Self-discipline, constantly seeking and actively engaging in the contests ("fighting" for opportunities, funding) is the only way to sharp your mind, to position yourself on the “bleeding-edge”, to let you confidently stand on your own feet in the flied you are in.

Proteoglycan
From Wikipedia, http://en.wikipedia.org/wiki/Proteoglycan
Jump to: navigation, search
Proteoglycans represent a special class of glycoproteins that are heavily glycosylated. They consist of a core protein with one or more covalently attached glycosaminoglycan chain(s). These glycosaminoglycan (GAG) chains are long, linear carbohydrate polymers that are negatively charged under physiological conditions, due to the occurrence of sulphate and uronic acid groups.

Hyaluronan
http://en.wikipedia.org/wiki/Hyaluronan
(also called hyaluronic acid or hyaluronate) is a non-sulfated glycosaminoglycan distributed widely throughout connective, epithelial, and neural tissues. It is one of the chief components of the extracellular matrix, contributes significantly to cell proliferation and migration, and may also be involved in the progression of some malignant tumors. The average 70 kg man has roughly 15 grams of hyaluronan in his body, one third of which is turned over (degraded and synthesised) every day.[1]

be good, be brave~~ hang on

well, buddy, I went to my advisor’s office this Monday to fix my course. The advisor is absent once more. A nice associate dean sent me some information. On Tuesday I have been there once more. But no body was in the office. Then on Wednesday, I fixed my core course finally. I want to take some psychological course as my selective course. But I was told I have to get the promise from the academic counselor in the other counselor department. But that academic counselor is absent for sick. Then this Thursday I run to that office more than 5 times to find that “not exist” person. Finally I found him on Friday at my 7th time trying. The only result I got is: “I have to get the promise by other Dean”. Under my expectation, that “other Dean” is “Not Available” now~~~ I try to find someone that can make an appointment. But the front-table-lady told me, we don’t make appointment here.

And my student ID card is still NA. The operator told me: “you are still not in the system”. But my advisor told me he had already login my information inside the system. I ask if there is a deadline for system “check in”. They told me it is 27th of this month. But my dorm will be stopped at 28th, which means, if I can not get my ID card, I can’t move in my new dorm… and there is no place for my formal one and I need my ID card for my chest x-ray in hospital on 28th.

All those above is acceptable. What I can’t bear is the lib close at 5pm on Friday and Sat. How could I finish my daily task then?
--------------------------------------------------------------------------------------
Good news is: I DO LIKE MY DAILY READING (ROBBIN’S PATH)!
It is really a enjoyment for me~~ SO INTERESTING!

Angiogenesis
http://en.wikipedia.org/wiki/Angiogenesis
it is a physiological process involving the growth of new blood vessels from pre-existing vessels. Though there has been some debate over this, vasculogenesis is the term used for spontaneous blood-vessel formation, and intussusception is the term for new blood vessel formation by splitting off existing ones.
Angiogenesis is a normal process in growth and development, as well as in wound healing. However, this is also a fundamental step in the transition of tumors from a dormant state to a malignant state.

Vasculogenesis
http://en.wikipedia.org/wiki/Vasculogenesis
it is the process of blood vessel formation occurring by a de novo production of endothelial cells.
Though similar to angiogenesis, the two are different in one aspect: the term angiogenesis denotes the formation of new blood vessels from pre-existing ones, while vasculogenesis is the term used for the formation of new blood vessels when there are no pre-existing ones. For example, if a monolayer of endothelial cells begin sprouting to form capillaries, angiogenesis is occurring. Vasculogenesis, in contrast, first believed to occur only during embryologic development, is the term for when endothelial precursor cells (angioblasts) migrate and differentiate in response to local cues (such as growth factors and extracellular matrix) to form new blood vessels. These vascular trees are then pruned and extended through angiogenesis. Recently, however, it was realized that vasculogenesis can also occur in the adult organism. Circulating endothelial progenitor cells (derivatives of stem cells) were identified and reportedly able to contribute, albeit to varying degrees, to neovascularization, such as during tumor growth, or to the revascularization process following trauma, e.g. after cardiac ischemia.

the meaning of "de novo" is "new" or "again"?
