  1. We hope that our study will provide us with more comprehensive knowledge of the mechanisms of immune regulation and the roles that dc and complement play in innate and acquired immunity, as well as to lay a foundation for further exploration of the roles dc play in antigen - specific immune responses and immune tolerance from a new perspective. part i expression of complement receptors and complement - associated molecules on dendritic cells derived from distinct - origin at different stages of development two subsets of dendritic cells were generated from precursor cells isolated by means of magnetic cell separation system

  3. A white crystalline substance, c27h45oh, found in animal tissues and various foods, that is normally synthesized by the liver and is important as a constituent of cell membranes and a precursor to steroid hormones

    一種白色結晶物質，化學式為c27h45oh ，在動物組織和各類食物中都能發現，通常由肝臟合成，是細胞質膜重要組成以及類固醇荷爾蒙形成的前身。
  4. The study on the function and mechanism of phrip1 is important for clarifying how the cell plate and cell wall form in plants. in this study, full length of phrip1 is amplified by pcr and ligated into pks plasmid, then the bait plasmid, peg202 - phrip1, is constructed. the inseret gene are sure to be translated into the right fusion protein through its sequence. in the yeast two - hybrid system, the bait plasmid ( peg202 - phrip1 ) and a reporter plasmid ( psh18 - 34 ) are introduced into the yeast ( egy48 ) by co - transformation. then cdna library ( which is in pjg4 - 5 ) is screened and two genes are obtained. the two insert gene fragments are sequenced. one of them is plastocyanin, the other is putative photosystem i reaction center subunit ii precursor, both of them are the necessary components of photosynthetic chain

    成膜素相關蛋白1 （ phrip1 ）是一個含608個氨基酸的蛋白質，它對于植物胞質分裂中細胞板的形成起到了十分重要的作用。研究phrip1的功能和機制，對在分子水平上闡明植物細胞板以及細胞壁形成的機理具有重大的生物學意義。在本實驗中，根據phrip1的序列設計引物對其進行pcr擴增，得到該基因后將其連接到了pks質粒上，並進一步構建成了誘餌質粒peg202 - phrip1 。
  5. The synthesis of poly ( - hydroxybutyrate - co - - hydroxyvalerate ) by the strain g - iiiy from different precusor was studied. it was found that the strain g - iiiy could accumulate phbv with sucrose as carbon source and propionic acid or valeric acid as precursor. in 2l self - controlled fermentor, the dry cell weight, phbv concentration and phbv content reached 35. 8g ? l - 1, 22. 6g ? l - 1 and 38. 4 % respectively in the case of fermentation for 42 hours and the propionic acid as precursor

    研究了添加不同前體物， g - y菌株生產聚-羥基丁酸和聚-羥基戊酸共聚物（ phbv ）的發酵條件，結果表明，此菌株能以丙酸或戊酸為前體，在蔗糖為碳源的條件下合成phbv共聚物；在2l發酵罐中，以丙酸為前體，發酵16小時開始流加丙酸，根據發酵液ph值變化控制丙酸流加量，發酵42小時，細胞干重、 phbv產量和含量分別達到35 . 8g / l ， 22 . 6g / l ， 63 . 13 。

    立足於麻薩諸塞州的高級細胞技術院說他們發明了一條直接的方法將血管前體細胞直接從幹細胞中分離並且計劃在人身上測試它們。
  8. Rather than injecting undifferentiated stem cells into damaged tissue, using precursor cells from a later stage of development - - ones already “ programmed ” to become retina or some other type of cell - - may be more successful, he says

    不是通過注射未分化的幹細胞進入損傷組織，使用來自發育後期的前體細胞（已經程序化成為視網膜或其他種類的細胞）可能更成功。
