西班牙Certest滅活的福氏志賀氏菌抗原（天然提取物）

對從病人機體分離的肝臟及抗原抗體腫瘤組織進行分析，研究者發現，癌癥中ASPP2表達的欠缺和病人較低的生存率直接相關;蛋白ASPP2可以通過和E-鈣粘蛋白及β-連環蛋白的關聯來控制MET和EMT過程。zui后研究者Lu表示，近些年來我們已經對驅動EMT的過程研究地非常多了，但是對于MET過程的發生卻知之甚少，而MET過程對于機體的健康及癌癥的轉移又至關重要，而本文的zui大亮點就是我們鑒別出了MET的誘導子及守護者，這對于后期開發治療癌癥的新型靶向療法提供了新的研究思路和依據。
日本東京大學教授竹內昌治率領的研究小組24日宣布，通過把人工培養的肌肉組織安在人工關節上，他們成功制作出了能像人類手指那樣屈伸的人工手指。這一成果有望在再生醫療領域得到應用。
研究人員將大鼠的肌肉細胞植入特殊的凝膠層，然后將多個凝膠層放在一起進行培養，zui終培養出了長約8毫米、厚約1.5毫米的立體肌肉組織。
隨后，研究人員在長2厘米的塑料棒兩側分別安裝了人工培養出的大鼠肌肉組織，塑料棒正中安裝有關節。利用微弱的電流進行刺激后，肌肉就會收縮，而輪流刺激兩側的肌肉，就能使塑料棒像手指那樣屈伸。
以前利用肌肉活動人工關節時，肌肉會在約兩小時后收縮僵硬。而此次開發的人工關節由兩個肌肉組織牽拉，所以不容易變僵硬，兩天后仍能運動。這使得這種人工手指有望長期使用，從而能作為醫療用品進入實用階段。
如果進一步向肌肉組織加入血管和神經，就能制作出*可以替代人類手指的裝置。研究人員認為，這一成果有望用于肌肉抗原抗體癥等的治療。他們還準備利用這一成果開發形態樣貌更接近人體的機器人。
日本學者山中伸彌將oct4、Sox2、 Klf4、c-myc四個基因插入到成體細胞DNA中重編程細胞恢復到胚胎干細胞狀態，由此建立了iPS細胞。這些細胞可以向胚胎干細胞一樣，轉變為幾乎所有的組織類型。為此, 山中伸彌在2011年獲得諾貝爾獎。雖然iPS細胞有潛力發育為任何組織器官，但如何誘導它們往正確的方向分化問題尚未解決。
由中科院上海生命科學院/上海交大醫學院健康科學研究所金穎教授帶隊的關于“基于誘導多能干細胞技術的若干重大疾病模型與機理研究”的“973”科技部重大科學研究項目，就是希望能找到誘導iPS細胞的方法。

Analysis of the liver and antigen-antibody-tumor tissue isolated from the patient's body revealed that the lack of ASPP2 expression in cancer was directly linked to the lower survival rate of the patient; the protein ASPP2 was directly linked to E-cadherin and β-catenin To control the MET and EMT processes. Last researcher Lu said that in recent years we have studied very much about the EMT driving process but have little knowledge of the occurrence of MET events that are crucial for the health of the body and the transfer of cancer, The highlight of this article is that we identified the elicitors and guardians of MET, which provided a new research idea and basis for the later development of new targeted therapies for the treatment of cancer.
A team led by Professor Takeuchi Masaharu of the University of Tokyo in Japan announced on the 24th that they successfully produced artificial fingers that flexed like human fingers by putting artificial muscle tissue in artificial joints. This result is expected to be applied in the field of regenerative medicine.
Researchers planted muscle cells from rats into a special gel layer and then placed multiple gel layers together to create a three-dimensional muscle tissue approximay 8 mm long and 1.5 mm thick.
Subsequently, the researchers in the 2 cm long plastic rods installed on both sides of the artificial culture of rat muscle tissue, plastic rods installed in the middle section. When stimulated with a weak electric current, the muscles contract, and in turn, stimulate the muscles on either side, making the plastic rod bend like a finger.
Muscles used to contract muscle stiffness in about two hours after using artificial joints that previously used muscle activity. The artificial joint developed by the two muscle tissue stretch, it is not easy to become stiff, still can exercise two days later. This makes the artificial finger is expected long-term use, which can be used as a medical supplies into the practical stage.
If you further add blood vessels and nerves to muscle tissue, you can create a device that can compley replace human fingers. Researchers believe that this result is expected to be used for the treatment of muscle antigen antibody disease. They are also ready to use this achievement to develop robots that are closer to the human body in morphology.
Japanese scholars Shinya Yamanaka will oct4, Sox2, Klf4, c-myc four genes inserted into the adult cell DNA reprogrammed cells back to the embryonic stem cell state, thus establishing iPS cells. These cells, like embryonic stem cells, can be transformed into almost all tissue types. To this end, Yamanaka won the Nobel Prize in 2011. Although iPS cells have the potential to develop into any tissue and organ, the question of how to induce them in the right direction has not yet been resolved.
"973" major scientific research project of Ministry of Science and Technology led by Professor Jin Ying from Shanghai Institutes of Biological Sciences / Shanghai Jiaotong University School of Medicine and Institute of Health Sciences, Chinese Academy of Sciences on "Several models and mechanisms of induced diseases based on induced pluripotent stem cell technology" Find ways to induce iPS cells.
