Fibroblast growth factor-2 (FGF-2) is predominantly synthesized and secreted by astrocytes in adult brain. Our previous study showed that activation of classical dopamine receptor D(1) or D(2) elicits FGF-2 biosynthesis and secretion in astrocytes. Here, we report that astrocytic FGF-2 expression is also regulated by phosphatidylinositol (PI)-linked(More)

In this paper, a new method is proposed on face recognition by integrating data field and PCA(Principal Component Analysis). First, the state of the art is analyzed on PCA face recognition. Second, the method principle is presented. After the features are extracted from facial pictures with data field, faces are recognized by using PCA. Finally, a case is(More)
Apomorphine (APO) is an anti-parkinsonian drug currently in use, which provides relief of Parkinson's symptoms. However, the utility of APO is greatly hampered by its poor bioavailability and rapid metabolism. In the present study, O,O'-diacetyl-apomorphine, a prodrug of apomorphine, was synthesized and its biological activity was examined. The prodrug(More)
With the development of micro technology, the fuse for small-caliber projectiles tends to be miniaturized and intelligent, the traditional fuse no longer meets the requirements. In this paper, we demonstrate a micro safety and arming (S & A) device with small volume and high reliability in small caliber projectile platforms. The working principle of S & A(More)
A thermal-mechanical coupled finite element analysis model of solder joints is established, which plays a role in mechanical support and electrical connection in flip chip. Periodic temperature cycle load (−45°C∼125°C) applied on the solder joints and it will generate periodic internal stress and strain in the process of the(More)
