Primitive stromal cells can be isolated from umbilical cord Wharton's jelly (UC-PSCs). Umbilical cord can be easily obtained without causing pain to donors, and the procedure avoids ethical and technical issues. UC-PSCs are more primitive than mesenchymal stem cells (MSCs) isolated from some other tissue sources. In this study, UC-PSCs were induced to(More)
As a new member of the polyhydroxyalkanoate (PHA) family, poly(3-hydroxybutyrate-co-3-hydroxyvalerate-co-3-hydroxyhexanoate) (PHBVHHx) was produced by recombinant Aeromonas hydrophila 4AK4. PHBVHHx showed a rougher surface and had higher hydrophobicity than the well-studied polymers poly(L-lactic acid) (PLA) and poly(3-hydroxybutyrate-co-3-hydroxyhexanoate)(More)
Ca2+ signaling regulation plays an important role in triggering and/or maintaining atrial fibrillation (AF). Little is known about the relationship of the inositol-1,4,5-triphosphate receptors (InsP3Rs) and ryanodine receptors (RyRs) in left atrium to chronic AF. In this study, we investigated the expression and function of InsP3R1, InsP3R2 and RyR2 in a(More)
5-Hydroxtryptamine (5-HT, serotonin) has been recognized not only as a neurotransmitter and vasoactive agent, but also as a growth factor. 5-HT mainly binds to 5-HT2 receptors or 5-HT1 receptors on cell surfaces to stimulate cell proliferation through Ras or MAPK (mitogen-activated protein kinase) pathways in many cell types. It has been reported that 5-HT(More)
OBJECTIVE To observe therapeutic effect of acupuncture for regulating the liver on depressive neurosis. METHODS In a multi-center randomized controlled trial, 440 patients were divided into 3 groups: Acupuncture group for regulating the liver (Acup., 176 cases) was treated by acupuncture at Siguan Points, i.e., bilateral Hegu (LI 4) and Taichong (LR 3),(More)
5-hydroxtryptamine (5-HT, serotonin) has been recognized not only as a neurotransmitter and vasoactive agent, but also as a growth factor. 5-HT mainly binds to 5-HT(2) receptors or 5-HT(1) receptors on cell surface to stimulate cell proliferation through Ras or MAPK pathway in many cell types. It has been reported that 5-HT stimulates megakaryocytopoiesis(More)
OBJECTIVE To investigate the expression and function changes of inositol 1,4,5-triphosphate receptor (IP3R) and ryanodine receptor (RyR) in the atrial myocytes during atrial fibrillation. METHODS Ten adult mongrel dogs were randomly divided into 2 groups: 5 dogs underwent continuous rapid atrial pacing (500 beats/min) for twenty-four weeks to create(More)
