Sugarcane mosaic virus (SCMV) is one of devastating pathogens in maize (Zea mays L.), and causes serious yield loss in susceptible cultivars. An effective solution to control the virus is utilizing resistant genes to improve the resistance of susceptible materials, whereas the basic work is to analyze the genetic basis of resistance. In this study, maize(More)
p75NTR has been used to isolate esophageal and corneal epithelial stem cells. In the present study, we investigated the expression of p75NTR in esophageal squamous cell carcinoma (ESCC) and explored the biological properties of p75NTR+ cells. p75NTR expression in ESCC was assessed by immunohistochemistry. p75NTR+ and p75NTR- cells of 4 ESCC cell lines were(More)
OBJECTIVE Valve calcification involves transdifferentiation of valve interstitial cells (VICs) into osteoblasts. Twist-related protein 1 (TWIST1) has been established as a negative regulator of osteoblast differentiation in both mouse and human mesenchymal stem cells, but its function in human aortic VICs is unknown. In our study, we determined the(More)
OBJECTIVE To investigate the birth defect condition in Haidian district of Beijing city, 61,272 live-born infants who were delivered in Haidian Maternal and Child Health Hospital from 2003 to the March of 2009 are analyzed. METHODS Data was collected from the hospital's medical records and from the birth defect surveillance. RESULTS Among the newborns(More)
Hypoxia-inducible factor (HIF)-1α and-2α have diverse actions on the myocardium, but the importance of direct effects on cardiac myocytes is unclear. To define their regional accumulation and association with cardiomyocyte cell cycle change after myocardial infarction (MI), a rat MI model was established by occluding the coronary arteries. To further prove(More)
Accumulation of toxic amyloid-β (Aβ) in the cerebral cortex and hippocampus is a major pathological feature of Alzheimer's disease (AD). The neurotrophin receptor p75NTR has been proposed to mediate Aβ-induced neurotoxicity; however, its role in the development of AD remains to be clarified. The p75NTR/ExonIII-/- mice and APPSwe/PS1dE9 mice were crossed to(More)
Stable cell-matrix adhesion, re-endothelialization, and reconstitution represent important issues in creating autologous living heart valve, a close collaboration between growth factors and the extracellular matrix in these processes appears crucial. To prove this action, porcine decellularized valve constructs were precoated with fibronectin and seeded(More)
Several studies have shown that astrocytes release neurotransmitters into the extracellular space that may then activate receptors on nearby neurons. In the present study, the actions of adenosine 5'-O-(2-thiodiphosphate) (ADPbetaS)-activated astrocyte conditioned medium (ADPbetaS-ACM) on cultured dorsal spinal cord neurons were evaluated by using confocal(More)
P2 receptors have been implicated in the release of neurotransmitter and proinflammatory cytokines by the response to neuroexcitatory substances in astrocytes. In the present study, we examined the mechanisms of ADP and adenosine 5'-O-2-thiodiphosphate (ADPbetaS, ADP analogue) on glutamate release from cultured dorsal spinal cord astrocytes by using(More)
Neonatal hypoxia-ischemia (HI) produces neurodegeneration and brain injury, and leads to behavioral and cognitive dysfunction. Hyperbaric oxygen (HBO) treatment may potentially be neuroprotective in HI injury. The aim of this study was to examine any neuroprotection by HBO treatment on long-term neurological function in the rat model of neontatal HI.(More)
