There has been little agreement regarding the mechanism by which proline reduces heavy metal stress. The present work examines the relationship between Hg(2+)-induced oxidative stress and proline accumulation in rice and explores the possible mechanisms through which proline protects against Hg(2+) stress. The effect of proline on alleviation of Hg(2+)(More)
Previous studies indicate resveratrol pretreatment can protect cardiomyocytes. However, it is largely unknown whether resveratrol protects cardiomyocytes when applied at reperfusion. The purpose of this study was to investigate whether resveratrol given at reoxygenation could protect cardiomyocytes under the anoxia/reoxygenation (A/R) condition and to(More)
Pm21 is an effective gene for powdery mildew resistance transferred from Haynaldia villosa into common wheat cultivars. No virulence against this gene has been detected so far. A set of 42 powdery mildew isolates collected in Israel and tested in the current study also revealed no virulence against this gene. Pm21 was previously reported to be located on(More)
Powdery mildew, caused by Blumeria graminis f. sp. tritici (Bgt) is one of the most important wheat diseases worldwide. Wild emmer wheat, Triticum turgidum ssp. dicoccoides, the tetraploid ancestor (AABB) of domesticated bread and durum wheat, harbors many important alleles for resistance to various diseases, including powdery mildew. In the current study,(More)
PURPOSE To determine whether -CONH-(CH(2))(6)-NH(3)(+)Cl(-) functionalized single-walled carbon nanotubes (SWNT) carrying complexed small interfering RNA (siRNA) can enter into tumor cells, wherein they release the siRNA to silence the targeted gene. EXPERIMENTAL DESIGN -CONH-(CH(2))(6)-NH(3)(+)Cl(-) was used to mediate the conjugation of telomerase(More)
The true programmed mechanisms of delayed neuronal death induced by global cerebral ischemia/reperfusion injury remain incompletely characterized. Autophagic cell death and programmed necrosis are 2 kinds of programmed cell death distinct from apoptosis. Here, we studied the death mechanisms of hippocampal cornu ammonis 1 neuronal death after a 20-minute(More)
Water and nitrogen are two of the most critical inputs required to achieve the high yield potential of modern corn varieties. Under most agricultural settings however they are often scarce and costly. Fortunately, tremendous progress has been made in the past decades in terms of modeling to assist growers in the decision making process and many tools are(More)
OBJECTIVE Bone marrow mesenchymal stem cells (MSCs) have the potential to repair the infarcted myocardium and improve cardiac function. However, this approach is limited by its poor viability after transplantation, and controversy still exists over the mechanism by which MSCs contribute to the tissue repair. METHODS The human heme oxygenase-1 (hHO-1) was(More)
Heme oxygenase-1 (HO-1) is a stress-inducible enzyme with diverse cytoprotective effects, and reported to have an important role in angiogenesis recently. Here we investigated whether HO-1 transduced by mesenchymal stem cells (MSCs) can induce angiogenic effects in infarcted myocardium. HO-1 was transfected into cultured MSCs using an adenoviral vector. 1 ×(More)
The present study was to determine the effects of the heme oxygenase-1 (HO-1) modified mesenchymal stem cells (MSCs) transplantation into acute MI hearts on normalizing the ratio of MMPs/TIMPs and remodeling in infarcted myocardium. HO-1 was transfected into cultured MSCs using an adenoviral vector. 1 x 10(6) Ad-HO-1-transfected MSCs (HO-1-MSCs) or(More)
