The effect of the newly synthesized compound 2-[4-[(2,5-difluorophenyl)methoxy]phenoxy]-5-ethoxyaniline (SEA0400) on the Na-Ca exchanger (NCX) was investigated and compared against that of 2-[2-[4-(4-nitrobenzyloxy)phenyl]ethyl]isothiourea (KB-R7943). In addition, the effects of SEA0400 on reperfusion injury in vitro and in vivo were examined. SEA0400 was(More)
The Na(+)/Ca(2+) exchanger (NCX) is involved in myocardial ischemia-reperfusion injuries. We examined the effects of 2-[4-[(2,5-difluorophenyl)methoxy]phenoxy]-5-ethoxyaniline (SEA0400), a potent and selective inhibitor of NCX, on myocardial ischemia-reperfusion injury models. In canine cardiac sarcolemmal vesicles and rat cardiomyocytes, SEA0400 potently(More)
TS-011, a potent and selective inhibitor of 20-HETE synthesis, has been described as providing significant benefits in animal stroke models. However, no studies have investigated changes in brain 20-HETE levels after cerebral ischemia. Also lacking are studies of TS-011 pharmacodynamics with respect to brain 20-HETE levels that may explain the benefits of(More)
The present study characterized the effects of TS-011 [N-(3-chloro-4-morpholin-4-yl) phenyl-N'-hydroxyimido formamide], a new selective inhibitor of the synthesis of 20-hydroxyeicosatetraenoic acid (20-HETE), on the metabolism of arachidonic acid by human and rat renal microsomes and the inhibitory effects of this compound on hepatic cytochrome P450 enzymes(More)
Crop leaves are subject to continually changing light levels in the field. Photosynthetic efficiency of a crop canopy and productivity will depend significantly on how quickly a leaf can acclimate to a change. One measure of speed of response is the rate of photosynthesis increase toward its steady state on transition from low to high light. This rate was(More)
In recent years, serum S100B has been used as a secondary endpoint in some clinical trials in which serum S100B has successfully indicated the benefits or harm done by tested agents. However, few reports describe serum S100B as an indicator of the efficiency of neuroprotective treatment in experimental stroke models, although serum S100B may be as useful(More)
We detected a QTL for single seed weight in soybean that was stable across multiple environments and genetic backgrounds with the use of two recombinant inbred line populations. Single seed weight (SSW) in soybean is a key determinant of both seed yield and the quality of soy food products, and it exhibits wide variation. SSW is under genetic control, but(More)
Previous studies have described microvascular disturbances downstream of occluded large vessels arising during the acute phase (several hours) following cerebral ischemic insult. Prolonged microvascular disturbances may cause delayed neuronal cell death in ischemic penumbral regions, leading to expanded brain infarctions and poor neurological and functional(More)
Activation of the Na+/Ca2+ exchanger may contribute to Ca2+ overload during reperfusion after transient ischemia. We examined the effects of 2-[4-[(2,5-difluorophenyl) methoxy]phenoxy]-5-ethoxyaniline (SEA0400), a selective inhibitor of Na+/Ca2+ exchange, on a canine model of ischemia/reperfusion injury (myocardial stunning). Myocardial stunning was induced(More)
BACKGROUND AND PURPOSE Arachidonic acid that is released following cerebral ischemia can be metabolized to 20-hydroxyeicosatetraenoic acid (20-HETE). 20-HETE is a potent vasoconstrictor that may contribute to ischemic injury. This study examined the effects of blockading the synthesis of 20-HETE with TS-011 on infarct size after transient occlusion of the(More)
