Nanomaterials, as a new kind of materials, have been greatly applied in different fields due to their special properties. With the industrialization of nanostructured materials and increasing public exposure, the biosafety and potential influences on central nervous system (CNS) have received more attention. Nanosized zinc oxide (nanoZnO) was suggested to(More)
This work examines the relationship between 3-year pedestrian crash counts across Census tracts in Austin, Texas, and various land use, network, and demographic attributes, such as land use balance, residents' access to commercial land uses, sidewalk density, lane-mile densities (by roadway class), and population and employment densities (by type). The(More)
3-n-Butylphthalide (NBP) has been shown to have protective effects against ischemic stroke. In the present study, we investigated effects of l-3-n-butylphthalide (l-NBP) on the learning and memory impairment induced by chronic cerebral ischemia in rats. Male Wistar rats were administered 20 mg/kg l-NBP by gavage daily for 30 days after the bilateral common(More)
Members of the plant-specific IQ67-domain (IQD) protein family are involved in plant development and the basal defense response. Although systematic characterization of this family has been carried out in Arabidopsis, tomato (Solanum lycopersicum), Brachypodium distachyon and rice (Oryza sativa), systematic analysis and expression profiling of this gene(More)
Hydroxysafflor yellow A (HSYA) has angiogenesisregulating and neuro-protective effects, but its effects on vascular dementia (VaD) are unknown. In this study, 30 adult Sprague-Dawley rats were randomly allocated to five groups: normal, sham-operation, VaD alone (bilateral carotid artery occlusion), VaD plus saline (control), and VaD plus HSYA. One week(More)
Many studies have demonstrated the cytoprotective effects of hydrogen sulfide (H(2)S) in vitro and/or in vivo ischemic injury. The aim of the current study was to investigate whether exogenous H(2)S attenuates the neuronal injury induced by brain ischemia. As an H(2)S donor, sodium hydrosulfide (NaHS) was administered intraperitoneally (5.6 mg/kg/day,(More)
WRKY III genes have significant functions in regulating plant development and resistance. In plant, WRKY gene family has been studied in many species, however, there still lack a comprehensive analysis of WRKY III genes in the woody plant species poplar, three representative lineages of flowering plant species are incorporated in most analyses: Arabidopsis(More)
This paper develops an estimation strategy for and then applies a spatial autoregressive multinomial probit (SAR MNP) model to account for both spatial clustering and cross-alternative correlation. Estimation is achieved using Bayesian techniques with Gibbs and the generalized direct sampling (GDS). The model is applied to analyze land development decisions(More)
Self-organized gallium nitride nanodots have been fabricated using droplet heteroepitaxy on c-plane sapphire by plasma-assisted molecular beam epitaxy at different substrate temperatures and Ga fluxes. Nanoscale Ga droplets were initially formed on the sapphire substrate at high temperatures by Ga deposition from an effusion cell in an ultrahigh vacuum(More)
Hydroxysafflor yellow A (HSYA) is a drug that exerts angiogenesis regulatory and neuroprotective effects and has become an effective therapy for brain and heart ischemic disorders. There is no definite evidence supporting a therapeutic effect of HSYA in vascular dementia (VaD). We used HSYA in a rat model of chronic cerebral ischemia to determine its(More)
