To investigate the variation of Zn and Cd accumulation and tolerance of Sedum alfredii (a newly reported Zn/Cd hyperaccumulator), field surveys and hydroponic experiments were conducted among three populations of this species: two originating from old Pb/Zn mines in Zhejiang (ZJ) and Hunan (HN) Provinces and one from a "clean" site in Guangdong (GD)(More)
An analytical formulation for computing kinematic sensitivity of the spatial four-bar mechanism is presented. The experimental code developed is used to compute an assembled configuration for the mechanism due to a design variation. The mechanism is modeled using graph theory where a body is defined as a node and a kinematic joint is defined as an edge. The(More)
OBJECTIVE Rheumatoid arthritis (RA) is a destructive autoimmune polyarthritis that has been associated with a group of human leucocyte antigen (HLA)-DRB1 alleles that share a common amino-acid sequence at residues 70-74 called the shared epitope (SE). Recently, anti-cyclic citrullinated peptide (CCP) antibodies have also been reported to be associated with(More)
In response to the lack of readily available multimedia rich medical knowledge sources to support medical education and patient care, we designed and implemented a web-based video publishing platform. In order to promote the development of high-quality, up-to-date educational content, we have devised a scalable structure that allows online submissions and(More)
Inflammation plays an important role in cerebral ischemia reperfusion, which can cause severe damage to the brain and may lead to cerebral hemorrhage transformation. p38-mitogen-activated protein kinase (p38mapk) has been implicated in the etiology of a number of diseases because it is a cause of inflammation, but comparatively little research has been(More)
Blockade of extracellular high mobility group box 1 (HMGB1) can significantly prolong murine cardiac allograft survival. Here, we determined the role of HMGB1 in xenotransplantation. Sprague-Dawley rat hearts were transplanted heterotopically into BALB/c mice. Xenografts without any treatment developed predominant acute vascular rejection within 6 days.(More)
