With the development of nanotechnology and its application in biomedicine, studies on the interaction between nanoparticles and cells have become increasingly important. To understand the surface and size effects on cell interaction of nanoparticles, the cellular uptake behaviors of two series of gold nanoparticles (AuNPs) with both positively and(More)
Diabetic peripheral neuropathy (DPN) is one of the most common complications of diabetes, but currently no protein biomarkers have been introduced into clinical diagnosis, especially among early-stage diabetic patients. Our previous study in animal model showed Toll-like receptor (TLR) 4 and its downstream signaling molecules were associated with DPN. To(More)
BACKGROUND Vitamin D deficiency and vitamin D receptor gene polymorphisms are known to be significantly associated with high myopia. Whether this genetic variant may impact primary open-angle glaucoma is largely unknown. This study investigated whether vitamin D receptor gene polymorphisms are altered in primary open-angle glaucoma subjects carrying the(More)
The role of the adventitia in vascular function and vascular lesion formation has been largely ignored. This article introduces the hypothesis that the activation of the adventitia, specifically the fibroblasts, contributes to the formation of intimal atherosclerotic lesions. The evidence for this hypothesis includes: (a) the early proliferative changes(More)
Chitosan as an antibacterial agent and heparin as an anti-adhesive agent were alternatively deposited onto aminolyzed poly(ethylene terephthalate) (PET) films to construct anti-adhesive and antibacterial multilayer films. The contact-angle and UV data verified the progressive buildup of the multilayer film by alternate deposition of the polyelectrolytes.(More)
Signaling via the T cell antigen receptor (TCR) during the CD4(+)CD8(+) double-positive developmental stage determines thymocyte selection and lineage commitment. Here we describe a previously uncharacterized T cell-expressed protein, Tespa1, with critical functions during the positive selection of thymocytes. Tespa1(-/-) mice had fewer mature thymic CD4(+)(More)
Antibacterial multilayer films containing nanosilver were prepared via layer-by-layer fashion. PET film was aminolyzed with 1,6-hexanediamine to introduce amino groups on PET film surface; chitosan-silver nitrate complex and heparin were alternately deposited onto an aminolyzed PET film surface, and subsequently, the silver ions within the multilayer films(More)
OBJECTIVE To our knowledge, no data have yet shown the combined effects of GSTM1/GSTT1 gene polymorphisms with high consumption of a fruit and vegetable diet on the body's antioxidant capacity. A 2-wk dietary intervention in healthy participants was conducted to test the hypothesis that the antioxidant biomarkers in individuals with different(More)
Inflammatory bowel diseases (IBDs) are complex multifactorial immunological disorders characterized by dysregulated immune reactivity in the intestine. Here, we investigated the contribution of Qa-1-restricted CD8(+) Treg cells in regulating experimental IBD in mice. We found that CD8(+) T cells induced by T-cell vaccination ameliorated the pathological(More)
Novel amphiphilic diblock copolymers, cholesterol-end-capped poly(2-methacryloyloxyethyl phosphorylcholine) (CMPC), which have poly(2-methacryloyloxyethyl phosphorylcholine) (poly(MPC)) as hydrophilic segment and cholesterol as hydrophobic segment, was specially designed as drug delivery systems. Fluorescence probe technique and transmission electron(More)
