OBJECTIVES To investigate the association between intake of fish and n-3 polyunsaturated fatty acids (n-3 PUFA) and the risk of breast cancer and to evaluate the potential dose-response relation. DESIGN Meta-analysis and systematic review of prospective cohort studies. DATA SOURCES PubMed and Embase up to December 2012 and references of retrieved(More)
The present work focused on the design of novel hydrogel microspheres based on both dextran- and gelatin-derived biomaterials, and discussed whether locally controlled delivery of IGF-I from dextran-co-gelatin hydrogel microspheres (DG-MP) was useful for periodontal regeneration enhancement. Microspheres were synthesized when gelatin was cooperating with(More)
High concentration of corticosterone (Cort) 0.2 mM was incubated with PC12 cells to simulate the lesion state of brain neurons in depressive illness, it was found that the inulin-type oligosaccharides extracted from Morinda officinalis, inulin-type hexasaccharide (IHS) at the doses of 0.625, 1.25 microM or desipramine (DIM) 0.25, 1 microM protected the PC12(More)
The objective of this study was to evaluate the biological activity enhancement of a novel glycidyl methacrylated dextran (Dex-GMA)/gelatin hybrid hydrogel containing microspheres loaded with bone morphogenetic proteins (BMP) as periodontal cell/tissue scaffold. Larger number of human periodontal ligament cells (PDLCs) attached was observed in scaffolds(More)
Initial investigation for new active herbal extract with inhibiting activity on JAK/STAT signaling pathway revealed that the extract of Caulis Trachelospermi, which was separated by 80% alcohol extraction and subsequent HP-20 macroporous resin column chromatography, was founded to strongly inhibit IFN-γ-induced STAT1-responsive luciferase activity(More)
Novel thermomechanical hydrogel scaffolds containing our previously prepared microspheres loaded with bone morphogenetic proteins (BMP) were successfully generated by radical crosslinking and low dose gamma-irradiation from combination of two kind of biomaterials: glycidyl methacrylated dextran (Dex-GMA) and gelatin. The structure of those resulting smart(More)
Since calcium phosphates (CaPs) were first proposed, a wide variety of formulations have been developed and continuously optimized, some of which (e.g. calcium phosphate cements, CPCs) have been successfully commercialized for clinical applications. These CaP-based biomaterials have been shown to be very attractive bone substitutes and efficient drug(More)
AIM To study the alkaloid constituents of the root of Lindera angustifolia Cheng. METHODS The constituents were isolated and purified by column chromatography and the structures were characterized by spectral analysis. RESULTS Seven aporphine alkaloids, laurotetanine (I), N-methyllaurotetanine (II), boldine (III), isoboldine (IV), norboldine (V),(More)
Stem cells have received a great deal of interest from the research community as potential therapeutic "tools" for a variety of chronic debilitating diseases that lack clinically effective therapies. Stem cells are also of interest for the regeneration of tooth-supporting tissues that have been lost to periodontal disease. Indeed, substantial data have(More)
