The purpose of the research was to determine the effect of nano-hydroxyapatite concentrations on initial enamel lesions under dynamic pH-cycling conditions. Initial enamel lesions were prepared in bovine enamel with an acidic buffer. NaF (positive control), deionized water (negative control) and four different concentrations of nano-hydroxyapatite (1%, 5%,(More)
Keywords: Lithium Isotope fractionation Deep continental crust Granulite xenolith Metamorphic terrane Samples from Archean high-grade metamorphic terranes in China and granulite-facies xenoliths from Australia (Chudleigh and McBride suites) and China (Hannuoba suite) have been analyzed to assess the Li concentrations and isotopic compositions of the middle(More)
Foundering of mafic lower continental crust into underlying convecting mantle has been proposed as one means to explain the unusually evolved chemical composition of Earth's continental crust, yet direct evidence of this process has been scarce. Here we report that Late Jurassic high-magnesium andesites, dacites and adakites (siliceous lavas with high(More)
BACKGROUND Esophageal cancer (EC) remains a leading cause of cancer-related deaths in Linzhou (formerly Linxian) and Huixian of Henan province, northern China, which has been well recognized as the highest incidence area for EC. The lack of useful chemoprevention agents and early detection methods is the key factors for stable EC incidence in these areas.(More)
AIMS We investigated the effects of iptakalim, a new ATP-sensitive potassium channel (K(ATP)) opener providing endothelial protection, on the progression of cardiac hypertrophy to failure in a rat model of pressure overloading caused by abdominal aortic banding (AAB). Endothelial dysfunction is central to cardiac hypertrophy and failure induced by pressure(More)
The purpose of this research was to investigate the wear behavior of early carious enamel remineralized with gallic acid. Forty natural human premolar specimens with early caries lesions were prepared. A remineralization pH-cycling treatment agent of 4000 ppm gallic acid was used for 12 days to treat the early lesions. The changes in microhardness were(More)
The level of transforming growth factor beta1 (TGFbeta1) and transforming growth factor betaII receptor (TGFbetaRII) was determined immunohistochemically in normal tissues and tissues with different severities of lesions (basal cell hyperplasia, BCH; dysplasia, DYS; carcinoma in situ, CIS; and squamous cell carcinoma, SCC) from surgically resected human(More)
INTRODUCTION Takayasu arteritis is a relatively rare type of large-vessel arteritis that primarily affects the aorta and its major branches, the coronary arteries, and the pulmonary arteries. Depending on the different groups of blood vessels involved in the disease process, the clinical presentation of Takayasu arteritis varies. Here we report a case of a(More)
Three distinct groups of eclogites (low-Mg–Ti eclogites, high-Ti eclogites and Mg-rich eclogites) and ultramafic rocks from the depth interval of 100–680 m of the Chinese Continental Scientific Drill Hole were studied. The low Mg#s (=100 ⁎ molar Mg/(Mg + Fe)) (81–84%) and low Ni (1150–1220 ppm) and high Fe 2 O 3 total (13–15 wt.%) contents of ultramafic(More)
BACKGROUND Smoking is related with insulin resistance and type 2 diabetes mellitus. Retinol-binding protein-4 is a new adipocytokine associated with insulin resistance. We investigated the serum levels of a series of adipocytokines including retinol-binding protein-4 in smokers and non-smokers to explore the possible roles of adipocytokines on smoking(More)
