Resveratrol is a natural phytoalexin with pharmacologic effects on several human diseases: carcinogenesis, coronary heart disease and neurodegenerative disease. Due to its poor water solubility, resveratrol must be bound to proteins to keep it at a high concentration in serum. In our work, the bindings of resveratrol to plasma proteins, human serum albumin(More)
OBJECTIVE Type 2 diabetes is an important risk factor for non-alcoholic fatty liver disease (NAFLD), but current guidelines provide conflicting recommendations on whether diabetic patients should be screened for NAFLD. We therefore studied the strategy of screening diabetic patients by FibroScan. DESIGN Liver fat and fibrosis were assessed by controlled(More)
Glycogen synthase kinase-3 (GSK-3) plays a critical role in neuronal apoptosis. The two mammalian isoforms of the kinase, GSK-3α and GSK-3β, are inhibited by phosphorylation at Ser-21 and Ser-9, respectively. Depolarization, which is vital for neuronal survival, causes both an increase in Ser-21/9 phosphorylation and an inhibition of GSK-3α/β. However, the(More)
IMPORTANCE In type 2 diabetes mellitus (T2DM), team management using protocols with regular feedback improves clinical outcomes, although suboptimal self-management and psychological distress remain significant challenges. OBJECTIVE To investigate if frequent contacts through a telephone-based peer support program (Peer Support, Empowerment, and Remote(More)
Algorithms are developed to convert data streams from multiple airborne and spaceborne remote sensors into layer-averaged cirrus bulk microphysical properties. Radiometers such as the Moderate-Resolution Imaging Spectroradiometer (MODIS) observe narrowband spectral radiances, and active remote sensors such as the lidar on the Cloud–Aerosol Lidar and(More)
Functional properties of protein disulfide isomerase A (PDIA) from Aspergillus niger were investigated using ribonuclease A, glyceraldehyde 3-phosphate dehydrogenase (GAPDH) and prochymosin as substrates. PDIA was shown to function as an isomerase catalyzing the refolding of denatured and reduced ribonuclease A. PDIA also exhibited trx-independent chaperone(More)
The molecular impact of diabetes mellitus on prostate gland has not been elucidated. In this study, we performed a whole-genome cDNA microarray analysis using a streptozotocin-induced diabetic rat model to identify the effects of diabetes on the gene expression profiles in prostate. Our study shows that diabetes causes changes in the expression of multiple(More)
China has a large burden of diabetes: in 2013, one in four people with diabetes worldwide were in China, where 11·6% of adults had diabetes and 50·1% had prediabetes. Many were undiagnosed, untreated, or uncontrolled. This epidemic is the result of rapid societal transition that has led to an obesogenic environment against a backdrop of traditional(More)
The progranulin (PGRN) is known to protect regulatory T cells (Tregs) from a negative regulation by TNF-α, and its levels are elevated in various kinds of autoimmune diseases. Whether PGRN directly regulates the conversion of CD4+CD25-T cells into Foxp3-expressing regulatory T cells (iTreg), and whether PGRN affects the immunosuppressive function of Tregs,(More)
We present an all-fiber-optic scanning multiphoton endomicroscope with 1.55 μm excitation without the need for prechirping femtosecond pulses before the endomicroscope. The system consists of a 1.55 μm femtosecond fiber laser, a customized double-clad fiber for light delivery and fluorescence collection, and a piezoelectric scan head. We demonstrate(More)
