Multicellular glial calcium waves may locally regulate neural activity or brain energetics. Here, we report a diffusion-driven astrocytic signal in the normal, intact brain that spans many astrocytic processes in a confined volume without fully encompassing any one cell. By using 2-photon microscopy in rodent cerebellar cortex labeled with fluorescent… (More)
BACKGROUND Considerable clinical data on the treatment of type 2 diabetes with incretin-based therapies (glucagon-like peptide 1 receptor agonists [GLP-1RAs] and dipeptidyl-peptidase IV [DPP-4] inhibitors) are available. OBJECTIVE This meta-analysis was performed to support the understanding of the overall evidence by summarizing the findings from studies… (More)
AIMS Exenatide has been demonstrated to improve glycaemic control in patients with type 2 diabetes, with no effect on heart rate corrected QT (QTc ) at therapeutic concentrations. This randomized, placebo- and positive-controlled, crossover, thorough QT study evaluated the effects of therapeutic and supratherapeutic exenatide concentrations on QTc . … (More)
OBJECTIVE To evaluate the long-term clinical effect of treatment with metreleptin (an analogue of human leptin) on glycemic and lipid abnormalities and markers of hepatic steatosis in patients with inherited or acquired lipodystrophy. METHODS Fifty-five patients (36 with generalized lipodystrophy and 19 with partial lipodystrophy) with at least 1 of 3… (More)
Many environmental data sets have a continuous domain, in time and/or space, and complex features that may be poorly modeled with a stationary Gaussian process (GP). We adapt stochastic volatility modeling to this context, resulting in a stochastic heteroscedastic process (SHP), which is unconditionally stationary and non-Gaussian. Conditional on a latent… (More)
Multi-substituted pentacenes, such as 1,2,3,4,6,8,9,10,11,13-decasubstituted pentacenes (Type I), 1,2,3,4,6,13-hexasubstituted pentacenes (Type II), 1,2,3,4-tetrasubstituted pentacenes (Type III), and 2,3-disubstituted pentacenes (Type IV), 1,2,3,4,6,11-hexasubstituted naphthacenes (Type V), 1,2,3,4-tetrasubstituted naphthacenes (Type VI), and… (More)
We have injected human CD34+lin- cells derived from cord blood (CB) into the goat fetuses via in utero at 45-55 days gestation under guidance of B-scan ultrasonograph. Sixty out of 68 fetuses injected survived to full term. The long-term survival of the human cells in transplant goat has been tested by various experimental methods, including FACS analysis,… (More)
OBJECTIVE To establish a human/goat hematopoietic stem cell (HSC) xenogeneic transplant model and to probe the engraftment, expansion and differentiation of human HSC in vivo. METHODS Human HSCs were isolated from human umbilical cord blood and 1 x 10(5) human HSCs were in utero transplanted into 50 fetal goats at the 55 - 65 the gestation days. The… (More)
Acknowledgments I would like to express my appreciation to Dr. Jianzhong Wang, my graduate advisor and thesis advisor, for his great amount of time, effort and support on my thesis. I am deeply grateful for his help and guidance during my two−year academic life at Sam Houston State University.
[reaction: see text] A new and efficient palladium-catalyzed reaction of o-diiodoarenes with internal alkynes produces naphthalenes or anthracenes in good to excellent yields. This procedure provides a simple, catalytic, and straightforward ring-extension method for constructing substituted polycyclic aromatic compounds.
