6-Hydroxyflavone (6HF), a naturally occurring flavonoid, was previously reported to bind to type A gamma-aminobutyric acid (GABA(A)) receptors benzodiazepine (BZ) site with moderate binding affinity. In the present study, we showed that 6HF partially potentiated GABA-induced currents in native GABA(A) receptors expressed in cortical neurons via BZ site, as(More)
Baicalin, a naturally occurring flavonoid, was previously reported to induce anxiolytic-like effect devoid of sedation and myorelaxation in mice, acting through type A gamma-aminobutyric acid (GABA(A)) receptor benzodiazepine (BZ) site. The present study further expanded the behavioral pharmacology profile of baicalin and subtype selectivity was explored as(More)
Self-renewable human pluripotent stem cells (hPSCs) serve as a potential unlimited ex vivo source of human cardiomyocytes (CMs) for cell-based disease modeling and therapies. Although recent advances in directed differentiation protocols have enabled more efficient derivation of hPSC-derived CMs with an efficiency of ∼50%-80% CMs and a final yield of ∼1-20(More)
The generation of human ventricular cardiomyocytes from human embryonic stem cells and/or induced pluripotent stem cells could fulfill the demand for therapeutic applications and in vitro pharmacological research; however, the production of a homogeneous population of ventricular cardiomyocytes remains a major limitation. By combining small molecules and(More)
BACKGROUND The aim of this study was to compare the Physiological and Operative Severity Score for the enumeration of Mortality and Morbidity (POSSUM), Portsmouth POSSUM (P-POSSUM), and Colorectal POSSUM (Cr-POSSUM) for predicting surgical mortality in Chinese colorectal cancer patients and to create new scoring systems to achieve better prediction.

Flavones have been studied for their activities via benzodiazepine site on the type-A γ-aminobutyric acid (GABA(A)) receptors, for which knowledge on structure-efficacy relationships has been rather limited in comparison to that on structure-affinity relationships. The present study focused on flavone 6-substitution, implied in previous studies being(More)
BACKGROUND Human (h) embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) serve as a potential unlimited ex vivo source of cardiomyocytes (CMs). However, a well-accepted roadblock has been their immature phenotype. hESC/iPSC-derived ventricular (v) CMs and their engineered cardiac microtissues (hvCMTs) similarly displayed positive(More)
A number of genetic mutations is associated with cardiomyopathies. A mutation in the coding region of the phospholamban (PLN) gene (R14del) is identified in families with hereditary heart failure. Heterozygous patients exhibit left ventricular dilation and ventricular arrhythmias. Here we generate induced pluripotent stem cells (iPSCs) from a patient(More)
BACKGROUND Non-coding single nucleotide polymorphisms (SNPs) in GABRB2, the gene for beta(2)-subunit of gamma-aminobutyric acid type A (GABA(A)) receptor, have been associated with schizophrenia (SCZ) and quantitatively correlated to mRNA expression and alternative splicing. METHODS AND FINDINGS Expression of the Exon 10 region of GABRB2 from minigene(More)
Human (h) embryonic stem cells (ESC) represent an unlimited source of cardiomyocytes (CMs); however, these differentiated cells are immature. Thus far, gene profiling studies have been performed with non-purified or non-chamber specific CMs. Here we took a combinatorial approach of using systems biology to guide functional discoveries of novel biological(More)
