A hybrid GA (genetic algorithm)-based clustering (HGACLUS) schema, combining merits of the Simulated Annealing, was described for finding an optimal or near-optimal set of medoids. This schema maximized the clustering success by achieving internal cluster cohesion and external cluster isolation. The performance of HGACLUS and other methods was compared by(More)
Geminin is a dual-function protein unique to multicellular animals with roles in modulating gene expression and preventing DNA re-replication. Here, we show that geminin is essential at the beginning of mammalian development to prevent DNA re-replication in pluripotent cells, exemplified by embryonic stem cells, as they undergo self-renewal and(More)
The mammalian cell cycle is regulated by the cyclin/cyclin-dependent kinase (CDK) phosphorylation of the retinoblastoma (pRB) family of proteins. Cyclin D1 with its CDK4/6 partners initiates the cell cycle and acts as the link between extracellular signals and the cell cycle machinery. Estradiol-17beta (E2) stimulates uterine epithelial cell proliferation,(More)
In mice, the uterus becomes transiently receptive to the hatched blastocyst on the day of implantation to allow its attachment to the luminal epithelium and subsequent invasion into the uterus. This uterine preparation for implantation is regulated by estradiol-17beta and progesterone, acting through their transcription factor receptors. Using(More)
The angiotensin-1-converting enzyme (ACE) gene has been suggested to be involved in the development of metabolic syndrome (MetS). However, results have been inconsistent. In this study, a meta-analysis was performed to investigate the association between ACE insertion/deletion (I/D) polymorphism and MetS. Published literature from PubMed, EMBASE, and ISI(More)
Pringle maneuver (Pm) is advocated for the reduction of blood loss during liver surgery, while postoperative infections continue to be a frequent complication after hepatic resection and liver transplantation. To investigate the effect of the Pringle maneuver on systemic bacterial translocation and endotoxemia in cirrhotic rats and cirrhotic rats with(More)
In the uterus, progesterone (P4) acts early in G1 as a physiological inhibitor of estradiol-17beta (E2)-induced epithelial cell proliferation. Gene expression profiling of uterine epithelial cell RNA isolated 3 h after hormonal treatment of ovariectomized mice revealed the co-coordinate down-regulation by P4 of >20 genes whose functions are associated with(More)
Many studies have suggested that transforming growth factor-β1 (TGF-β1) gene might be involved in the development of hypertension. However, results have been inconsistent. In this study, the authors performed a meta-analysis to investigate the associations of +869T/C and +915G/C polymorphisms in TGF-β1 gene with hypertension risk in Chinese. Published(More)
Tumor-propagating cells in acute leukemia maintain a stem/progenitor-like immature phenotype and proliferative capacity. Acute myeloid leukemia (AML) and acute T-lymphoblastic leukemia (T-ALL) originate from different lineages through distinct oncogenic events such as MLL fusions and Notch signaling, respectively. We found that Zfx, a transcription factor(More)
BACKGROUND Several distributions of country-specific blood pressure (BP) percentiles by sex, age, and height for children and adolescents have been established worldwide. However, there are no globally unified BP references for defining elevated BP in children and adolescents, which limits international comparisons of the prevalence of pediatric elevated(More)
