A genetic study of 32 local Chinese, three foreign pig breeds [Duroc (DU), Landrace and Yorkshire], and two types of wild boar (Hainan and Dongbei wild boar) based on 34 microsatellite loci was carried out to clarify the phylogeny of Chinese indigenous pig breeds. The allele frequencies, effective numbers of alleles, and the average heterozygosity within(More)
We present a computational method for operon prediction based on a comparative genomics approach. A group of consecutive genes is considered as a candidate operon if both their gene sequences and functions are conserved across several phylogenetically related genomes. In addition, various supporting data for operons are also collected through the(More)
Aneurysmal bone cyst (ABC) is an aggressive, pediatric bone tumor characterized by extensive destruction of the surrounding bone. Although first described over 60 years ago, its molecular etiology remains poorly understood. Recent work revealed that ABCs harbor translocation of TRE17/USP6, leading to its transcriptional upregulation. TRE17 encodes a(More)
Protein kinase C (PKC) activation in the heart has been linked to a hypertrophic phenotype and to processes that influence contractile function. To establish whether PKC activation is sufficient to induce an abnormal phenotype, PKCbeta was conditionally expressed in cardiomyocytes of transgenic mice. Transgene expression in adults caused mild and(More)
The consequences of endothelin receptor activation were examined in atrial tumor myocytes derived from transgenic mice (AT-1 cells). Endothelin-1 (endothelin) stimulates phosphoinositide hydrolysis in a dose-dependent manner. Endothelin also induces the rapid and transient translocation of protein kinase C (PKC)-epsilon immunoreactivity from the soluble to(More)
Previous studies established that thrombin stimulates phosphoinositide hydrolysis and modulates contractile function in neonatal rat ventricular myocytes. The present study further defines the signaling pathways activated by the thrombin receptor and their role in thrombin's actions in cardiac myocytes. The thrombin receptor-derived agonist peptide (TRAP, a(More)
BACKGROUND AND PURPOSE Alzheimer disease (AD) is a neurodegenerative disease characterized by progressive dementia. The hippocampus is particularly vulnerable to damage at the very earliest stages of AD. This article seeks to evaluate critical AD-associated regional changes in the hippocampus using machine learning methods. MATERIALS AND METHODS(More)
AIMS The objective of the present study was to verify the correlation of chromosomes 1p and 19q status and expressions of O(6)-methylguanine DNA methyltransferase (MGMT), p53 and Ki-67 in diffuse gliomas of World Health Organization grades II and III. METHODS A series of 146 diffuse gliomas, including 45 oligodendrogliomas, 42 oligoastrocytomas and 59(More)
The structure of R-phycoerythrin (R-PE) from Polysiphonia urceolata was determined at 2.8 A resolution. The crystals belong to space group R3 with unit cell dimensions of a = b = 189.8 A, c = 60.1 A. The subunit composition of R-PE is (alpha 2 beta 2)3 gamma. The three-dimensional structure of R-PE was solved by the multiple isomorphous replacement method.(More)
BACKGROUND Dentine hypersensitivity occurs easily on exposed dentine. This study aimed to evaluate the effectiveness of a novel bioactive glass-containing toothpaste on dentine permeability and remineralization. METHODS Thirty dentine discs were divided into three groups of 10 specimens each. The groups corresponded to the following brushing treatments:(More)
