Selective medial temporal volume reduction in the hippocampus of patients with idiopathic generalized tonic-clonic seizures.

Background: Different subtypes of idiopathic generalized epilepsy may indicate different mechanisms and outcomes, suggesting that it is necessary to use a 'pure sample' of a single subtype.

Methods: A volumetric study, in conjunction with cognition assessments, was performed in a pure sample of patients with idiopathic generalized tonic-clonic seizures (IGE-GTCS; 15 males and 15 females) matched with normal control subjects (15 males and 17 females). The volumetric measurements were focused on the hippocampus and its surrounding structures, including the amygdala, the parahippocampal gyrus, the entorhinal cortex and the perirhinal cortex.

ACAT inhibitory activity of exudates from Calocedrus macrolepis var. formosana.

Cholesterol acyltransferase (ACAT) is an enzyme controlling cholesterol esterification in cells. Large amounts of cholesterol esters accumulate in macrophages and smooth muscle cells of blood vessel walls resulting in the initial stages of atherosclerosis. Thus, atherosclerosis might be inhibited through inhibition of the activity of ACAT.

Hepatoprotective effect of lucidone against alcohol-induced oxidative stress in human hepatic HepG2 cells through the up-regulation of HO-1/Nrf-2 antioxidant genes.

Lucidone was previously reported to exhibit anti-inflammatory activity in vitro and in vivo. In the present study, we characterized the mechanisms underlying the hepatoprotective effect of lucidone against alcohol-induced oxidative stress in vitro. Human hepatoma (HepG2) cells were pretreated with lucidone (1-10μg/mL) and then hepatotoxicity was stimulated by the addition ethanol (100mM).

Anti-inflammatory activity of Flavokawain B from Alpinia pricei Hayata.

Alpinia pricei (Zingiberaceae) is a spicy herb indigenous to Taiwan. A potent anti-inflammatory compound, flavokawain B (FKB), was obtained from A. pricei.

[An analysis on the relationship between susceptibility to cirrhosis and polymorphisms at C-1350T and G-944C sites of CIITA gene promoter IV in chronic HBV carriers].

Objective: To investigate the relationship between the susceptibility to cirrhosis and the single nucleotide polymorphisms (SNPs) at C-1350T and G-944C loci of class II transactivator (CIITA) gene promoter IV in chronic HBV carriers.

Methods: C-1350T and G-944C loci of CIITA gene promoter IV were analyzed by sequence-specific primer PCR (PCR-SSP) in 544 chronic HBV carriers and 125 non-HBV infected healthy blood donors.

Results: Among the chronic viral hepatitis B patients, there were significantly decreased frequencies of CC and TG haplotypes, and significantly increased frequency of CG haplotype among patients with liver cirrhosis (CG vs.

Antiinflammatory activity of Lindera erythrocarpa fruits.

In this study, in vitro and in vivo antiinflammatory activities of fruits from Lindera erythrocarpa Makino were evaluated. The ethyl acetate soluble fraction derived from the ethanol extract of L. erythrocarpa fruits inhibited significantly nitric oxide (NO) production in lipopolysaccharide (LPS) induced NO in the murine macrophage cell line (RAW264.

[Construction of eukaryotic expression vectors containing different haplotype cDNA of human CIITA gene].

Objective: To construct eukaryotic expression vectors containing three different haplotype cDNAs of human CIITA gene.

Method: cDNA fragments of three different CIITA haplotypes were obtained by inducing one or two single nucleotide mutations of wild type recombinant plasmid EBS-NPL-CIITA cDNA, which correspond to two non-homonymy single nucleotide polymorphism (SNP) sites in the coding region of human CIITA gene, using overlap extension PCR site-directed mutagenesis technology. The above-mentioned three haplotype cDNAs were respectively cloned to EBS-NPL-CIITA linearized vectors.
