“Background: It is known that the prognostic value of cardiovascular risk factors differed between men and women, but data in the elderly are very limited.\n\nMethods: We assessed cardiovascular structural and functional measurements (intima-media thickness, pulse pressure, pulse wave velocity, left atrial dimension (LAD), arrhythmia, deceleration time of transmitral early diastolic flow and left ventricular ejection

fraction (LVEF)), by ultrasonography, blood pressure monitor, electrocardiography and applanation tonometry, as well as conventional cardiovascular risk factors (age, body mass index, smoke, total to high Src inhibitor density lipoprotein (HDL) cholesterol ratio, and plasma glucose), and investigated their associations with all-cause mortality in men and women, separately, in 331 consecutive patients (87 +/- 7 years, 74.0% female) with a history of cardiovascular disease from the geriatric departments. After a mean follow-up

of 378 days, 110 deaths were recorded.\n\nResults: In the full adjusted models, we found that increased LAD (hazard ratio [HR]=2.24 per 1-standard deviation [SD]; 95% confidential interval [CI]: 1.23-4.09), reduced LVEF (HR=0.60 per 1-SD; 95% CI: 0.380.96), and increased total-to-HDL cholesterol ratio (HR=1.99 per 1-SD; 95% CI: 1.05-3.78) were significant predictors of all-cause mortality in men, whereas the presence of arrhythmia (HR=2.47; 95% CI: 1.28-4.78), increased plasma glucose (HR=1.32 per 1-SD; 95% CI: 1.06-1.64) and decreased body mass index (HR=0.60 per 1-SD; 95% CI: 0.44-0.83) could significantly predict all-cause mortality in women.\n\nConclusions: Even in the last stage of lifespan, risk factors for all-cause death still differ significantly in men and women with

cardiovascular disease. (C) 2011 Elsevier Ireland Ltd. All rights reserved.”
“The alpha 7 nicotinic acetylcholine receptor is known to regulate a wide variety of developmental and secretory BI-D1870 research buy functions in neural and non-neural tissues. The mechanisms that regulate its transcription in these varied tissues are not well understood. Epigenetic processes may play a role in the tissue-specific regulation of mRNA expression from the alpha 7 nicotinic receptor subunit gene, CHRNA7. Promoter methylation was correlated with CHRNA7 mRNA expression in various tissue types and the role of DNA methylation in regulating transcription from the gene was tested by using DNA methyltransferase (DNMT1) inhibitors and methyl donors. CHRNA7 mRNA expression was silenced in SH-EP1 cells and bisulfite sequencing PCR revealed the CHRNA7 proximal promoter was hypermethylated. The proximal promoter was hypomethylated in the cell lines HeLa, SH-SY5Y, and SK-N-BE which express varying levels of CHRNA7 mRNA.
