| 1 | Iatrogenic atrial septal defects after transseptal puncture for percutaneous left atrial appendage occlusion and their hemodynamic effects显示文摘Background Percutaneous left atrial appendage occlusion(LAAO)requires puncture of the interatrial septum.The immediate hemodynamic effects of iatrogenic atrial septal defects(iASD)after LAAO have not been examined so far.We aimed at evaluat-ing these effects through invasive measurements of pressure and oxygen saturation.Moreover,we assessed the incidence of per-sistent iASD at three months.METHODS Forty-eight patients scheduled for percutaneous LAAO were prospectively included in the study.Pressure and oxygen saturation were measured(1)in the right atrium(RA)before transseptal puncture,(2)in the left atrium(LA)through the transseptal sheath after transseptal puncture,(3)in the LA after removal of introducer sheath,and(4)in the RA after removal of introducer sheath.Transesophageal echocardiography was performed at three months to detect iASD.RESULTS Pressure in the RA increased significantly after removing the introducer sheath(P=0.034),whereas no difference was found in oxygen saturation in the RA(P=0.623).Pressure measurement in the LA showed no significant difference after re-moving the introducer sheath(P=0.718).Oxygen saturation in the LA also showed no significant difference(P=0.129).Follow-up transesophageal echocardiogram at 3 months revealed a persistent iASD in 4 patients(8.5%).CONCLUSIONS Our study suggests that iASD after percutaneous LAAO does not result in significant shunts directly after the procedure,although a significant increase of mean right atrial pressure can be observed.Persistent iASDs after percutaneous LAAO seem to be relatively rare at three months. | Ioannis Drosos Roberta De Rosa Philipp C.Seppelt Sebastian Cremer Silvia Mas-Peiro Katrin Hemmann Jana Oppermann Recha Blessing Mariuca Vasa-Nicotera Andreas M.Zeiher Zisis Dimitriadis | 2022 | Journal of Geriatric Cardiology2022，19，9： | 1 |

| 20 | Knockdown of apoptosis-inducing factor disrupts function of respiratory complex I显示文摘Recent findings suggest that apoptotic protein apoptosis-inducing factor (AIF) may also play an important non-apoptotic function inside mitochondria. AIF was proposed to be an important component of respiratory chain complex I that is the major producer of superoxide radical. The possible role of AIF is still controversial. Superoxide production could be used as a valuable measure of complex I function, because the majority of superoxide is produced there. Therefore, we employed superoxide-specific mitochondrial fluo- rescence dye for detection of superoxide production. We studied an impact of AIF knockdown on function of mitochondrial complex I by analyzing superoxide production in selected cell lines. Our results show that tumoral telomerase-positive (TP) AIF knockdown cell lines display significant increase in superoxide pro- duction in comparison to control cells, while a non-tumoral cell line and tumoral telomerase-negative cell lines with alternative lengthening of telomeres (ALT) show a decrease in superoxide production. According to these results, we can conclude that AIF knockdown disrupts function of complex I and therefore increases the superoxide production in mitochondria. The distinct effect of AIF depletion in various cell lines could result from recently discovered activity of telomerase in mitochondria of TP cancer cells, but this hypothesis needs further investigation. | MIROSLAV VAˇRECHA DANIELA PÁCLOVÁ JIˇRINA PROCHÁZKOVÁ PAVEL MATULA DUˇSAN CMARKO AND MICHAL KOZUBEK | 2012 | BIOCELL2012，36，3： | 0 |
