Classification of Chimney EVAR-Related Endoleaks: Insights from the PERICLES Registry

2017

Juxtarenal aortic aneurysms (JAAs) pose significant challenges for endovascular aneurysm repair (EVAR). A short or absent infrarenal neck typically excludes standard EVAR as a viable or reasonable treatment option. In this context, the use of chimney grafts (chEVAR) is gaining in popularity and applicability. These grafts are designed to course in the aortic lumen outside the main stent-graft to maintain normal perfusion to the involved target branches. As such, they may represent a promising and less resource-intensive option for management of JAAs. However, this technical strategy is not without challenges of its own, particularly the inevitable creation of “gutters” that result from the …

Glicerīna transportsistēmas un Hog1 loma raugu šūnu dzīvotspējas saglabāšanā anhidrobiozes stāvoklī

2015

Šī darba mērķis bija izpētīt glicerīna transportsistēmu un Hog1p iespējamo lomu raugu šūnu dzīvotspējas saglabāšanā anhidrobiozes stāvoklī. Lai sasniegtu šo mērķi, izmantoja raugu Saccharomyces cerevisiae BY4741 un tā izogēnos celmus, kuriem trūka viens vai vairāki gēni, kuri ir atbildīgi par glicerīna transportiera Stl1p, glicerīna eksporta kanāla Fps1p un regulatorās Hog1p MAP kināzes ekspresiju raugu šūnās. Darbam bija izvirzīti sekojošie uzdevumi: izpētīt S. cerevisiae BY4741 spējas pāriet anhidrobiozes stāvoklī; novērtēt glicerīna transportsistēmu Stl1p un Fps1p, ka arī Hog1p ietekmi uz raugu šūnu rezistenci pret dehidratāciju; izpētīt raugu spējas pārdzīvot osmotisko stresu un šīs ied…
