Role of cyclic nucleotide phosphodiesterase isoenzymes in contractile responses of denuded rat aorta related to various Ca 2+ sources
2001
We have examined the cyclic nucleotide phosphodiesterase isoforms (PDE) involved in the contractile response of rat aorta to different agonists and different experimental procedures for use in functional studies. The inhibitory effect of AAL 05 on the different PDEs isolated from bovine aortic smooth muscle was examined. Compound AAL 05 appeared to be a selective PDE3 inhibitor. We analyzed the ability of the non-selective inhibitor IBMX (3-isobutyl-1-methylxanthine) and the isoenzyme selective inhibitors nimodipine (type 1), AAL 05 (6-(N-methyl-N-cyclohexyl butyl carboxamide) quinolin-2-one) and SKF 94120 (5-(4-acetamidophenyl) pyrazin-2(1H)-one; type3), rolipram (type4) and zaprinast (typ…
Pro-Inflammatory Genetic Markers of Atherosclerosis
2013
Atherosclerosis (AS) is a chronic, progressive, multifactorial disease mostly affecting large and medium-sized elastic and muscular arteries. It has formerly been considered a bland lipid storage disease. Currently, multiple independent pathways of evidence suggest this pathological condition is a peculiar form of inflammation, triggered by cholesterol-rich lipoproteins and influenced both by environmental and genetic factors. The Human Genome Project opened up the opportunity to dissect complex human traits and to understand basic pathways of multifactorial diseases such as AS. Population-based association studies have emerged as powerful tools for examining genes with a role in common mul…
Genetic susceptibility to the coronary artery diseases
2016
The origin of coronary arterydisease is the interaction between genetic predisposition and environmental influences.
Cis-epistasis at the LPA locus and risk of cardiovascular diseases.
2022
AIMS Coronary artery disease (CAD) has a strong genetic predisposition. However, despite substantial discoveries made by genome-wide association studies (GWAS), a large proportion of heritability awaits identification. Non-additive genetic-effects might be responsible for part of the unaccounted genetic variance. Here we attempted a proof-of-concept study to identify non-additive genetic effects, namely epistatic interactions, associated with CAD. METHODS AND RESULTS We tested for epistatic interactions in ten CAD case-control studies and UK Biobank with focus on 8,068 SNPs at 56 loci with known associations with CAD risk. We identified a SNP pair located in cis at the LPA locus, rs1800769 …
Cohort profile: the cardiovascular risk in Young Finns Study.
2008
In Finland, coronary heart disease (CHD) incidence was very high in the 1960s and 1970s. In line with this high incidence, the Seven Countries Study showed that the level of serum cholesterol in Finns was also the highest among the investigated countries in the 1960s. Because several studies indicated that the atherosclerotic process starts early in life, and in accord with the World Health Organization Recommendation of 1978 which stated that studies assessing atherosclerosis precursors in children should be initiated, a program was launched in Finland in the late 1970s to study cardiovascular risk in the youth. The Cardiovascular Risk in Young Finns Study was designed as a collaborative e…

Study of the ability of apolipoprotein C1 to inhibit cholesteryl ester transfer protein activity in normolipidemic and hyperlipidemic patients with c…
2013
High cholesteryl ester transfer protein (CETP) activity was found to accelerate the progression of atherosclerosis. Apolipoprotein C1 (apoC1) is a potent physiological inhibitor of CETP. ApoC1 operates as CETP inhibitor through its ability to modify the electrostatic charge at the lipoprotein surface. The inhibitory potential of apoC1 has never been studied in high risk patients or in patients with hyperlipidemia. Our aim was to address the functionality of apoC1 as CETP inhibitor in normo- and hyperlipidemic patients with documented coronary artery disease and in patients with type 1 and type 2 diabetes in comparison with normolipidemic-normoglycemic healthy subjects. We confirmed that apo…
Preclinical report on allogeneic uterus transplantation in non-human primates
2013
Study question Is it possible to perform allogeneic uterus transplantation (UTx) with a donation from a live donor in a non-human primate species and what immunosuppression is needed to prevent rejection? Summary answer Allogeneic UTx in the baboon is a donor- and recipient-safe surgical procedure; immunosuppression with induction therapy and a triple protocol should be used. What is known already UTx may become a treatment for absolute uterine factor infertility. Autologous UTx models have been developed in non-human primates with reports on long-term survival of the uterine grafts. STUDY DESIGN, SIZEAND DURATION: This experimental study included 18 female baboons as uterus donors and 18 f…
Isolierter Verschluss einer zilioretinalen Arteriole - Klinik und Verlauf in 31 Fällen
2012
Hintergrund: Untersuchung des Krankheitsverlaufs dieses seltenen Typs eines retinalen Arteriolenverschlusses in einem grosen Patientenkollektiv. Patienten und Methoden: Die Krankenblattunterlagen aller Patienten, die an der Augenklinik der Universitatsmedizin Mainz (Germany) im Zeitraum 1/1998 bis 12/2009 angiografisch mit isoliertem zilioretinalem Arteriolenverschluss (ZRAV) diagnostiziert wurden, wurden retrospektiv ausgewertet. Standardtherapie war eine intravenose Antikoagulation mit Heparin. Mediane Nachbeobachtungszeit 51 Monate. Ergebnisse: In die Studie eingeschlossen wurden 31 Augen von 31 Patienten (Altersmedian 49 Jahre, Range 25 − 71 Jahre). Signifikante Karotidsklerose in 17/31…
Antithrombotische Therapie bei peripherer arterieller Verschlusskrankheit
2018
Was ist neu? Antithrombotische Therapie bei stabiler PAVK Die aktuellen deutschen und europäischen Leitlinien empfehlen bei Patienten mit einer peripheren arteriellen Verschlusskrankheit (PAVK) die Monotherapie mit einem Thrombozytenaggregationshemmer (ASS 100 mg oder Clopidogrel 75 mg).In der COMPASS (Cardiovascular OutcoMes for People using Anticoagulation StrategieS) -Studie wurde Patienten mit PAVK 2 × 2,5 mg Rivaroxaban zusätzlich zu ASS 100 mg gegeben. Dies führte zur signifikanten Reduktion kardiovaskulärer Ereignisse (MACE = Major Adverse Cardiovascular Events) wie kardiovaskulärer Tod, Myokardinfarkt und Schlaganfall. Ebenfalls signifikant reduziert wurden periphere Ereignisse (MAL…
