Mitochondrien - Permeabilität
Journal of Clinical and Basic Cardiology 2002; 5 (1): 29-41
Pyruvate protects the heart against reperfusion injury through inhibiting MPTP opening and enhancing subsequent pore closure. Pore opening upon reperfusion was determined using the entrapment of pre-loaded 3H-DOG, whilst subsequent closure of the MPTP was detected by measuring the entrapment of 3H-DOG loaded after maximal recovery of the heart (post-loading). These protocols are illustrated in the Figure and further details are given in the text and reference [97] from where the data are taken. Keywords: Diagramm,

The Mitochondrial Permeability Transition - A Pore Way for the Heart to Die
Mitochondrien - Apoptose
Journal of Clinical and Basic Cardiology 2002; 5 (1): 29-41
The release of mitochondrial proteins plays a central role in the initiation of apoptosis. An apoptotic signal leads to the release of pro-apoptotic proteins located within the intermembrane space between the inner and outer mitochondrial membranes (IMM and OMM) into the cytosol. The pathway for release may be OMM rupture following opening of the MPTP and mitochondrial swelling, or through recruitment of specific pore-forming proteins to the outer
membrane such as Bax and t-Bid. Release is inhibited by Bcl-2. The released cytochrome binds to Apaf-1 that proteolytically activates caspase 9 which in turn activates caspase 3 and so initiates
the apoptotic cascade. Caspases are inhibited by endogenous inhibitors which are themselves inactivated by Smac (or DIABLO) that is also released along with apoptosis inducing factor (AIF).
This migrates to the nucleus where it causes chromatin condensation and DNA fragmentation. Further details are given in the text. Keywords: Apoptose,

Magnesiumefflux - Atrium
Journal of Clinical and Basic Cardiology 2002; 5 (1): 5-22
Preliminary measurements of Mg2+ efflux from cultured atrial cells. The background solution contained in mmol/l: Na+, 155; K+, 5; Ca2+, 0.9; and no added Mg2+, buffered to pH 7.4 with 5 mmol/l HEPES. After 6 minutes the cell pellet was added to the background solution. Because of contamination this increased the [Mg2+] from around 15 micromol/l to 60 micromol/l. Addition of adrenaline caused an efflux of Mg2+ from the cells. The electrode did not react to 30 micromol/l adrenaline Keywords: Atrium,

Schematischer Zusammenhang zwischen Leptinfreisetzung durch Adipozyten im Fettgewebe, seine hypothalamische Bindung und Freisetzung von Neuropeptid Y, welches Hungergefühl vermindert und das Sättigungsgefühl steigert. Leptin hat darüber hinaus eine starke stimulatorische Aktivität auf die GnRH-Freisetzung und damit auf die Pulsatilität des GnRH Pulsgenerators. Zusätzlich sind Lipolyse und Liogenesefaktoren dargestellt Keywords: Fertilität,
