13. Action potential propagation into the presynaptic dendrites of rat mitral cells.
1. Dendritic patch-clamp recordings were obtained from mitral cells in rat olfactory bulb slices, up to 350 microns from the soma. Simultaneous dendritic and somatic whole-cell recordings indicated that action potentials (APs) evoked by somatic or dendritic current injection were initiated near the soma. Both the large amplitude (100.7 +/- 1.1 mV) and the sh

17. Analysis of a long-duration inhibitory potential in mitral cells in the isolated turtle olfactory bulb.
1. An inhibitory potential of long duration has been analysed in intracellular recordings from mitral cells in the isolated turtle olfactory bulb preparation. 2. A single volley in the olfactory nerves or lateral olfactory tract elicited synaptic inhibition in mitral cells, followed by a long-lasting hyperpolarization of the cell. This slow potential has bee

18. Analysis of synaptic potentials in mitral cells in the isolated turtle olfactory bulb.
1. The synaptic responses of mitral cells have been analysed in intracellular recordings from the isolated olfactory bulb of the turtle. 2. The response of a mitral cell to a single volley in the lateral olfactory tract consisted of and antidromic impulse and a complex hyperpolarizing potential that had the properties of an inhibitory post-synaptic potential

19. Chronic haemolysis after Lillehei-Kaster valve replacement. Comparison with the findings after Björk-shiley and Starr-Edwards mitral valve replacement.
Nineteen female and sixteen male patients who have had their heart valves replaced with Lillehei-Kaster valves were investigated for haemolysis four to 18 months after operation. Investigation included serum lactic dehydrogenase, serum haptoglobins, and urine haemosiderin. Red cells survival, using autologous red cells labelled with 51Cr, was measured in 12

20. Fenfluramine Disrupts the Mitral Valve Interstitial Cell Response to Serotonin
Serotonin (5HT) receptor signaling and 5HT-related agents, such as the anorexogen fenfluramine (Fen), have been associated with heart valve disease. We investigated the hypothesis that Fen may disrupt mitral valve interstitial cell (MVIC) homeostasis through its effects on mitogenesis and extracellular matrix biosynthesis. Normal and myxomatous mitral valves

21. GABAA and glutamate receptor involvement in dendrodendritic synaptic interactions from salamander olfactory bulb.
1. Whole-cell patch clamp and optical recording techniques were applied to the same in vitro salamander olfactory bulb preparations to study the postsynaptic responses of single mitral/tufted cells in the context of the surrounding neural activity in which they are embedded. Mitral/tufted cells were identified by intracellular filling with biocytin. 2. Singl

22. Mechanisms governing dendritic γ-aminobutyric acid (GABA) release in the rat olfactory bulb
In the olfactory bulb, synaptic transmission between dendrites plays an important role in the processing of olfactory information. Glutamate released from the dendrites of principal mitral cells excites the dendritic spines of granule cells, which in turn release γ-aminobutyric acid (GABA) back onto mitral cell dendrites. Slow N-methyl-d-aspartate (NMD

23. Red blood cell abnormalities in cardiac valvular disease
Nineteen patients with morphological abnormalities of the red blood cells are described, and these formed approximately 3% of the total cases of cardiac valvular disease. In two patients the abnormal blood film developed after the insertion of an aortic and mitral valve prosthesis respectively, but in another two patients the abnormal blood film was correcte

24. Haemolysis related to mitral valve replacement with the Beall valve prosthesis
Henderson, B. J., Mitha, A. S., le Roux, B. T., and Gotsman, M. S. (1973).Thorax, 28, 488-491. Haemolysis related to mitral valve replacement with the Beall valve prothesis. Experience of valve replacement with the Beall compressed Teflon disc valve in 59 patients confirms that the incidence of clinically significant late red cell destruction is high. An app
