Activity of Sodium Ion, Potassium Ion in the Epididymis of the Rat
… activity along the cytoplasmic side of the plasmalemma of the ductal epithelial cells. The most intense deposition of reaction products was found on the plasmalemma delimiting the lower lateral and basal regions of non-ciliated cells. The plasma membranes in the apical regions of the cells …

Estudio de los flujos netos simultáneos de H+ y K+ y la actividad redox en raíces aeropónicas estériles de plántulas de girasol (Helianthus annuus L.)
… roots. Both fluxes are not related directly. The plasmalemma redox activity was too measured and their relation with the H+ y K+ fluxes.

ROLE OF ACID SPHINGOMYELINASE IN ICAM-1/NHE1-DEPENDENT ENDOCYTOSIS: IMPLICATIONS IN LEUKOCYTE TRANSMIGRATION
… sphingomyelinase and ceramide. This supports plasmalemma deformability and cytoskeleton rearrangement, bridging these events to the formation of endothelial docking structures and vesicles involved in leukocyte transmigration.

Elektrophysiologische Untersuchungen an einzelligen marinen Riesenalgen
… Darstellung der elektrischen Eigenschaften von Plasmalemma und Tonoplast durch gezielte Manipulation des vakuolären und externen Mediums. Dabei kann der für die Physiologie der Zellen wichtige hydrostatische Innendruck (Turgor) ständig kontrolliert werden. Die Applikation eines Ladungspulses …

Charakterisierung regulatorischer Schritte in der konstitutiven Exocytose in Pflanzenzellen
… den Einbau oder die Wegnahme von Membran aus dem Plasmalemma widerspiegeln müssen. Die Verwendung transgener hypersekretorischer Tabakzellen ermöglicht neben der Messung der Exocytoserate die Bestimmung der Syntheserate sekretorischen Proteins.Mit diesen beiden Parametern ist es möglich den …

Physiological and ultrastructural effects of sterol-inhibiting fungicides on apple leaves and the apple scab fungus
… Invaginations and proliferations of the plasmalemma were observed as well as increased vacuolization of the cell. Further electron microscopic observations were made of the in vitro conidial state of Venturia inaequalis following the application of fenarimol. Conidia treated 2 hours with …

Membrane properties and calcium ion activity in skeletal muscle fibres of the dystrophic mouse
… to investigate the properties of skeletal muscle plasmalemma and calcium ion movements during muscle wastage, with the intention of determining the route of calcium influx, and the efficacy of calcium ion blockers in preventing this influx. Electrophysiological parameters (Resting membrane …

Modeling and Ion Mapping of Intracellular Calcium Distribution in Molluscan Neural Somata
… (lipochondria) exist in large numbers at the plasmalemma of these neurons. Ion images of the neurons processed by freeze-substitution showed that the nucleus consistently contains less calcium than the cytoplasm. These results suggest that in these neurons, the calcium buffering capacity of …

Membrane Surface Charge and Lipid Signaling in Phagocytosis
… surface charge of the inner leaflet of the plasmalemma. The unique negativity of the inner aspect of the plasma membrane serves to attract and anchor key signaling and effector molecules that are required to initiate phagosome formation. Conversely, the loss of charge that accompanies …

How to Mend a Broken Heart: Massive Endocytosis and the Role of Lipidic Forces in Membrane Trafficking
… within the outer lipid monolayer of the plasmalemma or through coupled calcium-mediated fusion and phosphatidylinositol 4,5-bisphosphate (PIP2) signaling. Both forms of MEND do not rely on classical endocytic proteins such as clathrin or dynamin and appear independent of the cytoskeletal …

The daily rhythm of Paneth cells in <i>Mus musculus </i>
… or that are in the cytoplasmic leaflet of the plasmalemma, usually do not (Jakoi <em>et al</em> 1976).</p> <p>Fine electron dense lines of unknown function and composition are visible in the halo. In mature secretory granules, these lines seem to radiate from the core (Fig. 12). At other times, …

Soybean mosaic virus: strains, ultrastructure and movement
… The pinwheels were frequently opposed to the plasmalemma and were associated with plasmodesmata and plasmalemmasomes. Endoplasmic reticulum was associated with the base of those pinwheels found in the cytoplasm. The early stage of SMV pinwheel formation appeared to be similar to that reported …

The Membrane Polypeptides of the Vacuolar System: Composition and Recycling
… with PL, were now randomly dispersed over the plasmalemma. At this time, analysis of PM captured by a second phagocytic load revealed the presence of all labeled species originally present in the PL membrane. This demonstrated the rapid, synchronous centrifugal flow of PL polypeptides to the …

Salt stress responses in pear and quince: physiological and molecular aspects
… NHX1 (tonoplast Na+/H+ antiporter), SOS1 (plasmalemma Na+/H+ antiporter) and HKT1 (K+ high-affinity and Na+ low-affinity transporter). These studies showed that two quince rootstocks adopted different responsive mechanisms to NaCl stress. BA29 increased its Na+ sequestration activity into …

GENOMIC TOOLS TO IMPROVE PEACH (P. PERSICA L. BATSCH) RESILIENCE TO CLIMATE CHALLENGES
… a water potential gradient through the plasmalemma increasing the osmotic concentration inside and leading to cell dehydration resulting in the coagulation of the protoplasm. Flower buds are hardiest during the winter, when they are fully dormant. During dormancy the lack of active xylem …
