Neurotransmission involves the exo-endocytic cycling of synaptic vesicles (SVs) within nerve terminals. Exocytosis is facilitated by a cytomatrix assembled at the active zone (AZ). The precise spatial and functional relationship between exocytic fusion of SVs at AZ membranes and endocytic SV retrieval is unknown. Here, we identify the scaffold G protein coupled receptor kinase 2 interacting (GI...

Recent studies indicate that active zones (AZs)-sites of neurotransmitter release-may be assembled from preassembled AZ precursor vesicles inserted into the presynaptic plasma membrane. Here we report that one putative AZ precursor vesicle of CNS synapses-the Piccolo-Bassoon transport vesicle (PTV)-carries a comprehensive set of AZ proteins genetically and functionally coupled to synaptic vesic...
Összefoglalás – A városi hősziget (UHI) mérésével kapcsolatos irodalom áttekintése széleskörű ellentmondásokat tár fel a hősziget erősségének számszerűsítéséhez felhasznált városi és külterületi mérési helyeknek az értelmezésében és osztályozásában. Bizonyított, hogy ezeknek az eltéréseknek a gyökere a városklimatológia tér-osztályozási rendszerében régóta fennálló paradigmában, a városi-külter...
In vivo changes in the cytosolic pH of abscission zone (AZ) cells were visualized using confocal microscopic detection of the fluorescent pH-sensitive and intracellularly trapped dye, 2',7'-bis-(2-carboxyethyl)-5(and-6)-carboxyfluorescein (BCECF), driven by its acetoxymethyl ester. A specific and gradual increase in the cytosolic pH of AZ cells was observed during natural abscission of flower o...
Sphingolipids, found in membranes of eukaryotic cells, have been demonstrated to carry out functions in various processes in plant cells. However, the roles of these lipids in fruit abscission remain to be determined in plants. Biochemical and fluorescence microscopy imaging approach has been adopted to investigate the accumulation and distribution of sphingolipids during mature-fruit abscissio...
OBJECTIVE To assess the effect of acetazolamide (Az) on exercise performance during early acclimatization to altitude. METHODS Az (250 mg twice daily) or placebo was administered for 3 days in a double-blind, randomized manner followed by a rapid ascent to 3459 m in the Italian Alps. Twenty healthy adults (age range, 18-67 years) were tested at 60% of sea-level peak power output for 15 minute...
