Hemangioma of the renal calyx is a rare disease, which is difficult to diagnose and an even greater challenge to treat. We report the use of the new-generation flexible ureteroscope, in the management of a 37-year-old Asian male with a lower pole renal calyx hemangioma, which was previously inaccessible.

Precise regulation of synaptic vesicle (SV) release at the calyx of Held is critical for auditory processing. At the prehearing calyx of Held, synchronous and asynchronous release is mediated by fast and slow releasing SVs within the readily releasable pool (RRP). However, the posthearing calyx has dramatically different release properties. Whether developmental alterations in RRP properties co...

The sensitivity of posttetanic potentiation (PTP) to high-frequency stimulation (HFS) steeply decays during the first 2 postnatal weeks. We investigated the underlying mechanisms for the developmental change of PTP induced by HFS (100 Hz, 2 s) at postnatal days 4-6 and 9-11 at the rat calyx of Held synapse. Low-concentration tetraphenylphosphonium (2 μM), an inhibitor of mitochondrial Na(+)/Ca(...

12 Developmental changes in Ca 2+ clearance and short-term plasticity 13 14 15 Abstract 26 27 The sensitivity of post-tetanic potentiation (PTP) to high frequency stimulation (HFS) steeply decays during 28 the first two postnatal weeks. We investigated the underlying mechanisms for the developmental change of PTP 29 induced by HFS (100 Hz, 2 sec) at postnatal days 4-6 and 9-11 at the rat calyx ...

We made flattened neuroepithelial preparations of horizontal and vertical (anterior and posterior) cristae from mouse, rat, gerbil, guinea pig, chinchilla, and tree squirrel. Calretinin immunohistochemistry was used to label the calyx class of afferents. Because these afferents are restricted to the central zone of the crista, their distribution allowed us to delineate this zone. In addition to...

Endoparasitic wasps are able to develop inside permissive host insects due to their ability to overcome or evade the host's immune system. In the present study, we provide experimental evidence that ovarian calyx fluid of the ichneumonid endoparasitoid Venturia canescens has the potential to alter host haemocyte spreading and inhibit host haemolymph melanisation due to the presence of a putativ...

22 23 Familial hemiplegic migraine type-1 (FHM1) is caused by missense mutations in the CACNA1A 24 gene that encodes the α1A pore-forming subunit of CaV2.1 Ca channels. We used knock-in (KI) 25 transgenic mice harbouring the pathogenic FHM-1 mutation R192Q to study neurotransmission at the 26 calyx of Held synapse and cortical layer 2/3 pyramidal cells (PCs). Using whole cell patch clamp 27 rec...
