OBJECTIVE We aimed to investigate the effect of pelvicaliceal anatomical differences on the etiology of lower caliceal stones. MATERIALS AND METHODS Records of adult patients between January 1996 and December 2005 with solitary lower caliceal stone were reviewed. After exclusion of patients with hydronephrosis, major renal anatomic anomalies, non-calcium stones, history of recurrent stone dis...

The localization and density of voltage-gated Ca(2+) channels at active zones are essential for the amount and kinetics of transmitter release at synapses. RIM proteins are scaffolding proteins at the active zone that bind to several other presynaptic proteins, including voltage-gated Ca(2+) channel α-subunits. The long isoforms of RIM proteins, which contain NH2-terminal Rab3- and Munc13-inter...

Introduction: Physalis alkekengi (Solanaceae) is a rich source of various antioxidants. There are some reports that show P. alkekengi has been used for treatment of a wide range of diseases including gout and inflammation. Xanthine oxidase plays a crucial role in gout. Many natural compounds such as various flavonoids have been reported to have inhibitory effect on xanthine oxidase. Metho...

The attractiveness of a plant to pollinators is dependent on both the number of flowers produced and the size of the petals. However, limiting resources often result in a size/number trade-off, whereby the plant can make either more flowers or larger flowers, but not both. If developmental genes underlying sepal and petal identity (some of which overlap) also influence size, then this shared ge...

Species that express the inflated calyx syndrome (ICS) are found in several genera of the Solanaceae. The MADS-box protein MPF2, together with the plant hormones cytokinin and gibberellin, has been shown to be responsible for this trait in Physalis floridana. We have used sequence data from 114 species belonging to 35 genera to construct a molecular phylogeny of Solanaceae. Apart from the 2 Wit...

This article describes the cellular sources for tyramine and the cellular targets of tyramine via the Tyramine Receptor 1 (AmTyr1) in the olfactory learning and memory neuropils of the honey bee brain. Clusters of approximately 160 tyramine immunoreactive neurons are the source of tyraminergic fibers with small varicosities in the optic lobes, antennal lobes, lateral protocerebrum, mushroom bod...

The innervation patterns of vestibular saccular afferents were quantitatively investigated in pigeons using biotinylated dextran amine as a neural tracer and three-dimensional computer reconstruction. Type I hair cells were found throughout a large portion of the macula, with the highest density observed in the striola. Type II hair cells were located throughout the macula, with the highest den...

Caliceal diverticulum is a rare disorder in which a urine-filled cavity is connected to the renal calix by a narrow isthmus. Treatment of caliceal diverticulum varies depending on the complications, which include recurrent kidney infections, hematuria, and symptomatic calculi. The use of sonography may be insufficient for accurately diagnosing this condition; contrast urography, CT, or both als...

  Phelipanche pouyanii is described here as a new species from South Khorassan Province, East of Iran. Its diagnostic morphological features are the calyx teeth being far longer than the calyx tube and staminal filaments being glabrous. These characters clearly differentiated the new species from its closely related taxa, i.e., P. mutelii, P. angustelaciniata and P. nana. Results obtained from...
