INTRODUCTION This paper attempts to verify the anatomical veracity of the belief that in order to enter into a posterior calyx one must aim for the medial calyx during a percutaneous nephrolithotomy (PCNL). METHODS Volume rendered and maximum intensity projection reconstructions of normal pelvicalyceal systems were assessed in various rotational planes. An experienced urologist decided the ap...

Marine sponges harbouring uncultured symbiotic bacteria are important sources of biologically active compounds. Since they would be interesting resources to explore unknown functional genes by means of a metagenomic approach, we constructed a metagenomic library of the Japanese marine sponge Discodermia calyx. The functional screening afforded the two clones producing porphyrins as red pigments...

OBJECTIVE To present the results of upper calyceal access during percutaneous nephrolithotripsy (PCNL) for stones in the lower calyx, as PCNL is considered the most effective minimally invasive surgery for managing lower calyceal stones, with percutaneous access either directly to the lower calyx or through an upper or middle calyx. PATIENTS AND METHODS The study included 76 patients with sin...

a field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of roselle (hibiscus sabdariffa l.) in 2014/15 cropping season at wondo genet agricultural research center experimental site (at wondo genet station). two inter-row spacing (60 and 90 cm) and three intra-row spacing (30, 60 and 90 cm) were evaluated using two varieties, wg-hi...

at least on the lower surface, rarely glabrous; petioles ? ^ in. Bracteoles \ in., narrow?lanceolate, somewhat persistent. Panicles terminal, the racemes densely fulvous-villous, and congested. Ovary-sessile, young fulvous-villous. Calyx shortly constricted above the ovary then funnelshaped, hairy within and without; calyx-tube upwards 5-fluted, the segments triangular, acute, erect. Petals nar...

Odor discrimination in higher brain centers is essential for behavioral responses to odors. One such center is the mushroom body (MB) of insects, which is required for odor discrimination learning. The calyx of the MB receives olfactory input from projection neurons (PNs) that are targets of olfactory sensory neurons (OSNs) in the antennal lobe (AL). In the calyx, olfactory information is trans...

This paper presents a novel method to recognize stem calyx of an apple using shape descriptors. The main drawback of existing apple grading techniques is that stem calyx part of an apple is treated as defects, this leads to poor grading of apples. In order to overcome this drawback, we proposed an approach to recognize stem-calyx and differentiated from true defects based on shape features. Our...

Objective: A field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of roselle (Hibiscus sabdariffa L.) in 2014/15 cropping season at Wondo Genet Agricultural Research Center experimental site (at Wondo Genet station). Methods: Two inter-row spacings (60 and 90 cm) and three intra-row spacings (30,...

Calyx afferents, a group of morphologically and physiologically distinct afferent fibers innervating the striolar region of vestibular sensory epithelia, are selectively labeled by antibodies to the calcium-binding protein calretinin. In this study, the population of calretinin-stained calyx afferents was used to delineate and quantify the striolar region in six rodent species: mouse, rat, gerb...
