13. Ultrasound - guided access during percutaneous nephrolithotomy: entering desired calyx with appropriate entry site and angle
ABSTRACT Objectives: To evaluate the success of ultrasonography directed renal access in entering the target calyx from proper entry site and in the direction of renal pelvis during percutaneous nephrolithotomy (PCNL). Materials and Methods: PCNL cases who were operated on by one fellow from May-June 2014 were included in this study. A vertically placed ul

14. Minimally invasive percutaneous nephrolithotomy guided by ultrasonography to treat upper urinary tract calculi complicated with severe spinal deformity
ABSTRACT Objective: To report our experience of minimally invasive percutaneous nephrolithotomy(MPCNL) in managing upper urinary tract calculi complicated with severe spinal deformity. Materials and Methods: Between August 2001 to December 2012, 16 upper urinary calculi in 13 patients with severe spinal deformity were treated by MPCNL. Preoperative investi

15. Comparative anatomy of calyx and foliar glands of Banisteriopsis C. B. Rob. (Malpighiaceae)
Banisteriopsis is considered one of the largest genera of Malpighiaceae with 58 species, of which 47 occur in Brazil. The typical calyx and leaf glands of Banisteriopsis are considered relevant to the adaptive success of Malpighiaceae. Comparative studies of anatomical and histochemical characteristics may reveal similarities and assist in the interpretation

16. Percutaneous puncture of renal calyxes guided by a novel device coupled with ultrasound
ABSTRACT Purpose: To evaluate the efficiency of a novel device coupled with ultrassound for renal percutaneous puncture. Materials and Methods: After establishing hydronephrosis, ten pigs had three calyxes of each kidney punctured by the same urology resident, with and without the new device ("Punctiometer"). Time for procedure completion, number of attemp

17. A Novel method of ensuring safe and accurate dilatation during percutaneous nephrolithotomy
ABSTRACT Objective: To report our technique that helps locate the guidewire into the ureter enabling safe dilatation during PCNL. Materials and Methods: Cases in which the guidewire failed to pass into the ureter following successful puncture of the desired calyx were subjected to this technique. A second guidewire was passed through the outer sheath of a

18. The skin-to-calyx distance measured by renal ct scan and ultrasound
PurposeWe developed a stereotactic device to guide the puncture for percutaneous nephrolithotripsy, which uses the distance from the target calyx to its perpendicular point on skin (SCD) to calculate the needle´s entry angle. This study seeks to validate the use of measurements obtained by ultrasound (US) and computerized tomography (CT) for needle´s entry

19. Cyclodipeptides from metagenomic library of a japanese marine sponge
A metagenômica independente de cultura é um meio atraente e promissor para explorar pequenas moléculas bioativas únicas de esponjas marinhas que abrigam micro-organismos simbiontes não cultiváveis. Foi realizada uma triagem funcional da biblioteca metagenômica da esponja marinha japonesa Discodermia calyx. O fracionamento bio-guiado do extrato cultiva

20. Predicting calyceal access for percutaneous nephrolithotomy with computed tomography multiplanar reconstruction
OBJECTIVES: Objective parameters in computed tomography (CT) scans that could predict calyceal access during percutaneous nephrolithotomy have not been evaluated. These parameters could improve access planning for percutaneous nephrolithotomy. We aimed to determine which parameters extracted from a preoperative multiplanar reconstructed CT could predict ren

21. Desenvolvimento e morfologia da flor em espécies da tribo Dipterygeae (Leguminosae, Papilionoideae) / Floral development and morphology in species of Dipterygeae (Papilionoideae - Leguminosae)
Espécies da tribo Dipterygeae apresentam morfologia floral interessante, em especial o cálice, bem diferente dos demais membros de Papilionoideae. Representantes desta tribo exibem cálice assimétrico, constituído por duas sépalas adaxiais muito grandes e livres, e três sépalas unidas na base, com lobos abaxiais em forma de pequenos dentes. Assim, est

22. Explorando as interações hospedeiro-parasitoide para a identificação de moléculas com potencial biotecnológico / Exploiting the host parasitoid interactions for the identification of molecules with biotechnological potential
Parasitoides criam condições favoráveis para seu desenvolvimento regulando processos fisiológicos do hospedeiro via a utilização de moléculas produzidas por tecidos maternos ou por tecidos derivados do parasitoide imaturo ou de simbiontes associados (vírus de poliDNA - PDV). Assim, essas moléculas se destacam como uma fonte preciosa para o desenvolv

23. Malanea revolutifolia (Guettardeae: Rubiaceae), una nueva especie del noreste de Brasil
Malanea revolutifolia, a new species from the Atlantic forest of northeastern Brazil is described and illustrated, with a key to differentiate some related Brazilian species. M. revolutifolia is similar to M. forsteronioides and M. microphylla, but is distinguished by its elliptical, strongly revolute leaves (2.8-7.5 × 2-3.5 cm), a deeply divided calyx, lob

24. When prone position is contraindicated or not preferable, can supine percutaneous nephrolithotomy solve the problem?
PURPOSE: To assess safety and efficacy of supine percutaneous nephrolithotomy in patients for whom prone position or general anesthesia is contraindicated or not preferable due to associated comorbidities, overweight or ipsilateral upper ureteric calculi. MATERIALS AND METHODS: Fifty two patients (37 males and 15 females, mean age 33 ± 10.2 years) were incl
