RESUMO A divergência genética de genótipos de melão do grupo momordica foi estimada, coletados em cinco estados brasileiros, e determinada a contribuição relativa dos caracteres morfológicos avaliados para a variabilidade genética. Foi adotado o delineamento de blocos casualizados com quatro repetições. Nesse estudo, foram utilizados 19 acessos de melão do grupo momordica, dois acessos do grupo cantaloupensis e duas cultivares comerciais do grupo inodorus. Esses genótipos foram caracterizados por meio de 42 descritores morfológicos. Os dados foram submetidos aos métodos de agrupamento de Tocher e UPGMA a partir da matriz de dissimilaridade genética de Mahalanobis (D2). Foi utilizado o critério de Singh, para identificar a contribuição relativa de cada caráter para a divergência genética. Obtiveram-se quatro grupos de similaridade em ambas as técnicas multivariadas utilizadas, havendo concordância entre os métodos hierárquicos UPGMA e de agrupamento de Tocher. Os caracteres, tamanho da cicatriz do pistilo, teor de sólidos solúveis, comprimento da semente, comprimento de fruto e comprimento do cotilédone contribuíram com aproximadamente 53,86% para a divergência genética entre os genótipos.

ABSTRACT The genetic divergence of melon genotypes belonging to momordica group, collected in five Brazilian States, was estimated, and the relative contribution of the morphological characters was determined for the genetic variability. The experimental design was randomized blocks, with four replicates. We evaluated 19 accessions of melon, momordica group, two accessions of cantaloupensis group and two commercial cultivars of inodorus group. These genotypes were characterized by 42 morphological descriptors. The data were submitted to Tocher and UPGMA grouping methods using the genetic dissimilarity matrix, using Mahalanobis’ distance. Singh criterion was used to identify the relative contribution of each character to the genetic divergence. Four groups of similarity were obtained in both multivariate techniques, with agreement between hierarchical UPGMA and Tocher grouping methods. The characters: pistil scar size, soluble solid content, seed length, fruit length and cotyledon length contributed with approximately 53.86% to genetic divergence among genotypes.

O coentro é uma hortaliça bastante apreciada como condimento. Em Pernambuco, a cultivar Verdão é uma das mais plantadas, porém um dos problemas dessa cultivar tem sido o seu pendoamento precoce. Cultivares com maior período de crescimento vegetativo e tolerantes ao pendoamento precoce têm sido procuradas pelos produtores. Entretanto, são poucas as pesquisas realizadas no Brasil com cultivares de coentro com essas características. Uma alternativa seria identificar populações promissoras para obtenção de linhagens adaptadas ao calor dentro da cultivar Verdão, uma vez que essa cultivar apresenta ciclo curto e variabilidade genética para este caráter. O objetivo deste trabalho foi estimar parâmetros genéticos e predizer o valor genético de progênies de meio-irmãos de coentro pela metodologia dos modelos lineares mistos (procedimento REML/BLUP) quanto aos caracteres número de dias para início do pendoamento, altura de plantas, diâmetro do caule e massa fresca, além de estimar o número mínimo de progênies adequado para representar uma população de coentro derivada da cultivar Verdão. Oitenta e cinco progênies de meio-irmãos do segundo ciclo de seleção recorrente foram conduzidas em dois experimentos. Foram obtidas estimativas de herdabilidade altas e relações CVg/CVe superiores à unidade para todos os caracteres avaliados, exceto para altura de plantas. A estimativa de parâmetros genéticos permitiu concluir que as progênies de coentro apresentam variabilidade genética para os caracteres número de dias para início do pendoamento, diâmetro do caule e massa fresca. O número mínimo de progênies adequado para estimar os parâmetros genéticos e representar a população de coentro é de 68. Treze progênies de meio-irmãos podem ser selecionadas para dar continuidade ao programa de melhoramento de coentro para tolerância ao calor.

Coriander is a vegetable crop very appreciated as a condiment. The cultivar Verdão is one of the most cultivated in the state of Pernambuco (Brazil), however it is susceptible to premature bolting. Cultivars with longer vegetative growth and tolerant to early bolting have been sought by producers. Nevertheless, a few studies are conducted in Brazil on coriander cultivars with such characteristics. An alternative would be the identification of promising populations to obtain lineages adapted to heat within the cultivar Verdão, since this cultivar has a short cycle and genetic variability for this characteristic. The aim of this study was to estimate the genetic parameters and predict the genetic value of half-sib coriander progenies by the methodology of mixed linear models (REML/BLUP procedure) regarding the characters number of days to the beginning of bolting, plant height, stem diameter and fresh weight. Besides estimating the minimum number of suitable progenies to represent a coriander population derived from the cultivar Verdão. Eighty-five half-sib progenies of the second cycle of recurrent selection were conducted in two experiments. The estimation of high heritability and the CVg/CVe ratio above the unit for all traits were obtained, except for plant height. The estimation of genetic parameters showed that coriander progenies exhibit genetic variability for the characters number of days to the beginning of bolting, stem diameter and fresh weight. The minimum number of suitable progenies to estimate genetic parameters and to represent the coriander population is 68 progenies. Thirteen half-sib progenies may be selected to carry on the coriander breeding program regarding heat tolerance.

Introduction Guillain-Barre syndrome is an acute neuropathy that rarely compromises bladder function. Conservative management including clean intermittent catheterization and pharmacotherapy is the primary approach for hypocompliant contracted bladder. Surgical treatment may be used in refractory cases to improve bladder compliance and capacity in order to protect the upper urinary tract. We describe a case of pure laparoscopic augmentation ileocystoplasty in a patient affected by Guillain-Barre syndrome. Presentation A 15-year-old female, complaining of voiding dysfunction, recurrent urinary tract infection and worsening renal function for three months. A previous history of Guillain-Barre syndrome on childhood was related. A voiding cystourethrography showed a pine-cone bladder with moderate post-void residual urine. The urodynamic demonstrated a hypocompliant bladder and small bladder capacity (190mL) with high detrusor pressure (54 cmH2O). Nonsurgical treatments were attempted, however unsuccessfully. The patient was placed in the exaggerated Trendelenburg position. A four-port transperitoneal technique was used. A segment of ileum approximately 15-20cm was selected and divided with its pedicle. The ileal anastomosis and creation of ileal U-shaped plate were performed laparoscopically, without staplers. Bladder mobilization and longidutinal cystotomy were performed. Enterovesical anastomosis was done with continuous running suture. A suprapubic cystostomy was placed through a 5mm trocar. Results The total operative time was 335 min. The blood loss was minimal. The patient developed ileus in the early days, diet acceptance after the fourth day and was discharged on the seventh postoperative day. The urethral catheter was removed after 2 weeks. At 6-month follow-up, a cystogram showed a significant improvement in bladder capacity. The patient adhered well to clean intermittent self-catheterization and there was no report for febrile infections or worsening of renal function. We did not experience any complication related to the intestinal anastomosis fully prepared intracorporeally. Conclusions Albeit technically challenging, pure laparoscopic enterocystoplasty was feasible and safe. Preparing the enteral anastomosis and the pouch intracoporeally may prolong surgical time and contribute to postoperative ileus. Surgical staplers can assist in the procedure, however they are not essential.
