1. Complex Re-do robotic pyeloplasty using cryopreserved placental tissue: an adjunct for success
ABSTRACT Introduction and Objectives: Management of recurrent ureteropelvic junction obstruction (UPJO) following pyeloplasty presents a challenging clinical problem. Failure of initial pyeloplasty is, in part, secondary to ureteral devascularization and subsequent fibrosis. In this video, we present a case of an anastomotic augmentation with cryopreserved

2. Effect of In Ovo Feeding of L-Glutamine to Chick Embryos
ABSTRACT In ovo feeding (IOF), injecting nutrients into the amnion of the avian embryo may enhance hatchability, gastrointestinal development and serum metabolism changes. This hypothesis was evaluated with 5 IOF solutions containing L-glutamine. Were used 315 fertile Rhode Island Red eggs were used (breeders with 32-weeks). The experimental design was compl

3. Viabilidade microbiológica de membrana amniótica bovina armazenada por 48 meses em glicerina 99% em temperatura ambiente
RESUMO O meio de armazenamento dos tecidos biológicos tem grande importância para que os mesmos possam ser empregados da melhor forma em cirurgias. A glicerina tem se mostrado eficiente, considerando aspectos microbiológicos, em armazenar alguns tecidos por períodos prolongados. Porém, nunca foi avaliada a conservação da membrana amniótica bovina em

4. Desenvolvimento placentário em quatis: evolução filogenética em carnívoros? / Placental development in quati: phylogenetic evolution in carnivores?
The importance of preservation of brazilian wild species is based on knowledge of their distribution, behavior in the wild and in captivity, and the detailed description of their reproductive biology in order to perpetuate the specie. One of the main impacts of this study is the scientific details of the uterine environment versus the process of placentation

5. Analysis of the dynamic of origin and fate of trophoblast cells in the maternal-fetal interface of pregnant guinea pig uterus to elucidate inverted yolk sac organization / Análise da dinâmica da origem e destino das células trofoblásticas na interface materno-fetal do útero gestante do cobaio na elucidação da organização da placenta vitelina invertida
A implantação embrionária e a placentação em cobaios são caracterizadas pela presença trofoblastos que se destacam da placenta principal, semelhantes ao trofoblasto extra-viloso de humanos. Nestes animais ultrapassam os limites, e podem ser encontrados infiltrados no profundamente no endométrio e no em ambiente externo ultrapassando aos limites da pa

6. Tratamento cirurgico do pterigio primario : comparação entre as tecnicas de rotação de retalho conjuntival e transplante de membrana amniotica / Surgical treatment of the primary pterrygium : comparison between rotation of conjunctival flap and amniotic membrane transplant
Objetivo: Determinar se o transplante de membrana amniótica é um procedimento mais eficaz que a rotação de retalho conjuntival, no tratamento cirúrgico de pterígio primário, quanto à taxa de recidiva. Material e métodos: Foi realizado um estudo prospectivo, do tipo ensaio clínico randomizado, de 228 pacientes (228 olhos) com pterígio primário gra

7. Caracterização das membranas fetais em búfalas no terço inicial da gestação
Este estudo visou à caracterização das membranas fetais em búfalas (Bubalus bubalis, Linnaeus 1758) no terço inicial da gestação. As membranas fetais foram analisadas macroscópica e microscopicamente (luz e microscopia eletrônica de transmissão). O córion possui uma camada simples de células circulares, com núcleos de forma esférica, denominada

8. Development placental in bovines obtained by natural gestation and by in vitro fertilization / Desenvolvimento placentário em bovinos obtidos por gestações naturais e por fecundação in vitro
The main goal of this study was to describe morphology and the early gestational development of 15 to 70 day-old bovine embryos obtained by natural mating and 35 day-old bovine embryos obtained by in vitro fertilization (IFV) technique. One hundred and forty-one concepts originated by natural mating and seven by IVF technique were used. All concepts were dis

9. Placentation in rock cavies, Kerodon rupestris (Wied, 1820) / Placentação em mocós, Kerodon rupestris Wied, 1820
Placentation studies of fourteen rock cavy females in different gestation phases were conducted. Females were pre-anesthetized associating ketamine chloridrate (15mg/kg) and midazolan (1mg/kg). Soon afterwards, they were anesthetized by isoflurane inhalation in association with oxygen at 100% saturation. After anesthesia, the surgery allowed to exhibit fetal

10. Differentiation potential of rat amnion.
The differentiation potential of rat amnion was investigated by explantation to different extrauterine sites and by culturing in vitro. Amnion differentiated into full skin by a process that is morphologically indistinguishable from normal skin development (interactions of the surface embryonic ectoderm and underlying mesenchyme). This process is not depende

11. JC human papovavirus replication in human amnion cells.
JC human papovavirus was found to replicate in primary human amnion cells. The virus has undergone eight passages in amnion cells and was identified by serological methods as JC virus. By restriction endonuclease analysis of the viral DNA, the fragments observed were identical to those previously reported for the prototype strain.

12. Abundant expression of parathyroid hormone-related protein in human amnion and its association with labor.
In animal models, parathyroid hormone-related protein (PTHrP) increases placental calcium transport and inhibits contraction of uterine smooth muscle. The present studies were undertaken to characterize the expression of PTHrP in human uteroplacental tissues. PTHrP mRNA was identified by Northern analysis as a single species (approximately 1.8 kilobases) in
