1. Standardization of organoid culture for evaluation of melanogenesis induced by UVB, UVA and visible light,
Abstract Background: Organoid cultures are primary cultures that maintain architectural characteristics and the relationships between cells, as well as the extracellular matrix. They are alternatives for pathophysiological or therapeutic investigation rather than animal and in vitro tests. Objective: Development of a cutaneous organoid culture model, aimin

2. Comparison of two soft tissue substitutes for the treatment of gingival recession defects: an animal histological study
Abstract Objectives: This study aimed to compare two different soft tissue replacement grafts in their ability to treat gingival recession defects and successfully integrate with the surrounding tissues. Methodology: Nine beagle dogs were included and followed up to 10 weeks. Sites for intervention were allocated to one of the grafting materials investigat

3. Appendicular origin and structure of the spur of Vochysiaceae flowers
ABSTRACT Floral nectaries are linked with animal pollinators and floral specialization, characterizing some plant groups, such as the mostly Neotropical Vochysiaceae. The phylogeny of these plants has been revised based on molecular data, but their conspicuous spurs were mostly neglected. The appendicular or receptacular origin of these spurs has been discus

4. Functional investigation of bone implant viability using radiotracers in a new model of osteonecrosis
OBJECTIVES: Conventional imaging methods are excellent for the morphological characterization of the consequences of osteonecrosis; however, only specialized techniques have been considered useful for obtaining functional information. To explore the affinity of radiotracers for severely devascularized bone, a new mouse model of isolated femur implanted in a

5. Effect of mitochondrial potassium channel on the renal protection mediated by sodium thiosulfate against ethylene glycol induced nephrolithiasis in rat model
Purpose: Sodium thiosulfate (STS) is clinically reported to be a promising drug in preventing nephrolithiasis. However, its mechanism of action remains unclear. In the present study, we investigated the role of mitochondrial KATP channel in the renal protection mediated by STS. Materials and Methods: Nephrolithiasis was induced in Wistar rats by administra

6. Analysis of the effects of topical renal hypothermia on lung tissue after kidney ischemia and reperfusion in rats
PURPOSE: To evaluate whether topical renal hypothermia (TRH) at different levels of temperature has protective effects on lung tissue after renal I/R, through an analysis of organ histology and inflammatory markers in lung tissue. METHODS: Twenty-eight male Wistar rats were randomly allocated across four groups and subjected to renal ischemia at different l

7. Avaliação da cicatrização cutânea: fluorescência e estereologia / Evaluation of skin healing: fluorescence and stereology
Objetivos: Recentemente, a Espectroscopia de Fluorescência (EF) tem sido estudada como método de análise de propriedades da pele de forma nãoinvasiva e em tempo real, utilizada em uma variedade de aplicações, incluindo avaliação e diagnóstico do tecido in vivo. Contudo, na cicatrização da pele, essa técnica não tem sido completamente explorada.

8. Efeitos do inseticida endossulfam sobre a morfologia e a morfometria testicular em morcegos frugívoros Artibeus lituratus (OLFERS, 1818) / Effects of the endosulfan on the testicular morphology and morphometry in fruit bats Artibeus lituratus (OLFERS, 1818)
Large amounts of agricultural chemicals are discharged into the environment in Brazil. These pesticides are often used to destroy or impair the activity of organisms that attack crops. There are some reports in the literature concerning the decline of many wildlife populations as a result of contamination of their habitats by pesticides. One of the putative

9. Animal models of prenatal immune challenge and their contribution to the study of schizophrenia: a systematic review
Prenatal immune challenge (PIC) in pregnant rodents produces offspring with abnormalities in behavior, histology, and gene expression that are reminiscent of schizophrenia and autism. Based on this, the goal of this article was to review the main contributions of PIC models, especially the one using the viral-mimetic particle polyriboinosinic-polyribocytidyl

10. Hypoxia/reoxygenation-induced myocardial lesions in newborn piglets are related to interindividual variability and not to oxygen concentration
OBJECTIVE: Evaluation of myocardial histological changes in an experimental animal model of neonatal hypoxiareoxygenation. METHODS: Normocapnic hypoxia was induced in 40 male Landrace/Large White piglets. Reoxygenation was initiated when the animals developed bradycardia (HR <60 beats/min) or severe hypotension (MAP <15 mmHg). The animals were divided into f

11. Mecanismos celulares e teciduais da regeneração em holotúrias (Echinodermata:Holothuroidea) / Cellular and tecidual mechanisms of regeneration in sea cucumbers (Echinodermata: Holothuroidea)
Equinodermos são bem conhecidos pelas suas grandes capacidades regenerativas, principalmente em processos mais complexos como a reposição de membros e órgãos. Porém pouco se sabe sobre processos aparentemente mais simples como a cicatrização. Tem sido descrito que um dos principais mecanismos envolvidos neste evento é o remodelamento da matriz extra

12. CRIOPRESERVAÇÃO DE TECIDO OVARIANO CAPRINO: EFICIÊNCIA DE DIFERENTES AGENTES CRIOPROTETORES / OVARIAN TISSUE CRYOPRESERVATION GOAT: EFFICIENCY OF DIFFERENT CRYOPROTECTIVE AGENTS
The cryopreservation of ovarian tissue has been the target of intense study with the purpose of assisting in the technology of assisted reproduction in animals and humans. For the success of cryopreservation, the composition of the freezing solution, especially the intracellular cryoprotectant agent used is of fundamental importance. Thus, this study aimed t
