13. Effects of local alendronate administration on bone defect healing. Histomorphometric and radiological evaluation in a rabbit model
Abstract Purpose: To performed a histomorphometric and radiological study to evaluate the effects of alendronate sodium administered locally in mandibular bone defects created in rabbits. Methods: Two circular defects 5 mm in diameter were created bilaterally in the mandibular corpus of 20 New Zealand rabbits (i.e., four defects per animal). Each defect

14. Improving reproducibility and external validity. The role of standardization and data reporting of laboratory rat husbandry and housing
Abstract Purpose: To identify the most relevant flaws in standardization in husbandry practices and lack of transparency to report them. This review proposes some measures in order to improve transparency, reproducibility and eventually external validity in experimental surgery experiments with rat model. Methods: We performed a search of scientific articl

15. Sheep Model for Uterine Transplantation: The Best Option Before Starting a Human Program
OBJECTIVE: This study reports the first four cases of a uterine transplant procedure conducted in sheep in Latin America. The aim of this study was to evaluate the success of uterine transplantation in sheep. METHOD: The study was conducted at Laboratory of Medical Investigation 37 (LIM 37) at the University of São Paulo School of Medicine. Four healthy m

16. The efficacy of low-level 940 nm laser therapy with different energy intensities on bone healing
Abstract The aim of this study was to evaluate the efficacy of low-level 940 nm laser therapy with energy intensities of 5, 10 and 20 J/cm2 on bone healing in an animal model. A total of 48 female adult Wistar rats underwent surgery to create bone defects in the right tibias. Low-level laser therapy (LLLT) was applied immediately after surgery and on post-op

17. Can a graft be placed over a flap in complex hypospadias surgery? An experimental study in rabbits
ABSTRACT Purpose: To develop a rabbit experimental study to test the hypothesis that surgical repair of hypospadias with severe ventral curvatures might be completed in one stage, if a graft, such as buccal mucosa, could be placed over the tunica vaginalis flap used in corporoplasty for ventral lengthening, with the addition of an onlay preputial island fla

18. Validation of a new technique to freezing and embedding tissue in Mohs surgery, using an animal model
ABSTRACT PURPOSE: To validate the innovative Dry Ice method, comparing it with two standard methods currently used for tissue processing in Mohs surgery, the Heat Sink method and the Miami Special. METHODS: Forty eight samples of pigs kin with the standard beveled Mohs technique were used, and randomly allocated into six groups. Each group was processed wi

19. Specific training for LESS surgery results from a prospective study in the animal model
ABSTRACT Objective to prospectively evaluate the ability of post-graduate students enrolled in a laparoscopy program of the Institute for Teaching and Research to complete single port total nephrectomies. Materials and Methods 15 post-graduate students were enrolled in the study, which was performed using the SILStm port system for single-port procedures

20. A comparative study of the areas of osteochondral defects produced in femoral condyles of rabbits treated with sugar cane biopolymer gel
PURPOSE: To assess the histological response of damaged osteochondral tissue in the femoral condyles of rabbits after repairing the wounds with sugar cane biopolymer gel - compared to the control group. METHODS: The study investigated 16 New Zealand rabbits, at 90, 120 and 180 days after surgery. In all the animals, a lesion of 3.2 mm in diameter and 4 mm

21. Bioactive glass in cavitary bone defects: a comparative experimental study in rabbits
OBJECTIVES: To compare bioactive glass and autograft regarding their histomorphometric characteristics. METHODS: The authors conducted a prospective case-control experimental study on animals in order to compare the histomorphometric characteristics of bioactive glass versus autograft. Eight rabbits underwent surgery in which a cavitary defect was created i

22. Physical exercise prevents motor disorders and striatal oxidative imbalance after cerebral ischemia-reperfusion
Stroke is the third most common cause of death worldwide, and most stroke survivors present some functional impairment. We assessed the striatal oxidative balance and motor alterations resulting from stroke in a rat model to investigate the neuroprotective role of physical exercise. Forty male Wistar rats were assigned to 4 groups: a) control, b) ischemia, c
