25. Minimally traumatic alveolar ridge augmentation with a tunnel injectable thermo-sensitive alginate scaffold
Injectable bone substitutes and techniques have been developed for use in minimally invasive procedures for bone augmentation. Objective : To develop a novel injectable thermo-sensitive alginate hydrogel (TSAH) as a scaffold to induce bone regeneration, using a minimally invasive tunnelling technique. Material and Methods : An injectable TSAH was prepared fr

26. Combined polyglycolic acid tube and autografting versus autografting or polyglycolic acid tube alone. A comparative study of peripheral nerve regeneration in rats
PURPOSE: To compare sciatic nerve regeneration in rats using three different techniques of repair.METHODS:Fifteen isogonics rats were divided into three groups according to the method used to repair a 5-mm long defect created in the sciatic nerve: autogenous graft (Group A), polyglycolic acid tube (PGAt) (Group B), and of the association of PGAt with the gra

27. Evaluation of the application of enemas containing sucralfate in tissue content of neutral and acid mucins in experimental model of diversion colitis
PURPOSE:To evaluate the effects of sucralfate on tissue content of neutral and acids mucins in rats with diversion colitis.METHODS: Thirty-six rats were submitted to a proximal right colostomy and a distal mucous fistula. They were divided into two groups according to sacrifice to be performed two or four weeks after intervention. Each group was divided into

28. Histological study of rat ovaries cryopreserved by vitrification or slow freezing and reimplanted in the early or late postmenopausal stage
PURPOSE: To compare two rat ovary cryopreservation techniques (vitrification vs. slow freezing) and two postmenopausal stages (early vs. late) with regard to graft take.METHODS:Thirty-three Wistar rats were submitted to bilateral oophorectomy. One ovary was submitted to histological analysis while the other was cryopreserved by slow freezing or vitrification

29. An experimental model of chronic rhinosinusitis in rabbits without bacterial inoculation
PURPOSE: Evaluate and compare two different experimental techniques of maxillary sinus ostium occlusion using N-butyl cyanoacrylate in developing chronic histological findings without the inoculation of pathogenic bacteria among rabbits.METHODS: In a randomized study, sixteen New Zealand rabbits were assigned for occlusion of the right maxillary sinus throug

30. Can Doppler or contrast-enhanced ultrasound analysis add diagnostically important information about the nature of breast lesions?
OBJECTIVES: Despite evidence suggesting that Doppler ultrasonography can help to differentiate between benign and malignant breast lesions, it is rarely applied in clinical practice. The aim of this study was to determine whether certain vascular features of breast masses observed by duplex Doppler and color Doppler ultrasonography (before and/or after micr

31. Immunohistochemical detection of virus through its nuclear cytopathic effect in idiopathic interstitial pneumonia other than acute exacerbation
Idiopathic interstitial pneumonias include complex diseases that have a strong interaction between genetic makeup and environmental factors. However, in many cases, no infectious agent can be demonstrated, and these clinical diseases rapidly progress to death. Theoretically, idiopathic interstitial pneumonias could be caused by the Epstein-Barr virus, cytome

32. The use of morphological and histological features as nutritional condition indices of Pagrus pagrus larvae
Morphometrical and histological techniques were employed to characterize Pagrus pagrus larvae nutritional condition. Larvae were reared in laboratory under controlled conditions with the main objective of testing whether these methodologies allowed finding differences between larvae from different feeding treatments. Once yolk was consumed (three days after

33. Giant multicystic cystadenoma of Cowper's gland: a case report
Main findings We report what to our knowledge is the first case of a giant multicystic cystadenoma of the Cowper's glands. An otherwise healthy 41-year-old man presented with acute urinary retention. Physical examination showed a perineal mass. Different imaging techniques demonstrated a multicystic tumor and en bloc excision was performed. Histological eva

34. Morfohistología testicular de Ceratophrys ornata (Bell) (Amphibia, Anura, Ceratophryidae)
This paper describes the morphohistological features of the testes of adult Ceratophrys ornata (Bell, 1843) (n = 5) from a wetland agroecosystem of central Argentina. The testes were processed by routine histological techniques, sectioned at 8 µm. The sheets obtained were stained with hematoxylin-eosin and Masson trichrome. The gonads are paired, yellowish,

35. Evaluation of wound healing activity of atranorin, a lichen secondary metabolite, on rodents
The aim of this study was to investigate the wound healing activity of atranorin cream (Patent requested) on excision wounds. Seventy-two male rats were anesthetized and an excisional wound was performed. Then the rats were randomly assigned into three groups: untreated control group; atranorin 1 (group treated with 1% AT ointment); and atranorin 5 (group tr

36. Determinação do impacto do oversizing da endoprótese sobre a aorta torácica. Estudo experimental em porcos / Impact of stent-graft oversizing on the thoracic aorta: experimental study in a porcine model
Introduction: The use of endovascular techniques to treat the various disorders of the aorta has supplanted traditional open techniques, and is particularly promising in trauma1. The traumatic rupture of the aorta is the second leading cause of death by traffic accident2, 3, and repair of these lesions with endoluminal stents has showed lower mortality and p
