1. Comparison of Sharp Dissection, Electrocautery, and Ultrasonic Activated Scalpel with Regard to Endothelial Damage, Preparation Time, and Postoperative Bleeding During Radial Artery Harvesting
Abstract Objective: To examine the effects of classical technique, electrocautery, and ultrasonic dissection on endothelial integrity, function, and preparation time for harvesting the radial artery (RA) during coronary artery bypass grafting (CABG). Methods: Forty-five patients who underwent isolated CABG and whose RA was suitable for use were studied and

2. Leiomyosarcoma in a cockatiel
RESUMO: As calopsitas (Nymphicus hollandicus) são aves exóticas originárias da Austrália. Devido a beleza e capacidade de aprendizado são uma das principais aves utilizadas como animal de companhia. O objetivo deste trabalho foi relatar um caso de leiomiossarcoma, na musculatura umeral da asa esquerda de uma calopsita. O animal deu entrada no Núcleo d

3. Effect of topical ozonetherapy on gingival wound healing in pigs: histological and immuno-histochemical analysis
Abstract In this study, the effects of ozonetherapy on secondary wound healing were evaluated histologically and immuno-histochemically. Material and Methods: 8 healthy pigs were used in this study. Six wounds with 10 mm in diameter were created through the punch technique on the palatinal gingiva of each pig. Ozone gas was applied on only 3 wounds (test gro

4. Respiratory immunohistochemical study in rats exposed to cigarette smoke and alcohol
PURPOSE: To investigate the effects of exposure to cigarette and alcohol on immunohistochemical disorders caused by these attacks to respiratory system of rats.METHODS:Sixty male Wistar rats in four groups: control, cigarette smoke, alcohol and cigarette smoke + alcohol during 260 days. Immunohistochemistry was performed by researching survivin and protein P

5. The RANK/ RANKL/ OPG interaction in the repair of autogenous bone grafts in female rats with estrogen deficiency
The aim of this study was to evaluate the resorption process during the repair of autogenous bone grafts with or without coverage by an expanded polytetrafluoroethylene (e-PTFE) membrane in female rats with estrogen deficiency using the immunohistochemical technique. Eighty female rats were randomly divided into two groups (OVX and SHAM). The 40 female rats

6. Cell block technique as an additional tool in the diagnosis of ameloblastoma
The objective of this study was to evaluate the cytological content of ameloblastomas of the jaw. Nine cases of ameloblastoma were punctured, and the intralesional material was processed using the cell block technique. After centrifugation, the pellet obtained from the punctured material was fixed in formaldehyde and routinely processed to inclusion in paraf

7. Atividade gelatinolítica in situ e imuno-expressão das metaloproteinases 2 e 9 em lesões potencialmente malignas e carcinomas espinocelulares bucais / In situ gelatinolytic activity and immunoexpression of metalloproteinases 2 and 9 in oral potentially malignant lesions and squamous cell carcinomas
The transition from normal oral mucosa to invasive carcinoma has a complex and multifactorial etiology. Oral leukoplakia (OL) is regarded as the most prevalent potentially malignant oral lesion, with a higher tendency for malignant transformation if compared to normal oral mucosa. Although an increased activity of matrix metalloproteinases (MMPs) 2 and 9 in

8. Development of two potential diagnostic monoclonal antibodies against human cytomegalovirus glycoprotein B
Human cytomegalovirus glycoprotein B (gB) represents a target for diagnosis and treatment in view of the role it plays in virus entry and spread. Nevertheless, to our knowledge, rare detection of a gB antigen has been reported in transplant patients and limited information is available about diagnostic gB monoclonal antibodies (mAbs). Our aim was to develop

9. Tipos especiais histológicos de carcinomas da mama : perfil imunoistoquímico com ênfase na classificação molecular / Histological special types of breast carcinomas : immunohistochemical profile with emphasis on molecular classification
Most invasive breast carcinomas are classified as invasive ductal carcinoma, not otherwise specified (IDC-NOS), while approximately 25% are defined as special histological types (HST). These HST of breast carcinomas are categorized into at least 17 distinct pathological entities. Most studies in the literature regarding the molecular classification (luminal

Pesquisa de metaloproteinases de matriz utilizando a técnica de tissue microarray (TMA) / Urothelial carcinomas of the urinary bladder : morphological and immunohistochemical aspects. Expression of the matrix metalloproteinases using the tissue microarray (TMA) technique
OBJETIVOS: Estudar variáveis anatomopatológicas relacionadas à progressão tumoral em carcinomas uroteliais primários de bexiga e sua associação com a imunoexpressão de metaloproteinases de matriz (MMPs) - 2, -9 e -14 no epitélio e no estroma dos tumores primários e nas metástases linfonodais.

INTRODUCTION: Breast cancer is a leading cause of death among women all over the Word. Proliferative lesions of the breast are believed to be precursors of or markers of increased risk for breast carcinoma. Although the active research in the field of breast cancer, the early molecular events associated with cancer evolution and progression are still poorly

12. Immunohistochemical staining of Langerhans cells in HPV-positive and HPV-negative cases of oral squamous cells carcinoma
The Human Papillomavirus (HPV) has been strongly implicated in development of some cases of oral squamous cell carcinoma (OSCC). However, the immunological system somehow reacts against the presence of this virus. Among the cells involved in such mechanism of defense Langerhans cells (LC) stand out, which are responsible for processing and presenting antigen
