1. Lesions in 224 spleens of splenectomized dogs and evalution of alternative techniques for previous microscopic diagnosis
RESUMO: Rotineiramente, frente à detecção de uma lesão proliferativa esplênica, médicos veterinários costumam optar pela esplenectomia antes de se obter o diagnóstico definitivo da lesão esplênica, o que pode trazer consequências deletérias ao cão. O mais apropriado seria, contudo, a sua adoção, como medida terapêutica, apenas nos casos com c

2. A procedure for correcting the position of plant tissue samples in accidentally polymerized glycol methacrylate resin
RESUMO A resina glicol-metacrilato é um meio de inclusão de grande conveniência no estudo histológico e citológico, nos mais variados tipos de tecido. Oferece excelente suporte mecânico no seccionamento de amostras, mesmo nas com grandes diferenças de dureza, e permite uma ampla gama de colorações e testes histoquímicos. Durante a etapa de infiltra

3. Expression of E-cadherin and involucrin in leukoplakia and oral cancer: an immunocytochemical and immunohistochemical study
Abstract To assess the immunocytochemical and immunohistochemical correlation of adhesion (E-cadherin) and cell differentiation (involucrin) molecules in oral leukoplakia and oral squamous cell carcinoma. Cytological samples and biopsies were obtained from male and female patients aged over 30 years with oral leukoplakia (n = 30) and oral squamous cell carci

4. Increasing diagnostic effectiveness of thyroid nodule evaluation by implementation of cell block preparation in routine US-FNA analysis
ABSTRACT Objective Ultrasound-guided fine-needle aspiration (US-FNA) biopsy has proven to be an accurate and efficient tool in thyroid nodule evaluation. We evaluated whether cell block adds to the diagnostic accuracy of US-FNA. Subjects and methods Three hundred twenty-eight consecutive patients underwent US-FNA, cytology and cell block evaluation. Six

5. Rastreamento da displasia anal em pacientes infectados pelo HIV: há concordância entre o estregaço anal e a biópsia guiada por anuscopia de alta resolução? / Screening anal dysplasia in HIV-infected patients : is there an agreement between anal pap smear and high resolution anoscopy guided biopsy?
OBJETIVO: O objetivo deste estudo foi analisar a concordância entre o esfregaço anal e a biópsia guiada por anuscopia de alta resolução no diagnóstico da displasia anal em pacientes infectados pelo HIV. MÉTODO: Conduzimos uma análise transversal de pacientes infectados pelo HIV submetidos a rastreamento de displasia anal rotineiro. A concordância en

6. Predictive success factors for ct-guided fine needle aspiration biopsy of pulmonary lesions
OBJECTIVE: Computed tomography-guided percutaneous fine needle aspiration biopsy of lung lesions is a simple, safe and reproducible procedure. Currently, it is widely used to diagnose lung lesions. However, different factors can influence the success rates of this procedure. The purpose of this study was to determine the influence of radiological and procedu

7. Adequabilidade dos esfregaços cervicais frente aos principais fatores pré-laboratoriais que podem interferir na análise do exame citopatológico. / Adequacy of cervical smears before the main factors pre-lab that can interfere with the analysis of cervical screening.
Background: Cervical cancer in Brazil has one of the highest incidence rates. Screening this neoplasia is effective when a cytopathological test stained by Papanicolaou method is performed. However, the quality of cytopathological samples directly influences the screening effectiveness. Eventhough, this method has been criticized due to the high rates of fal

8. Differential gene expression and mitotic cell analysis of the drought tolerant soybean (Glycine max L. Merrill Fabales, Fabaceae) cultivar MG/BR46 (Conquista) under two water deficit induction systems
Drought cause serious yield losses in soybean (Glycine max), roots being the first plant organ to detect the water-stress signals triggering defense mechanisms. We used two drought induction systems to identify genes differentially expressed in the roots of the drought-tolerant soybean cultivar MG/BR46 (Conquista) and characterize their expression levels dur

10. American visceral Leishmaniasis: a case report
Visceral leishmaniasis is a zoonotic disease caused by parasites of the Leishmania genus. Dog is the major source of infection to man, especially in urban areas. The authors report a case of visceral leishmaniasis in a pit bull female dog from Bocaina, São Paulo, Brazil. The animal presented clinical signs compatible with leishmaniasis, including skin lesio

12. NÃmeros cromossÃmicos de loranthaceae e viscaceae ocorrentes no nordeste brasileiro
Chromosome number, interphase nuclear structure, pattern of prophase chromosome condensation and meiotic behavior were investigated in 14 Brazilian species of Loranthaceae and Viscaceae families. All species showed reticulated interphase nuclei and uniform pattern of prophase chromosome condensation. The three genere of Loranthaceae studied had 2n=16 and the
