1. Citomegalovírus, herpesvírus humano 6, herpesvírus humano 7 e perfil imunofenotípico do infiltrado inflamatório na periodontite crônica marginal / Cytomegalovirus, human herpesvirus 6, human herpesvirus 7 and immunophenotypic profile of inflammatory infiltrate in marginal chronic periodontitis
Human chronic periodontitis is an inflammatory process characterized by dense accumulation of immune cells in the periodontal tissue. The periodontitis can lead to loss of teeth in the patient and the pathogenesis of this disease is not completely known. This study tested the hypothesis that cells within inflammatory infiltrate can harbor betaherpesviruses a

2. Modulação da expressão de conexinas na retina: um estudo morfológico, bioquímico e funcional. / Modulation of connexin expression in retina: a study using morphological, biochemical and functional approaches.
Life is a dynamic process in time and space, resulting from an interaction provided by gap junctions (GJs), channels composed of connexins (Cxs) that permits the passage of molecules up to 1kDa and ions. The aim of this study was analyze the modulation of Cxs during development, dark adaptation and after local mechanical trauma in the retina using techniques

3. Indice de massa corporal, padrão de distribuição de gordura corporal e expressão de receptores hormonais em mulheres com carcinoma de mama invasivo
Objective: to evaluate the relation between body parameters used to define central obesity -waist circumference (WC) and waist to hip ratio (WRH)- and steroid receptor status in breast carcinomas of pre- and postmenopausal women. Subjects and methods: This is a cross-sectional study on 473 women with breast malignancies stage I-III, treated at the National C

4. Estudo da pele humana fotoenvelhecida após tratamento com terapia fotodinâmica associada ao ácido 5-delta-aminolevulínico tópíco: avaliação imunoistoquímica, do colágeno e do tecido elástico / Study of photo aged human skin after photodynamic therapy treatment with topic 5 delta aminolevulinic acid: immunohistochemical, colagenous and elastic fibre analysis.
PDT is nowadays considered one of the therapies for photo-aging, since it gives a satisfactory response for both, aesthetic result as well as treating and preventing pre-malignous lesions that are a frequent outcome of photo-aged skin. The selective destruction of target tissue occurs through a chemical reaction, by using a photosensitizing agent exposed to

5. O MODELO DESMIELINIZANTE DO BROMETO DE ETÍDIO (BE): ESTUDOS MORFOLÓGICOS EM CAMUNDONGOS C57BL/6 NORMAIS E KNOCKOUT PARA CONEXINA 32 / ETHIDIUM BROMIDE (EB) DEMYELINATING MODEL: MORPHOLOGIC STUDIES IN C57BL/6 NORMAL AND CX 32 KNOCKOUT MICE
Light and ultraestructural changes of central and peripheral nervous system lesions in mice KO for connexin-32 and submitted to the ethidium bromide gliotoxic demyelinating model are described. Their KO condition was tested with PCR and a negative connexin-32 labelling was performed by immunofluorescence. The experimental animals were C57BL/6 normal mice and

6. Estudo epidemiolÃgico e imunohistoquÃmico com BAX, BCL-2 E P27 em carcinoma espinocelular invasivo da boca / Epidemiological and immunohistochemical study with BAX, BCL-2 and P27 in invasive oral squamous cell carcinoma
The evaluation of the expression of bax, bcl-2 and p27 proteins at invasive squamous cell carcinoma of oral cavity was done using the immunohistochemistry technique to know about apoptotic profile of these neoplasms. The epidemiological factors and the clinical behavior of the patients were detected, too. Statistical parameters different from odds ratio was

8. Immunohistochemistry analysis of osteosarcoma in patients with and without metastasis and its prognosis correlation / "Análise imunohistoquímica do osteossarcoma em pacientes com e sem metástases e sua correlação prognóstica"
We study, by imunohistochemistry technique, the proteins p53, MDM-2, c-Kit, ErbB-2, PCNA and p-glycoprotein in samples of osteosarcoma tumors at diagnosis and its correlation with the prognosis of this patients. The p-53 was positive in 23,1% (9/39), PCNA in 71,4% (25/35), p-glycoprotein in 40,5% (15/37), MDM-2 in 34,8% (8/23), c-kit in 67,8%(25/37) and ErbB

9. Estudo comparativo da pele pré- e pós-quimioabrasão para tratamento de rítides da região perioral: avaliação clínica e imuno-histoquímica / Chemabrasion for perioral wrinkles treatment: clinical and immunohistochemical an alysis of the skin
Atualmente existem vários tratamentos para melhorar a aparência da pele com fotoenvelhecimento. A quimioabrasão é uma dessas técnicas, consiste na associação de esfoliação química com ácido tricloroacético a 35%, seguida por dermabrasão. O ácido tricloroacético facilita a dermabrasão por promover coagulação das proteínas da pele, tornando-

10. Estereologia, imuno-histoquímica e microscopia eletrônica de varredura na análise da reação tecidual a implantes de discos de adesivo dentinário fotoativado, hidróxido de cálcio e cimento de ionômero de vidro: estudo experimental em ratos / Stereology, imunohistochemistry, and scanning electron microscopy in the analysis of tissue reaction to disks implants of light-cured dentin adhesive, calcium hydroxide, and glass ionomer cement: experimental study in rats
Purpose: to evaluate the biocompatibility of some pulpar protecting materials in the subcutaneous tissue of rats along the time. Methods: standardized implants of Calcium Hydroxide (CH), Glass Ionomer Cement (GIC) and Light-cured Dentin Adhesive (LDA) surgically were put in the back of Wistar rats and left by 15 and 30 days (each group with 5 animals) and th
