1. Cell cycle markers and apoptotic proteins in oral tongue squamous cell carcinoma in young and elderly patients
Abstract The immunoexpression of p16, p53, and Bax in oral tongue squamous cell carcinoma (OTSCC) in young and elderly patients is assessed based on clinical and morphological parameters. The sample consists of 60 OTSCC cases: 30 in young (age ≤ 45 years) and 30 in elderly (age ≥ 60 years) patients. Clinical (tumor size, regional node metastasis, distant

3. Eicosanoids and cancer
Eicosanoids are 20-carbon bioactive lipids derived from the metabolism of polyunsaturated fatty acids, which can modulate various biological processes including cell proliferation, adhesion and migration, angiogenesis, vascular permeability and inflammatory responses. In recent years, studies have shown the importance of eicosanoids in the control of physiol

4. Expression of CD90 and P75NTR stem cell markers in ameloblastomas: a possible role in their biological behavior
Abstract Multicystic and unicystic ameloblastomas are benign odontogenic tumors that present distinct biological behavior. The investigation of stem cells has become an important branch of tumor biology, with several studies addressing the possible role of these cells in tumor growth, angiogenesis, progression, infiltration and invasiveness. This study evalu

5. Effect of ozone oxidative preconditioning in preventing early radiation-induced lung injury in rats
Ionizing radiation causes its biological effects mainly through oxidative damage induced by reactive oxygen species. Previous studies showed that ozone oxidative preconditioning attenuated pathophysiological events mediated by reactive oxygen species. As inhalation of ozone induces lung injury, the aim of this study was to examine whether ozone oxidative pre

6. Angiogênese, células-tronco neoplásicas CD34+ e sinvastatina em modelo de carcinogênese mamária induzida quimicamente / Angiogenesis, CD34+ cancer stem-cells and simvastatin in a chemically induced mammary carcinogenesis model
Breast cancer is the most common malignancy and the leading cause of death from cancer among females worldwide. Despite all the research and all the progress achieved so far, the morbidity and mortality due to this cancer remains high in patients at advanced stages. Recently, it was described a new model of carcinogenesis in which stem cells (SC) could be re

7. Análise do fenômeno da imunotolerância na fotocarcinogênese em lábio / Analysis of the immunotolerance phenomenon of in the lip photocarcinogenesis
Ultraviolet radiation (UV) is the main cause of non-melanoma skin cancer and induces biological effects that promote photocarcinogenesis by causing mutations directly on DNA. However, there seems to be an indirect effect, which induces immunosuppession. The physiological phenomenon of immune tolerance, which is responsible for the prevention of autoimmune di

8. Quantitative study of FAS ligand expression on gastric mucosa of rats submited to oxidative stress by Azoxymethane / Estudo quantitativo na expressão de FAS ligante pós indução de estresse oxidativo em mucosa gástrica com administração de azoximetano, em ratos
Objetivo: Estudar quantitativamente a expressão da proteína ativadora de apoptose FAS ligante (FAS-L) na mucosa gástrica de ratos submetidos à exposição ao Azoximetano (AOM). Métodos: Ratos Wistar (n=56) divididos em 2 grupos: G1, controle (n=28), e G2, AOM (n=28), recebendo injeções subcutâneas de solução salina (1 mL/Kg) ou AOM (5 mg/Kg), respe

9. Predição de malignidade de tumores ovarianos utilizando marcadores tumorais, índice de risco e ROMA / Prediction of malignancy of ovarian tumors using tumor markers, risk index and ROMA
BACKGROUND: Ovarian cancer is the most lethal of all gynecological cancers and requires to be treated by gynecologic oncologists in tertiary centers accustomed to treating this disease to achieve the best prognosis. This study aims to compare four different strategies to predict the benignity or malignancy of pelvic tumors presumably of ovarian origin using,

Polysaccharides of higher plants form complex structures and multiple intermolecular interactions. They are noted for their immune system activities, being classified as exogenous modifiers of biological responses. However, the spectrum of activities is very large including the antiviral, antitumor, immunostimulant, anti-inflammatory, anticoagulant and antic

11. Analysis of angiogenic factors and cyclooxygenase-2 expression in cartilaginous tumors: clinical and histological correlation
OBJECTIVES: To study the role of angiogenesis and cyclooxygenase-2 expression in cartilaginous tumors and correlate these factors with prognosis. INTRODUCTION: For chondrosarcoma, the histological grade is the current standard for predicting tumor outcome. However, a low-grade chondrosarcoma can follow an aggressive course-as monitored by sequential imaging

12. Tumor banks: the cornerstone of basic research in urology
PURPOSE: Tumor banks have the primary responsibility for collecting, cataloging, storing and disseminating samples of tissues, cells and fluids, which are used by researchers to identify diagnostic molecular markers, prognostic indicators and therapeutic targets. The objective of this review was to describe a simple, reliable and reproducible protocol for ob
