13. Análises citogenéticas e expressão da telomerase em sarcoma 180
The cancer is a result of genetic instability. There are two theorical lines which try to explain this pathology origin, the conventional genetic theories and the chromosomal theory of cancer. A lot of neoplastic cell characteristics cant be explained by the conventional theories and they are explained by the chromosomal theory. The telomerase plays an impor

14. Molecular study of cellular adhesion genes in bladder cancer / Estudo molecular de genes envolvidos com adesão celular em câncer de bexiga
Introduction: Bladder cancer is the fifth neoplasm in Western countries, whose occurrence is 336,000 new cases annually, and also being responsible for 132,000 deaths in the worldwide. The incidence of bladder tumors in Brazil were 7,550 cases in 1999, representing 2,8% of overall diagnosed cancer in both gender. One of the main therapeutic challenges is ide

15. Avaliação da eficacia de diferentes compostos nos modelos in vitro e in vivo da leishmaniose sob diferentes condições de oxigenio / Efficacy of different compounds in leishmaniasis in vitro and in vivo models under different oxygen tensions
L. amazonensis, a species transmitted mainly in the Amazon region, which is associated with localized cutaneous lesions and chemotherapy remains the mainstay for the control of leishmaniasis, as effective vaccines have yet to be developed. In this context, there is an intense search for potential new synthetic compounds and natural products for the treatment

16. Expression of USP2a and study of its interaction with clathrin in human oral squamous carcinoma and prostate cancer cells / Estudo da expressão da enzima desubiquitinante USP2a e de sua interação com a proteina clatrina em celulas derivadas de carcinomas espinocelulares bucais e de prostata humanos
The ubiquitin (Ub)-proteasome pathway controls cellular protein turnover by degrading targeted intracellular proteins tagged with poly-Ub chains. Ubiquitination is a reversible process and the deubiquitinating enzymes (DUBs) are proteases that specifically cleave off Ub from Ub-protein conjugates. They can act in a preproteasomal level removing the poly-Ub t

17. Estudo retrospectivo-sistemático e análise quantitativa da proliferação celular e apoptose; identificação da proteína conexina 43 e 26 aberrante em glândula perianal normal, hiperplásica e neoplásica em cães / Retrospective - systematic study and quantitative analysis of the cellular proliferation and apoptosis and identification of connexin 43 and aberrant 26 protein in normal, hyperplasic and neoplastic perianal glands in dogs
Two hundred and forty five neoplasms of the perianal glands of dogs from the archives of the Department of Pathology of the FMVZ/USP, 1984 to 2004, have been reviewed hystologically. Most of the cases (34%) were classified as moderately differentiated adenomas, group II, in males over 8 years of age, which showed an androgenic dependence of these neoplasms.

18. Antiulcerogenic effect of Chlorella vulgaris extract / Efeito anti-ulcerogenico do extrato de Chlorella vulgaris
About 10%of the world?s population suffer from peptic ulcer, within this percentage we find thousands of Brazilians. This pathology is caused by an unbalance between the protection and attack mechanisms of the stomach lining, and is the result of the association of various endogenous attack factors (pepsin, acid, bile), exogenous factors pertaining to life s

19. Neuroprotection by flavonoids
The high morbidity, high socioeconomic costs and lack of specific treatments are key factors that define the relevance of brain pathology for human health and the importance of research on neuronal protective agents. Epidemiological studies have shown beneficial effects of flavonoids on arteriosclerosis-related pathology in general and neurodegeneration in p

20. The conservative physiology of the immune system
Current immunological opinion disdains the necessity to define global interconnections between lymphocytes and regards natural autoantibodies and autoreactive T cells as intrinsically pathogenic. Immunological theories address the recognition of foreignness by independent clones of lymphocytes, not the relations among lymphocytes or between lymphocytes and t

21. The extracellular matrix in multiple sclerosis: an update
Extracellular matrix (ECM) molecules play important roles in the pathobiology of the major human central nervous system (CNS) inflammatory/demyelinating disease multiple sclerosis (MS). This mini-review highlights some recent work on CNS endothelial cell interactions with vascular basement membrane ECM as part of the cellular immune response, and roles for w

22. Imunoperoxidase nos linfomas não hodgkin diagnosticados na Universidade Estadual de Campinas
The non-Hodgkin lymphomas belong to a group of nosologic entities which present ordinary characteristics in relation to both clinical and histology, being in general divided into high and low levels of malignity. The systematization of the many subtypes of the non-Hodgkin lymphomas has been a great problem. Only in the 70 s, in the light of the immunological
