25. Consolidação do processo de informatização em Sistemas de Bibliotecas Universitárias na África do Sul, Brasil e Moçambique
The thesis, based on a comparative study of university libraries in developing countries (Brazil, South Africa, and Mozambique) discusses the computerization process of these libraries, and by using an integrated approach includes, besides the technological aspects, those aspects related with process management, work organization and workers qualification, a

26. Schistosomal granuloma as a system adaptive complex. Application of fractal dimension in characterization of their geometric properties. / Granuloma esquistossomótico como um sistema adaptativo complexo. Aplicação da dimensão fractal na caracterização de suas propriedades geométricas.
Schistosomal granuloma AS A COMPLEX ADAPTIVE SYSTEM: APPLICATION OF FRACTAL DIMENSION IN THE CHARACTERIZATION OF PROPERTIES GEOMETRIC. Waldemiro de Souza Romagna. [Introduction]. The schistosomal granuloma is a compact, organized collection of migrating cells, which along with cells of the affected organ, arrange themselves in the midst of extracellular matr

27. Central polynomials for graded algebras / Polinomios centrais para algebras graduadas
In this thesis we study graded central polynomials and central polynomials with involution for some important algebras in the theory of algebras with polynomial identities, over infinite fields. Namely we describe the Z2-graded central polynomials for the algebras M2(K) (the 2 x 2 matrices over the field K), Ml,1(5), where 5 is an arbitrary supercommutative

28. Proliferação, apoptose e morfometria do útero e da placenta de ratas hipertireóideas na gestação e no pós-parto associadas ao desenvolvimento fetal
In two different experiments, the hyperthyroidism effect was evaluated on the proliferation rate, apoptosis and morphometry of uterus and placenta during gestation, fetal development and after birth. In the first experiment, 36 sexually mature female Wistar rats were distributed in two groups of 18 animals: hyperthyroid and euthyroid (control). The female ra

29. Finasteride effects on epithelium-stroma interaction in the different rat prostatic lobes / Efeito da finasterida sobre a interação epitelio-estroma nos diferentes lobos da prostata de rato
Prostate cancer cells are generally dependent on androgen stimulation mediated by the androgen receptor (AR) for growth and survival. Therefore, hormonal manipulation, such as castration and/or the use of AR antagonists, results in a regression of the cancer. However, these treatments very rarely lead to the cure of advanced disease and cancer eventually bec

30. Analise da influencia do diabetes tipo I induzido na progressão da doença periodontal experimental em ratos / Analysis of the influence of diabetes type I induced in the progression of experimental periodontal disease in rats
The periodontal disease is characterized as a group of lesions that affect the tissues which surround and support the teeth in their correct places. The bacterial plaque is the major ethiological agent, and most evidences suggest the periodontal disease is not simply associated with oral cavity colonization by pathogenic microorganisms, but to host susceptib

31. The involution of the mammary gland in Holstein cows: clinical evaluation of the udder and physicochemical, cellular and microbiological characteristics of the lacteal secretion in the dry period / Processo de secagem da glândula mamária de bovinos da raça holandesa: avaliação física da involução da mama e das características físico-químicas, celulares e microbiológicas da secreção láctea durante o período seco
Com o objetivo de avaliar o processo de secagem da glândula mamária de vacas da raça Holandesa foram examinadas 44 mamas na fase final da lactação, durante a evolução do processo de secagem (dia da última ordenha; 1º, 3º, 5º, 7º, 10º, 15º, 30º e 45º dia do período seco), assim como no retorno à lactação. Antes da colheita das amostras, a

32. Thymus involution in alloxan diabetes: analysis of mast cells
We previously reported that alloxan-induced diabetes results in reduction in the number and reactivity of mast cells at different body sites. In this study, the influence of diabetes on thymic mast cells was investigated. Thymuses from diabetic rats showed marked alterations including shrinkage, thymocyte depletion, and increase in the extracellular matrix n

33. Expressão espaço-temporal de marcadores de poliferação e morte celular na sinfise pubica de camundongo durante a prenhez, parto e pos-parto
Marked changes in mice pubic symphysis occurs by the end of pregnancy. Recently, we demonstrated that these changes in the pubic symphysis during the period under study are directly associated with extracellular matrix components remodeling mainly collagen, elastic fibers system, proteoglycans and glycosaminoglycans. Tissue remodeling involves a dynamic bala

34. Reposição hormonal na prostata ventral de ratos castrados : recuperação glandular, reorganização estremal e atividade de metaloproteinases de matriz
The ventral prostate (VP) and the seminal vesic1e (SV) are both androgen dependents, in which undergoe atrophy and regrowth processes afier androgen deprivation and reposition. In both events, it was observed alterations in the epithelium as well as in the stromal compartiments. The aspects related to the prostate epithelium induced by testosterone replaceme

35. Expressão do Reck, um inibidor de metaloproteinases de matriz, no desenvolvimento pos-natal e na regressão prostatica pos-castração / Expression of Reck, an inhibitor of matrix metalloproteinases, in the prostatic postnatal development and involution after castration
A próstata tem merecido crescente atenção devido à maior incidência de câncer prostático e outras afecções do órgão, que resultam do aumento na longevidade dos indivíduos do sexo masculino em todo o mundo. Além disto, o desenvolvimento e crescimento prostático normal apresenta regulação androgênica e está sujeito a uma série de disruptores

36. Estudo bioquimico e histoquimico do acido hialuronico no tecido interpublico de camundongo durante a prenhez, parto e pos-parto
The interpubic tissue in mice is known to rapidly adapt itself to the ali new demands imposed during pregnancy, partum and post-partum. The development of an interpubic ligament may be explained, in part, due to the modifications observed in the hydration of this tissue, as well as, the presence of hyaluronan (HA). The present study focuses on the presence o
