4. Histological features of the nasal mucosa in patients undergoing allogenetic hematopoietic hematopoetic stem cell transplantation with and without graft versus host disease / Caracterização histopatlologica da mucosa nasossinual em pacientes transplantados de celulas tronco hematopoieticas (TCTH) sem e com doença do enxerto contra o hospeiro (DECH)
Immunosuppression is the leading cause of recurrent sinus infections following Hematopoietic Stem Cell Transplantation (HSCT) with increased incidence of sinusitis in patients with chronic graft versus host disease (GVHD) following HSCT. Histological descriptions of the oral mucosa, lung ciliary epithelium and intestinal mucosa related to HSCT and GVHD have

5. Análise morfológica das espermátides e dos espermatozóides de Chrysomya megacephala (Fabricius) (Diptera: Calliphoridae) nos tratos reprodutores
Diptera constitutes one of the four largest orders of insects. The Oriental latrine-fly Chrysomya megacephala (Fabricius) belongs to the family Calliphoridae and is associated with medic, veterinary, sanitary and forensic issues. The aim of this research was to characterize the utrastructural aspects of the spermiogenesis and spermatozoa of the C. megacephal

6. L-Hydro treated homologous pulmonary graft vs. pulmonary homograft fresco: an experimental, comparative study / Estudo experimental comparativo do enxerto homólogo pulmonar tratado pelo processo L-Hydro com o homoenxerto pulmonar a fresco
Valve substitutes are highly important in account of their frequent use and since the success of a surgical procedure depends on their good performance. A variety of valve substitutes have been used, all presenting complications pertaining to their materials, such as thrombosis, calcification, degeneration, sterilization difficulties, cost, production comple

7. Avaliação in vitro da citotoxicidade e genotoxicidade dos polímeros de albumina magnéticos
Nanotechnology is marked by an increasing interest in the biomedical field. Nanostructured materials, such as magnetic fluids, magnetoliposomes, and magnetic polymers, composed of magnetic nanoparticles (NPMs) have been proposed for several applications: drug delivery systems, cell sorter, in vitro and in vivo diagnosis, and also for the treatment of several

8. Estudo da eletrooxidação de monóxido de carbono em RuO2(110), e visualização morfológica e atômica de fases ricas em oxigênio na oxidação de Ru(0001) através da microscopia de varredura por tunelamento / Study of the electrooxidation of carbon monoxide on RuO2(110), and morphological and atomic visualization of oxygen-rich Ru(0001) surfaces by means of Scanning Tunneling Microscopy
In the last 30 years the parallel growth of the traditional Surface Science, under UHV environment, and Electrochemistry gave rise to a new interdisciplinary field: Surface Science and Electrochemistry. Techniques from both sciences give complementary information. Thus, in tandem, they are able to elucidate many atomic, structural and electronic phenomena, o

9. Association of cyclosporine and Heteropterys aphrodisiaca (no-de-cachorro) administered to Wistar rats : testicular structure, ultrastructure and morphometry / Associação de ciclosporina e Heteropterys aphrodisiaca (no-de-cachorro) adminstrados a ratos wistar : estrutura, ultra-estrutura e morfometria testicular
Cyclosporine A (CsA) has potent immunosuppressive properties and it has markedly improved the ability of transplant patients to survive grafts and is also used in some autoimmune diseases. However, the drug has several side effects, including testicular toxicity, leading to male infertility (and temporary impotence). Stimulant and aphrodisiac properties has

10. Estrutura e ultra-estrutura das glândulas salivares de Cimex hemipterus (Fabricius, 1803) (Hemiptera: Cimicidae) / Structure and ultrastructure of the salivary glands of Cimex hemipterus (Fabricius, 1803) (Hemiptera: Cimicidae)
Cimex hemipterus is a hematophagous insect that can be an experimental host of the Trypanosoma cruzi and may play a role as vector of Chagas disease. This work analyzed the structure of the salivary glands of C. hemipterus. Adults were dissected and the salivary glands were analyzed in light microscopy and transmission electron microscopy. The secretory port

11. Microscopia eletrÃnica de varredura do endosperma do cafà (Coffea arabica L.) durante o processo de secagem / Scanning electronic microscopy in the endosperm of coffee (Coffea arabica L.) during the drying process.
After harvesting the type of processing and drying method used and the storage conditions contribute to the final drinking quality of coffee. The maintenance of the integrity of the cellular membranes, among other events, is a strong indicator that the quality of the coffee was preserved after harvesting. Therefore, this work aimed to analyze the effect of d

12. Estudo da qualidade fisiolÃgica, bioquÃmica e ultra-estrutural durante o desenvolvimento e a secagem de sementes de soja / Physiological, biochemical and ultra structural studies during the development and drying of soybean seeds
During the development and drying, several protection mechanisms act on the maintenance of the physiological quality of the seeds. Studies on desiccation tolerance allow the understanding of the events associated with the maturation of orthodox seeds, such as soybean. Among the mechanism involved on desiccation tolerance, the activity of heat-resistant prote
