1. Aplicabilidade e validação do Geant4 para fótons e elétrons em radioterapia / GEANT4 applicability and validation to Photons and Electrons in Radiotherapy
Due to the increasing use of ionizing radiation in medical applications, in recent decades, the simulation codes for radiation interacting with matter, based on Monte Carlo Method, have been constantly adapted to applications in medical physics. TheMonte Carlo method is a statisticalmethod of numerical simulation of problems using essentially a sequence of r

2. Absenteísmo e sua relação com o ambiente de trabalho e sua interferência no cuidado de Enfermagem / Absenteeism and its relation to the workplace and its influence on nursing care
This research aimed at studying absenteeism, its relationship to the workplace and its influence on nursing care. It is a descriptive, exploratory study of qualitative approach based on the Systems Theory, which considers its integral parts as being independent and interacting, interrelated, and influencing each other. Data collection occurred between June a

3. Study of the effect of pulsed electric field on bone healing in rats tibia / Estudo do efeito de campo elétrico pulsado no reparo ósseo em tíbia de ratos
The concept that electrical stimulation promotes the repair of fractures has a long history, dated of 1812. The mechanism for which electrical stimulation promotes osteogenesis is still subject of scientific speculation, however that method non-pharmacological, used in the present work has already showed positive effects in the promotion and incentive of ost

4. SANDY BEACH MORPHODYNAMICS AND MACROBENTHIC COMMUNITIES IN TEMPERATE, SUBTROPICAL AND TROPICAL REGIONS - A MACROECOLOGICAL APPROACH
A comprehensive study involving 52 microtidal beaches spanning from reflective to dissipative states and located in tropical, subtropical and temperate regions in the Atlantic, Pacific and Indian oceans was carried out to unravel the relative roles of latitude and beach morphodynamics in determining beach macrobenthic species richness, abundance, biomass and

5. Limnologia comparativa de três lagoas neotropicais da Bacia do Magdalena Médio Santandereano (Colômbia), com ênfase no estudo da diversidade da comunidadezooplanctônica e sua relação com a dinâmica hidrológica do sistema regional.
Few studies have been developed regarding zooplankton diversity in Neotropical Region, particularly in Colombia. Regarding the diversity in the Tropical region still there are a great controversy, despite the relevance of this community as indicator of climate or hydrological, physical and chemical changes. A limnological study was performed during the perio

6. Survival of Escherichia coli and Salmonella spp. in estuarine environments.
Survival of Escherichia coli and Salmonella spp. in estuarine waters was compared over a variety of seasonal temperatures during in situ exposure in diffusion chambers. Sublethal stress was measured by both selective-versus-resuscitative enumeration procedures and an electrochemical detection method. E. coli and Salmonella spp. test suspensions, prepared to

7. Imaging of the diffusion of single band 3 molecules on normal and mutant erythrocytes
Membrane-spanning proteins may interact with a variety of other integral and peripheral membrane proteins via a diversity of protein-protein interactions. Not surprisingly, defects or mutations in any one of these interacting components can impact the physical and biological properties on the entire complex. Here we use quantum dots to image the diffusion of

8. The source of NMR-detected motional anisotropy of water in blood vessel walls.
2H Double quantum-filtered (DQF) NMR spectroscopy of deuterated water is sensitive to the presence of order in biological systems. This is because the only nuclei that are detected are those with residual quadrupolar interactions due to their anisotropic motion. In the present study, samples of aorta, coronary and carotid arteries, and vena cava were studied

9. In Vitro and In Vivo Interactions of DNA Ligase IV with a Subunit of the Condensin Complex
Several findings have revealed a likely role for DNA ligase IV, and interacting protein XRCC4, in the final steps of mammalian DNA double-strand break repair. Recent evidence suggests that the human DNA ligase IV protein plays a critical role in the maintenance of genomic stability. To identify protein–protein interactions that may shed further light on th

10. Direct Physical and Functional Interaction of the NuA4 Complex Components Yaf9p and Swc4p
Saccharomyces cerevisiae Yaf9p and the mammalian leukemia-associated protein ENL share a high degree of similarity. To investigate the biological function of Yaf9p, this protein was used to search for interacting proteins in a two-hybrid system. Here, we demonstrate that Yaf9p binds directly to Swc4p, the yeast homolog of the mammalian DNA-methyltransferase-

11. Characterization of Wise Protein and Its Molecular Mechanism to Interact with both Wnt and BMP Signals*
Cross-talk of BMP and Wnt signaling pathways has been implicated in many aspects of biological events during embryogenesis and in adulthood. A secreted protein Wise and its orthologs (Sostdc1, USAG-1, and Ectodin) have been shown to modulate Wnt signaling and also inhibit BMP signals. Modulation of Wnt signaling activity by Wise is brought about by an intera

12. Members of the AP-1 Family, c-Jun and c-Fos, Functionally Interact with JC Virus Early Regulatory Protein Large T Antigen
The activating protein 1 (AP-1) family of regulatory proteins is characterized as immediate-early inducible transcription factors which were shown to be activated by a variety of stress-related stimuli and to be involved in numerous biological processes, including cellular and viral gene expression, cell proliferation, differentiation, and tumorigenesis. We
