    Timber management directly influences the population dynamics of tree species, like Copaifera spp. (copaíba), which provide oil-resin with ecological and economic importance. The aim of this study was to evaluate the structure and population dynamics of Copaifera in unmanaged and managed stands by reduced-impact logging (RIL) in eastern Amazon in Pará state, Brazil. Based on a stem map of the study area, 40 Copaifera trees were randomly selected, where an equal number of trees were selected in managed and unmanaged stands. A transect of 10 × 100 m was centered at each tree (50 m each side) to assess Copaifera regeneration. Transects were subdivided into ten plots, of which six were systematically chosen to assess the height, diameter and number of Copaifera seedlings and saplings. The field assessment occurred in 2011 and 2013. To estimate the amount of sunlight transmitted to the forest floor, we computed canopy cover from airborne LiDAR data. According to the results, the abundance of Copaifera seedlings/saplings was higher in managed than unmanaged stands. About 5% of Copaifera regeneration was found between 45–50 m from the Copaifera tree while ~73% of regeneration was concentrated within a 10 m radius of the Copaifera tree. We verified that the diameter distribution of Copaifera regeneration was not a negative exponential distribution, as is typical of most tree species in natural forest. Rather, the Copaifera regeneration had a spatially aggregated distribution. In this short-term analysis, the impact of timber management is not negatively affecting the population structure or dynamics of Copaifera regeneration

    Estudo de caso que objetivou identificar os Diagnósticos de Enfermagem (DE) conforme taxonomia II da Nursing American Nursing Association (NANDA), em idoso vítima de queimaduras de 2° e 3° graus e elaborar as intervenções de Enfermagem. Foram identificados oito DE, sendo cinco com presença de características definidoras e fatores relacionados (atuais) e três de risco. Elaborou-se propostas de intervenção iniciando pelas necessidades relacionadas aos sistemas vitais, fisiológicos, base da hierarquia das necessidades humanas básicas. Ao final, observou-se a importância da aplicabilidade do processo de enfermagem na implementação do cuidado e a necessidade do mesmo no exercício do fazer cotidiano.<br>Estúdio de caso cuyo objetivo fué identificar los Diagnósticos de Enfermería (DE) según la taxonomia II de North Ameircan Nursing Diagnosis Association (NANDA), de lo anciano com quemadura de 2° e 3° grado. Fueron identificados ocho DE de los más, cinco con presencia de características definidoras y factores relacionados (reales), y três de riesgos. Posteriomente, fueron elaboradas las porpuestas de intervención comenzado por la aplicabilidad del proceso de enfermería em la implementación del cuidado y la necessidad del mismo en el ejercício del hacer diário de enfermería.<br>This case study aimed at identifying the Nursing Diagnosis (ND) in agreement with the taxonomy II of the North-American Nursing Diagnosis Association (NANDA) of a patient victim of burning of 2nd e 3th degrees and to elaborate the nursing interventions. Eight ND were identified being five with the presence of defining characteristics and related factors (real), and three of risk. Intervention proposal was elaborated starting by the needs related to the vital and physiologic signs, the base of human basic needs hierarchy. Finally, it was observed the relevance of nursing process applicability in the implementation of care and its need in daily nursinga activitiies

    Functional organization of the yeast proteome by systematic analysis of protein complexes.

    Most cellular processes are carried out by multiprotein complexes. The identification and analysis of their components provides insight into how the ensemble of expressed proteins (proteome) is organized into functional units. We used tandem-affinity purification (TAP) and mass spectrometry in a large-scale approach to characterize multiprotein complexes in Saccharomyces cerevisiae. We processed 1,739 genes, including 1,143 human orthologues of relevance to human biology, and purified 589 protein assemblies. Bioinformatic analysis of these assemblies defined 232 distinct multiprotein complexes and proposed new cellular roles for 344 proteins, including 231 proteins with no previous functional annotation. Comparison of yeast and human complexes showed that conservation across species extends from single proteins to their molecular environment. Our analysis provides an outline of the eukaryotic proteome as a network of protein complexes at a level of organization beyond binary interactions. This higher-order map contains fundamental biological information and offers the context for a more reasoned and informed approach to drug discovery
