TL;DR: A linked organization for the 5S rRNA and H3 histone multigene families investigated in R. brasiliensis is indicated, reinforcing previous data concerning the association of both genes in some insect groups and contributing to understanding the organization/evolution of multigenes families in the insect genomes.
Abstract: Supernumerary B chromosomes occur in addition to standard karyotype and have been described in about 15% of eukaryotes, being the repetitive DNAs the major component of these chromosomes, including in some cases the presence of multigene families. To advance in the understanding of chromosomal organization of multigene families and B chromosome structure and evolution, the distribution of rRNA and H3 histone genes were analyzed in the standard karyotype and B chromosome of three populations of the grasshopper Rhammatocerus brasiliensis. The location of major rDNA was coincident with the previous analysis for this species. On the other hand, the 5S rDNA mapped in almost all chromosomes of the standard complement (except in the pair 11) and in the B chromosome, showing a distinct result from other populations previously analyzed. Besides the spreading of 5S rDNA in the genome of R. brasiliensis it was also observed multiple sites for H3 histone genes, being located in the same chromosomal regions of 5S rDNAs, including the presence of the H3 gene in the B chromosome. Due to the intense spreading of 5S rRNA and H3 histone genes in the genome of R. brasiliensis, their chromosomal distribution was not informative in the clarification of the origin of B elements. Our results indicate a linked organization for the 5S rRNA and H3 histone multigene families investigated in R. brasiliensis, reinforcing previous data concerning the association of both genes in some insect groups. The present findings contribute to understanding the organization/evolution of multigene families in the insect genomes.

TL;DR: The results suggest that the performance of the push up exercise on an unstable surface may be more favorable to produce higher levels of trapezius activation and lower levels of serratus anterior activation, if the goal of the exercise program is the strengthening of the SA muscle.

TL;DR: There is a need for more incentives by the institution and through policies, so as to permit nurses a greater autonomy in their practice, and the absence of forms in most hospitalization units is identified.
Abstract: The objective of this study is to analyze the knowledge that nurses from a large hospital in Recife, Pernambuco, have about Nursing Care Systematization (NCS). This is a descriptive, exploratory, quantitative study. The study population consisted of 107 clinical nurses, with a sample of 73 (68%). Data collection was performed in June 2008, using a semi-structured questionnaire that was filled out by the subjects. We found that 50 (69%) nurses had no knowledge about NCS, especially about nursing diagnoses. We identified the absence of forms in most hospitalization units. The nurses gave several justifications for their not working with NCS, including work overload and the scarcity of forms. We concluded that there is a need for more incentives by the institution and through policies, so as to permit nurses a greater autonomy in their practice.
