Karyotypic diversity and evolutionary trends in the neotropical catfish genus Hypostomus lacépède, 1803 (Teleostei, Siluriformes, Loricariidae)

The family Loricariidae with 813 nominal species is one of the largest fish families of the world. Hypostominae, its more complex subfamily, was recently divided into five tribes. The tribe Hypostomini is composed of a single genus, Hypostomus Lacépède, 1803, which exhibits the largest karyotypic diversity in the family Loricariidae. With the main objective of contributing to a better understanding of the relationship and the patterns of evolution among the karyotypes of Hypostomus species, cytogenetic studies were conducted in six species of the genus from Brazil and Venezuela. The results show a great chromosome variety with diploid numbers ranging from 2n=68 to 2n=76, with a clear predominance of acrocentric chromosomes. The Ag-NORs are located in terminal position in all species analyzed. Three species have single Ag-NORs (Hypostomus albopunctatus (Regan, 1908), H. prope plecostomus (Linnaeus, 1758), and H. prope paulinus (Ihering, 1905)) and three have multiple Ag-NORs (H. ancistroides (Ihering, 1911), H. prope iheringi (Regan, 1908), and H. strigaticeps (Regan, 1908)). In the process of karyotype evolution of the group, the main type of chromosome rearrangements was possibly centric fissions, which may have been facilitated by the putative tetraploid origin of Hypostomus species. The relationship between the karyotype changes and the evolution in the genus is discussed. © Anderson Luis Alves et al.

Ocorrência de pragas em algodoeiro geneticamente modificado (Bt) e convencional

The study aimed to evaluate the occurrence of pest and management of cotton genetically modified with the introduction of the bacterium Bacillus thunringiensis compared to conventional cotton in the 'Cerrado' region, installing the field experiment in 2007/2008 in Chapadão do Sul-MS. The experimental design was randomized blocks in a 2 × 3 factorial, with two managements of insecticides (with and without insecticides to control lepidopteran) and 3 modes of use of cultivars: 100% transgenic (NUOPAL), 100% non transgenic (Deltaopal) and interior area with transgenic (80% NUOPAL) with non-transgenic border (20% Deltaopal) with five replications. Evaluations were performed weekly of pest infestation, observing in 15 plants per plot the number of Alabama argillacea, Heliothis virescens and Spodoptera frugiperda. Based on these results it was concluded that: the occurrence of A. argillacea and H. virescens was lower in treated transgenic cultivar. There were no differences between transgenic and conventional farming on the occurrence of S. frugiperda.

Estudo soroepidemiológico de leishmaniose em equinos na região de Araçatuba-SP, Brasil, área endêmica para leishmaniose visceral

The aim of the present study was to perform a leishmaniasis survey in horses from Araçatuba, São Paulo, an endemic area of Brazil. Of the 466 horses tested for the presence of anti-Leishmania chagasi titers by ELISA, 68 (14.59%) were seropositive, with titers varying between 0.324 and 0.813. ELISA positive samples were also tested by immunocromatography and 19/466 (4.08%) were positive. The results of the present study indicated that equines are in contact and can attract phlebotomines, and highlight the necessity of a more accurate investigation on the role played by the horses living in endemic areas, in order to help to control the spread of the illness.

On elimination of chaotic behavior in a non-ideal portal frame structural system, using both passive and active controls

In this paper, an application is considered of both active and passive controls, to suppression of chaotic behavior of a simple portal frame, under the excitation of an unbalanced DC motor, with limited power supply (non-ideal problem). The adopted active control strategy consists of two controls: the nonlinear (feedforward) in order to keep the controlled system in a desirable orbit, and the feedback control, which may be obtained by considering state-dependent Riccati equation control to bringing the system into the desired orbit using a magneto rheological (MR) damper. To control the electric current applied in control of the MR damper the Bouc-Wen mathematical model was used to the MR damper. The passive control was obtained by means of a nonlinear sub-structure with properties of nonlinear energy sink. Simulations showed the efficiency of both the passive control (energy pumping) and active control strategies in the suppression of the chaotic behavior. © The Author(s) 2012.

The effects of combined aerobic and resistance training on heart rate variability in postmenopausal women

Model of the study: Controlled clinical trial. Objective: To verify the effects of 16 weeks of combined aerobic and resistance training on cardiac autonomic modulation in menopausal women. Methods: 17 menopausal women were divided into two groups: the training group (TG: n=11) and control group (CG: n=6). The body composition variables were estimated using dual-energy X-ray absorptiometry. The cardiac autonomic modulation was evaluated by heart rate variability using linear indexes. The training protocol consisted of 16 weeks of 50 minutes of resistance training and 30 minutes of aerobic training. Results: For the TG there was an increase in the rMSSD(ms) index (pre:17,4±3,7 and post:24,8±13,1, p<0,045), an increase in the duration of the intervals between the cardiac beats(ms) (pre:891,2±80,2 and post:974,1±71,4, p<0,003) and in the values of heart rate(bpm) (pre:68,1±6,4 and post:62,0±4,7, p<0,003), additionally for the spectral indexes in normalized units, changes for LF (pre:52,2±13,1 and post:44,5±12,4, p<0,025) and HF (pre:47,8±13,3 and post:55,5±12,4, p<0,025) were noticed, demonstrating increased parasympathetic and reduced sympathetic. There were no significant differences to CG. Conclusion: combined aerobic and resistance training promoted benefits to the autonomic modulation in menopausal women.

Comparacao das inclinacoes lateral e anteroposterior no equilibrio estatico entre jovens, adultos e idosos

INTRODUÇÃO:Com o aumento da população idosa, fica evidente a importância de compreender e explorar o processo de envelhecimento humano, o qual acarreta transformações morfológicas e funcionais.OBJETIVOS:Avaliar e comparar as inclinações anteroposterior e lateral do centro de gravidade por faixas etárias.MÉTODOS: Estudo transversal e exploratório. Fizeram parte da pesquisa 135 sujeitos, separados em faixas etárias: Grupo 1: 20-29 anos (n=26), Grupo 2: 30-39 anos (n=26), Grupo 3: 40-49 (n=25), Grupo 4: 50-59 anos (n=30) e Grupo 5: >60 anos (n=28). Esses sujeitos foram selecionados de acordo com o escore do Miniexame de Estado Mental e pela capacidade de permanecer em pé por, pelo menos, 90 segundos. As posturas foram avaliadas por meio do software de avaliação postural (SAPO). As comparações entre os valores de inclinações dados pelo SAPO foram feitas pelo teste de Mann-Whitney (comparação par-a-par), sendo aceito um valor de p<0,05 como significante.RESULTADOS:Na comparação da média da assimetria frontal entre as faixas etárias, observa-se maior lateralização com o avançar da idade, com valores significativos nos grupos 50-59 e >60 anos. Na comparação da média da assimetria sagital entre as faixas etárias, valores são significativos no grupo dos >60 anos.CONCLUSÕES:Após avaliar e comparar as assimetrias sagitais e frontais, pode-se apontar que na medida em que a idade avança, há tendência ao aumento de suas projeções anteriores e laterais comparadas ao centro de gravidade.

A classificação bibliográfica no contexto do tratamento temático da informação: um estudo com o protocolo verbal individual em bibliotecas do Instituto Federal de Educação, Ciência e Tecnologia (IF´s)

The discussions that underpin the process of bibliographic classification in documentaries systems should be designed with scientific basis and theoretical, rather than only be based on professional practice. The theoretical approaches, however, attention should also be involved in professional practice. From this, the present study seeks to demonstrate through the perception of catalogers professional, the importance of reflections on the activity of Thematic Treatment of Information, especially the bibliographic classification in order to engender the strengthening of the area and improvements in product quality and services resulting from libraries. In this context, was carried out a study in the libraries of two Federal Institutes of Education, Science and Technology (IF’s) located in two different states of southeastern Brazil. Technique was employed introspective data collection Verbal Protocol in Individual mode, having qualitative character.
