Ant species diversity in ciliary forest and gallery forest areas in central Brazil

Advances in Entomology 2014年第1期2卷 24-32页

作者： Joao Augusto Vieira de Oliveira Daiane Martins da Silva Flávia Assumpcao santana Unidade Universitária Universidade Estadual de GoiásQuirinópolisBrazil

Ants make up an important group of insects of the Cerrado in terms of biomass, number of individuals, and ecological impact. The main goals of this study were to quantify the species richness and species diversity of the family Formicidae in two riparian Cerrado physiognomies: Ciliary Forest and Gallery Forest, and to evaluate the effectiveness of two collection techniques for these organisms. The study was conducted during the dry season, comprising the months of May to October 2012, in the municipality of Quirinópolis, Goiás State, Brazil. Samples were made using two capture techniques: sardine baits and pitfall traps. Manual collection was employed to extend the range of faunistic composition of the ants. We collected 24 species of ants in the Gallery Forest and 23 in the Ciliary Forest. The genus Megalomyrmex was the most representative, being present in 49.46% of the samples, and secondly the genus Pheidole, with 15.36% of the total individuals captured. From a total of 10,917 individuals, 9140 were captured using the bait technique, 1738 with traps, and 39 individuals through manual collection. Similar results were found in the Cerrado of Paineiras, with 45 ant species distributed in 16 genera belonging to 5 subfamilies.

Immunological Intolerance and Tolerance by Antigenic Co-Stimulation

引用

Open Journal of Immunology 2017年第4期7卷 59-84页

作者： Alexandre Paulo Machado Gabriel de Paula Albuquerque Letícia Souza santana Olga Fischman Gompertz Department of Basic Health Sciences Federal University of Mato Grosso Cuiabá Brazil Medical Faculty Federal University of Mato Grosso Cuiabá Brazil Cell Biology Division Department of Microbiology Immunology and Parasitology Federal University of S&atilde o Paulo S&atilde o Paulo Brazil

The plasticity and dynamism in the immune responses to both self and environmental stimulation promote the maintenance and adaptation of a system that tends to harmoniously survive and evolve. Fluctuating antigenic forces coexist within the immune system and oscillate between order and chaos to the equilibrium. Thus, when mounting a response to internal or environmental antigens, the main host responses can be divided into two immunological categories. The first, a well-adapted mechanism of complex multi-cellular organisms classically known as tolerance, promotes persistent immunological responses. In the second, opposite way, the modulation of inflammatory immune responses occurs, which we call “intolerance”. Tolerance and intolerance can be mediated by humoral molecules, such as inflammatory compounds, complement, and antibodies, and by different cell types, such as sentinel cells, antigen-presenting cells, and cells that orchestrate the immune response. Tolerogenesis is important in vertebrates because it predisposes species to adapt to self and environmental negative-selective forces. This process depends, in large part, on antigenic co-stimulation (AgCS), which operates as a multi-integrated network formed by all immune and non-immune cells of the body that establishes tolerant immunoregulatory interactions from cells to cells and from cells to the environment. Antigenic distribution, quantity, nature, route of administration, and antigenic convergence on co-stimulatory pathways, and concurrent infections, and the presence of microorganisms (commensals and pathogens) in more than one site are important factors for activating AgCS. To conclude, the AgCS route is a natural immune response generated by heterogeneous APC profile with centralized regulation that promote the counterbalance between intolerant e tolerant status, which can have several applications in the medical and biological fields.

Background： Leptin has a strong relation to important traits in animal production, such as carcass composition,feed intake, and reproduction. It is mainly produced by adipose cells and acts predominantly in the *** this study, circulating leptin and its gene expression in muscle were evaluated in two groups of young Nellore bulls with divergent feed efficiency. Individual dry matter intake（DMI） and average daily gain（ADG） of 98 Nellore bulls were evaluated in feedlot for 70 d to determinate the residual feed intake（RFI） and select 20 animals for the high feed efficient（LRFI） and 20 for the low feed efficient（HRFI） groups. Blood samples were collected on d 56 and at slaughter（80 d） to determine circulating plasma leptin. Samples of Longissimus dorsi were taken at slaughter for leptin gene expression ***： DMI and RFI were different between groups and LRFI animals showed less back fat and rump fat thickness,as well as less pelvic and kidney fat weight. Circulating leptin increased over time in all animals. Plasma leptin was greater in LRFI on 56 d and at slaughter（P = 0.0049）. Gene expression of leptin were greater in LRFI animals（P = 0.0022） in accordance with the plasma levels. The animals of the LRFI group were leaner, ate less, and had more circulating leptin and its gene ***： These findings demonstrated that leptin plays its physiological role in young Nellore bulls, probably controlling food intake because feed efficient animals have more leptin and lower residual feed intake.
