Assembly mechanisms of dung beetles in temperate forests and grazing pastures

The role of deterministic and stochastic mechanisms in community assembly is a key question in ecology, but little is known about their relative contribution in dung beetle assemblages. Moreover, in human modified landscapes these mechanisms are crucial to understand how biodiversity can be maintained in productive agroecosystems. We explored the assembly mechanisms driving dung...

Exploiting the overhearing capabilities of transmitting nodes to increase the energy efficiency in dense networks

The 1000-fold capacity increase envisioned by dense 5G networks results also in a tremendous increase in the energy consumption of the whole network. Utilizing relays in combination with physical-layer network coding (PNC) has been proposed as an energy-efficient solution to this problem by creating several short-distance low-power transmissions and by reducing the transmission...

Variación temporal de visitantes florales en dos especies simpátricas de Salvia con floración simultánea y síndrome de polinización contrastante

Pollination systems in Salvia are specialized, and species have been mainly classified as melittophilic (visited by bees) or ornithophilic, visited by birds. Both systems often occur in sympatry and species bloom simultaneously. This scenario allowed us to evaluate the correspondence between contrasting floral morphologies and functional groups of flower visitors, and their role...

Promiscuous Recognition of a Trypanosoma cruzi CD8+ T Cell Epitope among HLA-A2, HLA-A24 and HLA-A1 Supertypes in Chagasic Patients

Background TcTLE is a nonamer peptide from Trypanosoma cruzi KMP-11 protein that is conserved among different parasite strains and that is presented by different HLA-A molecules from the A2 supertype. Because peptides presented by several major histocompatibility complex (MHC) supertypes are potential targets for immunotherapy, the aim of this study was to determine whether MHC...

Complexes of D-type cyclins with CDKs during maize germination

The importance of cell proliferation in plant growth and development has been well documented. The majority of studies on basic cell cycle mechanisms in plants have been at the level of gene expression and much less knowledge has accumulated in terms of protein interactions and activation. Two key proteins, cyclins and cyclin-dependent kinases (CDKs) are fundamental for cell...

Low Frequency of Circulating CD8+ T Stem Cell Memory Cells in Chronic Chagasic Patients with Severe Forms of the Disease

Background CD8+ T cells have been shown to play a crucial role in Trypanosoma cruzi infection. Memory CD8+ T cells can be categorised based on their distinct differentiation stages and functional activities as follows: stem cell memory (TSCM), central memory (TCM), transitional memory (TTM), effector memory (TEM) and terminal effector (TTE) cells. Currently, the immune mechanisms...

Células dendríticas y linfocitos T reguladores naturales en pacientes con enfermedad crónica de Chagas

Given the chronicity and persistence of the parasite Trypanosoma cruzi in the Chagas disease victims, the homeostatic control of immune response to prevent tissue damage and limit the duration of the inflammatory process involves cells with regulatory potential as dendritic cells (DC) and regulatory T cells. For this reason, the objective of this study is to evaluate the...
