Química Analítica: Una Oportunidad para la Inclusión de Aspectos Sociales y Culturales en Ingeniería Química

The purpose of this article is to analyze and identify the type of social and cultural aspects that can be included during the teaching of a technical course such as Analytical Chemistry. To this end, a comparative analysis of the Analytical Chemistry curriculum for the Chemical Engineering major in five universities, four from Argentina and one from Spain, was done. Interviews...

Yearly fluctuations of flower landscape in a Mediterranean scrubland: Consequences for floral resource availability

Species flower production and flowering phenology vary from year to year due to extrinsic factors. Inter-annual variability in flowering patterns may have important consequences for attractiveness to pollinators, and ultimately, plant reproductive output. To understand the consequences of flowering pattern variability, a community approach is necessary because pollinator flower...

CSF1R Protein Expression in Reactive Lymphoid Tissues and Lymphoma: Its Relevance in Classical Hodgkin Lymphoma

Tumour-associated macrophages (TAMs) have been associated with survival in classic Hodgkin lymphoma (cHL) and other lymphoma types. The maturation and differentiation of tissue macrophages depends upon interactions between colony-stimulating factor 1 receptor (CSF1R) and its ligands. There remains, however, a lack of consistent information on CSF1R expression in TAMs. A new...

Specialization in Plant-Hummingbird Networks Is Associated with Species Richness, Contemporary Precipitation and Quaternary Climate-Change Velocity

Large-scale geographical patterns of biotic specialization and the underlying drivers are poorly understood, but it is widely believed that climate plays an important role in determining specialization. As climate-driven range dynamics should diminish local adaptations and favor generalization, one hypothesis is that contemporary biotic specialization is determined by the degree...

Mispair Extension Fidelity of Human Immunodeficiency Virus Type 1 Reverse Transcriptases with Amino Acid Substitutions Affecting Tyr115

The role of Tyr115 of human immunodeficiency virus type 1 reverse transcriptase (HIV-1 RT) in the mispair extension fidelity of DNA dependent DNA synthesis was analysed by using a series of 15 mutant enzymes with substitutions at Tyr115. Their kinetic parameters for elongation using homopolymeric RNA-DNA and heteropolymeric DNA-DNA complexes showed major effects of the amino acid...
