Human tonsil germinal center (GC) B cells rapidly undergo apoptosis in culture. Annexin-V binding shows an early event in this process. In the present study, this method has been used to label apoptotic GC B cells and to analyze additional surface molecules. The expression of all of the molecules studied was reduced in apoptotic (annexin-V+) GC B cells, and the reduction was more marked for CD11a, CD21, CD22, CD49d, and CD54, molecules that participate in survival interaction for GC B cells. The analysis ...

Animal tuberculosis (TB) is endemic in wild boar (Sus scrofa), red deer (Cervus elaphus), fallow deer (Dama dama) and cattle in south and central Spain. In order to clarify the processes that operate in the medium and long-term, we studied TB at the wildlife-livestock interface in Doñana National Park for 14 years (2006-2018) in relation to host density, stochastic factors (rainfall) and environmental features (e.g., aggregation points such as waterholes). Wild boar showed the highest prevalence of TB ( ...

Toxoplasma gondii is an obligate intracellular protozoan which infects warm-blooded vertebrates, including humans, worldwide. In the present study, the epidemiology of T. gondii was studied in the wild ungulate host community (wild boar, red deer, and fallow deer) of Doñana National Park (DNP, south-western Spain) for 13 years (2005-2018). We assessed several variables which potentially operate in the medium and long-term (environmental features, population, and stochastic factors). Overall, the wild ...

The technical viability of the BRISA process (Biolixiviación Rápida Indirecta con Separación de Acciones: Fast Indirect Bioleaching with Actions Separation) for the copper recovery from chalcopyrite concentrates has been proved. Two copper concentrates (with a copper content of 8.9 and 9.9 wt.%) with chalcopyrite as the dominant copper mineral have been leached with ferric sulphate at 12 g/L of ferric iron and pH 1.25 in agitated reactors using silver as a catalyst. Effects of temperature, amount ...

Nowadays a number of diverse biochemical markers have been identified in patients with heart failure (HF) that could indicate the severity of the patients' illness. Among them, probably the most useful is brain natriuretic peptide (BNP) because it is easily obtained and because of its diagnostic and prognostic information. Our objective was to assess the association between BNP and other different associated variables previously known to be related to the evolution of HF, as well as its utility to ...

The selection of the operating conditions of a continuous silver catalyzed IBES (Indirect Bioleaching with Effects Separation) process for a chalcopyrite–sphalerite concentrate from Rio Tinto is presented. The data generated from the batch tests have been used to estimate the operating parameters for the continuous system. In order to obtain metal extractions of 94% Zn and 95% Cu, two ferric sulphate leaching stages are necessary: a primary leaching at 70°C with a mean residence time of 8 h divided ...

The specific influence of malnutrition on the pathophysiological changes induced by chronic alcoholism is controversial; most studies are inconclusive because they have been made in chronic alcoholics that develop malnutrition as a complication of alcoholism. However, in vast human groups, alcoholism evolves in individuals that belong to a chronically undernourished population. In an attempt to simulate real-life conditions of malnutrition-alcoholism in humans, we studied in rats: (1) the effects ...

The specific influence of malnutrition on the cellular damage induced by alcoholism has been poorly defined; therefore, the possible degree of improvement that could be obtained after the institution of proper nutrition and after alcohol withdrawal remains unclear. We studied both conditions in several combinations, either after chronic alcoholism, chronic malnutrition or both, and after reversal of each condition or of both.Using experimental models of alcoholism and malnutrition, we studied the ...

Research into Roman provincial organization is inseparable from the study of the evolution of provincial social structures. The authors incorporate this perspective into the landscape archaeological program, "Social Structure and Territory in Roman Iberia." The results of this program in two areas of the Iberian peninsula where mining was practiced intensively during the Roman period, Carthago Noua in the southeast and the peninsular northwest, demonstrate that the Romans took various approaches ...

Tumor immune escape is associated with the loss of tumor HLA class I (HLA-I) expression commonly found in malignant cells. Accumulating evidence suggests that the efficacy of immunotherapy depends on the expression levels of HLA class I molecules on tumors cells. It also depends on the molecular mechanism underlying the loss of HLA expression, which could be reversible/"soft" or irreversible/"hard" due to genetic alterations in HLA, β2-microglobulin or IFN genes. Immune selection of HLA-I negative ...

In this paper the biological ferrous iron oxidation in flooded packed bed reactors is studied. Bacterial oxidation of ferrous iron is a potential industrial process for the treatment of acid mine drainage and in the regeneration of ferric iron as a leaching agent in hydrometallurgical processes. The aim of this work is the development of a reactor capable of attaining the oxidation rates demanded by industrial processes, which are higher than those shown in the literature. The bioreactor consists ...

The indirect bioleaching with effect separation process has been applied to a chalcopyrite–sphalerite concentrate from Rio Tinto. In this paper the biooxidation of the ferrous iron generated in the chemical stage (ferric sulphate leaching) and the recovery of the silver used as a catalyst have been studied. The ferrous iron in leaching liquors can be effectively biooxidized both in static batch and packed-bed reactors. The regenerated ferric iron can be recycled to the chemical stage of the process. ...

The Spanish Civil War (1936–1939) and posterior dictatorship (until 1970s) stands as one of the major conflicts in the recent history of Spain. It led to nearly two hundred thousand men and women executed or murdered extra-judicially or after dubious legal procedures. Nowadays, most of them remain unidentified or even buried in irretraceable mass graves across Spain. Here, we present the genetic identification of human remains found in 26 mass graves located in Northern Spain. A total of 252 post- ...
