Nickel salts of Keggin heteropolytungstates with the general formula NixAyW12−yO39or40 (A = Si/P) were synthesized and studied as bulk catalytic materials or supported ones by deposition on modified and functionalized ...

Evidence suggesting that statins may contribute to renoprotection has been provided in experimental 28 and clinical studies. Statins restore endothelial nitric oxide (NO) levels by mechanisms including up-reg- 29 ulation...

We study the effect of decoherence upon the neutrino spectra produced in microquasar jets. In order to analyse the precession of the polarization vector of neutrinos we have calculated its time evolution by solving the c...

It is estimated that there are between 2.2 and 3.8 million species of fungi, but only 3 to 8% are known. The order Agaricales in Argentina is not well known in certain areas and plant communities, as the Reserva Ecológi...

Nitrogen availability in Buglossoides arvensis mother plants influences seed dormancy level. Abscisic acid (ABA) levels chiefly determine primary dormancy during embryo maturation and its maintenance depends on ABA/gibbe...

Strongly proteolytic starters seem to improve the growth of non-starter lactobacilli during cheese ripening, but no information is available on the impact of the non-microbial proteases usually active in cheese on their ...

This article examines higher education and knowledge as Global Public Goods from a Global South perspective, arguing that their roles in development, inclusion, and innovation cannot be fully understood through dominant ...

The probiotic Gram-positive bacterium Lactobacillus casei BL23 is naturally confronted with salt- stress habitats. It has been previously reported that growth in high-salt medium, containing 0.8 M NaCl, leads to modifica...

In order to clarify the physiological role of ghrelin in gestation, we evaluated the effects of administration of exogenous ghrelin (2 or 4 nmol/animal per day) or its antagonist (6 nmol/animal per day of (D-Lys3)GHRP6) ...

We performed a systematic approach using statistical tools to understand the effect of the water chemistry on removal of microorganisms using ultrafiltration. We applied a four-factor at two-level factorial design with c...

Chronic lymphocytic leukemia (CLL) is characterized by the progressive accumulation of clonal B lymphocytes. Proliferation occurs in lymphoid tissues upon interaction of leukemic cells with a supportive microenvironment....

The relationship between the immune system and angiogenesis has been described in several contexts, both in physiological and pathological conditions, as pregnancy and cancer. In fact, different types of immune cells, su...

During postnatal development, the central nervous system (CNS) is highly sensitive to effects of drugs, stressors and environment. In this study, we evaluated the effect of acute cold stress on g-aminobutyric acid (GABA)...

Imidazolinone resistance found in a wild sunflower (Helianthus annuus L.) population was successfully transferred to a cultivated inbred line developing ‘Imisun’ sunflowers. Genetic regulation of this trait has been ...

A exposição da miséria nos espaços públicos, fruto do aumento das desigualdades sociais no mundo capitalista e globalizado, é um fenômeno urbano que se amplia nas grandes metrópoles brasileiras. As atividades des...

Abstract Expressionism can be seen as a valid expression of the crisis of ‘Modern Man’ and, as a result, it assumed a central role in the cultural debate of its time. Within this crisis can be situated a new form o...

Querido Guillermo, Você sabe que essas conferências magistrais me produzem pânico. Então, para quebrar o protocolo, quer dizer, os usos e costumes da academia, decidi que seria melhor lhe escrever para recordarmos a ...

Sensitization to psychostimulants is strongly influenced by the environmental context in which the drug is administered and little is known about the molecular mechanisms that regulate this process. Chronic treatment wit...

Early ethanol exposure alters neonatal breathing plasticity. Respiratory EtOH's effects are attributed to central respiratory network disruptions, particularly in the medullary serotonin (5HT) system. In this study we ev...

Early ethanol exposure affects respiratory neuroplasticity; a risk factor associated with the Sudden Infant Death Syndrome. High and chronic ethanol doses exert long-lasting effects upon respiratory rates, apneic episode...

Brain expression of the enzyme P450-aromatase has been studied extensively. Subsequent to the aromatisation hypothesis having established brain aromatase as a key factor to convert gonadal testosterone to oestradiol, sev...

The aim of the present study was to evaluate whether the activation of Cdk5, a protein that has been suggested to participate in higher cognitive functions, is required for the onset of a sensitized anxiety-related behav...

The decomposition of Erythrina crista-galli L. (Leguminosa) leaf litter and its colonization by invertebrates were studied in a secondary channel of the Middle Paran´a River. This species is native to and very abundant ...

In this study, we describe and illustrate Piriqueta crenata, a new species from the Chapada Diamantina region, Bahia,Brazil. It is similar to and was initially identified as P. flammea from which it can be distinguished ...
