Analysis of the economic viability from an integrated system of rice and beef cattle in the Pampa Biome of Rio Grande do Sul.

The environmental conditions of the Pampa Biome are favorable to the degradation of soil, especially when grain crops are introduced in this region, traditionally exploited with beef cattle systems

Raising Brangus steers on natural pasture developed after irrigated rice crop in the Pampa biome of Rio Grande do Sul state, Brazil.

The traditional systems of exploitation with beef cattle in the Pampa biome of Rio Grande do Sul presents historically low rates of productivity and profitability due, mainly, to the inadequate management of natural pastures

Desempenho de novilhos Brangus em pastagem natural sobre solo hidromórfico em Bagé/RS, no período fevereiro de 2009 a abril de 2010.

O objetivo do presente trabalho foi verificar o efeito da irrigação por inundação em período de estresse hídrico sobre o ganho de peso de novilhos na Estação Experimental da Embrapa Pecuária Sul.bitstream/item/88356/1/CoT842013.pd

Molecular Data Reveal Complex Hybridization and a Cryptic Species of Neotropical Wild Cat

SummaryHybridization among animal species has recently become more recognized as an important phenomenon, especially in the context of recent radiations [1–9]. Here we show that complex hybridization has led to contrasting patterns of genomic composition among closely related species of the Neotropical cat genus Leopardus. We show strong evidence of ancient hybridization and introgression between the pampas cat (L. colocolo) and northeastern populations of tigrina (L. tigrinus), leading to remarkable cytonuclear discordance in the latter. In contrast, southern tigrina populations show recent and continuing hybridization with Geoffroy’s cat (L. geoffroyi), leading to extreme levels of interspecific admixture at their contact zone. Finally, we demonstrate that two seemingly continuous Brazilian tigrina populations show no evidence of ongoing gene flow between them, leading us to support their formal recognition as distinct species, namely L. tigrinus in the northeast and L. guttulus in the south

Invasive fungal diseases in haematopoietic cell transplant recipients and in patients with acute myeloid leukaemia or myelodysplasia in Brazil

AbstractInvasive fungal disease (IFD) shows distinct regional incidence patterns and epidemiological features depending on the geographic region. We conducted a prospective survey in eight centres in Brazil from May 2007 to July 2009. All haematopoietic cell transplant (HCT) recipients and patients with acute myeloid leukaemia (AML) or myelodysplasia (MDS) were followed from admission until 1 year (HCT) or end of consolidation therapy (AML/MDS). The 12-month cumulative incidence (CI) of proven or probable IFD was calculated, and curves were compared using the Grey test. Among 237 AML/MDS patients and 700 HCT recipients (378 allogeneic, 322 autologous), the 1-year CI of IFD in AML/MDS, allogeneic HCT and autologous HCT was 18.7%, 11.3% and 1.9% (p <0.001), respectively. Fusariosis (23 episodes), aspergillosis (20 episodes) and candidiasis (11 episodes) were the most frequent IFD. The 1-year CI of aspergillosis and fusariosis in AML/MDS, allogeneic HCT and autologous HCT were 13.4%, 2.3% and 0% (p <0.001), and 5.2%, 3.8% and 0.6% (p 0.01), respectively. The 6-week probability of survival was 53%, and was lower in cases of fusariosis (41%). We observed a high burden of IFD and a high incidence and mortality for fusariosis in this first multicentre epidemiological study of IFD in haematological patients in Brazil
