2. Agaricus subrufescens: substratum nitrogen concentration and mycelial extraction method on antitumor activity
ABSTRACT Antitumor activity of Agaricus subrufescens has been shown on vegetative mycelium and basidiocarp. However, few studies have assessed the effect of A. subrufescens cultivation conditions and extraction methods on antitumor activity. This study evaluated the effect of nitrogen concentration on the cultivation medium of A. subrufescens and the extract

3. Evidence of phenotypic plasticity of larvae of Simulium subpallidum Lutz in different streams from the Brazilian Cerrado
In this paper, the overall morphological differences between populations of Simulium subpallidumLutz, 1909 are studied. Several studies found in the literature point to a relationship between the labral fans and body size and the habitat where blackfly larvae occur. However, other characteristics potentially related to the microhabitat, such as abdominal hoo

4. Description of the first species of Metharpinia (Crustacea: Amphipoda: Phoxocephalidae) from Brazil
A new amphipod species of Metharpinia Schellenberg, 1931 is described from Campos Basin, southeastern Brazilian coast. The material was collected with van Veen grab from unconsolidated substratum, off the mouth of the Paraíba do Sul River. The new species can be distinguished from its congeners by presenting a strongly constricted rostrum and a slender palp

5. Involvement of memory T-cells in the pathophysiology of chronic lymphocytic leukemia
The role of T-cells in the pathogenesis of chronic lymphocytic leukemia has recently gained much attention due to the importance of the constant interaction between neoplastic B-cells with microenvironment substratum and T-cells. It is believed that these interactions modulate the clinical course of the disease, mainly through the regulation of the expansion

6. Influence of substratum position and acquired pellicle on Candida albicans biofilm
The purpose of this study was to evaluate the influence of the substratum position and the saliva acquired pellicle (AP) on Candida albicans biofilm development. Poly(methylmethacrylate) (PMMA) disks were fabricated and randomly allocated to experimental groups: HNP (disks placed in a horizontal position and uncoated by pellicle), VNP (disks placed in a vert

7. Benefits of oxygen and nitrogen plasma treatment in Vero cell affinity to poly(lactide-co-glycolide acid)
Cell adhesion on materials surface is critical because this phenomenon occurs before other events, as cell spreading, cell migration and cell differentiation. it is commonly accepted that the adhesion of cells on solid substrate is influenced by several substratum surface properties, such as wettability, surface charge, roughness and topography. plasma techn

8. Reduction of Aeromonas hidrophyla biofilm on stainless stell surface by essential oils
This study demonstrates the possibility of using sanitizing detergents based on natural products for the elimination and/or reduction of Aeromonas hydrophila biofilm formed on stainless steel surfaces. The goal of this work was to determine the reduction effect of sanitizing detergents containing essential oils of Thymus vulgaris (thyme) and Cymbopogon citra

9. Entomofauna aquática do Ribeirão das Anhumas (Bacia hidrográfica do Rio Mogi-Guaçú, SP) : influência do represamento e do uso da terra na estrutura da comunidade
Alterações em bacias hidrográficas, como o desmatamento da vegetação ripária, a expansão das atividades agrícolas e a construção de represas, são exemplos das interferências antrópicas, que interferem na diversidade de insetos aquáticos nos córregos e rios. O presente estudo teve como objetivo investigar padrões de distribuição de comunidad

11. Efeito da radiação gama em propriedades da farinha de banana verde / Effect of gamma radiation in properties of green banana flour
Banana starch has been researched in the area of nutrition from the introduction of the Resistant Starch concept (RS). The starch of Musa AAA-Nanicão and Musa AAB-Terra had been already characterized in relation to their physiological responses. Green banana possesses important amount of resistant starch. The main interest in relation to the resistant starc

12. Production flush of Agaricus blazei on Brazilian casing layers
This study aimed to verify the biological efficiency and production flushes of Agaricus blazei strains on different casing layers during 90 cultivation days. Four casing layers were used: mixture of subsoil and charcoal (VCS), lime schist (LSC), São Paulo peat (SPP) and Santa Catarina peat (SCP); and two genetically distant A. blazei strains. The fungus was
