1. Immunophenotyping, plasticity tests and nanotagging of stem cells derived from adipose tissue of wild rodent agouti (Dasyprocta prymnolopha)
RESUMO Há um interesse crescente no estudo das células estaminais mesenquimais, não especializadas, pois ainda existem algumas discussões sobre seu comportamento in vitro. A medicina regenerativa é uma ciência em fase de crescimento que desenvolve tratamentos como terapia celular utilizando células estaminais somáticas. Em vários estudos, o tecido a

2. Hormonal Biomarkers for Evaluating the Impact of Fetal Growth Restriction on the Development of Chronic Adult Disease
Resumo A hipótese das origens fetais de doenças em adultos propõe que distúrbios crônicos metabólicos, incluindo doenças cardiovasculares, diabetes e hipertensão, se originam na plasticidade do desenvolvimento devido a insultos intrauterinos. Estes processos envolvem uma resposta adaptativa do feto amudanças nos sinais ambientais que podem promover

3. Leaf Morphological Plasticity of Tree Species from Two Developmental Stages in Araucaria Forest
This study compared the morphological and anatomical variations of the leaves of four shade-tolerant tree species Allophylus edulis (St.-Hil.) Radlk (Sapindaceae), Casearia sylvestris Sw. (Salicaceae), Cupania vernalis Cambess. (Sapindaceae) and Luehea divaricata Mart. (Malvaceae) from a fragment of Araucaria forest in two developmental stages. Morphological

4. Phenotypic plasticity and fitness in egg parasitoids
Several proxies can be used to estimate the fitness of egg parasitoids: size, longevity, fecundity, mating ability and vagility. All these proxies are positively correlated with the lifetime fitness gain of an individual. However, the phenotypic plasticity, which is the ability of a genotype to produce distinct phenotypes depending on environmental condition

5. Survivorship rates of adult Anolis mariarum (Squamata: Polychrotidae) in two populations with differing mean and asymptotic body sizes
We compared adult survivorships in two populations of the lizard Anolis mariarum with different mean and asymptotic body sizes to examine one prediction of age-specific mortality theory; that populations that experience higher adult mortality should exhibit earlier maturation and smaller adult body sizes. We used a maximum likelihood approach to evaluate dif

6. Life cycle of Poratia salvator (Diplopoda: Polydesmida: Pyrgodesmidae)
Even though millipedes display high plasticity in their reproductive strategies, they are poorly studied in the tropical region. The present study describes the biological cycle and reports the parthenogenetic reproduction of Poratia salvator Golovatch & Sierwald, 2000 under environmental conditions. Collections were carried out in Pantanal of Mato Grosso an

7. NMDA receptor blockade alters the intracellular distribution of neuronal nitric oxide synthase in the superficial layers of the rat superior colliculus
Nitric oxide (NO) is a molecular messenger involved in several events of synaptic plasticity in the central nervous system. Ca2+ influx through the N-methyl-D-aspartate receptor (NMDAR) triggers the synthesis of NO by activating the enzyme neuronal nitric oxide synthase (nNOS) in postsynaptic densities. Therefore, NMDAR and nNOS are part of the intricate sce

8. Influence of Glatiramer acetate on the synaptic stability and glial reaction during the EAE and after motor root avulsion / Influencia do acetato de glatiramer (AG) sobre a estabilidade sinaptica e reação glial durante o curso da EAE e apos avulsão de raizes motoras
Multiple sclerosis (MS) is an inflammatory and demyelinating disease, which etiology is unknown. Although it is the result of a major autoimmune response. The Glatiramer acetate (GA) is a drug used to treat MS and is composed by four peptides homologous to the myelin basic protein (MBP), that is able to reduce the exacerbation and injuries to the CNS. Nevert

9. Comparação e descrição de parâmetros acústicos do canto de Volatinia jacarina (Aves: Emberizidae) no contexto de seleção sexual
Bird songs may convey information about the quality of the male, and females can access this information during partner choice. The aim of this study was to test for correlations between acoustic parameters of songs from Volatinia jacarina males and their physical attributes. First we determined, through quantitative analysis, the degree of stereotypy in the

10. Opioidergic modulation of behavioral selection during lactation / Modulação opioidérgica na seleção comportamental após o parto
Treatment of postpartum female rats with morphine inhibits maternal behavior. The same treatment also stimulates foraging in adult animals. Exposure to drugs of abuse may result in a progressive and enduring enhancement of their reinforcing effects. Puerperal treatment with morphine leads to reverse tolerance to this drug, ultimately influencing the effects

11. Ontogenia craniana comparada de Arctocephalus australis, Callorhinus ursinus e Otaria byronia (Otariidae: Pinnipedia)
The search for mechanisms that can generate major morphological changes has led to the study of ontogeny, in part because some kinds of modifications of ontogenies seem an excelent way to generate major phenotypic change. We focus here on Arctocephlaus australis, Callorhinus ursinus and Otaria byronia with the aim of contributing to the understanding of the

12. Bioecological studies on Tamarixia radiata (Waterston, 1922) (Hymenoptera: Eulophidae) in the control of Diaphorina citri Kuwayama, 1907 (Hemiptera: Psyllidae) / Estudos bioecológicos de Tamarixia radiata (Waterston, 1922) (Hymenoptera: Eulophidae) para o controle de Diaphorina citri Kuwayama, 1907 (Hemiptera: Psyllidae)
Since 2004, have been detected in citrus-growing areas of São Paulo, the bacterias that are responsible for the main disease of citrus worldwide, known as greening or huanglongbing. The widespread distribution in Brazil of the vector psyllid, Diaphorina citri and the presence of the pathogen in citrus-growing areas is a limiting factor for production. Tamar
