1. Modelagem da Distribuição Potencial de Mangifera indica L. sob Cenários Climáticos Futuros no Bioma Caatinga
Resumo Mangifera indica L. (mangueira) é uma planta exótica invasora na região Nordeste do Brasil. No estado do Ceará sua presença merece particular atenção na área de Proteção Ambiental (APA) da Serra de Baturité (setor norte do Estado). O sinergismo da bioinvasão com o aquecimento do sistema climático somado ao parco conhecimento sobre a distr

2. Low-intensity laser therapy improves tetanic contractions in mouse anterior tibialis muscle injected with Bothrops jararaca snake venom
Abstract Introduction Envenomation by Bothrops snakes can produce local pain, edema, hemorrhage and myonecrosis. However, standard antivenom therapy is generally ineffective in neutralizing these effects so that alternative methods of treatment have been investigated. In experimental animals, low-level laser therapy (LLLT) attenuates the local effects of Bo

3. Myocardial contractility impairment with racemic bupivacaine, non-racemic bupivacaine and ropivacaine. A comparative study
PURPOSE: To study racemic bupivacaine, non-racemic bupivacaine and ropivacaine on myocardial contractility. METHODS: Isolated Wistar papillary muscles were submitted to 50 and 100 mM racemic bupivacaine (B50 and B100), non-racemic bupivacaine (NR50 and NR100) and ropivacaine (R50 and R100) intoxication. Isometric contraction data were obtained in basal cond

4. Detrusor after-contraction: a new insight
ABSTRACT Aims: Detrusor after-contractions (DAC) are non-common in adults. Both definition (nothing in ICS reports) and significance (artefact, link with detrusor overactivity (DO) or bladder outlet obstruction (BOO)) remain discussed. Our purpose was to carry out an analysis of the urodynamic parameters during voidings wi

5. Effect of the 5-HT4 receptor and serotonin transporter on visceral hypersensitivity in rats
Visceral hypersensitivity plays an important role in motor and sensory abnormalities associated with irritable bowel syndrome, but the underlying mechanisms are not fully understood. The present study was designed to evaluate the expression of the 5-HT4 receptor and the serotonin transporter (SERT) as well as their roles in chronic visceral hypersensitivity

6. Relação entre estrutura e função muscular de membros superiores em pacientes com doença pulmonar obstrutiva crônica. / Relation between structure and muscular function of superior members in patients with pulmonary illness obstrutiva chronicle.
Chronic obstructive pulmonary disease (COPD) is a preventable and treatable disease characterized by airflow limitation that is not fully reversible. COPD is also characterized by exercise intolerance which can be caused by multiple factors. Quadriceps femoris is the most commonly muscle studied in skeletal muscle dysfunction syndrome in COPD. However, it ha

7. Isolamento e caracterizaÃÃo parcial dos Genes beta-actina e miosina de cadeia pesada do CamarÃo rosa Farfantepenaeus subtilis / Isolation and partial characterization of genes beta-actin and myosin heavy chain shrimp Farfantepenaeus subtilis
The penaeid shrimp Farfantepenaeus subtilis is an important native species for fisheries industry in Brazil. Among marine shrimps of commercial importance, penaeids are recognized as a valuable resource for fishery and aquaculture in tropical and subtropical regions. However, data on these species is extremely reduced, especially concerning genetic elements

8. Estudo dos mecanismos genéticos e celulares durante a fase inflamatória do processo de regeneração tecidual em animais selecionados geneticamente para a máxima resposta inflamatória aguda homozigotos para os alelos R ou S do gene Slc11a1. / Study of genetic and cellular mechanisms during the inflammatory phase of tissue regeneration process in animals genetically selected for maximum acute inflammatory response homozygous for Slc11a1 R and S alleles.
Homozygous AIRmax and AIRmin sublines for Slc11a1 R and S alleles present distinct regenerative capacity to the ear hole. AIRmaxSS mice exhibited early tissue regeneration compared to AIRmaxRR animals, suggesting that the Slc11a1 S allele promotes regeneration in these animals. AIRmin sublines didnt show regeneration after ear punch. In response to the stimu

9. Existence and Uniqueness of a Fixed-Point for Local Contractions
This paper proves the existence and uniqueness of a fixed-point for local contractions without assuming the family of contraction coefficients to be uniformly bounded away from 1. More importantly it shows how this fixed-point result can apply to study existence and uniqueness of solutions to some recursive equations that arise in economic dynamics.

10. Caracterização fisico-química de adobe estabilizado com amido de mandioca
Due to the high habitational Brazilian shortage, traditional technologies of earth construction and constructive elements production have been rescue, having the soil as a principal raw material. Between these traditional technologies, there are the adobes, which consist of soil blocks with regional variable size. The soil material is removed, humidified, tr

11. Biological effects induced by Tityus serrulatus crude venom and its toxins TsTx-V, gamma toxin and natriuretic peptide / Efeitos biolÃgicos induzidos pelo veneno total de Tityus serrulatus e suas fraÃÃes TsTx-V, toxina gama e peptÃdeo natriurÃtico
The venom of Tityus serrulatus has a mixture of toxic and non toxic peptides presenting diverse systemic and local effects. The aim of this work was to investigate the cardiovascular and renal effects promoted by the crude venom of the scorpion Tityus serrulatus and its isolated components such as Tityus serrulatus toxin V (TsTx-V), Gamma Toxin and the newly

12. Contributions of perfusion and myocardic cintilography function with double isotope and low dobutamina dose validity: evaluation of cellular integrity and contractile reserve in viable myocardium identification / Contribuições da cintilografia de perfusão e função miocárdica com duplo isótopo na vigência de baixa dose de dobutamina: avaliação da integridade celular e reserva contrátil na identificação do miocárdio viável
Em pacientes portadores de insuficiência coronariana com prognóstico desfavorável pela presença de disfunção ventricular significativa, a pesquisa de viabilidade miocárdica traz contribuições ao predizer a possibilidade de recuperação contrátil após revascularização. Os segmentos miocárdicos com disfunção contrátil por hipoperfusão podem
