13. Protective effect of maternal prenatal melatonin administration on rat pups born to mothers submitted to constant light during gestation
We studied the effects of adverse conditions such as constant light (LL) on the circadian rhythm of malate (MDH, EC 1.1.1.37) and lactate (LDH, EC 1.1.1.27) dehydrogenase activities of the testes of male Wistar rats on postnatal day 28 (PN28), anxiety-like behavior (elevated plus-maze test) at PN60 and sexual behavior at PN120. The rats were assigned to moth

14. Análise de expressão e splicing alternativo do gene Mdh-1 de Apis mellifera L. (Hymenoptera: Apidae)
Mdh-1 enzyme locus coding for cytoplasmic malate dehydrogenase has three common alleles Mdh-1100 (F), Mdh-180 (M) e Mdh-165 (S) and it has been extensively used as racial marker in populational studies of Apis mellifera. Additional isoforms are detected by electrophoretic analysis during ontogenetic development of A. mellifera, indicating differential expres

15. Isoenzyme variation in the leaf-cutting ants Acromyrmex heyeri and Acromyrmex striatus (Hymenoptera: formicidae)
This is the first study of isoenzyme variability in the leaf-cutting ants (Myrmicinae, Attini) Acromyrmex heyeri (Forel, 1899) and A. striatus (Roger, 1863) which are common throughout the southern Brazilian state of Rio Grande do Sul. We studied the alloenzyme variability of malate dehydrogenase (MDH), α-glycerophosphate dehydrogenase (α-GPDH) and amylase

16. Resposta metabólica aeróbia, anaeróbia e argininolítica do bagre Genidens Genidens, (Curvier, 1829), presentes nos estuários do município de Ubatuba / Aerobic, anaerobic and argininolitic metabolic response of the catfish Genidens genidens (Cuvier, 1829), present in esturaries of the municipality of Ubatuba
A resposta metabólica do bagre Genidens genidens de três estuários (rios Grande, Indaiá e Escuro) do município de Ubatuba SP foi estudada comparativamente em relação ao impacto da atividade humana na região. Encéfalo, fígado e músculo epaxial foram utilizados para determinar a atividade específica das enzimas lactato desidrogenase (LDH), malato d

17. Effects of ZmDof1 and OsDof25 transcriptional factors superexpression on nitrogen usage efficiency in Arabidopsis. / Efeito da superexpressão dos fatores de transcrição ZmDof1 e OsDof25 sobre a eficiência de uso de nitrogênio em Arabidopsis.
To improve nitrogen usage efficiency in plants the rice transcriptional factor OsDof25 was identified and cloned, whose probably orthologe is the maize ZmDof1, already identified and partially characterized. The ZmDof1 was also cloned for comparative analysis with OsDof25, in order to confirm this last one as ZmDof1 orthologe in rice. The constructions for A

18. ASPECTOS FISIOLÃGICOS E BIOQUÃMICOS DA MATURAÃÃO DE SEMENTES DE PIMENTÃO. / Physiological and biochemical aspects of the maturation of sweet pepper seeds
The determination of the appropriate point or interval for the harvest of fruits for sweet pepper seed production is fundamental for success in production programming, as well as for obtaining quality seeds. From their physiological maturity period up to the moment they are used for sowing, the seeds are subject to loss of physiological quality due to the oc

19. AlteraÃÃes fisiolÃgicas e bioquÃmicas durante desenvolvimento, germinaÃÃo e armazenamento em sementes de pimenta malagueta (Capsicum frutescens L.) e habanero yellow (Capsicum chinenses) / Physiological and biochemical changes during development, storage and germination in seeds of chilli pepper (Capsicum frutescens L.) and yellow habanero (Capsicum chinenses).
The cultivation of peppers, considered until recently as a secondary activity, has undergone major transformations and assumed great importance in the country, which led to significant increase in demand for seed quality. Being an emerging market is the need for research for the evaluation of technologies to be used in different stages of seed production. To

20. Soluble malate dehydrogenase of Geophagus brasiliensis (Cichlidae, Perciformes): isolated isoforms and kinetics properties
Kinetic properties and thermal stabilities of Geophagus brasiliensis skeletal muscle unfractionated malate dehydrogenase (MDH, EC 1.1.1.37) and its isolated isoforms were analyzed to examine a possible sMDH-B* locus duplication in a fixation process influenced by genetic drift. Two optimal pHs were detected: 7.5 for AB1 unfractionated muscle phenotype and it

24. Exsudação de ácido málico e alongamento radicular de genótipos de milho tratados com níveis tóxicos de alumínio / Malic exudation and root elongation in maize genotypes treated with toxic levels of aluminum
Aluminum effects on malic acid exudation and root elongation were evaluated in two maize genotypes: UFVM 100 e UFVM 200, selected from a group of six genotypes developed by the Agronomy Department of the Federal University of Viçosa, Viçosa, MG, Brazil. Five days-old seedlings of the six genotypes were exposed to Al 50 M in 0.4 mM CaCl2, pH 4.0, for 24 h a
