BACKGROUND Imitation SWItch (ISWI) ATPase is the catalytic subunit in diverse chromatin remodeling complexes. These complexes modify histone-DNA interactions and therefore play a pivotal role in different DNA-dependent processes. In Trypanosoma cruzi, a protozoan that controls gene expression principall...
BACKGROUND: Pollen development is an energy-consuming process that particularly occurs during meiosis. Low levels of adenosine triphosphate (ATP) may cause cell death, resulting in CMS (cytoplasmic male sterility). DNA sequence differences in ATP synthase genes have been revealed between the N- and S-cyt...

BACKGROUND: Karwinskia humboldtiana (Kh) is a poisonous plant of the rhamnacea family. To elucidate some of the subcellular effects of Kh toxicity, membrane fluidity and ATPase activities as hydrolytic and as proton-pumping activity were assessed in rat liver submitochondrial particles. Rats were randoml...

BACKGROUND: Nitrosative and oxidative stress play a key role in obesity and diabetes-related mitochondrial dysfunction. The objective was to investigate the effect of curcumin treatment on state 3 and 4 oxygen consumption, nitric oxide (NO) synthesis, ATPase activity and lipid oxidation in mitochondria i...

There are evidences that Bryconamericus aff. iheringii represents a species complex. DNA molecular markers have been effective in studies on phylogeny, taxonomy, and identification of cryptic species. In this study, partial sequences of genes of ATPase 6 and 8 were used to assess genetic diversity within...
Characidae is the largest and more diversified family from Characiformes and presents several classification problems, with several genera currently allocated as incertae sedis, such as the genus Hemigrammus. The upper Paraná river floodplain is an environment with high fish diversity. There is at least...
A transição morfológica de levedura para hifa é essencial para a virulência de Candida albicans. Esta transição envolve a expressão de genes hifa-específicos que estão sob o controle de fatores transcricionais. Para descobrir genes hifa-específicos utilizamos um método de triagem diferencial,...
Estudou-se em ratos normo (NWR) e hipertensos (SHR) jovens com idade de 14-16 semanas e adultos com 19-21semanas de idade as concentraçöes catiônicas de Mg2+, Ca2+, Zn2+ e tambem Na+ e K+ em miocárdio e músculo esquelético. As análises foram efetuadas em espectrofotômetro de absorçäo atômica. ...
Foram estudadas as alteracoes histoquimicas relativas ao grau de positividade da desidrogenase succinica, da desidrogenase lactica, da adenosina trifosfatase e da aldolase da fibra cardiaca do rato albino em estresse agudo. Os resultados obtidos indicam que, durante o estresse agudo, ha maior demanda met...
