No município de São Carlos, o importante manancial superficial do Rio Monjolinho tem as cabeceiras localizadas na região periurbana, com zona urbana consolidada, industrial e rural. Os aquíferos freáticos da sub-bacia, possuem importância dinâmica hidrológica, entretanto ainda sem investigação quanto à sua qualidade hidroquímica. Este trabalho buscou conhecer os impactos gerados pelas atividade...

Oxygen supply implies higher production cost and reduction of maximum theoretical yields. Thus, generation fermentation products is more cost-effective. Aiming to find a key piece for the (poly)-3-hydroxybutyrate (PHB) as product, here we characterize an acetoacetyl-CoA reductase, isolated from Candidatus Accumulibacter phosphatis-enriched mixed culture, showing (kcatNADH/KMNADH)/(kcatNADPH/KMN...

The crystal structure of strontium diarsenate has been reinvestigated from single-crystal X-ray diffraction data. In contrast to the previous determinations of this structure [Weil et al. (2009 ▶). Solid State Sci. 11, 2111-2117; Edhokkar et al. (2012 ▶). Mater. Sci. Eng., 28, 012017] and to all isotypic A 2 B 2O7 compounds that crystallize in the space group P41, the current redetermination re...

This paper proposes a new measure for similarity between basket datasets. The new measure is calculated from support counts using a formula inspired by information entropy. Experiments on both real and synthetic datasets show the effectiveness of the measure. This paper also studies the problem of finding a mapping between categorical database attribute sets using similarity measures. A generic...

Increased awareness of the importance of microRNAs goes hand in hand with an increased need to follow their expression. Their small size of 22 nucleotides makes tracking them a challenge that requires new approaches and technology. Neely and colleagues now developed a method for detection of microRNA expression using locked nucleic acid probes and a multicolor confocal laser system; they achiev...

Invariant (Ii) chain loss causes defective class II export, B cell maturation, and reduced DM stability. In this study, we compare Ii chain and class II mutant mouse phenotypes to dissect these disturbances. The present results demonstrate that ER retention of alphabeta complexes, and not beta-chain aggregates, disrupts B cell development. In contrast, we fail to detect class II aggregates in I...

OBJECTIVE Establishing the seroprevalence of Lyme disease in workers from Cordoba. MATERIAL AND METHODS Representative serum samples (152) were taken from the cities of Montería, Cereté, Lorica and Cotorra in the Córdoba department in Colombia. Borrelia burgdorferi antibodies were detected by ELISA and confirmed by western blot anti-Borrelia blot assay. RPR (rapid plasma regain) test for Trep...
