MICROORGANISMS OF THE COCCIDIA SUBCLASS: RESISTANCE AND IMPLICATIONS FOR THE ASEPTIC PROCESSING OF HEALTHCARE PRODUCTS
(UNIV SAO PAOLOCERQUERA CESAR, 2013-08-02)
This theoretical study proposes a reflection on the intrinsic resistance of the subclass Coccidia, particularly the genus Cryptosporidium, considered to be potential pathogens for immunocompromised patients, and the ...
CHEMICAL DEGRADATION OF ESFENVALERATE AND HPLC-UV-PAD DETECTION OF INTERMEDIATES AND BY-PRODUCTS
(TAYLOR & FRANCIS INCPHILADELPHIA, 2012)
The impact of pyretroids, their by-products and degradation products on humans and the environment is recognized as a serious problem. Despite several studies regarding esfenvalerate toxicity and its detection in water and ...
Open circuit interaction of borohydride with oxidized platinum surfaces
(ELSEVIER SCIENCE INCNEW YORK, 2012)
An interesting method to investigate the effect of fuel crossover in low temperature fuel cells consists of studying the open circuit interaction between the reducing fuel and an oxide-covered catalyst. Herein we report ...
Glycerol as a by-product of biodiesel production in Brazil: Alternatives for the use of unrefined glycerol
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
On January 1 2008, Brazil included yet another element into its energy matrix: biodiesel. The predominant biodiesel production process involves a phase of transesterification that yields glycerol as a by-product. The use ...
Metalloporphyrins as cytochrome P450 models for chlorhexidine metabolite prediction
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The catalytic oxidation of chlorhexidine (CHX, a strong microbicidal agent) mediated by ironporphyrins has been investigated by using hydrogen peroxide, mCPBA, tBuOOH, or NaOCl as oxidant. All of these oxygen donors yielded ...
Dental Pulp Vascular Permeability Changes Induced by Dental Bleaching
(INST TECNOLOGIA PARANACuritiba, 2012-01)
Aiming to compare the effect of different light sources for dental bleaching on vascular permeability of dental pulps, forty-eight incisors were used. The bleaching agent (35% hydrogen peroxide) was activated by halogen ...
Crystal structure of Schistosoma purine nucleoside phosphorylase complexed with a novel monocyclic inhibitor
(ELSEVIER SCIENCE BV, 2010)
A novel inhibitor of Schistosoma PNP was identified using an ""in silico"" approach allied to enzyme inhibition assays. The compound has a monocyclic structure which has not been previously described for PNP inhibitors The ...
Synthesis, Infrared Spectroscopy and Crystal Structure Determination of a New Decavanadate
(SPRINGER/PLENUM PUBLISHERS, 2010)
Synthesis, infrared spectroscopy and crystal structure of a new potassium decavanadate decahydrate, K(6)[V(10)O(28)] 10H(2)O, has been reported The infrared spectrum is dominated by decavanadate polyanion and water bands ...
Adhesion as a tool for in-built nanotechnology design in cementitious materials
(KOREAN ASSOC CRYSTAL GROWTH, INC, 2010)
Confined water, such as those molecules in nanolayers of 2-3 nm in length, plays an important role in the adhesion of hydrophilic materials, mainly in cementitious ones. In this study, the effects of water containing ...
