Electrochemical synthesis of mesoporous CoPt nanowires for methanol oxidation

A new electrochemical method to synthesize mesoporous nanowires of alloys has been developed. Electrochemical deposition in ionic liquid-in-water (IL/W) microemulsion has been successful to grow mesoporous CoPt nanowires in the interior of polycarbonate membranes. The viscosity of the medium was high, but it did not avoid the entrance of the microemulsion in the interior of the membrane"s channels. The structure of the IL/W microemulsions, with droplets of ionic liquid (4 nm average diameter) dispersed in CoPt aqueous solution, defined the structure of the nanowires, with pores of a few nanometers, because CoPt alloy deposited only from the aqueous component of the microemulsion. The electrodeposition in IL/W microemulsion allows obtaining mesoporous structures in which the small pores must correspond to the size of the droplets of the electrolytic aqueous component of the microemulsion. The IL main phase is like a template for the confined electrodeposition. The comparison of the electrocatalytic behaviours towards methanol oxidation of mesoporous and compact CoPt nanowires of the same composition, demonstrated the porosity of the material. For the same material mass, the CoPt mesoporous nanowires present a surface area 16 times greater than compact ones, and comparable to that observed for commercial carbon-supported platinum nanoparticles.

Absorption and pharmacokinetics of grapefruit flavanones in beagles

The present study evaluated the pharmacokinetics of three different grapefruit flavanone forms in dog plasma and demonstrated their absorption after an oral intake of a grapefruit extract; pharmacokinetic parameters of these forms were also determined. Ten healthy beagles were administered 70 mg citrus flavonoids as a grapefruit extract contained in capsules, while two additional dogs were used as controls and given an excipient. The grapefruit flavanone naringin, along with its metabolites naringenin and naringenin glucuronide, was detected in dog plasma. Blood samples were collected between 0 and 24 h after administration of the extract. Naringin reached its maximun plasma concentration at around 80 min, whereas naringenin and naringenin glucuronide reached their maximun plasma concentrations at around 20 and 30 min, respectively. Maximum plasma concentrations of naringin, naringenin and naringenin glucuronide (medians and ranges) were 0·24 (0·05 2·08), 0·021 (0·001 0·3) and 0·09 (0·034 0·12) mmol/l, respectively. The areas under the curves were 23·16 l (14·04 70·62) min £ mmol/for nariningin, 1·78 (0·09 4·95) min £ mmol/l for naringenin and 22·5 (2·74 99·23) min £ mmol/l for naringenin glucuronide. The median and range values for mean residence time were 3·3 (1·5 9·3), 2·8 (0·8 11·2) and 8·0 (2·3 13·1) h for naringin, naringenin and naringenin glucuronide, respectively. The results of the present study demonstrate the absorption of grapefruit flavanones via the presence of their metabolites in plasma, thus making an important contribution to the field since the biological activities ascribed to these compounds rely on their specific forms of absorption.

Absorption and pharmacokinetics of green tea catechins in beagles

The present study evaluates for the first time in dogs, the kinetics of green tea catechins and their metabolic forms in plasma and urine. Ten beagles were administered 173 mg (12·35 mg/kg body weight) of catechins as a green tea extract, in capsules. Blood samples were collected during 24 h after intake and urine samples were collected during the following periods of time: 02, 26, 68 and 824 h. Two catechins with a galloyl moiety and three conjugated metabolites were detected in plasma. Most of the detected forms in plasma reached their maximum plasma concentration (Cmax) at around 1 h. Median Cmax for (2)-epigallocatechin-3-gallate (EGCG), (2)-epicatechin-3-gallate (ECG), (2)-epigallocatechin glucuronide (EGCglucuronide), (2)-epicatechin glucuronide (EC-glucuronide), (2)-epicatechin sulphate (EC sulphate) were 0·3 (range 0·11·9), 0·1 (range 00·4), 0·8 (range 0·23·9), 0·2 (range 0·1 1·7) and 1 (range 0·33·4) mmol/l, respectively. The areas under the plasma concentration v. time curves (AUC0!24) were 427 (range 1021185) mmol/l £ min for EGC-glucuronide, 112 (range 53919) mmol/l £ min for EC-sulphate, 71 (range 26306) mmol/l £ min for EGCG, 40 (range 12258) mmol/l £ min for EC-glucuronide and 14 (range 0·1124) mmol/l £ min for ECG. The values of mean residence time (MRT0!24) were 5 (range 216), 2 (range 111), 10 (range 213), 3 (range 216) and 2·4 (range 118) h for EGCG, ECG, EGC-glucuronide, EC-glucuronide and EC sulphate, respectively. In urine, catechins were present as conjugated forms, suggesting bile excretion of EGCG and ECG. Green tea catechins are absorbed following an oral administration and EGC-glucuronide is the metabolic form that remains in the organism for a longer period of time, suggesting that this compound could suffer an enterohepatic cycle.

Studies on the characterization of dental whitening process by using both hyperspectral imaging and colorimeter techniques

A beautiful smile is directly related with white teeth. Nowadays oral care has increased and developed processes for beautiful smiles. Dental bleaching is frequently used in odontology, not just for health care also for aesthetic treatment. With the possibility of teeth bleaching, now the importance is in, how white the tooth is? Because color is relate to an individual perception. In order to assets teeth correct color identification has been developed many color guides, models, spaces and analytical methods. Spite all of these useful tools the color interpretation depends on environmental factors, position of the sample in the data acquisition and most importantly the instrument sensitivity. The commons methods have proved to be useful. They are easy to handle, some are portable but they do not have a high sensitivity. The present work is based on the integration of a new analytical technique for color acquisition. High spectral Image (HSI) is able to performed image analysis with high quality and efficiency. HSI is used in many fields and we used it for color image analysis within the bleaching process. The main comparison was done with the HSI and the colorimeter through the processes of two different bleaching protocols. The results showed that HSI has higher sensitivity than the colorimeter. During the analysis the dental surface with the HSI we were able to notice surface changes. These changes were analyzed by roughness studies.

Seleção de genótipos de aceroleira assistida por marcadores isoenzimáticos visando à resistência a Meloidogyne incognita raça 2

A cultura da aceroleira despertou um grande interesse do mercado consumidor, tendo em vista o alto teor de vitamina C (ácido ascórbico), que varia entre 1.325 a 2.250 mg por 100 mL de suco. Com a expansão da cultura, surgiram problemas fitossanitários, entre os quais a infecção das raízes da aceroleira por nematóides. Os produtos químicos utilizados no controle dos nematóides são agressivos ao meio ambiente, e a seleção de genótipos resistentes e tolerantes constitui-se na melhor alternativa para a solução do problema. O trabalho foi desenvolvido em casa de vegetação com 18 genótipos de aceroleira, com o objetivo de encontrar genótipos resistentes e tolerantes a Meloidogyne incognita raça 2 assistida por marcadores isoenzimáticos, para indicar plantas destinadas a porta-enxerto. A avaliação foi realizada 60 dias após a inoculação mediante análise das variáveis: número de ovos por planta e por grama de raiz, índice de galhas e massa de ovos, biomassa fresca relativa do sistema radicular e biomassa fresca relativa da parte aérea. Os resultados permitiram identificar o genótipo 023-CMF como menos suscetível, e os genótipos 027-CMF e 035-CMF, como mais suscetíveis. Estudos realizados através da eletroforese isoenzimática com os sistemas α esterase, fosfatase ácida e peroxidase, 20; 40 e 60 dias após a inoculação com ovos de M. incognita raça 2, possibilitaram relacionar a expressão de proteínas com a suscetibilidade. Os genótipos mais próximos geneticamente, com índice de similaridade 0,941, foram 027-CMF e 026-CMF, 046-CMF e 026-CMF, e 041-CMF e 026-CMF. O menor índice de similaridade genética (0,115) foi observado entre os genótipos 002-SPE e 036-CMF.
