ABSTRACT A March male Golden, weighing 7.6kg, presented with gradual weight loss, high body temperature, depression, poor appetite and thirst, and vomiting before consultation. The results showed that the erythrocytes, hematocrit, hemoglobin, and platelets were lower than the reference values. The diagnosis of mixed infection with haematocrit and eosinophilic bodies was confirmed by real-time fluorescence PCR of whole blood, which was positive for haematocrit and eosinophilic bodies. The dog was treated with doxycycline and ceftriaxone, and the dog fully recovered after 2 weeks with blood transfusion, symptomatic treatment, and supportive therapy. This indicates that the disease can be treated well by a comprehensive treatment approach.

RESUMO Um March Golden macho, pesando 7,6kg, apresentou perda de peso gradual, temperatura corporal alta, depressão, falta de apetite e sede, e vômitos antes da consulta. Os resultados mostraram que os eritrócitos, hematócrito, hemoglobina e plaquetas eram menores que os valores de referência. O diagnóstico de infecção mista com hematócrito e corpos eosinófilos foi confirmado por PCR de fluorescência em tempo real de sangue total, o que foi positivo para hematócrito e corpos eosinófilos. O cão foi tratado com doxiciclina e ceftriaxona, e o cão recuperou-se completamente após duas semanas com transfusão de sangue, tratamento sintomático e terapia de suporte. Isto indica que a doença pode ser bem tratada através de uma abordagem de tratamento abrangente.

ABSTRACT Purpose To investigate the incidence and pathologic characteristics of prostate cancer (PCa) incidentally discovered at the time of radical cystectomy and its impact on overall survival. Materials and Methods A single center retrospective study of 762 male patients who underwent radical cystoprostatectomy from Jan 1994 to Dec 2012. Results Of all included patients, 132 (17.3%) were found to have PCa. Patients with incidental PCa had a significantly higher mean age (69.2 vs. 62.2 years, P=0.015). Among the 132 patients with PCa, prostate specific antigen (PSA) analysis was available in 76 patients (57.6%), with a median value of 1.06ng/mL, and 61 (80.3%) patients had a PSA value below 4ng/mL. Four hundred and thirty-six patients (57.1%) were successfully followed, with a median duration of 46.5 months. The overall 5-year survival rate was 62.1%, and the 5-year cancer–specific survival rate was 72%. PCa recurrence was defined by two consecutive PSA values of >0.2 ng/mL and rising, and no PCa recurrence occurred. According to a univariate analyses, incidental PCa was not associated with cancer-specific survival (P=0.192) or overall survival (P=0.493). According to univariate analyses, the overall survival of patients with PCa was not associated with prostate cancer staging, PSA value, or Gleason score (All P values>0.05). Conclusions Prostate cancer incidentally discovered at the time of radical cystectomy does not decrease overall survival. Patients with incidental PCa were older than those without. The PSA value before operation is not helpful for predicting incidental prostate cancers.

Abstract. 3-Alkylindoles have been prepared in 91~99% excellent yields by alkylation of indoles with epoxides or alcohols catalyzed by the recyclable heteropoly acid based supported functionalized ionic liquid H2PMo12O40-NMPIL@SiO2 under heterogeneous catalysis at room temperature. The influence of various reaction parameters including catalyst selection, catalyst amount, reaction time, solvent, and reaction temperature were studied. The heterogeneous supported catalyst was easily recoverable by filtration, and could be used for six consecutive runs without significant loss in catalytic activity. This study demonstrated a green and highly efficient chemistry technology in the preparation of 3-alkylindoles.

Resumen La alquilación de indoles con epóxidos o alcoholes permite la preparación de 3-alquilindoles con rendimientos que van del 91 al 99% de rendimiento empleando el líquido iónico H2PMo12O40-NMPIL@SiO2 en condiciones heterogéneas a temperatura ambiente. Se estudió la influencia de varios parámetros de reacción como la selección del catalizador, la cantidad de este, el tiempo de reacción, el disolvente usado y la temperatura de reacción. El catalizador heterogéneo se recupera por filtración y puede emplearse seis veces consecutivas sin pérdida significativa de su capacidad catalítica. Esta es una muestra de una tecnología verde y eficiente para la preparación de 3-alquilidoles.

Abstract: A series of silica supported functionalized ionic liquid catalysts have been prepared and tested in the hydroxylation of aromatics to phenols with H2O2 under solvent-free conditions. The properties of the heterogeneous catalytic system were studied by tuning various reaction parameters including selection of catalyst, amount of the catalyst, influences of reaction time and temperature. Among the catalysts, CuCl3-IL-SiO2 exhibited the highest efficiency in the hydroxylation of aromatics to phenols under the optimized condition along with good recycle performance.

Se estudiaron las propiedades del sistema catalítico heterogéneo modificando varios parámetros de reacción como tipo y cantidad de catalizador, influencia en el tiempo de reacción y temperatura. Entre los catalizadores, CuCl3-IL-SiO2, presenta la mayor eficiencia en la hidroxilación de compuestos aromáticos a fenoles bajo las condiciones optimizadas así como un buen reciclado.

Um arranjo de nanotubos de óxido de titânio alinhados verticalmente foi gerado com sucesso na superfície de um substrato de titânio pela técnica de anodização. Os nanotubos foram caracterizados por microscopia eletrônica de varredura (MEV), difratometria de raios X de pó (DRX), espectroscopia Raman e espectroscopia de fotoluminescência. Os resultados indicam que o tamanho dos nanotubos de óxido de titânio é altamente dependente da voltagem aplicada e que suas propriedades de fotoluminescência são fortemente influenciadas pela estrutura cristalina. Adicionalmente, efeitos quânticos de tamanho estão presentes nas propriedades dos nanotubos de TiO2.

An array of vertically aligned titanium oxide nanotubes was successfully grown on the surface of a titanium substrate by the anodization technique. The nanotubes were characterized by scanning electron microscopy (SEM), powder X-ray diffractometry (XRD), Raman spectroscopy and photoluminescence spectroscopy (PL). The results indicate that the size of the titanium oxide nanotube is greatly dependent on the applied voltage, and its photoluminescence properties are strongly influenced by the crystal structure. In addition, it is shown that quantum size effects are present in the optical properties of TiO2 nanotubes.
