作者： Fabiana de Almeida andrade Caio fabio Schlechta Portella Anhembi Morumbi University Sao Paulo 01423-001 Brazil department of Naturology Anhembi Morumbi University Sao Paulo 06730-000 Brazil

The scientific literature presents a modest amount ot evidence m the use or complementary ana al[erna- tire medicine （CAM）. On the other hand, in practice, relevant results are common. The debates among CAM practitioners about the quality and execution of scientific research are important, Therefore, the aim of this review is to gather, synthesize and describe the differentiated methodological models that encompass the complexity of therapeutic interventions. The process of bringing evidence-based medicine into clinical practice in CAM is essential for the growth and strengthening of complementary medicines worldwide.

Canine mammary tumors (CMT) are very common in female dogs, representing approximately 50% of all tumors in this species, but are highly uncommon in male dogs and are primarily related to hyperestrogenism. There is considerable scientific interest in the possible role of environmental contaminants in the etiology of mammary tumors, specifically in relation to synthetic chemical substances released into the environment to which living beings are either directly or indirectly exposed. In this study, the presence of pyrethroid insecticide was observed in adipose tissue adjacent to canine mammary tumors. High Precision Liquid Chromatography—HPLC was adapted to detect and identify environmental contaminants in adipose tissue adjacent to malignant mammary tumor in one male dog, Akita, 12 years old. After surgery, the mass was carefully examined for malignant neoplastic lesions. Five grams of adipose tissue adjacent to the tumor was collected to detect environmental contaminants. The pyrethroid was identified as tetramethrin, at 0.20 μg/g. This is the first report in which the environmental contaminant level was detectable in adipose tissue of this male dog with a malignant mammary tumor, by HPLC. Results suggest the possible involvement of pyrethroid in the canine mammary tumor carcinogenesis since this animal did not present any other tumor that could cause hyperestrogenism.

Background: Osteoarthritis is a slowly progressive and debilitating disease with high prevalence in adult population. Knee is one of the joints most affected by this disorder. There are several models for animals’ osteoarthritis induction, however it is not identified any paper that compares these techniques. The present study was aimed to define the most appropriate model for rats osteoarthritis induction. Material and Methods: 40 Wistar rats were distributed into 4 groups of 10 animals each: normality group (NG);meniscectomy group (MG);quinolone group (QG) and iodoacetate group (IG). Radiographic images of the rat’s knees were analyzed as well as the amount of chondrocytes in the epiphyseal and articular cartilage. Results: In the radiographic analysis, there was a low correlation between the raters. Regarding the amount of chondrocytes in the epiphyseal cartilage, it was noticed that the IG and QG groups had fewer chondrocytes than NG, in contrast to MG that reported similar results to normality (p > 0.05). There was no significant difference between IG and QG groups (p > 0.05). Regarding the amount of chondrocytes in articular cartilage, it was noticed that the IG group showed fewer chondrocytes than NG (p 0.05). There was no significant difference between QG and MG groups (p > 0.05). Conclusion: Intraarticular injection of iodoacetate in rats is the model with greatest effect on reduction of chondrocytes amount.

AIM To present clinical characteristics from renal transplant recipients with dengue fever and its impact on graft *** We retrospectively evaluated 11 renal transplant recipients(RTR) with dengue infection confirmed by laboratory test, between January 2007 and July 2012, transplanted in the Renal Transplant Center of Walter Cantídio University Hospital from Federal University of Ceará. RESULTS Positive dengue serology(IgM) was found in all patients. The mean time between transplant and dengue infection was 43 mo. Fever was presented in all patients. Nine patients presented with classical dengue and two(18%) with dengue hemorrhagic fever. All cases had satisfactory evolution with complete recovery of the symptoms. The time for symptom resolution varied from 2 to 20 d, with an average of 9 d. An increase of creatinine after the infection was observed in three(27.2%) patients with no clinically impact on the kidney graft function. CONCLUSION RTR with dengue infection seems to have a clinical presentation and evolution similar to those seen in the general population, with no long-term damage to patient and to the graft.

Biodiesel Production from Waste Cooking Oil by Enzymatic Catalysis Process

Journal of Chemistry and Chemical Engineering 2013年第10期7卷 993-1000页

作者： Ignacio Contreras andrade fabio Emiro Sierra Vargas Carlos Alberto Guerrero Fajardo department of Biology and Chemistry University of Sinaloa Culiacan 80007 Mexico department of Chemistry National University of Colombia Bogota 11001 Colombia

Biodiesel is an excellent option for reducing dependence on fossil fuels with environmental advantages by reducing hazardous emissions. The enzymatic transesterification has attracted the attention of researchers in the last decade and the advantages of enzymatic catalysis show that the production of biodiesel by this route has good potential, mainly because it is friendly environment. For biodiesel, production process by enzyme catalysis is chosen the response surface methodology. It is an experimental strategy to find the best operating conditions of transesterification reaction to improve the biodiesel quality. The process has three variables: temperature, molar ratio oil-alcohol and catalyst quantity. The process was monitored by GC-FID (gas chromatography with flame ionization detector). The yield of the transesterification reaction by enzymatic catalysis decreases with increasing temperature, and may be due to inactivation of the enzyme by denaturation at temperatures above 50 °C. The second-order design used was the "CDC (central design composition)" which produced a maximum yield of 95.5% in the transesterification reaction by enzymatic catalysis obtained at a temperature of 45 °C, molar ratio methanol: oil of 8:1 and a catalyst loading of 8% wt.

Computational Simulation to Predict the Syngas Composition Produced during Charcoal Gasification

引用

Journal of Chemistry and Chemical Engineering 2014年第9期8卷 889-897页

作者： Ignacio Contreras-andrade Santiago Ramirez-Rubio Jonathan Parra-Santiago fabio Sierra-Vargas Carlos Alberto Guerrero-Fajardo Doctor Chemical Engineering Autonomous University of Sinaloa Culiacan Rosales 80040 Mexico department of Aeronautical Engineering San Buenaventura University Bogota 11001 Colombia Chemical Engineering (C) National University of Colombia Bogota 11001 Colombia Oepartment of Mechanical Engineering National University of Colombia Bogota 11001 Colombia Chemical Engineering and Mechanical Master in Environmental Engineering PhD in Chemical Engineering National Universityof Colombia Bogota 11001 Colombia

Charcoal gasification could mitigate the energetic problems in the rural zones since these regions have considerable amounts of wood, which is the base of such a fuel available. This paper presents some CFD (computational fluid dynamic) predictions of the experimental results obtained from the fixed bed gasification of charcoal made in a pilot-scale downdraft reactor using air, which was designed and built by the Research Group in Clean development Mechanisms and Energy Management, from the National University of Colombia. The quality of the syngas obtained from the process was evaluated through the CO and CO2 percentages measured in its composition. The performance at various air flow rates (measured at the system entrance, through an analog flow meter) is evaluated with the help of 11 thermocouples, which give the information to create a temperature profile, and three load cells to measure the solid fuel conversion rate. To simulate the process, the information from temperature profile, charcoal proximate analysis, air flow meter and load cells were taken as inputs and the syngas composition was obtained as the result from the calculation. The domain was defined as 2D with an axis-symmetric description, using quads as mesh elements. The calculation and results were performed in a CFD commercial code widely used for this type of simulations: ANSYS FLUENT. The predictions made by the software were validated with the experimental results obtained in the laboratory.
