Influence of different cultivars on oil quality and chemical characteristics of avocado fruit

The objective of this paper was to determine the chemical composition of the avocado fruit of cultivars Fortuna, Collinson, and Barker and to carry out a detailed analysis of the fatty acid composition of the pulp, seed, and peel oils. The saturated fatty acid (SFA) of the pulp oils accounted for around 22.3, 29.4, and 41.3% of the total fatty acids in the Fortuna, Collinson and Barker cultivars, respectively, and these values indicate better quality of pulp oil of Fortuna and Collinson cultivars than that of the Barker cultivar. There was very little variation in the content monounsaturated fatty acids of the peel oils between the cultivars. However, the seed oil of the Collinson cultivar was the best since it contained the lowest (30.8% of total fatty acids) content of SFA, but it had very high concentrations of 9,12-octadecadienoic (23.9 to 29.4% of total fatty acids) and 9,12,15-octadecatrienoic (9.9 to 18.3% of total fatty acids) acids.

Sensory acceptability and fatty acid profile of fish crackers made from Carassius gibelio

Abstract In this study, our aim was to consider the production of fish crackers using Carassius gibelio and to investigate the fatty acid profile and sensory quality of the fish crackers. Fish cracker mixture with a ratio 3.5:1.5 (minced fish/wheat starch) was obtained. Based on the total minced fish and starch level, 1.75% salt, 0.25% black pepper, 2% sunflower oil, 1% baking powder and 10% cold water (4 °C) were added and stirred until a homogenous mixture was obtained. The mixture was compressed in an extractor and baked. The moisture content of minced fish (CMF), cracker dough (CD) and crackers (CCr) was 77.73 ± 0.14%, 63.10 ± 2.18% and 7.95 ± 0.67% respectively. The n6/n3 ratio of crackers was 2.61 ± 0.20, PUFA/SFA ratio 2.28 ± 0.06 and DHA/EPA ratio 1.81 ± 0.01. The overall acceptability score obtained by the sensory evaluation of panelists was very high (8.09 ± 0.25).

Use of intravascular ultrasonography for the characterization of coronary artery disease in patients with chronic kidney disease

INTRODUCTION: Chronic kidney disease patients present a very high cardiovascular mortality. Nevertheless, a comparative description of lesion characteristics, using intravascular ultrasound in dialysis patients, has not yet been reported. The objective of the present study was to analyze the plaque morphology through intravascular ultrasound in comparison to their counterparts with normal renal function. METHODS: Patients were screened for coronary artery disease, and the coronary angiography was performed when indicated. Plaque morphology was evaluated by ultrasound, and findings were compared to a group of patients with coronary artery disease, who presented normal renal function, it carefully matched for all Framingham risk factors and lesion location at the coronary artery tree. RESULTS: One hundred and thirty-nine patients from a single center of hemodialysis were screened for the study. Patients with coronary lesions confirmed at the angiography presented lower hemoglobin (10.8 ± 1.5 versus 12.0 ± 19; p < 0.046) levels and higher levels of low-density lipoprotein (110.6 ± 25.8 versus 75.5 ± 43.1; p < 0.004), when compared to the ones without coronary artery disease. The ultrasound revealed greater proximal reference diameter (4.1 ± 0.6 versus 3.7 ± 0.5; p < 0.007), smaller crossed sectional area (4.2±1.6 versus 5.2 ± 1.8; p < 0.02), and the calcification was located in a deeper arterial layer (69 versus 9%; p < 0.004) in patients with chronic kidney disease when compared to the Control Group. CONCLUSION: Lesions of the patients with chronic kidney disease presented a larger proximal diameter and intense calcification in the deeper layer of the vessel, which suggest a greater positive remodeling effect in response to a more aggressive atherosclerotic process in the medial section of the artery.

Conservadorismo e rigidez na política monetária: uma estimativa da função de reação do BCB (2000-2007)

This paper aims at evaluating the conduction of monetary policy after the adoption of inflation targeting. Formation of Selic rate is modeled by estimating a reaction function of the BCB. Results show an excessive degree of interest rate smoothing and a high level of equilibrium interest rate. This evidence supports the belief that Selic rate's formation is ruled by a conservative behavior. The conservative conduction of monetary policy is related to two distinct features of BCB's reaction function: i) the great weight of autoregressive components; and, chiefly, ii) a very high level of the equilibrium interest rate. The main conclusion is that, all remaining unchanged, the interest rate would hardly be reduced in a satisfactory way. Massive and chronic deflation would be needed if Selic were to reach a reasonable level, closer to that of rates in the rest of the world. This evidences the need for a debate on the adequacy of current stabilization strategy.

The Brazilian deindustrialization: financialization is not guilty

The financialization of the Brazilian economy is often criticized as being responsible of the slowdown of capital accumulation in this country. Indeed, very high interest rates are maintained in order to finance the public debt, and this fosters capitalists to get more Treasury bonds rather than to invest in the productive area. Nevertheless, the evolution of the profit rate in this area also explains the particular relation existing between capitalists, finance and productive investment, as Marx showed it more than a century ago.
