Amyloid peptide, the main component of senile plaques, is a major biological characteristic of Alzheimer’s disease (AD). The aim of the present study conducted on human neuronal SK-N-BE cells was to evaluate whether oligomerized Aβ1-40-induced cell damages was associated with lipid modifications. Under treatment with Aβ1-40 (10 100 μM; 24 48 h), cell viability was recorded with the MTT test and...

BACKGROUND Coronary artery disease (CAD) is associated with verbal memory decline, although deterioration may be mitigated in individuals undertaking exercise interventions. Ceramide sphingolipids, suggested to play a role in pathological neurodegeneration, have been associated with the development and progression of CAD but their relationship with cognitive response to exercise has not been as...

BACKGROUND Polyunsaturated n-3 fatty acids have been shown to inhibit the growth and metastasis of tumors. This double-blind, randomized study was designed to evaluate the hypothesis that polyunsaturated n-3 fatty acids can improve metabolic parameters, decrease chemical indices of inflammation, enhance quality of life, and extend disease free interval and survival time for dogs treated for lym...

OBJECTIVES Effect of paraquat on the fatty acid composition (weight percentage) of rat lung was studied with particular reference to the change of hydroxyproline content in the course of paraquat-induced dysfunction and subsequent repair. METHODS Eight-week-old male Wistar rats were administered paraquat at 20 mg/kg body weight subcutaneously, and the wet weight, hydroxyproline content and fa...

Vietnam's sea is assessed to be very diverse and rich in seaweed species. It about 1000 different species of seaweed, which more than 800 have been identified, classify into genus, families, classes, phylums, continuously updated from the 1950s present. Previous studies by Vietnamese international scientists shown that lipids contain many valuable active ingredients such as acids C20: 4n-6 (AA)...

The chemical composition variations of the Indian mackerel (Rastrelliger kanagurta) from Karachi coast were investigated seasonally over the period of one year (2004-2005).  Moisture, crude protein, fat and ash contents varied from 70.11-74.41%, 16.02- 20.09%, 3.0-12%, and 0.89-1.35% respectively. The seasonal data indicated that the main fatty acids of the total lipid were C16:0, C16:1, C18:0,...

We examine the asymptotic behavior of unit root tests against nonlinear alternatives of the exponential smooth transition type if the data is erroneously nonlinearly transformed. We show analytically and by a Monte Carlo study that the probability of rejecting the correct null of a random walk depends heavily on the type of data transformation. JEL-Numbers: C12, C22, F31

This paper assesses the long-run bilateral trade relations between the US and Mexico. North American Free Trade Agreement (NAFTA) had no additional impacts on import functions. Gradual switching existed even before the agreement became effective. © 2002 Society for Policy Modeling. Published by Elsevier Science Inc. All rights reserved. JEL classification: F13; C22
