Desorption electrospray ionization-mass spectrometry (DESI-MS) imaging was used to analyze unmodified human brain tissue sections from 39 subjects sequentially in the positive and negative ionization modes. Acquisition of both MS polarities allowed more complete analysis of the human brain tumor lipidome as some phospholipids ionize preferentially in the positive and others in the negative ion ...

Background: Cardiovascular risk factors have increased along with economic development, but it is not clear if this tendency differs by education. The aim of this study was to analyze the effect of education on blood lipid levels while income increases over a decade in Chilean adults. Methods: A cohort study was conducted from 3092 births in Limache Hospital between 1974 and 1978, of which 998 ...

Lipid monolayer chain melting transitions were simulated using a two-state Doniach model, and experimental melting profiles of lipid vesicles were analyzed. We sampled the information of a Monte Carlo simulation into a single broad histogram containing complete information about the distribution of states. The information of the monolayer histogram was first used to calculate the melting behavi...

background: dyslipidemia is considered an independent risk factor for coronary heart disease (chd). in the present study, we examined lipid profiles and paraoxonase 1 (pon1) activity and atherogenic indexes status and the relationship of pon1 activity by high-density lipoprotein (hdl) and atherogenic indexes in chd patients and healthy people. methods: the aim of the study was to compare pon1, ...

conclusions acute l-carnitine supplementation possibly affects exercise performance and triglycerides in athletes rather than sedentary men. objectives this study aimed to investigate the acute effects of l-carnitine supplementation on aerobic metabolic efficiency and lipid profiles in sedentary and athletic men. methods fifteen sedentary (20.4 ± 1.5 years) and 15 athletic (21.5 ± 2.4 years) me...

There is extensive literature documenting the bioaccumulation of persistent organic pollutants in the marine environment, but relatively little data are available on contamination pathways in aquaculture systems such as that for farmed salmon. In recent years,the salmon industry has grown significantly in Europe. This study reports on the determination of a wide range of polychlorinated bipheny...

INTRODUCTION AND OBJECTIVES Patients at high risk of suffering cardiovascular events require medical treatment to optimize their lipid profile. The present analysis evaluates the lipid profiles among Spanish patients receiving statin therapy in the international DYSIS study. METHODS DYSIS is a multinational cross-sectional study carried out in Canada and Europe (n=22,063). In Spain, 3710 pati...
