1. Biomechanical and biochemical investigation of erythrocytes in late stage human leptospirosis
Leptospirosis is a zoonotic disease caused by bacteria of the genus Leptospira, which can cause lipid changes in the erythrocyte membrane. Optical tweezers were used to characterize rheological changes in erythrocytes from patients with leptospirosis in the late stage. Biochemical methods were also used for quantification of plasma lipid, erythrocyte membran

2. Concentration of soybean lecithin affects short-term storage success of goat semen related with seminal plasma removal
Abstract The objective of this study was to investigate the need of seminal plasma removal for short-term cooling of buck semen in soybean lecithin (SL) based extender. Each pool was divided equally, and one half was subjected to centrifugation to remove seminal plasma (SP-), while the other half remained with seminal plasma (SP+). Then, both SP+ and SP- sam

3. Plasma kinetics of an LDL-like nanoemulsion and lipid transfer to HDL in subjects with glucose intolerance
OBJECTIVE: Glucose intolerance is frequently associated with an altered plasma lipid profile and increased cardiovascular disease risk. Nonetheless, lipid metabolism is scarcely studied in normolipidemic glucose-intolerant patients. The aim of this study was to investigate whether important lipid metabolic parameters, such as the kinetics of LDL free and est

4. Simultaneous transfer of cholesterol, triglycerides, and phospholipids to high-density lipoprotein in aging subjects with or without coronary artery disease
OBJECTIVE: To verify whether the capacity of high-density lipoprotein (HDL) to simultaneously receive nonesterified cholesterol, triglycerides, cholesteryl esters, and phospholipids changes with aging and the presence of coronary artery disease. DESIGN: Cross-sectional study with biochemical analyses. SUBJECTS: Eleven elderly patients with coronary artery di

5. Melatonina, isoenzimas de glutationa S-transferases e estresse oxidante em pacu Piaractus mesopotamicus (Holmberg, 1887) / Melatonin, Glutathione S-transferases isoenzymes, and oxidative stress in pacu, Piaractus mesopotamicus (Holmberg, 1887).
Oxygen is vital for vertebrates. However, changes in the levels of dissolved oxygen in water might cause oxidative stress in fishes because the shortage of oxygen followed by reoxygenation originates reactive oxygen species (ROS) inside cells. Higher intracellular levels of ROS favor alterations of proteins, phospholipids and nucleic acid molecules, which re

6. Chronic postnatal administration of methylmalonic acid provokes a decrease of myelin content and ganglioside N-acetylneuramic acid concentration in cerebrum of young rats
Levels of methylmalonic acid (MMA) comparable to those of human methylmalonic acidemia were achieved in blood (2-2.5 mmol/l) and brain (1.35 µmol/g) of rats by administering buffered MMA, pH 7.4, subcutaneously twice a day from the 5th to the 28th day of life. MMA doses ranged from 0.76 to 1.67 µmol/g as a function of animal age. Control rats were treated

7. INFLUENCE DIFFERENT FATTY ACID OF THE DIET ON AN ANIMAL MODEL OF MANIA INDUCED BY AMPHETAMINE IN RATS / INFLUÊNCIA DOS DIFERENTES ÁCIDOS GRAXOS DA DIETA SOBRE UM MODELO ANIMAL DE MANIA INDUZIDO POR ANFETAMINA EM RATOS
Fatty acids (FA) are constituent important of the neuronal phospholipids membranes and they carry out important functions in the development and function of the brain During the last decades changes were observed in the feeding habits of western countries, with an increase of the trans FA and omega-6 (n-6) and detriment of omega-3 fatty acids (n-3) consumpti

8. Perfil lipÃdico e correlaÃÃo entre concentraÃÃo e atividade de Lecitina: colesterol aciltransferase (LCAT) em plasma de pacientes com esquistossomose mansÃnica hepatointestinal e hepatoesplÃnica
Schistosomiasis, a disease caused by helminth Schistosoma mansoni affects about 200 million people worldwide. Due to deposition of eggs of the parasite in the liver, the disease may progress to a more mild, hepatointestinal (HI), for the most severe, hepatosplenic (HS). Previous studies show a relationship between lipid metabolism and the hepatosplenic form

9. Chylomicron metabolism and lipid reception capacity of high density lipoprotein in metabolic syndrome (MetS) and type 2 diabetes mellitus (DM2) / Metabolismo dos quilomícrons e capacidade da lipoproteína de alta densidade (HDL) de receber lípides na síndrome metabólica e no diabetes mellitus tipo 2
The main metabolic disturbances occurring as a result of type 2 diabetes mellitus (DM2) and Metabolic Syndrome (MetS) are alterations in the metabolism of lipids. It is therefore, important to better understand the aspects by which plasma lipoproteins are metabolized. The evaluation of chylomicron metabolism and lipid transfer of high density lipoprotein (HD

10. Efeito do tratamento com novos derivados imidazolidÃnicos e praziquantel sobre os lipÃdios de camudongos infectados por Schistosoma mansoni
The Schistosomiasis mansoni is the second human parasitosis more prevalent in the world, being in Brazil a problem of public health. The schistosomiasis alters lipid metabolism, promoting decrease in plasma levels of total cholesterol (TC), total phospholipids (TF) and triglycerides (TG). The praziquantel (PZQ) is the principal agent schistosomicidal employe

11. Transferência "in vitro" de lípides de uma nanoemulsão artificial para a fração HDL de pacientes com diabetes mellitus tipo 2 / Lipid transfer "in vitro" from an artificial nanoemulsion to the HDL fraction in patients with type 2 diabetes.
Type II diabetes mellitus has become one of the worlds main public health issues. High triglyceride concentrations and low HDL-C concentrations are the main in the plasma lipids found in DM2. Hipertriglyceridemia is but one of the factors that cause lipoprotein composition, which in turn can cause alterations in particle function. The antiatherogenic effect

12. Modifications of the composition of plasma lipoproteins in physically trained young male individuals / Modificações da composição quimica de lipoproteinas plasmaticas em jovens do sexo masculino fisicamente exercitados
Regular physical activity is related to a reduced risk of cardiovascular disease possibly by improvement of the lipoprotein profile. But there are many deficiencies in the current knowledge in this area like at what age this benefit initiate, what is the amount and intensity of the exercises, among others. In this study we evaluated the efficiency of regular
