1. Estudo das propriedades eletricas das hemacias utilizando pinça optica / Study of electrical properties of red blood cell using optical tweezers
The red blood cell (RBC) membrane contains proteins and glycoproteins embedded in a fluid lipid bilayer that confers viscoelastic behavior. Sialylated glycoproteins of the RBC membrane are responsible for a negatively charged surface, which creates a repulsive electric zeta potential (Z) between the cells.The compact layer of charge or Stern consists of ions

2. FONTES DE ÃLEOS DA DIETA NA COMPOSIÃÃO DO MÃSCULO, LIPOPROTEÃNAS PLASMÃTICAS, IMUNIDADE INATA E RESISTÃNCIA DE TILÃPIAS DO NILO (Oreochromis niloticus L. 1757) / Dietary oil sources in muscle composition, plasmatic lipoprotein, innate immunity and resistance of Nile tilapia (Oreochromis niloticus L. 1757)
The objetive of this study to determine the influence of some dietary fatty acids sources on the chemistry composition, fatty acids profile and total cholesterol in muscle; in cholesterol quantity, triglycerides and plasmatic lipoprotein; in some innate immunity functions; in hematopoiesis; and, in resistence of the Nile tilapia (Oreochromis niloticus L.) to

3. AVALIAÇÃO DE INDICADORES DO ESTRESSE OXIDATIVO E DA ATIVIDADE DA ENZIMA ACETILCOLINESTERASE SANGÜÍNEA EM PACIENTES COM DIAGNÓSTICO DE ACIDENTE VASCULAR CEREBRAL ISQUÊMICO / AVALIATION OF MARKERS OF OXIDATIVE STRESS AND OF ENZYME ACETYLCHOLINESTERASE IN WHOLE BLOOD FROM PATIENTS DIAGNOSED WITH ISCHEMIC STROKE
In ischemic stroke, damage to the brain is caused by a reduction or complete blockage of blood flow to parts of the brain, resulting in glucose and oxygen deficiency. It is a leading cause of mortality and disability particularly in the elderly. The majority of strokes are not fatal and survivors are at a high risk of subsequent vascular complications and ne

4. PurificaÃÃo parcial de uma lectina da raiz de Guettarda platypoda
Lectins, proteins or glycoproteins that reversible bind carbohydrates with distinct degrees of selectivity, they are found in a variety of organisms being involved in numerous cellular processes. In this work evaluated the presence of lectin(s) from Guettarda platypoda D.C., plant popular know with âangelicaâ. Roots of this plant have been used in folk med

5. Purificação, caracterização bioquimica e funcional de uma serinoprotease (Uruprot) do veneno de Bothrops alternatus (Urutu)
Snake venoms contain a high variety of toxic compounds and enzymes. Venom purified proteases are structurally dassified as serine proteases and metalloproteases, and showa potent effect on blood coagulation, acting on hemostasis, thrombosis, fibrinolysis and platelet aggregation. The aim of this work was the purification and characterization of a serine prot

6. Adaptações induzidas pelo treinamento fisico no metabolismo oxidativo e sistema de defesa antioxidante em musculo e sangue de ratos e sua correlação com os níveis de leão muscular
Physical training is known to induce a large number of adaptations in whole body. One of the most studied is the increase in musle oxidative metabolism, mainly because the rise in Krebs cycle, ?-oxidation of fatty acids and electron transport chain enzymes. Although, exercise can increase free radicaIs generation too) and if the cells are not able to detoxii

7. Purificação e caracterização de enterohemolisina produzida por Escherichia coli enteropatogenicas
Enterohaemolysins (EHly) were ftrst detected in classical enteropathogenic Escherichia coZi strains (EPEC), isolated from feces of infants with diarrhea, and also detected in strains isolated from animaIs. Differring from a-haemolysin, EHly is not spontaneously released to culture medium. Sonication was the most efficient method to extract EHly. In order to
