Biomechanical and biochemical investigation of erythrocytes in late stage human leptospirosis

Braz. j. med. biol. res; 53 (8), 2020
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 ...

Proteínas homólogas de unión a reticulocitos de Plasmodium falciparum involucradas en el proceso de invasión al eritrocito: revisión de la literatura

Introducción: la malaria es uno de los mayores retos de la salud pública mundial. Es causada principalmente por los parásitos Plasmodium falciparum y Plasmodium vivax. Durante el proceso de invasión, se encuentran involucra-das las proteínas homólogas de unión a reticulocitos de P.falciparumPfRH1,...

Immunoproteomics of Plasmodium falciparum-infected red blood cell membrane fractions

Mem. Inst. Oswaldo Cruz; 112 (12), 2017
BACKGROUND The surface of infected red blood cells (iRBCs) has been widely investigated because of the molecular complexity and pathogenesis mechanisms involved. Asymptomatic individuals are important in the field because they can perpetuate transmission as natural reservoirs and present a challenge for ...

Valor diagnóstico de la morfología eritrocitaria en las anemias

A pesar de la disponibilidad de modernos equipos automatizados, el estudio de la morfología eritrocitaria en extendidos de sangre periférica continúa desempeñando un rol fundamental en el diagnóstico de las anemias. En 2005, el Grupo Internacional de Consenso para la Revisión en Hematología public...

In vivo antipyretic, antiemetic, in vitro membrane stabilization, antimicrobial, and cytotoxic activities of different extracts from Spilanthes paniculata leaves

Biol. Res; 47 (), 2014
BACKGROUND: The study was conducted to evaluate the in vitro antimicrobial activity, cytotoxic, and membrane stabilization activities, and in vivo antiemetic and antipyretic potentials of ethanolic extract, n-hexane and ethyl acetate soluble fractions of Spilanthes paniculata leaves for the first time wi...

Aspectos estruturais da membrana eritrocitária
Structural aspects of the erythrocyte membrane

Este artigo descreve as estruturas e funções da membrana eritrocitária e sua importância na medicina transfusional. A membrana eritrocitária é uma das membranas mais conhecidas em termos de estrutura, função e genética. Como qualquer membrana plasmática, tem como função mediar transportes e, ...

Enzymes and membrane proteins of ADSOL-preserved red blood cells

Säo Paulo med. j; 118 (2), 2000
CONTEXT: The preservative solution ADSOL (adenine, dextrose, sorbitol, sodium chloride and mannitol) maintains red cell viability for blood trans-fusion for 6 weeks. It would be useful to know about its preservation qualities over longer periods. OBJECTIVE: To determine some red cell biochemical paramete...
