INTRODUCTION: Ca2+ spark constitutes the elementary units of cardiac excitation-contraction (E-C) coupling in mature cardiomyocytes.Human induced pluripotent stem cell (hiPSC)-derived cardiomyocytes are known to have electrophysiological properties similar to mature adult cardiomyocytes.However, it is unclear if they share similar calcium handling
Foram estudados os sistemas reprodutivos de Inga edulis Mart.e Inga stipularis D.C.em uma área de floresta, localizada na Fazenda Experimental da UFAM, Manaus, AM, entre novembro/2006 a novembro/2007.Os resultados mostraram que as espécies não formam frutos a partir de autopolinizações e que o percentual de frutos provenientes de polinizaçõe
Diabetes mellitus is a key cause of chronic kidney disease (CKD) in developed contries.Disorders of glucose metabolism regulation in CKD are explained by insulin resistance, decreased insulin clearance, weak hormonal response to hypoglycemia.These disturbances appear in inhibition of glomerular filtration rate under 60 ml/min.Hemodialysis treatment
The safe operation of high-power solid-state transformers (SSTs) in medium-voltage grid-connected applications relies on medium-frequency transformers (MFTs).In MFTs, hybrid foil-litz windings present a cost-effective alternative to litz wire, since foil is employed as the main conductor.This innovative topology exhibits lower ohmic losses than con
Embedding nanostructures within a bulk matrix is an important practical approach towards the electronic engineering of high performance thermoelectric systems.For power generation applications, it ideally combines the efficiency benefit offered by low dimensional systems along with the high power output advantage offered by bulk systems.In this wor
