Prevalencia del anticuerpo anti receptor de fosfolipasa A2 sérico e histológico en pacientes con nefropatía membranosa en un Centro Universitario

Rev. méd. Chile; 149 (1), 2021
BACKGROUND: The discovery of the phospholipase A2 receptor antigen and its highly specific autoantibody (anti-PLA2R Ab) was useful for the diagnosis and follow-up of patients with membranous nephropathy (MN). Thus, some international guidelines recommend not performing renal biopsy in patients with posit...

A rare case of PLA2R- and THSD7A-positive idiopathic membranous nephropathy

J. bras. nefrol; 42 (2), 2020
ABSTRACT Idiopathic membranous nephropathy (IMN) is a frequent cause of nephrotic syndrome in adults. In terms of etiology, the condition may be categorized as primary/idiopathic or secondary. Literature on the pathophysiology of IMN has indicated the presence of autoantibodies (PLA2R and THSD7A) directe...

Biochemical characterization of a phospholipase A2 homologue from the venom of the social wasp Polybia occidentalis

Wasp venoms constitute a molecular reservoir of new pharmacological substances such as peptides and proteins, biological property holders, many of which are yet to be identified. Exploring these sources may lead to the discovery of molecules hitherto unknown. This study describes, for the first time in h...

Efficacy of tannins from Mimosa pudica and tannic acid in neutralizing cobra (Naja kaouthia) venom

In the present study, the effectiveness of Mimosa pudica tannins (MPT) in neutralizing the lethality of Naja kaouthia venom was compared with commercially derived tannins. Preincubation of MPT with N. kaouthia venom maintained 100 percent survival of mice after 24 hours. The mouse group in which there wa...

Factores circulantes de injuria endotelial y procesos subendoteliales en mujeres postmenopáusicas sanas

La concentración elevada de lipoproteínas aterogénicas con apo B en mujeres posmenopáusicas (MPM), es un componente importante del mecanismo multifactorial causante de la enfermedad coronaria. En MPM sanas (n=30) en comparación con premenopáusicas (MpreM) (n=28), se evaluó el perfil lipoproteico i...
