Lipoprotein(a) induces glomerular superoxide anion production [PDF]
Nephrology Dialysis Transplantation, 1997 Lipoprotein(a) (Lp(a)) is considered to accelerate glomerular injury in various forms of renal disease. Several tissue culture studies suggested that biological effects of Lp(a) are inhibitable by oxygen radical scavengers. Since reactive oxygen metabolites (ROM) are important mediators of renal disease, we studied the effects of native and oxidized Lp(

Endothelin-1 in paraventricular nucleus modulates cardiac sympathetic afferent reflex and sympathetic activity in rats. [PDF]
PLoS ONE, 2012 Cardiac sympathetic afferent reflex (CSAR) is a positive-feedback, sympathoexcitatory reflex. Paraventricular nucleus (PVN) is an important component of the central neurocircuitry of the CSAR. The present study is designed to determine whether endothelin-

Oxidative stress and disruption of the antioxidant defense system as triggers of diseases
Regulatory Mechanisms in Biosystems, 2023 Oxidative stress is a state when the content of free radicals in a living organism is excessive. Molecules of free radical nature start a chain reaction that disrupts the integrity of cells, leading to their damage or death.
