NADPH oxidase 4 and its role in the cardiovascular system
Vascular Biology, 2019 The heart relies on complex mechanisms that provide adequate myocardial oxygen supply in order to maintain its contractile function. At the cellular level, oxygen undergoes one electron reduction to superoxide through the action of different types of ...

Protective actions of des-acylated ghrelin on brain injury and blood-brain barrier disruption after stroke in mice [PDF]
, 2016 The major ghrelin forms, acylated ghrelin and des-acylated ghrelin, are novel gastrointestinal hormones. Moreover, emerging evidence indicates that these peptides may have other functions including neuro- and vaso-protection.

Nox2 dependent redox-regulation of microglial response to amyloid-β stimulation and microgliosis in aging [PDF]
, 2020 Microglia express constitutively a Nox2 enzyme that is involved in neuroinflammation by the generation of reactive oxygen species (ROS). Amyloid β (Aβ) plays a crucial role in Alzheimer’s disease.

NADPH Oxidases Act as Key Enzyme on Germination and Seedling Growth in Barley (Hordeum vulgare L.)
Plant Production Science, 2010 Reactive oxygen species (ROS) play an important role in seed germination. Although hydrogen peroxide (H2O2), a type of ROS, enhances the germination rate of various plant seeds, little is known about the mechanism.

Perivascular adipose tissue inflammation in vascular disease [PDF]
, 2017 Perivascular adipose tissue (PVAT) plays a critical role in the pathogenesis of cardiovascular disease. In vascular pathologies, perivascular adipose tissue increases in volume and becomes dysfunctional, with altered cellular composition and molecular ...

Effects of Angiotensin II on the Cerebral Circulation: Role of Oxidative Stress
Frontiers in Physiology, 2013 Oxidative stress has emerged as a key component of many diseases that affect the vasculature. Oxidative stress is characterized as a cellular environment where the generation of oxidant molecules overwhelms endogenous antioxidant defense mechanisms ...

Ragweed subpollen particles of respirable size activate human dendritic cells [PDF]
, 2017 Ragweed (Ambrosia artemisiifolia) pollen grains, which are generally considered too large to reach the lower respiratory tract, release subpollen particles (SPPs) of respirable size upon hydration.
