Hypothesis : soluble Aβ oligomers in association with redox-active metal ions are the optimal generators of reactive oxygen species in Alzheimer's disease [PDF]

open access: yes, 2010
Considerable evidence points to oxidative stress in the brain as an important event in the early stages of Alzheimer's disease (AD). The transition metal ions of Cu, Fe, and Zn are all enriched in the amyloid cores of senile plaques in AD.

Reactive oxygen species and cellular oxygen sensing [PDF]

open access: yesFree Radical Biology and Medicine, 2007
Many organisms activate adaptive transcriptional programs to help them cope with decreased oxygen (O(2)) levels, or hypoxia, in their environment. These responses are triggered by various O(2) sensing systems in bacteria, yeast and metazoans. In metazoans, the hypoxia inducible factors (HIFs) mediate the adaptive transcriptional response to hypoxia by ...

The phosphoinositide 3-kinase-dependent activation of Btk is required for optimal eicosanoid production and generation of reactive oxygen species in antigen-stimulated mast cells [PDF]

open access: yes, 2008
Activated mast cells are a major source of the eicosanoids PGD(2) and leukotriene C(4) (LTC(4)), which contribute to allergic responses. These eicosanoids are produced following the ERK1/2-dependent activation of cytosolic phospholipase A(2), thus ...

Interplay of catalyst corrosion and homogeneous reactive oxygen species in electrochemical ozone production [PDF]

open access: yes, 2023
Electrochemical ozone production (EOP), a six-electron water oxidation, offers potentially sustainable routes for value-added oxidations and disinfectants, but progress in this field is slowed by a dearth in understanding fundamental mechanisms and how ...

Reactive oxygen species and redox signaling in breast cancer [PDF]

open access: yes, 2017
Breast cancer progression depends on host innate and adaptive immune responses. Despite the effect of immune system in tumor destruction, cancer cells may induce the immune cells to support tumor progression.

Plasma reactive oxygen species levels are correlated with severity of age-related hearing impairment in humans [PDF]

open access: yes, 2014
To investigate the relationship between plasma reactive oxygen species (ROS) levels and severity of age-related hearing impairment in humans. We recruited 302 adult subjects aged 40-77 years with normal or symmetrical sensorineural hearing loss.

Reactive Oxygen Species [PDF]

open access: yesArteriosclerosis, Thrombosis, and Vascular Biology, 2004
Platelets participate not only in thrombus formation but also in the regulation of vessel tone, the development of atherosclerosis, angiogenesis, and in neointima formation after vessel wall injury. It is not surprising, therefore, that the platelet activation cascade (including receptor-mediated tethering to the endothelium, rolling, firm
