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.

Assessing Bioenergetic Function in Response to Reactive Oxygen Species in Neural Cells

open access: yes, 2020
In this study, we characterized the bioenergetic response of the Lund human mesencephalic (LUHMES) cell line and a mouse astrocyte cell line to oxidative stress. Extracellular hydrogen peroxide (H2O2) levels and bioenergetic response were investigated in

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

Granzymes in health and diseases: the good, the bad and the ugly

open access: yesFrontiers in Immunology
Granzymes are a family of serine proteases, composed of five human members: GA, B, H, M and K. They were first discovered in the 1980s within cytotoxic granules released during NK cell- and T cell-mediated killing.

A long-term "memory" of HIF induction in response to chronic mild decreased oxygen after oxygen normalization [PDF]

open access: yes, 2007
Background Endothelial dysfunction (ED) is functionally characterized by decreased vasorelaxation, increased thrombosis, increased inflammation, and altered angiogenic potential, has been intimately associated with the progression and severity of ...

Reactive Oxygen Species

open access: yes, 2021
AbstractToday, many factors such as advancing technology, environmental pollution,radiation, contaminated water, pesticides, heavy metals, stress and oxygen metabolismin living cells inevitably cause the formation of free radicals in the human body.Free radicals are very reactive forms of oxygen that destroy the cells of the organism.This calls for ...

Oxygen Radicals and Reactive Oxygen Species in Reproduction

open access: yesExperimental Biology and Medicine, 1991
Free radicals and reactive oxygen species play a number of significant and diverse roles in reproductive biology. In common with other biological systems, mechanisms have evolved to minimize the damaging effects that these highly reactive molecules can have on reproductive integrity.
