Reactive oxygen species in periodontitis
Journal of Indian Society of Periodontology, 2013 Recent epidemiological studies reveal that more than two-third of the world′s population suffers from one of the chronic forms of periodontal disease. The primary etiological agent of this inflammatory disease is a polymicrobial complex, predominantly ...

Mitochondrial Management of Reactive Oxygen Species [PDF]
Antioxidants, 2021 Mitochondria in aerobic eukaryotic cells are both the site of energy production and the formation of harmful species, such as radicals and other reactive oxygen species, known as ROS.

Reactive oxygen species in status epilepticus
Epilepsia Open, 2023 It has long been recognized that status epilepticus can cause considerable neuronal damage, and this has become one of its defining features. The mechanisms underlying this damage are less clear.

Effects of reactive oxygen species on skin photoaging [PDF]
Przegląd Dermatologiczny, 2016 The large surface area of the skin, high metabolism and location at the border of two environments (external and internal) cause continuous production of free radicals within the skin. There are two mechanisms of skin photoaging.

, 2019 Reactive oxygen species (ROS) are small unstable, highly reactive molecules with a short half-life derived by reduction of molecular oxygen. Once generated, ROS influence signalling molecules, in part through post-translational oxidative modification of proteins, modulating cellular function.

Reactive Oxygen Species: Beyond Their Reactive Behavior [PDF]
Neurochemical Research, 2021 AbstractCellular homeostasis plays a critical role in how an organism will develop and age. Disruption of this fragile equilibrium is often associated with health degradation and ultimately, death. Reactive oxygen species (ROS) have been closely associated with health decline and neurological disorders, such as Alzheimer’s disease or Parkinson’s ...

Mitochondria and Reactive Oxygen Species [PDF]
Hypertension, 2009 Fascination by the mitochondria, “the colonial posterity of migrant prokaryocytes, probably primitive bacteria that swam into ancestral precursors of our eukaryotic cells and stayed there,”1 stems from the above-mentioned nebulous endosymbiotic theory of their origin, as well as from the growing realization of a very special role that they play in the ...

Reactive oxygen species and organellar signaling [PDF]
Journal of Experimental Botany, 2021 Abstract The evolution of photosynthesis and its associated metabolic pathways has been crucial to the successful establishment of plants, but has also challenged plant cells in the form of production of reactive oxygen species (ROS).

Assessing Bioenergetic Function in Response to Reactive Oxygen Species in Neural Cells [PDF]
, 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
