Localized TRPA1 channel Ca2+ signals stimulated by reactive oxygen species promote cerebral artery dilation

Science Signaling, 2015
Peroxidized lipid metabolites trigger calcium influx through the channel TRPA1 to dilate cerebral arteries. Blood Vessel Dilation with Peroxidized Lipids Cerebral arteries must maintain constant blood flow to the brain even though blood pressure ...

Evaluating Non Enzymatic Antioxidants as Potential Biomarkers for Oxidative Stress in Schizophrenia: A Cross-sectional Study

Journal of Clinical and Diagnostic Research
Introduction: Schizophrenia significantly impacts patients and their families. Oxidative stress is implicated in various neurological disorders, including schizophrenia. By studying the levels of antioxidants and oxidative stress markers in schizophrenic

Levels of plasma malondialdehyde and the severity of acne vulgaris

Minia Journal of Medical Research
Comedones, papules, pustules are the hallmarks of acne vulgaris(AV).The pathophysiology of AV involves oxidative stress.Lipid peroxides(LPO), in particular, are reactive oxygen species (ROS) that mediate acne inflammation.

The effect of modulating platelet reactive oxygen species by the addition of antioxidants to prevent clearance of cold-stored platelets

Hematology, Transfusion and Cell Therapy
Background: It is known that the rapid clearance of cold-stored platelets is attributed to various storage lesions, including an abnormal increase in reactive oxygen species when platelets are exposed to cold temperatures.

Oxidative stress: fundamentals and advances in quantification techniques

Frontiers in Chemistry
Oxidative species, generated endogenously via metabolism or from exogenous sources, play crucial roles in the body. At low levels, these species support immune functions by participating in phagocytosis. They also aid in cellular signaling and contribute

Metformin attenuates cuprizone-induced mitochondrial dysfunction and senescence-associated changes in primary neuronal cells

Cell Structure and Function
Mitochondrial dysfunction and cellular senescence are key features of brain aging and neurodegenerative diseases. Cuprizone (CPZ), a mitochondrial toxin, induces oxidative stress, abnormal lipid metabolism, and iron accumulation in neurons and ...

Correlation of Lipid Peroxidation with Glycated Haemoglobin Levels in Diabetes Mellitus

Online Journal of Health & Allied Sciences, 2011
Reactive oxygen species are crucial to normal biological processes; they are potentially dangerous and are commonly referred to as prooxidants. The reactive oxygen intermediates can cause direct cellular injury by including lipid and protein peroxidation

Influence of Free Radicals in the Origin of Atherosclerosis

Revista Finlay, 2020
Most of the pathologic components of oxidative stress of cardiovascular diseases are closely related with diregulation of metabolism of reactive species of oxygen, which favor the appearance of the so called oxidative stress. The oxidation of low density

Effect of cisplatin on lipid peroxidation in the whole blood and plasma of female rats

European Pharmaceutical Journal
Cisplatin is known to induce oxidative stress and accumulation of reactive oxygen species (ROS), which are the primary causes of its undesirable side effects. Lipids are a major target of ROS undergoing oxidation upon interaction.
