Oxidative stress, telomere length, and frailty in an old age population

Rev. invest. clín; 71 (6), 2019
Abstract Background A global aging population requires focusing on the risk factors for unhealthy aging, preventive medicine, and chronic disease management. The identification of adverse health outcomes in older adults has been addressed by the characterization of frailty as a biological syndrome. In t...

The effects of remifentanil used during cesarean section on oxidative stress markers in correlation with maternal hemodynamics and neonatal outcome: a randomized controlled trial

Rev. bras. anestesiol; 69 (6), 2019
Abstract Background and objective: Remifentanil is used to attenuate maternal hemodynamic response to intubation and surgical stress during Induction-Delivery period of cesarean section. The goal was to compare the effects of two remifentanil dosing regimens on oxidative stress level, in correlation wit...

Inhibition of paracetamol-induced acute kidney damage in rats using a combination of resveratrol and quercetin

Int. j. morphol; 37 (4), 2019
Paracetamol (also called acetaminophen, or APAP) overdose causes acute damage to the liver and kidneys in both humans and experimental animal models via the induction of the oxidative stress pathway. We sought to determine whether the combined antioxidants and anti-inflammatory compounds, resveratrol (RE...

Nrf2, NF-κB and PPARβ/δ mRNA Expression Profile in Patients with Coronary Artery Disease

Arq. bras. cardiol; 113 (6), 2019
Abstract Background: Oxidative stress and inflammation are present in coronary artery disease (CAD) and are linked to the activation of the transcription nuclear factor kappa B (NF-κB). To attenuate these complications, transcription factors like nuclear factor erythroid 2-related factor 2 (Nrf2) a...

Functional iron deficiency in patients on hemodialysis: prevalence, nutritional assessment, and biomarkers of oxidative stress and inflammation

J. bras. nefrol; 41 (4), 2019
Abstract Introduction: Anemic patients with chronic kidney disease (CKD) can be divided into anemic patients without or with functional iron deficiency (FID). The increase in the number of cases of hemosiderosis in patients on hemodialysis (HD) attributed to excessive intravenous iron replacement has ca...

El factor de transcripción bZIP Afap1 afecta al estrés oxidativo y la biosíntesis de aflatoxinas en Aspergillus flavus
The bZIP transcription factor Afap1 mediates the oxidative stress response and aflatoxin biosynthesis in Aspergillus flavus

Rev. argent. microbiol; 51 (4), 2019
Abstract Aflatoxin is a carcinogenic secondary metabolite produced mainly by Aspergillus flavus and Aspergillus parasiticus, which can seriously endanger the health of humans and animals. Oxidative stress is a common defense response, and it is known that reactive oxygen species (ROS) can induce the synt...

Efecto de la cáscara o pulpa de Solanum Tuberosum sobre el peso de órganos y estrés oxidativo hepático en ratas obesas

RESUMEN Con el objetivo de determinar el efecto del consumo de harina de cáscara o harina de pulpa de dos variedades de Solanum tuberosum (papa Yungay y papa Canchán) sobre la acumulación de tejido adiposo, peso de órganos y estrés oxidativo en hígado de ratas realizamos un estudio experimental en ...

Environmental Enrichment Promotes Antioxidant Effect in the Ventrolateral Medulla and Kidney of Renovascular Hypertensive Rats

Arq. bras. cardiol; 113 (5), 2019
Abstract Background: Arterial hypertension is a precursor to the development of heart and renal failure, furthermore is associated with elevated oxidative markers. Environmental enrichment of rodents increases performance in memory tasks, also appears to exert an antioxidant effect in the hippocampus of...
