Estudo da morfologia e status oxidativo em rim de ratos com nefropatia isquêmica após tratamento com células-tronco mesenquimais de tecido adiposo

A nefropatia isquêmica é uma doença renal crônica provocada pela redução do fluxo sanguíneo renal que pode progredir para a doença renal terminal, cujo tratamentos disponíveis se baseiam em terapias substitutivas da função renal, como diálise ou transplante renal. No entanto, devido ao alto c...

Reduction of oxidative stress improves insulin signaling in cardiac tissue of obese mice

ABSTRACT Objective To evaluate the effects of oxidative stress on insulin signaling in cardiac tissue of obese mice. Methods Thirty Swiss mice were equally divided (n=10) into three groups: Control Group, Obese Group, and Obese Group Treated with N-acetylcysteine. After obesity and insulin resistance w...

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...

Evaluation of redox profiles in exogenous subclinical hyperthyroidism at two different levels of TSH suppression

ABSTRACT Objective: Evaluate the relationship between exogenous subclinical hyperthyroidism and oxidative stress through the analysis of the redox profile of patients with subclinical hyperthyroidism exogenous (SCH) grade I (TSH = 0.1 to 0.4 IU/mL) and grade II (TSH < 0.1 IU/mL). Subjects and method...

An experimental study on the preventive effects of N-acetyl cysteine and ozone treatment against contrast-induced nephropathy

Acta cir. bras; 33 (6), 2018
Abstract Purpose: To compare the preventive effects of N-acetyl cysteine (NAC), ozone preconditioning and ozone treatment against contrast-induced nephropathy (CIN) in an experimental rat model. Methods: Thirty adult male Wistar rats were randomly distributed into five groups (n=6 for each group). Gro...

Treatment of experimental periodontal disease by laser therapy in simvastatin-modified rats

J. appl. oral sci; 25 (4), 2017
Abstract Low intensity laser can be used as a promising alternative in the treatment of periodontal disease. Objective The aim of this study was to evaluate low-level laser therapy (LLLT) as an adjuvant treatment for scaling and root planing (SRP) for the treatment of induced periodontitis in simvastat...

Obesity, bariatric surgery and oxidative stress

Summary Introduction: Obesity refers to the accumulation of fatty tissues and it favors the occurrence of oxidative stress. Alternatives that can contribute to body weight reduction have been investigated in order to reduce the production of reactive oxygen species responsible for tissue damage. The ai...

Protein carbonyl content: a novel biomarker for aging in HIV/AIDS patients

Braz. j. infect. dis; 21 (1), 2017
Abstract Background: The major complications of “treated” Human Immunodeficiency Virus (HIV) infection are cardiovascular disease, malignancy, renal disease, liver disease, bone disease, and perhaps neurological complications, which are phenomena of the normal aging process occurring at an e...

Gingival crevicular fluid oxidative stress level in patients with periodontal disease and hyperlipidemia

Abstract: This study aimed to assess the impact of hyperlipidemia on healthy and diseased periodontal tissue by evaluating oxidative stress biomarkers in gingival crevicular fluid (GCF). Clinical periodontal parameters and blood serum lipid, GCF malondialdehyde (MDA), protein carbonyl (PC), and total ant...
