Abstract The accumulation of heavy metals and of pesticides in the soil have a negative impact on Capsicum chinense var. Aji Mochero and Capsicum baccatum var. pendulum Bishop's Crown species, the present work highlighting the exerted influence on the superoxid-dismutase activity, catalase and peroxidase...

Comparing the effects of vitamin E tocotrienol-rich fraction supplementation and α-tocopherol supplementation on gene expression in healthy older adults

Clinics; 74 (), 2019
OBJECTIVES This study aims to compare the differential gene expression resulting from tocotrienol-rich fraction and α-tocopherol supplementation in healthy older adults. METHODS A total of 71 eligible subjects aged 50 to 55 years from Gombak and Kuala Lumpur, Malaysia, were divided into three gro...

LBP reduces theinflammatory injuryof kidney in septic rat and regulates the Keap1-Nrf2∕ARE signaling pathway

Acta cir. bras; 34 (1), 2019
Abstract Purpose: To investigate the influence of lycium barbarum polysaccharides (LBP), a functional derivative from lycium barbarum, on septic kidney injury. Methods: The SD male rats were randomly divided into 8 groups. The concentration of IL-1β, IL-6, IL-8, TNF-α, NF-κB and ROS, in...

An experimental study of exenatide effects on renal injury in diabetic rats

Acta cir. bras; 34 (1), 2019
Abstract Purpose: To investigate the effects of exenatide on renal injury in streptozotocin-induced diabetic rats. Methods: Fifty SD rats were randomly divided into normal control, model, exenatide-1, exenatide-2 and exenatide-3 groups, 10 rats in each group. The diabetic nephropathy model was constr...

Protective roles of Pyracantha fortuneana extract on acute renal toxicity induced by cadmium chloride in rats

Acta cir. bras; 34 (7), 2019
Abstract Purpose: To investigate the protective roles of pyracantha fortune fruit extract (PFE) on acute renal toxicity induced by cadmium chloride (CdCl2) in rats. Methods: Rats were pretreated with PFE and consecutively injected with CdCl2 (6.5 mg/kg) for 5 days. Results: The concentration of Cd, ki...

Splenic ischemic preconditioning attenuates oxidative stress induced by hepatic ischemia-reperfusion in rats

Acta cir. bras; 34 (7), 2019
Abstract Purpose: To evaluate the effects of splenic ischemic preconditioning (sIPC) on oxidative stress induced by hepatic ischemia-reperfusion in rats. Methods: Fifteen male Wistar rats were equally divided into 3 groups: SHAM, IRI and sIPC. Animals from IRI group were subjected to 45 minutes of part...

Water pH and hardness alter ATPases and oxidative stress in the gills and kidney of pacu ( Piaractus mesopotamicus )

Neotrop. ichthyol; 17 (4), 2019
This study aimed to assess the effects of low and high water hardness in interaction with different water pH in pacu (Piaractus mesopotamicus). Pacu juveniles were subjected to low (50 mg CaCO3 L-1 - LWH) or high water hardness (120 mg CaCO3 L-1 - HWH) at water pH of 5.5 (acidic), 7.5 (circumneutral) or ...

Effect of ethanol Adiantum capillus-veneris extract in experimental models of anxiety and depression

Depression is one of the most common psychiatric disorders with a prevalence of 15%-25%. Monoamine aminotransferases, in particular, norepinephrine, serotonin, and dopamine, change in the brain of depressed people. Adiantum capillus-veneris is one of the species of the maidenhair fern genus that have tra...

Beta-glucan attenuates cerebral ischemia/reperfusion-induced neuronal injury in a C57BL/J6 mouse model

Beta-glucans (βg), that have many useful effects on human health, are natural polysaccharides. Our aim in this study was to determine useful effect of βg against oxidative and neuronal damage caused by global cerebral ischemia/reperfusion (IR) in stroke imitated mice via surgical operation. A total of ...

Twice-weekly exercise training reduces oxidative stress and proinflammatory cytokine levels in elder women

Motriz (Online); 25 (3), 2019
Aim: Reactive oxygen species and high concentrations of proinflammatory cytokines are related to diseases that are often triggered during the aging process. This study aimed to investigate the effect of moderate-intensity physical exercise, twice a week, on oxidative stress and inflammation biomarkers. ...
