Purpose: We have previously demonstrated anti-inflammatory and antioxidant effects of exenatide. We have now hypothesized that exenatide also increases the plasma concentration of IL-1RA, an endogenous anti-inflammatory protein and modulates the Nrf-2-Keap-1-ARE system to induce key antioxidant enzymes to suppress inflammatory and oxidative stress. Methods: Twenty four obese type 2 diabetic patients on combined oral and insulin therapy were randomized to receive either exenatide 10μg or placebo b...

OBJECTIVES: Lung ischaemia-reperfusion injury is a complex pathophysiological process due to the production of reactive oxygen species and the generation of inflammatory reaction. We investigated the protective effects and the corresponding mechanism of melatonin (MT), a potent free-radical scavenger, on lung injury induced by ischaemia-reperfusion in a mouse model. METHODS: Adult male C57BL/6J mice (n = 30) were randomly and equally allocated into 5 groups: sham controls, IR, IR + 10 mg/kg MT, IR + 20 mg/kg MT and IR + 30 mg/kg MT...

Lentil, generally known as poor man's' meat due to its high protein value is also a good source of dietary fiber, antioxidants and vitamins along with fast cooking characteristics. It could be used globally as a staple food crop to eradicate hidden hunger, if this nutritionally rich crop is further enriched with essential minerals. This requires identification of essential mineral rich germplasm. So, in the present study, a core set of 96 wild accessions extracted from 405 global wild annual collections comprising different species was analyzed to determine its bio-fortification potential...

BACKGROUND: Anesthetics in ventilated patients are critical as any cofactor hampering diaphragmatic function may have a negative impact on the weaning progress and therefore on patients' mortality. Dexmedetomidine may display antioxidant and antiproteolytic properties, but it also reduced glucose uptake by the muscle, which may impair diaphragm force production. This study tested the hypothesis that dexmedetomidine could inhibit ventilator-induced diaphragmatic dysfunction. METHODS: Twenty-four rats were separated into three groups (n = 8/group)...

BACKGROUND: Ovalbumin (OVA), a protein with excellent nutritional and processing properties, is the major allergen of hen egg white. Previous study showed that high-intensity ultrasound treatment increased the IgG and IgE binding abilities by unfolding the conformational structure of OVA. It may allow modifying the IgG and IgE binding of OVA by combining high-intensity ultrasound with other methods, such as glycation, a promising method for the improvement of protein properties. RESULTS: Glycation with mannose (M) after ultrasound pretreatment at 0-600 W significantly reduced the IgG and IgE binding abilities and dramatically enhanced the antioxidant activity of OVA-M conjugates, with the lowest values of IgG and IgE binding and highest values of antioxidant capacity observed at 600W...

The production of reactive oxygen species (ROS) is a common phenomenon in podocyte impairment, which leads to the irreversible progression of chronic kidney diseases, such as diabetic kidney disease (DKD). Previous research has indicated that peroxisome proliferator‑activated receptor γ (PPARγ) coactivator‑1α (PGC‑1α) participates in mitochondrial biogenesis and energy metabolism in certain mitochondria‑enriched cells, including myocardial and skeletal muscle cells. Therefore, we hypothesized that PGC‑1α may be a protective nuclear factor against energy and oxidative stress in DKD...
