Research paper thumbnail of Effect of the AuNPs Biosynthesized Used as Anodes on the Performance of a Human Blood Paper-Based Microfluidic Fuel Cell

AuNPs were evaluated as anodes in paper-based microfluidic fuel cells for the oxidation of glucose in blood. In an innovative way and with the aim of having a more realistic application approach, the devices were tested with two different types of blood: one blood with glucose levels in the normal range and the other with glucose levels in the diabetes range. The power densities obtained for these kinds of blood were 0.54 and 0.85 mW cm-2, respectively.

TEM, SEM, XRD, XPS, and cyclic voltammetry were employed for the Pd/CX100 characterization. The paper-based mFC using Pd/CX100 as anode was evaluated employing 0.1 M and 0.5 M glycerol of each glycerol sample and achieving power densities of 0.242 and 0.160; 0.15 and 0.127; and 0.108 and 0.090 mW cm-2 for reagent grade glycerol, glycerol from sunflower oil biodiesel, and glycerol from used cooking oil biodiesel, respectively.

Journal of Functional Foods, 2018

Animals were fed with high fat and fructose diet (HFF) and supplemented with PR-PJBP and DFR-PJBP for eighteen weeks. PR-PJBP produced the greatest hypoglycemic effect by improving insulin resistance, increasing hepatic glycogen content, and decreasing hepatic PEPCK activity. Likewise, PR-PJBP decreased serum triglycerides levels, ameliorating hepatic steatosis, decreasing hepatic expression of Srebp1 and Fasn, and increasing hepatic Cpt1 expression. These results suggest that polyphenols from PJBP exert a greater beneficial effect on obesity-related complications than dietary fiber. These effects were associated with caffeoylquinic, p-coumaroylquinic and 4feruloylquinic acids, and kaempferol derivatives. PR-PJBP could be used as an ingredient for the elaboration of functional foods.

Research paper thumbnail of Juice by-products as a source of dietary fibre and antioxidants and their effect on hepatic steatosis

In this study, the nutraceutical compounds of mango, guava and peach by-products from the juice industry were characterized. Mango and peach by-products presented an adequate balance of insoluble/soluble dietary fibre, as well as a high content of carotenoids (27.9 and 2.4 mg β-carotene/g, respectively) and polyphenols (102.0 and 83.6 GAE mg/g, respectively). Guava by-product presented the highest content of insoluble dietary fibre (74%). Several phytosterols and saponins were identified in all by-products. Juice by-products decreased the activity of α-amylase, and scavenged DPPH and nitric oxide radicals. An in vivo study was carried out in high fat and fructose (HF/HFr) diet-fed rats. Guava by-product decreased bodyweight gain (8%) and peach and mango by-products reduced hyperglycaemia (~25%). Hepatic steatosis was reduced by all by-products. Juice by-products improved some complications of obesity.
