“…The capacity of the non-enzymatic antioxidant defence system in the organs was determined by analysing T-AOC activity. In addition, MDA, one of the toxic aldehyde compounds created by lipid peroxidation, is considered the most important oxide derivative generated during lipid metabolism, and LPO is the product of reaction between oxygen radicals and polyunsaturated fatty acids 40, 41 . Hence, the formation of MDA and LPO in the liver is thought to be the main cause of liver damage 42 .…”

In this study, native depolymerised-exopolysaccharides (DEPS) were successfully derived from the exopolysaccharides (EPS) of Termitomyces albuminosus, and its hepatoprotective effects against a high-fat emulsion and in vitro antioxidant activities were investigated. Based on the results of in vitro assays, DEPS showed superior antioxidant activities compared with EPS dose-dependently. According to the in vivo assays both EPS and DEPS significantly decreased the lipid levels, improved the enzymatic activities, and reduced lipid peroxidation in both serum and hepatic homogenates. Furthermore, EPS and DEPS attenuated the high-fat emulsion-induced histopathological injury to the liver. Both EPS and DEPS might be used as natural drugs to treat and protect against hyperlipidaemia and liver injury induced by a high-fat emulsion. In addition, based on the results of GC and HPLC analyses, rhamnose and low molecular weight compounds may play an important role in contributing to the antioxidant activities of EPS and DEPS.

Unraveling the interactions between cold atmospheric plasma and skin-components with vibrational microspectroscopy

et al. 2015

Using infrared and Raman microspectroscopy, the authors examined the interaction of cold atmospheric plasma with the skin's built-in protective cushion, the outermost skin layer stratum corneum. Following a spectroscopic analysis, the authors could identify four prominent chemical alterations caused by plasma treatment: (1) oxidation of disulfide bonds in keratin leading to a generation of cysteic acid; (2) formation of organic nitrates as well as (3) of new carbonyl groups like ketones, aldehydes and acids; and (4) reduction of double bonds in the lipid matter lanolin, which resembles human sebum. The authors suggest that these generated acidic and NO-containing functional groups are the source of an antibacterial and regenerative environment at the treatment location of the stratum corneum. Based upon the author's results, the authors propose a mechanistic view of how cold atmospheric plasmas could modulate the skin chemistry to produce positive long-term effects on wound healing: briefly, cold atmospheric plasmas have the potential to transform the skin itself into a therapeutic resource.

“…FTIR spectroscopy, as a simple and rapid technique, is playing an increasingly important role in the analysis of edible oils (Van De Voort et al, 2001). The bands of interest are absorption peaks at 3600-2800 and 1800-700 cm -1 (Henna Lu and Tan, 2009).…”

The objective of this study was to determine the effect of different irrigation intervals (every 7 and every 14 days) and fertilizers (farmyard manure, pellet granules and urea) on the composition of safflower seed and its oil stability. Fertilizers have a significant effect on the carbohydrate, fat, ash and protein contents of safflower seed oil. Pellet granules slightly increased the carbohydrate content, while farmyard manure increased the fat and oil contents of safflower seed oil. On the other hand, urea and farmyard manure increased the fibre content compared with pellets, which slightly decreased it. Irrigation every 7 days increased the protein content. Farmyard manure significantly (P < 0.05) increased the mineral content (iron, potassium and calcium). The use of FTIR spectroscopy revealed that the period of storage significantly (P < 0.05) affects oil stability. The peak intensities (absorbencies) recorded for oil stored at zero time changed after storage for 1, 2 and 3 days, indicating a clear effect of storage time on the oil, and the bands 3008, 2923, 2854, 1747, 1654, 1463, 1377, 1238, 1163, 1099 and 723 exhibited a clear decrease in the intensity of the individual group vibrations, indicating a decrease in oil stability.
