Physical and chemical properties of Brassicaceae oil as lubricant
Rapeseed oil and canola oil have traditionally been used in industrial lubricant applications but oils of many species of Brassicaceae have similar properties. Oil from the seed of seven Brasicaceae species, Sinapis alba (yellow mustard), Camelina sativa (false flax), Brassica carinata (Ethiopian mustard), B. napus (rapeseed), B. juncea (oriental mustard), B. rapa (field mustard) and S. arvensis (wild mustard), were recovered by cold pressing and filtration without further refining. The physical and chemical properties of the oils were determined. B. napus had the highest oil yield when extracted by cold press and B. juncea* (low erucic B. juncea) had the highest oil content extracted by solvent extraction. C. sativa oil had the lowest sterol content, mineral content, oxidative stability, and viscosity at 40 and 100°C among tested oils and had the highest iodine value. Iodine value had a strong negative correlation with oxidative stability in the tested oils. There was not any water in any of the oil samples. Overall, C. sativa oil had properties making it suitable for use as a fuel although its low oxidative stability and high in iodine value could pose challenges; however, S. alba oil was more appropriate for use as a lubricant.

Automatic thoughts may be risk factors for depression and anxiety, and should be detected early. However, the genetic basis of automatic thoughts remains unclear. This study aims to investigate the genetic association of automatic thoughts with SNPs (single nucleotide polymorph ... more
Copper deficiency had been suggested to link between fructose‐enriched diet (FED) and the development of non‐alcoholic fatty liver disease (NFALD). In this study, we characterized changes in hepatic copper concentrations and hepatic oxidative milieu, in rats with the metabolic s ... more

A new study from the University of Southern California (USC) has found a link between recreational marijuana use and an increased risk of developing subtypes of testicular cancer that tend to carry a somewhat worse prognosis. Published in CANCER the findings suggest that the potential cance ... more
Researchers in the United States have developed a medical model for regenerating bladders using stem cells harvested from a patient’s own bone marrow. The research, published in STEM CELLS, is especially relevant for paediatric patients suffering from abnormally developed bladders, but also ... more
