When an alcohol fuel was used with potassium hydroxide added to the fuel stream and oxygen was the oxidant, the following maximum power densities were achieved at 60 degrees C: ethanol (128 mW cm(-2)), 1-propanol (101 mW cm(-2)), 2-propanol (40 mW cm(-2)), ethylene glycol (117 mW cm(-2)), glycerol (78 mW cm(-2)), and propylene glycol (75 mW cm(-2)). We also observed a maximum power
density of 302 mW cm(-2) when potassium formate was used as the fuel under the same conditions. However, when potassium hydroxide was removed from the fuel stream, the maximum power density with ethanol decreased to 9 mW cm(-2) (using oxygen as oxidant), while with formate it only decreased to 120 mW cm(-2) (using air as the oxidant). Variations in the performance of each fuel are discussed. This fuel-flexible fuel cell configuration is promising learn more for a number of alcohol fuels. It is especially promising with potassium formate, since it does not require hydroxide added to the fuel stream for efficient operation.”
“Mahonia is an important medicinal plant used for the treatment of human diseases. To explore the molecular mechanism’s underlying the different pharmacological functions of Mahonia, organ-specific proteomics was performed. Protein profiles of leaves, stems, and roots from 2-year-old Mahonia plants were determined using gel-free/label-free
Cilengitide proteomic technique, and totals of 304, 314, and 182 proteins were identified, respectively, and included 36 common proteins. In leaves, the most abundant proteins related to photosynthesis. Furthermore, polyethylene glycol fractionation was used to identify low-abundance proteins in leaves. With this approach, oxidative pentose phosphate-related proteins were identified in leaves. In stems, the main functional categories of proteins were protein synthesis and redox ascorbate/glutathione metabolism. In roots, proteins were mainly related to protein synthesis, stress, and amino acid metabolism. Of the proteins identified, the abundance of calreticulin was markedly higher in roots than that Dibutyryl-cAMP molecular weight detected in stems and leaves. Many roots-specific proteins, including
S-adenosylmethionine synthetase and (S)-tetrahydroprotoberberine oxidase, involved in the biosynthesis of alkaloids, were identified. Consistent with this finding, levels of the alkaloids, which were columbamine, jatrorrhizine, palmatine, tetrandrine, and berberine, were markedly higher in roots compared to those detected in stems and leaves. Taken together, these results suggest that alkaloid biosynthesis is an important function in Mahonia roots.”
“Background: Mental disorders are the main reasons for rising proportions of premature pension in most high-income countries. Although inpatient medical rehabilitation has increasingly targeted work-related stress, there is still a lack of studies on the transfer of work-specific interventions into work contexts.
