Review ArticleOpen accessIn the abstractCoenzyme Q10 and its Effective SourcesHamideh Vaghari, Roholah Vaghari, Hoda Jafarizadeh-Malmiri, Aydin BerenjianCoenzyme Q10 (2,3-dimethoxy, 5-methyl, 6-decaprenyl benzoquinone, CoQ10) is naturally present in many organisms. It has key roles in several biochemical pathways. CoQ10, as an electron and proton carrier for energy coupling leads to Adenosine Triphosphate (ATP) formation. Furthermore, in medicine, the pharmacological use of CoQ10 has attracted more attention due to its benefits in treating cardiovascular and degenerative neurologic diseases. … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 4 · 10 Oct 2016 · 9,283 accessesView PDFCite
Research ArticleOpen accessIn the abstractDurum Wheat Seed Germination Response to Hydrogel Coatings and Moisture under Drought StressMaya Hotta, James Kennedy, Clement Higginbotham, Noreen MorrisTechnologies that can increase crop production while maintaining low pollution are essential for sustainable agriculture. This study compares the germination performance of Durum wheat seeds (Triticum durum Desf.) which were coated with synthetic coatings [polyacrylamide (PA)] and novel natural coatings [mixtures of agar/ι-carrageenan (AC)] at different moisture levels. A number of germination performance indicators were measured for each of the … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 2 · 2 May 2016 · 8,427 accessesView PDFCite
