The protective role of glycine and glutamic acid against the toxic effects of oxidized oil was studied for the first time. Mustard seed oil was thermally oxidized and characterized for quality characteristics and polyphenolic composition using reversed phase HPLC-DAD. Significant changes in the quality characteristics occurred with thermal oxidation. Fourteen polyphenolic compounds were identified and quantified in oils. Quercetin-3-glucoside, quercetin-3-feruloylsophoroside, catechin, quercetin-3-rutinoside, quercetin-3,7-diglucoside, sinapic acid and vanillic acid hexoside were the major compounds in the fresh and oxidized oil. Oxidized, un-oxidized mustard oils, glycine and glutamic acid were given to rabbits alone or in combination. The biochemical responses were studied in terms of haematological and biochemical parameters and histopathology. It has been observed that biochemical and haematological parameters were adversely affected by the oxidized oil, while supplementation of both amino acids was beneficial in normalizing these parameters. Both amino acids alone have no significant effects, however, oxidized oil affected the liver by enhancing fat accumulation, causing hepatitis, reactive Kupffer cells and necrosis. The co-administration of oxidized oils with glycine or glutamic acid revealed significant recovery of the liver structure and function. In conclusion, glycine or glutamic acid is beneficial and protective against food toxicity and can be considered as an ameliorative food supplement.
Cotton leaf curl disease (CLCuD) is the most important limiting factor for cotton production in Pakistan The CLCuD passed through two major epidemics in this region with distinct begomoviruses/satellites complexes. Since 2015 the disease has again started to appear in epidemic form, causing heavy losses to cotton crop, which we termed as the “third epidemic”. We applied CIDER-seq (Circular DNA Enrichment Sequencing), a recently developed sequencing method for PCR-free virus enrichment to produce a full length read of a single circular viral genome coupled with Sanger sequencing to explore the genetic diversity of the disease complex. We identified a highly recombinant strain of Cotton leaf curl Multan virus (CLCuMuV) and a recently evolved strain of Cotton leaf curl Multan betasatellite (CLCuMuB) that are dominant in all major cotton growing regions in the country. Moreover, we also identified multiple species of alphasatellites with one distinct species, Mesta yellow vein mosaic alphasatellite (MeYVMA) for the first time in cotton. Relative abundance of virus and associated satellites was also determined by real time quantitative PCR (RT-qPCR). To the best of our knowledge, this is the first study determined the CLCuD complex associated with its 3rd epidemic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
