Nutrigenomic studies of orange juice and vitamin c on gene expressions in neuronal tissues of Sprague Dawley rats

  Nutrigenomics, a nascent field in nutrition and molecular biology plays a pivotal role in understanding the influence of bioactive dietary components on the structure, integrity and functions of the genome. In this study, the comparative effects of vitamin C (Vit C) and Nigerian local orange juice on the gene expression levels of superoxide dismutase (sod), tumour necrosis factor receptor...

Oxalate metabolism by Sclerotinia sclerotiorum, a fungal pathogen in soybeans

  Pathogenesis of Sclerotinia sclerotiorum mainly depends on production of oxalate (Lib.) de Bary, but the mechanism by which the oxalate is produced is not well understood. Control of Sclerotinia stem rot (SSR) in soybean which is caused by this ubiquitous phytopathogenic fungus requires the knowledge of oxalate synthesis by S. sclerotiorum. Nine isolates from infected soybeans and soils were...
