Tiger nut (Cyperus esculentus) was subjected to different fermentation methods such as traditional, back slope and control. The raw and fermented samples were analyzed for mineral, amino and fatty acids. The results of mineral analysis revealed potassium and sodium as the most abundant mineral element with their value ranging from 546 to 91.6 mg/100 g and 64.00 to 3383.33 mg/100 g, respectively while copper was found in...

Anemia constitutes a serious health problem in many tropical countries including Nigeria because of the prevalence of malaria and other parasitic infections which possibly leads to decrease of hemoglobin. Fluted pumpkin has been reported to be very good in building the constituents of the blood and also replacing them. This study was designed to investigate the effects of the aqueous leaf extract of fluted pumpkin on... Read more.

The binding of glucose to serum proteins in a non-enzymatic reaction occurs proportionately to the prevailing serum glucose concentration during the lifespan of each protein. The non-enzymatic reaction of proteins with reducing sugars results in the formation of glycated proteins that are indicative of the relative amount of reducing sugars present. Hemoglobin, albumin, lipoproteins and other tissue proteins can be... Read more.
