Determination of Aflatoxins and Selected Heavy Metals in Rice Varieties Cultivated in Fogera, Amhara Region, Ethiopia

open access: yesFood Chemistry International, EarlyView.
ABSTRACT Rice (Oryza sativa L.) is a vital staple crop for nearly half the world's population. This study investigates the levels of aflatoxins (AFB1, AFB2, AFG1, and AFG2) and selected heavy metals (Cd, Pb, and Cr) and essential elements (Mn, Fe, Mg, Cu, and Zn) in rice varieties cultivated in Fogera, Amhara Region, Ethiopia.

[Basal metabolism and respiratory quotient in obese children].

open access: yesLa Pediatria medica e chirurgica : Medical and surgical pediatrics, 1999
Childhood obesity represents an increasing dysmetabolic condition. The aim of our study was to evaluate the influence of Fat Mass (FM%) on Resting Metabolic Rate (RMR) and Respiratory Quotient (RQ) as indicator of substrate oxidation. FFM and FM were estimated by bioelectrical impedance analysis (BIA), using the Kushner equation. Resting metabolic rate
