Assessment of serum selenium levels in 2-month-old sucking calves using total reflection X-ray fluorescence technique

Atomic spectrometry update. Clinical and biological materials, foods and beverages

“…Selenium depletion was found in 2-month old suckling calves using TXRF measurement of Se in serum. In this study, reported by Buoso et al, 62 Se concentrations in the serum of 78 calves ranged from 10 to 66 mg l 21 , lower than the expected range (60-80 mg l 21 ). The results corroborated a clinical diagnosis of Se deficiency.…”

The Use of X‐Ray Techniques in Medical Research

“…For Se determination in serum samples of 60-day-old calves a direct method was developed [44]. Yttrium was used as the internal standard and found to be adequate for measurements of Se at low concentrations (20-50 ng/mL).…”

Atomic spectrometry update. X-ray fluorescence spectrometry

“…Significant differences were found between the normal and the cancer group, whose values were 1.1 and 0.7, respectively. Buoso et al 140 studied the Se levels in suckling calves in order to diagnose Se deficiency in the population and found mild to severe deficiencies. Human amniotic fluid and placenta were analyzed by Carvalho et al 141 to study the relationship of child weight to maternal age.…”
