Particle-Induced X-ray Emission Analysis of Serum Trace and Major Elements in Cattle with Acute Coliform Mastitis
The aim of the present study was to examine the applicability of the direct determination of trace and major element concentrations in serum samples collected from Holstein dairy cattle with acute coliform mastitis (n = 53) compared with a healthy control group (n = 39). Twenty-eight elements (Na, Mg, Al, Si, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ce, Ni, Cu, Zn, Ga, As, Se, Br, Rb, Sr, Y, Zr, Nb, Mo, and Pb) were detected by particle-induced X-ray emission (PIXE). Significant differences were observed in serum K, Fe, Zn, and Br concentrations, but not in those of the remaining twenty-four elements. Furthermore, serum Fe concentrations (0.751 ± 0.583 μg/ml, n = 18) were significantly lower in dairy cattle with a poor prognosis than in those with a good prognosis (0.945 ± 0.393 μg/ml, n = 35, P < 0.05) and healthy controls (1.458 ± 0.391 μg/ml, n = 39, P < 0.01). We proposed a diagnostic cut-off point for serum Fe concentrations of <0.82 μg/ml based on receiver operating characteristic (ROC) curves in order to identify cattle with a poor prognosis. The results of the present study indicated that assessing the elemental composition of serum, particularly iron, is a promising prognostic tool for determining the outcomes of cattle with severe acute coliform mastitis

Particle-Induced X-ray Emission Analysis of Elements in Plasma from Wild and Captive Sea Turtles (Eretmochelys imbricata, Chelonia mydas, and Caretta caretta) in Okinawa, Japan
Relationship between postnatal days, serum Cu concentration and plasma diamine oxidase activity in Japanese Black calves
Relationships between Carapace Sizes and Plasma Major and Trace Element Status in Captive Hawksbill Sea Turtles (Eretmochelys imbricata)
The aim of this study was to evaluate the relationships between carapace parameters as indicators of age and plasma elements in 25 captive hawksbill sea turtles. Particle-induced X-ray emission allowed detection of 23 trace and major elements. There were significant but weak correlations between the virtual carapace surface area and plasma bromide (r= -0.552, P<0.01), phosphorus (r=0.547, P<0.01), lead (r=-0.434, P<0.05) and strontium (r=0.599, P<0.01), while there were no significant correlations with other elements. These results suggest that major and trace plasma elements in captive sea turtles show almost no variation with carapace parameters, suggesting that the increase in plasma elements seen in wild sea turtles might be the result of marine pollution
