Background: Simultaneous analysis of epinephrine and tyrosine as two effective and important biological compounds in human blood and urine samples are very important for the investigation of human health. Objective: In this research, a highly effective voltammetric sensor fabricated for simultaneous analysis of epinephrine and tyrosine. The sensor was fabricated by the modification of glassy carbon electrode with ZnO-Pt/CNTs nanocomposite (ZnO-Pt/CNTs/GCE). The synthesized nanocomposite was characterized by SEM method. The ZnO-Pt/CNTs/GCE showed two separated oxidation signals at potential ~220 mV and 700 mV for epinephrine and tyrosine, respectively. Also, we detected linear dynamic ranges 0.5-250.0 µM and 1.0-220 µM with a limit of detections 0.1 µM and 0.5 µM for the determination of epinephrine and tyrosine, respectively. The ZnO-Pt/CNTs/GCE was used for the determination of epinephrine and tyrosine in blood serum and human urine samples.

Early pregnancy detection is vital for properly managing livestock farms by re-inseminating nonpregnant females and minimizing the calving intervals. The present investigation was executed to compare a rapid test (Dairy Cow Pregnancy Test from Span Biotech Ltd. Shenzhen, China) with a commercial bPAG ELISA test (IDEXX®) for pregnancy diagnosis in non-descriptive cows. The study also aimed to elucidate if the rapid test could be an alternative method to ELISA in the field. Blood and urine samples were collected from 43 cows to measure the concentrations of bovine pregnancy-associated glycoproteins (bPAGs) in the blood samples and detect progesterone via the rapid test in the urine samples. Examining the genital tracts was achieved after slaughtering the cows to determine the uterus’ state, used as the reference standard for both tests. The results showed that the bPAG ELISA test was more accurate in pregnancy detection than the rapid test. However, there were no statistically significant differences (P > 0.05) between both methods’ results. We conclude that the rapid test can be a suitable alternative method to the bPAG ELISA test for diagnosing pregnancy in cows in field conditions.
