Therefore, the aim of the study was to assess the usefulness of two biomarkers, i.

Measurement of ITIH4 and Hp levels in bitches with pyometra using newly developed ELISA methods.

Measurement of acute phase proteins (APPs) as biomarkers in canine medicine is in increasing demand. In the present study, the development and validation of two ELISA methods for the quantification of canine inter-alpha-trypsin inhibitor heavy chain 4 (ITIH4) and haptoglobin (Hp) are shown. The adequate imprecision and accuracy and wide analytical range make the developed methods appropriate to quantify ITIH4 and Hp in serum samples.

Decorin concentrations in canine normal and neoplastic mammary gland tissues.

In the present study, the concentration of decorin in canine normal and neoplastic mammary gland tissues was examined to understand the potential role of decorin in development and progression of canine mammary tumours. The homogenates of 48 mammary gland tumours (10 benign and 38 malignant) and 10 samples of normal canine mammary gland tissue were used in the study. The presence and quantification of decorin was examined in the homogenates using Western blot and specific canine ELISA.

The influence of the duration of the expulsive stage of parturition on the occurrence of postpartum oxidative stress in sows with uncomplicated, spontaneous farrowings.

The aim of the study was to determine the influence of the duration of the expulsive stage of parturition on the occurrence of postpartum oxidative stress in sows with uncomplicated, spontaneous farrowings. Twenty-five pregnant gilts were divided into three groups on the basis of duration of the expulsive stage of farrowing: (I) duration of the expulsive stage was below 3 hours; (II) duration of the expulsive stage ranged from 3 to 6 hours; (III) duration of the expulsive stage was longer than 6 hours. Blood samples were collected at 24 to 48 hours before and 24 hours after parturition.
