Use of nanoscale metals in poultry diet as a mineral feed additive.

The research was aimed at studying the efficiency of a nanoscale alloy of copper (Cu) and zinc (Zn) to be used as a mineral additive for feeding broiler chickens, compared to inorganic and organic forms of these elements. Biochemical studies of the blood serum were performed using an automated analyzer. The mineral composition was determined by atomic emission and mass spectrometry (MS-ISP).

Left ventricular myocardial remodeling in dogs with mitral valve endocardiosis.

Background And Aim: Left ventricular myocardial remodeling could play an important role in the progression of chronic heart failure (CHF) syndrome in dogs with mitral valve endocardiosis. The aim of this study was to evaluate the left ventricular myocardial remodeling in dogs with mitral valve endocardiosis and to study the dependence of the incidence of this pathological phenomenon on the functional class (FC) of progression of the CHF syndrome.

Materials And Methods: A total of 108 afflicted dogs and 36 clinically healthy dogs were examined using transthoracic echocardiography.
