In recent years, artificial neural networks have become the subject of intensive research in a number of scientific areas. The high performance and operational speed of neural models open up a wide spectrum of applications in various areas of life sciences. Objectives pursued by many scientists, who use neural modelling in their research, focus - among others - on intensifying real-time calculations. This study shows the possibility of using Multilayer-Perceptron (MLP) and Radial Basis Function (RBF) models of artificial neural networks for the future development of new methods for animal science. The process should be explained explicitly to make...

The objective of the study was to investigate the effect of pre-synchronisation on the occurrence of the oestrus and pregnancy rate after fixed time artificial insemination (FTAI) in synchronised ewes during the anoestrous season. Kivircik ewes (n = 84) were randomly assigned to one of the two treatment groups with (PRE; n = 42) or without (SYN; n = 42) pre-synchronisation. In the SYN group, the ewes were subjected to a 7-d short-term protocol (P4 insertion-6d-PGF2α-1d-P4 removal + eCG). In the PRE group, the same short-term protocol as in the SYN group was applied with 7 days apart for a pre-synchronised synchronisation...

Fifty-five healthy conscious dogs were included in a prospective randomised double-blinded clinical study. The dogs allocated to one of four groups received intravenous bolus followed by infusion of fentanyl (FEN-group), or ketamine (KET-group), or lidocaine (LID-group), or saline (SAL-group). The intraocular pressure (IOP), pupil size (PS), heart rate (HR) and mean arterial pressure (MAP) were measured prior to and at 2, 5, 10, 20 and 30 min after initiation of the drug administration. The data were analysed using an analysis of variance and the Steel-Dwass test. No significant difference in the IOP within or between the groups was detected. In the...
Albumin infusion ameliorates liver injury in streptozotocin-induced diabetic ratsOriginal Paper

We investigated the effect of an albumin infusion on the enzyme activity, expression level of cytochrome P450 2E1 (CYP2E1), and oxidative stress in the serum and liver of streptozotocin (STZ)-induced diabetic rats. The STZ treatment enhanced the alanine aminotransferase and aspartate aminotransferase activities in the rat serum compared with those in the untreated rats. Treatment with STZ elevated the expression and catalytic activity of CYP2E1, and the oxidative stress, and decreased the reducing potentials in the liver, suggesting the possibility of diabetes-induced liver injury. Moreover, the antioxidant activity of the serum albumin decreased in...

A case of a nine-year-old, intact female, American Bulldog with a heart mass is described. Echocardiography was used to identify this pathological lesion. Part of the mass and pericardial sac were surgically removed for histopathological examination. A final diagnosis of neuroendocrine carcinoma was diagnosed by necropsy and histopathology. To the author's knowledge, there is very limited information in the literature about this pathology.
Congestive heart failure in a veiled chameleon (Chamaeleo calyptratus): A case reportCase Report

A two-year-old male veiled chameleon (Chamaeleo calyptratus) was referred for a gular oedema and bilateral blepharoedema. The echocardiography revealed a ventricular hypertrophy, pericardial effusion, and valvular regurgitation of the right atrioventricular valve. Treatment with hydrochlorothiazide, enalapril, and carvedilol was commenced. Within 3 weeks of treatment, the valvular regurgitation was noticeably decreased. In the 4th week of treatment, the echocardiography revealed a reduction in the myocardium hypertrophy. After an additional month of home treatment, the patient was presented with anorexia and decreased activity....
