We recall the ancient notion of arbelos and introduce a number of concepts generalizing it. We follow the ideas presented by J. Sondow in his article on parbelos, the parabolic analogue of the classic arbelos. Our concepts concern the curves constructed of arcs which resemble each other and surfaces obtained in a similar way. We pay special attention to ellarbelos, the curves built of semi-ellipses,...
The specific nature of poultry production requires conflicts in poultry breeding and husbandry issues to be resolved with the input of veterinarians called to provide expert opinions. The objective of this paper is to analyze veterinary opinions and to determine the most common sources of conflicts related to poultry production. This study was carried out on 147 expert opinions issued by the Department...
The aim of this study was to determine the expression of Ki-67 and PCNA proliferative antigens and the apoptotic index in dogs with various degrees of severity of inflammatory bowel disease (IBD), and to evaluate the applicability of these markers in diagnosing the disease. The study was performed on 28 dogs of different breeds, both sexes, with body weights of 10 to 20 kg, aged 2 to 10 years. The...
This study evaluates the efficacy of budesonide in the treatment of inflammatory bowel disease (IBD) in dogs based on the results of clinical, endoscopic and histopathological examinations. The severity of clinical symptoms was assessed based on CIBDAI scores, and macroscopic and histopathological changes were described in accordance with the recommendations of the WSAVA Gastrointestinal Standardization...
Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used in animals, especially in dogs, to manage pain due to inflammatory disease. This study investigated whether plant drugs can prevent mucosal injury induced by robenacoxib. We used fifteen healthy beagle dogs (7 male and 8 female) aged 4 months, weighing 4.2-5.1 kg at the beginning of the study. Endoscopy and biopsy of the colon were performed...
The effect of inflammatory bowel disease (IBD) on the density of galanin - immunoreactive (GAL-IR) nerve fibers was determined in the mucosa of canine duodenum, jejunum, and descending colon. Fiber densitx was evaluated by a single immunofluorescence method in biopsy specimens obtained from healthy dogs and patients with variable severity of the disease. The densit) of GAL-IR nerve fibers was determined...
In this paper we present the independent solution of problem E3178 posed in 1988 by G.A. Hively in American Mathematical Monthly. We also give a generalization of this problem together with the proof.
