Abstract
In recent years, many studies have focused their attention on the dog as a proper animal model for human cancer. In dogs, mammary tumors develop spontaneously, involving a complex interplay between tumor cells and the immune system and revealing several molecular and clinical similarities to human breast cancer. In this review, we summarized the major features of canine mammary tumor, risk factors, and the most important biomarkers used for diagnosis and treatment. Traditional therapy of mammary tumors in dogs includes surgery, which is the first choice, followed by chemotherapy, radiotherapy, or hormonal therapy. However, these therapeutic strategies may not always be sufficient on their own; advancements in understanding cancer mechanisms and the development of innovative treatments offer hope for improved outcomes for oncologic patients. There is still a growing interest in the use of personalized medicine, which should play an irreplaceable role in the research not only in human cancer therapy, but also in veterinary oncology. Moreover, immunotherapy may represent a novel and promising therapeutic option in canine mammary cancers. The study of novel therapeutic approaches is essential for future research in both human and veterinary oncology.

Abstract
The aim of the study was to investigate the potential of cell-based regenerative therapy for elbow joints affected by osteoarthritis. Interest was focused on two intra-articular applications of amnion-derived mesenchymal stem cells (A-MSCs) to a group of different breeds of dogs with elbow osteoarthritis (13 joints). Two injections were performed 14 days apart. We evaluated synovial fluid biomarkers, such as IFN-γ, IL-6, IL-15, IL-10, MCP-1, TNF-α, and GM-CSF, by multiplex fluorescent micro-bead immunoassay in the treated group of elbows (n = 13) (day 0, day 14, and day 28) and in the control group of elbows (n = 9). Kinematic gait analysis determined the joint range of motion (ROM) before and after each A-MSCs application. Kinematic gait analysis was performed on day 0, day 14, and day 28. Kinematic gait analysis pointed out improvement in the average range of motion of elbow joints from day 0 (38.45 ± 5.74°), day 14 (41.7 ± 6.04°), and day 28 (44.78 ± 4.69°) with statistical significance (p < 0.05) in nine elbows. Correlation analyses proved statistical significance (p < 0.05) in associations between ROM (day 0, day 14, and day 28) and IFN-γ, IL-6, IL-15, MCP-1, TNF-α, and GM-CSF concentrations (day 0, day 14, and day 28). IFN-γ, IL-6, IL-15, MCP-1, GM-CSF, and TNF- α showed negative correlation with ROM at day 0, day 14, and day 28, while IL-10 demonstrated positive correlation with ROM. As a consequence of A-MSC application to the elbow joint, we detected a statistically significant (p < 0.05) decrease in concentration levels between day 0 and day 28 for IFN-γ, IL-6, and TNF-α and statistically significant increase for IL-10. Statistical significance (p < 0.05) was detected in TNF-α, IFN-γ, and GM-CSF concentrations between day 14 and the control group as well as at day 28 and the control group. IL-6 concentrations showed statistical significance (p < 0.05) between day 14 and the control group.

Abstract
This study aimed to evaluate the effects of chicken eggshell powder rich in calcium and the inorganic form of calcium carbonate on osteoporotic bone structure using an animal model of ovariectomized rats. Animals were divided into four groups: sham-operated rats (SHAM group); ovariectomized rats untreated (OVX group); OVX rats treated with eggshell powder (Biomin H® OVX + ECa group; total Ca content 1.5%); and OVX rats receiving inorganic calcium carbonate (calcium carbonate precipitated, total Ca content 1.5%; OVX + ICa group) during 8 weeks. Ovariectomy increased total body weight, plasma alkaline phosphatase activity, cortical bone thickness, periosteal bone apposition, and considerably worsened the trabecular bone microarchitecture. Calcium supplementation in both OVX + ECa and OVX + ICa groups elevated blood supply in the cortical bone when compared to OVX rats. Treatment with eggshell powder, unlike the OVX + ICa group, significantly lowered bone resorption, increased plasma calcium level, relative volume of trabecular bone, and secondary osteon population density, which together contributes to the enhanced bone strength. In addition, sizes of Haversian canals and secondary osteons in OVX + ECa group reached the values of SHAM group. Our results suggest that chicken eggshell powder more effectively ameliorates bone loss in ovariectomized rats than precipitated calcium carbonate.

Abstract
OBJECTIVE Gypsies (or Roma) recently experienced a transition from a traditional to a Westernized lifestyle. Although mortality in this population is 4-fold higher compared with non-Gypsies, very limited information is available on their morbidity especially with regard to non-communicable diseases. Our aim was to determine the prevalence of type 2 diabetes mellitus (T2DM), metabolic syndrome and cardiovascular diseases in Gypsies and non-Gypsies living in the same region of southern Slovakia. MATERIALS AND METHODS We examined 156 Gypsies and 501 non-Gypsies who participated in a population survey. Age- and sex-standardized prevalence rates were computed for each of the following: T2DM, obesity, hyperlipidemia, hypertension, hyperinsulinemia, elevated albumin/creatinine ratio (ACR), metabolic syndrome and cardiovascular disease. RESULTS Age-sex standardized prevalence of T2DM was 30% (95% CI=22-39) in Gypsies and 10% (8-13, P=0.0001 for comparison of ethnic groups) in non-Gypsies. Corresponding prevalence of the other variables are: 65% (56-74) and 30% (26-34, P=0.0001) for obesity, 69% (61-76) and 59% (54-63, P=0.04) for hypercholesterolemia, 66% (59-74) and 39% (35-43, P=0.009) for hypertriglyceridemia, 49% (42-56) and 43% (39-47, P=0.1) for hypertension, 33% (26-50) and 8% (2-14, P=0.002) for hyperinsulinemia, 16% (9-22) and 5% (3-7, P=0.0001) for elevated ACR, 20% (12-27) and 4% (3-6, P=0.0001) for metabolic syndrome and 35% (28-43) and 26% (22-29, P=0.004) for cardiovascular disease. CONCLUSIONS Compared with non-Gypsies, Gypsies had a much higher prevalence of T2DM, metabolic syndrome and cardiovascular disease, which may contribute to their higher mortality.

Abstract
Insulin lispro was compared with regular human insulin with respect to glycaemic control in patients with diabetes mellitus on intensive insulin treatment. Sixty-two patients (55 type 1; 7 type 2) from eight study centres in the Czech Republic, Slovenia and the Slovak Republic participated in a 4-month, open-label, randomized, crossover study. Patients administered insulin lispro immediately before meals or regular human insulin 30 min before meals. A test meal (220-400 kcal), based on local and individual dietary habits and consistent for each patient throughout the study was given at baseline and at the end of each treatment. At each test meal visit HbA1c, fasting blood glucose, 1-hour and 2-hour postprandial blood glucose levels were measured. The level of HbA1c (7.6% +/- 1.5% versus 7.4% +/- 1.5%), incidence of hypoglycaemia (41-66% of patients--versus 39-63%) and daily insulin dose (0.67 +/- 0.11 U/kg versus 0.65 +/- 0.11 U/kg) did not differ between treatment groups at endpoint (insulin lispro versus regular human insulin, respectively). Mean 2-hour postprandial blood glucose excursion for the insulin lispro group (0.0 +/- 3.7 mmol/L) was significantly lower (p = 0.035) when compared with the regular human insulin group (1.3 +/- 3.7 mmol/L) at endpoint. Therapy with insulin lispro was therefore associated with a significant improvement in postprandial blood glucose excursion control when compared with regular human insulin, without an increase in rate of hypoglycaemia.
