The sample consisted of 40 female participants extracted from a population of elementary school students from Nis, age 12 ± 6 months, who regularly participated in their physical education classes. The basic aim of the research was to determine the influence of programmed contents of regular physical education classes on the development of the motor agility and functional abilities of the participants. The research problem was the evaluation of whether under the influence of physical education in the curriculum we can achieve a statistically significant increase in the level of the motor agility and functional abilities of the participants. By using the student t-test for small dependent samples and the canonical discriminant analysis, we determined that under the influence of physical exercise, at the end of a three-month period of physical education classes, a statistically significant increase in the level of motor agility and functional abilities of the participants was determined.

The research was carried out on a sample of 55 female high school students from Nis, 15 years of age (± 6 months). The aim of the research was to determine the canonical correlations between morphological dimensions, on the one hand, and tests for the evaluation of repetitive strength on the other, among the female students. The problem of this research was the evaluation of the influence of morphological dimensions on the achieved results for repetitive strength. 10 anthropometric measurements of morphological characteristics were used, which define longitudinal dimensionality and dimensionality of the skeleton, transversal dimensionality of the skeleton and circular dimensionality and body mass. Repetitive strength was evaluated by means of three tests. The results of the canonical correlation analysis have shown that a significant canonical factor can be found between the morphological dimensions (as the predictor system) and explosive strength (as the criterion system), along with a high corre analysis.

The aim of this study was to research the impact of a diet supplemented with egg yolks of modified content, having in mind the type of fat added to the laying hens diet, on the brain lipids and their fatty acid composition in rats. During four weeks of the experiment, 64 Wistar rats, divided into four groups of 16 animals each (eight animals of both sexes), were fed the commercial rat feed (group C), or the feed that contained 70% of the commercial rat feed and 30% of freshly boiled yolks from the eggs originating from laying hens fed with 3% fish oil (group F), 3% palm olein (group P) or 3% lard (group L). Concentration and content of total lipids and total cholesterol, as well as the fatty-acid composition of the total brain lipids were determined in the lipid extracts of the rats brains. Under unfavourable conditions, which in our case could be high dietary intake of the total fat due to egg yolk addition, the amount of total fat in the brain tissue or the mass of the organ itself can be changed. Applied dietary treatments could also influence the level of de novo synthesis of total cholesterol in the rat brain. High dietary fat intake, as well as the fat quality regarding its fatty acid composition, appear to be able to significantly influence the fatty acid profile of the total brain lipids in adult rats, whereas the level and quality of the changes also depend on sex.

The aim of this study was to examine the effects of diets supplemented with egg yolks of modified composition on the fatty-acid composition and lipid content in rat’s liver. During four weeks of the experiment 64 Wistar rats were divided into four groups of 16 individuals each (eight individuals of both sexes) and fed a commercial feed mixture for rats (group C) or diet containing 70% commercial mixture for rats and 30% freshly cooked egg yolks from laying hens fed diets with 3% fish oil (group F), 3% palm olein (group P) or 3% lard (group L). Dietary supplementation with egg yolks significantly increased the hepatic cholesterol pool in rats, regardless of the type of fat in the diet of laying hens from which the eggs originated. The content of α-linolenic acid in the liver of male rats in group P was 4-6 times higher compared to males in the other groups. Liver lipids and their fatty-acid composition differ by both, sex and dietary modified egg yolk composition in rats.

Goal: To investigate the correlation between TSH and HbA1c in the treatment of L-thyroxine in the process of glycemic control in patients with subclinical hypothyroidism. Patients and methods: The sample consisted of 100 patients, mean age 51.75±3.23 years, BMI=27.97±4.52 kg/m2, with SH (TSH>4.2 mU/L and normal serum T3 and T4). Laboratory diagnosis included the determination of free T3, free T4, thyroid antibodies, Tg, insulin, C-peptide and glucose during the OGTT, HbA1c, CRP and lipid levels. 20 patients with SH had prediabetes and 38 patients had DM. All patients were treated with low doses of L-thyroxine (25-50ug) and all were physically active. Results: After 6 months of treatment with L-thyroxine, the patients had normal or decreased TSH (5.85±0.92 vs. 3.54±0.55 mU/L), insulin levels (114.64±24.11 vs. 96.44±17.26 pmol/L) significantly reduced HbA1c (6.74±1.01 vs. 6.26±1.12) is reduced. Conclusion: The correlation between TSH and HbA1c was positive and significant (r=0.46). This indicates a significant effect of treatment with L-thyroxine on glycemic control in patients with subclinical hypothyroidism.

AIMS We examined effects of treatment with 1-thyroxin on glucose regulation in patients with subclinical hypothyroidism. METHODS The study included 100 patients, ages 51.75 +/- 13.23 years, BMI = 27.97 +/- 4.52 kg/m2, with SH (TSH > 4.2 mU/L and with normal level of T3 and T4). Laboratory evaluation included serum free T3, free T4, TSH, thyroid antibodies, TGL, insulin, C-peptide and glucose during OGTT, HbA1c, CRP and level of lipids. Percentile, average and correlation analysis have been utilized in statistical analysis. Twelve patients with SH had GI and 38 patients had DM. All patients were treated with low dose of 1-thyroxin (25-50 ug) and high physical activity. RESULTS After 6 months treatment with 1-thyroxin, patients had normal or limited TSH (5.85 +/- 0.92 vs. 3.54 +/- 0.55 mU/L), level of fasting insulin (114.64 +/- 24.11 vs. 96.44 +/- 17.26 pmol/l) significantly decreased, HbA1c (6.74 +/- 1.01 vs. 6.26 +/- 1.12) decreased as well. The level of CRP significantly decreased as well (2.27 +/- 0.8 vs. 3.32 +/- 1.1 mg/l). The changes were and in level of total cholesterol (5.39 +/- 0.57 vs. 6.10 +/- 0.67 mmol/l), triglyceride levels (1.69 +/- 0.37 vs. 2.22 +/- 0.49 mmol/l), HDL cholesterol (1.16 +/- 0.14 vs. 1.03 +/- 0.15 mmol/l) and LDL cholesterol (3.79 +/- 0.64 vs. 4.37 +/- 0.77 mmol/l). The correlation between TSH and HbA1c was positive and significant (r = 0.46). CONCLUSION The normalization of TSH resulted in decrease of level of fasting insulin, fasting and postprandial glucose, CRP and lipids. Higher CRP associated with fasting hyperinsulinemia before insulin resistance has been evidenced in most patients with SH. These data support an important role of treatment of SH in support of glucose regulation.

Animal waste due to its characteristics, increasing the quantity and inadequate disposal of a major environmental problem, because it potentially threatens all aspects of the environment, with unpredictable consequences. in general we can conclude that the animal waste inappropriately disposed of in Bosnia and Herzegovina. Therefore, certain measures are taken to create conditions for sustainable management of this type of waste. Adoption of certain regulations by which it is legally standardized treatment of waste, including animal waste, such as: Regulation on conditions for the incineration of waste, Regulation on issuing permits for the activities of small business in the Waste management Regulations on animal waste and other non-hazardous materials natural origin, which can be used for agricultural purposes and other regulations. in principle, the most acceptable method of waste disposal are those that provide environmental benefits and economic benefits. one of the environmentally and economically acceptable methods of waste disposal, especially animal, is burning to the use of waste heat through electricity or heat or steam. in this paper the disposal of animal waste by burning the plant is designed and implemented with appropriate technological conditions for burning to ensure complete combustion and minimum emissions of pollutants into the atmosphere. This avoids burdening the environment with the waste, relieves municipal landfill, preventing harm human health due to inadequate care and achieve economic benefits, which is consistent with the principles of waste management. This work is founded on the basis of its own research environmentally and economically acceptable disposal procedures of animal waste, such as thermal treatment for heat production and anaerobic digestion for biogas production.
