AB  - Honey bees are essential to sustaining ecosystems, contributing to the stability of biodiversity through pollination. Today, it is known that the failure of pollination leads irremediably to the loss of plant cultures and, as a consequence, inducing food security issues. Bees can be affected by various factors, one of these being Nosema spp. which are protozoans specifically affecting adult honey bees and a threat to bee populations around the world. The composition of the phytotherapeutic product (Protofil®) for treating nosemosis was analyzed from a biochemical point of view. The most concentrated soluble parts in the phytotherapeutic association were the flavonoids, most frequently rutin, but quercetin was also detected. Additionally, the main volatile compounds identified were eucalyptol (1.8-cineol) and chavicol-methyl-ether. To evaluate the samples’ similarity–dissimilarity, the PCA multivariate statistical analysis, of the gas-chromatographic data (centered relative percentages of the volatile compounds), was applied. Statistical analysis revealed a significant similarity of Protofil® with the Achillea millefolium (Yarrow) samples and more limited with Thymus vulgaris (Thyme) and Ocimum basilicum (Basil), and, respectively, a meaningful dissimilarity with Taraxacum officinale (Dandelion). The results have shown a high and beneficial active compounds concentration in the analyzed herbs. High similarity with investigated product recommending the Protofil®, as the treatment compatible with producing organic honey.

AB  - Determining the post-mortem interval (PMI) is often a very demanding and delicate job which requires a good knowledge of postmortem changes. In this study, 20 domestic pig carcasses (Sus scrofa) whose death occurred within 8 h before the start of the study were simultaneously laid at the same geographical location, but in different environments (on the ground surface - S; buried in the ground - G; placed in a crate and buried in the ground - C; submerged in water - W; and hanging in the air - A). One carcass from each group was sampled on days 14, 28, 120 and 190 from the beginning of the experiment, and on that occasion, a detailed analysis of postmortem changes and an autopsy was carried out. The difference in the rate of decomposition among groups was statistically significant. The fastest decomposition occurred in carcasses placed in a crate and buried, because during the winter period the temperature in the air was below 0 degrees C. At that time, the decomposition process and the insect activity were slowed or stopped on carcasses in groups S, A, W, and G to some extent, while the ground and wooden crate were good thermal insulators for group C carcasses arid provided better conditions for insect activity.
