The present study aims to establish the content of natural trans fatty acids (TFA), biologically active and anticancerogenic components in cow's milk, obtained from the Bulgarian Rhodope Cattle breed and the curd produced by it during the lactation, and to evaluate the fatty acid composition of milk fat as a healthy source of human nutrition. The insurance of livestock with nutritional resource rich of linoleic and alpha linolenic acid on pasture grass rearing cows leads to an increase the quality in the fat fraction of milk in terms of biologically active fatty acids-omega-3, omega-6, CLA, trans and cis-fatty acids and decreases the amount of saturated fatty acids. The production of curd does not lead to substantial changes in the fatty acid composition resulting from well-conducted and respected technological processing. The assessment of the lipid preventive score, atherogenic and thrombogenic index in the milk and the curds produced by it give us an idea of the usefulness of the given product-high lipid preventive score and atherogenic index (over 1.0) and low cholesterolemic index (less than 1.0). The studied cow's milk are characterized by product as low content of trans fatty acids (from 0.11 to 0.21 g / 100 ml product) and high amount of saturated fatty acids, the results obtained of curd are similarly-product with low content of trans fatty acids (0.34 to 1.09 g/100g product) and a high amount of saturated fatty acid content (from 12.63 to 19.96 g/100g product).

The effect of treatment with aqueous antioxidant extracts of oregano (Origanum vulgare L.) and wild basil (Clinopodium vulgare L.) in refrigerated storage of raw poultry meat was studied. Physicochemical analyzes of meat samples were performed - total protein, ash, fat, dry matter, cooking loss and pH value in dynamics. The content of malondialdehyde (MDA) and the protein profile were determined. The microorganisms’ growth rate in meat during storage at 4°C for a period of 14 d was monitored. After the 7th d, the total number of mesophilic microorganisms in the meat samples increased to 7.00 log cfu/g, which is indicative of decay. A significant increase in pH value was observed after 14 d of storage, but there were no significant changes in total protein content and protein profile. In all meat samples, the amounts of MDA on days 7 and 14 were significantly below the thresholds indicated in the literature. Experimental groups treated with extracts showed lower values for MDA content compared to the control, which is an indication of certain inhibition of lipid oxidation processes in meat.

Background and Objectives: Atraumatic intrapelvic protrusion of the acetabular component following excessive reaming of the acetabulum with a far medial positioning of the cup is a rare, but serious complication of a total hip arthroplasty (THA). This study analyzes the factors contributing to this uncommon complication and presents the outcome after the revision surgery using the Ganz reinforcement ring combined with a bone graft and plating of the posterior column and/or screws for the anterior column. Materials and Methods: A retrospective case series study with seven patients (four males, mean age 76 ± 10 years (60–86)) that underwent a revision THA within 24 ± 17 days (5–60) after an atraumatic periprosthetic acetabular fracture with a medial cup protrusion was performed. All fractures were reconstructed with a Ganz reinforcement ring and bone graft with a mean follow-up of 1.7 ± 1.7 years (0.5–5). Radiographs were evaluated for the following: (i) cup positioning immediately after the primary THA and the revision surgery, (ii) cup migration in the follow-up, and (iii) fracture healing. Results: The position of the acetabular component as assessed on the postoperative radiographs after the index surgery and before the complete medial cup protrusion showed a cup placement beyond the ilioischial line indicative of a fracture of the medial wall. The revision surgery with the reconstruction of the medial wall with a Ganz reinforcement ring combined with a bone graft restored in the presented cases the center of rotation in the horizontal direction with a statistical significance (p < 0.05). During the follow-up, there was no aseptic loosening with the relevant cup migration or significant change in the position of the acetabular cup at the final follow-up (p > 0.05) after the revision. All seven fractures and bone grafts realized a bone union until the latest follow-up. Conclusions: Following excessive reaming, the acetabular component was placed too far medially and resulted in an intrapelvic cup protrusion. An unstable cup following a fracture of the medial wall was evident on the immediate postoperative radiographs. In the case of the medial wall perforation with an intrapelvic cup protrusion after the primary THA, the reconstruction with a Ganz reinforcement ring was a successful treatment option resulting in the fracture healing and a stable cup positioning. Surgeons should be aware of that rare and probably underreported complication and restore the anatomic center of rotation by treating the defect intraoperatively.
