Učinak dodatka proteina iz otpada kože na hematološke i biokemijske pokazatelje metabolizma i mliječnost visokoproduktivnih krava

This study was aimed to establish the effect of a fodder protein supplement from minced subcutaneous epithelium of farm animals on hematological, biochemical parameters of metabolism and milk productivity of high-yielding cows during the early lactation. For this, three groups of cows, six animals each, were formed according to the principle of analogous pairs. The control group received the main diet, the second and third experimental groups were daily fed with 300 g and 500 g of protein supplement for 60 days in addition to the main diet, respectively. The effect of prolongation of the supplement was studied over the next 30 days. Hematological and biochemical blood parameters, qualitative and quantitative composition of milk were studied in all animals. The animals of the experimental groups showed an increase in metabolic and redox processes during the experiment. An increase in the metabolism of nutrients in the liver has been found. Due to the sufficient intake of protein in the organism of animals, there was an increase in milk productivity and milk quality indicators.Cilj je ovog istraživanja utvrditi učinak dodatka proteina iz mljevenog potkožnog epitela domaćih životinja, na hematološke i biokemijske parametre metabolizma te proizvodnost visokoproduktivnih krava tijekom rane laktacije. Za to su prema principu analognih parova formirane tri skupine krava, svaka po šest životinja. Kontrolna skupina hranjena je osnovnim obrokom, a druga i treća eksperimentalna skupina svakodnevno su uz osnovnu hranidbu hranjene s 300 g i 500 g proteinskog dodatka tijekom 60 dana. Učinak dodatka proučavan je tijekom sljedećih 30 dana. U svih životinja proučavani su hematološki i biokemijski parametri krvi, te kvalitativni i kvantitativni sastav mlijeka. Životinje pokusnih skupina pokazale su porast metaboličkih i redoks procesa tijekom pokusa. Utvrđen je porast metabolizma hranjivih sastojaka u jetri. Zbog dovoljnog unosa proteina u organizam životinja eksperimentalnih skupina došlo je do povećanja pokazatelja mliječne proizvodnosti i pokazatelja kvalitete mlijeka

Building analytical platform with Big Data solutions for log files of PanDA infrastructure

The paper describes the implementation of a high-performance system for the processing and analysis of log files for the PanDA infrastructure of the ATLAS experiment at the Large Hadron Collider (LHC), responsible for the workload management of order of 2M daily jobs across the Worldwide LHC Computing Grid. The solution is based on the ELK technology stack, which includes several components: Filebeat, Logstash, ElasticSearch (ES), and Kibana. Filebeat is used to collect data from logs. Logstash processes data and export to Elasticsearch. ES are responsible for centralized data storage. Accumulated data in ES can be viewed using a special software Kibana. These components were integrated with the PanDA infrastructure and replaced previous log processing systems for increased scalability and usability. The authors will describe all the components and their configuration tuning for the current tasks, the scale of the actual system and give several real-life examples of how this centralized log processing and storage service is used to showcase the advantages for daily operations

Comparative Evaluation of Custom-Made Components and Standard Implants for Acetabular Reconstruction in Revision Total Hip Arthroplasty

Background.The use of custom-made acetabular components is one of the promising methods for reconstruction of the acetabulum in cases of significant defects, including those associated with pelvic bone dissociation. It allows achieving stable fixation and restoring the biomechanics of the hip joint. Aimofthestudy to compare the results of using individually designed components, supportive antiprotrusion rings, augments, and hemispherical components in revision total hip arthroplasty for type IIIB bone defects according to Paprosky classification. Methods.The study analyzed the treatment outcomes of 90 patients with type IIIB bone defects who underwent revision total hip arthroplasty between 2017 and 2022. Patients were divided into three groups: the first group received individually designed acetabular components, the second group received augments with hemispheres, and the third group had antiprotrusion cages implanted. The analysis included the reasons for revision surgery, operation duration, blood loss volume, and type of revision procedure. Pain and functional outcomes were assessed with WOMAC, Harris Hip Score, and VAS scales. Results.3D-printed constructs were more frequently implanted in patients with pelvic bone dissociation. The first group showed a significantly positive dynamic in functional outcomes. Complications were diagnosed in 27 (30%) cases: joint instability (dislocation) in 10 (11.1%) patients, periprosthetic infection in 8 (8.8%), aseptic loosening in 4 (4.4%), and sciatic nerve neuropathy in 5 (5.5%) patients. The number of these complications was higher in the second and third groups of patients. Conclusion.Custom-made implants using 3D technologies are a preferable option for revision total hip arthroplasty in patients with type IIIB defects according to Paprosky classification, especially in cases of pelvic bone dissociation

Postoperative bone defects’ reconstruction in patients with focal form of chronic post-traumatic osteomyelitis

A prospective comparative analysis, i.e. the results of treatment of 68 patients, was carried out. The focal form of chronic post-traumatic osteomyelitis of the distal third of the tibia was focused. All patients were subjected to surgical debridement of the osteomyelitic focus on the variant of osteonecrectomy, followed by myoplastic reconstruction of the formed bone defect with chopped autologous muscle. In 30 patients, the traditional method of myoplastic reconstruction was used, and in 38 patients, the improved one. We added autologous Platelet-Rich Plasma (hereinafter - PRP) to the muscle graft before placing it into the bone defect. After filling in the defect, we sutured a Resorbable Collagen Membrane (hereinafter - RCM) to its edges in order to seal the defect and additionally fix the muscle graft. The dynamics of changes in the structure and the rate of fixation of the muscle graft to the walls of the bone cavity, the duration of the local inflammatory response, the duration of hospitalization, short-term outcomes, and long-term results of treatment in the comparison groups were evaluated
