A total of 30 different standards were tested, each containing 10 samples of three distinct substances: Aflatoxin B1, Deoxynivalenol, and Zearalenone. The standards were sourced from 10 different global market leading manufacturers. To facilitate comparison, all the standard sets were adjusted to the same concentration level. The standards were analyzed using the techniques LC-MS/MS, HPLC-DAD, and LC-HRMS to assess their quality attributes. Regarding the validation of the reference values, it was observed that 30% of the suppliers provided reference standards that were either below the lower acceptance limit or above the higher acceptance limit, confirmed by both the LC-MS/MS and HPLC-DAD methods. Furthermore, a total of 12 impurities were found in the DON standards, 10 in the AFB1 standards, and 8 in the ZON standards, distributed across all the suppliers. Therefore, this study suggests relevant adjustments to the ISO 17034 standard, proposing that the purity of a raw material should be uniformly based on q-NMR analysis, as most manufacturers state the purity of their certificates is determined using HPLC-UV or LC-MS/MS. Liquid standards with a shelf life of ≤1 year should not exceed an uncertainty of 3%. Standards that have a longer shelf life should not have more than 5% uncertainty. This study also emphasizes the importance of stability. The standards should undergo continuous long-term monitoring; otherwise, products may exhibit a target value of only 80%, as seen in one instance. It is also recommended to include proof of HPLC and LC-MS/MS analyses on the certificate of each released batch of a final product.}, year = {2024}, eissn = {2072-6651}, pages = {397}, orcid-numbers = {Sulyok, Michael/0000-0002-3302-0732; Szekeres, András/0000-0003-1651-4623} } @article{MTMT:35295178, title = {Tracking Varroa Parasitism Using Handheld Infrared Cameras: Is Eusocial Fever the Key?}, url = {https://m2.mtmt.hu/api/publication/35295178}, author = {Sipos, Tamás and Orsi-Gibicsár, Szilvia and Schieszl, Tamás and Donkó, Tamás and Zakk, Zsombor and Farkas, Sándor and Binder, Antal and Keszthelyi, Sándor}, doi = {10.3390/insects15090693}, journal-iso = {INSECTS}, journal = {INSECTS}, volume = {15}, unique-id = {35295178}, abstract = {The Varroa destructor is the most significant bee parasite and the greatest threat to bee health all around the world. Due to its hidden lifestyle, detection within the brood cell is only possible through invasive techniques. Enhancing detection methods is essential for advancing research on population dynamics, spread, selection efforts, and control methodologies against the mite. In our study, we employed infrared imaging to measure the thermal differences in parasite and intact Apis mellifera worker broods. Experiments were conducted over two years at the MATE Kaposvár Campus in Hungary involving five beehives in 2022 and five beehives in 2023. A FLIR E5-XT WIFI handheld infrared camera was used to create a heat map of capped brood frames. Our results indicate that the resolution of these cameras is sufficient to provide detailed IR images of a bee colony, making them suitable to detect temperature differences in intact and Varroa parasitized capped brood cells. Mite parasitism causes a time-dependent and sustained temperature increase in developing bee pupae, observable regardless of mite number. Our work demonstrates two different heating patterns: hotspot heating and heating cells that are responsible for the elevated temperature of the Varroa-infested cells as a social fever response by the worker bees. Based on our results, future research combined with AI-based image evaluation software could offer beekeepers and researchers practical and valuable tools for high-throughput, non-invasive Varroa detection in the field.}, keywords = {Apis mellifera; Infrared thermography; Social immunity; Varroosis}, year = {2024}, eissn = {2075-4450}, orcid-numbers = {Sipos, Tamás/0000-0003-2569-2720; Orsi-Gibicsár, Szilvia/0000-0001-6154-3330; Donkó, Tamás/0000-0003-3276-3347; Keszthelyi, Sándor/0000-0001-7966-1001} } @article{MTMT:35200658, title = {Correlation Analysis among the Various Inbreeding Coefficients of Pannon Ka Rabbits}, url = {https://m2.mtmt.hu/api/publication/35200658}, author = {Nagy, István and Bokor, Árpád and Farkas, János and Nguyen, Anh Thi and Posta, János and Kövér, György}, doi = {10.3390/d16090524}, journal-iso = {DIVERSITY-BASEL}, journal = {DIVERSITY (BASEL)}, volume = {16}, unique-id = {35200658}, abstract = {In a closed population with a limited population size, mating of related animals is unavoidable. In this study, the genealogy data of a synthetic maternal rabbit breed called Pannon Ka were used to calculate different inbreeding coefficients. The evaluated animals were born between 1995 and 2020, and the pedigree consisted of 5819 animals that originated from 4205 rabbit does and from 1314 rabbit bucks. The pedigree was further extended with 16,013 dummy progeny records in order to calculate litter inbreeding coefficients. Besides the conventional Wright inbreeding coefficients, the so-called ancestral and new inbreeding coefficients were also calculated using the gene dropping method. By the end of the evaluated period, the litter inbreeding increased to almost 11 and 60% for Wright and Ballou inbreeding, while the Kalinowski and the Kalinowski new inbreeding coefficients were 9.25 and 16.67%, respectively. Correlation coefficients were calculated for the does and for the litters. Finally, the effects of pedigree length and completeness were also taken into account using the complete generation equivalents in a partial correlation analysis. Based on the results, it could be seen that the different ancestral inbreeding coefficients had high correlation. Similarly, the conventional Wright inbreeding coefficients showed strong correlation with the new inbreeding coefficients. On the contrary, the correlation between ancestral and new inbreeding coefficients was low. Taking the complete generation equivalent into account did not give unambiguous results. It could be concluded that the different inbreeding coefficients are based on different concepts, and they are clearly different population parameters.}, keywords = {New inbreeding; Ancestral inbreeding; Pannon Ka rabbits; conventional inbreeding}, year = {2024}, eissn = {1424-2818}, orcid-numbers = {Nagy, István/0000-0003-0247-6638; Farkas, János/0000-0001-6794-854X} } @article{MTMT:35180480, title = {Effects of green human resource management practices on employee green behavior: the role of employee’s environmental knowledge management and green self-efficacy for greening workplace}, url = {https://m2.mtmt.hu/api/publication/35180480}, author = {Masum, Miah and Rahman, S.M.

Kinetic PET image analysis revealed time-activity curves with uptake maxima below 1 min in the liver, renal cortex, portal vein, lung and coarctatio aortae. In the frame of static PET image analysis, based on the standardized uptake value (SUV), the so-called metabolic liver volume (MLV, liver volume defined by over 0.9 × average liver SUV) and the total liver glycolysis (TLG, MLV multiplied by the SUVmean) were calculated. Mycotoxicosis increased total liver glycolysis (p < 0.04) after 14 days and liver tissue TLG inhomogeneity was minimal. Pearson correlation between TLG and alkaline phosphatase (ALP) was positive (0.515), while negative with LDH and AST (− 0.721 and − 0.491, respectively).
