    Abstract The comprehensive description of a country’s family name stock has been, and is being, carried out in several European countries, including Hungary. The paper, from among other possible lines of research, offers a typological-statistical survey of the Hungarian family name stock. The study focuses on the 100 most frequent family names of contemporary Hungary, while taking international research (European Surname Typology Project) into account and drawing its conclusions from complete or highly representative name corpora. The paper discusses the typological distribution of the 100 most frequent contemporary family names in Hungary, in comparison with Hungarianhistorical family names from the beginning of the 18th century, as well as types of art ificial Hungarian family names produced in the processes of official family name changes in the 19–20th centuries. Certain peculiarities of Hungarian family names are also pointed out when compared to the family names of other languages and countries. The paper also focuses on some questions of research methodology that arise in the field and are rarely discussed in relevant international literature. Different approaches in research methodology are described with their consequences, i.e. differences in research results. Ultimately, the paper intends, in part, to give a picture of the Hungarian family name stock and the possibilities of further research in the field, while also exposing a number of ideas that should also be taken into consideration by international research projects of great importance.

    Abstract The accumulation of organophosphorus type herbicides has been observed worldwide in the environment (i.e. soil, water), together with their appearance in foods of plant origin. This paper reports a new liquid chromatography–isotope dilution–tandem mass spectrometric method (LC-IDMS) for the analysis of glufosinate (GLUF), glyphosate (GLY) and its main metabolite, aminomethylphosphonic acid (AMPA), in challenging food samples. Sample preparation is based on aqueous extraction with ethylenediaminetetraacetic acid solution, followed by solid-phase extraction (SPE) on mixed-mode cation exchange cartridges to remove matrix constituents before derivatization with 9-fluorenylmethoxycarbonyl chloride (FMOC-Cl). Derivatized samples were cleaned up on hydrophilic modified polymeric SPE cartridge. This two-step SPE supported sample preparation approach, and the LC-IDMS separation carried out in negative ionization mode resulted in fit-for-purpose recovery (81–118%) and precision (4–18%) in the validation of glutamate loaded spice mix, mushroom, maize and cherry samples. Amino acid content influencing FMOC derivatization efficiency was estimated with a HILIC-MS/MS setup. Multiple reaction monitoring (MRM) was assisted with high-resolution (QTOF) accurate mass data on the FMOC-derivatized GLUF, GLY and AMPA standards. The limit of quantification (LOQ) was 0.005 mg/kg for all the three analytes. The method was successfully applied on quality control samples (oat and arugula) with fit-for-purpose accuracy (99–120%) and on other nineteen real samples, where GLY and AMPA were detected in the range between 0.005 and 0.069 mg/kg.

    Abstract The aim of the experiment was to investigate the use and effect of a new beak-abrasive material not yet examined on mortality of non-beak trimmed laying hens of different genotypes housed in an alternative pen. The study was performed on 636 females belonging to three genotypes of Bábolna TETRA Ltd. (a1 = commercial brown layer hybrid (C); a2 = purebred male line offspring group (maternal); a3 = purebfigure ed female line offspring group (paternal)). A total of 318 hens, i.e., 106 hens/genotype distributed in six pens (53 hens/pen), were evaluated. Cylindrical beak-abrasive blocks of 5.3–5.6 kg were suspended (0.1–0.4 mm diameter gravel, limestone grit, lime hydrate, and cement mixture) in six alternative pens. In six control pens without abrasive material, 318 hens, i.e., 106 hens/genotype (2 pens control group/genotype, i.e., C1 = commercial brown layer hybrid, C2 = purebred male line offspring group, C3 = purebred female line offspring group; 53 hens/pen;) were placed where there were no beak-abrasive materials. The rate of change in the weight of the beak-abrasive materials and the mortality rate were recorded daily. In the six pens equipped with beak-abrasive materials, infrared cameras were installed, and 24 h recordings were made. The number of individuals pecking the beak-abrasive material, the time and duration of dealing with the material were recorded. Data coming from one observation day are given. During the 13 experimental weeks of observation, the weight loss of beak-abrasives differed significantly in the different genotypes (a1 = 27.4%; a2 = 29.6%; a3 = 56.6%). During the only day analyzed, the hens from all the genotypes mostly stayed between 17:00 and 21:00 h in the littered scratching area where the beak-abrasive material was placed (a1 = 48.4%; a2 = 49.2%; a3 = 54.4%). In the case of each genotype, the rate of the hens dealing with beak-abrasives in the first two periods of the day was relatively low (0.2%–0.7%). Peaks of the activity were between 17:00 and 21:00 (a1 = 0.8%; a2 = 1.3%; a3 = 1.8%). The a3 dealt with the beak-abrasive materials to a significantly greater extent in the period from 13:00 to 17:00 (0.8%) and from 17:00 to 21:00 (1.8%) than the a1 (0.2% and 0.8%, respectively). Due to the use of the beak-abrasive materials, the mortality rate decreased the most in the genotypes that used them (a1 with beak-abrasive material 0.0% vs. C1 9.4%; a2 with beak-abrasive material 2.9% vs. C2 12.4%; a3 with beak-abrasive material) 15.4% vs. C3 5.7%). It can be concluded that the insertion of beak-abrasive materials increased the behavioral repertoire of hens, which is particularly beneficial from an animal welfare point of view. Further and longer-term research is needed to determine whether the insertion of the beak-abrasive material has a beneficial effect on the mortality data of the experimental groups through enrichment, either through physical abrasion of the beak or both.

    Abstract The synaptogenic hypothesis of major depressive disorder implies that preventing the onset of depressive-like behavior also prevents the loss of hippocampal spine synapses. By applying the psychoactive drugs, diazepam and fluoxetine, we investigated whether blocking the development of helpless behavior by promoting stress resilience in the rat learned helplessness paradigm is associated with a synaptoprotective action in the hippocampus. Adult ovariectomized and intact female Sprague-Dawley rats (n = 297) were treated with either diazepam, fluoxetine, or vehicle, exposed to inescapable footshocks or sham stress, and tested in an active escape task to assess helpless behavior. Escape-evoked corticosterone secretion, as well as remodeling of hippocampal spine synapses at a timepoint representing the onset of escape testing were also analyzed. In ovariectomized females, treatment with diazepam prior to stress exposure prevented helpless behavior, blocked the loss of hippocampal spine synapses, and muted the corticosterone surge evoked by escape testing. Although fluoxetine stimulated escape performance and hippocampal synaptogenesis under non-stressed conditions, almost all responses to fluoxetine were abolished following exposure to inescapable stress. Only a much higher dose of fluoxetine was capable of partly reproducing the strong protective actions of diazepam. Importantly, these protective actions were retained in the presence of ovarian hormones. Our findings indicate that stress resilience is associated with the preservation of spine synapses in the hippocampus, raising the possibility that, besides synaptogenesis, hippocampal synaptoprotection is also implicated in antidepressant therapy.

    Abstract 822

    826

    Multifunctional laser technology integrates different laser processes in one manufacturing cell to meet the demand for agile production technology. A processing head was developed and put into operation mastering cutting, joining and additive manufacturing steps without tool change. Parallel development of a digital twin of the entire system aims at the acceleration and optimization of the engineering of the robot cell up to its virtual commissioning. This approach enabled the first realization of a multifunctional laser robot cell and its digital twin. Virtual commissioning accelerated the design and optimization of mechanics and control as well as the programming of the production cell. The multifunctional approach saves numerous single production steps and, hence, leads to a significant shortening of manufacturing lines utilizing the full flexibility of the tool laser beam. Virtualization enables accelerated commissioning of the entire system, significantly reduced susceptibility to errors in production preparation and more efficient production planning.

    Abstract Kynurenic acid (KYNA), a metabolite of tryptophan, as an excitatory amino acid receptor antagonist is an effective neuroprotective agent in case of excitotoxicity, which is the hallmark of brain ischemia and several neurodegenerative processes. Therefore, kynurenine pathway, KYNA itself, and its derivatives came into the focus of research. During the past fifteen years, our research group has developed several neuroactive KYNA derivatives, some of which proved to be neuroprotective in preclinical studies. In this study, the synthesis of these KYNA derivatives and their evaluation with divergent molecular characteristics are presented together with their most typical effects on the monosynaptic transmission in CA1 region of the hippocampus of the rat. Their effects on the basic neuronal activity (on the field excitatory postsynaptic potentials: fEPSP) were studied in in vitro hippocampal slices in 1 and 200 μM concentrations.

    Abstract The experiment was carried out with altogether 1740 non-beak-trimmed laying hens, which originated from Bábolna TETRA Ltd., representing two different types (Rhode Island Red (RIR) and Rhode Island White (RIW)) and four different lines (Lines 1-2: RIR, Lines 3-4: RIW). The plumage and body condition of randomly selected 120 hens (30 hens/line) was examined at 20, 46, and 62 weeks of age. The egg production and the mortality of the sampled hens were recorded daily. Based on the results, it was established that the lines differ clearly in most of the examined traits. It was also pointed out that injurious pecking of the hens resulted not only in damages in the plumage but also in the body condition. The results obviously demonstrated that the highest egg production and the lowest mortality rate were reached by those hens, which had the best plumage and body condition. Because the occurrence of injurious pecking seems to depend on the genetic background, selection of the hens (lines, families, individuals) for calm temperament will be very important in the future in order to maintain the high production level in non-beak-trimmed layer flocks.

    Abstract Absolute Lymphocyte Count (ALC) has been recently established as a prognostic factor of survival in pediatric Acute Lymphoblastic Leukemia (ALL). A retrospective analysis of 132 patients treated according the BFM - ALLIC 2002 protocol was performed in a single institution. A possible association between ALC values and Overall Survival (OS) or Event-Free Survival (EFS) was evaluated at multiple time points during induction chemotherapy. ALC higher than 350 cells/μL measured on the 33th day of induction was associated with better Overall- and Event-Free Survival in both Kaplan-Meier (OS 88.6% vs. 40%; p < 0.001 / EFS 81.6% vs. 30%; p < 0.001) and Cox regression (OS HR 8.77 (3.31-23.28); p < 0.001) and EFS HR 6.61 (2.79-15.63); p < 0.001) analyses. There was no association between survival and measured ALC values from earlier time points (day of diagnosis, days 8 and 15) of induction therapy. Patients with low ALC values tend to have higher risk (MR or HR groups) and a higher age at diagnosis (>10 years). With help of day 33 ALC values of 350 cells/μL cutoff it was possible to refine day 33 flow cytometry (FC) Minimal Residual Disease (MRD) results within the negative cohort: higher ALC values were significantly associated with better survival. ALC on day 33 (350 cells/μL) remained prognostic for OS and EFS in multivariate analysis after adjusting it for age, cytogenetics, immunophenotype and FC MRD of induction day 33. According to these findings ALC on day 33 of induction is a strong predictor of survival in pediatric ALL.
