Return-to-Play Timeline and Recovery Predictors After COVID-19 Infection in Elite Football Players

Zsolt Szelid Zsuzsanna Kives Ágnes Sziva

Publication Name: Sports

Publication Date: 2025-05-01

Volume: 13

Issue: 5

Page Range: Unknown

Description:

The pandemic period significantly impacted professional football, leading to mandatory SARS-CoV-2 testing and quarantine. Our study aimed to examine the factors influencing time of recovery after a positive test, including return-to-training (RTT) and return-to-first-match (RTFM) of male football players in a first-division Hungarian team between 8 May 2020 and 30 June 2022. Infection was determined using mandatory RT-PCR testing 3 times per week, which later decreased to 1 to 2 times per week, in 55 elite players. A self-administered questionnaire was utilized based on the U.S. Department of Health and Human Services symptom list and modified with relevant factors of return-to-play in football. The incidence of SARS-CoV-2-positive players in the three consecutive years was 5.26; 21.43 and 45.71%. Mild symptoms were present in test-positive players, completing the questionnaire (n = 31), predominantly loss of smell and dry cough. Post-infection fatigue levels correlated with the perceived performance decline. In players with precisely documented dates (n = 18), the average RTT was 18.7 days, while the RTFM was 67.3 days. Older players returned to training faster than their younger counterparts and the RT-PCR Ct number had a weak negative correlation with RTFM. Mental support was provided by family and friends in 68% of the players. This study highlights the variability in return-to-play timelines and the role of age, symptom severity and mental help in recovery and emphasizes the need for individualized rehabilitation in elite football.

Description of three new bat-associated species of hard ticks (Acari, Ixodidae) from Japan

Ai Takano Jenő Kontschán Hiroshi Shimoda Yasuhiro Gotoh Dávid Kováts Mamoru Takahashi Vuong Tan Tu Junko Mizuno Michio Natsume Sándor Hornok Takeo Yamauchi

Publication Name: Zookeys

Publication Date: 2023-01-01

Volume: 1180

Issue: Unknown

Page Range: 1-26

Description:

In Eurasia, the geographically most widespread ixodid tick species of the bat families Rhinolophidae Gray, Vespertilionidae Gray, and Miniopteridae Dobson were considered to belong to four species, Ixodes vespertilionis Koch, I. collaris Hornok, I. ariadnae Hor-nok, and I. simplex Neumann. Previous data attest that bat-associated tick species from Eastern Asia show remarkable genetic difference from the above four tick species, but in the absence of detailed morphological comparison these were regarded as conspe-cific. In this study we compensate for this lack of data on three bat-associated tick spe-cies, reporting their morphological comparison, as well as molecular and phylogenetic relationships. According to the results we describe the females of three tick species new to science, i.e., I. nipponrhinolophi Hornok & Takano, sp. nov., I. fuliginosus Hornok & Takano, sp. nov., and I. fujitai Hornok & Takano, sp. nov. In case of all three new tick species the cytochrome c oxidase subunit (coxI) gene showed remarkably high sequence differences from the species that they previously were thought to belong to, well exceed-ing the average limit delineating ixodid tick species. This, as well as observed morphological differences fully justify their taxonomical status as new species.

Heat radiation effects on insulating materials used in buildings

F. Hajdu Rajmund Kuti Gabriella Lászlo

Publication Name: Pollack Periodica

Publication Date: 2021-12-31

Volume: 16

Issue: 3

Page Range: 108-113

Description:

In recent years, in order to increase the energy efficiency of older buildings in Hungary, several tenders have supported the modernization of the thermal insulation. Various thermal insulation materials have been installed on walls, on slab and on floor. Unfortunately there are cases where thermal insulation materials are not installed in accordance with the construction permit or the manufacturer's instructions, which poses a serious danger in case of a fire. During the research the effects of heat on the behavior of Expanded PolyStyrene, a thermal insulation material often used in Hungary is examined. Laboratory tests and computer simulations were carried out, which are presented in detail in this paper. The aim of the research is to contribute to increase the fire safety of buildings.

How to regulate forensic familial DNA searching in Hungary?

Mónika Nogel

Publication Name: Forensic Science International Genetics Supplement Series

Publication Date: 2022-12-01

Volume: 8

Issue: Unknown

Page Range: 136-137

Description:

Forensic DNA analysis has the potential to provide useful information for criminal justice even in cases where there is no match, neither between the DNA profile generated from the crime scene and the existing DNA profiles in criminal databases, nor between the DNA collected at a crime scene and potential suspects. In contrast to traditional forensic genetic testing, forensic familial DNA searching does not provide evidence, but helps to generate investigative leads and narrow down the range of potential offenders. The aim of this study is to examine, whether there is a need for special regulation of this topic in Hungary.

Publication Name: 9th IEEE International Conference on Cognitive Infocommunications Coginfocom 2018 Proceedings

Publication Date: 2018-07-02

Volume: Unknown

Issue: Unknown

Page Range: 355-360

Description:

In recent years the strong potential behind VR and AR technologies in supporting education has become increasingly clear. From an educational perspective, an important benefit brought about by such technologies is that they lead to a teaching environment that is first and foremost learner centered. This encourages the application of innovative educational methods and introduces new modes of teaching into the learning experience. However, all of this makes it necessary for teachers to spend more time preparing for their classes, as well as growing acquainted with the latest technologies - in short, it is a process that requires improved digital literacy on the teachers' part.This paper presents an experiment contrasting traditional 2D interfaces and the MaxWhere 3D VR educational platform in order to shed light on how these technologies influence the effectiveness of various operations and workflows constituting teachers' tasks. In the experiment, the same workflow is compared when executed using e-mail attachments, a classical 2D e-learning platform and MaxWhere's 3D platform.The results of the experiment, evaluated in terms of a newly proposed (and clearly motivated) framework, point to the conclusion that when using MaxWhere instead of traditional 2D interfaces, teachers, lecturers and trainers are able to accomplish the same digital workflows with 37-64% less user operations, and up to 72% less machine operations. Based on these results, the paper concludes that MaxWhere as an educational platform offers users - not only students, but the lecturers, teachers and trainers too- a number of ways to accomplish tasks that would otherwise require extremely complicated digital workflows in more traditional 2D environments.

Diffusion in electrodes used for resistance spot welding of galvannealed steel

Martha P. Guerrero-Mata Patricia Zambrano Imre Felde Mihaly Réger Maribel De La Garza Tamás Réti Rafael Colas

Publication Name: Defect and Diffusion Forum

Publication Date: 2010-01-01

Volume: 297-301

Issue: Unknown

Page Range: 300-307

Description:

A study was carried out on Zr-Cr bearing copper electrodes used for resistance spot welding of galvannealed steel strips. One electrode exhibited a series of well-defined layers in which Zn diffused to form β- and γ-brasses; an external layer containing iron was detected in this electrode. Another electrode that exhibited a high degree of damage did not exhibited continuous Zn-diffusion layers in all places, moreover, the Fe-containing layer was either removed, or had it grown to a high extent in some places; the occurrence of Cu-rich particles embedded within the Fe containing layer was observed. Multiple cracks were observed within the γ brass layer in both electrodes. The difference in the observed behaviour of the electrodes can be attributed to a difference in the characteristics of the galvannealed coating of the strips, as the first electrode was used to weld strips in which the layer corresponding to the γ phase was well developed, whereas the second electrode was used to weld strips with only an incipient layer. It can be concluded that growth of the γ phase changes the thermophysical properties of the zinc coating, affecting the temperature profile during spot welding. © (2010) Trans Tech Publications.

Investigation of the Effect of a New Type of Copper–Sucrose Complex Compound on the Yield and Quality Parameters of Winter Wheat (Triticum aestivum L.)

Pál Szakál Balázs Ásványi Renato Kalocsai Viktoria Vona Zoltán Varga Judit Molnár Eduard Gubó Dávid Vasas Tamás Szakál Erika Krániczné Mayer Zsolt Giczi

Publication Name: Agronomy

Publication Date: 2025-07-01

Volume: 15

Issue: 7

Page Range: Unknown

Description:

We conducted experiments on winter wheat grown in copper-deficient soil, where soil tests revealed a more pronounced deficiency in the deeper layers. As climate change reduces precipitation, plants increasingly rely on nutrients from these deeper layers. A copper–sucrose complex—previously unused in agriculture—was applied as a foliar spray during the tillering and flowering stages. Across the three-year average, significant increases were observed starting from the 1 kg ha−1 copper dose in yield, from 0.3 kg ha−1 in crude protein content, and from 0.5 kg ha−1 in wet gluten content compared to the untreated control. For all three parameters, the highest values were achieved with the 2 kg ha−1 dose. Yield increased by 1.03 t ha−1, crude protein by 0.9%, and wet gluten by 2.3% relative to the control. In 2019, high humidity and favorable temperatures during flowering led to fungal infections in control plots, with DON toxin concentrations exceeding the regulatory safety threshold. Following copper–sucrose complex application, DON levels dropped below this threshold, demonstrating a measurable protective effect.
