Comparison of Aerobic and Muscular Power Between Junior/U23 Slalom and Sprint Paddlers: An Analysis of International Medalists and Non-medalists.

This study aimed to compare the aerobic power (treadmill running) and muscle power (bench press and bench pull) of Junior/U23 paddlers from Slovakia who won medals in international championships with that of those who did not take the podium. Forty-three Slovak Junior/U23 paddlers (sprint = 24, medalists = 8, non-medalists = 16; slalom = 19, medalists = 11, non-medalists = 8) were tested in 2018 and 2019 after the world championships. The maximal oxygen uptake (VO) and the velocity at maximal oxygen uptake (vVO) were determined by the incremental running protocol (0% slope and 1 km⋅h increments every minute until volitional exhaustion).

Expression profile of human porcine endogenous retrovirus A receptors (HuPAR-1, HuPAR-2) and transcription factor activator protein-2γ (TFAP-2C) genes in infected human fibroblasts-Model in vitro.

Background: Xenotransplantation of porcine tissues raises concerns, especially in the context of the potential interspecies transmission of porcine endogenous retroviruses (PERVs). To date, the possibility of PERV infections of various human cells has been confirmed in vitro. PERVs infect cells coupling viral Env protein with adequate functional receptor on the surface of the host cell.

Road to the Olympics: physical fitness of medalists of the Canoe Sprint Junior European and World Championship events over the past 20 years.

Background: In this article we aimed to find out whether there is a difference in physiological, anthropometric and power variables between medalists in junior international Championship events (MJCH) and the remaining members of the national team (NT) in flat water canoe sprint.

Methods: Sixty male junior kayakers from Slovak NT were tested annually between years 1995 and 2016. Sixteen of them won at least one medal (gold, silver or bronze) at junior international Championship.

[Residual clubfoot correction by means of lateral cuboid resection].

The paper presents the late results (after 5-16 years; mean follow-up--9.5 years) of lateral cuboid resection performed in 55 children with pathologic foot adduction. The age of the children ranged from 18 months to 12 years (average age 41 months).
