PURPOSE To investigate how different warm-ups influenced subsequent sled-pull sprint performance in Olympic-level bob-skeleton athletes as part of their preparation for the 2010 Winter Olympics. METHODS Three female and 3 male athletes performed 5 different randomized warm-ups of differing intensities, durations, and timing relative to subsequent testing, each 2 days apart, all repeated twice...

PURPOSE Undifferentiated pleomorphic sarcoma (UPS) is defined as a sarcoma with cellular pleomorphism and no identifiable line of differentiation. It is typically a high-grade lesion with a metastatic rate of about one third. No tumor-specific rearrangement has been identified, and genetic markers that could be used for treatment stratification are lacking. We performed transcriptome sequencing...

Background. Regardless of the age, elite athletes exhibit various motor capabilities (e.g., speed; endurance; strength) that are specific to that particular sport. Objectives. The purpose of this study was to compare different aspects of physical fitness (agility, strength, endurance) in thirty, 9 year old elite soccer and hockey players. Methods. Participants completed a 90 minute familiariz...

SKN-1, the Caenorhabditis elegans Nrf1/2/3 ortholog, promotes both oxidative stress resistance and longevity. SKN-1 responds to oxidative stress by upregulating genes that detoxify and defend against free radicals and other reactive molecules, a SKN-1/Nrf function that is both well-known and conserved. Here we show that SKN-1 has a broader and more complex role in maintaining cellular stress de...

Aim: To verify the effects of a 2-week high-intensity interval training (HIIT) on physical performance in young female athletes. Methods: rugby players (n = 13; 15.92 ± 0.76 years old) participated an 8-session HIIT supervised through online video calls for two weeks. They were evaluated pre- and post-HIIT 3-min burpees, 1-min sit-ups, maximum push-ups, squats. Perceptions related to protocols ...

introduction: acute pain and swelling following endodontic treatment are challenges for patients and dentists. according to previous studies, the incidence of flare-ups increases after endodontic treatment of teeth with necrotic pulp. calcium hydroxide is currently used as a multipotential medicament in root canal therapy. the aim of this study was to evaluate the incidence and severity of flar...
