Testosterone/cortisol ratio: gender effect and prediction of podium results in beach sprint master rowers.

Objective: The purpose of this study was to address the lack of data on the stress and motivation response in master athletes during competitions, as athletic performance in this age group can be significantly impacted by stress rather than appropriate training.

Methods: Coastal rowing beach sprint master athletes aged 43-57 years were examined to assess the saliva levels of stress biomarkers, cortisol, and testosterone. Specifically, samples were collected at awakening and before and after the boat race.

A case report on dietary needs of the rowing athlete winner of the triple crown.

Sports nutrition is a topic that is often misinterpreted and sometimes abused. The often-used "shot-gun" method to meeting caloric needs by simply increasing caloric intake disregarding nutrient source is scientifically contrary to the need for a more careful study of the nutritional requirements of rowers. Rowing by itself is a very demanding sport as typical training sessions use exercise intensities that range from very low submaximal work to short term supramaximal efforts.

Unveiling MOF-808 photocycle and its interaction with luminescent guests.

The world of metal-organic frameworks (MOFs) has become a hot topic in recent years due to the extreme variety and tunability of their structures. There is evidence of MOFs that exhibit intrinsic luminescence properties that arise directly from their organic components or from the interaction between them and metallic counterparts. A new perspective is to exploit the porous nature of MOFs by encapsulating luminescent guests, such as organic dyes, in order to explore possible changes in the luminescence activity of the combined systems.

Effects of Physical Exercise and Motor Activity on Depression and Anxiety in Post-Mastectomy Pain Syndrome.

Background: Chronic post-surgical pain is a condition persisting for not less than 3 months after surgical intervention. It is evaluated that 25-60% of women who underwent breast cancer excision suffer from post-mastectomy pain syndrome, and anxiety, depression, sleep disturbance, and catastrophizing. Physical activity can reduce the risk of chronic diseases and has a good impact on mood and cognitive function.

COVID-19 after 2 Years from Hospital Discharge: A Pulmonary Function and Chest Computed Tomography Follow-Up Study.

Introduction: Serial follow-up with pulmonary function testing (PFT) and chest computed tomography (CT) after severe COVID-19 are recommended. As a result, many longitudinal studies have been published on COVID-19 of different grade of severity up to 1-year follow-up. Therefore, we aimed at a long-term observational study throughout 2 years after severe COVID-19.
