Correlations between gaseous and liquid phase chemistries induced by cold atmospheric plasmas in a physiological buffer.

The understanding of plasma-liquid interactions is of major importance, not only in physical chemistry, chemical engineering and polymer science, but in biomedicine as well as to better control the biological processes induced on/in biological samples by Cold Atmospheric Plasmas (CAPs). Moreover, plasma-air interactions have to be particularly considered since these CAPs propagate in the ambient air. Herein, we developed a helium-based CAP setup equipped with a shielding-gas device, which allows the control of plasma-air interactions.

The effect of time of day on cold water ingestion by high-level swimmers in a tropical climate.

The authors tested the effect of cold water ingestion during high-intensity training in the morning vs the evening on both core temperature (TC) and thermal perceptions of internationally ranked long-distance swimmers during a training period in a tropical climate. Nine internationally ranked long-distance swimmers (5 men and 4 women) performed 4 randomized training sessions (2 in the evening and 2 in the morning) with 2 randomized beverages with different temperatures for 3 consecutive days. After a standardized warm-up of 1000 m, the subjects performed a standardized training session that consisted of 10 x 100 m (start every 1'20″) at a fixed velocity.

Red blood cell deformability and aggregation, cell adhesion molecules, oxidative stress and nitric oxide markers after a short term, submaximal, exercise in sickle cell trait carriers.

The present study investigated the hemorheological and endothelial alterations in sickle cell trait (SCT) carriers in response to a submaximal exercise. Eleven SCT carriers and 11 subjects with normal hemoglobin performed submaximal exercise for 15 min. Blood was sampled at rest, at the end of exercise, and at 2 and 24 h of recovery.

Patterns of exercise-related inflammatory response in sickle cell trait carriers.

Objective: To clarify whether sickle cell trait (SCT) carriers (SCT group) present a specific postexercise inflammatory response to repeated and strenuous exercise.

Design: The patterns of inflammatory markers in response to repeated heavy exercise were investigated in SCT carriers (SCT group: eight men, 20.0+/-0.

Cardiorespiratory responses during three repeated incremental exercise tests in sickle cell trait carriers.

This study investigated the cardioventilatory responses during heavy exercise in sickle cell trait carriers (SCTc) and subjects with normal hemoglobin (control group). Eight SCTc and six control subjects repeated three incremental exercise tests (Iet) separated by 10-min recoveries. Cardioventilatory parameters were analyzed at rest and during the first and third Iet.

Effects of short supramaximal exercise on hemorheology in sickle cell trait carriers.

This study compared the hemorheological profile at rest and in response to a short supramaximal exercise test between sickle cell trait (SCT) carriers and a control group. Eight SCT carriers and eight control subjects performed a ramp exercise test on a cycle ergometer conducted to maximal oxygen uptake (VO2max). One week later, they performed a supramaximal exercise test consisting of pedaling for 1 min at 110% VO2max.
