Abstract

Background

Exhausting exercise induces muscle damage associated with high production of free radicals and pro-inflammatory mediators.

Aim

The objective of this study was to determine for the first time and simultaneously whether oral coenzyme Q10 (CoQ10) supplementation can prevent over-expression of inflammatory mediators and oxidative stress associated with strenuous exercise.

Methods

The participants were classified in two groups: CoQ10 group (CG) and placebo group (PG). The physical test consisted in a constant run (50 km) that combined several degrees of high effort (mountain run and ultra-endurance), in permanent climbing.

Results

Exercise was associated with an increase in TNF-α, IL-6, 8-hydroxy-2′-deoxyguanosine (8-OHdG), and isoprostane levels, revealing the degree of inflammation and oxidative stress induced. Oral supplementation of CoQ10 during exercise was efficient reducing oxidative stress (decreased membrane hydroperoxides, 8-OHdG and isoprostanes generation, increased catalase, and total antioxidant status), which would lead to the maintenance of the cell integrity. Data obtained also indicate that CoQ10 prevents over-expression of TNF-α after exercise, together with an increase in sTNF-RII that limits the pro-inflammatory actions of TNF. Moreover, CoQ10 supplementation reduced creatinine production.

Conclusions

CoQ10 supplementation before strenuous exercise decreases the oxidative stress and modulates the inflammatory signaling, reducing the subsequent muscle damage.

In der MONARCHE-3-Studie lebten Frauen mit fortgeschrittenem Hormonrezeptor-positivem, HER2-negativem Brustkrebs länger, wenn sie zusätzlich zu einem nicht steroidalen Aromatasehemmer mit Abemaciclib behandelt wurden; allerdings verfehlte der numerische Zugewinn die statistische Signifikanz.

ADT zur Radiatio nach Prostatektomie: Wenn, dann wohl länger

Welchen Nutzen es trägt, wenn die Strahlentherapie nach radikaler Prostatektomie um eine Androgendeprivation ergänzt wird, hat die RADICALS-HD-Studie untersucht. Nun liegen die Ergebnisse vor. Sie sprechen für länger dauernden Hormonentzug.

„Überwältigende“ Evidenz für Tripeltherapie beim metastasierten Prostata-Ca.
