(1) Background: Trainers and athletes have always sought to reduce the failure of muscle function during long endurance events. However, nowadays, it is a topic that is generating much debate in the scientific field. Currently, deep-sea water (DSW) intake seems to be a suitable hydration alternative for this type of endurance event. Therefore, the aim of this study was to determine whether DSW consumption during a triathlon event could preserve muscle function after exercise. (2) Methods: Nineteen trained male triathletes (age = 39.0 ± 4.25 years; BMI = 23.67 ± 1.81 kg/m²) randomly performed three triathlons, one of them consuming DSW (Totum SPORT 30 AB, Laboratories Quinton International, S.L., Spain), the other consuming isotonic placebo and the last with tap water-hydration. A vertical jump test with countermovement and an isometric muscle strength test were conducted before and after the triathlon test. (3) Results: There was a significant difference between treatment × time during the isometric muscle strength test. Based on the Tukey post hoc analysis, the peak net force decreased statistically in the placebo (p = 0.045) and control conditions (p = 0.026), but not in the experimental condition (p = 0.121). In addition, all of the conditions studied obtained similar results in the countermovement vertical jump after exercise. (4) Conclusions: As a result, consumption of DSW seems to delay the failure of muscle function specifically in isometric exercises but does not improve performance in sports. Thus, DSW does not alter muscle capacity in a negative way; therefore, its consumption may be recommended. Full article

Platelets play a significant role in hemostasis and perform essential immune functions, evidenced by the extensive repertoire of antimicrobial molecules. Currently, there is no clear description of the presence of azurocidin in human platelets. Azurocidin is a 37 kDa cationic protein abundant in neutrophils, with microbicidal, opsonizing, and vascular permeability-inducing activity. Therefore, this work aimed to characterize the content, secretion, translation, and functions of azurocidin in platelets. Our results show the presence of azurocidin mRNA and protein in α-granules of platelet and megakaryoblasts, and stimulation with thrombin, ADP, and LPS leads to the secretion of free azurocidin as well as within extracellular vesicles. In addition, platelets can translate azurocidin in a basal or thrombin-induced manner. Finally, we found that the addition of low concentrations of azurocidin prevents platelet aggregation and activation. In conclusion, we demonstrate that platelets contain, secrete, and translate azurocidin, and this protein may have important implications for hemostasis. Full article

The technological challenges of the so-called fourth industrial revolution, innovative inter-organizational network relations, integration in corporate strategies of sustainability challenges, or unsatisfactory levels of staff commitment stemming from complexity and related uncertainty are some of the main key issues that organizations have to face in the near future. In this context, the appearance of the ‘evolutionary organization’ model marks an important milestone in terms of a renewed identification of fundamental principles for organizations, arguably as an update or revision of systemic thinking. This model allows organizations, functioning as living beings, to be more agile and humanistic and better prepared to establish agile and trustworthy inter-organizational relationships. Collaborative platforms are possible from that ability to add value between organizations while also being closely aligned with the principles and values of evolutionary organizations. The purpose of this paper is to provide insights into how these (teal) organizations work with respect to their common principles of wholeness, evolutionary purpose, and self-management. In the end, the study intends to highlight relevant practical organizational aspects that can better facilitate the management of current and increasing complexity, as well as the transition to more humanistic-oriented organizations.
