The concepts of irreversibility and reversibility in research on anthropogenic environmental changes.

The concept of "irreversibility" and its counterpart "reversibility" have become prominent in environmental and ecological research on human-induced changes, thresholds, climate tipping points, ecosystem degradation, and losses in the cryosphere and biosphere. Through a systematic literature review, we show that in these research fields, these notions are not only descriptive terms, but can have different semantic functions and normative aspects. The results suggest that, in the context of environmental and ecological research the concepts of irreversibility and reversibility have taken on additional usages in comparison to their contexts in theoretical thermodynamics and mechanics.

The historical appreciation of tea dates back to ancient times, while technological limitations have long hindered in-depth exploration of its flavor complexity and functional attributes. This study investigated the effects of various teas on a traditional delicacy, "tea-flavored fish", using teas processed via traditional methods. Analysis of functional components revealed that processing and fermentation reduced catechin levels (186.

It argues that libertas scholastica (the corporate freedom of the universities) and libertas philosophandi (liberty of philosophizing, within and without the universities) were distinctive guiding concepts, sometimes in opposition but occasionally complementary, in debates over the universities in this period. If these two notions together constitute the antecedents of the modern concept of academic freedom, their conjunction must be recognized as a much more contingent and irregular phenomenon than has been previously understood.

Purpose: To examine the effects of physical activity on college students' social physique anxiety and the mediating and moderating roles of negative physical self and mental toughness in it, and to provide empirical evidence that physical activity improves college students' social physique anxiety.
Methods: Stratified whole cluster convenience sampling was used to survey 1177 university students, 53.8% male and 46.
Oxytocin levels in response to CRH administration in hypopituitarism and hypothalamic damage: a randomized, crossover, placebo-controlled trial.
Sci Rep

Increasing evidence supports the presence of oxytocin deficiency (OXT-D) in patients with hypopituitarism and hypothalamic damage (HHD), that might be associated with neuropsychological deficits and sexual dysfunction, leading to worse quality of life (QoL). Therefore, identifying a provocative test to diagnose an OXT-D will be important. Corticotropin-releasing hormone (CRH) is a candidate for such a test as it increases oxytocin secretion in animal models.
