AbstractWhile the quantity of sustainability governance initiatives and systems has increased dramatically, crises persist over whether specific governance systems can be trusted as legitimate regulators of the sustainability of economic activities. This paper focuses on conceptual tools to improve our understanding of these crises as well as the facilitating factors and barriers for sustainability governance to play a role in transitioning to profoundly more sustainable societies than those that currently exist. Bioenergy is used throughout the paper as an example to aid contextually in understanding the theoretical and abstract arguments. We first define eight premises upon which our argumentation is developed. We then define sustainability, sustainability transition, legitimacy, and trust as a premise for obtaining effectiveness in communication and minimising risks associated with misunderstanding key terms. We proceed to examine the literature on “good governance” in order to reflect upon what defines "good sustainability governance" and what makes governance systems successful in achieving their goals. We propose input, output, and throughput legitimacy as three principles constituting “good” sustainability governance and propose associated open-ended criteria as a basis for developing operational standards for assessing the quality of a sustainability governance system or complex. As sustainability governance systems must develop to remain relevant, we also suggest an adaptive governance model, where continuous re-evaluation of the sustainability governance system design supports the system in remaining “good” in conditions that are complex and dynamic. Finally, we pull from the literature in a broad range of sciences to propose a conceptual “governance research framework” that aims to facilitate an integrated understanding of how the design of sustainability governance systems influences the legitimacy and trust granted to them by relevant actors. The framework is intended to enhance the adaptive features of sustainability governance systems so as to allow the identification of the causes of existing and emerging sustainability governance crises and finding solutions to them. Knowledge generated from its use may form a basis for providing policy recommendations on how to practically solve complex legitimacy and trust crises related to sustainability governance.

Migraine and sleep disorders are common in the general population, may be associated with each other and often significantly reduce patients’ quality of life. Clinicians and epidemiological studies have long acknowledged a link between these conditions. However, the exact nature of this relationship, its underlying mechanisms and patterns are complex and not fully understood. This publication brings together the latest data on the relationship between migraine and sleep disorders: the biochemical and functional-anatomical background, the mutual influence of these conditions on each other and the typical sleep disturbances in migraine patients (such as insomnia, obstructive sleep apnea, parasomnia, snoring, excessive daytime sleepiness). The paper discusses the hypotheses of pathogenetic relationships based on the studies of the central nervous system’s anatomical and physiological features in people with migraine and sleep disorders. The available data should encourage physicians to evaluate sleep quality in migraineurs and use combination therapy systematically. The therapy of insomnia is reviewed: both nonpharmacological and pharmacological therapies are discussed; the advantages of an integrated approach are discussed, and a brief overview of each group of medications is offered.Lastly, a case study of a patient with chronic migraine and insomnia treated with Doxylamine in combination therapy is presented. Treatment with Doxylamine significantly reduced the incidence of insomnia, probably thereby positively influencing the course of migraine as well.

The second year of the COVID-19 (coronavirus disease) pandemic has seen the need to identify and assess the long-term consequences of a SARS-CoV-2 infection on an individual’s overall wellbeing, including adequate cognitive functioning. ‘Cognitive COVID’ is an informal term coined to interchangeably refer to acute changes in cognition during COVID-19 and/or cognitive sequelae with various deficits following the infection. These may manifest as altered levels of consciousness, encephalopathy-like symptoms, delirium, and loss of various memory domains. Dysexecutive syndrome is a peculiar manifestation of ‘Cognitive COVID’ as well. In the previous major outbreaks of viruses like SARS-CoV, MERS-CoV and Influenza. There have been attempts to understand the underlying mechanisms describing the causality of similar symptoms following SARS-CoV-2 infection. This review, therefore, is attempting to highlight the current understanding of the various direct and indirect mechanisms, focusing on the role of neurotropism of SARS-CoV-2, the general pro-inflammatory state, and the pandemic-associated psychosocial stressors in the causality of ‘Cognitive COVID.’ Neurotropism is associated with various mechanisms including retrograde neuronal transmission via olfactory pathway, a general hematogenous spread, and the virus using immune cells as vectors. The high amounts of inflammation caused by COVID-19, compounded with potential intubation, are associated with a deleterious effect on the cognition as well. Finally, the pandemic’s unique psychosocial impact has raised alarm due to its possible effect on cognition. Furthermore, with surfacing reports of post-COVID-vaccination cognitive impairments after vaccines containing mRNA encoding for spike glycoprotein of SARS-CoV-2, we hypothesize their causality and ways to mitigate the risk. The potential impact on the quality of life of an individual and the fact that even a minor proportion of COVID-19 cases developing cognitive impairment could be a significant burden on already overwhelmed healthcare systems across the world make it vital to gather further evidence regarding the prevalence, presentation, correlations, and causality of these events and reevaluate our approach to accommodate early identification, management, and rehabilitation of patients exhibiting cognitive symptoms.

It is important to reduce poststroke depression (PSD) to improve the stroke outcomes and quality of life in stroke patients, but the underlying mechanisms of PSD are not completely understood. As many studies implicate dysregulation of hypothalamic-pituitary-adrenal axis in the etiology of major depression and stroke, we compared the cortisol awakening response (CAR) of 28 admitted PSD patients with that of 23 age-matched caregiver controls. Saliva samples for cortisol measurement were collected immediately, 15, 30, and 45 min after awakening for two consecutive days. Depressive mood status in PSD patients was determined with Beck Depression Inventory and Hamilton Depression Rating Scale. Salivary cortisol levels of PSD patients did not rise significantly at any sampling time, showing a somewhat flat curve. Caregiver controls showed significantly higher CAR at 15 and 30 min after awakening compared to PSD patients even though the two groups did not differ at awakening or 45 min after awakening. Area-under-the-curve analysis revealed a significant negative correlation between the CAR and the degree of depression in PSD patients. Thus, our findings suggest that poststroke depression is closely related with dysfunctional HPA axis indicated by blunted CAR.

Seventy-one students in two community college Statistics for the Social Sciences classes took six exams either individually or collaboratively. Assignment to test condition was randomly determined for each exam. Scores on collaboratively-taken exams were significantly higher than those for individually-taken exams, particularly for students with low GPAs and high test anxiety. Women’s, but not men’s, performances on the mid-term and final exams was related to the quality and quantity of their collaborative interactions. Thus, examining both quantity and quality of collaboration adds to our understanding of the underlying mechanisms of collaborative testing.

Abstract The number and quality of oocytes, as well as the decline in both of these parameters with age, determines reproductive potential in women. However, the underlying mechanisms of this diminution are incompletely understood. Previously, we identified novel roles for CHTF18 (Chromosome Transmission Fidelity Factor 18), a component of the conserved Replication Factor C-like complex, in male fertility and gametogenesis. Currently, we reveal crucial roles for CHTF18 in female meiosis and oocyte development. Chtf18−/− female mice are subfertile and have fewer offspring beginning at 6 months of age. Consistent with age-dependent subfertility, Chtf18−/− ovaries contain fewer follicles at all stages of folliculogenesis than wild type ovaries, but the decreases are more significant at 3 and 6 months of age. By 6 months of age, both primordial and growing ovarian follicle pools are markedly reduced to near depletion. Chromosomal synapsis in Chtf18−/− oocytes is complete, but meiotic recombination is impaired resulting in persistent DNA double-strand breaks, fewer crossovers, and early homolog disjunction during meiosis I. Consistent with poor oocyte quality, the majority of Chtf18−/− oocytes fail to progress to metaphase II following meiotic resumption and a significant percentage of those that do progress are aneuploid. Collectively, our findings indicate critical functions for CHTF18 in ensuring both the quantity and quality of the mammalian oocyte pool.

Abstract CBP (carboplatin) is a second-generation chemotherapeutic drug of platinum compound commonly applied in the treatment of sarcomas and germ cell tumours. Although it is developed to replace cisplatin, which has been proven to have a variety of side effects during cancer treatment, CBP still exhibits a certain degree of toxicity including neurotoxicity, nephrotoxicity, hematotoxicity and myelosuppression. However, the underlying mechanisms regarding how CBP influences the female reproductive system especially oocyte quality have not yet been fully determined. Here, we report that CBP exposure led to the oocyte meiotic defects by impairing the dynamics of the meiotic apparatus, leading to a remarkably aberrant spindle organisation, actin polymerisation and mitochondrial integrity. Additionally, CBP exposure caused compromised sperm binding and fertilisation potential of oocytes by due to an abnormal distribution of cortical granules and its component ovastacin. More importantly, we demonstrated that vitamin C supplementation prevented meiotic failure induced by CBP exposure and inhibited the increase in ROS levels, DNA damage accumulation and apoptotic incidence. Taken together, our findings demonstrate the toxic effects of CBP exposure on oocyte development and provide a potential effective way to improve the quality of CBP-exposed oocytes in vitro.

This research aims at analyzing the impact of consumers' perceptions of Corporate Social Responsibility (CSR) activities on their trust toward the company and at highlighting the underlying mechanisms and conditions of this impact. This paper is based on a questionnaire survey administered to a sample of 618 consumers about cosmetics and sportswear. Results show that consumers' perceptions of CSR activities have a positive influence on their trust toward the company, directly and indirectly through the influence on perceived quality of the products offered and consumer satisfaction.
