The loss of inner ear hair cells causes permanent hearing and balance deficits in humans and other mammals, but nonmammals recover after supporting cells (SCs) divide and replace hair cells. The proliferative capacity of mammalian SCs declines as exceptionally thick circumferential F-actin bands develop at their adherens junctions. We hypothesized that the reinforced junctions were limiting regenerative responses of mammalian SCs by impeding changes in cell shape and epithelial tension. Using mi...

Vaccines are essential to create a more resilient economic growth model. Ending the COVID-19 pandemic requires a more coordinated, effective, and equitable distribution of vaccines across the countries. Therefore, governments are in a race to increase the vaccination rates of the population. Given this backdrop, this paper focuses on the daily vaccinations per million data from March 1, 2021, to October 15, 2021, in 37 Organisation for Economic Co-operation and Development (OECD) countries and e...

Motivated by the Covid-19 pandemic, most students of higher education institutions in Portugal experienced online learning from March 2020 to July 2020. Based on the answers by students to a set of two open questions included in a questionnaire, this paper aims to identify the positive (strengths) and negative (weaknesses) aspects of online learning during this period, which is also known as emergency remote teaching. 2,107 valid answers were gathered. Issues related to comfort and time manageme...

Increasing rates of physical inactivity and sedentary behaviours among children and youth are important determinants of chronic disease. Supporting children’s participation in organized physical activities like sports has been promoted as a public health strategy to increase physical activity. Evidence shows that successful interventions are family-focused although research on how parental eating and physical activity behaviours influence children’s behaviours is deficient. In this commentar...

The Sars-Cov2 health emergency has demonstrated the need for developing structured telemedicine systems to protect citizens from the spread of the virus. Thereby, their importance and the nessecity to tailor their diffusion at large scale for providing services both at a distance and in time has been shown. For these reasons, the European Union advocates the digital transition of health systems for the next five years. The main aim of this work is to revisit the telemedicine research projects fi...

Women’s entrepreneurship is critical to an economy’s growth and development, yet it faces a variety of difficulties. This study aims to conduct a theoretical assessment of women’s entrepreneurship in Yemen and examine the problems it faces in its development. The findings show that women entrepreneurs in Yemen face numerous hurdles, including social, cultural, and institutional barriers; financial constraints; a lack of entrepreneurial education and knowledge; and a deficiency in training ...

Migration is a stressful experience and research shows that newly arrived migrants in Sweden suffer from different challenges and struggle to relate to parenting in a new culture that is different from their own. The Swedish Child Health Services (CHS) focuses on promoting health among children, as well as supporting parents in parenting. Although this is a goal, migrant parents participate at lower rates in parental support groups. This paper aims to discuss how the Swedish CHS can support thes...

The activity of marine microorganisms depends on community composition, yet, in some oceans, little is known about the environmental and ecological processes that structure their distribution. The objective of this study was to test the effect of geographic distance and environmental parameters on prokaryotic community structure in the Southern Ocean (SO). We described the total (16S rRNA gene) and the active fraction (16S rRNA-based) of surface microbial communities over a ~6.500 km longitudina...

About 70% of the world's population will live in urban areas by 2050, emphasizing the importance of assessment tools to guide decisions towards more sustainable cities. The ‘Mandala ODS’ is an alternative tool promoted by the Brazilian government to quantify the sustainability of cities based on the UN SDGs. Although diagnoses are important steps for governance, the behavioral profile of decision makers also appears as a key aspect. This work aims to assess the potential association evid...
