Given the increasing levels of air pollution, understanding the direct shielding response of the skin to air pollutants as a whole under exclusion of the influence from the inside of body is important. We applied topically the water soluble ambient air pollutants to the mouse skin and observed the histological response using 0.3 mM of H2SO3 as a positive control. Water soluble air pollutants samples, WSAP24h and WSA72h, were collected by pumping the outdoor air into ddH2O for 24 and 72 h respectively during two periods with different air quality index (AQI). Morphological examination showed apparent thickening of the epidermal layer in the H2SO3 skin section and in the sections applied with WSAP24h and WSAP72h without significant difference in the extent of epidermal hyperplasia among three groups. The cell viability assay showed no cytotoxic effect by the treatment of H2SO3 and WSAP24h in human skin fibroblast WS-1 cells. WSAP72h sample revealed a dose-dependent cytotoxicity to skin fibroblasts at 48 hr. selleck The evidences indicated that the barrier function of the skin by epidermis hyperplasia could be activated by the insult of a component of air pollution, and the protection could be hold against a more complex and concentrated ambient air pollutants.Introduction The need for new antibacterial agents continues to grow, but success in development of antibiotics in recent years has been limited. To improve the chances that new compounds will progress into clinical trials and beyond, it is vital that we consider as early as possible in the process the various challenges that discoverers and developers of new antibiotics will face. Areas covered The author looks at the factors that affect medicinal chemistry aimed at providing successful antibacterial agents. Target selection, target inhibition, accumulation in bacteria, and pharmacokinetics are all discussed, with a particular emphasis on how our current understanding should impact design and optimization strategies. Expert opinion From the perspective of a medicinal chemist, the primary question when considering the various aspects of antibacterial drug discovery should be 'what can I design for?' It is important to be aware of the limitations of our understanding, and also the constraints and challenges that arise due to the diversity of the bacteria we try to address. Progress is needed to simplify approval pathways and to increase return on investment for the next generations of clinically useful agents to succeed.Adult children's particular obligations to their parents are filial obligations. The gratitude of filial obligations that treats one's filial obligations as duties of gratitude to one's parents is a mainstream view. However, in terms of the requirements of such obligations, the gratitude account fails to provide practical guidance. The general requirement seems that children should benefit their parents as the beneficiary should benefit the benefactor. The question is what kinds of benefits adult children should provide to their parents? In some cases, adult children feel obligated to provide particular benefits to their parents like paying their medical bills or spending time with them. While in some other cases, it seems that they can use their own discretion to decide how to satisfy the filial obligations so long as what they do benefits their parents. In this article, I am trying to argue that although the general requirement of the filial obligations is to benefit the parents, there are two kinds of benefits that adult children are strongly obligated to provide. These are special goods that parents can only get from their children and things that meet their parents' basic needs. In addition, although adult children have filial obligations to benefit their parents, there should be some limitations on the requirements of filial obligation. Namely, adult children do not have a filial obligation to meet their parents' desires that could only be satisfied at the cost of adult children's liberty related to significant aspects of their lives, or to meet their parents' desires that could only be satisfied at the cost of infringing their capacity to fulfil other important duties.Underpinned by the notion that community voices should be central to the development of localized communication infrastructures for health and well-being, this study applied Dutta's culture-centered approach to examine the meanings of health and the navigation of being healthy among 118 people residing in low-income suburban areas in Aotearoa New Zealand. The culture-centered approach is based on dialog between researchers and community members, and it centralizes local contexts by building theories from within the culture and co-creating dialogic spaces of listening, formed at the intersection of structure, culture, and agency. In this study, participants constructed health in relation to food, housing, and health care, underpinned by financial inaccessibility and a deep-rooted cultural conflict between the collectivist norms practiced by the community and the neoliberal individualized structure. The study illuminates how the pathologization of culture by structure constitutes poor health outcomes and how agentic expressions of culture negotiate local structures to regain health and well-being through acts of resistance.In a complex medical center environment, the occupants of newly built or renovated spaces expect everything to "function almost perfectly" immediately upon occupancy and for years to come. However, the reality is usually quite different. The need to remediate initial design deficiencies or problems not noted with simulated workflows may occur. In our intensive care unit (ICU), we were very committed to both short-term and long-term enhancements to improve the built and technological environments in order to correct design flaws and modernize the space to extend its operational life way beyond a decade. In this case study, we present all the improvements and their background in our 20-bed, adult medical-surgical ICU. This ICU was the recipient of the Society of Critical Care Medicine's 2009 ICU Design Award Citation. Our discussion addresses redesign and repurposing of ICU and support spaces to accommodate expanding clinical or entirely new programs, new regulations and mandates; upgrading of new technologies and informatics platforms; introducing new design initiatives; and addressing wear and tear and gaps in security and disaster management.
