Plastics are a frequently observed component of marine debris and there is growing concern about microplastic (MP) ecotoxicity, and the impacts of additives, sorbed hazardous organic contaminants, heavy metals, and biofilm on MP surfaces. The relative importance of MP from different terrestrial and freshwater sources is poorly understood and limits our ability to develop best management practices. This review focuses on evidence and methods for source apportionment of MP in freshwater environments including the use of MP characteristics, mass balance techniques, and surface characteristics.

Background: The International Diabetes Federation (IDF) launched the Kids and Diabetes in School (KiDS) project in collaboration with the International Society for Paediatric and Adolescent Diabetes (ISPAD) and Sanofi Diabetes to inform and teach school staff, children and parents on the management of diabetes in school. Brazil and India were chosen as pilot countries. Methods: The evaluation was conducted using a qualitative methodology using semi-structured face to face in-depth interviews.

N-type Mg3Sb2-based Zintl compounds have attracted considerable interest in recent years for their high thermoelectric performance. Mg3Sb2-based compounds inherently have p-type transport properties because of the presence of intrinsic Mg vacancies. Therefore, eliminating Mg vacancies and increasing the electron concentration are crucial for achieving high-performance n-type Mg3Sb2-based materials. The addition of excess Mg in the initial composition and the doping of chalcogens (Te, Se, and S) at the Sb site have been the primary methods used to date.

The built environment is responsible for large negative ecological impacts due in part to the vast amount of materials used in construction. Concurrently, construction and demolition activities result in vast amounts of materials being buried, burnt, and dumped. It is essential therefore to analyze the impact of building materials acquisition, use, and transformation on the ecosystems people inhabit and rely upon for well-being. Typically, this is examined in terms of material use, energy use, and emission of pollutants including greenhouse gases.

The current paper addresses the nature of epistemic injustice as it may be experienced by persons with dementia. We describe how theoretical models of stigma align with the current model of epistemic injustice through a consideration of the concepts of ‘stereotype’ ‘prejudice’ and ‘discrimination’ shared by the two models. We draw on current understandings of dementia-related stigma to expand understandings of the epistemic injustice faced by persons with dementia.

Altered synaptic structure and function is a major hallmark of fragile X syndrome (FXS), autism spectrum disorders (ASDs), and other intellectual disabilities (IDs), which are therefore classified as synaptopathies. FXS and ASDs, while clinically and genetically distinct, share significant comorbidity, suggesting that there may be a common molecular and/or cellular basis, presumably at the synapse.

Alzheimer's disease (AD) is considered a polygenic disorder. This view is clouded, however, by lingering uncertainty over how to treat the quasi “monogenic” role of apolipoprotein E (APOE). The APOE4 allele is not only the strongest genetic risk factor for AD, it also affects risk for cardiovascular disease, stroke, and other neurodegenerative disorders. This review, based mostly on data from human studies, ranges across a variety of APOE-related pathologies, touching on evolutionary genetics and risk mitigation by ethnicity and sex.

There is a metabolic rift running through our economy and culture, and it is distracting our attention from care for the biosphere. To heal this rift, the diverse groups of people that make up humankind need a shared purpose that everyone can relate to and support. A strong candidate for that shared purpose is care for the bioregion—bioregioning—as an activity that creates value.

Research into alternative renewable energy generation is a priority, due to the ever-increasing concern of climate change. Microbial fuel cells (MFCs) are one potential avenue to be explored, as a partial solution towards combating the over-reliance on fossil fuel based electricity. Limitations have slowed the advancement of MFC development, including low power generation, expensive electrode materials and the inability to scale up MFCs to industrially relevant capacities. However, utilisation of new advanced electrode-materials (i.e.

Study objective: We estimate emergency department (ED) use differences across Medicare enrollees of different race/ethnicity who are residing in the same zip codes. Methods: In this retrospective cohort study, we stratified all Medicare fee-for-service beneficiaries aged 66 years and older (2006 to 2012) by residence zip code and identified zip codes with racial/ethnic diversity, defined as containing at least 1 enrollee from each of 3 racial/ethnic groups: Hispanics, (non-Hispanic) blacks, and (non-Hispanic) whites.
