The grand scale, ultimate efficiency, and sustainability of natural photosynthesis have inspired generations of researchers in biomimetic light energy utilization. As an essential and ubiquitous component in all photosynthetic machinery, lipids and their assemblies have long been recognized as powerful molecular scaffolds in building artificial photosynthetic systems. Model lipid bilayers, such as black lipid membranes and liposomes (vesicles), have been extensively used to host natural as well as synthetic photo- and redox-active species, thereby enabling key photosynthetic processes, such as energy transfer and photoinduced electron transfer, to be examined in well-defined, natural-like membrane settings...

BACKGROUND: Performance-based incentives (PBIs) have garnered global attention as a promising strategy to improve healthcare delivery to vulnerable populations. However, literature gaps in the context in which an intervention is implemented and how the PBIs were developed exist. Therefore, we (1) characterized the barriers and promoters to prevention of vertical transmission of HIV (PVT) service delivery in rural Mozambique, where the vertical transmission rate is 12 %, and (2) assessed the appropriateness for a PBI's intervention and application to PVT...

Despite the importance of individual contributors to financing federal candidates, past work has largely neglected this crucial financial constituency in favor of research on corporate and trade political action committees (PACs). By contrast, in this study I offer the first analysis of aggregate contributions from the population of individual contributors to House candidates. Using an original big dataset constructed from over fifteen million Federal Election Commission (FEC) disclosure records, I identify individual contributors (rather than contributions) and trace the variation in their strategies across types of House candidates...

This article responds to a debate article published in Human Reproduction earlier this year. In that article, the authors suggested that parents should be encouraged to disclose the use of donor gametes to their children given rapid and widespread advances in genetic testing and sequencing. However, there is an urgent need to engage with the assertion that in this context, telling children about their donor conception both safeguards and promotes their interests, particularly if such disclosure is motivated by parents' anxieties about accidental discovery...

Donor heart allocation in the United States has not evolved in concert with changes in the characteristics of patients on the waiting list or evolution in technology. Data showing the growing population of patients with advanced heart failure coupled with the relatively fixed number of cardiac donors and regional access disparities motivated the United Network for Organ Sharing (UNOS) Thoracic Committee to reexamine candidate prioritization and broader organ sharing. The resultant proposed policy change stratifies patients in a more granular manner based primarily on wait-list mortality and is designed to expand the geographic boundaries to permit greater access to donor hearts for the most critically ill patients awaiting transplant...

Global health and neoliberalism are becoming increasingly intertwined as organizations utilize markets and profit motives to solve the traditional problems of poverty and population health. I use field work conducted over 14 months in a global health technology company to explore how the promise of neoliberalism re-envisions humanitarian efforts. In this company's vaccine refrigerator project, staff members expect their investors and their market to allow them to achieve scale and develop accountability to their users in developing countries...

BACKGROUND: Patients travel worldwide for paid kidney transplants. Although transplantations abroad are not always illegal, they are commonly perceived to be illegal and unethical involving risks. AIM: We aimed to describe the motivations and experiences of patients who traveled abroad for paid kidney transplantations and to examine how these transplantations were facilitated. METHODS: We interviewed 22 patients who traveled from Macedonia/Kosovo, the Netherlands, and Sweden for paid kidney transplantations between years 2000 and 2009...

BACKGROUND: Public health has multicultural origins. By the close of the nineteenth century, Schools of Public Health (SPHs) began to emerge in western countries in response to major contemporary public health challenges. The Flexner Report (1910) emphasized the centrality of preventive medicine, sanitation, and public health measures in health professional education. The Alma Ata Declaration on Primary Health Care (PHC) in 1978 was a critical milestone, especially for low and middle-income countries (LMICs), conceptualizing a close working relationship between PHC and public health measures...

BACKGROUND: Although the demand for blood supply has progressively increased in developing countries, evidences indicate that there is a major shortage of blood and blood products in these countries, particularly in Ethiopia. Thus, identifying motivational factors affecting blood donation and recruitment of safe and low risk donors is necessary. For this reason, the study aimed at assessing knowledge, attitude, and practice towards blood donation and its associated factors. METHODS: A community based cross-sectional study was conducted in Debre Markos town from February to April, 2015...

During the 1990s, Brazil and Russia diverged in their policy response to AIDS. This is puzzling considering that both nations were globally integrated emerging economies transitioning to democracy. This article examines to what extent international pressures and partnerships with multilateral donors motivated these governments to increase and sustain federal spending and policy reforms. Contrary to this literature, the cases of Brazil and Russia suggest that these external factors were not important in achieving these outcomes...

Harnessing visible light as the driving force for chemical transformations generally offers a more environmentally friendly alternative compared with classical synthetic methodology. The transition metal-based photocatalysts commonly employed in photoredox catalysis absorb efficiently in the visible spectrum, unlike most organic substrates, allowing for orthogonal excitation. The subsequent excited states are both more reducing and more oxidizing than the ground state catalyst and are competitive with some of the more powerful single-electron oxidants or reductants available to organic chemists yet are simply accessed via irradiation...

Background. Though World Health Organization recommends 100% voluntary blood donation, the percentage of blood collected from voluntary blood donors and the average annual blood collection rate are extremely low in Ethiopia. The role of adults is crucial to meet the demand of safe blood. Thus, this study aimed to assess knowledge, attitude, and practice of adult population towards blood donation in Gondar town, Northwest Ethiopia. Method. A community based cross-sectional study was conducted among 768 adults...

Over the years, connection websites and speed dating events have increasingly attracted singles and couples who cannot have a child in the 'traditional' way. These initiatives bring together candidate gamete providers and recipients with the promise of offering more freedom of choice than fertility centres or sperm banks currently do. Depending on the level of contact desired, the role of the gamete provider may range from not being involved at all to sharing full parental rights and obligations. In this paper, we take a look at the ethical and social issues that emerge with these new forms of family arrangements...

Identification of the key components in the physical and chemical milieu directing donor cells into a desired phenotype is a requirement in the investigation of bioscaffolds for the advancement of cell-based therapies for retinal neurodegeneration. We explore the effect of electrospun poly-ε-caprolactone (PCL) fiber scaffold topography and functionalization and culture medium, on the behavior of mouse retinal cells. Dissociated mouse retinal post-natal cells were seeded on random or aligned oriented fibers, with or without laminin coating and cultured with either basic or neurotrophins enriched medium for 7days...

BACKGROUND: Improvement of the consent rate for solid organ donation from deceased donors is a key component of strategies applied in many countries aiming to increase the availability of organs for transplantation. Attitudes toward living and posthumous donation are favorable. Research shows that the outlook on organ donation and the degree of the willingness to become an organ donor are associated with a wide range of variables. The main objective of this study was to identify factors that influence the willingness to donate organs and the reasons for refusing consent...

PURPOSE OF REVIEW: Ischemia and reperfusion injury (IRI) in vascularized tissue allotransplantation (VCA) remain largely undefined. Because VCA is comprised of different tissues, the sensitivity towards IRI may not be uniform. We, herein, attempt to address mechanistic aspects of IRI in VCA and provide a summary on potential technologies and targets for amelioration or treatment of IRI in this novel field. RECENT FINDINGS: IRI results in a loosened architecture of musculature, hypertrophic, centrally located cell nuclei as well as a high degree of neovascularization...

Group A Streptococcus (GAS) infections cause substantial worldwide morbidity and mortality, mostly associated with suppurative complications such as pharyngitis, impetigo, and non-suppurative immune syndromes such as acute rheumatic fever, rheumatic heart disease, and acute post-streptococcal glomerulonephritis. Deaths occur mostly in children, adolescents, and young adults in particular pregnant women in low- and middle-income countries. GAS strains are highly variable, and a GAS vaccine would need to overcome the issue of multiple strains...
