The migration of retinal pigment epithelial (RPE) cells is an important step in various pathologic conditions including subretinal neovascularization (SRN), proliferative vitreoretinopathy (PVR) and, importantly, as a consequence of retinal surgery. Therefore, the elucidation of the mechanisms underlying RPE trans-differentiation and migration is essential for devising effective treatments aimed to the prevention of these disorders. A common event in these pathologies is the alteration of the blood-retina barrier (BRB), which allows the interaction of RPE cells with thrombin, a pro-inflammatory protease contained in serum...

A suspected increase in the salinity of fresh water resources can trigger a site investigation to identify the source(s) of salinity and the extent of any impacts. These investigations can be complicated by the presence of naturally elevated total dissolved solids or chlorides concentrations, multiple potential sources of salinity, and incomplete data and information on both naturally occurring conditions and the characteristics of potential sources. As a result, data evaluation techniques that are effective at one site may not be effective at another...

This review focuses only on specific studies into the SUS regionalization process, which were based on empirical results and published since 2006, when the SUS was already under the aegis of the Pact for Health framework. It was found that the regionalization process is now underway in all spheres of government, subject to a set of challenges common to the different realities of the country. These include, primarily, that committee-structured entities are valued as spaces for innovation, yet also strive to overcome the bureaucratic and clientelist political culture...

This paper analyzes the implementation process of the Public Action Organizational Contract (Coap) and its impacts on state agendas of SUS regionalization, comparing the different institutional reactions of the states to the strategy proposed by Decree 7.508/11. The comparison of developing dynamics of state agendas took as reference a normative baseline structured in eight strategic political-institutional moments in the implementation of the Coap in accordance with the logic defined in Decree 7.508/11. We collected data through a questionnaire containing 35 questions (1 open, 25 closed and 9 mixed) and extensive documentary research in 2013 and 2014 in all states, except for the Federal District...

This article analyzes governance in health regions, through the contributions of two studies: one on a governance model and the other on duties in the management of public policies networks. The former conducted a meta-analysis of 137 case studies in the literature on collaborative governance aimed at preparing an explanatory and analytical model. Authors identified critical variables that will influence the results: a previous history of conflict or cooperation, incentives for participation, power imbalances, leadership and institutional design...

Decentralization and regionalization are strategic themes for reforms in the health system. This paper analyzes the complex process of health regionalization being developed in Brazil. This paper identifies that the normative framework from the Brazilian National Health System, SUS has made advances with respect to its institutionalization and overcoming the initial centrality involved in municipalization. This has strengthened the development of regionalization and the intergovernmental agreement on health but the evidence points to the need to promote a revision...

Reshma Gupta, Christopher Moriates
As health system leaders strategize the best ways to encourage the transition toward value-based health care, the underlying culture-defined as a system of shared assumptions, values, beliefs, and norms existing within an environment-continues to shape clinician practice patterns. The current prevailing medical culture contributes to overtesting, overtreatment, and health care waste. Choosing Wisely lists, appropriateness criteria, and guidelines codify best practices, but academic medicine as a whole must recognize that faculty and trainees are all largely still operating within the same cultural climate...

We investigated how the ability to suppress an impending movement is affected by the visual salience of the stop-signal in a reaching countermanding task. We found that when the stop-signal was easy to detect, stop performance was better than when the stop-signal was difficult to detect. In an exploratory analysis, we also found that the change in salience of the stop-signal can have an effect on the speed of response in trials following the stop-signal. This effect occurred together with strategic slowing down after an error in inhibiting was committed and together with a repetition priming effect due to the stop-signal presented in the previous trial...

Tongyu Wang, David Torres, Félix E Fernández, Chuan Wang, Nelson Sepúlveda
The search for higher-performance photothermal microactuators has typically involved unavoidable trade-offs that hinder the demonstration of ubiquitous devices with high energy density, speed, flexibility, efficiency, sensitivity, and multifunctionality. Improving some of these parameters often implies deterioration of others. Photothermal actuators are driven by the conversion of absorbed optical energy into thermal energy, which, by different mechanisms, can produce mechanical displacement of a structure...

INTRODUCTION: The Veterans Health Administration (VHA), the largest integrated healthcare delivery system in the United States, is charged with ensuring timely access to high-quality care for veterans during disasters, and supporting national, state, local, and tribal emergency management and homeland security efforts. In 2008, the VHA Office of Public Health (OPH) sponsored the first VHA Emergency Management Research Agenda-setting conference to develop research priorities that address the needs of veterans and to position VHA as a national leader in emergency management by having VHA serve as a "laboratory" for the development of evidence-based emergency management practices...

Health care delivery in Oman has attained great heights since the modern renaissance in 1970. Although the health service had the main impetus all these years, the importance of health research began to take place by mid 1990's and is now gaining momentum as an important responsibility and activity of the Ministry of Health (MoH). Although there has been progressively increasing investment and commitment to research activities in the recent Five Year Plan for Health Development, it still lags behind in the quality and quantity of research output...

BACKGROUND: Biomass pretreatment remains an essential step in lignocellulosic biofuel production, largely to facilitate the efficient removal of lignin and increase enzyme accessibility to the polysaccharides. In recent years, there have been significant efforts in planta to reduce lignin content or modify its composition to overcome the inherent recalcitrance that it imposes on lignocellulosic biomass during processing. Here, transgenic poplar lines in which monolignol ferulate conjugates were synthesized during cell wall development to introduce, during lignification, readily cleavable ester linkages into the lignin polymer backbone (i...

Reducing the burden of neglected tropical diseases (NTDs) is one of the key strategic targets advanced by the Sustainable Development Goals. Despite the unprecedented effort deployed for NTD elimination in the past decade, their control, mainly through drug administration, remains particularly challenging: persistent poverty and repeated exposure to pathogens embedded in the environment limit the efficacy of strategies focused exclusively on human treatment or medical care. Here, we present a simple modelling framework to illustrate the relative role of ecological and socio-economic drivers of environmentally transmitted parasites and pathogens...

Mitochondrial adaptation to different physiological conditions highly relies on the regulation of mitochondrial ultrastructure, particularly at the level of cristae compartment. Cristae represent the membrane hub where most of the respiratory complexes embed to account for OXPHOS and energy production in the form of adenosine triphosphate (ATP). Changes in cristae number and shape define the respiratory capacity as well as cell viability. The identification of key regulators of cristae morphology and the understanding of their contribution to the mitochondrial ultrastructure and function have become an strategic goal to understand mitochondrial disorders and to exploit as therapeutic targets...

BACKGROUND: In 2015/2016, an ACTwatch outlet survey was implemented to assess the anti-malarial and malaria testing landscape in Myanmar across four domains (Eastern, Central, Coastal, Western regions). Indicators provide an important benchmark to guide Myanmar's new National Strategic Plan to eliminate malaria by 2030. METHODS: This was a cross-sectional survey, which employed stratified cluster-random sampling across four regions in Myanmar. A census of community health workers (CHWs) and private outlets with potential to distribute malaria testing and/or treatment was conducted...
