This manuscript describes a high-temperature flow reactor experiment coupled to the powerful molecular beam mass spectrometry (MBMS) technique. This flexible tool offers a detailed observation of chemical gas-phase kinetics in reacting flows under well-controlled conditions. The vast range of operating conditions available in a laminar flow reactor enables access to extraordinary combustion applications that are typically not achievable by flame experiments. These include rich conditions at high temperatures relevant for gasification processes, the peroxy chemistry governing the low temperature oxidation regime or investigations of complex technical fuels...

BACKGROUND: Interest in the Senian capability framework as an alternative approach to wellbeing measurement has increased in recent decades. The aim of this study was to look at the extent to which an individual's capability to achieve wellbeing in one dimension is associated with his or her attempt to achieve wellbeing in another dimension in a fragile setting affected by conflict. METHODS: Capability is defined as the ability to achieve health, knowledge, and wealth and is measured as latent variables using a structural equation model...

Cell differentiation is controlled by individual transcription factors (TFs) that together activate a selection of enhancers in specific cell types. How these combinations of TFs identify and activate their target sequences remains poorly understood. Here, we identify the cis -regulatory transcriptional code that controls the differentiation of serotonergic HSN neurons in C. elegans . Activation of the HSN transcriptome is directly orchestrated by a collective of six TFs. Binding site clusters for this TF collective form a regulatory signature that is sufficient for de novo identification of HSN neuron functional enhancers...

BACKGROUND: The Global Fund encourages operational research (OR) in all its grants; however very few reports describe this aspect. In India, Project Axshya was supported by a Global Fund grant to improve the reach and visibility of the government Tuberculosis (TB) services among marginalised and vulnerable communities. OR was incorporated to build research capacity of professionals working with the national TB programme and to generate evidence to inform policies and practices. OBJECTIVES: To describe how Project Axshya facilitated building OR capacity within the country, helped in addressing several TB control priority research questions, documented project activities and their outcomes, and influenced policy and practice...

Mounting evidence indicates that worldwide, innovation systems are increasing unsustainable. Equally, concerns about inequities in the science and innovation process, and in access to its benefits, continue. Against a backdrop of growing health, economic and scientific challenges global stakeholders are urgently seeking to spur innovation and maximize the just distribution of benefits for all. Open Science collaboration (OS) - comprising a variety of approaches to increase open, public, and rapid mobilization of scientific knowledge - is seen to be one of the most promising ways forward...

China has undertaken waves of healthcare reforms to keep pace with its rapid economic growth. By 2011, universal health insurance coverage was successfully achieved through the creation of a basic social medical insurance system. Growing economic power, extensive government subsidies, and strategies for program implementation are critical to that achievement. However, the breadth and depth of coverage varies considerably across insurance schemes and localities. The disjointed insurance scheme led to inequality in coverage, accessibility, and affordability of medical services, lopsided allocation of health resources, and increasing medical expenditures, and these remain crucial challenges for healthcare insurance coverage...

The principles of the Health in All Policies (HiAP) approach are not new. Their international roots can be traced back to 1978 and the Alma-Ata Declaration and the 1986 Ottawa Charter. In Finland, the roots of HiAP go back to 1972 when the Economic Council of Finland, chaired by the Prime Minister, launched the 'Report of the working group exploring the goals of health'. The paper discusses the history, rationale, and implementation of the principles underlying the umbrella concept of HiAP. A rationale for implementing a new concept - HiAP in 2006 during the Finnish European Union presidency - is given...

AIMS: The gradient in health inequalities reflects a relationship between health and social circumstance, demonstrating that health worsens as you move down the socio-economic scale. For more than a decade, the Norwegian National government has developed policies to reduce social inequalities in health by levelling the social gradient. The adoption of the Public Health Act in 2012 was a further movement towards a comprehensive policy. The main aim of the act is to reduce social health inequalities by adopting a Health in All Policies approach...

AIMS: Government programs and the Norwegian Directorate of Health give public health nurses in Norway an explicit role in population-based health promotion and disease-prevention work. The aim of this paper is to explore Norwegian public health nurses' experiences with population-based work. METHODS: A phenomenological hermeneutic approach was adopted, involving face-to-face interviews with a purposeful sample of 23 public health nurses from urban and rural districts in two counties in Norway...

Poria cocos is one of medical materials frequently used in China and well marketed at home and abroad. Based on the analysis of exports and imports data of P. cocos, we found that large proportions of P. cocos were exported, while only a small proportions of those were imported in China between 2011 and 2016. During periods of these six years, the annual exporting trade of P. cocos in quantity significantly decreased, but that in dollars tend to increase slightly and the unit-prices of P. cocos significantly increased...

Global health is increasingly reliant on financial markets. The ongoing financialisation of global health raises new questions of governance, which we expect to affect policy makers as much as doctors, nurses and patients in the years to come. In this editorial, we will first explain what is meant by financialisation, then illustrate its nature in the field of global health via three examples, and end by highlighting some of the governance issues that the financialisation of global health raises.

The ability of non-governmental organizations, government agencies, and corporations to deliver and support the availability and use of interventions for improved global public health depends on their readiness to do so. Yet readiness has proven to be a rather fluid concept in global public health, perhaps due to its multidimensional nature and because scholars and practitioners have applied the concept at different levels such as the individual, organization, and community. This review concerns 30 publically available tools created for the purpose of organizational readiness assessment in order to carry out global public health objectives...

It is generally accepted that climate change will stress coldwater species like Pacific salmon. However, it is unclear what aspect of altered thermal regimes (e.g., warmer winters, springs, summers, or increased variability) will have the greatest effect, and what role the spatial properties of river networks play. Thermally diverse habitats may afford protection from climate change by providing opportunities for aquatic organisms to find and use habitats with optimal conditions for growth. We hypothesized that climate-altered thermal regimes will change growth and timing of life history events such as emergence or migration but that changes will be moderated in topologically complex stream networks where opportunities to thermoregulate are more readily available to mobile animals...

On December 11, 2013, the Indian Supreme Court recriminalized non-peno-vaginal sex under Sec. 377 of the Indian Penal Code (IPC), overturning a 2009 ruling that deemed IPC Sec. 377 unconstitutional. Similar "sodomy laws" in other countries have been associated with increased violence, harassment, and other discrimination against men who have sex with men (MSM) and transgender women. However, few studies have looked at the effects of such a law in an Indian context. This study examined experiences of victimization among MSM and hijra/transgender women (MSM-H) in the State of Maharashtra using a mixed-method approach...

T-cell development is coupled with a highly ordered migratory pattern. Lymphoid progenitors must follow a precise journey; starting from the hematopoietic tissue, they move toward the thymus and then migrate into and out of distinct thymic microenvironments, where they receive signals and cues required for their differentiation into naïve T-cells. Knowing where, when, and how these cells make directional "decisions" is key to understanding T-cell development. Such insights can be gained by directly observing developing T-cells within their environment under various conditions and following specific experimental manipulations...

Background and Objectives: After the U. S. Food and Drug Administration's recommendation against the use of power morcellation for tissue extraction in minimally invasive hysterectomy, the number of procedures completed laparoscopically declined in favor of open surgery laparotomy. We conducted a retrospective cohort study comparing perioperative and long-term outcomes, including complications associated with laparoscopic hysterectomy before and after the FDA recommendation. Methods: We included procedures performed in Danish government hospitals (GHs) and a hospital specializing in minimally invasive gynecological surgery (MIGS)...

Recurrent mutations in chromatin modifiers are specifically prevalent in adolescent or adult patients with Sonic hedgehog-associated medulloblastoma (SHH MB). Here, we report that mutations in the acetyltransferase CREBBP have opposing effects during the development of the cerebellum, the primary site of origin of SHH MB. Our data reveal that loss of Crebbp in cerebellar granule neuron progenitors (GNPs) during embryonic development of mice compromises GNP development, in part by downregulation of brain-derived neurotrophic factor (Bdnf)...
