Wilfred Beaudoin, Adam Moore
In the past several years, there has been an important movement to reduce the utilization of restraint for individuals with developmental disabilities. Legislatures, local and national, are taking on the task of shaping the way that our culture supports people who, up until now, have been often treated in a punitive manner rather than truly supportive in a therapeutic way. Schools and systems of care struggle to identify strategies that offer more positive outcomes to all individuals, even those with challenging behaviors...

Laurens van Gelderen, Grunde Jomaas
A new method for the simultaneous study of the flammability and burning efficiency of fresh and weathered crude oil through two experimental laboratory setups is presented. The experiments are easily repeatable compared to operational scale experiments (pool diameter ≥2 m), while still featuring quite realistic in situ burning conditions of crude oil on water. Experimental conditions include a flowing water sub-layer that cools the oil slick and an external heat flux (up to 50 kW/m2 ) that simulates the higher heat feedback to the fuel surface in operational scale crude oil pool fires...

A genetic linkage between a conserved gene cluster (Nit1C) and the ability of bacteria to utilize cyanide as the sole nitrogen source was demonstrated for nine different bacterial species. These included three strains whose cyanide nutritional ability has formerly been documented (Pseudomonas fluorescens Pf11764, Pseudomonas putida BCN3 and Klebsiella pneumoniae BCN33), and six not previously known to have this ability [Burkholderia (Paraburkholderia) xenovorans LB400, Paraburkholderia phymatum STM815, Paraburkholderia phytofirmans PsJN, Cupriavidus (Ralstonia) eutropha H16, Gluconoacetobacter diazotrophicus PA1 5 and Methylobacterium extorquens AM1]...

Living drug delivery system has been proposed as new concept materials since it is able to communicate with biological system, sense subtle changes of body microenvironment caused by disease and then make rapid response to cure in early stage of disease. Herein, taking full advantage of the tumor hypoxia physiology and successive effects of photodynamic therapy (PDT), we designed a new living delivery system via combining the PDT and hypoxia-responsive chemotherapy, abbreviated as Ce6-PEG-Azo-PCL. Then, according to the facts that oxygen can be converted into reactive oxygen species during irradiation of the photosensitizer, tumor cells could be killed after the poly(ethylene glycol) (PEG) conjugated photosensitizer chlorine e6 were irradiated at tumor site...

Cochlear implants (CIs) often work very well for many children and adults with profound sensorineural (SNHL) hearing loss. Unfortunately, while many CI patients display substantial benefits in recognizing speech and understanding spoken language following cochlear implantation, a large number of patients achieve poor outcomes. Understanding and explaining the reasons for poor outcomes following implantation is a very challenging research problem that has received little attention despite the pressing clinical significance...

The microscopic examination of fifty-five serially sectioned implanted temporal bones has provided insight into what is being stimulated; and the changes that are the result of the insertion and presence of the implant. The ganglion cell bodies (neurons) are structures being stimulated (two laboratories have reported an inverse relationship of the number of neurons and performance). Insertion through the round window, verses a cochleostomy, produces the least fibrosis and new bone. Fibrosis and new bone do not affect the implant function unless they form in the scala vestibuli in the region of the ductus reuniens, and, block it; and produce cochlear hydrops resulting in a delayed low tone loss of hearing in hybrid implants...

William E Klunk
Over the past 40 years, brain molecular imaging has evolved from measuring cerebral metabolism with fluorodeoxyglucose, to neuroreceptor imaging, to imaging pathological protein deposits. In the early going, the characteristics of successful molecular imaging radiotracers were defined, and a detailed "Process" was developed for the collection of basic pharmacodynamic and pharmacokinetic data. These data are essential for the interpretation of in vivo imaging data and for defining the strengths, weaknesses, and limitations of new tracers...

REVIEW
Joseph L Howard, Qun Cao, Duncan L Browne
Mechanochemistry is becoming more widespread as a technique for molecular synthesis with new mechanochemical reactions being discovered at increasing frequency. Whilst mechanochemical methods are solvent free and can therefore lead to improved sustainability metrics, it is more likely that the significant differences between reaction outcomes, reaction selectivities and reduced reaction times will make it a technique of interest to synthetic chemists. Herein, we provide an overview of mechanochemistry reaction examples, with 'direct' comparators to solvent based reactions, which collectively seemingly show that solid state grinding can lead to reduced reaction times, different reaction outcomes in product selectivity and in some instances different reaction products, including products not accessible in solution...

Existing models for assigning species, subspecies, or no taxonomic rank to populations which are geographically separated from one another were analyzed. This was done by subjecting over 3,000 pairwise comparisons of vocal or biometric data based on birds to a variety of statistical tests that have been proposed as measures of differentiation. One current model which aims to test diagnosability (Isler et al. 1998) is highly conservative, applying a hard cut-off, which excludes from consideration differentiation below diagnosis...

David Kaldewey
This article analyzes the concept of "grand challenges" as part of a shift in how scientists and policymakers frame and communicate their respective agendas. The history of the grand challenges discourse helps to understand how identity work in science and science policy has been transformed in recent decades. Furthermore, the question is raised whether this discourse is only an indicator, or also a factor in this transformation. Building on conceptual history and historical semantics, the two parts of the article reconstruct two discursive shifts...

Eloise A Stark, Peter Vuust, Morten L Kringelbach
For Aristotle, the goal of human life was to live well, to flourish, and to ultimately have a good life. These goals can be conceptualized as "eudaimonia," a concept distinct from "hedonia" (pleasure). Many people would argue that the arts play a large role in their well-being and eudaimonia. Music in particular is a culturally ubiquitous phenomenon which brings joy and social bonding to listeners. Research has given insights into how the "sweet anticipation" of music and other art forms can lead to pleasure, but a full understanding of eudaimonia from the arts is still missing...

This review presents the main contributions to our knowledge regarding the development of antivenoms for therapeutic use in victims of venomous animal bites. We cover the progress of serum therapy since tetanus and diphtheria antitoxins in Germany and France until the current scenario of antivenom production worldwide. During these more than 120 years of antivenom development, many researchers contributed to establish what are nowadays the antivenoms used for therapeutic purpose. The history of antivenoms development is fascinating! This review aims to recognize all those who contributed to the establishment of new sera, new methodologies and saving lives: much more than Calmette and Vital Brazil...

BACKGROUND: Human mutagenesis has a large stochastic component. Thus, large coding regions, especially cytoskeletal and extra-cellular matrix protein (CECMP) coding regions are particularly vulnerable to mutations. Recent results have verified a high level of somatic mutations in the CECMP coding regions in the cancer genome atlas (TCGA), and a relatively common occurrence of germline, deleterious mutations in the TCGA breast cancer dataset. METHODS: The objective of this study was to determine the correlations of CECMP coding region, germline nucleotide variations with both overall survival (OS) and disease-free survival (DFS)...

INTRODUCTION: Medical faculties have the responsibility to graduate competent health professionals and a consequent obligation to assure the quality and effectiveness of their students' clinical teaching. Many institutions are responding to rural workforce needs by extending clinical training from the traditional academic teaching hospital to include rural and remote sites distributed away from the central training institution. It is incumbent upon medical schools to consider how this might impact on the faculty development of these clinicians as teachers...

PURPOSE: To understand the preconception experiences of women with epilepsy who have been taking the teratogenic drug valproate. METHODS: Seven women were recruited, three from a preconception clinic and four from an antenatal clinic in a region of the UK. All had taken valproate preconceptionally. Three preconception clinic encounters were observed and audio-recorded. Interviews with all women were analysed using Interpretative Phenomenological Analysis (IPA). RESULTS: Women experienced a "trajectory of balance"...

HYPOTHESIS: The adsorption kinetics of heptadecafluoro-1-nonanol (C9 H2 F17 OH) onto a clean air-water interface at low surfactant concentrations (equilibrium surface tension, γ(C) > 65 mN/m) has been reported, and the controlling mechanism was found to be mixed diffusive-kinetic controlled (Kuo et al., JCIS 402 (2013) 131). However, it remains to be determined what the adsorption kinetics are at higher concentrations. Hence, the dynamic surface tension, γ(t) of C9 H2 F17 OH was measured and compared with the theoretical γ(t) curves predicted from phase transition model...
