Background and Objectives: U.S. Nursing homes (NH) are shifting toward a person-centered philosophy of care, where staff understand each residents preferences, goals and values, and seek to honor them throughout the care delivery process. Social interactions are a major component of life and while low rates of social interactions are typically found among NH residents, little research has examined resident preferences for specific types of social interactions. The purpose of this study is to explore, from the perspective of the NH resident, barriers to social contact preferences and situations when social preferences change...

It is common to use multiple field sampling methods when implementing wildlife surveys to compare method efficacy or cost-efficiency, integrate distinct pieces of information provided by separate methods, or evaluate method-specific biases and misclassification error. Existing models that combine information from multiple field methods or sampling devices permit rigorous comparison of method-specific detection parameters, enable estimation of additional parameters such as false-positive detection probability, and improve occurrence or abundance estimates, but with the assumption that the separate sampling methods produce detections independently of one another...

The transformation of lignocellulosic biomass into bio-based commodity chemicals is technically possible. Among thermochemical processes, fast pyrolysis, a relatively mature technology that has now reached the commercial level, produces a high yield of an organic-rich liquid stream. Despite the recent efforts in elucidating the degradation paths of biomass pyrolysis, the selectivity and recovery rates of bio-compounds remain low. In an attempt to clarify the general degradation scheme of biomass fast pyrolysis and provide a quantitative insight, this study has combined the use of fast pyrolysis micro-reactors, spectrometric techniques and mixtures of unlabelled and Carbon-13 enriched materials...

Amyotrophic lateral sclerosis (ALS) patients whose voluntary muscles are paralyzed commonly communicate with the outside world using eye movement. There have been many efforts to support this method of communication by tracking or detecting eye movement. An electrooculogram (EOG), an electro-physiological signal, is generated by eye movements and can be measured with electrodes placed around the eye. In this study, we proposed a new practical electrode position on the forehead to measure EOG signals, and we developed a wearable forehead EOG measurement system for use in Human Computer/Machine interfaces (HCIs/HMIs)...

The current era of healthcare reform emphasizes the provision of effective, safe, equitable, high-quality, and cost-effective care. Within the realm of gastrointestinal endoscopy in adults, renewed efforts are in place to accurately define and measure quality indicators across the spectrum of endoscopic care. In pediatrics, however, this movement has been less-defined and lacks much of the evidence-base that supports these initiatives in adult care. A need, therefore, exists to help define quality metrics tailored to pediatric practice and provide a toolbox for the development of robust quality improvement (QI) programs within pediatric endoscopy units...

To achieve Millennium Development Goal 5 on maternal health, many countries have focused on marginalized women who lack access to care. Promoting facility-based deliveries to ensure skilled birth attendance and emergency obstetric care has become a main measure for preventing maternal deaths, so women who opt for home births are often considered 'marginal' and in need of targeted intervention. Drawing upon ethnographic data from Nicaragua, this paper critically examines the concept of marginality in the context of official efforts to increase institutional delivery amongst the rural poor, and discusses lack of access to health services among women living in peripheral areas as a process of marginalization...

The maximum photosynthetic carboxylation rate (Vcmax ) is an influential plant trait that has multiple scaling hypotheses, which is a source of uncertainty in predictive understanding of global gross primary production (GPP). Four trait-scaling hypotheses (plant functional type, nutrient limitation, environmental filtering, and plant plasticity) with nine specific implementations were used to predict global Vcmax distributions and their impact on global GPP in the Sheffield Dynamic Global Vegetation Model (SDGVM)...

Although the concepts of systems change and sustainability are not new, little is known about the factors associated with systems change sustaining multi-state, multi-level fall prevention efforts. This exploratory study focuses on three State Departments of Health (DOH) that were awarded 5-year funding from the Centers for Disease Control and Prevention to simultaneously implement four separate yet related evidence-based fall prevention initiatives at the clinical, community, and policy level. The purpose of this study was to examine changes in partnerships and collaborative activities that occurred to accomplish project goals (examining changes in the context of "before funding" and "after funding was received")...

Rice (Oryza sativa L.) is often exposed to cool temperatures during spring planting in temperate climates. A better understanding of genetic pathways regulating chilling tolerance will enable breeders to develop varieties with improved tolerance during germination and young seedling stages. To dissect chilling tolerance, five assays were developed; one assay for the germination stage, one assay for the germination and seedling stage, and three for the seedling stage. Based on these assays, five chilling tolerance indices were calculated and assessed using 202 O...

We asked whether coordinated voluntary movement of the lower limbs could be regained in an individual having been completely paralyzed (>4 year) and completely absent of vision (>15 year) using two novel strategies-transcutaneous electrical spinal cord stimulation at selected sites over the spine as well as pharmacological neuromodulation by buspirone. We also asked whether these neuromodulatory strategies could facilitate stepping assisted by an exoskeleton (EKSO, EKSO Bionics, CA) that is designed so that the subject can voluntarily complement the work being performed by the exoskeleton...

Despite the highly economic value of tea in Africa, its genetic and geographic origins remain largely unexplored. Here we address this by collecting 439 samples across 11 countries in Africa and Asia to investigate the origin and genepool composition of African tea based on 23 nuclear microsatellites loci (nSSRs) and three cpDNA intergenic spacer regions. Our results indicated that the African tea represents a potpourri originating from multiple introductions over time. The nSSR analysis revealed that the majority (79%) of tea accessions collected in Africa belong to Indian Assam tea which have likely originated from India and/or Sri Lanka...

The impact of planetary mill pretreatment on corn stover size, crystallinity, and enzyme digestibility was investigated based on the grinding ball properties in an effort to reduce energy consumption. Alumina, zirconia, and steel balls were used, of which steel balls had the highest specific gravity but the lowest surface roughness while alumina balls had the lowest specific gravity and the highest roughness. The planetary mill pretreatment effectively reduced the size and crystallinity of the corn stover for all the ball types...

EAE is induced to susceptible mice using linear peptides of myelin proteins of the central nervous system. Specific peptide motifs within the peptide-binding groove of the MHC peptide-complex determines the affinity of the peptide in each animal and the consequent T-cell receptor recognition and activation of the cell. Altered peptide ligand (APL) vaccination is a novel approach based on an effort to induce T-cell tolerance or alter cytokine profile from pro-inflammatory to anti-inflammatory. In the present study we synthesized the MOG35-55 peptide and altered its 3-dimensional conformation to make it a cyclic one (c-MOG35-55)...

BACKGROUND: The growing menace of poor quality and falsified drugs constitutes a major hazard, compromising healthcare and patient outcomes. Efforts to assess drug standards worldwide have almost exclusively focused on anti-microbial drugs; with no study to date on cardiovascular drugs. Our study aims to assess quality of seven routinely used cardiovascular medications (anticoagulants, antihypertensives and statins) in ten Sub-Saharan African countries. METHODS: Drugs were prospectively collected using standardized methods between 2012 and 2014 from licensed (random pharmacies) and unlicensed (street-markets) places of sale in Africa...

Surrogate-based simulation-optimization technique is an effective approach for optimizing the surfactant enhanced aquifer remediation (SEAR) strategy for clearing DNAPLs. The performance of the surrogate model, which is used to replace the simulation model for the aim of reducing computation burden, is the key of corresponding researches. However, previous researches are generally based on a stand-alone surrogate model, and rarely make efforts to improve the approximation accuracy of the surrogate model to the simulation model sufficiently by combining various methods...

In recent years, considerable efforts have been done to better understand the peculiar emission properties of upconverting materials due to their widespread applications in different and important technological fields such as upconversion-based photoactivated cancer therapies, photoactivated drug-delivery, magnetic resonance imaging contrast agents, bioimaging. However, one of the most promising applications of upconverting materials concerns the field of sensing, due to their unique emission properties. In fact, the minimal autofluorescence, blinking, photo-bleaching, and high photostability makes them an excellent alternative to organic dyes or quantum dots...

Lou Gehrig's disease, a synonym of amyotrophic lateral sclerosis, is an adult-onset lethal neurodegenerative disorder. Irrespective of extensive efforts to elucidate the pathogenesis of the disease and searches for therapies, no favorable pharmacotherapeutic strategies have yet to be proposed. In a popular rodent model of ALS, G93A SOD1 mice, intracellular copper conditions were geared toward copper accumulation inside cells, resulting in an acceleration of oxidative stress and apoptotic process. Disruption of intracellular copper homeostasis was common to transgenic mice expressing human mutant SOD1s...
