As rechargeable Li-ion batteries have expanded their applications into onboard energy storage for electric vehicles, the energy and power must be increased to meet the new demands. Li-rich layered oxides are one of the most promising candidate materials, however, they are very difficult to be compatible with high volumetric energy density and power density. Here we develop an innovative approach to synthesize three dimensional (3D) nanoporous Li-rich layered oxides Li[Li0.144Ni0.136Co0.136Mn0.544]O2, directly occurring at deep chemical delithiation with carbon dioxide...

This study aims to (1) investigate the neuropathology of mild to severe pediatric TBI and (2) elucidate the predictive value of conventional and innovative neuroimaging for functional outcome. Children aged 8-14 years with trauma control (TC) injury (n = 27) were compared to children with mild TBI and risk factors for complicated TBI (mild(RF+), n = 20) or moderate/severe TBI (n = 17) at 2.8 years post-injury. Neuroimaging measures included: acute computed tomography (CT), volumetric analysis on post-acute conventional T1-weighted magnetic resonance imaging (MRI) and post-acute diffusion tensor imaging (DTI, analyzed using tract-based spatial statistics and voxel-wise regression)...

Diffusion-weighted magnetic resonance imaging is a non-invasive imaging method that has been increasingly used in neuroscience imaging over the last decade. Partial volume effects (PVEs) exist in sampling signal for many physical and actual reasons, which lead to inaccurate fiber imaging. We overcome the influence of PVEs by separating isotropic signal from diffusion-weighted signal, which can provide more accurate estimation of fiber orientations. In this work, we use a novel response function (RF) and the correspondent fiber orientation distribution function (fODF) to construct different signal models, in which case the fODF is represented using dictionary basis function...

Tioconazole-loaded nanocapsule suspensions and its coating with a cationic polymer were developed for nail drug delivery. The colloidal systems presented a nanometric size around 155nm for uncoated nanoparticles and 162nm for those with the cationic coating, with negative and positive zeta potential values, respectively. Both nanosuspensions showed drug content close to theoretical values (1mgmL(-1)), association efficiency close to 100% (HPLC) and were able to control tioconazol release. The developed formulations showed in vitro antifungal activity (agar diffusion method) against C...

INTRODUCTION: Pain treatment is best performed when a patient-centric, safety-based philosophy is used to determine an algorithmic process to guide care. Since 2007, the International Neuromodulation Society has organized a group of experts to evaluate evidence and create a Polyanalgesic Consensus Conference (PACC) to guide practice. METHODS: The current PACC update was designed to address the deficiencies and innovations emerging since the previous PACC publication of 2012...

Neuroendocrine differentiation of prostate cancer (PCa) is a relatively frequent event, generally understudied, that carries important prognostic information. It is most frequently observed during the advanced stages of disease, when PCa has lost its sensitivity to androgen deprivation therapy or to chemotherapy, moderate to diffuse bone metastatic spread dominates the imaging scenario and it is responsible for painful clinical symptomatology. However, evidences indicate that neuroendocrine differentiation is a progressive phenomenon that starts at the very early part of the pathogenesis of cancer transformation contributing to it...

Technological innovation in healthcare yields better health outcomes but also drives healthcare expenditure, and governments are struggling to maintain an appropriate balance between patient access to modern care and the economic sustainability of healthcare systems. Health Technology Assessment (HTA) and centralized procurement are increasingly used to govern the introduction and diffusion of new technologies in an effort to make access to innovation financially sustainable. However, little empirical evidence is available to determine how they affect the selection of new technologies and unit prices...

We conduct a series of simulations to compare how various strategies for seeding a policy in the American states affect the rate at which that policy spreads. Using empirically derived parameters of the policy diffusion process, we simulate the diffusion of a hypothetical policy after seeding the policy in just a handful of states. We compare these strategies to those in the ten states the RWJF monitored during the states' implementation of the Affordable Care Act of 2010. We attempt to mimic the choices that policy advocates make when deciding which states to target with their resources...

Because numerous barriers hinder the assessment and management of chemotherapy-induced peripheral neuropathy in clinical practice, the Carevive Care Planning System, a novel Web-based platform, was developed to address these barriers. It provides patients an opportunity to report their symptoms before their clinic visit and generates customizable care plans composed of evidence-based management strategies. The purpose of this study was to evaluate patient and provider perspectives of feasibility, usability, acceptability, and satisfaction with the Carevive platform...

The internet facilitates rapid and covert communication, knowledge transfer, and has the potential to disrupt and transform drug market models and associated consumption patterns. Innovation and new trends diffuse rapidly through this medium and new operational models are emerging. Although the online drug markets currently only account for a small share of all drug transactions, the potential of the surface and deep web to provide a new platform for drug sale and exchanges is considerable.

The diamondback moth (Plutella xylostella) is a major pest of broccoli crops in Colombia. To control P. xylostella, we evaluated the interaction of Beauveria bassiana Bb9205 and Metarhizium anisopliae Ma9236 with Heterorhabditis bacteriophora HNI0100 and its bacterial symbiont Photorhabdus luminescens HNI0100. We used antagonism and disk diffusion assays with fungal extracts to test the interaction between symbiotic bacterium and fungi. P. luminescens inhibited the growth of B. bassiana and M. anisopliae up to 40% by the secretion of secondary metabolites, whereas fungal extracts did not inhibit P...

The need to develop effective and efficient strategies for the dissemination of evidence-based health care has been recognized by governments, researchers, and clinicians alike. However, recognition and implementation are separate issues. If scientists are to have a significant impact on clinical practice, they will have to learn a new way of "doing business." Lessons from the business community and from the field of diffusion of innovations research (dissemination research) have direct applicability to disseminating science-based clinical procedures...

Cerebrovascular diseases are one of the most common causes of secondary movement disorders. Hypokinetic or hyperkinetic movement disorders may occur after an ischemic or hemorrhagic stroke, either immediately or thereafter. Such disorders are also known to be caused by diffuse leukoaraiosis, vascular malformations and dural fistulas in the basal ganglia or other brain regions. Area covered: The aim of this review was to describe movement disorders secondary to cerebrovascular diseases, and highlight their pivotal pathophysiological aspects, clinical features, diagnostic criteria and therapeutic options...

The original four-stage model of the cigarette epidemic has been extended with diffusion of innovations theory to reflect socio-economic differences in cigarette use. Recently, two revisions of the model have been proposed: (1) separate analysis of the epidemic stages for men and women, in order to improve generalization to developing countries, and; (2) addition of a fifth stage to the smoking epidemic, in order to account for the persistence of smoking in disadvantaged social groups. By developing a cohort perspective spanning a 35-year time period in France and the USA, we uncover distinctive features which challenge the currently held vision on the evolution of smoking inequalities within the framework of the cigarette epidemic...
