Modern challenges require new approaches to urban water management. One solution in the portfolio of potential strategies is the integration of distributed water infrastructure, practices, and technologies into existing systems. However, many practical barriers have prevented the widespread adoption of these systems in the US. The objective of this paper is to address these challenges by developing a conceptual model encompassing regulatory, financial, and governance components that can be used to incorporate new distributed water solutions into our current network...

Tissue and biomedical engineering fields are in constant mutation and in searching for innovative processing techniques capable to tailor the material properties. In this work, poly(l-lactic acid) (PLLA) and elastomeric poly(glycerol sebacate) (PGS) were dissolved in the same solvents and electrospun together, in a single needle system. A core-shell structure where the hydrophilic PGS was placed onto the surface of the hydrophobic PLLA fibre was obtained for elastomeric concentrations up to 25wt%. It was found that the PLLA:PGS blends are immiscible and the blends present the melting temperatures of the individual polymers...

Big Data analysis has become a key factor of being innovative and competitive. Along with population growth worldwide and the trend aging of population in developed countries, the rate of the national medical care usage has been increasing. Due to the fact that individual medical data are usually scattered in different institutions and their data formats are varied, to integrate those data that continue increasing is challenging. In order to have scalable load capacity for these data platforms, we must build them in good platform architecture...

Advances in robotic medicine have been adopted by various surgical subspecialties as the benefits of this technology become more readily apparent: precision in narrow operative windows, tremor controlled movements, and modestly improved outcomes, among others. Vascular neurosurgery, in particular, remains open to newer and more cutting edge treatment options for complex pathologies, and robotics may be on the horizon for such advances. We seek to provide a broad overview of these innovations in vascular neurosurgery for both practitioners well acquainted with robotics and those seeking to become more familiar...

Aneuploidy, a condition of unbalanced chromosome content, represents a large-effect mutation that bears significant relevancy to human health and microbe adaptation. As such, extensive studies of aneuploidy have been conducted in unicellular model organisms and cancer cells. Aneuploidy also frequently is associated with plant polyploidization, but its impact on gene expression and relevance to polyploid genome evolution/functional innovation remain largely unknown. Here, we used a panel of diverse types of whole-chromosome aneuploidy of hexaploid wheat, all under the common genetic background of cv...

Highly hydrophilic and biocompatible nanocarriers based on polysaccharide hydrogels (nanohydrogels, NHs) were shown to be promising systems for drug delivery applications. Following the idea of these emerging drug carriers, the aim of the present work was to develop self-assembled hydrogel nanoparticles based on amphiphilic derivatives of hyaluronic acid (HA) and riboflavin (Rfv), synthesized by "click" Copper(I)-catalyzed Azide-Alkyne Cycloaddition (CuAAC) reaction. The obtained amphiphilic product (HA-c-Rfv) was able to form nanohydrogels in aqueous environments, in particular by applying an innovative autoclave-based method...

The present contribution aims at describing the fabrication of coacervates in the nano-size range starting from a 1-deoxylactit-1-yl chitosan (in this manuscript termed as CTL60) and the multivalent anion tripolyphosphate (TPP). Colloidal coacervates have been obtained for precise values of the molar ratio of TPP to CTL60 repeating unit. Coacervation is ensured only at pH 4.5 and not at 7.4, thus demonstrating the key role of electrostatic interactions in the stabilization of the coacervates. At a variance with chitosan, CTL60 favors the formation of highly homogeneous coacervates with very low values of the polydispersity index (PDI)...

Improving natural pest control by promoting high densities of predatory mites (Acari: Phytoseiidae) is an effective way to prevent damage by pest mites (e.g., Eriophyidae, Tetranychidae) and other arthropod taxa that can cause serious damage to vineyards. Here, we investigate the influence of innovative management on predatory mite densities. We compare (i) full versus reduced fungicide applications and (ii) minimal pruning versus a traditional trellis pruning system in four fungus-resistant grapevine varieties...

Skeletal deformity and bone fragility are the hallmarks of the brittle bone dysplasia osteogenesis imperfecta. The diagnosis of osteogenesis imperfecta usually depends on family history and clinical presentation characterized by a fracture (or fractures) during the prenatal period, at birth or in early childhood; genetic tests can confirm diagnosis. Osteogenesis imperfecta is caused by dominant autosomal mutations in the type I collagen coding genes (COL1A1 and COL1A2) in about 85% of individuals, affecting collagen quantity or structure...

Biomimetics, the transfer of functional principles from living systems into product designs, is increasingly being utilized by engineers. Nevertheless, recurring problems must be overcome if it is to avoid becoming a short-lived fad. Here we assess the efficiency and suitability of methods typically employed by examining three flagship examples of biomimetic design approaches from different disciplines: (1) the creation of gecko-inspired adhesives; (2) the synthesis of spider silk, and (3) the derivation of computer algorithms from natural self-organizing systems...

Terry Judd, Anna Ryan, Eleanor Flynn, Geoff McColl
Large-scale interview and simulation-based assessments such as objective structured clinical examinations (OSCEs) and multiple mini interviews (MMIs) are logistically complex to administer, generate large volumes of assessment data, and are strong candidates for the adoption of computer-based marking systems. Adoption of new technologies can be challenging, and technical failures, which are relatively commonplace, can delay and/or create resistance to ongoing implementation.This paper reports on the adoption process of an electronic marking system for OSCEs and MMIs following an unsuccessful initial trial...

Health care professionals involved in the clinical management of children have long appreciated the limited number of therapies suitably evaluated for their optimal use in the pediatric population. In the past century, advances in regulatory policy significantly evolved adult drug evaluation. The scarcity of available patient populations, practical complexities of drug development research, and minimal financial returns have hampered pharmaceutical investment in the study of therapies for children. More recently, pediatric policy and legislation in the United States and Europe have instituted a system of obligations and incentives to stimulate investment in pediatric drug development...

Functional dyspepsia is a highly prevalent disease, with significant impacts on patients' quality of life and economic robustness of health care systems worldwide. It constitutes a constellation of symptoms located in the gastro duodenal region while its pathogenesis remains poorly understood. Accumulating evidence suggest that small intestinal bacterial overgrowth is associated with the etiology of functional gastrointestinal disorders. We herein present the hypothesis that a causal link between small intestinal bacterial overgrowth and functional dyspepsia might exist...

The development of in vitro protein misfolding amplification assays for the detection and analysis of abnormally folded proteins, such as proteinase K resistant prion protein (PrP(res)) was a major innovation in the prion field. In prion diseases, these types of assays imitate the pathological conversion of the cellular PrP (PrP(C)) into a proteinase resistant associated conformer or amyloid, called PrP(res). Areas covered: The most prominent protein misfolding amplification assays are the protein misfolding cyclic amplification (PMCA), which is based on sonication and the real-time quaking-induced conversion (RT-QuIC) technique based on shaking...
