Research on community responses to environmental toxicity has richly described the struggles of citizens to identify unrecognized toxins, collect their own environmental health facts, and use them to lobby authorities for recognition and remediation. Much of this literature is based on an empiricist premise: it is concerned with exploring differences in how laypeople and experts perceive what is presumed to be a singular toxic reality that preexists these varying perspectives. Here, we seek to reexamine this topic by shifting the focus from facts to facticity-that is, by exploring the many types of knowledge that communities develop about toxicity and how these knowledges articulate with the ideas of scientific and governmental authorities about what kinds of information are valid bases for policymaking...

Our understanding of the mechanisms that regulate hematopoietic stem/progenitor cells (HSPCs) has been advanced by the ability to genetically manipulate mice; however, germline modification is time consuming and expensive. Here, we describe fast, efficient, and cost-effective methods to directly modify the genomes of mouse and human HSPCs using the CRISPR/Cas9 system. Using plasmid and virus-free delivery of guide RNAs alone into Cas9-expressing HSPCs or Cas9-guide RNA ribonucleoprotein (RNP) complexes into wild-type cells, we have achieved extremely efficient gene disruption in primary HSPCs from mouse (>60%) and human (∼75%)...

New genetic tools are needed to understand the functional interactions between HIV and human host factors in primary cells. We recently developed a method to edit the genome of primary CD4(+) T cells by electroporation of CRISPR/Cas9 ribonucleoproteins (RNPs). Here, we adapted this methodology to a high-throughput platform for the efficient, arrayed editing of candidate host factors. CXCR4 or CCR5 knockout cells generated with this method are resistant to HIV infection in a tropism-dependent manner, whereas knockout of LEDGF or TNPO3 results in a tropism-independent reduction in infection...

Phosphate plays an irreplaceable role in the production of fertilizers. However, its finite availability may not be enough to satisfy increasing demands for the fertilizer production worldwide. In this scenario, phosphate recovery can effectively alleviate this problem. Municipal wastewater has received high priority to recover phosphate because its quantity is considerable. Therefore, phosphate recovery from municipal wastewater can bring many benefits such as relieving the burden of increasing production of fertilizers and reduction in occurrence of eutrophication caused by the excessive concentration of phosphate in the released effluent...

Microfluidics or lab-on-a-chip technology offer clear advantages over conventional systems such as a dramatic reduction of reagent consumption or a shorter analysis time, which are translated into costs effective systems. In this work, we present a photonic enzymatic lab on a chip reactor based on Cross-Linked Enzyme Crystals (CLECs), able to work in continuous flow, as a highly sensitive, robust, reusable and stable platform for continuous sensing with superior performance as compared to the state of the art...

BACKGROUND: About a decade past the first transcatheter aortic valve implantation (TAVI), data are limited regarding temporal trends accompanying its evolution from novel technology to mainstream therapy. We evaluated these trends in a large multicenter TAVI registry. HYPOTHESIS: TAVI is changing and improving with time. METHODS: Patients who underwent TAVI between January 2008 and December 2014 at 3 high-volume Israeli centers were divided into 5 time quintiles according to procedure date...

The past two decades have witnessed a rapid evolution in our ability to measure RNA and protein from biological systems. As a result, new principles have arisen regarding how information is processed in cells, how decisions are made, and the role of networks in biology. This essay examines this technological evolution, reviewing (and critiquing) the conceptual framework that has emerged to explain how RNA and protein networks control cellular function. We identify how future investigations into transcriptomes, proteomes, and other cellular networks will enable development of more robust, quantitative models of cellular behavior whilst also providing new avenues to use knowledge of biological networks to improve human health...

BACKGROUND: Online graduate courses provide opportunities for faculty to use technology and digital applications to enhance student learning and learning environments. In nursing education, as we become increasingly dependent on technology, it is important to ensure that both faculty and students add digital literacy to their repertoire of knowledge and skills. VoiceThread(©), one type of Web-based digital application tool, allows students and faculty to verbally communicate and collaborate asynchronously...

The debate about disability, family and society is an old one. The needs of individuals with disabilities have not been a priority in most societies. However, this population is increasing with the advances in our medical technology and we can no longer ignore them. Overall care, from diagnosis to treatment and integration into society has been fragmented and disorganized. Thus, new thinking about individuals with disabilities has to take place. This article suggests the need for a paradigm shift has to how individuals with disabilities should be viewed and suggests a different model for the development of systems to meet the needs of this growing population...

Individuals with transtibial amputations have difficulties in performing march and stay in balance, directly affecting their quality of life. The use of prostheses can enable the rehabilitation of the individual, but we question how effective are for certain tasks and how they can still improve. To evaluate the prosthesis for transtibial amputation, a comparative study was conducted with two groups: Amputee and NOT Amputees. With the help of Motion Capture technology was held measuring the angles of static balance, walking speed and scores in the execution of daily activities...

The structure of dietary triacylglycerols is thought to influence fatty acid and calcium absorption, as well as intestinal microbiota population of the host. In the present study, we investigated the impact of palmitic acid (PA) esterified at the sn-2 position on absorption of fatty acid and calcium and composition of intestinal microorganisms in rats fed high-fat diets containing either low sn-2 PA (12.1%), medium sn-2 PA (40.4%) or high sn-2 PA (56.3%), respectively. Fecal fatty acid profiles in the soaps were measured by gas chromatography (GC), while fecal calcium concentration was detected by ICP-MS...

Over the last few years, a number of different protein assembly strategies have been developed, greatly expanding the toolbox for controlling macromolecular assembly. One of the most promising developments is a rapid protein ligation approach using a short polypeptide SpyTag and its partner, SpyCatcher derived from Streptococcus pyogenes fibronectin-binding protein, FbaB. To extend this technology, we have engineered and characterized a new Tag-Catcher pair from a related fibronectin-binding protein in Streptococcus dysgalactiae...

Health authorities, medical directors and managers are called to face increasing and inter-related challenges regarding the ongoing financial crisis, aging of the population and the need to acquire innovative medical technologies. These challenges need to be tackled in order to ensure sustainability of the healthcare systems and appropriateness and quality of healthcare services. In Italy, the role of medical directors has progressively evolved over the years and now requires strengthened managerial skills and additional professional expertise and skills to plan, implement and evaluate the new systems of government...

Type II diabetes has a high prevalence rate worldwide, especially in industrialized countries. By requiring increasing health expenditures and resources, the disease and its complications generate a considerable economic burden. Since many years several institutions promote awareness and information programs regarding the most effective strategies to prevent and control diabetes. By reducing the severity of the disease and its complications, Adapted Exercise therapy (AE) represents an ideal instrument to remodulate the Therapeutic Healthcare Management Protocol (THMP) of patients with type II diabetes and may be defined as a new health technology...
