Doctor-patient conflicts in contemporary China are increasing in numbers and severity. This health geographic study shows how hospitals as a type of therapeutic landscape can shape doctor-patient relationships. First, the comprehensive nature of therapeutic landscapes with an emphasis on power operation within symbolic environments is provided as a framework for this study. Second, the results from participant observation and interviews with patients and doctors previously involved in conflicts are reported from Internal Medicine and Surgery Departments, within four hospitals in Anhui Province, Eastern China...

Recently, independent components analysis (ICA) of resting state magnetoencephalography (MEG) recordings has revealed resting state networks (RSNs) that exhibit fluctuations of band-limited power envelopes. Most of the work in this area has concentrated on networks derived from the power envelope of beta bandpass-filtered data. Although research has demonstrated that most networks show maximal correlation in the beta band, little is known about how spatial patterns of correlations may differ across frequencies...

OBJECTIVE: To determine how care home managers negotiate the conflict between maintaining a safe environment while enabling the autonomy of residents with dementia. This is important because there is limited research with care home managers; yet, they are key agents in the implementation of national policies. METHOD: Semi-structured interviews were conducted with 18 managers from care homes offering dementia care in the Northwest of England. Data were analysed using a thematic analysis approach...

Owing to their ability to act as light-harvesting scaffolds, porphyrin-containing metal-organic frameworks (MOFs) are in the forefront of research on the application of highly ordered molecular materials to problems in solar-energy conversion. In this work, solvent assisted linker exchange (SALE) is performed on a pillared paddlewheel porphyrin containing MOF thin film to collapse a 3D-framework to a 2D-framework. The change in dimensionality of the framework is confirmed by a decrease in the film thickness, the magnitude of which is in agreement with crystallographic parameters for related bulk materials...

Biosafety level 4 (BSL-4) suit laboratories are specifically designed to study high-consequence pathogens for which neither infection prophylaxes nor treatment options exist. The hallmarks of these laboratories are: custom-designed airtight doors, dedicated supply and exhaust airflow systems, a negative-pressure environment, and mandatory use of positive-pressure ("space") suits. The risk for laboratory specialists working with highly pathogenic agents is minimized through rigorous training and adherence to stringent safety protocols and standard operating procedures...

Values are a central personality construct and the importance of studying them has been well established. To encourage researchers to integrate measures of values into their studies, brief and ultrabrief instruments were developed to recapture the 10 values measured by the 40-item Portrait Values Questionnaire (PVQ; Schwartz, 2003 ). Rigorous psychometric procedures based on separate derivation (N = 38,049) and evaluation (N = 29,143) samples yielded 10- and 20-item measures of values, which proved to be successful at capturing the patterns and magnitude of correlations associated with the original PVQ...

BACKGROUND: Automated skin lesion border examination and analysis techniques have become an important field of research for distinguishing malignant pigmented lesions from benign lesions. An abrupt pigment pattern cutoff at the periphery of a skin lesion is one of the most important dermoscopic features for detection of neoplastic behavior. In current clinical setting, the lesion is divided into a virtual pie with eight sections. Each section is examined by a dermatologist for abrupt cutoff and scored accordingly, which can be tedious and subjective...

BACKGROUND: The amount of scientific information about MicroRNAs (miRNAs) is growing exponentially, making it difficult for researchers to interpret experimental results. In this study, we present an automated text mining approach using Latent Semantic Indexing (LSI) for prioritization, clustering and functional annotation of miRNAs. RESULTS: For approximately 900 human miRNAs indexed in miRBase, text documents were created by concatenating titles and abstracts of MEDLINE citations which refer to the miRNAs...

To survive exposure to space conditions, organisms should have certain characteristics including a high tolerance for freezing, radiation and desiccation. The organisms with the best chance for survival under such conditions are extremophiles, like some species of Bacteria and Archea, Rotifera, several species of Nematoda, some of the arthropods and Tardigrada (water bears). There is no denying that tardigrades are one of the toughest animals on our planet and are the most unique in the extremophiles group...

Aim. Purpose of the present paper is to analyze the efficiency of different post-space irrigation protocols. Methods. 28 single rooted teeth were endodontically treated. After post-space preparation every sample was assigned to one of three experimental groups and to one control group. In each group different irrigation protocols were performed as follows: EDTA (Group A), 37% orthophosphoric acid (Group B), and EDTA + 37% orthophosphoric acid with ultrasounds activation (Group C). In the control group (Group D) the irrigate association was not activated by ultrasounds...

The fossils from Malapa cave, South Africa, attributed to Australopithecus sediba, include two partial skeletons-MH1, a subadult, and MH2, an adult. Previous research noted differences in the mandibular rami of these individuals. This study tests three hypotheses that could explain these differences. The first two state that the differences are due to ontogenetic variation and sexual dimorphism, respectively. The third hypothesis, which is relevant to arguments suggesting that MH1 belongs in the genus Australopithecus and MH2 in Homo, is that the differences are due to the two individuals representing more than one taxon...

The UK's Quality and Outcomes Framework (QOF) is the largest pay-for-performance scheme in the world. This ethnographic study explored how QOF's monetary logic influences the approach to healthcare in UK general practice. From August 2013 to April 2014, we researched two UK general practice surgeries and one general practice training programme. These environments provided the opportunity for studying various spaces such as QOF meetings, consultation rooms, QOF recoding sessions, and the collection of computer-screen images depicting how patients' biomarkers are evaluated and costed through software systems...

Synthetic experimental substrates are indispensable tools which can allow researchers to model biological processes non-invasively in three-dimensional space. In this study, we investigated the capacities of an electroconductive material whose properties converge upon those of the brain. An electrically conductive material composed of carbohydrates, proteins, fats, ions, water, and trace amounts of other organic compounds and minerals was classically conditioned as inferred by electrophysiological measurements...

INTRODUCTION: Exposure to secondhand smoke is problematic for residents living in multiunit housing, as the smoke migrates through shared ventilation systems, unsealed cracks, and door spaces. The objective of our research was to assess resident exposure to secondhand smoke, support for no-smoking policies, and the health impacts of no-smoking policies in multiunit housing. METHODS: Surveys of 312 heads of households who resided in 1 of 3 multiunit buildings managed by a Colorado public housing authority were administered before and after implementation of a no-smoking policy that prohibited smoking in all resident apartments and all indoor common areas...

This paper focuses on the shift that occurred in the spatial representation of states in the eighteenth century. This shift will be considered as a combination of institutional reforms and of a new social awareness of space. A consideration of the case of the Italian Piedmont will demonstrate how "national" space was created through antiquarian research and how a larger political confrontation took place in the guise of a learned debate. The diverse accounts of Piedmontese history under examination all employed methods derived from previous ages, relying upon a concept of space as historically continuous, embedded in time immemorial...

The year 2016 witnesses the 150th anniversary of laying the first successful transatlantic telegraph cables. This review essay offers a critical rereading of existing scholarship while simultaneously suggesting new perspectives for research. Telegraphy = globalization, the history of wiring the world commencing with the Atlantic cable of 1866 seems to suggest. At the same time, this essay argues, this equation should make scholars uneasy and cautious of a possible technological determinism retracing its steps back into the middle of scholarly debates on globalization...

NF-κB is a family of ubiquitous dimeric transcription factors that play a role in a myriad of cellular processes, ranging from differentiation to stress response and immunity. In inflammation, activation of NF-κB is mediated by pro-inflammatory cytokines, in particular the prototypic cytokines IL-1β and TNF-α, which trigger the activation of complex signaling cascades. In spite of decades of research, the system level understanding of TNF-α signaling is still incomplete. This is partially due to the limited knowledge at the proteome level...

In 1992, the Brugada syndrome (BrS) was recognized as a disease responsible for sudden cardiac death, characterized by a right bundle-branch block with ST segment elevation in the leads V1 and V2. This syndrome is highly associated with sudden cardiac death, especially in young males. BrS is currently diagnosed in patients with ST-segment elevation showing type 1 morphology ≥ 2 mm in ≥1 leads among the right precordial leads V1 or V2 positioned in the 2nd, 3rd, or 4th intercostal space, and occurring either spontaneously or after a provocative drug test by the intravenous administration of Class I antiarrhythmic drugs...
