In this paper, we present a soft wearable robot for the shoulder which has the potential to assist individuals suffering from a range of neuromuscular conditions affecting the shoulder to perform activities of daily living. This wearable robot combines two types of soft textile pneumatic actuators which were custom developed for this particular application to support the upper arm through shoulder abduction and horizontal flexion/extension. The advantage of a textile-based approach is that the robot can be lightweight, low-profile, comfortable and non-restrictive to the wearer, and easy to don like an item of clothing...

Understandably, given the fast pace of biodiversity loss, there is much interest in using Earth observation technology to track biodiversity, ecosystem functions and ecosystem services. However, because most biodiversity is invisible to Earth observation, indicators based on Earth observation could be misleading and reduce the effectiveness of nature conservation and even unintentionally decrease conservation effort. We describe an approach that combines automated recording devices, high-throughput DNA sequencing and modern ecological modelling to extract much more of the information available in Earth observation data...

An arbitrarily shaped optical potential on a discrete photonic lattice, which transversely drifts at a speed greater than the maximum speed allowed by the light cone of the lattice band, becomes reflectionless. Such an intriguing result, which arises from the discrete translational symmetry of the lattice, is peculiar to discretized light and does not have any counterpart for light scattering in continuous optical media. A drifting non-Hermitian optical potential of the Kramers-Kronig type also is an invisible potential, i...

Beyond the implementation of the photoacoustic effect to photoacoustic imaging and laser ultrasonics, this study demonstrates a novel application of the photoacoustic effect for high-precision cavitation treatment of tissue using laser-induced focused ultrasound. The focused ultrasound is generated by pulsed optical excitation of an efficient photoacoustic film coated on a concave surface, and its amplitude is high enough to produce controllable microcavitation within the focal region (lateral focus <100 µm)...

AIMS: To elucidate causes and extent of strut malapposition in angiographically optimized stenting. METHODS AND RESULTS: Using a new classification system for strut malapposition, the mechanisms of stent strut malapposition were classified as localized lumen enlargement, vessel asymmetry, stent undersizing, strut underexpansion and stent deployment issue. Stent implantations (n = 110) in 100 consecutive patients undergoing optical coherence tomography (OCT) after the operator considered the stent as optimally deployed angiographically were reviewed to determine if strut apposition was complete...

Non-alcoholic fatty liver disease (NAFLD) affects 20-30% of adults with risk factors like obesity and insulin resistance putatively acting through chronic low-grade inflammation. Because periodontitis elicits low-grade inflammation, we hypothesized that it could contribute to NAFLD occurrence. Objective To investigate epidemiologic associations between periodontitis and the incidence of NAFLD among 2,623 participants of the Study of Health in Pomerania METHODS: Periodontitis at baseline was defined as the percentage of sites (0%, 1-30%, ≥30%) with 1) clinical attachment level (CAL) ≥3mm; 2) probing pocket depth (PD) ≥4mm...

This study investigated ageism among healthcare professionals in various therapeutic settings in Israel. Using a qualitative approach, the current study aimed to examine similarities and differences across healthcare disciplines. Three focus groups were conducted with physicians, nurses, and social workers. Data from each focus group were analyzed separately, and then commonalities and differences across the groups were evaluated. Three main themes relating to older adults emerged from the data. The first theme pertains to perceived difficulties that healthcare professionals experience in working with older adults and their family members; the second focuses on invisibility and discriminatory communication patterns; and the third theme relates to provision of inappropriate care to older adults...

Latently human immunodeficiency virus (HIV)-infected cells are transcriptionally quiescent and invisible to clearance by the immune system. To demonstrate that the latency reversing agent vorinostat (VOR) induces a window of vulnerability in the latent HIV reservoir, defined as the triggering of viral antigen production sufficient in quantity and duration to allow for recognition and clearance of persisting infection, we developed a latency clearance assay (LCA). The LCA is a quantitative viral outgrowth assay (QVOA) that includes the addition of immune effectors capable of clearing cells expressing viral antigen...

The University of Québec in Montréal has agreements with trade unions providing access to university resources. Researchers involved in this program worked in partnership with union women's and health and safety committees for more than twenty years. Not all studies succeeded in improving women's working conditions. One joint project involved observational studies of tasks done by health-care workers, complemented by interviews and questionnaires. We found that task assignments, movements, postures, and work-related musculoskeletal disorders varied by gender/sex and made recommendations for change...

The work of Jacques Derrida has received relatively little attention within nursing philosophy. Perhaps this is because Derrida is known best for deconstructing philosophy itself, a task he performed by making language unintelligible to make a point. This in itself makes his work daunting for nurses who do applied philosophy. Despite these difficulties, Derrida's focus on holding open a space for ideas, particularly those ideas that are invisible or unpopular, holds potential for enhancing the diversity of ideas within nursing...

OBJECTIVES: The aim of this study was to evaluate optical coherence tomography (OCT) and intravascular ultrasound (IVUS) versus coronary angiography in the assessment of target lesion calcification and its effect on stent expansion. BACKGROUND: IVUS is more sensitive than angiography in the detection of coronary artery calcium, but the relationship among IVUS, OCT, and angiography has not been studied. METHODS: Overall, 440 lesions (440 patients with stable angina) underwent OCT- and IVUS-guided stent implantation...

Non-Hermitian degeneracies, also known as exceptional points, have recently emerged as a new way to engineer the response of open physical systems, that is, those that interact with the environment. They correspond to points in parameter space at which the eigenvalues of the underlying system and the corresponding eigenvectors simultaneously coalesce. In optics, the abrupt nature of the phase transitions that are encountered around exceptional points has been shown to lead to many intriguing phenomena, such as loss-induced transparency, unidirectional invisibility, band merging, topological chirality and laser mode selectivity...

Fatigue is a symptom experienced almost universally by people living with a chronic illness. People diagnosed with heart failure have described experiencing significant levels of fatigue. The family experience of fatigue, that is, how families perceive, respond to, and manage fatigue, is unknown. Semistructured family group interviews with 22 families ( N = 62 family members) were conducted. Thematic analysis was undertaken to explore the family experience of fatigue. Fatigue was described as a significant symptom that affected physical, emotional, and social functioning at a family level...

OBJECTIVE: Bacteria in chronic wounds are invisible to the naked eye and can lead to delayed wound healing. Point-of-care bacterial fluorescence imaging illuminates a wound with 405nm light, triggering bacteria to produce red fluorescence and enabling real-time bacterial localisation. Prospective, single-blind clinical trials (clinicaltrials.gov #NCT02682069, #NCT03091361) were conducted to determine the positive predictive value (PPV) of this red fluorescence for detecting bacteria in chronic wounds...

The ocular surface is comprised of the cornea and conjunctiva, which are structures that not only protect the eye but also enable vision. The corneal epithelium is the most superficial layer of the cornea, and therefore first line of defense against external assaults. Damage to this highly specialized structure could lead to vision loss, making it an important structure to investigate and understand. Here, we conducted a search of the current literature on the mechanisms the corneal epithelium has adapted against three frequent insults: UV-radiation, pathogens, and environmental assaults...

Science and Technology Studies has become increasingly interested in the roles of affect and emotions in science and technology. Researchers have examined, for example, emotions in the production of scientific knowledge, patients' or users' affective experiences of technologies, and emotionally charged cultural representations of science. However, less attention has been paid to the underlying affective dynamics that connect these sites, experiences and representations. This article builds on the premises that, first, unpacking these underlying affective dynamics is pivotal to understanding emerging technoscientific phenomena, and, second, that such affective dynamics often need to be accessed through cultural texts such as media...

BACKGROUND: The orthodontics industry has paid great attention to the aesthetics of orthodontic appliances, seeking to make them as invisible as possible. There are several advantages to clear aligner systems, including aesthetics, comfort, chairside time reduction, and the fact that they can be removed for meals and oral hygiene procedures. METHODS: Five patients were each given a series of F22 aligners, each to be worn for 14 days and nights, with the exception of meal and brushing times...
