BACKGROUND: To investigate the agreement between Kupffer phase of Sonazoid contrast-enhanced sonography (CEUS) and hepatobiliary phase of gadoxetic acid-enhanced MRI in the evaluation of focal liver lesions (FLLs). METHODS: One hundred fifty-four FLLs in 154 patients who underwent both Sonazoid CEUS and gadoxetic acid-enhanced liver MRI were included in this retrospective study. FLL visibility on the Kupffer-phase images was graded as one (invisible or isoenhancing), two (vaguely visible or vaguely hypoenhancing), or three (clearly visible or clearly hypoenhancing), and that on the hepatobiliary-phase images of MRI was graded as one (invisible or hyper/isointense), two (vaguely visible or weakly hypointense), or three (clearly visible or strongly hypointense)...

Low-dimensional carbon materials, such as semiconducting carbon nanotubes (CNTs), conducting graphene, and their hybrids, are of great interest as promising candidates for flexible, foldable, and transparent electronics. However, the development of highly photoresponsive, flexible, and transparent optoelectronics still remains limited due to their low absorbance and fast recombination rate of photoexcited charges, despite the considerable potential of photodetectors for future wearable and foldable devices...

BACKGROUND: As a result of restructuring, home care is increasingly defined in a narrow, task-based way, undermining the holistic nature of practice. Recent practice theories can aid us in articulating the nature of this important, yet often invisible practice. AIM: My aim in this article was to enhance our knowledge and understanding of the nature of home care nursing practice. METHOD: The approach was ethnographic, involving extensive fieldwork and formal interviews with members of five home care nursing teams and 15 older persons receiving care at home in a metropolitan area of Iceland...

We examined the recently discovered phenomenon of Adaptation-Induced Blindness (AIB), in which highly visible gratings with gradual onset profiles become invisible after exposure to a rapidly flickering grating, even at very high contrasts. Using very similar stimuli to those in the original AIB experiment, we replicated the original effect across multiple contrast levels, with observers at chance in detecting the gradual onset stimuli at all contrasts. Then, using full-contrast target stimuli with either abrupt or gradual onsets, we tested both the orientation tuning and interocular transfer of AIB...

BACKGROUND: There is little research regarding how everyday life is affected by colon cancer treatment. Few studies exist that exclusively examine patients with Dukes C colon cancer. Most studies include other types of bowel cancer and different stages. OBJECTIVES: The aims of this study were to explore and describe how colon cancer survivors experience everyday life in general and sexuality in particular after treatment of Dukes C colon cancer. METHODS: The study is exploratory and descriptive and uses semistructured interviews to collect data...

Human coronavirus (CoV) HKU1 is a pathogen causing acute respiratory illnesses and so far little is known about its biology. HKU1 virus uses its S1 subunit C-terminal domain (CTD) and not the N-terminal domain like other lineage A β-CoVs to bind to its yet unknown human receptor. Here we present the crystal structure of HKU1 CTD at 1.9 Å resolution. The structure consists of three subdomains: core, insertion and subdomain-1 (SD-1). While the structure of the core and SD-1 subdomains of HKU1 are highly similar to those of other β-CoVs, the insertion subdomain adopts a novel fold, which is largely invisible in the cryo-EM structure of the HKU1 S trimer...

Melanopsin photoreception enhances retinal responses to variations in ambient light (irradiance) and drives non-image-forming visual reflexes such as circadian entrainment [1-6]. Melanopsin signals also reach brain regions responsible for form vision [7-9], but melanopsin's contribution, if any, to encoding visual images remains unclear. We addressed this deficit using principles of receptor silent substitution to present images in which visibility for melanopsin versus rods+cones was independently modulated, and we recorded evoked responses in the mouse dorsal lateral geniculate nucleus (dLGN; thalamic relay for cortical vision)...

Hyeonbin Ryoo, Wonju Jeon
During the last decade, most of acoustic cloak research has been done within a theoretical framework in which the medium is at rest. However, such an acoustic cloak cannot preserve its unique properties or functions to make an object acoustically invisible in the presence of flow. In this study, we propose a theoretical framework to accurately investigate the effect of compressibility and non-uniformity in flow on the scattering pattern of acoustic cloak. In the formulation, the wave operator is coupled with the non-uniform velocity vector, and the equivalent source terms due to mean flow are divided into the compressibility effect and the non-uniformity effect with their own physical meanings...

Protein ADP-ribosylation (ADPr), a biologically and clinically important post-translational modification, exerts its functions by targeting a variety of different amino acids. Its repertoire recently expanded to include serine ADPr, which is emerging as an important and widespread signal in the DNA damage response. Chemically, serine ADPr (and more generally o-glycosidic ADPr) is a form of o-glycosylation, and its extreme lability renders it practically invisible to standard mass spectrometry approaches, often leading to erroneous localizations...

The aim of this study was to document the detailed anatomy of neural course and distribution on the anterior ascending aorta, to identify the high and low density areas of the anterior ascending aortic plexus for further understandings in cardiovascular surgery. The embalmed hearts of 42 elderly individuals were submacroscopically and microscopically examined, after excluding any that were macroscopically abnormal. With its origins in the anterior ascending aortic plexus, the right coronary plexus substantially innervated the right coronary artery, the right atrium and ventricle, and the sinus node...

The present study was designed to tackle two notorious features of mild Traumatic Brain Injury (mTBI) - heterogeneity and invisibility - by characterizing the full scope of mTBI symptoms. Mice were exposed to brain injuries of different intensities utilizing a weight-drop model (10, 30, 50, and 70g), and subsequently subjected to a comprehensive battery of behavioral tests at different time points, and immunohistochemical examination of cortical slices. While the physiological, neurological, emotional, and motor function of mTBI mice, i...

OBJECTIVES: To clarify the depression aspect of the maxillary sinus anterior wall, and to investigate its relationship with the panoramic image appearance of a diagonal line from the inferior part of the so-called panoramic innominate line to the medial portion of the orbital floor line. METHODS: Based on computed tomographic (CT) data, panoramic images were simulated for two typical cases with and without anterior wall depression. Next, on axial CT images of 1689 subjects (3378 sinuses) stored in our image database, the wall depths were measured and analyzed for their relationships with the panoramic appearances of the diagonal line, classified into invisible, obscure, and clear patterns...

Sexual minority health is increasingly receiving attention by health sciences education and healthcare, with the core argument being that health can be improved by challenging sexual minority invisibility. Invisibility as a concept, however, does not allow for a deeper theoretical engagement with the reasons and consequences of the lack of representation of queerness in healthcare. Drawing on empirical research with queer healthcare users in South Africa, I argue that 'invisibility' actually encompasses two distinct, though related, concepts: queer symbolic annihilation as the reason for the exclusion of queer identities in health professions education and, by consequence, in healthcare; and queer (un)intelligibility as the consequence of this systemic erasure...

Corneal transplantation (keratoplasty) is the most frequently performed form of transplantation worldwide. A rejection reaction against the transplant is the main complication occurring after transplantation in an already vascularized, so-called "high-risk" recipient eye. Our group has shown that clinically invisible lymphatic vessels play a crucial role in the induction of a rejection reaction against the corneal graft, and that anti-(lymph)angiogenic therapies in the mouse model of keratoplasty can significantly improve transplant survival...

Within the range of validity of the stationary diffusion equation, an ideal diffusive-light invisibility cloak can make an arbitrary macroscopic object hidden inside of the cloak indistinguishable from the surroundings for all colors, polarizations, and directions of incident visible light. However, the diffusion equation for light is an approximation which becomes exact only in the limit of small coherence length. Thus, one expects that the cloak can be revealed by illumination with coherent light. The experiments presented here show that the cloaks are robust in the limit of large coherence length but can be revealed by analysis of the speckle patterns under illumination with partially coherent light...

This article probes how childhood experiences are actively taken into adult lives and thus challenges the unwitting and unintentional reproduction of an adult-child binary in childhood studies. We do this by analyzing interviews with one adult daughter of immigrants from Mexico to the United States at four points in time (ages 19, 26, 27, and 33). Using narrative analysis to examine the mutability of memory, we consider how Eva oriented herself to her childhood story, what was salient and invisible in each recount, the values she associated with the practice, and the meanings she took from her experiences...
