Sexual relationship after surgical menopause matters when talking about sex is taboo and marriage is the only justified way to meet sexual needs. In this qualitative research approach 22 surgical menopausal women shared their experiences of sexual/ marital relationship after surgery through in-depth, face-to-face and semi-structured interviews. Qualitative content analysis technique was used for data analysis. An overarching theme entitled "feeling an invisible wall" reflected this experience. It comprised of three categories: 1) Declined marital intimacy, 2) Disarming, and 3) Transformation of social norms into concerns...

Visual perception includes ventral and dorsal stream processes. However, it is still unclear whether the former is predominantly related to conscious and the latter to nonconscious visual perception as argued in the literature. In this study upright and inverted body postures were rendered either visible or invisible under continuous flash suppression (CFS), while brain activity of human participants was measured with functional MRI (fMRI). Activity in the ventral body-sensitive areas was higher during visible conditions...

Pain is difficult to communicate and translate into language, yet most social research on pain experience uses questionnaires and semi-structured interviews that rely on words. In addition to the mind/body dualism prevalent in pain medicine in these studies pain communication is characterised by further value-laden binaries such as real/unreal, visible/invisible, and psychological/physical. Starting from the position that research methods play a role in constituting their object, this article examines the potential of participatory arts workshops for developing different versions of pain communication...

In a given year, around 25% of the Dutch population may experience significant mental health problems, much more than the mental health service can attend to, given a maximum capacity of 6% of the population per year. Due to the lack of a public mental health system, there is fierce competition over who gets to receive care from mental health services and little control over how the level of needs can be matched with the appropriate intensity of care. As a result, resources are being wasted and both overtreatment and undertreatment are prevalent...

We use the language of uninformative Bayesian prior choice to study the selection of appropriately simple effective models. We advocate for the prior which maximizes the mutual information between parameters and predictions, learning as much as possible from limited data. When many parameters are poorly constrained by the available data, we find that this prior puts weight only on boundaries of the parameter space. Thus, it selects a lower-dimensional effective theory in a principled way, ignoring irrelevant parameter directions...

Anthocyanin-rich purple corn pericarp water extract (PCW) has the potential to be used as a natural pigment in beverages. However, it has a limited shelf-life in aqueous solutions. The aim was to evaluate the effect of zinc ion (Zn2+) and alginate on color and chemical stability of anthocyanins from colored corn (PCW) in a beverage model for 12weeks. PCW was incorporated to Kool-Aid® Invisible™ along with ZnCl2 and/or alginate. Individual ANC were quantified through HPLC, and color stability was evaluated through the CIE-L*a*b* color system...

Migration and the current European socioeconomic conditions necessitate an evaluation/assessment, as detailed as possible, of the spread of seasonal infectious diseases in order to reduce inequalities in the healthcare system. The "Scuola di Formazione in Medicina Generale" of Lazio, in collaboration with the Community of Sant'Egidio of Rome, organized an influenza/flu vaccination campaign for homeless people, migrants and the poor in order to check their health conditions and prevent the spread of the most common infectious diseases...

The discovery that green fluorescent protein from Aequorea Victoria (GFP) could be exogenously expressed in other organisms in 1994 revolutionized biological and biomedical research[1]. Ever since, the toolbox of fluorescent proteins (FPs) has constantly grown comprising many color variants covering the visible and near infrared spectrum (reviewed in [2]). Furthermore, photochromic proteins have been identified that can reversibly or irreversibly change their spectral properties upon light illumination (reviewed in [3,4])...

Forensic science is increasingly used to help exonerate the innocent and establishing links between individuals and criminal activities. With increased reliance on scientific services provided by multi-disciplinary (police, medicine, law, forensic science), and multi-organisational in the private and government sectors (health, justice, legal, police) practitioners, the potential for miscommunication resulting unjust outcomes increases. The importance of identifying effective multi-organisational information sharing is to prevent the 'justice silo effect'; where practitioners from different organisations operate in isolation with minimal or no interaction...

The aim of this study is to present concrete descriptions of the content in the construction of helpful relationships with staff, according to users. Starting with the re-occurring concept of the meaning of "little things" in recovery studies, a literature review was done. A thematic analysis shows that small things play an important role in improving a person's sense of self. Small things seem to be an invisible but effective parts of a recovery-orientated practice, but they might be defined as unprofessional and their efficacy negated...

Using state of the art scanning transmission electron microscopy (STEM) it is nowadays possible to directly image single atomic columns at sub-Å resolution. In standard (high angle) annular dark field STEM ((HA)ADF-STEM), however, light elements are usually invisible when imaged together with heavier elements in one image. Here we demonstrate the capability of the recently introduced Integrated Differential Phase Contrast STEM (iDPC-STEM) technique to image both light and heavy atoms in a thin sample at sub-Å resolution...

OBJECTIVES: The aim of this study was to test whether texture analysis and machine learning enable the detection of myocardial infarction (MI) on non-contrast-enhanced low radiation dose cardiac computed tomography (CCT) images. MATERIALS AND METHODS: In this institutional review board-approved retrospective study, we included non-contrast-enhanced electrocardiography-gated low radiation dose CCT image data (effective dose, 0.5 mSv) acquired for the purpose of calcium scoring of 27 patients with acute MI (9 female patients; mean age, 60 ± 12 years), 30 patients with chronic MI (8 female patients; mean age, 68 ± 13 years), and in 30 subjects (9 female patients; mean age, 44 ± 6 years) without cardiac abnormality, hereafter termed controls...

Unconventional superconductivity in the cuprates coexists with other types of electronic order. However, some of these orders are invisible to most experimental probes because of their symmetry. For example, the possible existence of superfluid stripes is not easily validated with linear optics, because the stripe alignment causes interlayer superconducting tunneling to vanish on average. Here we show that this frustration is removed in the nonlinear optical response. A giant terahertz third harmonic, characteristic of nonlinear Josephson tunneling, is observed in La1...

Glioblastoma are notorious for their highly invasive growth, diffusely infiltrating adjacent brain structures that precludes complete resection, and is a major obstacle for cure. To characterize this "invisible" tumor part, we designed a high resolution multimodal imaging approach assessing in vivo the metabolism of invasively growing glioma xenografts in the mouse brain. Animals were subjected longitudinally to Magnetic Resonance Imaging (MRI) and 1 H spectroscopy (MRS) at ultra high field (14.1 Tesla) that allowed the measurement of 16 metabolic biomarkers to characterize the metabolic profiles...

Three-dimensional (3D) body scanners have the potential to evaluate changes to the human form through different clothing configurations, the use of protective equipment, or the effects of medical interventions. To achieve this, scans of an individual need to be superimposed for each experimental condition. The literature highlights that one of the limiting factors is postural variability. This paper describes a newly developed 'positioning aid' that stabilises the posture during the scanning process and is invisible on scans...

BACKGROUND AND AIMS: Most viruses are detected at early stages of cell infection and induce an innate immune response mediated by production interferons (IFNs). IFNs induce expression of hundreds of IFN-stimulated genes (ISGs). Infection of chimpanzees with hepatitis C virus, but not hepatitis B virus (HBV), induces ISG expression in the liver. HBV might not induce an innate immune response because it is not detected by pattern recognition receptors (the stealth properties of HBV) or because HBV suppresses IFN production or signaling despite detection by pattern recognition receptors...

A material architecture and laser-based microfabrication technique is introduced to produce electrically conductive films (sheet resistance = 2.95 Ω sq-1 ; resistivity = 1.77 × 10-6 Ω m) that are soft, elastic (strain limit >100%), and optically transparent. The films are composed of a grid-like array of visually imperceptible liquid-metal (LM) lines on a clear elastomer. Unlike previous efforts in transparent LM circuitry, the current approach enables fully imperceptible electronics that have not only high optical transmittance (>85% at 550 nm) but are also invisible under typical lighting conditions and reading distances...

We discuss invisibility cloaking of metal grid electrodes on Lambertian light emitters by using dielectric free-form surfaces. We show that cloaking can be ideal in geometrical optics for all viewing directions if reflections at the dielectric-air interface are negligible. We also present corresponding white-light proof-of-principle experiments that demonstrate close-to-ideal cloaking for a wide range of viewing angles. Remaining imperfections are analyzed by ray-tracing calculations. The concept can potentially be used to enhance the luminance homogeneity of large-area organic light-emitting diodes...

BACKGROUND: Frequently diagnosed in young adulthood, multiple sclerosis (MS) and several MS-related factors can influence patients' unemployment status and negatively affect work productivity and daily functioning. OBJECTIVE: We examined MS patients' employment status and evaluated clinical features influencing it. Furthermore, we investigated patients' burdens due to visible and invisible MS symptoms through their worsening daily functioning. METHODS: The study included outpatients affected by MS according to the 2010 McDonald criteria...
