The selection pressure from echolocating bats has driven the development of a diverse range of anti-bat strategies in insects. For instance, several studies have proposed that the wings of some moths absorb a large portion of the sound energy contained in a bat's ultrasonic cry; as a result, the bat receives a dampened echo, and the moth becomes invisible to the bat. To test the hypothesis that greater exposure to bat predation drives the development of higher ultrasound absorbance, we used a small reverberation chamber to measure the ultrasound absorbance of the wings of nocturnal (Bombycoidea: Saturniidae) and diurnal moths (Chalcosiinae: Zygaenoidea: Zygaenidae)...

Aging Studies and Postcolonial Studies belong together in a rather fundamental way, given that they share profound theoretical roots and far-reaching critical perspectives. These derive not only from the more recent poststructuralist discourse on others but also, further back, from the existentialist discourse on others - particularly in issues relating to "The Look" as elaborated by Jean-Paul Sartre in his major philosophical treatise Being and Nothingness and in his reflections on racism, colonialism and humanism...

We are likely moving rapidly toward a post-antibiotic era, as a result of escalating antimicrobial resistance, rapidly declining antibiotic production and profligate overuse. Hitherto research has almost exclusively focused on doctors' prescribing, with nurses' roles in antibiotic use remaining virtually invisible. Drawing on interviews with 30 nurses, we focus on nurses as brokers of doctors' antibiotic decisions, nursing capacity to challenge doctors' decisions, and, "back stage" strategies for circumnavigating organizational constraints...

High quantum yields (QY) and stable performances are prerequisites for implementing carbon dots in practical applications. In this study, we demonstrate that nitrogen-doped carbon dots (N-CDs), which were prepared via the hydrothermal treatment of citric acid (CA) and tris(hydroxymethyl)methyl aminomethane (Tris), have a high QY of 75%, together with excellent thermal and photo stability. These N-CDs deliver an excellent thermal stability performance over the temperature range of 25 °C to 95 °C, and even at a heating temperature of 90 °C for 360 min...

Increasingly, health communication scholars are attending to how hospital built environments shape communication, patient care processes, and patient outcomes. This multimethod study was conducted on two floors of a newly designed urban hospital. Nine focus groups interviews were conducted with 35 health care professionals from 10 provider groups. Seven of the groups were homogeneous by profession or level: nursing (three groups), nurse managers (two groups), and one group each of nurse care technicians ("techs") and physicians...

The aim of the present study was to examine the value of window technique in qualitative diagnosis of the ground glass opacities (GGO) in patients with non-small cell pulmonary cancer. A total of 124 clinically suspected pulmonary cancer patients were analyzed retrospectively. The lesions were affirmed by puncture biopsy, and were GGO on pulmonary window while were invisible on mediastinal window. Sixty-four multi-detector spiral computed tomography with the window width and window level of 1,500 Hounsfield units (HU) and -450 HU on pulmonary window, while the window width and window level of 400 and 40 HU on mediastinal window, was used in the study...

BACKGROUND: Nowadays, small peripheral pulmonary lesions (PPLs) are frequently detected and the prognosis of lung cancer depends on the early diagnosis. Because of the high fee and requiring specialized training, many advanced techniques are not available in many developing countries and rural districts. METHODS: Three sets of opaque soft copper wires visible under the fluoroscopy (Flu) in the Flu-flexible bronchoscopy (FB) group (n = 24), which determined the three planes of the lesion, were respectively placed firmly on the surface of the chest wall with adhesive tape on the chest wall...

BACKGROUND: Transfusion-transmitted malaria due to asymptomatic Plasmodium infections is a challenge for blood banks. There is a lack of data on the prevalence of asymptomatic infected blood donors and the incidence of transfusion-transmitted malaria in low endemicity areas worldwide. We estimated the frequency of blood donors harbouring Plasmodium in an area in which asymptomatic infections have been reported. MATERIAL AND METHODS: To estimate the frequency of blood donors harbouring Plasmodium we used microscopy and molecular tools...

It has been proposed that humans possess an automatic system to represent mental states ('implicit mentalizing'). The existence of an implicit mentalizing system has generated considerable debate however, centered on the ability of various experimental paradigms to demonstrate unambiguously such mentalizing. Evidence for implicit mentalizing has previously been provided by the 'dot perspective task,' where participants are slower to verify the number of dots they can see when an avatar can see a different number of dots...

Contrast enhancement of glioblastomas (GBM) is caused by the decrease in relaxation time, T1. Here, we demonstrate that the quantitative measurement of T1 (qT1) discovers a subtle enhancement in GBM patients that is invisible in standard MRI. We assessed the volume change of this "cloudy" enhancement during radio-chemotherapy and its impact on patients' progression-free survival (PFS). We enrolled 18 GBM patients in this observational, prospective cohort study and measured 3T-MRI pre- and post contrast agent with standard T1-weighted (T1w) and with sequences to quantify T1 before radiation, and at 6-week intervals during radio-chemotherapy...

In 2012, 20% of high school students were bullied in the United States. Bullying is more prevalent among minority populations. Arab American adolescents receive little research attention and are described as the invisible population. This descriptive qualitative study was conducted with 10 Arab American adolescent bullying victims to describe their bullying experiences and related stress. In addition to being bullied because of health problems or social disadvantages, Arab American adolescents reported that they were bullied because of their ethnic/racial background and religious affiliation...

Although recent changes in health care delivery have improved routine and gender-affirming care for transgender people, common approaches to care are still often based on a binary (i.e., male/female) gender framework that can make patients with gender-nonconforming (GNC) identities and expressions feel marginalized. Binary representation perpetuates invisibility, discrimination, and victimization-and subsequent poorer health-among GNC patients. In response, clinicians and health care systems should extend their efforts to provide gender-affirming and responsible care to GNC people...

Animals inhabiting the open ocean often conceal themselves by being highly transparent, but this transparency is compromised by light that is scattered and reflected from the body surface. New research shows that some midwater crustaceans use antireflection coatings to enhance their invisibility.

BACKGROUND AND AIMS: The effectiveness of the treatments carried out in the Intensive Care Unit (ICU) is guaranteed by a socio-technical ensemble where material resources, scientific knowledge, technological artefacts, social norms, spatial dispositions, and professional practices coexist and constantly interact. This paper intends to penetrate such an ensemble for analysing the moral order produced and maintained in everyday medical practice. METHOD: The results of a case study, carried out in the ICU of a hospital in the north of Italy between 2006 and 2007 are reported...

Progress in altering the current obesity epidemic among children and adolescents remains elusive. Evidence continues to underscore the challenges of altering weight status as children age. Further, weight loss interventions among children and adults alike tend to demonstrate efficacy in the short-term, however individuals tend to slowly revert back to their original weight status over time. New understanding of obesity's early origins suggests the need to rethink current approaches, particularly within healthcare...

Nanoparticles with long blood circulation time are a prerequisite for targeted drug delivery. To make the nanoparticles invisible for phagocytizing cells, functional moieties on the particle surface are believed to be necessary to attract specific so-called 'stealth' proteins forming a protein 'corona'. Currently, covalent attachment of those moieties represents the only way to achieve that attraction. However, that approach requires a high synthetic effort and is difficult to control. Therefore, we present the coating of model nanoparticles with biodegradable polymeric surfactants as an alternative method...
