The appearance of wings in insects, early in their evolution [1], has been one of the more critical innovations contributing to their extraordinary diversity. Despite the conspicuousness and importance of wings, the origin of these structures has been difficult to resolve and represented one of the "abominable mysteries" in evolutionary biology [2]. More than a century of debate has boiled the matter down to two competing alternatives-one of wings representing an extension of the thoracic notum, the other stating that they are appendicular derivations from the lateral body wall...

Jung Ho Je, Jong-Man Kim, Justyn Jaworski
The fountain pen approach, as a means for transferring materials to substrates, has shown numerous incarnations in recent years for creating 2D micro/nanopatterns and even generating 3D free-form nanostructures using a variety of material "inks". While the idea of filled reservoirs used to deliver material to a substrate via a capillary remains unchanged since antiquity, the advent of precise micromanipulation systems and functional material "inks" allows the extension of this mechanism to more high-tech applications...

PURPOSE: Total Variation (TV) based iterative reconstruction (IR) methods enable accurate CT image reconstruction from low-dose measurements with sparse projection acquisition, due to the sparsifiable feature of most CT images using gradient operator. However, conventional solutions require large amount of iterations to generate a decent reconstructed image. One major reason is that the expected piecewise constant property is not taken into consideration at the optimization starting point...

PURPOSE: To estimate and remove the scatter contamination in the acquired projection of cone-beam CT (CBCT), to suppress the shading artifacts and improve the image quality without prior information. METHODS: The uncorrected CBCT images containing shading artifacts are reconstructed by applying the standard FDK algorithm on CBCT raw projections. The uncorrected image is then segmented to generate an initial template image. To estimate scatter signal, the differences are calculated by subtracting the simulated projections of the template image from the raw projections...

BACKGROUND: Genome-wide association studies (GWAS) have provided insight into cancer genetics. However, molecular mechanisms whereby many susceptibility single nucleotide polymorphisms (SNPs) identified by GWAS promote cancer heritability and risk are unknown. New research strategies to evaluate functionality are needed to systematically study causal genetic variants. METHODS: In this study, we developed an integrative functional genomics method to identify cancer susceptibility SNPs in transcription factor binding sites across the whole genome...

BACKGROUND: For patients with complex care needs, engagement in disease management activities is critical. Chronic illnesses touch almost every person in the United States. The costs are real, personal, and pervasive. In response, patients often seek tools to help them manage their health. Patient portals, personal health records tethered to an electronic health record, show promise as tools that patients value and that can improve health. Although patient portals currently focus on the outpatient experience, the Ohio State University Wexner Medical Center (OSUWMC) has deployed a portal designed specifically for the inpatient experience that is connected to the ambulatory patient portal available after discharge...

INTRODUCTION: Heavy episodic ("binge") drinking among women in Scotland is commonplace; prepregnancy drinking is associated with continued antenatal drinking. Evidence for effectiveness of standardized antenatal alcohol assessment is lacking. Alcohol-exposed pregnancies may be missed. We assessed peri-conceptual and mid-pregnancy consumption using a week-long retrospective diary and standard alcohol questionnaires, and evaluated the agreement between these instruments. MATERIAL AND METHODS: Cross-sectional study in two Scottish health board areas involving 510 women attending mid-pregnancy ultrasound scan clinics...

BACKGROUND: Sex- and gender-based medicine (SGBM) aims to (1) delineate and investigate sex- and gender-based differences in health, disease, and response to treatment and (2) apply that knowledge to clinical care to improve the health of both women and men. However, the integration of SGBM into medical school curricula is often haphazard and poorly defined; schools often do not know the current status of SGBM content in their curricula, even if they are committed to addressing gaps and improving SGBM delivery...

Over the last decade, patient volumes in the emergency department (ED) have grown disproportionately compared to the increase in staffing and resources at the Toronto Western Hospital, an academic tertiary care centre in Toronto, Canada. The resultant congestion has spilled over to the ED waiting room, where medically undifferentiated and potentially unstable patients must wait until a bed becomes available. The aim of this quality improvement project was to decrease the 90th percentile of wait time between triage and bed assignment (time-to-bed) by half, from 120 to 60 minutes, for our highest acuity patients...

BACKGROUND: Today, Brazil is the second country of the world in number of transplants. Nonetheless, waiting lists are getting longer. This lack of organs occurs mostly because of people's reduced knowledge about the donation process. With the aim of changing this scenario, in 2013 and 2014, "Organ Donation Week" events were held at the Federal University of Health Sciences of Porto Alegre. METHODS: During the 2 years, documentaries followed by a cycle of debates with experts in this area were exhibited...

BACKGROUND: Previous research has shown that hearing aid wearers can successfully self-train their instruments' gain-frequency response and compression parameters in everyday situations. Combining hearing aids with a smartphone introduces additional computing power, memory, and a graphical user interface that may enable greater setting personalization. To explore the benefits of self-training with a smartphone-based hearing system, a parameter space was chosen with four possible combinations of microphone mode (omnidirectional and directional) and noise reduction state (active and off)...
