Droplet-guiding superhydrophobic SERS substrates are created by a combinatorial lithographic technique. Photolithography defines the pattern of a micropillar array with a radial density gradient, whereas colloidal lithography features a nanotip array on the top surface of each micropillar. The nanotip array renders the surface superhydrophobic and the pattern of micropillars endows the radial gradient of contact angle, enabling the spontaneous droplet migration toward the center of the pattern. Water droplets containing target molecules are guided to the center and the molecules dissolved in the droplets are concentrated at the surface of the central micropillar during droplet evaporation...

Multimodal features of structural and functional magnetic resonance imaging (MRI) of the human brain can assist in the diagnosis of schizophrenia. We performed a classification study on age, sex, and handedness-matched subjects. The dataset we used is publicly available from the Center for Biomedical Research Excellence (COBRE) and it consists of two groups: patients with schizophrenia and healthy controls. We performed an independent component analysis and calculated global averaged functional connectivity-based features from the resting-state functional MRI data for all the cortical and subcortical anatomical parcellation...

M Abu-Serriah, S Loughran
Circumferential defects of the hypopharynx are a reconstructive challenge. Various local, regional and free flaps have been described with each having advantages and disadvantages in terms of functional outcomes. The fasciocutaneous radial forearm free flap (RFFF) is one of the most common free flaps used for reconstructing circumferential hypopharyngeal defects. The skin paddle is pliable and reasonably matches the native hypopharyngeal wall. It is easy to raise, has predictable vascular anatomy and a long pedicle...

PURPOSE: The purpose of this article is to demonstrate that brachytherapy source tracking can be realized with in vivo dosimetry. This concept could enable real-time treatment monitoring. METHODS: In vivo dosimetry was incorporated in the clinical routine during high-dose-rate prostate brachytherapy at Aarhus University Hospital. The dosimetry was performed with a radioluminescent crystal positioned in a dedicated brachytherapy needle in the prostate. The dose rate was recorded every 50-100 ms during treatment and analyzed retrospectively...

It has long been accepted that differential radial thickening of guard cells plays an important role in the turgor-driven shape changes required for stomatal pore opening to occur [1-4]. This textbook description derives from an original interpretation of structure rather than measurement of mechanical properties. Here we show, using atomic force microscopy, that although mature guard cells display a radial gradient of stiffness, this is not present in immature guard cells, yet young stomata show a normal opening response...

Do all animals sleep? Sleep has been observed in many vertebrates, and there is a growing body of evidence for sleep-like states in arthropods and nematodes [1-5]. Here we show that sleep is also present in Cnidaria [6-8], an earlier-branching metazoan lineage. Cnidaria and Ctenophora are the first metazoan phyla to evolve tissue-level organization and differentiated cell types, such as neurons and muscle [9-15]. In Cnidaria, neurons are organized into a non-centralized radially symmetric nerve net [11, 13, 15-17] that nevertheless shares fundamental properties with the vertebrate nervous system: action potentials, synaptic transmission, neuropeptides, and neurotransmitters [15-20]...

Patient-reported quality of life (QoL) outcomes have the potential to assist clinicians in providing individually tailored treatment decisions. QoL assessments were collected prospectively for 168 consecutive patients treated for oral cancer between 1 January 2010 and 31 December 2014 using the University of Washington Quality of Life Questionnaire. Patients were followed up for 18 months post-treatment. Sub-group analyses were performed using paired t-tests and analysis of variance (ANOVA) to compare the effects of adjunctive chemoradiotherapy, type of bone resection, and methods of soft and hard tissue flap reconstruction...

BACKGROUND: Recently, several meta-analyses of randomized controlled trials (RCTs) have shown that transradial access (TRA) reduces mortality compared to transfemoral access (TFA). However, a critical appraisal of these RCTs suggests that the findings could have resulted from a greater incidence of adverse events in the TFA groups rather than a beneficial effect of TRA. METHODS: Scientific databases and websites were searched for RCTs. Patients were divided into groups based on access type and whether the operator was a radial expert (RE) or non-radial expert (NRE)...

Background/Aims: Although both radial- and convex-arrayed endoscopic ultrasonography (EUS) scopes are widely used for observational EUS examinations, there have been few comparative studies on their power of visualization. The aim of this study was to evaluate the capability of these EUS scopes for observation of the pancreatobiliary junction. Methods: The rate of successful visualization of the pancreatobiliary junction was retrospectively compared between a radial-arrayed and a convex-arrayed echoendoscope, from a prospectively maintained database...

The human neocortex is organized radially into six layers which differ in their myelination and the density and arrangement of neuronal cells. This cortical cyto- and myeloarchitecture plays a central role in the anatomical and functional neuroanatomy but is primarily accessible through invasive histology only. To overcome this limitation, several non-invasive MRI approaches have been, and are being, developed to resolve the anatomical cortical layers. As a result, recent studies on large populations and structure-function relationships at the laminar level became possible...

Silicon (Si) is used in various application fields such as solar cells and electric devices. Functionalization of Si nanostructures is one way to further improve the properties of these devices such as these. This Review summarizes recent results of solar cell and Li-ion battery applications using Si-related nanostructures. In solar cell applications, the light trapping effect is increased and the carrier recombination rate is decreased due to the short carrier collection path achieved by radially constructed p-n junction in Si nanowires, resulting in higher power conversion efficiency...

OBJECTIVE: Research suggests that the presence of instability markers in patients with displaced distal radial fractures is associated with poorer outcome. Our aims were to determine whether the presence of previously defined instability markers could predict the likelihood of successful ED reduction and requirement for a secondary procedure after ED reduction. METHODS: Retrospective cohort study performed by medical record review. Adult ED patients coded as having an isolated wrist fracture and having fracture reduction in ED were eligible for inclusion...

Climate change is expected to increase drought frequency and intensity what will threaten plant growth and survival. In such fluctuating environments, perennial plants respond with hydraulic and biomass adjustments, resulting in either tolerant or avoidant strategies. Plant's response to stress relies on their phenotypic plasticity. Our goal was to explore physiology of young Populus nigra in the context of a time-limited and progressive water deficit in regard with their growth and stress response strategies...

OBJECTIVES: To assess, whether cardiac catheterization via radial access prevents contrast-induced nephropathy. BACKGROUND: Contrast-induced nephropathy (CIN) is a major clinical problem which accounts for more than 10% of acute kidney injury cases in hospitalized patients. Protective measures such as the infusion of isotonic saline solution or acetylcysteine have not consistently been proven to prevent acute kidney injury (AKI). However, there is growing evidence that radial access for coronary angiography and coronary intervention is associated with a lower incidence of AKI compared to femoral access...
