Designing tough biopolymer-based hydrogels as structural biomaterials has both scientific and practical significances. We report a facile approach to prepare polysaccharide-based hydrogel films with remarkable mechanical performances and anti-adhesion property. The hydrogel films with thickness of 40-60 μm were prepared by mixing aqueous solutions of κ-carrageenan (κ-CG) and protonated chitosan (CS), evaporating the solvent, and then swelling the casted film in water to achieve the equilibrium state. The obtained κ-CG/CS gel films with water content of 48-88 wt% possessed excellent mechanical properties superior to most existing biopolymer-based hydrogels, with breaking stress of 2-6...

The trichoscopic features of frontal fibrosing alopecia (FFA) have been described in the frontotemporal area, yet there is no data detailing the trichoscopic features of the sideburns, which can be the initial or exclusive area of involvement. In this retrospective cohort study, 236 trichoscopic images of the frontotemporal and sideburn area obtained via dry trichoscopy from patients with biopsy-proven FFA were examined by two independent researchers to determine the trichoscopic features of FFA in the sideburns...

As the life expectancy is increasing, there is a rise in elderly population and consequent increase in the patients with renal disease. There is an inconsistency between clinical and histopathological diagnosis in elderly, and so renal biopsy is important in these patients to decide appropriate clinical management and prognosis. This study outlines the importance of renal biopsy in elderly and describes the clinical and pathologic spectrum of renal diseases in patient ≥60 years. All patients (age ≥60 years) undergoing renal biopsies from January 2011 to December 2014 were included in this retrospective study...

PURPOSE: We used conjoint analysis to assess the relative importance of factors that influence a patient's decision between surgical or nonsurgical management of a nondisplaced scaphoid fracture. Our hypothesis was that out-of-pocket costs will have a greater influence on decision making than the time spent in a cast or brace, degree of soreness, or the risk of treatment failure. METHODS: Two-hundred and fifty participants were recruited using Amazon Mechanical Turk and asked to assume that they had experienced a nondisplaced scaphoid waist fracture...

This work designed an artificial substrate peptide to synthesize peptide-hemin/G-quadruplex (peptide-DNAzyme) conjugates. In addition to enhancing catalytic activity of hemin/G-quadruplex, the peptide could also be induced and cleaved by prostate specific antigen (PSA). It was the first report on peptide-DNAzyme conjugates in application of the peptide biosensor. The polyethyleneimine-reduced graphene oxide@hollow platinum nanotubes (PEI-rGO@PtNTs) nanocomposites were cast on the glassy carbon electrode in order to form the interface of biocompatibility and huge surface area for bioprobes immobilization...

The aim was to explore the effects of non-polar and polar protic solvents composed of dichloromethane (DCM) and ethanol (EtOH) on the properties of felodipine (FLDP) and Soluplus in solutions, casting films and spray dried drug-rich or polymer-rich solid dispersions (SDs). Measurement of intrinsic viscosity and solubility indicated that FLDP and Soluplus were miscible. EtOH-DCM ranging from 20:80 to 50:50 induced the strongest molecular interactions for FLDP-Soluplus-solvents systems. Accordingly, the casting films and spray dried powders of FLDP and Soluplus were prepared using pure EtOH or DCM and their mixtures as solvents...

INTRODUCTION: Repeated attempts of closed reduction of distal radius fractures (DRF) are performed in the emergency department setting to optimize fracture alignment and avoid surgery. The additional manipulation of the fracture may, however, increase dorsal comminution and lead to loss of reduction in the cast. This retrospective cohort study has investigated the effect of second reduction attempt on fracture alignment and comminution. MATERIALS AND METHODS: Six-hundred-eighteen patients with DRF were treated in the medical center in 2007-2010...

Most extra-articular fractures of the proximal phalanges (P1) of the triphalangeal fingers can be treated conservatively with good results. Prerequisites for successful fracture treatment are intact soft tissue without any lesions of the extensor hood and stable initial fracture reduction. The key to functional conservative treatment of P1 fractures is to immobilize the metacarpophalangeal joints in flexion, resulting in equilibrium of flexor and extensor forces across the fracture site, which converts these inherently unstable fractures into relatively stable fractures...

PURPOSE: Custom tissue compensators provide dosimetric advantages for treating superficial or complex anatomy, but currently available fabrication technology is expensive or impractical for most clinical operations and yields compensators that are difficult for patients to tolerate. We aimed to develop an inexpensive, clinically feasible workflow for generating patient-specific, soft, custom silicone boluses (SCSBs) for head-and-neck (HN) radiation therapy. METHODS AND MATERIALS: We developed a method using 3-dimensional printed parts for generating SCSBs for the treatment of HN cancers...

In natural tissues, the nutrition of cells and removal of waste products is facilitated by a dense capillary network which is generated during development. This perfusion system is also indispensable for tissue formation in vitro. Nutrition depending solely on diffusion is not sufficient to generate tissues of clinically relevant dimensions, which is a core aim in tissue engineering research. In this study, the establishment of a vascular network was investigated in a self-assembling approach employing endothelial and mural cells...

Herein, solvent-treated bandgap-tunable covalent organic nanosheets (CONs) were prepared via the Stille cross-coupling reaction. These materials are considered useful as interlayers in photovoltaic devices upon the alignment of energy levels between other components. Among various types of solar cells, according to the organic-interlayer study, inverted planar perovskite solar cells (PSCs) are mostly demanded to effectively transport and collect charge carriers due to their high performance. At first, the C-V analysis proved the energy levels of the frontier orbitals for CON-10 and CON-16 nanosheets; this verified the suitability of these nanosheets as hole transport layers (HTLs) with the PEDOT:PSS upon casting both films from DMSO...

To address the phenomenon of vaccine hesitancy and rejection, researchers increasingly recognise the need to engage with the social context of parents' decision-making. This study examines how vaccine rejecting parents socially construct the vaccinating mainstream in opposition to themselves. We analyse qualitative data from interviews with parents in Adelaide, South Australia. Applying insights from Social Identity Theory (SIT), we show how these parents bolster their own sense of identity and self-belief by employing a discourse that casts vaccinators as an Unhealthy Other...

The effect of Zn on pore characteristics in lotus-type porous Cu alloy was investigated. The lotustype porous Cu-Zn alloys were fabricated with Zn content from 0.01 to 0.1 at% by the centrifugal casting method. The results demonstrated that the porosity was rarely affected by Zn content. However, the average pore diameter and pore number density of the lotus type porous Cu-Zn alloys were significantly affected by the Zn content. The average pore diameter decreased as the Zn content increased up to 0.01 at%, and then increased as the Zn content increased up to 0...

The microstructure of the as-cast Mg-5Al-3Ca-2Nd-xDy alloys consists of α-Mg matrix, (Mg, Al)2Ca eutectic phase, Al-Nd and Al-Dy intermetallic compounds. α-Mg matrix morphology was changed from dendritic to equiaxed with the increase Dy addition. And grain size was remarkably refined. As Dy content was increased, yield strength was improved due to the refined grains and the homogeneous distribution of Al-Dy phase.
