Background A surgical report is the surgeon's postoperative documentation of the procedure undertaken. The purpose of this study was to evaluate the completeness and accuracy of data extracted from surgical reports, using the example of Dupuytren's disease. Material and Methods Between 1999 and 2007, surgical data were retrospectively collected from all primary Dupuytren's disease procedures performed at an academic department for plastic and reconstructive surgery and analysed for completeness. A surgical report was assessed as complete if data on indication, affected side and finger(s), tourniquet, type of incision and surgical procedure were stated...

An efficient and intelligent nano-carrier that combines cell imaging with near infrared (NIR) light and redox dual-responsive drug delivery was successfully prepared. The hollow mesoporous carbon (HMC) nanoparticles with high photothermal conversion ability were developed to increase the drug loading efficiency and realize chemotherapy and photothermal synergetic therapy. The photo-stable and luminescent carbon dots (CDs) were prepared from branched polyethyleneimine (PEI) by hydrothermal reaction. The PEI CDs (CDPEI) were grafted on the openings of HMC as the "gatekeepers" via disulfide units (HMC-SS-CDPEI) to prevent the premature release of doxorubicin (DOX)...

The formation of composites of reduced graphene oxide (rGO) and magnetic nanoparticles (MP) has flourished in recent years as they combine the advantages of both nanomaterials. Most of these composite materials are prepared by in situ formation of MP onto rGO or by the post-adsorption onto rGO. We report here on a simple and highly controlled method for the fabrication of different magnetic 3D rGO-loaded hydrogels. Cellulose bound magnetic nanoparticles (MP@cellulose) were synthesized by chemical co-precipitation and loaded together with rGO into poly(ethylene glycol) dimethacrylate based hydrogels during their fabrication using photo-polymerization...

Optical printing holds great potential to enable the use of the vast variety of colloidal nanoparticles (NPs) in nano- and micro- devices and circuits. By means of optical forces, it enables the direct assembly of NPs, one by one, onto specific positions of solid surfaces with great flexibility of pattern design and no need of previous surface patterning. However, for unclear causes it was not possible to print NPs closer to each other than 300 nm. Here, we show that the repulsion restricting the optical printing of close by NPs arises from light absorption by the printed NPs and consequent local heating...

INTRODUCTION: The philtral column has an important aesthetic significance and is especially important in patients with cleft lip. If the integrity of the philtrum cannot be preserved in patients of unilateral clefts, these patients will have profound abnormalities in their facial musculature. The purpose of this study was to analyze the effects of dermal grafting on the philtral column in patients with a unilateral alveolar cleft. METHODS: The authors retrospectively studied dermal grafts performed in Konkuk University Medical Center between January 2009 and January 2015...

Representative tertiary amines were linked to the 8-cyano-7-hydroxyquinolinyl (CyHQ) photoremovable protecting group (PPG) to create photoactivatable forms suitable for use in studying cell physiology. The photoactivation of tamoxifen and 4-hydroxytamoxifen, which can be used to activate Cre recombinase and CRISPR-Cas9 gene editing, demonstrated that highly efficient release of bioactive molecules could be achieved through 1- and 2-photon excitation (1PE and 2PE). CyHQ-protected anilines underwent a photo-aza-Claisen rearrangement instead of releasing amines...

Magnetic visible-light-driven photocatalyst, porous C/ZnFe2O4 (denoted as C/ZFO-CE) was fabricated via a CO2-mediated ethanol route. CO2-mediated ethanol route largely mitigated the solvent strength and facilitated the homogenous deposition of ZnFe2O4 (ZFO) through the coordination of metallic cation with CO3(2-) and HCO3(-) anions, which were hydrolyzed from CO2 and H2O, thereby avoiding additional precipitant. Moreover, the HCO3(-), CO3(2-) and NO3(-) in the system acted as templates for the formation of porous C avoiding the additional organic mesoporous templates, thus reducing the synthesis cost...

We report a large magnetically tuned lateral photovoltaic effect (LPE) observed in nanoscale Co-SiO2-Si structures. This tunable effect strongly depends on the location of two electrodes. The change ratio of lateral photovoltage (LPV) can reach up to a considerable value of 94.15% under external magnetic field of 1.77 Teslas. This phenomenon is mainly ascribed to the asymmetric Lorentz force acting on the photo-current in the region of edge area of the nanostructure. It adds a new functionality to the traditional LPE-based devices, and provides a potential prospect for the development of multifunctional high-sensitive photoelectric devices or sensors...

The directional light-induced mass migration phenomenon arising in the photo-responsive azobenzene-containing materials has become an increasingly used approach for the fabrication of controlled tridimensional superficial textures. In the present work we demonstrate the tailoring of the superficial wettability of an azopolymer by means of the light-driven reconfiguration of an array of imprinted micro-pillars. Few simple illumination parameters are controlled to induce non-trivial wetting effects. Wetting anisotropy with controlled directionality, uni-directional spreading and even polarization-intensity driven two-dimensional paths for wetting anisotropy are obtained starting from a single pristine pillar geometry...

Over the past few years the organic/Inorganic hybrid perovskite systems have emerged as a promising class of materials for photo-voltaic and electroluminescent thin film device applications, in view of their unique set of tunable optoelectronic properties. Importantly, these materials can be easily solution-processed at low temperatures and as such are amenable to facile molecular engineering. Thus, a variety of low dimensional forms and quantum structures of these materials can be obtained through strategic synthetic manipulations via small molecule incorporation or molecular ion doping...

As faces become familiar, we come to rely more on their internal features for recognition and matching tasks. Here, we assess whether this same pattern is also observed for a card sorting task. Participants sorted photos showing either the full face, only the internal features, or only the external features into multiple piles, one pile per identity. In Experiments 1 and 2, we showed the standard advantage for familiar faces-sorting was more accurate and showed very few errors in comparison with unfamiliar faces...

In this study, we propose a new polymer substrate that is able to covalently couple intended proteins and reduce nonspecific protein fouling. Poly[2-methacryloyloxyethyl phosphorylcholine (MPC)-ran-N-methacryloyl-(L)-tyrosinemethylester (MAT)] [P(MPC/MAT)] was synthesized by free-radical polymerization. The photooxidation of the MAT unit in the copolymer was observed under ultraviolet (UV) light at 254 nm. P(MPC/MAT) was spin-coated on silicon (Si) and gold substrates. Without UV irradiation of the polymer-coated surface, P(MPC/MAT) physisorbed on the substrates, and the thickness of the polymer layer was less than 10 nm, regardless of the polymer concentration in the coating solution...

Nowadays, silver nanoparticles (AgNP) have been widely used and there are raising concerns about their potential adverse effects on organism. As for the exact toxicity mechanism of AgNP, opinions still vary and whether the released silver ions (Ag(+)) or AgNP themselves are responsible for the toxicity remains debatable. In the present study, we have designed two exposure systems where Ag(+) and AgNP coexisted but differed in quantification by using photo-reduced method with cysteine enantiomers, and their toxicities to freshwater microalgae Scenedesmus obliquus and model plant Arabidopsis thaliana were determined...

REVIEW
Bjorn-Patrick Mohl, Polly Roy
Fluorescent tags constitute an invaluable tool in facilitating a deeper understanding of the mechanistic processes governing virus-host interactions. However, when selecting a fluorescent tag for in vivo imaging of cells, a number of parameters and aspects must be considered. These include whether the tag may affect and interfere with protein conformation or localization, cell toxicity, spectral overlap, photo-stability and background. Cumulatively, these constitute challenges to be overcome. Bluetongue virus (BTV), a member of the Orbivirus genus in the Reoviridae family, is a non-enveloped virus that is comprised of two architecturally complex capsids...

We report a novel technique to fabricate bismuth stannate/silver@silver chloride (Bi2Sn2O7/Ag@AgCl) films on conventional glass substrates. The film exhibited a remarkable self-cleaning capability against organic dyes under visible light. Porous Bi2Sn2O7 (BSO) film was first sintered on a glass substrate, followed by implantation of AgCl in it and photo-induction to produce Ag@AgCl. The degradation of organic dyes and photoelectrochemical studies indicate that, compared with BSO film, Bi2Sn2O7/Ag@AgCl film had a much improved photocatalytic ability, probably due to the enhanced electron transfer efficiency and synergistic effect of visible light absorption of the two semiconductors...

Folliculogenesis is a cycle that produces the majority of oocyte. Any disruption to this cycle leads to ovulation diseases, like polycystic ovarian syndrome (PCOS). Treatments include drugs and surgery; lasers have also been used complementarily. Meanwhile, still there is no definite treatment for PCOS. This study investigated the photo-bio stimulation effect of near-infrared and red low-level laser on producing follicles and compared the result with result of using common drug, clomiphene. Therefore, the aim of this study was to propose the use of lasers autonomously treatment...

Photoelectrochemical (PEC) cells have attracted much attention as a viable route for storing solar energy and producing value-added chemicals and fuels. However, the competition between light absorption and electrocatalysis at a restrained cocatalyst area on conventional planar-type photoelectrodes could limit their conversion efficiency. Here, we demonstrate a new monolithic photoelectrode architecture that eliminate the optical-electrochemical coupling by forming locally nanostructured cocatalysts on a photoelectrode...

In the cool apple-producing areas of northern China, air temperature during early spring changes in a rapid and dramatic manner, which affects the growth and development of apple trees at the early stage of the growing season. Previous studies have shown that the treatment of calcium can increase the cold tolerance of Malus baccata Borkh., a widely-used rootstock apple tree in northern China. To better understand the physiological function of calcium in the response of M. baccata to temperature stress, we analyzed the effect of calcium treatment (2% CaCl₂) on M...
