The performance of a photoelectrochemical (PEC) system is highly dependent on the charge separation, transport and transfer characteristics at the photoelectrode|electrolyte interface. Of the factors that influence the charge behaviors, the crystalline facets of the semiconductor in contact with the electrolyte play an important role but has been poorly studied previously. Here, we present a study aimed at understanding how the different facets of hematite affect the charge separation and transfer behaviors in a solar water oxidation reaction...

We present a unique case of a 62-year-old patient with bilateral osteonecrosis of the femoral heads secondary to corticosteroid use. She presented with an occult right femoral neck fracture and was treated with percutaneous pinning of the right femoral neck and a left-sided percutaneous drilling. Despite apparent appropriate technique, the patient sustained a left sub-trochanteric hip fracture while shifting in bed in the postoperative care unit and was taken back for cephalo-medullary nail fixation. Femoral head osteonecrosis may be an under-reported risk factor for development of pathological neck fractures...

There have been many innovations in the field of ACL-reconstruction over the years, including the FlipCutter® and TightRope® system (both from Arthrex Inc.). The FlipCutter® is a combined guide pin and reamer that allows minimally invasive socket-creation from the inside out, especially in difficult-to-reach areas. The TightRope® is a further development of the well-known Endobutton™ (Smith & Nephew plc) that consists of a four-point knotless locking system. Its main advantage is its adjustability, which makes it possible to fill the entire bone socket with the graft without any empty space...

Background: Nasal fracture and orbital blowout fracture often occur concurrently in cases of midface blunt trauma. Generally, these multiple fractures treatment is surgery, and typically, the nasal bone and orbit are operated on separately. However, we have found that utilizing a transconjunctival approach in patients with concurrent nasal bone fracture and orbital blowout fracture is a useful method. Methods: The participants in the present study included 33 patients who visited the Plastic Surgery outpatient department between March 2014 and March 2017 and underwent surgery for nasal fracture and orbital blowout fracture...

In Arabidopsis thaliana, the endosomal localised Na+/H+ antiporters NHX5 and NHX6 regulate ion and pH homeostasis and are important for plant growth and development. However, the mechanism of how these endosomal NHXs function in plant development is not well understood. Auxin modulates plant growth and development through the formation of concentration gradients in plant tissue to control cell division and expansion. Here, we identified a role for NHX5 and NHX6 in the establishment and maintenance of auxin gradients in embryo and root tissues...

INTRODUCTION: Pharmacist-patient communication during medication counselling has been successfully investigated using Communication Accommodation Theory (CAT). Communication researchers in other healthcare professions have utilised Discursis software as an adjunct to their manual qualitative analysis processes. Discursis provides a visual, chronological representation of communication exchanges and identifies patterns of interactant engagement. AIM: The aim of this study was to describe how Discursis software was used to enhance previously conducted qualitative analysis of pharmacist-patient interactions (by visualising pharmacist-patient speech patterns, episodes of engagement, and identifying CAT strategies employed by pharmacists within these episodes)...

Capillary flow and drying of polymer solutions in open microchannels are explored over timescales spanning seven orders of magnitude, from capillary filling (10-3 -10 s) to the formation of a dry thin film (a 'capillary coating'; 102 -103 s). During capillary filling, drying-induced changes (increased solids content and viscosity) generate micro-scale pinning events that impede contact line motion. Three unique types of pinning are identified and characterized, each defined by the specific location(s) along the contact line at which pinning is induced...

The weak photoluminescence of silver nanoclusters suppresses their broad applications as luminescent nanomaterials. Recent experiments however showed that Au-doping can significantly enhance the photoluminescence intensity of Ag_29 nanoclusters, whereas molecular and physical origins of this effect remain unknown. Therefore we have computationally explored geometric and electronic structures of Ag_29 and its Au-doped Ag_29-xAu_x (x=1-5) nanoclusters in the S_0 and S_1 states. We found that (1) relativistic effects mainly originating from the Au atoms play an important role in enhancing the fluorescence intensity, especially for highly doped Ag_26Au_3, Ag_25Au_4, and Ag_24Au_5; (2) heteronuclear Au-Ag bonds can increase stabilities and regulate fluorescence intensities of isomers of these Au-doped nanoclusters...

In this work, PC61BM:SnO2 electron transport layers (ETLs) were applied in inverted CH3NH3PbI3 perovskite solar cells and a high power conversion efficiency of 19.7% could be obtained. It increased by 49.0% in comparison with the device based on PC61BM-only ETL (13.2%). SnO2 nanocrystals with excellent dispersibility were employed here to fill the pin-holes and cover the valleys of PC61BM layer, forming smooth and compact PC61BM:SnO2 layers. Simultaneously, the electron traps caused by deep-level native defects of SnO2 were reduced by PC61BM proved by the space charge limited current analysis...

Analysis of the transcriptome of the developing wheat grain has associated expression of genes with traits involving production (e.g. yield) and quality (e.g. bread quality). Photosynthesis in the grain may be important in retaining carbon that would be lost in respiration during grain filling and may contribute to yield in the late stages of seed formation under warm and dry environments. A small number of genes have been identified as having been selected by humans to optimize the performance of wheat for foods such as bread...

REVIEW
Tse-Ming Chou, Shih-Pin Chen
PURPOSE OF REVIEW: Chronic migraine (CM) is a recalcitrant subtype of migraine which causes high degrees of disability, poor treatment responses, and frequent recurrences in sufferers. However, the pathophysiological mechanisms underlying the development and chronification of migraine attacks remain incompletely understood. A validated animal model could help to decipher the pathogenic mechanism of the disease, facilitating the development of possible therapeutic strategies for CM. In this review, we aimed to summarize current animal models of CM and discuss the validity of these models...

Actinomycetes are main producers of antibiotics and targeted screening could improve the efficiency of discovering new drugs. This study describes, for the first time, the isolation of endophytic actinomycetes from the macrofungus Ganoderma applanatum. To increase the efficiency of screening, novel actinomycin D (Act D) molecularly-imprinted polymers were adsorbed to the surface of Fe3 O4 @SiO2 magnetic microspheres (MMIPs) and using in the isolation. A monolithic column prepared with magnetic molecularly imprinted polymers was employed to adsorb actinomycin D and its analogues for selective analysis and identification via MS/MS spectroscopy...

Triple-negative breast cancer (TNBC) is a highly metastatic subtype of breast cancer that has limited therapeutic options. Thus, developing novel treatments for metastatic TNBC is an urgent need. Here, we show that nanoparticle-mediated delivery of transforming growth factor-β1-activated kinase-1 (TAK1) inhibitor 5Z-7-Oxozeaenol can inhibit TNBC lung metastasis in most animals tested. P38 is a central signal downstream of TAK1 in TNBC cells in TAK1-mediated response to multiple cytokines. Following co-culturing with macrophages or fibroblasts, TNBC cells express interleukin-1 (IL1) or tumor necrosis factor-α (TNFα), respectively...

BACKGROUND: It has been hypothesized that pre-capillary pulmonary hypertension (PH) may trigger sleep disordered breathing (SDB). In patients with chronic thromboembolic PH (CTEPH), pulmonary endarterectomy (PEA) is potentially effective to improve PH. We assessed the pre- and post-operative prevalence of SDB in CTEPH patients submitted to PEA and the relationship between SDB and clinical, pulmonary and hemodynamic factors. METHODS: Unattended cardiorespiratory recording was performed the night before and one month after elective PEA in 50 patients...
