The poor bonding strength between biopolymer and bioceramic has remained an unsolved issue. In this study, graphene oxide (GO) was introduced as an interface phase to improve the interfacial bonding between polyetheretherketone (PEEK) and hydroxyapatite (HAP) for tissue engineering scaffolds. On the one hand, the conjugated structure of GO could form strong π-π stacking interaction with the benzene rings in PEEK. On the other hand, GO with a negatively charge resulting from oxygen functional groups could adsorb the positively charged calcium atoms (C sites) of HAP...

Intelligent vesicles are fabricated at up to 30% solid content via an approach of polymerization-induced self-assembly and reorganization (PISR). Upon irradiation with UV light (365 nm), light-triggered dimerization of the coumarin moieties anchored in the membrane leads to the membrane cross-linking of the vesicles, which endows the vesicles with superior structural stability. Due to the tertiary amine groups in the membrane, the vesicles go through a swelling/deswelling change upon switching the pH values...

Though benign in the majority of cases, sleepwalking sometimes causes injuries due, among other causes, to falls. Such accidents can be life-threatening - a situation that has been termed Elpenor syndrome (in reference to an accident experienced by a character in Homer's epic The Odyssey) - in particular when entailing defenestration. This syndrome has been described in adults and adolescents; we report here a case in a child. OBSERVATION: This 10-year-old girl was admitted at night to our hospital after a 3-m fall at home...

INTRODUCTION: In France, 26 regional pediatric palliative care teams (ERRSPP) were created between 2008 and 2012. We conducted the first prospective French study to describe the main specifications of the initial contact with an ERRSPP and to analyze the responses given. DESIGN AND METHODS: All the requests for interventions on the part of the ERRSPP were collected between September 2013 and September 2014. We prospectively completed a questionnaire on the patient's clinical and demographic data (age, sex, disease), details regarding the request (type of applicant, unit's specialty, request pattern), and the answers provided (interval between diagnosis and request, duration of care by ERRSPP, death, changes compared to the initial request)...

Pelteobagrus vachellii, an important freshwater fish in China, shows predominantly nocturnal behavior. To better understand the growth and molecular mechanisms underlying altered feeding times in this species, we studied the growth and liver transcriptome of P. vachellii with shifted feeding times. In this study, a 9-week growth trial was conducted on male P. vachellii (mean weight±S.E.=1.05±0.36g) with commercial feed. Two triplicate groups of fish were fed either at 0800 (day group, control) or at 2000 (night group) with the same amount of feed...

Rehabilitation for patients with Parkinson's disease (PD) is based on cognitive strategies that exploit attention. Parkinsonians exhibit impairments in divided attention and interference control. Nevertheless, the effectiveness of specific rehabilitation treatments based on attention suggests that other attentional functions are preserved. Data about attention are conflicting in PD, and it is not clear whether rehabilitative treatments that entail attentional strategies affect attention itself. Reaction times (RTs) represent an instrument to explore attention and investigate whether changes in attentional performances parallel rehabilitation induced-gains...

Radiotherapy is widely used in cancer treatment, however the benefits can be limited by radiation-induced damage to neighboring normal tissues. Parthenolide (PTL) exhibits anti-inflammatory and anti-tumor properties and selectively induces radiosensitivity in prostate cancer cell lines, while protecting primary prostate epithelial cell lines from radiation-induced damage. Low doses of radiation have also been shown to protect from subsequent high-dose-radiation-induced apoptosis as well as DNA damage. These properties of PTL and low-dose radiation could be used to improve radiotherapy by killing more tumor cells and less normal cells...
