The addition of Re to Ni on TiO2 yields efficient catalysts for the hydrogenation of acids and esters to alcohols under mild conditions. Rhenium promotes the formation of atomically dispersed and sub-nanometre-sized bimetallic species interacting strongly with the oxide support.

CD177 is a GPI-anchored protein expressed by a variable proportion of human neutrophils that mediates surface expression of the anti-neutrophil cytoplasmic antibody (ANCA) antigen proteinase 3. CD177 associates with β2 integrins and recognizes PECAM-1, suggesting a role in neutrophil migration. However, CD177(pos) neutrophils exhibit no clear migratory advantage in vivo, despite interruption of transendothelial migration by in vitro CD177 ligation. We sought to understand this paradox. Using a PECAM-1-independent transwell system, we found that CD177(pos) and CD177(neg) neutrophils migrated comparably...

Although increasingly frequent, little is known about the clinical presentation, radiological signs, and outcome of Candida vertebral osteomyelitis (CVO).We performed a nationwide retrospective study of laboratory-confirmed cases of CVO over a 10 year-period in France with a prolonged follow-up. We describe demographic, clinical, biological, and radiological characteristics of patients with CVO, patients' management, and long-term outcome and determine factors associated with a poor outcome.In total, 28 patients with laboratory-confirmed CVO were included...

Our objective was to report the orthodontic and surgical retreatment of a patient who had undergone a prolonged orthodontic treatment with extractions, but who had unsatisfactory results and persistent side effects. The man, aged 25 years 3 months, sought treatment with major complaints of facial and smile asymmetries. The clinical examination showed a mandibular deviation to the right and a maxillary occlusal cant. A Class II Division 1 subdivision right was observed. Radiographic examination showed extensive root resorptions in the maxillary second premolars and absence of the 4 first premolars...

Background and study aims Endoscopic sphincterotomy plus large-balloon dilation (ES-LBD) has been reported as an alternative to endoscopic sphincterotomy for the removal of bile duct stones. This multicenter study compared complete endoscopic sphincterotomy with vs. without large-balloon dilation for the removal of large bile duct stones. This is the first randomized multicenter study to evaluate these procedures in patients with exclusively large common bile duct (CBD) stones. Methods Between 2010 and 2015, 150 patients with one or more common bile duct stones ≥ 13 mm were randomized to two groups: 73 without balloon dilation (conventional group), 77 with balloon dilation (ES-LBD group)...

The development of an efficient, high yielding six-step convergent synthesis of the semisynthetic alkaloid (-)-perhydrohistrionicotoxin is described. The key transformations include the cross metathesis of a Brønsted-acid masked primary homoallylic amine with a vinyl cyclohexenone and a regioselective palladium catalyzed hydrogenation. This sequence generated the advanced Winterfeldt spirocyclic precursor in 47% overall yield, with a longest linear sequence of five steps.

We report here the whole-genome sequences of 14 strains of Bradyrhizobium canariense, isolated from root nodules of Lupinus microanthus and Lupinus angustifolius, and 1 strain of Bradyrhizobium japonicum isolated from root nodules from Lupinus angustifolius in Algeria. These sequences add to the known diversity of this agronomically important genus.

Paediatric perfusion during pre-hospital care is a major issue in the event of life-threatening emergencies. Access, often restricted, to backup specialising in paediatrics, implies the existence of practices on protocols for the adult mobile emergency and intensive care service (Smur) in partnership with paediatricians. Paediatric perfusion practices were assessed in these teams. The results show the presence of a paediatric protocol in the adult Smur teams is not very common. Nursing practices seem to be evolving towards the recommendations, thanks to technological advances such as the use of the intraosseous device...

The influence of infrared laser pulses on intracellular Ca(2+) signaling was investigated in neural cell lines with fluorescent live cell imaging. The probe Fluo-4 was used to measure Ca(2+) in HT22 mouse hippocampal neurons and non-electrically excitable U87 human glioblastoma cells exposed to 50-500 ms infrared pulses at 1470 nm. Fluorescence recordings of Fluo-4 demonstrated that infrared stimulation induced an instantaneous intracellular Ca(2+) transient with similar dose-response characteristics in hippocampal neurons and glioblastoma cells (half-maximal effective energy density EC50 of around 58 J...

BACKGROUND: A survey was utilized to study the coding practices of surgeons performing craniofacial procedures, in order to determine whether coding for these procedures might be standardized or expanded. METHODS: An online survey was designed with 6 sample cases to cover a variety of procedures encountered in the field of craniofacial surgery which was sent to members of 3 professional organizations centered around the practice of craniofacial/maxillofacial surgery...

REVIEW

The initial assessment and care determine the quality of the secondary surgical treatment of complex hand wounds. The caregiver providing this initial care plays a critical role. The analysis of the management of these traumas in exceptional situations enables the key stages of the initial treatment to be identified: bleeding control, infection prevention and an accurate assessment of the injury. These measures thereby help to optimise the patient's transfer towards a specialised unit.

INTRODUCTION: The selection of patients with metastatic clear cell renal cell carcinoma (ccRCC) who may benefit from targeted tyrosine kinase inhibitors has been a challenge, even more so now with the advent of new therapies. Hilar fat infiltration (HFI) is a validated prognostic factor in nonmetastatic ccRCC (TNM 2009 staging system) but has never been studied in metastatic patients. We aimed to assess its phenotype and prognostic effect in patients with metastatic ccRCC treated with first-line sunitinib...

Chronic pain requires affected individuals to self-manage their health. This study compared barriers and facilitators of self-management in two groups of people with chronic pain: those with and without neuropathic characteristics. A cross-sectional survey study of community-dwelling Canadians was conducted. The sample (n = 710) included randomly selected participants who reported chronic pain. The Self-Report Leeds Assessment of Neuropathic Symptoms and Signs was used to screen for neuropathic characteristics...

Uncoupling protein 2 (UCP2), whose physiological role is to decrease mitochondrial membrane potential and reactive oxygen species (ROS) production, is often overexpressed in human cancers. UCP2 upregulation has recently been proposed as a novel survival mechanism for cancer cells. However, until now, how exactly UCP2 promotes tumorigenesis remains inconclusive. Based on a widely used skin cell transformation model, our data demonstrated that UCP2 differentially regulated ROS. UCP2 upregulation decreased superoxide whereas it increased hydrogen peroxide production with concomitant increase in the expression and activity of manganese superoxide dismutase (MnSOD), the primary mitochondrial antioxidant enzyme...

Four metagenomes of epiphytic and endophytic microbiota of lavender and rose flowers are also reported.

BACKGROUND: Self-drilling osteosynthesis screws (SDS) have a potential higher primary stability together with clinical advantages such as less time effort compared to self-tapping screws (STS). The aims of the study were to compare the primary stability of SDS and STS ex vivo and to analyze of the time-saving effect in vivo. MATERIALS AND METHODS: Ex vivo, both screws were placed in porcine bone. Torque was measured for insertion and removal. Four specimens were kept in bone for histologic bone-to-implant-contact examination...
