In optical experiments one-sided reflectionless (ORL) and coherent perfect absorption (CPA) are unusual scattering properties yet fascinating for their fundamental aspects and for their practical interest. Although these two concepts have so far remained separated from each other, we prove that the two phenomena are indeed strictly connected. We show that a CPA-ORL connection exists between pairs of points lying along lines close to each other in the 3D space-parameters of a realistic lossy atomic photonic crystal...

In this paper, we propose a novel graph-based semisupervised learning framework, called joint sparse representation and embedding propagation learning (JSREPL). The idea of JSREPL is to join EPL with sparse representation to perform label propagation. Like most of graph-based semisupervised propagation learning algorithms, JSREPL also constructs weights graph matrix from given data. Different from classical approaches which build weights graph matrix and estimate the labels of unlabeled data in sequence, JSREPL simultaneously builds weights graph matrix and estimates the labels of unlabeled data...

We have tested the original interaction-strength-interpolation (ISI) exchange-correlation functional for main group chemistry. The ISI functional is based on an interpolation between the weak and strong coupling limits and includes exact-exchange as well as the Görling-Levy second-order energy. We have analyzed in detail the basis-set dependence of the ISI functional, its dependence on the ground-state orbitals, and the influence of the size-consistency problem. We show and explain some of the expected limitations of the ISI functional (i...

BACKGROUND: In severe cases of epistaxis, in spite of several procedures described in the literature for its management, surgical treatment has been recognized by most authors as 1 of the most effective, especially when it includes ligation and/or electrocoagulation of the nasal branches of the sphenopalatine artery. The objective of this study is to determine the importance of ethmoid crest resection during sphenopalatine artery surgery, in the management of severe epistaxis. METHODS: We report a double-blinded randomized clinical trial, in which intervention was the ethmoid crest resection during electrocoagulation of the sphenopalatine artery...

BACKGROUND: The EXTREME (Erbitux in First-Line Treatment of Recurrent and Metastatic Head and Neck Squamous Cell Carcinoma) protocol is generally considered the gold standard in palliative first-line treatment. However, there is some disagreement about its effectivity, toxicity, and applicability in daily clinical routine. The purpose of this cross-sectional survey was to describe the palliative treatment offered in German-speaking countries. METHODS: From November 2013 to July 2014, 204 departments of otorhinolaryngology (ORL) in Germany, Austria, and the German-speaking parts of Switzerland were contacted and invited to take part in a web-based survey on the treatment of HNSCC...

OBJECTIVE: To provide recommendations for the comprehensive management of young infants who present with signs or symptoms concerning for laryngomalacia. METHODS: Expert opinion by the members of the International Pediatric Otolaryngology Group (IPOG). RESULTS: Consensus recommendations include initial care and triage recommendations for health care providers who commonly evaluate young infants with noisy breathing. The consensus statement also provides comprehensive care recommendations for otolaryngologists who manage young infants with laryngomalacia including: evaluation and treatment considerations for commonly debated issues in laryngomalacia, initial work-up of infants presenting with inspiratory stridor, treatment recommendations based on disease severity, management of the infant with feeding difficulties, post-surgical treatment management recommendations, and suggestions for acid suppression therapy...

Chikungunya virus (CHIKV) is an emerging mosquito-borne virus belonging to the Togaviridae, which is transmitted to humans by Aedes aegypti and Ae. albopictus. We describe the infection pattern of CHIKV in two New World Ae. aegypti strains, HWE and ORL. Both mosquito strains were susceptible to the virus but showed different infection patterns in midguts and salivary glands. Even though acquisition of a bloodmeal showed moderate levels of apoptosis in midgut tissue, there was no obvious additional CHIKV-induced apoptosis detectable during midgut infection...

OBJECTIVES: Endoscopic resection has become an established surgical option for most juvenile nasopharyngeal angiofibromas (JNA). However, surgical management of JNA with intracranial extension remains challenging. This retrospective multicenter study reviews a series of patients with advanced stage JNA treated via endonasal/endoscopic approach. METHODS: The experience of five academic tertiary or quaternary care ORL-HNS Departments were included. Medical records of all patients operated for JNA staged as Radkowski stage IIIA or IIIB were reviewed...

Emerging biological and translational insights from large sequencing efforts underscore the need for genetically-relevant cell lines to study the relationships between genomic alterations of tumors, and therapeutic dependencies. Here, we report a detailed characterization of a novel panel of clinically annotated oral squamous cell carcinoma (OSCC) cell lines, derived from patients with diverse ethnicity and risk habits. Molecular analysis by RNAseq and copy number alterations (CNA) identified that the cell lines harbour CNA that have been previously reported in OSCC, for example focal amplications in 3q, 7p, 8q, 11q, 20q and deletions in 3p, 5q, 8p, 18q...

Nanostructured Fe-Mn and Fe-Mn-Zn metal scaffolds were generated through a well-controlled selective leaching process in order to fulfill the growing demand for adjustable degradation rates and improved cellular response of resorbable materials. Mouse bone marrow mesenchymal stem cells (D1 ORL UVA) were seeded onto eleven, carefully chosen nanoporous surfaces for 24 h in vitro. Using a combination of fluorescence microscopy, scanning electron microscopy (SEM), and an MTS assay, it was discovered that scaffolds with nanoscale roughened surfaces had increased cell attachment by up to 123% compared to polished smooth Fe-Mn surfaces...

Previous studies have identified potential antidepressant effects of buprenorphine (BPN), a drug with high affinity for mu opioid receptor (MORs) and kappa opioid receptors (KORs) and some affinity at delta opioid receptor (DOR) and opioid receptor-like 1 (ORL-1) receptors. Therefore, these studies examined which opioid receptors were involved in BPN's effects on animal behavior tests sensitive to antidepressant drugs. The acute effects of BPN were tested in the forced swim test (FST) using mice with genetic deletion of individual opioid receptors or after pharmacological blockade of receptors...

The social isolation rearing of young adult rats is a model of psychosocial stress and provides a nonpharmacological tool to study alterations reminiscent of symptoms seen in psychosis. We have previously demonstrated that social isolation in rats leads to increased oxidative stress and to cerebral NOX2 elevations. Here, we investigated early alterations in mRNA expression leading to increased NOX2 in the brain. Rats were exposed to a short period of social isolation (1 week) and real-time polymerase chain reaction (PCR) for mRNA expression of genes involved in blood-brain barrier (BBB) formation and integrity (ORLs, Vof 21 and Vof 16, Leng8, Vnr1, and Trank 1 genes) was performed...

OBJECTIFS: HTA et cancer sont deux affections très fréquentes de par le monde, sources d'une morbi-mortalité importantes. De nombreuses études rapportent une forte association entre ces deux affections. L'HTA semble aug-menter l'incidence et la mortalité pour certains cancers : rein, ORL, colon, rectum, poumon, vessie, mélanome. Certains traitements de l'HTA semblent incriminés pour certains types de cancers. Cependant d'éventuels liens physio-pathologiques entres ces deux affections demeurent encore inconnus...
