#1
Shoubiao Tan, Xi Sun, Wentao Chan, Lei Qu, Ling Shao
In this paper, a novel joint sparse representation method is proposed for robust face recognition. We embed both group sparsity and kernelized locality-sensitive constraints into the framework of sparse representation. The group sparsity constraint is designed to utilize the grouped structure information in the training data. The local similarity between test and training data is measured in the kernel space instead of the Euclidian space. As a result, the embedded nonlinear information can be effectively captured, leading to a more discriminative representation...

BACKGROUND: Learners often utilize online resources to supplement formalized curricula, and to appropriately support learning, these resources should be of high quality. Thus, the objectives of this study are to develop and provide validity evidence supporting an assessment tool designed to assess the quality of educational websites in Otolaryngology- Head & Neck Surgery (ORL-HNS), and identify those that could support effective web-based learning. METHODS: After a literature review, the Modified Education in Otolaryngology Website (MEOW) assessment tool was designed by a panel of experts based on a previously validated website assessment tool...

BACKGROUND: Emergencies are not uncommon in a typical otorhinolaryngological (ORL) clinic. The knowledge of the profile and prevalence of these emergencies will go a long way in helping to equip as well as aid proper and prompt management of these conditions so as to reduce their morbidity and mortality. PATIENTS AND METHODS: A descriptive retrospective 8 years review of all patients that presented to the ENT Surgery Department from January 2004 to December 2012...

AIM: To evaluate the potential role of hyperreflective foci (HF) as a prognostic indicator of visual outcome in patients with macular edema (ME) due to retinal vein occlusion (RVO). METHODS: We retrospectively reviewed 50 eyes of 50 patients with ME due to ischemic central retinal vein occlusion (CRVO), non-ischemic CRVO and branch retinal vein occlusion (BRVO) who were treated with anti-vascular endothelial growth factor (anti-VEGF) at Beijing Tongren Eye Center from January 2013 to July 2016...

PURPOSE: To compare intra-retinal layer thickness measurements between eyes with no or mild diabetic retinopathy (DR) and age-matched controls using Spectralis spectral-domain optical coherence tomography (SD-OCT). METHODS: Cross-sectional observational analysis study. High-resolution macular volume scans (30° * 25°) were obtained for 133 type 2 diabetes mellitus (T2DM) patients with no DR, 42 T2DM patients with mild DR and 115 healthy controls. The mean thickness was measured in all 9 Early Treatment Diabetic Retinopathy Study (ETDRS) sectors for 8 separate layers, inner retinal layer (IRL), outer retinal layer (ORL) and total retina (TR), after automated segmentation...

PURPOSE: Release of the orbicularis retaining ligament (ORL) has been advocated as a technique to address tear trough deformities. This study sought to compare the effectiveness and morbidity of lower blepharoplasty with and without ORL release. METHODS: Retrospective chart review of 53 lower blepharoplasty patients. Twenty-six patients had ORL release and 27 patients did not. Three independent masked experienced cosmetic surgeons reviewed preoperative and postoperative photographs to assess degree of swelling, ecchymosis, change in steatoblepharon and tear trough deformity, and overall aesthetic result...

The use of modern information and communication technologies (ICT) in daily life has significantly increased during the last several years. These essential online technologies have also found their way into the healthcare system. The use of modern ICT for health reasons can be summarized by the term 'eHealth'. Despite the potential importance of eHealth in the field of otorhinolaryngology (ORL), there is little understanding of patients' attitudes towards the deeper integration of these technologies into intersectoral care...

Hierarchical Temporal Memory (HTM) is an online machine learning algorithm that emulates the neo-cortex. The development of a scalable on-chip HTM architecture is an open research area. The two core substructures of HTM are spatial pooler and temporal memory. In this work, we propose a new Spatial Pooler circuit design with parallel memristive crossbar arrays for the 2D columns. The proposed design was validated on two different benchmark datasets, face recognition, and speech recognition. The circuits are simulated and analyzed using a practical memristor device model and 0...

BACKGROUND: Hawthorn is a popular herb in many different traditional medicine systems, including traditional Chinese medicine, where it has long been used for the treatment of hyperglycemia. However, most of its varied biological activities remain unexplored. This study investigated the hypoglycemic effect of hawthorn extracts in type II diabetic (T2DM) rat model. A total of 54 rats were randomly divided into six groups: normal control group; type II diabetic model group (T2DM; these rats were induced by high-fat diet and streptozotocin); high, middle and low concentrations of hawthorn treatment (HTH , HTM and HTL T2DM rats were given hawthorn extract at a dose of 50, 100 and 200 mg kg(-1) body weight, respectively); and positive control group (orlistat 40 mg kg(-1) body weight)...

PURPOSE: To evaluate the relationship between outer retinal layer (ORL) thickness in diabetic macular edema to visual acuity (VA). METHODS: Ninety-five eyes were included in this prospective nonrandomized case-control study. They divided into 30 cases of healthy normal subjects and 65 cases of nonproliferative diabetic retinopathy with diabetic macular edema. Complete ophthalmic examination and spectral domain-optical coherence tomography were done for all cases and analyzed to measure central foveal point thickness (CFT), ORL thickness at fovea, and subfoveal choroidal thickness...

Sen Yuan, Xia Mao, Lijiang Chen
In the last few years, great efforts have been made to extend the linear projection technique (LPT) for multidimensional data (i.e., tensor), generally referred to as the multilinear projection technique (MPT). The vectorized nature of LPT requires high-dimensional data to be converted into vector, and hence may lose spatial neighborhood information of raw data. MPT well addresses this problem by encoding multidimensional data as general tensors of a second or even higher order. In this paper, we propose a novel multilinear projection technique, called multilinear spatial discriminant analysis (MSDA), to identify the underlying manifold of high-order tensor data...

Pancreatic lipase (PL) is a primary lipase critical for triacylglyceride digestion in humans and is considered as a promising target for the treatment of obesity. Although the current synthetic drugs available for treating obesity have been demonstrated to be effective in inhibiting PL, their prolonged usage results in severe side effects. Based on this argument, in this study, we evaluated the structural and energetic features linked to molecular recognition between two well-known PL inhibitors, orlistat (ORL, synthetic inhibitor) and (-)-epigallocatechin gallate (EGCG, natural inhibitor) and PL through molecular dynamics simulations and free energy calculations of ORL and EGCG at the PL binding site when it is isolated (PL) from the heterodimer complex, forming the heterodimer complex with colipase (PLCL) and lacking structural calcium...

The aim of this study is to report our preliminary experiences with regard to safety and feasibility of three-dimensional (3D) endoscopic lacrimal surgeries with a recently launched latest generation 3D endoscope. A 4-mm rigid three-dimensional (3D) endoscope (TIPCAM 1S 3D ORL(R), Karl Storz, Tuttlingen, Germany) was used. Fifteen patients who underwent various endoscopic lacrimal procedures by a single surgeon (MJA) were included. The procedures included probing with nasolacrimal intubation, cruciate marsupialization of intranasal cysts for congenital dacryoceles, powered endoscopic dacryocystorhinostomy, post-operative stent removal with ostium granuloma excision...

Reelin is a regulator of cell migration in the nervous system, and has other functions in the development of a number of non-neuronal tissues. In addition, alterations in reelin expression levels have been reported in breast, pancreatic, liver, gastric, and other cancers. Reelin is normally expressed in mammary gland stromal cells, but whether stromal reelin contributes to breast cancer progression is unknown. Herein, we used a syngeneic mouse mammary tumor transplantation model to examine the impact of host-derived reelin on breast cancer progression...
