It is well known that dense coding with local bases (via Least Square coding schemes) can lead to large quantization errors or poor performances of machine learning tasks. On the other hand, sparse coding focuses on accurate representation without taking into account data locality due to its tendency to ignore the intrinsic structure hidden among the data. Local Hybrid Coding (LHC) (Xiang et al., 2014) was recently proposed as an alternative to the sparse coding scheme that is used in Sparse Representation Classifier (SRC)...

OBJECTIVES: Employing national registers for research purposes depends on a high diagnostic validity. The aim of the present study was to examine the diagnostic validity of recorded diagnoses of early-onset obsessive-compulsive disorder (OCD) in the Danish Psychiatric Central Register (DPCR). DESIGN: Review of patient journals selected randomly through the DPCR. METHOD: One hundred cases of OCD were randomly selected from DPCR. Using a predefined coding scheme based on the Children's Yale Brown Obsessive Compulsive Scale (CYBOCS), experienced research nurse or child and adolescent psychiatrists assessed each journal to determine the presence/absence of OCD diagnostic criteria...

PURPOSE: Tumor-associated macrophages (TAMs) are frequently associated with poor prognosis in human cancers. However, the effects of TAM in colorectal cancer (CRC) are contradictory. We therefore investigated the functions, mechanisms and clinical significance of TAMs in CRC. EXPERIMENTAL DESIGN: We measured the macrophage infiltration (CD68), P-gp and Bcl2 expression in CRC tissues using Immunohistochemistry staining. Co-culture of TAMs and CRC cells both in vitro and in vivo models was used to evaluate the effects of TAMs on CRC chemoresistance...

Primordial enzymes are proposed to possess broad specificities. Through divergence and evolution, enzymes have been refined to exhibit specificity towards one reaction or substrate, and are thus commonly assumed as "specialists". However, several enzymes are "generalists" that catalyze a range of substrates and reactions. This property has been defined as enzyme promiscuity and is of great importance for the evolution of new functions. The promiscuities of two enzymes, namely glycerol dehydratase and diol dehydratase, were herein exploited for catalyzing long-chain polyols, including 1,2-butanediol, 1,2,4-butanetriol, erythritol, 1,2-pentanediol, 1,2,5-pentanetriol, and 1,2,6-hexanetriol...

BACKGROUND: Obsessive Compulsive Disorder (OCD) is a chronic and disabling disorder with poor response to pharmacological treatments. Converging evidences suggest that OCD patients suffer from dysfunction of the cortico-striato-thalamo-cortical (CSTC) circuit, including in the medial prefrontal cortex (mPFC) and the anterior cingulate cortex (ACC). OBJECTIVE: To examine whether modulation of mPFC-ACC activity by deep transcranial magnetic stimulation (DTMS) affects OCD symptoms...

BACKGROUND: Pivotal clinical trials found ticagrelor reduced ischemic complications to a greater extent than clopidogrel and what is more, the benefit gradually increased with the reduction on creatinine clearance. However, the underlying mechanisms remains poorly explored. METHODS: This is a single-center, prospective, randomized clinical trial involving 60 hospitalized P2Y12 inhibitor naïve patients with CKD (eGFR<60ml/min/1.73m(2) ) and NSTE-ACS. Eligible patients were randomly assigned in a 1:1 ratio to receive ticagrelor(180 mg loading dose, then 90 mg twice daily followed) or clopidogrel(600 mg loading dose, then 75 mg qd followed)...

BACKGROUND: Numerous studies suggest that radiation can boost antitumor immune response by stimulating release of tumor-specific antigens. However, the optimal timing between radiotherapy and immune checkpoint blockade to achieve potentially synergistic benefits is unclear. MATERIAL AND METHODS: Multi-institutional retrospective analysis was conducted of ninety-nine metastatic melanoma patients from 2007 to 2014 treated with ipilimumab who later received stereotactic radiosurgery (SRS) for new brain metastases that developed after starting immunotherapy...

Wenjia Niu, Kewen Xia, Baokai Zu, Jianchuan Bai
Unlike Support Vector Machine (SVM), Multiple Kernel Learning (MKL) allows datasets to be free to choose the useful kernels based on their distribution characteristics rather than a precise one. It has been shown in the literature that MKL holds superior recognition accuracy compared with SVM, however, at the expense of time consuming computations. This creates analytical and computational difficulties in solving MKL algorithms. To overcome this issue, we first develop a novel kernel approximation approach for MKL and then propose an efficient Low-Rank MKL (LR-MKL) algorithm by using the Low-Rank Representation (LRR)...

The herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) is used worldwide. It has been associated with a variety of toxicities in rodents. In this study, male mice were orally administered 2,4-D at 50, 100 or 200mg/kg/day to investigate testicular toxicity and the possible mechanisms of action. Exposure to 2,4-D at high concentrations (100 and 200mg/kg/day) for 14 consecutive days caused spermatogenic disruption and seminiferous epithelial destruction. Furthermore, 2,4-D administration (100 and 200mg/kg/day) increased the formation of the lipid peroxidation product malondialdehyde and decreased activities of the antioxidant enzymes superoxide dismutase and catalase in the testis...

Food addiction is increasingly being recognised as a contributory factor in overweight and obesity. Management of eating compulsivity, a key component of food addiction, may assist greatly in the successful treatment of obesity. Measurement of food addiction and its core characteristic of eating compulsivity is fundamental to increasing understandings of the concept of food addiction, its prevalence among people with and without obesity and its utility within a treatment context. The current study describes the development and initial validation of a brief measure of eating compulsivity that can be used within clinical and research settings to establish a person's level of eating compulsivity...

Three-dimensional (3D) tumor spheroid models have gained increased recognition as important tools in cancer research and anti-cancer drug development. However, currently available imaging approaches employed in high-throughput screening drug discovery platforms e.g. bright field, phase contrast, and fluorescence microscopies, are unable to resolve 3D structures deep inside (>50 μm) tumor spheroids. In this study, we established a label-free, non-invasive optical coherence tomography (OCT) imaging platform to characterize 3D morphological and physiological information of multicellular tumor spheroids (MCTS) growing from ~250 μm up to ~600 μm in height over 21 days...

BACKGROUND: To isolate hospital effects on risk-standardized hospital-readmission rates, we examined readmission outcomes among patients who had multiple admissions for a similar diagnosis at more than one hospital within a given year. METHODS: We divided the Centers for Medicare and Medicaid Services hospital-wide readmission measure cohort from July 2014 through June 2015 into two random samples. All the patients in the cohort were Medicare recipients who were at least 65 years of age...

Historically, mRNA measurements have been tested on several commercially available platforms, but none have gained broad acceptance for assessment of HER2. An mRNA measurement, as a continuous value, has the potential for use in adjudication of the equivocal category. Here we use a real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR) assay in a closed, single-use cartridge, automated system. Multiple cores (1 mm in diameter) were retrospectively collected from 80 formalin-fixed paraffin-embedded (FFPE) tissue blocks with invasive breast cancer seen by Yale Pathology Labs between 1998 and 2011...

Type 2 diabetes mellitus (T2DM) is a common metabolic disease worldwide. It has been reported that irisin play regulatory role in glucose metabolism in T2DM. However, the underlying mechanism involved in that is not completely known. Herein, we determined the novel role of β-arrestin-2 in irisin-induced glucose utilization in diabetes. Effects of irisin and β-arrestin-2 on glucose utilization were investigated in a rat model of diabetes and in diabetic C2C12 cells in vitro. Results showed that irisin had positive role in glucose metabolism via regulating glucose tolerance as well as uptake in cardiac and skeletal muscle tissues, as evidenced by IPGTT, 2-deoxyglucose uptake and plasma membrane GLUT-4 assay...

BACKGROUND: Only a small fraction of acute chest pain in the emergency department (ED) is due to obstructive coronary artery disease (CAD). ED chest pain remains associated with high rates of recidivism, often in the presence of nonobstructive CAD. Psychological states such as depression, anxiety, and elevation of perceived stress may account for this finding. The objective of the study was to determine whether psychological states predict recurrent chest pain (RCP). METHODS: We conducted a prospective cohort study of low- to moderate-cardiac risk ED patients admitted to the Yale Chest Pain Center with acute chest pain...

Motivation: Systems immunology leverages recent technological advancements that enable broad profiling of the immune system to better understand the response to infection and vaccination, as well as the dysregulation that occurs in disease. An increasingly common approach to gain insights from these large-scale profiling experiments involves the application of statistical learning methods to predict disease states or the immune response to perturbations. However, the goal of many systems studies is not to maximize accuracy, but rather to gain biological insights...
