The role of brachial artery flow mediated dilation in diagnosis of reflex syncope

levels were increased. Despite exposure to contrast medium, CVCM and NCM groups did not differ in terms of histopathological findings from control group. In CV group, interstitial inflammation and other histopathological findings were remarkably lower compared to the C group. MDA levels were decreased and TAS levels were significantly increased in CVCM and NCM compared to the CM group. Although not statistically significant, levels of SOD increased in both group compared to CM group. Conclusion: This study demonstrated the protective role of carvedilol and nebivolol against CIN. Antioxidant properties of these drugs may have an effect in this.
SCVMJ , XX ( 2 ) 2015 271 Studies on Retail Chicken Meats With A Special Reference to Antibiotic Resistant Bacteria

This study was conducted on retail chicken meats to determine the prevalence of antibiotic resistant bacteria.The prevalence of antibiotic resistant bacteria in retail chicken meat was determined in hail region, Saudi Arabia. A total of 50 samples were collected and examined for the presence of antibiotic resistant bacteria. E. coli was the most prevalent isolates (48%) followed by S. aureus (24%) and Salmonella (20%). Some of them were multi-drug resistant (MDR). Resistance of S. aureus, E. coli and Salmonella spp. to tetracycline was most frequent at 25%, 79.16% and 60%, respectively. These findings suggest that the abundant presence of multi-drug resistant bacteria in the chicken meat may have a profound effect on future treatment options for a wide range of infections caused by bacteria.
Dynamic Personalized Search Based on RNN with Attention Mechanism

Traditional search engines always return the same result when facing the same query for different users. Therefore, when a user issues an ambiguous query, the search result can’t fully meet the user's demands. Personalized search is a practicable method to solve this problem. It has been proven to be able to improve the search quality of search engines. The majority of existing personalized search algorithms re-rank the original results by comparing the similarity between documents and user profiles built based on historical user behaviors. These behaviors contain a wealth of information to reflect the user personalized preferences. However, most of them generally believes that user interests are stable and unchanged for a long time, which is inconsistent with the actual situation. In this paper, we argue that user information needs might dynamically change over time and sometimes the user information needs are random. Therefore, the users’ recent search behaviors and the historical queries that are more similar to the current query contribute more to personalization than the others. This paper will take advantage of deep learning in feature extraction to build better user profiles.

Title On n-dependent groups and fields II Permalink

We continue the study of n-dependent groups, fields and related structures. We demonstrate that n-dependence is witnessed by formulas with all but one variable singletons, provide a type-counting criterion for 2-dependence and use it to deduce 2dependence for compositions of NIP relations with arbitrary binary functions. We prove a result on intersections of type-definable connected components over generic sets of parameters in n-dependent groups, generalizing Shelah’s results on absoluteness of G in NIP theories and relative absoluteness of G for 2-dependent theories. We show that Granger’s examples of non-degenerate bilinear forms over NIP fields are 2-dependent, and characterize preservation of n-dependence under expansion by generic relations for geometric theories in terms of disintegration of their algebraic closure. Finally, we show that every infinite n-dependent valued field of positive characteristic is henselian, generalizing a recent result of Johnson for NIP.
Feature Matching and Heat Flow in Centro-Affine Geometry

In this paper, we study the differential invariants and the invariant heat flow in centro-affine geometry, proving that the latter is equivalent to the inviscid Burgers' equation. Furthermore, we apply the centro-affine invariants to develop an invariant algorithm to match features of objects appearing in images. We show that the resulting algorithm compares favorably with the widely applied Scale-Invariant Feature Transform (SIFT), Speeded Up Robust Features (SURF), and Affine-SIFT (ASIFT) methods.
University of Birmingham TIE algorithm: A layer over clustering-based taxonomy generation for handling an evolving data

: Taxonomy is generated to effectively organize and access data that is large in volume, as taxonomy is a way of representing concepts that exist in data. It needs to be evolved to reflect changes occur continuously in data. Existing automatic taxonomy generation techniques do not handle the evolution of data, therefore their generated taxonomies do not truly represent the data. The evolution of data can be handled either by regenerating taxonomy from scratch, or incrementally evolving taxonomy whenever changes occur in the data. The former approach is not economical subject to time and resources. Taxonomy incremental evolution (TIE) algorithm, proposed in this paper, is a novel attempt to handle an evolving data. It serves as a layer over an existing clustering-based taxonomy generation technique and incrementally evolves an existing taxonomy. The algorithm was evaluated on scholarly articles selected from computing domain. It was found that the algorithm evolves taxonomy in a considerably shorter period of time, having better quality per unit time as compared to the taxonomy regenerated from scratch.
Eco-Innovation and its Determinants: A Review of the Emerging Literature

The aim of this paper is to enrich the existing research on eco-innovation and to provide an insight into the existing body of literature on eco-innovation determinants by analyzing the most significant publications in the area and the subjects of interest. The research adopts the document analysis method summarising definitions, classifications and recent developments in the area in order to develop insights into the evolution of eco-innovation and its main determinants. The findings are general and should be used by taking into account the specificity and local conditions within each country as well as the distinct environmental areas.
VARIATIONS ON A THEME:

This paper incorporates home production into a standard labor search-and-matching model. Incorporating information available from the American Time Use Survey, we find estimates of time spent at home production. Capturing these empirical measures as exogenous benefits received by unemployed workers, does not significantly increase the volatility generated by a standard model. We show, however, that endogenous home production acts as an amplification mechanism, considerably improving the ability of a standard model in generating fluctuations of labor market variables.

Title Estimation of Citrus Maturity with Fluorescence Spectroscopy Using Deep Learning

To produce high-quality citrus, the harvest time of citrus should be determined by considering its maturity. To evaluate citrus maturity, the Brix/acid ratio, which is the ratio of sugar content or soluble solids content to acid content, is one of the most commonly used indicators of fruit maturity. To estimate the Brix/acid ratio, fluorescence spectroscopy, which is a rapid, sensitive, and cheap technique, was adopted. Each citrus peel was extracted, and its fluorescence value was measured. Then, the fluorescent spectrum was analyzed using a convolutional neural network (CNN). In fluorescence spectroscopy, a matrix called excitation and emission matrix (EEM) can be obtained, in which each fluorescence intensity was recorded at each excitation and emission wavelength. Then, by regarding the EEM as an image, the Brix/acid ratio of juice from the flesh was estimated via performing a regression with a CNN (CNN regression). As a result, the Brix/acid ratio absolute error was estimated to be 2.48, which is considerably better than the values obtained by the other methods in previous studies. Hyperparameters, such as depth of layers, learning rate, and the number of filters used for this estimation, could be observed using Bayesian optimization, and the optimization contributed to the high accuracy.
An efficient leg with series–parallel and biarticular compliant actuation: design optimization, modeling, and control of the eLeg

We present the development, modeling, and control of a three-degree-of-freedom compliantly actuated leg called the eLeg, which employs both series- and parallel-elastic actuation as well as a bio-inspired biarticular tendon. The leg can be reconfigured to use three distinct actuation configurations, to directly compare with a state-of-the-art series-elastic actuation scheme. Critical actuation design parameters are derived through optimization. A rigorous modeling approach is presented using the concept of power flows, which are also used to demonstrate the ability to transfer mechanical power between ankle and knee joints using the biarticular tendon. The design principles and control strategies were verified both in simulation and experiment. Notably, the experimental data demonstrate significant improvements of 65–75% in electrical energy consumption compared with a state-of-the-art series-elastic actuator configuration.
CONSTRUCTIONISM AND SENIOR SECONDARY STUDENTS’ LEARNING ACHIEVEMENT IN SOLID GEOMETRY

This study investigated the effects of Constructionist Class of Instructional (2CI) models on Solid Geometry Achievement (SGA) of Senior Secondary Class I (SSC1) students in Emohua Local Government Area (LGA) of Rivers State, Nigeria. The specific 2CI-models used in this study were Design-Based Learning (DBL) and Learning-While-Doing (LWD) instructional models. A quasi-experimental design was used. A total of 89 SSCI students took part in the study. Solid Geometry Achievement Test (SGAT) was used to measure student SGA. The KR-21 was used to determine the reliability of the SGAT and an index of 0.84 was obtained. The study was guided by two research questions and two hypotheses respectively. The descriptive statistic and Analysis of Covariance (ANCOVA) were used for data analysis. The study found that the 2CI-models advanced the SGLA of students over time. The DBL proved to be fairly superior the LWD over learning gain. The 2CI-models had a significant effect on the SGLA of the students. There was a significant main effect of 2CI-models over Problem-based Learning (PbL) model on SGLA of SSC1 students. There was no significant difference between the mean SGLA scores of the male and the female students instructed using 2CI-models over PbL model. The study recommended among others the adoption of 2CI-models in teaching mathematics since it has been proven to aid students to own and apply their knowledge. Article visualizations:
The impact of diabetes mellitus medication on the incidence of endogenous endophthalmitis

Purpose This study aimed to evaluate the relationship between diabetic mellitus (DM) treatment and the incidence rate of endogenous endophthalmitis (EE). Design This study used a matched cohort design. We utilized the Longitudinal Health Insurance Database to identify outpatients and inpatients who were diagnosed with DM and treated with medication from 2000 to 2010. Methods Several factors and different DM medications were also investigated. The influence of DM medication on the incidence of EE was examined by using Cox proportional hazards regression models, and the hazard ratios and 95% confidence intervals were determined. Results The cumulative incidence of EE was lower in DM patients treated with medication than in subjects in the control group (P = 0.002). The adjusted hazard ratio (AHR) was 0.47-fold lower in the treatment group than in the control group (P = 0.004). With respect to DM medication, single-agent therapy with insulin, metformin, gliclazide, glimepiride, or repaglinide and combination therapy with glimepiride/metformin or repaglinide/metformin were associated with decreased AHRs (0.257–0.544, all P<0.05). Conclusions Diabetic patients treated with medication had lower AHRs than those in the control group. Further stratification indicated that liver abscess, liver disease DM patients who were treated with medication had a lower risk of developing EE. Several specific DM medications may decrease the incidence of EE.
Warming counteracts defoliation‐induced mismatch by increasing herbivore‐plant phenological synchrony

Climate change is altering phenology; however, the magnitude of this change varies among taxa. Compared with phenological mismatch between plants and herbivores, synchronization due to climate has been less explored, despite its potential implications for trophic interactions. The earlier budburst induced by defoliation is a phenological strategy for plants against herbivores. Here, we tested whether warming can counteract defoliation‐induced mismatch by increasing herbivore‐plant phenological synchrony. We compared the larval phenology of spruce budworm and budburst in balsam fir, black spruce, and white spruce saplings subjected to defoliation in a controlled environment at temperatures of 12, 17, and 22°C. Budburst in defoliated saplings occurred 6–24 days earlier than in the controls, thus mismatching needle development from larval feeding. This mismatch decreased to only 3–7 days, however, when temperatures warmed by 5 and 10°C, leading to a resynchronization of the host with spruce budworm larvae. The increasing synchrony under warming counteracts the defoliation‐induced mismatch, disrupting trophic interactions and energy flow between forest ecosystem and insect populations. Our results suggest that the predicted warming may improve food quality and provide better growth conditions for larval development, thus promoting longer or more intense insect outbreaks in the future.
Tuberculous arthritis in a patient with rheumatoid arthritis treated with methotrexate alone

An 81-year-old woman who had been treated since 1994 with methotrexate (MTX) monotherapy (10 mg/week) for rheumatoid arthritis (RA) was referred to a tertiary hospital for worsening arthritis of hands and knees for about 1 year. She had a history of primary osteoarthritis and of tuberculosis,
Covers.

A purely local approach has been developed by Krishnamurthy and Kutzko to compute Langlands-Shahidi local coeﬃcient for SL(2) via Bushnell-Kutzko’s types and covers. We extend their method to the non-split case. In the course of computation, we also investigate the structure of Gelfand-Graev space, which generalizes the results of Chan-Savin and Mishra-Pattanayak for SL(2). Turning to the case of the Siegel Levi subgroup inside Sp(2 n ), we establish that Langland-Shahidi local exterior square γ -factors for level zero supercuspidal representations of GL( n ) agree with those through Jacquet-Shalika integrals in characteristic 0, and Bump-Friedberg and Jacquet-Shalika integrals in characteristic p > 0. Furthermore, all our analysis support Bump and Friedberg conjecture.
Delayed skin necrosis following hyaluronic acid filler injection: A case report

Vascular compromise is a rare but serious complication of dermal filler injection. Vessel occlusion tends to have a more immediate onset of symptoms. We report a case of skin necrosis that started with pain, erythema and edema two days after hyaluronic acid filler on the forehead of a 57‐year‐old woman. The patient was treated with less than 24 hours the onset of symptoms, leaving discreet scar. The current theories that explain skin necrosis caused by HA fillers include angiospasm and embolization. The frontal region has many anastomoses, the embolized proximal vessel initially did not lead to symptoms. However, the HA inside the artery may have traveled over time and reached a terminal distal branch, which generated localized skin damage and pain. The urgent treatment of arterial occlusion and thromboembolism caused by HA injection is intralesional high‐dose hyaluronidase.
Role of noncanonical Wnt ligands and Ror‐family receptor tyrosine kinases in the development, regeneration, and diseases of the musculoskeletal system

The Ror‐family receptor tyrosine kinases (RTKs), consisting of Ror1 and Ror2, play crucial roles in morphogenesis and formation of various tissues/organs, including the bones and skeletal muscles, the so‐called musculoskeletal system, during embryonic development, by acting as receptors or coreceptors for a noncanonical Wnt protein Wnt5a. Furthermore, several lines of evidence have indicated that Ror1 and/or Ror2 play critical roles in the regeneration and maintenance of the musculoskeletal system in adults. Considering the anatomical and functional relationship between the skeleton and skeletal muscles, their structural and functional association might be tightly regulated during their embryonic development, development after birth, and their regeneration after injury in adults. Importantly, in addition to their congenital anomalies, much attention has been paid onto the age‐related disorders of the musculoskeletal system, including osteopenia and sarcopenia, which affect severely the quality of life. In this article, we overview recent advances in our understanding of the roles of Ror1‐ and/or Ror2‐mediated signaling in the embryonic development, regeneration in adults, and congenital and age‐related disorders of the musculoskeletal system and discuss possible therapeutic approaches to locomotive syndromes by modulating Ror1‐ and/or Ror2‐mediated signaling.
A nod to gut–brain signalling: Nod‐like receptors are critical for gut–brain axis signalling in mice

Exposure to highly stressful events in early life can impact gastrointestinal (GI) function and increase an individual’s probability of developing an inflammatory bowel disease (IBD) as an adult. For example, exposure to trauma early in life induces visceral hypersensitivity and increases gut permeability in adulthood. The mechanism for this change likely involves the hypothalamic–pituitary–adrenal axis, as individuals exposed to stress show an enduring hyper-responsiveness, and GI changes have been found to be closely mediated by corticotropin releasing factor, as well as nerve growth factor and mast cells (Theodorou, 2013). Gut–brain axis signalling in inflammatory diseases likely involves serotonergic signalling, as levels of 5-HT are elevated in inflamed mucosa from Crohn’s disease patients and in animal models of other IBDs. A mouse model deficient for the expression of tryptophan hydroxylase 1 – the enzyme responsible for the production of 5-HT in intestinal epithelia – shows a protective effect from developing colitis in two different chemical models. Mice deficient for serotonin reuptake transporter (SERT) develop more severe colitis in both chemical and transgenic animal models of the disease (Levin & van den Brink, 2014). Nucleotide oligomerization domain 1 (Nod1) is a cytosolic receptor responsible for triggering an innate immune response to antigens present within the cytoplasm. An
Reported Prevalence of Maternal Hepatitis C Virus Infection in the United States.

OBJECTIVE To quantify the reported prevalence and trend of maternal hepatitis C virus (HCV) infection in the United States (2009-2017) and identify maternal characteristics and obstetric outcomes associated with HCV infection during pregnancy. METHODS We conducted a population-based retrospective cohort study of all live births in the United States for the period 2009 through 2017 using National Center for Health Statistics birth records. We estimated reported prevalence and trends over this time period for the United States. We also evaluated demographic factors and pregnancy outcomes associated with maternal HCV infection for a contemporary U.S. cohort (2014-2017). RESULTS During the 9-year study period, there were 94,824 reported cases of maternal HCV infection among 31,207,898 (0.30%) live births in the United States. The rate of maternal HCV infection increased from 1.8 cases per 1,000 live births to 4.7 cases per 1,000 live births (relative risk [RR] 2.7, 95% CI 2.6-2.8) in the United States. After adjusting for various confounders in the contemporary U.S. cohort (2014-2017), demographic characteristics associated with HCV infection included non-Hispanic white race (adjusted RR 2.8, 95% CI 2.7-2.8), Medicaid insurance (adjusted RR 3.3, CI 3.2-3.3), and cigarette smoking (adjusted RR 11.1, CI 10.9-11.3). Co-infection during pregnancy with hepatitis B (adjusted RR 19.2, CI 18.1-20.3), gonorrhea, chlamydia, or syphilis were also associated with maternal HCV infection. Obstetric and neonatal outcomes associated with maternal HCV infection included cesarean delivery, preterm birth, maternal intensive care unit admission, blood transfusion, having small-for-gestational-age neonates (less than the 10th percentile) birth weight, neonatal intensive care unit admission, need for assisted neonatal ventilation, and neonatal death. CONCLUSION The reported prevalence of maternal HCV infection has increased 161% from 2009 to 2017.
The study of Lynch syndrome in a special population reveals a strong founder effect and an unusual mutational mechanism in familial adenomatous polyposis

We read with interest the study by Moller and colleagues.1 The isolation and relative homogeneity of the Saudi population enhance the potential to discover founder mutations, while its high rates of consanguinity enhances homozygosity even for typically dominant disease genes.2 3 We have previously explored the contribution of Lynch syndrome (LS) to colorectal cancer (CRC) based on ~800 Saudi patients.4 We have since expanded our cohort to 1207 CRC patients. Of the 112 mismatch repair deficient (dMMR) cases, MMR gene mutations were identified in 26 cases and these varied in their cancer risk by age 50 years (figure 1). Three founder mutations were observed, accounting for 42.3% (n=11) of LS cases, and none is listed in gnomAD. The PMS2 :c.1376C>G;p.S459X variant was the most commonly encountered LS variant (n=6), and we calculated its minor allele frequency at 0.0001. ​ Importantly, we were able to identify a homozygous individual for PMS2 :c.1376C>G;p.S459X through a large scale whole-exome sequencing (WES) study.2 This individual presented at age 8 years with haematochezia and a typical picture of familial adenomatous …
A biotechnology‐based male‐sterility system for hybrid seed production in tomato

Summary Incorporating male sterility into hybrid seed production reduces its cost and ensures high varietal purity. Despite these advantages, male‐sterile lines have not been widely used to produce tomato (Solanum lycopersicum) hybrid seeds. We describe the development of a biotechnology‐based breeding platform that utilized genic male sterility to produce hybrid seeds. In this platform, we generated a novel male‐sterile tomato line by clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR‐associated protein 9 (Cas9)‐mediated mutagenesis of a stamen‐specific gene SlSTR1 and devised a transgenic maintainer by transforming male‐sterile plants with a fertility‐restoration gene linked to a seedling‐colour gene. Offspring of crosses between a hemizygous maintainer and the homozygous male‐sterile plant segregated into 50% non‐transgenic male‐sterile plants and 50% male‐fertile maintainer plants, which could be easily distinguished by seedling colour. This system has great practical potential for hybrid seed breeding and production as it overcomes the problems intrinsic to other male‐sterility systems and can be easily adapted for a range of tomato cultivars and diverse vegetable crops.
