Authors: Lao Hio Kuan , Tan Jingyun , Wang Chunfei , Zhang Xuanjun
Published: September 2019

Peroxynitrite (ONOO−) is one of the sources of oxidation stress involved in many biological signaling pathways. The role of ONOO− being a double-edged sword in biological systems drives the development of effective detection tools. In this work, a boronate-based polymeric fluorescent probe PB-PVA was synthesized and the probe performance was evaluated. The probe exhibits ratiometric sensing of ONOO− in a range of 0–6 µM. There is good linear relationship between the probe fluorescence intensity ratio and ONOO− concentration. The probe also displays moderate selectivity towards ONOO− over other ROS. Moreover, it is water-soluble and possesses good biocompatibility which aids the imaging of ONOO− in living cells. These properties could make the probe a promising tool in in vitro study related to ONOO−.

Published: September 2019

Perovskite solar cells (PSCs) have achieved tremendous success within just a decade. This success is critically dependent upon compositional engineering, morphology control of perovskite layer, or contingent upon high-temperature annealed mesoporous TiO2, but quantitative analysis of the role of facile TiCl4 treatment and thickness control of the compact TiO2 layer has not been satisfactorily undertaken. Herein, we report the facile thickness control and post-treatment of the electron transport TiO2 layer to produce highly efficient planar PSCs. TiCl4 treatment of TiO2 layer could remove the surface trap and decrease the charge recombination in the prepared solar cells. Introduction of ethanol into the TiCl4 aqueous solution led to further improved open-circuit voltage and short-circuit current density of the related devices, thus giving rise to enhanced power conversion efficiency (PCE). After the optimal TiCl4 treatment, PCE of 16.42% was achieved for PSCs with TiCl4 aqueous solution-treated TiO2 and 19.24% for PSCs with TiCl4 aqueous/ethanol solution-treated TiO2, respectively. This work sheds light on the promising potential of simple planar PSCs without complicated compositional engineering and avoiding the deposition and optimization of the mesoporous scaffold layer.

Published: September 2019

The consumption of an olive oil rich diet has been associated with the diminished incidence of cardiovascular disease and cancer. Several studies have attributed these beneficial effects to oleic acid (C18 n-9), the predominant fatty acid principal component of olive oil. Oleic acid is not an essential fatty acid since it can be endogenously synthesized in humans. Stearoyl-CoA desaturase 1 (SCD1) is the enzyme responsible for oleic acid production and, more generally, for the synthesis of monounsaturated fatty acids (MUFA). The saturated to monounsaturated fatty acid ratio affects the regulation of cell growth and differentiation, and alteration in this ratio has been implicated in a variety of diseases, such as liver dysfunction and intestinal inflammation. In this review, we discuss our current understanding of the impact of gene-nutrient interactions in liver and gut diseases, by taking advantage of the role of SCD1 and its product oleic acid in the modulation of different hepatic and intestinal metabolic pathways.

Published: September 2019

Silymarin is a traditional drug and food supplement employed for numerous liver disorders. The available studies indicate that its activities may be broader, in particular due to claimed benefits in some cardiovascular diseases, but the contributions of individual silymarin components are unclear. Therefore, we tested silymarin flavonolignans as pure diastereomers as well as their sulfated metabolites for potential vasorelaxant and antiplatelet effects in isolated rat aorta and in human blood, respectively. Eleven compounds from a panel of 17 tested exhibited a vasorelaxant effect, with half maximal effective concentrations (EC50) ranging from 20 to 100 µM, and some substances retained certain activity even in the range of hundreds of nM. Stereomers A were generally more potent as vasorelaxants than stereomers B. Interestingly, the most active compound was a metabolite—silychristin-19-O-sulfate. Although initial experiments showed that silybin, 2,3-dehydrosilybin, and 2,3-dehydrosilychristin were able to substantially block platelet aggregation, their effects were rapidly abolished with decreasing concentration, and were negligible at concentrations ≤100 µM. In conclusion, metabolites of silymarin flavonolignans seem to have biologically relevant vasodilatory properties, but the effect of silymarin components on platelets is low or negligible.

Published: September 2019

We investigated and monitored in situ the wetting and dissolution properties of polymeric nanofibers and determined the solid-state of a drug during dissolution. Piroxicam (PRX) was used as a low-dose and poorly-soluble model drug, and hydroxypropyl methylcellulose (HPMC) and polydextrose (PD) were used as carrier polymers for electrospinning (ES). The initial-stage dissolution of the nanofibers was monitored in situ with three-dimensional white light microscopic interferometry (SWLI) and high-resolution optical microscopy. The physical solid-state characterization of nanofibers was performed with Raman spectroscopy, X-ray powder diffraction (XRPD), and scanning electron microscopy (SEM). We showed that PRX recrystallizes in a microcrystalline form immediately after wetting of nanofibers, which could lead to enhanced dissolution of drug. Initiation of crystal formation was detected by SWLI, indicating: (1) that PRX was partially released from the nanofibers, and (2) that the solid-state form of PRX changed from amorphous to crystalline. The amount, shape, and size of the PRX crystals depended on the carrier polymer used in the nanofibers and dissolution media (pH). In conclusion, the present nanofibers loaded with PRX exhibit a quasi-dynamic dissolution via recrystallization. SWLI enables a rapid, non-contacting, and non-destructive method for in situ monitoring the early-stage dissolution of nanofibers and regional mapping of crystalline changes (re-crystallization) during wetting. Such analysis is crucial because the wetting and dissolution of nanofibers can greatly influence the performance of nanofibrous drug delivery systems in pharmaceutical and biomedical applications.
A Machine Learning Approach for Improving Near-Real-Time Satellite-Based Rainfall Estimates by Integrating Soil Moisture
Authors: Kumar Ashish , Ramsankaran RAAJ , Brocca Luca , Munoz-Arriola Francisco
Published: September 2019

Near-real-time (NRT) satellite-based rainfall estimates (SREs) are a viable option for flood/drought monitoring. However, SREs have often been associated with complex and nonlinear errors. One way to enhance the quality of SREs is to use soil moisture information. Few studies have indicated that soil moisture information can be used to improve the quality of SREs. Nowadays, satellite-based soil moisture products are becoming available at desired spatial and temporal resolutions on an NRT basis. Hence, this study proposes an integrated approach to improve NRT SRE accuracy by combining it with NRT soil moisture through a nonlinear support vector machine-based regression (SVR) model. To test this novel approach, Ashti catchment, a sub-basin of Godavari river basin, India, is chosen. Tropical Rainfall Measuring Mission (TRMM) Multisatellite Precipitation Analysis (TMPA)-based NRT SRE 3B42RT and Advanced Scatterometer-derived NRT soil moisture are considered in the present study. The performance of the 3B42RT and the corrected product are assessed using different statistical measures such as correlation coefficient (CC), bias, and root mean square error (RMSE), for the monsoon seasons of 2012–2015. A detailed spatial analysis of these measures and their variability across different rainfall intensity classes are also presented. Overall, the results revealed significant improvement in the corrected product compared to 3B42RT (except CC) across the catchment. Particularly, for light and moderate rainfall classes, the corrected product showed the highest improvement (except CC). On the other hand, the corrected product showed limited performance for the heavy rainfall class. These results demonstrate that the proposed approach has potential to enhance the quality of NRT SRE through the use of NRT satellite-based soil moisture estimates.
Impacts of AOD Correction and Spatial Scale on the Correlation between High-Resolution AOD from Gaofen-1 Satellite and In Situ PM2.5 Measurements in Shenzhen City, China
Authors: Wu Jiansheng , Liang Jingtian , Zhou Liguo , Yao Fei , Peng Jian
Published: September 2019

Satellite-derived aerosol optical depth (AOD) is widely used to estimate surface PM2.5 concentrations. Most AOD products have relatively low spatial resolutions (i.e., ≥1 km). Consequently, insufficient research exists on the relationship between high-resolution (i.e., <1 km) AOD and PM2.5 concentrations. Taking Shenzhen City, China as the study area, we derived AOD at the 16-m spatial resolution for the period 2015–2017 based on Gaofen-1 (GF-1) satellite images and the Dark Target (DT) algorithm. Then, we extracted AOD at spatial scales ranging from 40 m to 5000 m and applied vertical and humidity corrections. We analyzed the correlation between AOD and PM2.5 concentrations, and the impacts of AOD correction and spatial scale on the correlation. It was found that the DT-derived GF-1 AOD at different spatial scales had statistically significant correlations with surface PM2.5 concentrations, and the AOD corrections strengthened the correlations. The correlation coefficients (R) between AOD at different spatial scales and PM2.5 concentrations were 0.234–0.329 and 0.340–0.423 before and after AOD corrections, respectively. In spring, summer, autumn, and winter, PM2.5 concentrations had the best correlations with humidity-corrected AOD, uncorrected AOD, vertical and humidity-corrected AOD, and uncorrected AOD, respectively, indicating a distinct seasonal variation of the aerosol characteristics. At spatial scales of 1–5 km, AOD at finer spatial scales generally had higher correlations with PM2.5 concentrations. However, at spatial scales <1 km, the correlations fluctuated irregularly, which could be attributed to scale mismatches between AOD and PM2.5 measurements. Thus, 1 km appears to be the optimum spatial scale for DT-derived AOD to maximize the correlation with PM2.5 concentrations. It is also recommended to aggregate very high-resolution DT-derived AOD to an appropriate medium resolution (e.g., 1 km) before matching them with in situ PM2.5 measurements in regional air pollution studies.

Published: September 2019

The fields of human activity analysis have recently begun to diversify. Many researchers have taken much interest in developing action recognition or action prediction methods. The research on human action evaluation differs by aiming to design computation models and evaluation approaches for automatically assessing the quality of human actions. This line of study has become popular because of its explosively emerging real-world applications, such as physical rehabilitation, assistive living for elderly people, skill training on self-learning platforms, and sports activity scoring. This paper presents a comprehensive survey of approaches and techniques in action evaluation research, including motion detection and preprocessing using skeleton data, handcrafted feature representation methods, and deep learning-based feature representation methods. The benchmark datasets from this research field and some evaluation criteria employed to validate the algorithms’ performance are introduced. Finally, the authors present several promising future directions for further studies.

Authors: Kopaczka Marcin , Breuer Lukas , Schock Justus , Merhof Dorit
Published: September 2019

We present a system that utilizes a range of image processing algorithms to allow fully automated thermal face analysis under both laboratory and real-world conditions. We implement methods for face detection, facial landmark detection, face frontalization and analysis, combining all of these into a fully automated workflow. The system is fully modular and allows implementing own additional algorithms for improved performance or specialized tasks. Our suggested pipeline contains a histogtam of oriented gradients support vector machine (HOG-SVM) based face detector and different landmark detecion methods implemented using feature-based active appearance models, deep alignment networks and a deep shape regression network. Face frontalization is achieved by utilizing piecewise affine transformations. For the final analysis, we present an emotion recognition system that utilizes HOG features and a random forest classifier and a respiratory rate analysis module that computes average temperatures from an automatically detected region of interest. Results show that our combined system achieves a performance which is comparable to current stand-alone state-of-the-art methods for thermal face and landmark datection and a classification accuracy of 65.75% for four basic emotions.
Lorry Park Selection Criteria and Drivers’ Preferences: A Study from the UK
Authors: García-Gallego José Manuel , Kang Taeun , Rubio Lacoba Sergio , Genovese Andrea
Published: September 2019

Increasing urbanization and economic activities has intensified the need for logistical processes in cities. This leads to higher levels of urban freight transport, which is associated with negative social and environmental impacts. Advances in urban logistics can help to alleviate these problems; the recent literature suggests that the creation of appropriate lorry park facilities can represent one of the possible solutions to the social and environmental issues connected to freight transport in urban areas. However, in order to be effective, such facilities need to be properly designed; studies which identify critical success factors for lorry park operations are currently lacking. As such, the purpose of this research is to identify the main criteria which lorry drivers consider when selecting a lorry park facility. In order to achieve these aims, a questionnaire survey was designed; responses from 99 lorry drivers operating in the United Kingdom were collected. Through descriptive statistics, followed by the usage of a conjoint analysis, the main results show that attributes related to food, price, and security are the most important to lorry drivers and are likely to determine the success of such initiatives. These results can provide information to policy and decision-makers related to the design of lorry park facilities in order to achieve the desired results in urban areas.
Urban Informality in the Paris Climate Agreement: Content Analysis of the Nationally Determined Contributions of Highly Urbanized Developing Countries
Authors: Núñez Collado Jose Rafael , Wang Han-Hsiang , Tsai Tsung-Yi
Published: September 2019

Climate change related events affect informal settlements, or slums, disproportionally more than other areas in a city or country. This article investigates the role of slums in the nationally determined contributions (NDCs) for the Paris Agreement of a selected group of 28 highly urbanized developing countries. Content analysis and descriptive statistics were used to analyze first the general content in these NDCs and second the proposed role, or lack thereof, of slums in these documents. The results show that for most of the analyzed countries, context-based climate policies for slums are not part of the strategies presented in the NDCs. We argue that a lack of policies involving informal settlements might limit the capacity of developing countries to contribute to the main goals of the Paris Agreement, as these settlements are significant portions of their urban populations. One of the hopeful prospects of the NDCs is that they will be reviewed in 2020 for the 26th Conference of the Parties (COP26). With this paper, we aim to stimulate discussions about the crucial role that informal settlements should play in the NDCs of developing countries in the background of the synergies required between climate change actions and sustainable development.

Published: September 2019

The development of advanced technologies has led to the emergence of autonomous vehicles. Herein, autonomous public transport (APT) systems equipped with prioritization measures are being designed to operate at ever faster speeds compared to conventional buses. Innovative APT systems are configured to accommodate prevailing passenger demand for peak as well as non-peak periods, by electronic coupling and decoupling of platooned units along travel corridors, such as the dynamic autonomous road transit (DART) system being researched in Singapore. However, there is always the trade-off between high vehicle speed versus passenger ride comfort, especially lateral ride comfort. This study analyses a new APT system within the urban context and evaluates its performance using microscopic traffic simulation. The platooning protocol of autonomous vehicles was first developed for simulating the coupling/decoupling process. Platooning performance was then simulated on VISSIM platform for various scenarios to compare the performance of DART platooning under several ride comfort levels: three bus comfort and two railway criteria. The study revealed that it is feasible to operate the DART system following the bus standing comfort criterion (ay = 1.5 m/s2) without any significant impact on system travel time. For the DART system operating to maintain a ride comfort of the high-speed train (HST) and light rail transit (LRT), the delay can constitute up to ≈ 10% and ≈ 5% of travel time, respectively. This investigation is crucial for the system delay management towards precisely designed service frequency and improved passenger ride comfort.
Social Learning for Facilitating Dialogue and Understanding of the Ecosystem Services Approach: Lessons from a Cross-Border Experience in the Alboran Marine Basin
Authors: López-Rodríguez María D. , Cabello Javier , Castro Hermelindo , Rodríguez Jaime
Published: September 2019

Social learning (SL) appears to have considerable potential to enhance the impact of the ecosystem services approach (ESA) discourse on policy and society. However, empirical research to better understand the processes that support SL, the effects it generates, and the conditions that enable such learning is limited. This study assesses the ability of SL to enhance dialogue and understanding of the ESA to support transformative social change in governance practice in the Alboran Marine Basin. To do so, we conducted a specifically designed SL process oriented towards the ESA as a governance approach in this marine region. The SL process was developed through three interlinked workshops involving scientists, decision-makers and local users from Spain and Morocco, the two countries that share the governance of this social-ecological system. The results revealed that the SL process progressively facilitated (i) a more inclusive and constructive ecosystem services dialogue, (ii) a better understanding of the social-ecological system in which the actors were embedded, (iii) an enhanced recognition of science-policy-society complementarities to address sustainability issues, and (iv) a gradual social transformation towards more sustainable and equitable governance. Via the SL process, a variety of factors were identified as contributing to the creation of four relevant conditions that facilitated its successful operationalisation. These conditions included (i) the generation of trust and shared understanding, (ii) the facilitation of knowledge exchanges between actor groups across frontiers, (iii) the promotion of more democratic participation, and (iv) the co-production of practical outcomes. These contextual insights provided empirical evidence of the prominent role SL can play to enhance dialogue and understanding of the ESA for supporting its adoption as governance practice. On this basis, it is argued that operationalising SL in those processes focused on making the ESA relevant to policy and society is pivotal to its implementation in governance practice.
Steric Sea Level Changes from Ocean Reanalyses at Global and Regional Scales
Authors: Storto Andrea , Bonaduce Antonio , Feng Xiangbo , Yang Chunxue
Published: September 2019

Sea level has risen significantly in the recent decades and is expected to rise further based on recent climate projections. Ocean reanalyses that synthetize information from observing networks, dynamical ocean general circulation models, and atmospheric forcing data offer an attractive way to evaluate sea level trend and variability and partition the causes of such sea level changes at both global and regional scales. Here, we review recent utilization of reanalyses for steric sea level trend investigations. State-of-the-science ocean reanalysis products are then used to further infer steric sea level changes. In particular, we used an ensemble of centennial reanalyses at moderate spatial resolution (between 0.5 × 0.5 and 1 × 1 degree) and an ensemble of eddy-permitting reanalyses to quantify the trends and their uncertainty over the last century and the last two decades, respectively. All the datasets showed good performance in reproducing sea level changes. Centennial reanalyses reveal a 1900–2010 trend of steric sea level equal to 0.47 ± 0.04 mm year−1, in agreement with previous studies, with unprecedented rise since the mid-1990s. During the altimetry era, the latest vintage of reanalyses is shown to outperform the previous ones in terms of skill scores against the independent satellite data. They consistently reproduce global and regional upper ocean steric expansion and the association with climate variability, such as ENSO. However, the mass contribution to the global mean sea level rise is varying with products and its representability needs to be improved, as well as the contribution of deep and abyssal waters to the steric sea level rise. Similarly, high-resolution regional reanalyses for the European seas provide valuable information on sea level trends, their patterns, and their causes.
Ministering to Other People's Fears: Effects of Anti-Muslim Hostility on American Muslim Participation in Public Life
Authors: Elfenbein Caleb
Published: September 2019

This article explores the manifestations and effects of anti-Muslim hostility in the United States, asking how anti-Muslim hostility affects the nature of American Muslim participation in public life. It argues that cultural trauma among American Muslim communities, resulting from an expectation of routine harm, conditions the nature of participation in public life undertaken by many American Muslims. Drawing on original datasets documenting anti-Muslim hostility and outreach efforts undertaken by American Muslim communities, we can see that ministering to non-Muslim fears has become a central element of participation in public life. This burden of “humanization” pushes us to consider central elements of American “freedom mythologies” around public life and to ask what responsibility non-Muslims have in advocacy work on behalf of American Muslim communities.

Dc motor is widely used as actuator in industry and robotics. In this experiment a dc motor is used as an Omni wheel actuator on Omni-directional 3WD robot. In order for the movement of the robot to follow the specified vector quantity, then the speed of the wheels connected in each motor shaft must persist at each set of points that have been determined. For these needs then, every dc motor must be controlled the number of revolutions. One of the problems with implementing a PID controller is the possibility of a wind-up integrator effect that causes the system to be unable to follow the command behavior. The purpose of this study was to obtain PID controller parameters in such a way as to avoid the effects of wind-up integrators and achieve the best system response performance using an experimental based heuristic approach. The results of this study show that the wheel spin is able to follow various reference speeds with settling time and steady state error at about 1.1s and 0.648%.

Today, the use of mobile devices such as smartphones and tablets has become truly ubiquitous. This has created an opportunity for mobile learning to prosper. Mobile learning applications have become so popular that there are thousands of developers and tens of thousands of educational apps on numerous subjects, including language learning, which can be easily downloaded and installed on mobile devices. One area of interest for Muslims is Quranic Arabic vocabulary learning. This qualitative exploratory study aims to examine all Quranic Arabic vocabulary learning applications provided on the Google Play Store website through content analysis in order to determine their features and the teaching activities. Data was gathered both from the ‘product detail’ page on the Play Store and from the testing of the application by the researchers. The findings of this study indicate that most Quranic Arabic vocabulary mobile apps deliver their lessons through a textual interface though there are several apps which also include pictures, audio, and videos in their lessons. Many apps also provide exercises in the form of translation, matching items, and sentence completion. However, only four apps provide assessments. As a conclusion, this exploratory study has shed some light on the current state of Quranic Arabic vocabulary mobile apps in terms of their features and activities and it is hoped that more apps will be developed in the near future to cater to the needs of millions of Muslim adults who want to improve their devotional practices.

Requirements Engineering phase is well recognized as a root of Software Development Life Cycle (SDLC) by research community. Requirements are elucidated through requirements elicitation methods conceded by requirement analyst. Requirements elicitation phase is planned and strategized to get complete acquaintance about user’s requirements and expectations. Current software industries having massive necessity to help requirements analyst in requirements elicitation process to carry out precise manner. Correct and refined requirements lead to successful software projects. Vague and incorrect requirements possibly will result in the defective software project. For successful software development, it is vital to recognize precise and accurate requirements for the software project. The progression of information technology has presented various requirements elicitation techniques and therefore analysts are provided with various likely options. Generally, the analyst selects elicitation technique according to company practice or their individual knowledge and skills. It is undefined on the selection of best elicitation techniques for certain situations under particular constraints and circumstances. Several guidelines do exist in literature for technique selection but most technique are theoretical rather than practical. In this research paper, deep knowledge of principal elicitation techniques is explained. After that a five facets model is proposed to select elicitation technique in which major aspects are project characteristics, software development process categories, organizational characteristics, stakeholder characteristics and analyst characteristics. We also demonstrate the suitability of the proposed framework via case studies and verified how the model uses relative knowledge of problem domain to select appropriate requirements elicitation technique for the software under construction.

With the rapid growth of web documents on WWW, it is becoming difficult to organize, analyze and present these documents efficiently. Web search engines return many documents to the web user, out of which some are relevant and some irrelevant documents to the topic, for the given query. Web search is usually performed using only features extracted from the web page text. HTML tags with particular meanings have been found to improve the efficiency of the information retrieval System. However, organizing documents in a way that will improve search without additional cost or complexity is still a great challenge. Clustering can play an important role to organize such a large number of documents into several groups. However due to limitations in existing techniques of clustering, scientists have begun using Meta-heuristic algorithms for the clustering problem of documents. In this paper, we presented a document clustering method that uses HTML tags and Meta-heuristic approaches. The hybrid PSO+ACO+K-means algorithm is used for clustering the documents. In the proposed approach, results are analyzed on WEBKB dataset

Innovation research has got a very significant value in modern research. In contemporary galvanized world, supremacy of new innovation strategies has taken over older strategies. Inbound and outbound innovation strategies have moved from resources based closed innovations within the organization to relation based innovations via interaction with outside world of organizations and customers. There have been research on the relationship of these open innovation strategies with organizational performance and innovation performance. But there was a great need of the empirical research on the impacts these strategies make on innovation performance in Malaysian manufacturing industries. As Malaysia is on slide on world innovation index from 31st to 37th in last five years, an alarm for academics, researchers, industry and government. This endeavor meets that objective. After introduction of the main constructs, a detailed literature review is presented. And a research framework is designed on the basis of the literature. AN updated model of innovation is proposed for BOS and innovation performance. This is an empirical study so the hypothesis are formulated. It is a quantitative research study so data was collected from all over the Malaysian manufacturing and services sector to have a detailed view of the industry. Appropriate different statistical tests are applied to display results considering the requirements of industry, academia and other stake holders. In the end results are presented, and the conclusion is provided for the benefits of Malaysian industries and government. Some insights in the future research area are also provided for the researchers.

The two horrible conditions ahead of time than the organizers worldwide are to diminish the stack at the conventional fills and to reduce the continually developing basic spoiling. This test is proposed to discover probably the execution of the DI diesel motor at various loads when fuelled with mixes of palm methyl esters and diesel. The primers have been pushed on a completely utilized diesel motor without changes. Every one of the appraisals were consistent usa of america and outfitted toward dependable pace. The impact of moving weight develop to be assessed the volume that brake warm temperature ability, mass flow rate, brake one of a kind gas use and fumes gas temperature. Exploratory impacts show that at complete weight conditions, the B-20, B-40and B-60 mixes bring 33.23%, 32.81%, 32.39% and 31.ninety seven% higher brake heat usefulness than sole diesel freely. It wound up confirmed that the brake warmth ability of palm biodiesel is higher than that of diesel, and it is a delayed consequence of the oxygenated atom of biodiesel which acknowledges total ingesting of the biodiesel fuel. In addition the mass development rate of biodiesel is evidently superior to anything that of diesel fuel; it is through method for exact capacity of the calorific estimation of biodiesel is a ton parcels less appeared in one another way as far as diesel gas. At the reason for results obtained from this test utilizing palm biodiesel as a fuel is proposed for the utilized as a piece of a diesel motor with diesel mixes.

El vértigo es un frecuente motivo de consulta cuyo origen puede ser periférico o central; causas poco frecuentes de este último son las asas vasculares que afectan el VIII par craneal llevando a acúfenos, pérdida de la audición y mareo. Se presenta una mujer de 47 años de edad, quien consulta por un cuadro de mareo, náuseas, pérdida del tono postural, cefalea y parestesia facial, cuyo examen físico revela signos de vértigo periférico, iniciándose tratamiento con antieméticos, anticinetósicos y vasodilatadores que llevan a empeoramiento del cuadro, por lo que se sospecha de patología a nivel de sistema nervioso central (SNC) que ejerce compresión con la vasodilatación. Se realiza una resonancia magnética que muestra un asa vascular en la arteria cerebelosa inferior anterior (AICA) que ingresa al conducto auditivo interno (CAI) explicando la sintomatología y cuyo efecto compresivo de los nervios centrales genera un efecto paradójico con la toma de vasodilatadores
