Twelve patients with previous mitral valve prosthesis underwent transcatheter aortic valve replacement for severe symptomatic aortic valve stenosis and/or aortic valve regurgitation. All patients underwent evaluation with an echocardiogram, computed tomography and coronary angiogram. After the index intervention and be... |
RESULTS |
Eleven patients underwent transcatheter aortic valve replacement for severe symptomatic aortic valve stenosis and one patient for severe aortic valve regurgitation. There was immediate improvement of patients' hemodynamic status; no cases of procedural death, stroke, myocardial infarction, or urgent cardiac surgery occ... |
CONCLUSION |
The current study demonstrates that in patients with severe aortic valve stenosis or regurgitation and mitral valve prosthesis, the implantation of a self-expanding aortic valve via the transfemoral route is safe and feasible, with maintained long-term results.Stories from the South: A Question of Logic |
In this paper, I argue that stories about difference do not promote critical self and social understanding; rather, on the contrary, it is the way we understand ourselves that makes some stories relevantly different. I discuss the uncritical reception of a story about homosexuality in Cuba, urging attention to generali... |

OBJECTIVE |
Previous research has shown a significant relationship between alcohol consumption in the first year following alcohol treatment admission and longer term functioning. This finding is clinically important and pertains to the clinical course of alcohol-use disorders(AUDs). This study investigated mediators of these rela... |
METHOD |
Analyses were conducted on the outpatient Project MATCH (Matching Alcohol Treatment to Client Heterogeneity) sample at baseline (N=952) and at Months 37-39 after treatment admission (n=802; hereafter referred to as 3 years). Participants were classified as first-year "abstainer," "moderate drinker," or "heavy drinker."... |
RESULTS |
Model tests by use of structural equation modeling methods showed poor model fit, owing primarily to problems involving the psychosocial-functioning variable. Consequently, a reduced model was tested that dropped the psychosocial factor. Initial tests of this model showed an excellent fit to the data that replicated ac... |
CONCLUSIONS |
First-year posttreatment admission alcohol use predicts longer term (3-year) alcohol use, and a substantial portion of this relationship seems to be mediated through self-efficacy at 15 months to abstain from alcohol use. The apparent benefit of sustained abstinence in the first year may be in part the result of facili... |
OBJECTIVE |
To develop a novel thermal treatment modality against metastatic tumor, and to verify the hypothesis that the extent of tumor angiogenesis damage and tumor cell necrosis, accompanied with immune suppression cells relief is deterministic to enhance therapeutic effect in the thermal treatment. |
METHODS |
The thermal treatment system was developed in our laboratory. The treatment including hyperthermia and alternate treatment, were locally applied to 4T1 murine mammary carcinoma. The extent of tumor necrosis was examined. Further investigations were performed to study the changes of MDSCs in peripheral blood and spleen. |
RESULTS |
The alternate treatment caused more damage to tumor microvasculature and tumor cell necrosis. Immunosuppression cells significantly reduced in peripheral blood and spleen. Moreover, it highly increased the survival rate of tumor-bearing mice. |
CONCLUSIONS |
The greatest destruction of primary tumor induced by the alternate treatment led to a relief of immune suppression in tumor bearing mice, and significantly increased therapeutic effect, especially for metastatic tumor.Nonrigid Image Registration for Low-Altitude SUAV Images With Large Viewpoint Changes |
Low-altitude aerial photography using small unmanned aerial vehicles (SUAVs) with large viewpoint changes causes nonrigid distortions and low overlap ratios. We present a nonrigid feature-based low-altitude SUAV image-registration method. The key idea of our method is to maintain a high matching ratio on inliers while ... |
This foreword to the Black Lives Matter special issue looks to embrace active listening and open dialogue via writing, and it calls attention to the confines of traditional publishing that otherwise do not support dialogue in writing. Building upon Onwuegbuzie’s (2021) Framework for Promoting Anti-Racism in America, th... |
Control/observation points have been used to detect undetectable faults in delay-insensitive/speed-independent circuits but no techniques exist so far for its use in reducing the test length. The major difficulty is in deriving a safe hazard-free test. A theory for control point insertion is presented for the purpose o... |
A microemulsion for the cutaneous release of quercetin was prepared. An aqueous phase, containing 40% Transcutol® P as solubilizing agent and permeation enhancer, was emulsified with Labrafil® as oil phase and Labrasol®/Capryol™ 90 as Solvent/Co-solvent. Quercetin was dissolved in the microemulsion at the concentration... |
Several 6-aryl-5-oxygenated substituted pyridazinones have been synthesized and evaluated in vitro for inhibition of platelet aggregation induced by adenosine 5'-diphosphate (ADP), thrombin and collagen. All the tested compounds (except 8 and 9) inhibited platelet aggregation in a dose-dependent manner. The IC50 of the... |
This study modeled spite sensitivity (the worry that others are willing to incur a loss to hurt you), which is thought to undergird suspiciousness and persecutory ideation. Two samples performed a parametric, non-iterative trust game known as the Minnesota Trust Game (MTG). The MTG is designed to distinguish suspicious... |
Objective To investigate whether sphericity volume index (SVI), an indicator of left ventricular (LV) remodelling, predicts incident cardiovascular events (coronary heart disease, CHD; all cardiovascular disease, CVD; heart failure, HF; atrial fibrillation, AF) over 10 years of follow-up in a multiethnic population (Mu... |
We present theoretical and experimental evidence for a new type of multimode instability in a homogeneously broadened ring-laser system. The unstable behavior discussed in this paper is the result of multimode competition and can manifest itself either through self-pulsing or hysteretic behavior of the bistable type in... |
We consider the problem of localizing a radio emitter in a wireless network using RSS measured by a set of known network nodes in a multipath environment. While the RSS of a wireless signal can be conveniently accessed, using it to estimate location is nontrivial in the presence of multipath. We propose a HMM model wit... |
The initial use of a service‐oriented system, which collates information from three databases, highlighted a performance problem with query response time for queries that selected more than ten attributes from a single data source. Our aim was to find the cause of the performance problem within the service‐oriented sys... |
This paper reports an investigation into the transport of sensor-generated still images over, ad-hoc, energy- limited networks. MIMO technology was considered as a means of increasing the data rate over network links and thereby the image throughput of the network as a whole. The combining effect of MIMO block size, pa... |

Case-based reasoning (CBR) is based on the use of past experience in finding the solution to a new but similar problem. CBR is composed of five main phases: input of the new problem, retrieval of the most similar cases from the knowledge base, adaptation of retrieved cases, validation of the new solution, and learning ... |
UNLABELLED |
This study, intended to contribute to the fight against HIV/AIDS infection, sought to identify the factors limiting condom use among the pupils of the El Mina middle school in Nouakchott, in the Islamic Republic of Mauritania. |
METHOD |
This investigation, conducted in May 2004, concerned 711 students aged approximately 12-16 years. The dependent variable was condom use, and two categories of independent study variables were examined: socio-demographic and HIV information. The data were entered, verified, and analyzed with Epi info 6.04 software. |
RESULTS |
Overall 40% of the students reported sexual activity; in this group, 41% reported multiple partners and 38% unprotected sexual relations. Condom use was significantly more frequent among boys, married students, students with more than one partner, those who attended educational sessions, those for whom sexuality is a t... |
DISCUSSION |
Condom use among sexually active students is insufficient. This underuse is caused by shortcomings in the distribution system and contributes to the multiplication of sexually-transmitted diseases, including HIV, among the pupils. To provide students with the knowledge necessary for the desired behavioral changes, the ... |
CONCLUSION |
Given the seriousness and the increasing extension of the HIV infection, condom use should be promoted to improve the sexual and reproductive health of students and thus of the entire population of Mauritania.The IGWM Method for Tabriz Traffic Modeling: Data-Oriented Approach |
