BACKGROUND: Conventional mitral valve (MV) operations allow direct anatomic assessment and repair on an arrested heart, but require cardiopulmonary bypass, aortic cross-clamping, sternotomy or thoracotomy, and cardioplegic cardiac arrest, and are associated with significant perioperative disability, and risks of morbidity and mortality. OBJECTIVES: This study evaluated safety and performance of a transesophageal echocardiographic-guided device designed to implant artificial expanded polytetrafluoroethylene (ePTFE) cords on mitral leaflets in the beating heart...

BACKGROUND: Stress echocardiography (SE) is widely used in Europe. No collective data have been available on the use of SE in Poland until now. AIM: To evaluate the number of SE investigations performed in Poland, their settings, complications, and results. METHODS: In this retrospective survey, referral cardiology centres in Poland were asked to fill in a questionnaire regarding SE examinations performed from May 1, 2014 to May 1, 2015. RESULTS: The study included data from 17 university hospitals and large community hospitals, which performed 4611 SE exa-minations, including 4408 tests in patients investigated for coronary artery disease (CAD) and 203 tests to evaluate valvular heart disease (VHD)...

DNA methylation loss can produce inheritable active epialleles in plants. The mechanism involved in the stable transmission of hypomethylated epimuations is presently not clear. Here we show that maintenance of a stably hypomethylated active epiallele in rice required a CHD3 protein (CHR729) and that over-expression of an H3K4me3 demethylase (JMJ703) or H3K27me3 methyltransferase (SDG711) could stably resilence the epiallele. CHR729 and JMJ703 have antagonistic function in H3K4me3 in maintaining the active state of the epiallele, whereas SDG711-mediated H3K27me3 was sufficient to stably repress the locus...

INTRODUCTION: Treatment with fixed orthodontic appliances requires the application of adhesive systems to enable secure fastening of brackets and retainers to the surface of tooth enamel. The orthodontic bonding systems are similar in terms of chemical composition to dental filling materials, the chemical stability of which is not satisfactory. Particularly alarming is the release of bisphenol A and its derivatives to the external environment, which has been well-documented for materials used in conservative dentistry...

There is a burgeoning literature on first-episode psychosis, the focus of which is early intervention. Little emphasis has been placed on the responses of young people to their experiences of psychosis. This study, therefore, aimed to describe and explain the responses of young people to their first episode of psychosis. Data obtained from ten young people who attended a community early intervention recovery program in Perth Western Australia were analysed using a grounded theory method. The results revealed that the basic psychosocial problem experienced by participants was loss of control resulting in disrupted lives and that the core variable, harnessing resilience, accounted for most of the variance in their behaviour to overcome this problem...

Chronic non-communicable diseases such as heart disease, cancer and diabetes are the biggest killers worldwide. Chronic conditions include heart disease, stroke, diabetes, cancer, chronic respiratory disease and are often comorbid with mental illness. Over 60 years ago, the British Medical Journal reported an association between mental illness and poor physical health (Philips, 1934). Comorbid mental illness and physical illness incrementally worsens health compared with mental illness alone or any of the chronic non-communicable diseases such as cardiovascular diseases, cancers, chronic respiratory diseases and diabetes alone...

We show that all macroscopic quantum superpositions (MQS) based on phase-covariant quantum cloning are characterized by an anomalous high resilence to the decoherence processes. The analysis supports the results of recent MQS experiments and leads to conceive a useful conjecture regarding the realization of complex decoherence-free structures for quantum information, such as the quantum computer.

The different coping responses to three types of aversive events - future threats, acute events and chronic stress - may be modulated by 5HT projections. Dysfunction in these coping mechanisms could cause, respectively: generalised anxiety disorder, panic, and depression. This theory proposes that dorsal raphe nucleus projections to 5HT(2) and 5HT(1D) receptors mediate anticipatory anxiety and normally motivate avoidance of threats. The brain aversion system may be held in check by dorsal raphe nucleus 5HT projections to mediate behavioural inhibition during anticipatory anxiety...

OBJECTIVE: I review and critique basic ideas of both traditional error/risk analysis and the newer and contrasting paradigm of resilience engineering. BACKGROUND: Analysis of human error has matured and been applied over the past 50 years by human factors engineers, whereas the resilience engineering paradigm is relatively new. METHOD: Fundamental ideas and examples of human factors applications of each approach are presented and contrasted...

The purpose of this study was to evaluate the clinical outcomes of root canal treatment in private practice and filled with Resilon. Immediate postoperative radiographs were compared to follow-up radiographs of at least 1 year in 82 randomly selected primary endodontic cases treated according to a nonstandardized protocol but root-filled with Resilon. The Periapical Index (PAI) and the Clinical Impression of Healing (CIH) quantification procedures were used to determine the status and change in the condition of the teeth...

BACKGROUND: Quality of life is dynamic, fluctuating and resilent; it has both positive and negative attributes and is influenced by personal and social expectations. However, it is difficult to measure the experience in a way that is clinically relevant and useful. METHODS: The author examined the literature relating to the assessment and measurement of quality of life as influenced by oral health. RESULTS: It is difficult to interpret the clinical relevance of measurements from questionnaires or structured interviews that use predetermined response options to indicate health-related quality of life...

The study on the effects of long-term suboptimal temperature (T1) and short-term low temperature (T2) under low light density on cucumber seedling's growth and its photosynthesis showed that the growth speed, photosynthetic rate (Pn), carboxylation efficiency (CE), apparent quantum yield (AQY) and actual quantum yield of P(S II) electron transport (phi(PS II)) all declined remarkably, and the photochemical efficiency of PS II (Fnu/Fm) also decreased to some extent. The decreasing extents of Pn, CE and AQY of T1 were less than those of T2, while the recovery rate of T1 was slower than that of T2...

We hypothesized that one mechanical insult could affect cellular proliferation, matrix turnover, and the structural integrity of cartilage, and that these effects would be dose dependent and time dependent. One impact load of low impact (14.4 MPa +/- 2.1 MPa), medium impact (22.8 MPa +/- 5.8 MPa), or high impact (55.5 MPa +/- 12.6 MPa) was administered to the posterior aspect of the medial femoral condyle of New Zealand White rabbits using a previously validated pendulum device. Animals were euthanized at 2, 6, and 12 weeks after impact, and the impacted and sham (contralateral limb) cartilage were harvested...

Starch graft poly(methyl acrylate) (S-g-PMA) was prepared by ceric ion initiation of methyl acrylate in an aqueous corn starch slurry (prime starch) which maximized the accessibility of the starch for graft polymerization. A new ceric ion reaction sequence was established as starch-initiator-methyl acrylate followed by addition of a small amount of ceric ion solution when the graft polymerization was almost complete to quench the reaction. As a result of this improved procedure, no unreacted methyl acrylate monomer remained, and thus, essentially no ungrafted poly(methyl acrylate) homopolymer was formed in the final grafted product...

A traditional approach for examining brain-behavior relations has been the lesion method. This method assumes a direct correspondence between the cognitive process compromised and the site of lesion. Historically, studies with adults have used this framework to map brain functions. In contrast, studies of children with early injury have addressed quite different issues. Developmental animal lesion studies and pediatric neuropsychology studies have focused on the level of plasticity exhibited following early injury...

A study of chief executives identified the ability to prioritize, clear vision, resilence, and willingness to take decisions as key factors in success. Some wanted more active involvement from the regional director. Chief executives could be subject to 360-degree assessment. More work is needed to establish the compatibility of chief executives and chairs.

This study examines the impact of group identification and social context on willingness to participate in industrial protest. Trade union members (N = 313) completed a survey indicating their willingness to participate in union activities, their perceptions of the union and its role, and their attitudes toward present and former governments. Three independent conditions defined the union and its activities in different ways: either (a) referring to conflict with the present government, (b) referring to this conflict together with the government's threat to the union, or (c) presenting no additional information (a control condition)...
