The success rate of catheter ablation in atrial fibrillation (AF) is known to be lower females than males. However, while the exact mechanism for this phenomenon remains elucidated, tissue fibrosis may play an important role regard. It has been shown that promotes AF and its recurrence, thereby substantially reducing efficacy patients. Thus, we hypothesized contribute gender differences outcomes ablation. Here systematically assessed pulmonary vein sleeves obtained from 166 patients with...

Neurologists judge the severity of Parkinsonian motor symptoms according to clinical scales, and their judgments exist inconsistent because differences in experience. Correspondingly, inertial sensing-based wearable devices (ISWDs) produce objective standardized quantifications. However, ISWDs indirectly quantify by parametric modeling angular velocities linear accelerations nd trained several neurologists through supervised learning algorithms. Hence, ISWD outputs are biased along with...

In a real industrial scenario, domain shift frequently occurred due to working loads variation, operation speeds and environmental noise interference, severely degrading intelligent fault diagnosis models' performance. Currently, adaptation-based models eliminate by calibrating unlabeled target-domain data using labeled source-domain data. Nevertheless, these may fail when encountering unseen conditions, lacking for learning domain-invariant features. Besides, the existing deep lack few-shot...

A highly enantioselective intermolecular [2 + 1] cycloaddition of primary N-vinylamides with carbene intermediates was developed by taking advantage cationic rhodium(I)/diene catalysis under mild conditions at room temperature. This cyclopropanation method facilitates rapid access to enantioenriched cyclopropylamides, an important motif in drug discovery, generally good yields and high stereoselectivities (>20:1 dr, up 99% ee). approach employs a rhodium(I) catalyst form pre-equilibrium...

The optical tracking system (OTS) plays a vital role in the computer-assisted surgical navigation process, whereas performance of commonly used binocular stereo vision is affected by line-of-sight problem and limited workspace. Thus, this article proposed prior knowledge-based multicamera reconstruction model (PKRM) to both expand workspace improve robust computational efficiency OTS when working unstructured clinical conditions. This inherits advantages geometrical method, data-driven...

We retrospectively reported our 26-year experience with operative repair of total anomalous pulmonary venous connection (TAPVC) biventricular physiology.Between December 1982 and 2008, 122 TAPVC patients heart underwent surgical in department. Moderate or deep hypothermia was induced at the time cardiopulmonary bypass (CPB). Follow-up conducted for 5 postoperative years. Surgical outcomes early intermediate deaths after were analyzed.Six occurred operatively; three deaths, during follow-up....

Objective. The quantitative assessment of Parkinsonian tremor, e.g. (0, 1, 2, 3, 4) according to the Movement Disorder Society-Unified Parkinson's Disease Rating Scale, is crucial for treating disease. However, tremor amplitude constantly fluctuates due environmental and psychological effects on patient. In clinical practice, clinicians assess severity a short duration, whereas manual labeling relies clinician's physician experience. Therefore, automatic quantification based wearable...

Objective Early death following coronary artery bypass graft ( CABG ) surgery tends to occur in heart disease CHD patients with significantly decreased left ventricular function. Methods The clinical data of 231 preoperative ejection fraction LVEF ≤35% who underwent were retrospectively analyzed from June 2007 October 2012. divided into 2 groups: group A contained 39 suffered early postoperative and B 192 had a successful outcome. Results Multivariate analysis demonstrated that only right...

Pulsatile pulmonary blood flow plays an important role in regulating shear-stress-mediated release of endothelium-derived nitric oxide and endothelin-1, it reduces vascular resistance by passive capillary recruitment. The aim this study was to demonstrate changes structure endothelial function induced the chronic nonpulsatile Fontan circulation. A canine model with right lung established, sacrificed 3 months later. Compared left lung, wall thickness arterioles thinner, endothelin-1...

Mechanistic details of the aerobic oxidative coupling methyl groups by a novel (MeL)PdII(Me)2 complex with tetradentate ligand, MeL = N,N-dimethyl-2,11-diaza[3.3](2,6)pyridinophane, has been explored density functional theory calculations. The calculated mechanism sheds light on role this ligand's flexibility in several stages reaction, especially as oxidation state Pd changes. Ligand leads to diverse axial coordination modes, and it controls availability electrons modulating energies...

Optical tracking technique based on multiple cameras is widely employed in robots, virtual reality, and industrial measurements due to its excellent position accuracy. However, 6-D practicability impaired by the line-of-sight issue complicated tracker markers. Hence, we implemented a custom-built hybrid system consisting of four-camera equipment comprising single optical marker an automatic heading reference (AHRS). AHRS provides 3-D orientation tracked object directly compensates for when...

<b>Background</b> Though maze III procedure is an effective surgical treatment for atrial fibrillation (AF), the complexity and complications prevent its widespread application. Radiofrequency ablation (RA) has become accepted therapy, but chronic effects are still unclear. This retrospective clinical study describes our experience of RA vagal denervation (VD) in long-standing AF associated with rheumatic heart disease (RHD) during a 5-year follow-up. <b>Methods</b> Between June 2006...

Aims Common atrium (CA) is a rare congenital heart defect. We reviewed our experience of surgical treatment CA and summarize the clinical features key techniques for correction. Methods Between August 1984 2010, 37 consecutive cases underwent corrective surgery. There were no findings Down, asplenia–polysplenia or Ellis–van Creveld syndromes in all cases. Mitral valvuloplasty was performed 34 cases, tricuspid 20 Complete closure mitral cleft required 32 All new atrial septa reconstructed...
