Effects of Ag Nanoparticles on Growth and Fat Body Proteins in Silkworms (Bombyx mori)

Ag nanoparticles (AgNPs), a widely used non-antibiotic, antibacterial material, have shown toxic and other potentially harmful effects in mammals. However, the deleterious effects of AgNPs on insects are still unknown. Here, we studied the effects of AgNPs on the model invertebrate organism Bombyx mori. After feeding silkworm larvae different concentrations of AgNPs, we evaluated ...

Does concomitant tricuspid annuloplasty increase perioperative mortality and morbidity when correcting left-sided valve disease?

A best evidence topic in adult valvular surgery was written according to a structured protocol. The question addressed was ‘Does concomitant tricuspid annuloplasty increase the perioperative mortality and morbidity when correcting left-sided valve disease?’ A total of 561 papers were found using the reported search, of which 12 presented the best evidence to answer the clinical ...

MicroRNA profiling in the left atrium in patients with non-valvular paroxysmal atrial fibrillation

Background We aimed to identify the miRNA expression profiles in left atrial appendage, with the intention of identifying miRNAs that were significantly associated with non-valvular paroxysmal AF. Methods The RNA samples were isolated from healthy controls (n = 5) and patients with atrial fibrillation (n = 8). To confirm the findings obtained by analyzing the miRNA profile, we ...

Is a rigid tricuspid annuloplasty ring superior to a flexible band when correcting secondary tricuspid regurgitation?

Preoperative risk factors of medium-term mitral valve repair outcome

OBJECTIVES This study aimed to evaluate risk factors that affect mitral valve (MV) repair outcomes.

Outcome of Veno-Arterial Extracorporeal Membrane Oxygenation for Patients Undergoing Valvular Surgery

Background We evaluated retrospectively the early and midterm results of using veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support in patients undergoing valvular surgery. Methods A total of 87 patients undergoing valvular surgery received VA-ECMO due to refractory postcardiotomy cardiogenic shock (PCS), who were eligible for inclusion were enrolled in this study. ...

Long-Term Results of a Minimally Invasive Surgical Pulmonary Vein Isolation and Ganglionic Plexi Ablation for Atrial Fibrillation

Background Ganglionated plexi (GP) ablation has been become an adjunct to pulmonary vein isolation (PVI). This study describes the long-term results of minimally invasive surgical PVI, ablation of GPs, and exclusion of the left atrial appendage for atrial fibrillation (AF). Methods Long-term follow-up of 55 months was performed in 139 consecutive patients (age 58.3±20.8 years) with ...

Minimally Invasive Surgical Versus Catheter Ablation for the Long-Lasting Persistent Atrial Fibrillation

Objective To assess the efficacy of video-assisted minimally invasive surgical vs. catheter ablation for the long-standing persistent AF. Methods We performed a retrospective comparative analysis in a series of 166 long-standing persistent AF patients treated between 2006 and 2009 with either video-assisted minimally invasive ablation (83 patients), or catheter ablations (83 ...

Multiple impacts of the plant growth-promoting rhizobacterium Variovorax paradoxus 5C-2 on nutrient and ABA relations of Pisum sativum

Resolving the physiological mechanisms by which rhizobacteria enhance plant growth is difficult, since many such bacteria contain multiple plant growth-promoting properties. To understand further how the 1-aminocyclopropane-1-carboxylate (ACC) deaminase (ACCd)-containing rhizobacterium Variovorax paradoxus 5C-2 affects plant growth, the flows and partitioning of mineral nutrients ...
