Prediction of Recurrent Atrial Tachyarrhythmia After Receiving Atrial Flutter Ablation in Patients With Prior Cardiac Surgery for Valvular Heart Disease

Background: Surgical scars cause an intra-atrial conduction delay and anatomical obstacles that facilitate the perpetuation of atrial flutter (AFL).This study aimed to investigate the outcome and predictor of recurrent atrial tachyarrhythmia after catheter ablation in patients with prior cardiac surgery for valvular heart disease (VHD) who presente

Exploring the Genetic Variation of Stripe Rust Foliar and Head Infection in Egyptian Wheat as an Effect of Climate Change

Wheat stripe rust (Puccinia striiformis Westend f.sp.tritici; Pst) is a severe disease that affects wheat-growing areas worldwide.In the last few years, Pst head infection (PstHI) was recorded to cause severe yield damage in Egypt.Little information is known about PstHI.In the current study, a set of 34 Egyptian cultivars were evaluated for their P

Open challenges in tensile testing of additively manufactured polymers: A literature survey and a case study in fused filament fabrication

Additive manufacturing (AM, also commonly termed 3D printing) is progressing from being a rapid prototyping tool to serving as pillar of the Industry 4.0 revolution.Thanks to their low density and ease of printing, polymers are receiving increasing interest for the fabrication of structural and lightweight parts.Nonetheless, the lack of appropriate

Developmental and reproductive performance of a specialist herbivore depend on seasonality of, and light conditions experienced by, the host plant.

Host plant phenology (as influenced by seasonality) and light-mediated changes in the phenotypic and phytochemical properties of leaves have been hypothesised to equivocally influence insect herbivore performance.Here, we examined the effects of seasonality, through host plant phenology (late growth-season = autumn vs flowering-season = winter) and
