Multi-microjoule broadband terahertz generation in the organic crystal BNA pumped by ytterbium laser pulses compressed via a gas-filled hollow-core fiber.

We investigate the enhanced terahertz generation in the organic crystal BNA when pumped by compressed high-energy ytterbium laser pulses. By compressing the pump pulses from 170 fs down to 43 fs using an argon-filled hollow-core fiber and chirped mirrors, the terahertz conversion efficiency is increased by 2.4 times, leading to the generation of multi-microjoule terahertz pulses with a frequency spectrum almost twice as wide, extending up to 19 THz.

Elevated Septal Native T1 Time in CMR Imaging Suggesting Myocardial Fibrosis in Young Kidney Transplant Recipients.

Background: Patients after kidney transplantation (KTx) in childhood show a high prevalence of cardiac complications, but the underlying mechanism is still poorly understood. In adults, myocardial fibrosis detected in cardiac magnetic resonance (CMR) imaging is already an established risk factor. Data for children after KTx are not available.

Clinical improvements after endoscopic lung volume reduction with valves in patients with advanced emphysema and a 6-min walk test ≤140 m at baseline.

Background: Data regarding the effectiveness and safety of endoscopic lung volume reduction with valves (ELVR) in emphysema patients with a very low 6-min walk test (6MWT) are limited. Patients with severe emphysema and very low exercise capacity, as indicated by a 6MWT ≤140 m, are often excluded from clinical studies on ELVR, assuming limited therapeutic benefits and increased complication risk.

Study Designs And Methods: This study utilised data from the Lungenemphysemregister e.

Safety and efficacy of a light antithrombotic regimen after left atrial appendage occlusion: Insights from the LOGIC (left atrial appendage occlusion in patients with gastrointestinal or IntraCranial bleeding) international multicenter registry.

Background: Antithrombotic therapy (AT) after left atrial appendage occlusion (LAAO) in patients with non-valvular atrial fibrillation (NVAF) has the purpose of preventing device related thrombosis (DRT), avoiding embolic events; nevertheless, the correct antithrombotic regimen after LAAO is still under debate.

Aims: Aim of this substudy of the observational LOGIC registry was to describe the efficacy and safety of a light antithrombotic regimen, comprising single antiplatelet therapy or none, compared to a standard antithrombotic regimen, after a successful LAAO.

Methods: Patients with NVAF that underwent LAAO were previously included in the LOGIC registry.

First Detection of in Namibian Bird Ectoparasites (Acariformes: Syringophilidae) with a Description of New Quill Mite Species.

is a common intracellular bacterial genus that infects numerous arthropods and filarial nematodes. In arthropods, it typically acts as a reproductive parasite, leading to various phenotypic effects such as cytoplasmic incompatibility, parthenogenesis, feminization, or male-killing. Quill mites (Acariformes: Syringophilidae) are a group of bird parasites that have recently attracted increasing interest due to the detection of unique phylogenetic lineages of endosymbiotic bacteria and potentially pathogenic taxa.
