BACKGROUND: For persistent atrial fibrillation (AF) ablation, different strategies including complex fractionated atrial electrograms (CFAE) ablation and linear lesions (LL) have been used in addition to pulmonary vein isolation (PVI). However, it is still a matter of debate if extended substrate modification improves long-term outcome. The aim of this study was to determine the benefit of LL in addition to PVI and CFAE ablation regarding freedom from arrhythmia recurrence in patients with persistent AF...

Sonography is a convenient, non-invasive diagnostic modality in small ruminants, often used in reproductive management, internal medicine, and surgery. Pregnancy diagnostics and imaging anatomy and pathology of organs, such as neoplasia, are major applications. Urolithiasis is one of the most common causes of death in male sheep and goats, for which sonography is the diagnostic modality of choice. Although ultrasound-imaging techniques for kidneys, ureters, and urinary bladder in small ruminants have been described previously, this study focuses on reporting the imaging technique of the extra-pelvic portion of the urethra, as nearly all the cases of obstructive urolithiasis result from urinary stones in this part...

Prospective population based-registers of amyotrophic lateral sclerosis (ALS) have operated in Europe for over two decades, and have provided important insights into our understanding of ALS. Here, we review the benefits that population registers have brought to the understanding of the incidence, prevalence, phenotype and genetics of ALS and outline the core operating principles that underlie these registers and facilitate international collaboration. Going forward, we offer lessons learned from our collective experience of operating population-based ALS registers in Europe for over two decades, focusing on register design, maintenance, identification and management of bias and the value of cross-national harmonisation and integration...

Shunt series (SS) X-rays are often performed as additional routine initial investigations for suspected ventriculo-peritoneal shunt dysfunction, despite low diagnostic utility and radiological implications. We reviewed such referrals at our neurosurgical unit and found an 8.3% sensitivity rate for SS; consistent with current evidence. SS should not be performed routinely.

A convenient synthesis of substituted spiroindenoquinoxalines at mild and green conditions was developed. Multicomponent reaction of substituted phenylene diamines, ninhydrin, malononitrile and N,N'-substituted-2-nitroethene-1,1-diamines produced the target compounds. Twelve new spiroindenoquinoxalines were obtained, and their ability in inhibition of acetyl and butyrylcholinesterases were investigated both in vitro and in silico. All compounds showed moderate level activity against both acetyl and butyrylcholinesterases...

Asian citrus psyllid (Diaphorina citri) feeding behaviors play a significant role in the transmission of the phloem-limited Candidatus Liberibacter asiaticus (CLas) bacterium that causes the economically devastating citrus greening disease. Sustained phloem ingestion by D. citri on CLas infected plants is required for pathogen acquisition and transmission. Recent studies have shown a fibrous ring of thick-walled sclerenchyma around the phloem in mature, fully expanded citrus leaves that is more prominent on the abaxial compared with the adaxial side...

Delirium is characterized by impaired cognition with nonspecific manifestations. In critically ill patients, it may develop secondary to multiple precipitating or predisposing causes. Although it can be a transient and reversible syndrome, its occurrence in Intensive Care Unit (ICU) patients may be associated with long-term cognitive dysfunction. This condition is often under-recognized by treating physicians, leading to inappropriate management. For appropriate management of delirium, early identification and risk factor assessment are key factors...

Maternal hyperhomocysteinemia during pregnancy is associated with increased risk of NTD in the offspring. Our study investigated the effects of homocysteine (Hcy) on proliferation and neuronal differentiation of the spinal cord cells in a chick embryo model. Embryos were treated with 20μmol D-L Hcy/50μL saline solution at embryonic day 2 (E2) and analyzed at embryonic days 4 (E4) and 6 (E6). Control embryos received exclusively 50μL saline solution. We performed immunolocalization and flow cytometry analyses using antibodies anti-phosphohistone H3 (pH3), anti-proliferating cell nuclear antigen (PCNA), anti-β-tubulin III and anti-p53...
