The effect of the pericardial patching exclusion technique for left atrial appendage closure on postoperative reopening rate [PDF]

open access: yesBMC Cardiovascular Disorders
Background The left atrial appendage (LAA) is the primary source of cardiogenic embolism in atrial fibrillation patients. Traditional LAA closure methods have shown suboptimal clinical outcomes.

Epiploic appendagitis

open access: yesThe Lancet, 2009
A 25-year-old female presented to the emergency department (ED) with a 1-day history of crampy left iliac fossa (LIF) abdominal pain. It was associated with both nausea and vomiting. On examination she was tender in the LIF with some guarding. Her observations were satisfactory and she was apyrexial.

Left atrial appendage exclusion in atrial fibrillation

open access: yesFrontiers in Cardiovascular Medicine, 2022
Although oral anticoagulants (OACs) are first-line therapy for stroke prevention in patients with atrial fibrillation (AF), some patients cannot be treated with OACs due to absolute or relative contraindications.

Genetic, epigenetic, and post‐transcriptional basis of divergent tissue regenerative capacities among vertebrates

open access: yesAdvanced Genetics, 2021
Regeneration is widespread across the animal kingdom but varies vastly across phylogeny and even ontogeny. Adult mammalian regeneration in most organs and appendages is limited, while vertebrates such as zebrafish and salamanders are able to regenerate ...

Self-Control of Inflammation during Tail Regeneration of Lizards

open access: yesJournal of Developmental Biology, 2021
Lizards can spontaneously regenerate their lost tail without evoking excessive inflammation at the damaged site. In contrast, tissue/organ injury of its mammalian counterparts results in wound healing with a formation of a fibrotic scar due to ...

Toward Robotic Sensing and Swimming in Granular Environments using Underactuated Appendages

open access: yesAdvanced Intelligent Systems, 2023
Granular environments, such as sand, are one of the most challenging substrates for robots to move within due to large depth‐dependent forces, unpredictable fluid/solid resistance forces, and limited sensing capabilities. An untethered robot is presented,

Piton: Investigating the Controllability of a Wearable Telexistence Robot

open access: yesSensors, 2022
The COVID-19 pandemic impacted collaborative activities, travel, and physical contact, increasing the demand for real-time interactions with remote environments. However, the existing remote communication solutions provide limited interactions and do not
