Multiple, Bilateral Renal Oncocytomas: An Uncommon Condition Managed with Percutaneous Cryoablation

The Arab Journal of Interventional Radiology, 2019
Multiple, bilateral renal oncocytomas are uncommon, and the management of this condition is poorly described. Here, we report a case of multiple, bilateral, biopsy-proven renal oncocytomas that were successfully managed using percutaneous cryoablation ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

Population Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Network topology drives population temporal variability in experimental habitat networks

Population Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Cryoballoon ablation for atrial fibrillation in South Africa: One-year outcome from the Cryo Global Registry

South African Medical Journal
Background. Pulmonary vein isolation (PVI) with cryoballoon catheter ablation (CBA) is a well-established and widely adopted method for the treatment of patients with atrial fibrillation (AF) to prevent recurrences of AF.

Atrioventricular Node Ablation to Enhance Resynchronization Therapy Response in a Patient With Complete Atrioventricular Block

JACC: Case Reports, 2021
Up to one-third of patients who undergo cardiac resynchronization therapy do not obtain clinical benefit. A systematic approach can identify treatable causes in many nonresponding patients.

Geographic variation in walking activity in the red flour beetle Tribolium castaneum

Population Ecology, EarlyView.
This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.

Plug-in circuit board for the Raspberry-Pi microcomputer to reproduce multi-channel original electrocardiograms

Current Directions in Biomedical Engineering, 2019
Commercial simulators can only reproduce electrocardiograms (ECG) of the normal and diseased heart rhythm in a simplified waveform and with a low number of channels.

Bilateral thyroid adenomas in an alpaca

Journal of Veterinary Internal Medicine, 2021
A 7‐year‐old neutered male alpaca (Vicugna pacos) was presented for evaluation of a 3‐year history of large, bilateral, firm ventral cervical masses causing esophageal and tracheal impingement.

Classification of Fibrillation Organisation Using Electrocardiograms to Guide Mechanism-Directed Treatments

Frontiers in Physiology, 2021
Background: Atrial fibrillation (AF) and ventricular fibrillation (VF) are complex heart rhythm disorders and may be sustained by distinct electrophysiological mechanisms. Disorganised self-perpetuating multiple-wavelets and organised rotational drivers (
