Channels, Transporters, and Receptors at Membrane Contact Sites.

Membrane contact sites (MCSs) are specialized regions where two or more organelle membranes come into close apposition, typically separated by only 10-30 nm, while remaining distinct and unfused. These sites play crucial roles in cellular homeostasis, signaling, and metabolism. This review focuses on ion channels, transporters, and receptors localized to MCSs, with particular emphasis on those associated with the plasma membrane and endoplasmic reticulum (ER).

Multiclass arrhythmia classification using multimodal smartwatch photoplethysmography signals collected in real-life settings.

In the early stages of atrial fibrillation (AF), most cases are paroxysmal (pAF), making identification only possible with continuous and prolonged monitoring. With the advent of wearables, smartwatches equipped with photoplethysmographic (PPG) sensors are an ideal approach for continuous monitoring of pAF. There have been numerous studies demonstrating successful capture of pAF events, especially using deep learning.

The origin and evolution of shrews (Soricidae, Mammalia).

Shrews are among the most speciose of mammalian clades, but their evolutionary history is poorly understood. Their fossil record is fragmentary and even the anatomy of living groups is not well documented. Here, we incorporate the oldest, most complete fossil shrew yet known into the first phylogenetic analysis of the group to include molecular, morphological and temporal data.

Healthy at Home for COPD: An Integrated Digital Monitoring, Treatment, and Pulmonary Rehabilitation Intervention.

Background: Chronic Obstructive Pulmonary Disease (COPD) is a leading cause of morbidity and mortality in the United States. Frequent exacerbations result in higher use of emergency services and hospitalizations, leading to poor patient outcomes and high costs.

Objective: Demonstrate the feasibility of a multimodal, digitally enhanced remote monitoring, treatment, and tele-pulmonary rehabilitation intervention among patients with COPD.

The Surveillance Strategy for Intraductal Pancreatic Mucinous Neoplasms: Criteria for Discontinuation.

Objective: To review the surveillance of IPMN, the risk of pancreatic cancer and the cost of surveillance.

Background: The increasing IPMN prevalence and low pancreatic cancer associated with IPMN question the necessity and cost-effectiveness of surveillance. Guidelines favour a 'watch and wait' approach, lacking clarity on stopping surveillance.
