Video atlas of pulmonary segmentectomy: robotic-assisted right S3 segmentectomy with 3-dimensional imaging.

Robotic-assisted thoracic surgery has become increasingly utilized in recent years. Complex lung cancer resection surgery can be performed using a robotic approach. It facilitates 3-dimentional visualization of structures, enhanced manipulation of tissues and precise movements.

Efficacy of Amitriptyline in Irritable Bowel Syndrome: A Systematic Review and Meta-analysis.

Background/aims: Amitriptyline is prescribed off-label for irritable bowel syndrome (IBS). We conducted a meta-analysis to assess its efficacy.

Methods: A systematic literature review was conducted until November 10, 2023, using MEDLINE, Embase, Cochrane Library, and Web of Science to study the efficacy of amitriptyline in patients with IBS.

Microbial and chemically induced reductive dechlorination of polychlorinated biphenyls in the environment.

Polychlorinated biphenyls (PCBs) are persistent organic pollutants and are emitted during e-waste activities. Once they enter into the environment, PCBs could pose toxic effects to environmental compartments and public health. Reductive dechlorination offers a sustainable solution to manage the PCBs-contaminated environment.

Electrocalcium coupling in brain capillaries: Rapidly traveling electrical signals ignite local calcium signals.

The routing of blood flow throughout the brain vasculature is precisely controlled by mechanisms that serve to maintain a fine balance between local neuronal demands and vascular supply of nutrients. We recently identified two capillary endothelial cell (cEC)-based mechanisms that control cerebral blood flow in vivo: 1) electrical signaling, mediated by extracellular K-dependent activation of strong inward rectifying K (Kir2.1) channels, which are steeply activated by hyperpolarization and thus are capable of cell-to-cell propagation, and 2) calcium (Ca) signaling, which reflects release of Ca via the inositol 1,4,5-trisphosphate receptor (IPR)-a target of G-protein-coupled receptor signaling.
