Background: Near-infrared fluorescence (NIF)-mapping with indocyanine green dye (ICG) facilitates the identification of the intersegmental plane during minimally invasive segmentectomy. Our pilot study showed that ICG is associated with an increase in oncological margin distance from the tumour, greater than the surgeon's best judgment. We hypothesized that, with greater experience, the surgeon's judgement will improve, and the benefit of ICG will diminish.

Exosite crosstalk in thrombin.

J Thromb Haemost

January 2025

Department of Medicine, McMaster University; Department of Biochemistry and Biomedical Sciences, McMaster University; Thrombosis and Atherosclerosis Research Institute, McMaster University and Hamilton Health Sciences.

Thrombin is the central mediator of hemostasis, where it converts fibrinogen to fibrin, activates upstream factors to promote coagulation, activates factor XIII and thrombin-activatable fibrinolysis inhibitor to stabilize fibrin, mediates anticoagulation, and modulates cellular activity via cell surface receptors. Thus, regulation of thrombin activity is essential to the hemostatic balance. Thrombin is regulated by positively charged surface domains that surround the active site.

Background: There is debate as to whether kinematic TKA or mechanical alignment TKA is superior. Recent systematic reviews have suggested that kinematically aligned TKAs may be the preferred option. However, the observed differences in alignment favoring kinematic alignment may not improve outcomes (performance or durability) in ways that patients can perceive, and likewise, statistical differences in outcome scores sometimes observed in clinical trials may be too small for patients to notice.

Blink-related oscillations (BROs) are newly discovered neurophysiological brainwave responses associated with spontaneous blinking, and represent environmental monitoring and awareness processes as the brain evaluates new visual information appearing after eye re-opening. BRO responses have been demonstrated in healthy young adults across multiple task states and are modulated by both task and environmental factors, but little is known about this phenomenon in aging. To address this, we undertook the first large-scale evaluation of BRO responses in healthy aging using the Cambridge Centre for Aging and Neuroscience (Cam-CAN) repository, which contains magnetoencephalography (MEG) data from a large sample ( = 457) of healthy adults across a broad age range (18-88) during the performance of a simple target detection task.
