Endothelial-specific knockout of the scramblase TMEM16F impairs in vivo clot formation.
Shock
January 2025
Pharmacology, University of Vermont, Burlington, VT.
Objective: Loss of function of the phospholipid scramblase (PLS) TMEM16F results in Scott Syndrome, a hereditary bleeding disorder generally attributed to intrinsic platelet dysfunction. The role of TMEM16F in endothelial cells, however, is not well understood. We sought to test the hypothesis that endothelial TMEM16F contributes to hemostasis by measuring bleeding time and venous clotting in endothelial-specific knockout (ECKO) mice.

: The utilization of intra-aortic balloon pump (IABP) and Impella has been suggested as means of left ventricular unloading in veno-arterial extracorporeal membrane oxygenation (VA-ECMO) patients. This study aimed to assess the local hemodynamic alterations in VA-ECMO patients through simulation analyses. : In this study, a 0D-3D multiscale model was developed, wherein resistance conditions were employed to define the flow-pressure relationship.

Objective: To identify markers associated with pressure injury (PrI) history in individuals with spinal cord injury (SCI) using two approaches: skin blood flow (SBF) response toward localized heating, and serum marker for insulin resistance.
Methods: For this cross-sectional, observational study of adults with chronic traumatic SCI at T12 and above, researchers recruited two groups of participants: with history of PrI (group 1), and without history of PrI (group 2). The study protocol included obtaining fasting blood samples and measurement of SBF at bilateral heels with localized heating of 42 °C for 30 minutes from all participants.

Purpose: Early detection and management of hypertensive disorders during pregnancy and postpartum are essential. This systematic review and meta analysis aimed: (1) to examine the state of 24-hour ambulatory blood pressure (ABP) use, and (2) in a subset of studies, evaluate 24-hour ABP parameters in the prediction and identification of Hypertensive Disorders of Pregnancy (HDP).
Methods: A comprehensive literature search was conducted in March of 2022 for English language studies published after 2000.
Impact of exercise with blood flow restriction on muscle hypertrophy and performance outcomes in men and women.
PLoS One
January 2025
Cardiometabolic, Exercise, and Lifestyle Laboratory, University of New Brunswick, Fredericton, NB, Canada.
Blood flow restriction training (BFRT) has been previously studied as an alternative form of resistance training to gain lean mass and improve performance outcomes. However, in all exercise studies of BFRT, the proportion of female participants represents only 17-29% of all research participants. This highlights a strong underrepresentation of females and the need for more knowledge on the impact of BFRT and sex differences.
