Comparison of an oblique single cut rotation osteotomy with a novel 3D computer-assisted oblique double cut alignment approach.

Sci Rep 2021 Jul 19;11(1):14731. Epub 2021 Jul 19.

Department of Biomedical Engineering and Physics, Amsterdam Movement Sciences, Amsterdam UMC, University of Amsterdam, Room no L0-113-3, Meibergdreef 9, 1105 AZ, Amsterdam, The Netherlands.

An oblique double-cut rotation osteotomy (ODCRO) enables correcting a complex bone deformation by aligning, in 3D, the distal, middle and proximal bone segments with a target bone, without intersegmental gaps. We propose virtual preoperative planning of an ODCRO. To minimize a residual translation error, we use an optimization algorithm and optimize towards bone length, alignment in the transverse direction, or a balanced reconstruction. Read More

Expression of exogenous epithelial sodium channel beta subunit in the mouse middle cerebral artery increases pressure-induced constriction.

Am J Hypertens 2021 Jun 23. Epub 2021 Jun 23.

Department of Physiology and Biophysics, University of Mississippi Medical Center, Jackson, Mississippi.

Background: Pressure-induced constriction (PIC) is inherent to small arteries and arterioles, in which intraluminal pressure-induced vascular smooth muscle cell (VSMC) stretch elicits vasoconstriction. Degenerin (Deg) proteins, such as beta Epithelial Na + Channel (βENaC), have been studied in the PIC response because they are evolutionarily linked to known mechanosensors. While loss of Deg function phenotypes are plentiful, a gain of function phenotype has not been studied. Read More
