c-Jun-mediated miR-19b expression induces endothelial barrier dysfunction in an in vitro model of hemorrhagic shock

open access: yesMolecular Medicine, 2022
Background Our previous data demonstrated that miR-19b expression was increased in human lung microvascular endothelial cells in-vitro-, in-vivo and in patients with hemorrhagic shock, leading to a decrease in syndecan-1 mRNA and protein and resulting in

Quantitative analysis of intermuscular septa in the leg: implications for trauma surgery

open access: yesTrauma Surgery & Acute Care Open, 2021
Background Compartment syndrome is the excess swelling within an inelastic compartment leading to excessive compartment pressure. Lower limb trauma has a high risk of compartment syndrome, which is typically mitigated using a two-incision fasciotomy. Our

Flow visualisation of a normal shock impinging over a rounded contour bump in a Mach 1.3 free-stream [PDF]

open access: yes, 2016
An experimental study has been conducted to visualise the instantaneous streamwise and spanwise flow patterns of a normal shock wave impinging over a rounded contour bump in a Mach 1.3 free-stream.

Extended resuscitative endovascular balloon occlusion of the aorta (REBOA)-induced type 2 myocardial ischemia: a time-dependent penalty

open access: yesTrauma Surgery & Acute Care Open, 2019
Background Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) increases cardiac-afterload and is used for patients in hemorrhagic shock. The cardiac tolerance of prolonged afterload augmentation in this context is unknown.

Nonlinear isolation performance of 6 × 19 wire rope of different lengths under compression

open access: yesAdvances in Mechanical Engineering, 2021
Stainless steel wire rope isolator is widely used in engineering. To optimize design of the isolator, loading, and unloading characteristics of the 6 × 19 6 mm wire rope under compression are investigated. Ropes of different lengths are tested to get the

Shock wave focusing using geometrical shock dynamics [PDF]

open access: yes, 1997
A finite-difference numerical method for geometrical shock dynamics has been developed based on the analogy between the nonlinear ray equations and the supersonic potential equation.
