Primary arthrodesis versus open reduction internal fixation for complete Lisfranc fracture dislocations: a retrospective study comparing functional and radiological outcomes.

Background: The aims of this retrospective study were to compare the functional and radiological outcomes of primary arthrodesis and open reduction internal fixation (ORIF) for the treatment of complete Lisfranc fracture dislocations.

Methods: A retrospective cohort study of 39 patients treated for a complete Lisfranc fracture dislocation, defined as Myerson types A and C2, over a period of 8 years at a level 1 trauma centre was performed. Of these, 18 underwent primary arthrodesis, and 21 ORIF.

TRPV3 expression and vasodilator function in isolated uterine radial arteries from non-pregnant and pregnant rats.

This study investigated the expression and function of transient receptor potential vanilloid type-3 ion channels (TRPV3) in uterine radial arteries isolated from non-pregnant and twenty-day pregnant rats. Immunohistochemistry (IHC) suggested TRPV3 is primarily localized to the smooth muscle in arteries from both non-pregnant and pregnant rats. IHC using C' targeted antibody, and qPCR of TRPV3 mRNA, suggested pregnancy increased arterial TRPV3 expression.

Is cardiac magnetic resonance imaging as accurate as echocardiography in the assessment of aortic valve stenosis?

A best evidence topic was written according to a structured protocol. The question addressed was: is cardiac magnetic resonance (CMR) imaging as accurate as echocardiography in the assessment of aortic valve stenosis? Altogether 239 papers were found using the reported search. Only 12 demonstrated the best evidence to answer the clinical question.

Transient receptor potential canonical type 3 channels facilitate endothelium-derived hyperpolarization-mediated resistance artery vasodilator activity.

Aims: Microdomain signalling mechanisms underlie key aspects of artery function and the modulation of intracellular calcium, with transient receptor potential (TRP) channels playing an integral role. This study determines the distribution and role of TRP canonical type 3 (C3) channels in the control of endothelium-derived hyperpolarization (EDH)-mediated vasodilator tone in rat mesenteric artery.

Methods And Results: TRPC3 antibody specificity was verified using rat tissue, human embryonic kidney (HEK)-293 cells stably transfected with mouse TRPC3 cDNA, and TRPC3 knock-out (KO) mouse tissue using western blotting and confocal and ultrastructural immunohistochemistry.
