The efficacy of tests of differential item functioning (measurement invariance) has been well established. It is clear that when properly implemented, these tests can successfully identify differentially functioning (DF) items when they exist. However, an assumption of these analyses is that the metric for different groups is linked using anchor ...

  In liver resection, the temporary occlusion of the hepatoduodenal ligament (Pringle maneuver) is often used. However, the maneuver causes ischemia/reperfusion (I/R) injury in the remnant liver. Heme oxygenase (HO)-1 has a cytoprotective role against this injury. Our aim is to investigate whether splenic artery ligation induces HO-1 expression in ...

We report a homoleptic Au-Cu alkynyl cluster that represents an unexplored class of luminescent materials with stimuli-responsive photophysical properties. The bimetallic complex formulated as [Au2Cu2(C2OHC5H8)4]n efficiently self-assembles from Au(SC4H8)Cl, Cu(NCMe)4PF6 and 1-ethynylcyclopentanol in the presence of NEt3. This compound shows remarkably diverse polymorphism arising from the modulation of metallophilic interactions ...
