Influence of repeated cut-off and rescanning on the trueness of the intraoral digital scans.

Objectives: To evaluate the effects of repeated cut-off and rescan procedures on the trueness of three intraoral scanners (IOS).

Methods: A tooth model (#16) with a standard class II cavity was prepared, and the complete-arch was scanned using a laboratory scanner (D2000, 3Shape A/S) to obtain a reference scan. Then the typodont was scanned with three IOSs (3Shape TRIOS 3, CEREC Omnicam, and Medit i500) under two rescanning strategies (full-cut and partial-cut), with varying numbers of repeated cut-off and rescanning procedures (0, 1, 3, 5, 7, or 10).

GPR30 Alleviates Pressure Overload-Induced Myocardial Hypertrophy in Ovariectomized Mice by Regulating Autophagy.

The incidence of heart failure mainly resulting from cardiac hypertrophy and fibrosis increases sharply in post-menopausal women compared with men at the same age, which indicates a cardioprotective role of estrogen. Previous studies in our group have shown that the novel estrogen receptor G Protein Coupled Receptor 30 (GPR30) could attenuate myocardial fibrosis caused by ischemic heart disease. However, the role of GPR30 in myocardial hypertrophy in ovariectomized mice has not been investigated yet.

Intraluminal thrombus attached to the lesser curvature of the aortic arch and cerebral ischemic stroke after its surgical removal.

Some cases of thrombi at the ascending and descending aorta have been reported, but there are only a few reports of intraluminal aortic arch thrombi. Most intraluminal thrombi are associated with atherosclerotic lesions at the aortic wall. Here, we report a case of an intraluminal thrombus attached to the lesser curvature of the aortic arch.
