Wrinkles in the opening angle method

Mouth opening: a new angle.

BACKGROUND The authors hypothesized that craniocervical extension occurs during normal mouth opening. METHODS Twenty volunteers were studied. Interdental distance was measured at four different degrees of craniocervical extension. RESULTS Interdental distance increased from 28 mm (95% confidence interval, 25-30) in slight flexion to 46 mm (95% confidence interval, 42-49) at full extension. ...

Opening angle of human saphenous vein

In this study, the residual strain was evaluated for human saphenous vein. Rings of the vein from four donors (two male and two female; age 62±5 years) were radially cut to obtain the opening angle (α) of the tissue. It was found that the average opening angle is 45°±18° (mean±SD). Then, the intraluminal distribution of circumferential stress was computed for one donor in order to verify the un...

Magic angle spinning magnetic resonance: a novel method opening up translational research into NAFLD?

NAFLD (non-alcoholic fatty liver disease) and NASH (non-alcoholic steatohepatitis) are of increasing importance, both in connection with insulin resistance and with the development of liver cirrhosis. Histological samples are still the 'gold standard' for diagnosis; however, because of the risks of a liver biopsy, non-invasive methods are needed. MAS (magic angle spinning) is a special type of ...

A New Method for Measuring the Angle of Hallux Valgus

Objectives. The aim of this study is to introduce a new way and assign its reliability and validity in measuring the angle of hallux valgus. Methods. In this method, we have proceeded to introduce a simple way for measuring the angle of hallux valgus by using ruler and mathematical formulas. For doing this study, we selected 25students and measured their angle of hallux valgus with new way ...
