OBJECTIVE This study aimed to evaluate the mean age of menarche, its secular trend in Korean women, and the relationship between malocclusion and the rate of skeletal maturation, as defined by menarcheal age. METHODS We retrospectively collected data on menarcheal age from 931 Korean women born during 1961 - 1997. Subjects were divided by the malocclusion type and birth-year decade into 3 and...

The purpose of this study was to investigate the properties of the flexible pressure sensor under laboratory conditions simulating the internal environment of the total surface bearing (TSB) socket to determine optimal conditions for measuring normal stresses on the stump. The equipment used in the study was the Pressure Distribution Sensor System for Sockets. In a climatic chamber maintained a...

BACKGROUND Tourniquets are used on distal limb segments. We examined calf and forearm use of four thigh-effective, commercial tourniquets with different widths and tightening systems: 3.8 cm windlass Combat Application Tourniquet® (CAT, combattourrniquet.com) and Special Operations Forces® Tactical Tourniquet-Wide (SOFTTW, www.tacmedsolutions.com), 3.8 cm ratchet Ratcheting Medical Tourniquet -...

OBJECTIVE Depth of cure of composite material is restricted and it depends on many parameters such as thickness. The aim of this in-vitro study was to evaluate the depth of cure of two light-cured core build-up composites (Quixfil and Photocore) in different thicknesses, when cured for 60 seconds. MATERIALS AND METHODS The Vickers microhardness measurements were made for each side of the top ...

Shear stress is an important stimulus to arterial adaptation in response to exercise and training in humans. We recently observed significant reverse arterial flow and shear during exercise and different antegrade/retrograde patterns of shear and flow in response to different types of exercise. The purpose of this study was to simultaneously examine flow-mediated dilation, a largely NO-mediated...
