Investigation of symptoms of hand skin changes with aging in Korean women and development of a new standard grading scale for hand aging.

Background: Skin aging, particularly facial skin, has been actively studied. However, hand skin research is limited.

Methods: Aging symptoms of 100 hands of Korean women aged from 20s to 60s were measured by noninvasive and bioengineering methods.

Analysis of the temporal change in biophysical parameters after fractional laser treatments using reflectance confocal microscopy.

Background: Fractional photothermolysis is a popular treatment option for photorejuvenation. Previous literature studies have demonstrated the clinical effectiveness of fractional photothermolysis on cutaneous photoaging; however, the associated changes in biophysical properties of the skin following fractional photothermolysis have not been fully elucidated. This study was conducted to investigate the temporal changes in biophysical parameters after fractional laser treatment on Asian skin.

Neuroprotection by methanol extract of Uncaria rhynchophylla against global cerebral ischemia in rats.

In traditional Oriental medicine, Uncaria rhynchophylla has been used to lower blood pressure and to relieve various neurological symptoms. However, scientific evidence related to its effectiveness or precise modes of action has not been available. Thus, in the current study, we evaluated neuroprotective effects of U.
