Sirtuins (SIRTs) are involved in multiple cellular processes. And they are involved in cellular pathways related aging, cancer, and a variety of cellular functions including cell cycle, DNA repair and proliferation. Also they modulate life span. Stem cells have the ability to self-renew for unlimited proliferation and differentiate into various cell types. It has been a little known that the mutation of undifferentiated stem cells in tissue may result in the development of cancer cells by genotoxic carcinogens. Therefore, this study investigated whether some carcinogenic compounds can modulate the expression of sirtuin mRNA on human adipose-derived stem cells. Adipose-derived stem cells (ADSC) were exposed to genotoxic carcinogenic compound (2-nitrofluorene, 2NF) and non-genotoxic carcinogenic compound (clonidine, CND) for 24 hours, 48 hours, 72 hours and 96 hours. The expression of SIRT1 mRNA increased on 72 hours. Expressions of SIRT2 and SIRT7 mRNA increased robustly on 48 hours. But all of SIRTs decreased to a level before a treatment of genotoxic compound on adipose-derived stem cells. These results demonstrated that a treatment of genotoxic compound induced the expression of SIRT mRNA only in the short time. But their level returned to untreated cells on 96 hours. They suggest that the possibility that the sirtuins can retard the carcinogenesis of adipose derived stem cells.

Estimation of biological profile for skeletal remains by forensic anthropological examination would be possible based on physical anthropological studies which were statistically analyzed. However, physical anthropological studies for Korean population are not enough to establish biological profile for Korean because there is lack of documented osteological specimens in Korea. Recent study suggested that physical anthropological examination could be possible on the three dimensional data which were reconstructed from computed tomography, instead of preparing skeletal specimen by defleshing bone. One of the aim of this study is to evaluate Digital Korean database which were composed of computed tomographic images of 100 cadavers. The other is to perform statistical analysis on morphometrics for segmented atlas whether the results could be helpful to estimate sex in Korean. We measured 100 segmentation atlases (male 51, female 49) from the Digital Korean database which were under the control of Catholic Institute for Applied Anatomy, The Catholic University of Korea. Measurements of segmented atlas were carried out by using Mimics software (Simulation module, Version 13.0, Materialise NV, Belgium), and values of measurement were performed statistical analysis by IBM(R) SPSS(R) (version 20.0, Armonk, New York). Among 19 measurements, the width of atlas showed most crucial element for estimating sex, which was consistent with the result using dried bones of atlas and hit ratio of discriminant functions was 88.0%. 76.7 was the cut-off score of discriminant functions. This results showed that morphometrics for segmented atlas could be helpful in estimating sex using the Digital Korean database. In the future, we expect that the other researchers could more actively use the Digital Korean database as a good specimen for physical and forensic anthropological study.

This study aimed to determine the number of branches of the upper and lower subscapular nerves and to classify the spinal nerve compositions of each branch. Twenty sides of the brachial plexus extracted from Korean adult cadavers were used in this study. The upper subscapular nerve was composed of three branches in 16 sides (80.0%), composed of four branches in 4 sides (20.0%). The lower subscapular nerve arose from posterior cord with one branch, innervating the subscapularis and the teres major muscles. In case of the upper subscapular nerve, the first branch was comprised of C5 in 40.0%, C5 and C6 in 60.0%, the second branch was composed of C5 in 15.0%, C5 and C6 in 85.0%, the third branch was arisen from C5 and C6 in 75.0%, C6 in 25.0% and the forth branch appeared in four sided was derived from C6. The nerve branch innervating the subscapularis muscle was composed of C6 in 55.0%, C5 and C6 in 40.0%, C6 and C7 in 5.0%. The nerve branch innervating the teres major muscle was composed of C6 and C7 in 65.0%, C5, C6 and C7 in 25.0%, and C6 in 10.0%. The injury was often due to an accidental damage or lesion of the subscapular nerve, these anatomical results may be helpful to predict the involving area of the lesion.
