Background: Video-assisted thoracoscopic surgery (VATS) is recognized as a safe and effective treatment modality for early-stage lung cancer and anterior mediastinal masses. Recently, novel articulating instruments have been developed and introduced to endoscopic surgery. Here, we share our early experiences with VATS major pulmonary resection and thymectomy performed using ArtiSential articulating instruments. Methods: At the Seoul Metropolitan Government-Seoul National University Boramae Medical Center, 500 patients underwent VATS pulmonary resection between July 2020 and April 2023, while 43 patients underwent VATS thymectomy between January 2020 and April 2023. After exclusion, 224 patients were enrolled for VATS major pulmonary resection, and 38 were enrolled for VATS thymectomy. ArtiSential forceps were utilized in 35 of the 224 patients undergoing pulmonary resection and in 12 of the 38 individuals undergoing thymectomy. Early clinical outcomes were retrospectively analyzed. Results: No significant differences were observed in sex, age, surgical approach, operation time, histological diagnosis, or additional procedures between the patients who underwent surgery using novel articulating instruments and the group treated with conventional endoscopic instruments for both VATS major pulmonary resection and thymectomy. However, the use of the novel articulating endoscopic forceps was associated with a significantly larger number of dissected lymph nodes (p=0.028) and lower estimated blood loss (p=0.009) in VATS major pulmonary resection. Conclusion: Major pulmonary resection and thymectomy via VATS using ArtiSential forceps were found to be safe and effective, with early clinical outcomes comparable to established methods. Further research into long-term clinical outcomes and cost-effectiveness is warranted.

Breast cancer is the second leading cause of death in woman. Unfortunately, the frequency of breast cancer and mastectomy are increasing in Korea. This paper introduces the breast reconstruction by use of pectoralis major muscle transfer with breast implant for small size defect after skin sparing mastectomy for more satisfaction. We reviewed 24 consecutive patients who underwent breast reconstruction by pectoralis major muscle transfer with implant and only breast implant in Dong-A University from April 2002 to March 2004. The patient's age ranged between 29 and 54 years with mean of 42.3 years. We used pectorals major muscle transfer with breast implant in 12 patients and breast implant alone in 12 patients as control. The follow-up period of patients ranged from 10 months to 3 years with mean of 18.5 months. The points of comparison with control group reconstructed by breast implant alone were doctor and patient satisfaction score, operation time, duration of admission, amount of drainage, complication and satisfaction according to mass location. In conclusion, there is no difference with control group in the point of operation time, mount of drainage, duration of admission. And there is higher level of doctor's and patient's satisfaction in group reconstructed by pectoralis major muscle transfer with breast implant than implant only group. Especially, pectoralis major muscle transfer with breast implant was especially necessary for the defect in upper lateral quadrant of the breast to get more satisfaction. The advantage of pectoralis major muscle transfer with breast implant is prevention of the protruding and palpability of implant and aesthetically satisfactory result by intraoperative modification of breast shape.

Major depression is a devastating disorder of which lifetime prevalence rate is as high as up to 25% in general population. Although the etiology of the disorder is still poorly understood, it is generally accepted that both genetic and environmental factors are involved in the precipitation of depression. Stressful lifetime events are potent precipitating environmental factors for major depression and early-life stress is in particular an important element that predisposes individuals to major depression later in life. How environmental factors such as stress can make our neural networks susceptible to depression and how those factors leave long-lasting influences have been among the major questions in the field of depression research. Epigenetic regulations can provide a bridging mechanism between environmental factors and genetic factors so that these two factors can additively determine individual predispositions to major depression. Here we introduce epigenetic regulations as candidate mechanisms that mediate the integration of environmental adversaries with genetic predispositions, which may lead to the development of major depression, and summarize basic molecular events that underlie epigenetic regulations as well as experimental evidences that support the active role of epigenetic regulation in major depression.

Objective : To understand the anatomic characteristics of the aortic arch (AA) and its major branches to build a foundation toward performing endovascular surgery safely. Methods : A total of 25 formalin fixed Korean adult cadavers were used. The authors investigated : anatomical variations of the AA and its major branches; curvature of the AA; distance from the mid-vertebrae line to the origin of the major branches; distances from the origin of the major branches of AA to the origin of its distal branches; and the angle of the three major branches, the brachiocephalic trunk (BCT), the left common carotid artery (LCCA) and the left subclavian artery (LSCA) arising from AA. Results : The three major branches directly originated from AA in 21 (84%) of the cadavers. In two (8%) of remaining four cadavers. orifice of LCCA was slightly above the stem of BCT. In remaining two (8%) cadavers, the left vertebral artery (LVA) was directly originated from AA. Average angle of AA curvature to the coronal plane was 62.2 degrees. BCT originated 0.92 mm on the right of the mid-vertebrae line. LCCA and LSCA originated from 12.3 mm and 22.8 mm on the left of the mid-vertebrae line. Mean distance from the origin of the BCT to the origin of the RCCA was 32.5 mm. Mean distance from the origin of the LSCA to the origin of the LVA was 33.8 mm. Average angles at which the major branches arise from the AA were 65.3, 46.9 and 63.8 degrees. Conclusion : This study may provides a basic anatomical information to catheterize AA and its branches for safely performing endovascular surgery.

The purpose of this study was to examine the differences in the brain activation evoked by music arranged in major and minor key used with an identical motion film during the fMRI testing. A part of the audio-visual combinations composed by Iwamiya and Sano were used for the study stimuli. This audio- visual clip was originally developed by combining a small motion segment of the animation "The Snowman" and music arranged in both major and minor key from the original jazz music "Avalon" rewritten in a classical style. Twenty-seven Japanese male graduate and undergraduate students participated in the study. Brain regions more activated by the major key than the minor key when presented with the identical motion film were the left cerebellum, the right fusiform gyrus, the right superior occipital, the left superior orbito frontal, the right pallidum, the left precuneus, and the bilateral thalamus. On the other hand, brain regions more activated by the minor key than the major key when presented with the identical motion film were the right medial frontal, the left inferior orbito frontal, the bilateral superior parietal, the left postcentral, and the right precuneus. The study showed a difference in brain regions activated between the two different stimulus (i.e., major key and minor key) controlling for the visual aspect of the experiment. These findings imply that our brain systematically generates differently in the way it processes music written in major and minor key(Supported by the User Science Institute of Kyushu University, Japan and the Korea Science and Engineering Foundation).

The purpose of this study was to investigate the lifestyle, food habits, image, perception of beauty and nutrition knowledge between beauty major and non-major college female students. A total of 392 women aged 20s in the survey. SPSS version 21.0 was used for analysis of data. The BMI was high in non-major students (p<0.05), proportion of underweight (p<0.001) and non-drinker (p<0.01) were significantly higher in beauty major students than non-major students. Proportion of total subjects skipped meal by the lack of time. Importance of appearance was significantly higher (p<0.05) in beauty major students. Nutrition knowledge score was significantly higher in beauty major students compared to non-major students (p<0.001).In beauty major students, food intake of meats (p<0.001) and cooked food with oil (p<0.01) were lower white vegetables (p<0.05) and fruits (p<0.01) were higher than non-major students. In conclusion, these results suggest that non-major students need to systematic education program about nutrition and diet.
