Cordyceps militaris has been reported to the diverse pharmaceutical effects including cancer, inflammatory diseases, and bacteria or virus infection. However, the effect of C. militaris on exercise performance has not yet been elucidated. In this study, we investigated the beneficial effect of C. militaris on exercise performance. To evaluate exercise performance, we prepared C. militaris ethyl acetate extract (CMEE) and conducted grip strength tests every week after administration. Additionally, blood samples were collected at the end of the experiment for biochemical analysis. The administration of CMEE slightly increased grip strength, and this result was similar to the red ginseng treated group. According to the result of biochemical analysis, CMEE had an effect on the biomarkers related to ATP generation pathway but had little influence on the muscle fatigue related biomarkers. Therefore, C. militaris has the possibility of improving exercise performance, which could be associated with the increase in ATP production rather than the decrease in muscle fatigue during exercise.

OBJECTIVE: To evaluate the safety and surgical outcomes of laparoscopically assisted vaginal hysterectomy (LAVH) for women with anterior wall adherence after cesarean section. METHODS: We conducted a retrospective study of 328 women with prior cesarean section history who underwent LAVH from March 2003 to July 2013. The subjects were classified into two groups: group A, with anterior wall adherence (n=49); group B, without anterior wall adherence (n=279). We compared the demographic, clinical characteristics, and surgical outcomes of two groups. RESULTS: The median age and parity of the patients were 46 years (range, 34 to 70 years) and 2 (1 to 6). Patients with anterior wall adherence had longer operating times (175 vs. 130 minutes, P<0.05). There were no significant differences in age, parity, number of cesarean section, body mass index, specimen weight, postoperative change in hemoglobin concentration, or length of hospital stay between the two groups. There was one case from each group who sustained bladder laceration during the vaginal portion of the procedure, both repaired vaginally. There was no conversion to abdominal hysterectomy in either group. CONCLUSION: LAVH is effective and safe for women with anterior wall adherence after cesarean section.

OBJECTIVE: To analyze the preoperative diagnostic clues to ovarian pregnancy (OP). METHODS: This study conducted a retrospective chart review of 23 patients with OP and 46 patients with tubal pregnancy (TP) from October 1, 2003 to September 31, 2016 in Hanyang University Hospital. RESULTS: There were no significant differences in demographic and clinical characteristics between the two groups. The presence of an ectopic gestational sac and hemoperitoneum was significantly higher in the TP group (13.0% vs. 95.7%, P=0.000; 13.0% vs. 54.3%, P=0.001, respectively) in preoperative ultrasonogram. The OP group had more ruptured ectopic gestational sacs than the TP group (73.9% vs. 45.7%, P=0.039) in surgical findings. CONCLUSION: For the patients in whom a gestational sac is not detected in the uterus or the fallopian tubes, it is important to be aware of the possibility of OP and rupture of an ovarian gestational sac to promote early diagnosis and surgical intervention.

Long-lived people may have a unique genetic makeup that makes them more resistant than the general population to prevalent age-related diseases; however, not much is known about genes involved in the longevity. To identify susceptibility variants controlling longevity, we performed a high-throughput candidate gene study using 137 Koreans over 90 yr old and 213 young healthy Koreans. We evaluated 463 informative markers located in 176 candidate genes mostly for diabetes mellitus, cardiovascular disease and cancer under five genetic models. We estimated the odds ratios for each allele, genotype, haplotype, and gene-gene interaction using logistic regression analysis. Associations between 13 genes and longevity were detected at a P-value less than 0.01. Particularly, the rs671 (A) allele of the aldehyde dehydrogenase 2 family (mitochondrial) (ALDH2) gene was associated with longevity only in men (OR 2.11, P = 0.008). Four genes, proprotein convertase subtilisin/kexin type 1 (PCSK1, P = 0.008), epidermal growth factor receptor (EGFR, P = 0.003), paired box 4 (PAX4, P = 0.008), and V-yes-1 Yamaguchi sarcoma viral related oncogene homolog (LYN, P = 0.002) consistently yielded statistical evidence for association with longevity. The findings of the current study may provide a starting point for future studies to unravel genetic factors controlling longevity in Koreans.
