Background Miniature pigs have been increasingly used as mammalian model animals for biomedical research because of their similarity to human beings in terms of their metabolic features and proportional organ sizes. However, despite their importance, there is a severe lack of genome-wide studies on miniature pigs. Objective In this study, we performed whole-genome sequencing analysis of 20 Micro-pigs obtained from Medi Kinetics to elucidate their genomic characteristics. Results Approximately 595 gigabase pairs (Gb) of sequence reads were generated to be mapped to the swine reference genome assembly (Sus scrofa 10.2); on average, the sequence reads covered 99.15% of the reference genome at an average of 9.6-fold coverage. We detected a total of 19,518,548 SNPs, of which 8.7% were found to be novel. With further annotation of all of the SNPs, we retrieved 144,507 nonsynonymous SNPs (nsSNPs); of these, 5968 were found in all 20 individuals used in this study. SIFT prediction for these SNPs identified that 812 nsSNPs in 402 genes were deleterious. Among these 402 genes, we identified some genes that could potentially affect traits of interest in Micro-pigs, such as RHEB and FRAS1. Furthermore, we performed runs of homozygosity analysis to locate potential selection signatures in the genome, detecting several loci that might be involved in phenotypic characteristics in Micro-pigs, such as MSTN, GDF5, and GDF11. Conclusion In this study, we identified numerous nsSNPs that could be used as candidate genetic markers with involvement in traits of interest. Furthermore, we detected putative selection footprints that might be associated with recent selection applied to miniature pigs.

The purpose of this study was to analyze risk of falls between elderly people and college students. The subjects of this study were 25 people aged 70 years or older and 17 college students located in Asan. We measured sensory, integrated balance, nervous, musculoskeletal system and HQR by FRA system (Inbody, Korea). The results of measurement showed significant differences in sensory system (p<.01), integrated balance (p<.001), nervous system (p<.001), and musculoskeletal system (p<.001) between groups. These results suggest that aging makes difference of function of these systems. In our view, counterplans need to be implemented, including exercise intervention to prevent decreases of fall risk,

Muscle fatigue is a symptom that decreases your muscles’ ability to perform over time. It can be associated with a state of exhaustion, often following excessive sports activity or exercise. While exercise is a common cause of muscle fatigue, this symptom can be the result of other health conditions. Muscle fatigue caused by excessive activity limits activities of daily living and difficult to maintain a stable posture. Therefore, the purpose of this study was to investigate the effect of stretching, icing, and sports massage on muscle fatigue recovery.

Purpose: The aim of this study was to assess the diagnostic efficacy of noninvasive prenatal screening for trisomy 18 by assessing the levels of unmethylated-maspin (U-maspin) and fetal nuchal translucency (NT) thickness during the first trimester of pregnancy. Materials and Methods: A nested case-control study was conducted using maternal plasma samples collected from 65 pregnant women carrying 11 fetuses with trisomy 18 and 54 normal fetuses. We compared the U-maspin levels, NT thicknesses, or a combination of both in the first trimester between the case and control groups. Results: U-maspin levels and NT thickness were significantly elevated in the first trimester in pregnant women carrying fetuses with trisomy 18 when compared to those carrying normal fetuses (27.2 vs. 6.6 copies/mL, P<0.001 for U-maspin; 5.9 vs. 2.0 mm, P<0.001 for NT). The sensitivities of the U-maspin levels and NT thickness in prenatal screening for fetal trisomy 18 were 90.9% and 90.9%, respectively, with a specificity of 98.1%. The combined U-maspin levels and NT thickness had a sensitivity of 100% in prenatal screening for fetal trisomy 18, with a specificity of 98.1%. Conclusion: A combination of U-maspin levels and NT thickness is highly efficacious for noninvasive prenatal screening of fetal trisomy 18 in the first trimester of pregnancy.

EP was obtained through 20% ethanol extraction of Pueraria lobata root, and the fermented form of EP, FEP, was prepared from the EP after incubating with Lactobacillus rhamnosus vitaP1. There was no significant toxicity by EP and FEP up to 1000 ㎍/㎖ in NIH-3T3, HaCaT, and B16F10 cells. In addition to antioxidant potentials of EP and FEP determined by DPPH and ABST assays, we confirmed increase of procollagen type I and elastin synthesis by supplementation of the EP and FEP at the concentration of 50 ㎍/㎖ using ELISA kits. The protein expression levels of matrix metalloprotease (MMP)-1, -3, and -9, those are involved in the degradation of collagen or other skin matrix proteins, were remarkably suppressed while their inhibitory protein metallopeptidase inhibitor 1 (TIMP-1) was greatly up-regulated by supplementation of the EP and FEP at a concentration of 50 ㎍/㎖. Taken together, both EP and FEP supplementation could be involved in the suppression of the skin wrinkle formation through inhibiting degradation of collagen and stimulating the synthesis of collagen and elastin. The results showed that the anti-wrinkle potential of the EP and FEP will be a promising candidate for developing cosmeceutical compounds or products.

BACKGROUND/OBJECTIVES: Benign prostatic hypertrophy (BPH) is a major cause of abnormal overgrowth of the prostate mainly in the elderly. Corni Fructus has been reported to be effective in the prevention and treatment of various diseases because of its strong antioxidant effect, but its efficacy against BPH is not yet known. This study was designed to evaluate the therapeutic efficacy of Corni Fructus water extract (CF) in testosterone-induced BPH rats. MATERIALS/METHODS: To induce BPH, rats were intraperitoneal injected with testosterone propionate (TP). Rats in the treatment group were orally administered with CF with TP injection, and finasteride, which is a selective inhibitor of 5α-reductase type 2, was used as a positive control. RESULTS: Our results showed that the increased prostate weight and histopathological changes in BPH model rats were suppressed by CF treatment. CF, similar to the finasteride-treated group, decreased the levels of testosterone and dihydrotestosterone by TP treatment in the serum, and it also reduced 5α-reductase expression and concentration in prostate tissue and serum, respectively. In addition, CF significantly blocked the expression of the androgen receptor (AR), AR co-activators, and proliferating cell nuclear antigen in BPH rats, and this blocking was associated with a decrease in prostate-specific antigen levels in serum and prostate tissue. CONCLUSIONS: These results suggest that CF may weaken the BPH status through the inactivation of at least 5α-reductase and AR activity and may be useful for the clinical treatment of BPH.

수정란이 착상하는 동안 모체의 생식 기관에서 면역 세포 군집의 변화가 발생하며 이는 임신 과정의 핵심이다. 착상 전·후 기간동안 T 림프구를 포함한 면역 세포는 이식 초기에 생식 기관으로 불러들여지며, T 림프구 중 보조T세포인 Th1과 Th2 사이의 균형은 착상의 성공에 중요한 영향을 미친다. 본 연구에서는 돼지 수정란 착상 전 모체의 난관(OVI), 자궁내막 (ENDO), 자궁 점막층 (UML)에서 Th1, Th2의 균형을 확인하고자 종양괴사인자-알파 (TNF-α)와 인터루킨-10 (IL-10)의 농도를 효소결합 면역흡착 분석법 (ELISA)을 이용해 분석하였다. IL-10의 경우 7일차에 OVI, ENDO, UML에 유의한 차이가 있었으나 (p < 0.01), TNF-α의 경우 모두 유의한 차이가 없었다. IL-10:TNF-α 비율은 OVI에서만 7일째에 유의한 차이가 나타났다 (p < 0.05). 본 연구의 결과는 착상 전 생식 기관별 염증-항염증 기전의 변화를 통해 모체의 생식계가 배아를 수용하는 과정의 일부를 뒷받침할 수 있다. After implantation, dramatic shifts in immune cell populations occur in the maternal reproductive tract, and these changes are key to the implantation and pregnancy process in sows. Immune cells, including T lymphocytes, are recruited during the early implantation period, and an accurate balance between Th1 and Th2 is essential for successful implantation. In this study, the concentration of TNF-α (tumor necrosis factor-alpha) and IL-10 (interleukin-10) in early pregnancy were investigated using an enzyme-linked immunosorbent assay (ELISA) to determine Th1/Th2 ratios in oviduct (OVI), endometrium (ENDO), and the uterine mucosal layer (UML) before implantation. Significant differences in IL-10 levels were observed in OVI, ENDO, and UML tissues on day 7 post-implantation (p < 0.01), whereas TNF-α levels were no different. As regards IL-10 and TNF-α ratios, a significant difference was found on day 2 in OVI tissues (p < 0.05). The result of this study supports the notion that the maternal reproductive system accepts the embryo through changes in preimplantation reproductive system-specific pro-/anti-inflammatory mechanisms.
