  • Human papillomavirus (HPV) type 52 is a high-risk HPV responsible for cervical cancer. HPV type 52 is common around the world and is the most common in some Asian regions. The available prophylactic HPV vaccines protect only from HPV types 16 and 18. Supplementing economical vaccines that target HPV type 52 may satisfactorily complement available prophylactic vaccines. A codon-adapted HPV 52 L1 gene was expressed in the methylotrophic yeast Hansenula polymorpha, which is used as an industrial platform for economical hepatitis B surface antigen particle production in China. We found that the recombinant proteins produced in this expression system could form virus-like particles (VLPs) with diameters of approximately 50 nm. This study suggests that the HPV 52 VLPs produced in this platform may satisfactorily complement available prophylactic vaccines in fighting against HPVs prevalent in Asia.

  • This study delved into the effects of labor union members' social media utilization for the formation of labor union social capital. Specifically, this study aimed to identify the effects of labor union-related social media use and participation on the labor union's social capital formation through quantitative and qualitative research. It set up trust, network, and participation as social capital components and as dependent variables. Network, in particular, was divided into bonding and bridging aspect. There is the correlation between labor union-related social media use and the formation of labor union social capital. As participation in the group type social media operated by a labor union becomes more active, evaluation on labor union social capital throughout trust, network, and participation is higher. Especially, the correlation between bonding network and bridging network was high. This proves that a labor union's bond enhancement does not result in the labor union's selfishness, but it can build a cooperative system with an external network.

  • Labor and management relation rises as a key task to solve in order to ensure corporate's sustainable competitiveness in a convergence global environment. The aim of this study is to examine the mediation effect of labor union participation behavior in the effect of convergence-type labor-management conflict on the turnover intention. Data was collected from 491 employees who were employed in medium and small enterprises in Daejeon, Chungcheongnam-do and Chungcheongbuk-do. The results are as follows. Firstly, labor-management conflict had positive (+) effect on labor union participation behavior. Secondly, labor union participation behavior had negative (-) effect on turnover intention. Thirdly, labor union participation behavior had mediating role in the relation between labor-management conflict and turnover intention. Therefore, it is necessary to respond profit and desire of the labor union members by union leaders and to enhance necessity and value of the labor union continually.

  • Ginsenosides are bioactive components of Panax ginseng with many functions such as anti-aging, anti-oxidation, anti-inflammatory, anti-fatigue, and anti-tumor. Ginsenosides are categorized into dammarane, oleanene, and ocotillol type tricyclic triterpenoids based on the aglycon structure. Based on the sugar moiety linked to C-3, C-20, and C-6, C-20, dammarane type was divided into protopanaxadiol (PPD) and protopanaxatriol (PPT). The effects of ginsenosides on skin disorders are noteworthy. They play antiaging roles by enhancing immune function, resisting melanin formation, inhibiting oxidation, and elevating the concentration of collagen and hyaluronic acid. Thus, ginsenosides have previously been widely used to resist skin diseases and aging. This review details the role of ginsenosides in the anti-skin aging process from mechanisms and experimental research.

  • Congenital dilatation of the common bile duct (choledochal cyst) is an uncommon disease. Although the etiology is unknown yet, various theories such as distal obstruction of the common bile duct, congenital weakness of the duct and anomalous union of the pancreaticobiliary duct have been offered to explain the occurrence of choledochal cyst. Thirty - six cases of choledochal cyst over 22 years were analyzed clinically and classified according to Todani's classification and Kimura's anomalous union of pancreaticobiliary duct type. Todani type 1 consisted with 22 cases which were subdivided into 19 cases of type Ia, 1 case of type Ib and 2 of type Ic. Type IVa consisted with 14 cases including one case of Caroli's disease. There were 25 type BP cases and 10 type PB cases and 1 normal pancreatobiliary junction. Serum alkaline phosphatase was increased significantly in almost all cases. Seven patients (19.4%) had associated congenital anomalies such as double gallbladder, left - sided gallbladder, common bile duct web, biliary atresia, accessory hepatic duct, heterotopic pancreas, cleft lip and 2 cases of intestinal malrotation. All patients underwent cyst excision and Roux - en - Y hepaticojejunostomy and cholecystectomy. There was one death due to methicillin resistant Staphylococcus aureus sepsis.

  • Background: Many factors, including molecular ones, were demonstrated to be associated with long-term prognosis of hepatocellular carcinoma (HCC). Thus far, the expression and clinicopathologic and prognostic significance of the carboxyl terminus of Hsp70-interacting protein (CHIP) in B-type hepatitis virus (HBV)-related HCC remain unknown. Materials and Methods: CHIP expression was detected by immunohistochemical staining of surgical samples from 79 patients with HCC with HBsAg positivity. In addition, correlations with clinicopathologic parameters and patient survival were evaluated. Results: It was found that positive CHIP staining was observed in tumor, but not non-tumor, tissues. High expression of CHIP was significantly related to larger tumor size, with marginally significant associations noted for presence of portal vein invasion and higher serum a-fetoprotein level. In addition, univariate analysis showed that high CHIP expression was a powerful predictor for dismal overall and disease-free survival. However, independent prognostic implications of CHIP were not proven in multivariate Cox regression test. Conclusions: CHIP is overexpressed in HBV-related HCC and is associated with unfavorable biological behavior as well as poor prognosis. However, its prognostic role needs to be further validated.

  • In [1], the authors proved that the finite union of linear star-configurations in $\mathbb{P}^2$ has a generic Hilbert function. In this paper, we find the minimal graded free resolution of the union of two linear star-configurations in $\mathbb{P}^2$ of type $s{\times}t$ with $\(^t_2\){\leq}s$ and $3{\leq}t$.

  • To investigate the effectiveness of the freeze-dried allografts and fibrin glue in bone grafts, the status of new bone formation and union of the grafted bone were observed in three types of grafting bones; autogenic bone(AT), allogenic bone(AL), and allogenic bone particles mixed with fibrin glue(FG). These were transplanted into non-union fracture model of 7 adult dogs with 2cm defect made in the proximal metaphysis of both fibulae. The autogenic and allogenic grafting bones had been treated by a modified freeze-dried method. The serial radiogram were observed the repair process of grafted bones biweekly until 17 or 21 weeks after transplantation and the observation of histological aspects, tetracycline double labeling and microradiography in the grafted bones were undertaken at 17 or 21 weeks after transplantation. The incorporation of bone minerals to the non-union fracture models were accomplished in 4 of 5 cases grafted with AL and in 2 of 4 cases grafted with AT. None of 5 cases grafted with FG were incorporated. The process of new bone formation and resorption in the grafted bones were observed three types; resorption of the grafted bones after newbone formation(type A) in 4 cases, new bone formation after resorption(type B) in 2 cases and complete or incomplete resorption without new bone formation(type C) in 8 cases. The modified freeze-dried method used in this study contributed to inhibite the rejection in allogenic grafts but the union period of the grafted freeze-dried bone was more prolonged than that of fresh autografts. Fibrin glue did not contribute to induce a new bone formation ofbone grafts.

  • This study aimed to evaluate the effects of Limosilactobacillus fermentum and Lactiplantibacillus plantarum isolated from human feces coordinating with inulin on the composition of gut microbiota and metabolic profiles in db/db mice. These supplements were administered to db/db mice for 12 weeks. The results showed that the Lactobacillaceae coordinating with inulin group (LI) exhibited lower fasting blood glucose levels than the model control group (MC). Additionally, LI was found to enhance colon tissue and increase the levels of short-chain fatty acids. 16S rRNA sequencing revealed that the abundance of Corynebacterium and Proteus, which were significantly increased in the MC group compared with NC group, were significantly decreased by the treatment of LI that also restored the key genera of the Lachnospiraceae_NK4A136_group, Lachnoclostridium, Ruminococcus_gnavus_group, Desulfovibrio, and Lachnospiraceae_UCG-006. Untargeted metabolomics analysis showed that lotaustralin, 5-hydroxyindoleacetic acid, and 13(S)-HpODE were increased while L-phenylalanine and L-tryptophan were decreased in the MC group compared with the NC group. However, the intervention of LI reversed the levels of these metabolites in the intestine. Correlation analysis revealed that Lachnoclostridium and Ruminococcus_gnavus_group were negatively correlated with 5-hydroxyindoleacetic acid and 13(S)-HpODE, but positively correlated with L-tryptophan. 13(S)-HpODE was involved in the "linoleic acid metabolism". L-tryptophan and 5-hydroxyindoleacetic acid were involved in "tryptophan metabolism" and "serotonergic synapse". These findings suggest that LI may alleviate type 2 diabetes symptoms by modulating the abundance of Ruminococcus_gnavus_group and Lachnoclostridium to regulate the pathways of "linoleic acid metabolism", "serotonergic synapse", and" tryptophan metabolism". Our results provide new insights into prevention and treatment of type 2 diabetes.
