BACKGROUND/OBJECTIVES: UV radiation is a major factor contributing to DNA damage in skin cells, including stem cells and mesenchymal stem cells, leading to the depletion of these crucial cells. This study examined whether a mixture of Indian gooseberry and barley sprout (IB) could inhibit UVB irradiation and 3-isobutyl-1-methylxanthine (IBMX)-induced photoaging and oxidative stress in the skin using HaCaT, Hs27, and B16F10 cells.MATERIALS/METHODS: The moisturizing-related factors, the collagen synthesis-related c-Jun N-terminal kinase (JNK)/c-Fos/c-Jun/matrix metalloproteinases (MMPs) pathway, and the melanogenesis-related cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA)/cAMP-responsive binding protein (CREB)/melanocyte inducing transcription factor (MITF)/tyrosinase-related protein (TRP)/tyrosinase activation pathways were analyzed in vitro by an enzyme-linked immunosorbent assay, real-time polymerase chain reaction, and Western blot analysis. RESULTS: The IB complex increased the hyaluronic acid and sphingomyelin levels and the collagenase inhibitory activity, enhanced hydration-related factors, including collagen, hyaluronic acid synthase (HAS), elastin, long chain base subunit 1 (LCB1) (serine palmitoyltransferase; SPT), and delta 4-desaturase sphingolipid 1 (DEGS1), modulated the inflammatory cytokines levels, antioxidant enzyme activities and the NF-κB/MMPs/cyclooxygenase-2 (COX-2) pathway in UVB-irradiated HaCaT cells, and inhibited wrinkle formation by down-regulation of the JNK/c-Fos/c-Jun/MMP pathway and up-regulation of the transforming growth factor-β receptor I (TGFβR1)/small mothers against decapentaplegic homolog (Smad3)/procollagen type I pathway in UVB-irradiated Hs27 cells. Moreover, the IB complex prevented melanin production by down-regulating the PKA/CREB/MITF/TRP-1/TRP-2 pathway in IBMX-induced B16F10 cells. CONCLUSION These findings suggest that the IB complex has the potential to serve as a safeguard, shielding the skin from UVB radiation-induced photo-damage.

The accuracy and convenience of continuous glucose monitoring (CGM), which efficiently evaluates glycemic variability and hypoglycemia, are improving. There are two types of CGM: professional CGM and personal CGM. Personal CGM is subdivided into real-time CGM (rt-CGM) and intermittently scanned CGM (isCGM). CGM is being emphasized in both domestic and foreign diabetes management guidelines. Regardless of age or type of diabetes, CGM is useful for diabetic patients undergoing multiple insulin injection therapy or using an insulin pump. rt-CGM is recommended for all adults with type 1 diabetes (T1D), and can also be used in type 2 diabetes (T2D) treatments using multiple insulin injections. In some cases, short-term or intermittent use of CGM may be helpful for patients with T2D who use insulin therapy other than multiple insulin injections and/or oral hypoglycemic agents. CGM can help to achieve A1C targets in diabetes patients during pregnancy. CGM is a safe and cost-effective alternative to self-monitoring blood glucose in T1D and some T2D patients. CGM used in diabetes management works optimally with proper education, training, and follow up. To achieve the activation of CGM and its associated benefits, it is necessary to secure sufficient repetitive training and time for data analysis, management, and education. Various supports such as compensation, insurance coverage expansion, and reimbursement are required to increase the effectiveness of CGM while considering the scale of benefit recipients, policy priorities, and financial requirements.

PURPOSE: This study was performed to identify the mediating effect of empowerment in the relationship between head nurses' servant leadership and organizational commitment among clinical nurses. METHODS: A cross-sectional survey design was used. A convenience sample of 249 nurses was recruited from three hospitals located in J province, South Korea. Data were collected by self-report questionnaires, including general characteristics, servant leadership, empowerment, and organizational commitment. Data were analyzed with descriptive statistics, Pearson correlation coefficients, independent t-test, One-way ANOVA, and linear regression using the SPSS 22.0 program. RESULTS: Head nurses' servant leadership perceived by clinical nurses significantly influenced their organization commitment. Empowerment partly mediated the effect of servant leadership on organizational commitment. CONCLUSION: The findings suggest the importance of improving nurse managers' servant leadership and empowering nurses to increase their organizational commitment.

RUNX1, a member of the runt domain gene family of transcription factors, encodes a heterodimeric transcription factor and regulates the expression of various genes related to hematopoiesis and myeloid differentiation. RUNX1 has been one of the target genes for research into various autoimmune diseases due to its properties as a transcription factor and functional distribution for chromosomal translocation. In an effort to identify additional gene polymorphisms in which variants have been implicated in asthma, we investigated the genetic polymorphisms in RUNX1 to evaluate it as a potential candidate gene for a host genetic study of asthma and IgE production. We identified 19 sequence variants by direct DNA sequencing in 24 individuals of which four common variants were selected for genotyping in our asthma cohort (1,055 asthmatic patients, 384 normal controls). Using logistic regression analysis for association with the risk of asthma, while controlling for age, gender, and smoking status as covariates, no significant associations with the risk of asthma were detected. However, two polymorphisms in the promoter region (-2084G>C and -1282G>A) showed a marginal association with total IgE levels (0.03 and 0.03 in recessive models, respectively). Our findings suggest that polymorphisms in RUNX1 might be one of the genetic factors for the regulation of IgE production.

PURPOSE: To evaluate the effectiveness and safety of fentanyl-TTS in the management of radiotherapy induced acute pain and cancer pain treated with radiotherapy. MATERIALS AND METHODS: Our study was open labelled prospective phase IV multi-center study. the study population included patients with more 4 numeric rating scale(NRS) score pain although managed with other analgesics or more than 6 NRS score pain without analgesics. Patients divided into two groups; patients with radiotherapy induced pain (Group A) and patients with cancer pain treated with radiotherapy (Group B). All patients received 25 ug/hr of fentanyl transdermal patch. Primary end point was pain relief; second end points were change in patient quality of life, a degree of satisfaction for patients and clinician, side effects. RESULTS: Between March 2005 and June 2005, 312 patients from 26 participating institutes were registered, but 249 patients completed this study. Total number of patients in each group was 185 in Group A, 64 in Group B. Mean age was 60 years and male to female ratio was 76:24. Severe pain NRS score at 2 weeks after the application of fentanyl was decreased from 7.03 to 4.01, p=0.003. There was a significant improvement in insomnia, social functioning, and quality of life. A degree of satisfaction for patients and clinician was very high. The most common reasons of patients' satisfactions was good pain control. Ninety six patients reported side effect. Nausea was the most common side effect. There was no serious side effect. CONCLUSION: Fentanyl-TTS was effective in both relieving pain with good tolerability and improving the quality of life for patients with radiotherapy induced acute pain and cancer pain treated with radiotherapy. The satisfaction of the patients and doctors was good. There was no major side effect.

Cervical carcinoma is the second leading cause of death from cancer in women worldwide. It is well known that human papillomaviruses (HPVs) is the etiologic agent of cervical neoplasia and cervical cancer. Zinc has been shown to inhibit the growth of malignant cell lines by inducing apoptosis and cell cycle arrest. Recently it was reported that zinc-citrate compound (CIZAR(R)) has a cytotoxic effect on choriocarcinoma cell line and ovarian adenocarcinoma cell line and suppresses its proliferation inducing apoptosis. CIZAR(R) prevents the proliferation by inactivation of m-aconitase activity and induces apoptosis by increasing Bax expression and reducing Bcl-2 expression and inactivation of telomerase. We report one patient of cervical adenocarcinoma with HPV infection, who desires to continue pregnancy, treated by daily topical application of SeLava(R) which contains zinc-citrate compound (CIZAR(R)). We followed up the cytologic, pathologic and coloposcopic changes of healing process.

OBJECTIVE: Human seminal plasma has diverse biological activities including cytotoxic effect. It contains high concentrations of zinc and citric acid. Zinc inhibits several carcinoma cell growths through induction of cell cycle arrest and apoptosis. We tried to investigate the effects of zinc-citrate compound (CIZAR(R)) on normal human ovarian epithelial (NOSE) cells and human epithelial ovarian cancer cells, OVCAR-3. METHODS: To investigate the potential effect of CIZAR(R) on cell growth and survival, cells were treated with different dose and exposed to different time. Mitochondrial(m)-aconitase activity was determined in cell extracts using aconitase assay. The flow cytometric assay, DNA laddering, telomerase activity and morphological analysis were done to investigate apoptosis of OVCAR-3 cells. Molecular mechanism of apoptosis was investigated by p53, Bcl-XL, Bcl-2, Bax protein, and caspase activity. RESULTS: Treatment of OVCAR-3 cells with CIZAR(R) resulted in a time- and dose-dependent decrease in cell number in comparison with NOSE cells. M-aconitase activity was significantly decreased in OVCAR-3 cells but relatively constant in NOSE cells. The flow cytometric assay, DNA laddering and morphological analysis indicated apoptosis of OVCAR-3 cells. CIZAR(R) did not affect p53 but increased the expression of p21waf1 upon the indicated times and induced reduction of telomerase activity. CIZAR(R) reduced expression of Bcl-2 and Bcl-xL proteins but induced expression of Bax protein. CIZAR(R) induced apoptosis of OVCAR-3 cells by activation of caspase-3 pathway. CONCLUSION: These results show that CIZAR(R) prevent the proliferation of OVCAR-3 cells by inactivation of m-aconitase activity and induce apoptosis by induction of apoptotic genes and repression of antiapoptotic genes without adverse effect on normal ovarian epithelial cells. These results will offer new window in prevention and treatment of epithelial ovarian cancer.

Many hemodialysis patients suffer from constipation. The increased incidence of constipation in long-term dialysis patients is based mainly on self-reported data. So, we conducted a survey on 10 hemodialysis patents with constipation by using total and segmental colonic transit time of radio-opaque markers. Segmental colonic transit times were calculated separately for 3 segments of the colon (right, left, and rectosigmoid) and total transit time, which was the sum of all 3 segment times. On results, colonic transit time was significantly prolonged in hemodialysis patient than in healthy control (42.2+/-20.11 versus 10.57+/-12.8 hour; p<0.0001). Increased colonic transit times in the right and especially rectosigmoid segments, but not the left segment, contributed to the prolongation in total colonic transit time. In conclusion, we suggest that colonic transit time measurement is helpful to tailor therapy because it helps us determine the prolonged segment of the colon in hemodialysis patients with constipation.

OBJECTIVE: Comparison of protein expressions by two-dimensional gel electrophoresis (2-DE) in normal cervix and squamous cell carcinoma tissues in Korean women. METHODS: Normal cervix and squamous cell carcinoma tissues were solubilized with 2-DE buffer and the first dimension of PROTEAN IEF CELL, isoelectric focusing (IEF), was performed using pH3-10 linear IPG strips of 17 cm. And then running 12% sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and sliver stain. Scanned image was analyzed using PDQuest 2-D softwareTM. Protein spot spectrum was identified by assisted laser desorption/ionization-time of fighting (MALDI-TOF) and the protein mass spectrum identifications were performed by searching protein databases of Swiss-prot/TrEMBL, Mascot and MS-FIT. RESULTS: We found 9 up-regulation proteins (Alpha enolase, Keratin 19 type I, Keratin 20 type I, Keratin 13 type I, beta-actin, Aflatoxin B1 aldehyde reductase 1, Annexin A2, Squamous cell carcinoma antigen 2, unknown), 7 down-reguation proteins (Annexin 1, Myosin regulatory light chain 2, 14-3-3 protein epsilon, Heat shock 27 kDa protein, Hypothetical protein (DKFZP434C1715), Tumor necrosis factor receptor superfamily member 13B, Smoth muscle protein 22-alpha) and 6 up and down-regulation proteins (Tropomyosin 1, Tropomyosin 2, Tropomyosin 3, Serine (or cysteine) proteinase inhibitor, Phosphatidylinositol transfer protein alpha isoform, Src homology 3 domain-containing protein HIP-55) between normal cervix and squamous cell carcinoma cell tissues. CONCLUSION: 2-DE offers total protein expressions between normal cervix and squamous cell carcinoma cell tissues, and searching of differently expressed protein for the diagnostic markers of squamous cell carcinoma tissue.

We experienced a Korean patient with complete form of pachydermoperiostosis. He presented with typical features consisting of clubbing with spade like enlargement of the hand and feet, thickening of facial skin and scalp, irregular thickening of cortex with periosteal new bone formation involving radii, ulnae, tibiae, and fibulae. Classically, pachydermoperiostosis is characterized by a triad of finger clubbing, periostitis, skin and soft tissue changes, giving an acromegaloid look. A variety of associated abnormalities have been described such as cranial suture defects, female escutcheon, bone marrow failure. There are a few reports documenting gastric ulcer, hypertrophic gastropathy and Crohn's disease as accompanying diseases. The patient had upper gastrointestinal bleeding caused by hemorrhagic gastritis and duodenal ulcer. A case is herein reported of pachydermoperiostosis accompanied by peptic ulcer disease.
