Objective To study the expression of intermediate-conductance-Ca~(2+)-activated K~+ (IKCa1)channels in endometrial cancer and its role in regulating proliferation of endometrial cancer cells. Methods Western blot and RT-PCR were used to examine the expression of IKCa1 channels in 13 normal endometrial specimens and 25 endometrial cancer specimens;and RNA interference(RNAi),[ ~3H ] thymidine incorporation,and inhibitor of IKCa1 channel were used to explore the role of IKCa1 channels in regulation of proliferation of endometrial cancer cells HEC-1A.Results The expression rate and level of IKCa1 mRNA in endometrial carcinoma(84%,0.89?0.52)were higher than in normal endometria(8%, 0.14?0.12;P

OBJECTIVES: This study analyzed Japanese consumers on their sauce consumption, and assessed the relationship between consumer innovativeness and consumption behavior for new sauce products. METHODS: The survey was completed by local consumers visiting Korean restaurants in Osaka, Japan, in September 2018. The demographic characteristics, consumption of sauce, consumer innovativeness, and factors of theory of planned behavior were evaluated. Totally, 150 collected data were analyzed using the IBM SPSS Statistics 25.0 Program (IBM SPSS INC, Armonk, NY, USA). RESULTS: Results of the survey indicate that Japanese consumers purchase a sauce by considering the taste and food utilization. Sauce purchases were maximum at mega markets and supermarkets. The consumer innovativeness for Japanese consumers was based on 3 factors: ‘Purchasing adventurous products (3.51 ± 0.96)’, ‘Active information seeking (4.36 ± 1.11)’, and ‘Interactive information seeking (4.33 ± 1.02)’, where the tendency of ‘Active information seeking’ was the highest innovativeness factor. Furthermore, higher values of perceived behavior control (4.68 ± 1.21), attitude (4.66 ± 1.41) and subjective norm (4.39 ± 1.28) were revealed, when assessing for theory of planned behavior factors. Correlating the variables of consumer innovation and factors of planning behavior theory, ‘Active information seeking’ is a positive attribute for attitude (p<0.016), subjective norm (p<0.001), and perceived behavior control (p<0.002). These 3 factors also had significantly positive effects on purchase intention for new sauce product (p<0.000, p<0.000, and p<0.002, respectively). Attitude was determined to be another very influential variable for purchase intention of a new sauce product (B=0.484, t=6.881). CONCLUSIONS: The results of this study determine the consumption patterns of sauce for the Japanese consumer, and the relationship between consumer innovativeness and consumption behavior for Korean traditional sauces. We believe the data generated from this study will help determine a marketing strategy to enter the Japanese market.

OBJECTIVETo assess the application of IS6110-restriction fragment length polymorphism (RFLP), Spoligotyping and mycobacterial interspersed repetitive unit (MIRU) in epidemiological studies of tuberculosis and to discuss the characteristics of Mycobacterium tuberculosis strains in different regions in China.

METHODSMycobacterium tuberculosis strains, with a total number of 158 isolates, were subjected to IS6110-RFLP, Spoligotyping and MIRU.

RESULTSThe numbers of patterns produced by IS6110-RFLP, Spoligotyping, and MIRU typing were 118, 20 and 105 respectively. The discriminatory power of IS6110-RFLP was higher than that of Spoligotyping. However, when the copies of IS6110 were lower than 10, the discriminatory power of Spoligotyping improved obviously. The discriminatory power of MIRU typing was close to that of IS6110-RFLP for typing of Mycobacterium tuberculosis. In MIRU loci, there were four loci (loci 4, 10, 26, 40) with higher diversity. Significant differences among the Mycobacterium tuberculosis between Guangdong and other regions in clustered rate and the proportion of Beijing genotype (P < 0.05) were found. The clustered rates and the proportion of Beijing genotype in Guangdong were lower than that in other regions.

CONCLUSIONThe results of this study indicated that either IS6110-RFLP, Spoligotyping or MIRU technique was useful for epidemiological studies on tuberculosis in China and the strains in different regions had different characterishes in China.

Vascular malformations are the most common congenital and neonatal vascular anomalies in the head and neck region. The demand for simple and esthetic vascular malformation treatments have increased more recently. In this study, two patients that were diagnosed with venous malformations were treated with sodium tetradecyl sulfate as a sclerosing agent. Recurrence was not found one year after the surgery. This article gives a brief case report of sclerotherapy as an effective approach to treat vascular malformations in the oral cavity.

OBJECTIVE: To investigate the effects of mirror therapy using a tablet PC for post-stroke central facial paresis. METHODS: A prospective, randomized controlled study was performed. Twenty-one post-stroke patients were enrolled. All patients performed 15 minutes of orofacial exercise twice daily for 14 days. The mirror group (n=10) underwent mirror therapy using a tablet PC while exercising, whereas the control group (n=11) did not. All patients were evaluated using the Regional House–Brackmann Grading Scale (R-HBGS), and the length between the corner of the mouth and the ipsilateral earlobe during rest and smiling before and after therapy were measured bilaterally. We calculated facial movement by subtracting the smile length from resting length. Differences and ratios between bilateral sides of facial movement were evaluated as the final outcome measure. RESULTS: Baseline characteristics were similar for the two groups. There were no differences in the scores for the basal Modified Barthel Index, the Korean version of Mini-Mental State Examination, National Institutes of Health Stroke Scale, R-HBGS, and bilateral differences and ratios of facial movements. The R-HBGS as well as the bilateral differences and ratios of facial movement showed significant improvement after therapy in both groups. The degree of improvement of facial movement was significantly larger in the mirror group than in the control group. CONCLUSION: Mirror therapy using a tablet PC might be an effective tool for treating central facial paresis after stroke.

BACKGROUND/OBJECTIVES: Docosahexaenoic acid (DHA), an n-3 long chain polyunsaturated fatty acid (LCPUFA), is acquired by dietary intake or the in vivo conversion of α-linolenic acid. Many enzymes participating in LCPUFA synthesis are regulated by peroxisome proliferator-activated receptor alpha (PPARα). Therefore, it was hypothesized that the tissue accretion of endogenously synthesized DHA could be modified by PPARα. MATERIALS/METHODS: The tissue DHA concentrations and mRNA levels of genes participating in DHA biosynthesis were compared among PPARα homozygous (KO), heterozygous (HZ), and wild type (WT) mice (Exp I), and between WT mice treated with clofibrate (PPARα agonist) or those not treated (Exp II). In ExpII, the expression levels of the proteins associated with DHA function in the brain cortex and retina were also measured. An n3-PUFA depleted/replenished regimen was applied to mitigate the confounding effects of maternal DHA. RESULTS: PPARα ablation reduced the hepatic Acox, Fads1, and Fads2 mRNA levels, as well as the DHA concentration in the liver, but not in the brain cortex. In contrast, PPARα activation increased hepatic Acox, Fads1, Fads2 and Elovl5 mRNA levels, but reduced the DHA concentrations in the liver, retina, and phospholipid of brain cortex, and decreased mRNA and protein levels of the brain-derived neurotrophic factor in brain cortex. CONCLUSIONS: LCPUFA enzyme expression was altered by PPARα. Either PPARα deficiency or activation-decreased tissue DHA concentration is a stimulus for further studies to determine the functional significance.

PURPOSE: To investigate the change in mitogen-activated protein kinase pathways in the brain tissue after therapeutic hypothermia in the swine cardiac arrest model. METHODS: After the return of spontaneous circulation by cardiopulmonary resuscitation, following a 6 min of no-flow time induced by ventricular fibrillation, pigs (n=24) were randomly assigned to one of four groups (sham, normothermia, 24 hr of therapeutic hypothermia, 48 hr of therapeutic hypothermia). After 24 or 48 hr of therapeutic hypothermia (core temperature 32-34℃), the pigs were then rewarmed to 36℃ for a period of 8 hr. At 60 hr upon the return of spontaneous circulation, the pigs were sacrificed and brain tissues were harvested. RESULTS: We measured the tissue levels of p38, JNK, and ERK pathway expressions from the hippocampus of the swine brain in all four groups. The phosphorylated p38-to-p38 ratio and phosphorylated JNK-to-JNK ratio were significantly increased in all of the intervention groups compared with the sham group. The phosphorylated ERK-to-ERK ratio was increased only in the therapeutic hypothermia groups (p-value=0.026 in the 24 hr of therapeutic hypothermia group and p-value=0.002 in the 48 hr of therapeutic hypothermia group, compared with the sham group). CONCLUSION: The p38 and JNK pathways were also activated during therapeutic hypothermia and normothermia. However, the ERK pathway was activated only in therapeutic hypothermia. Therapeutic hypothermia activated the ERK pathway in ischemia-reperfusion injury of the brain tissue after cardiac arrest, which seemed to be dependent on the duration of therapeutic hypothermia.

PURPOSE: Many patients presenting with headache also complain of constipation; the relationship between these two symptoms has not been explored in detail. The aim of this study was to investigate the association between primary headache and constipation. METHODS: This retrospective study included all children who attended the Inje University Sanggye Paik Hospital complaining of headache, and who had been followed up for at least 100 days. Patients were divided into 2 groups: group A, in whom the headache improved after treatment for constipation, and group B, in whom headache was not associated with constipation. RESULTS: Of the 96 patients with primary headache, 24 (25.0%) also had constipation (group A). All 24 received treatment for constipation. Follow-up revealed an improvement in both headache and constipation in all patients. Group B contained the remaining 72 children. Comparison of groups A and B indicated a significant difference in sex ratio (P=0.009, chi-square test). Patients with probable tension-type headache were more likely to be in Group A (P=0.006, chi-square test). CONCLUSION: Resolution of constipation improves headache in many patients diagnosed with primary headache, especially those with probable tension-type headache. We suggest that either constipation plays a key role in triggering headache, or that both constipation and headache share a common pathophysiology.
