ObjectiveWe analyzed the clinical outcomes of Meckel’s cave compression with Teflon (Rhee’s method) as a new modified and additional surgical technique for trigeminal neuralgia (TN). MethodsBetween March 1996 and December 2014, out of 78 patients who were treated with microvascular decompression (MVD) or partial sensory root rhizotomy, 28 patients additionally underwent Meckel’s cave compression with Teflon. The mean age at initial treatment was 54.3 years (range: 40-69 years). The mean duration from onset to operation was 70.5 months (range: 5-360 months) and the mean follow-up period was 26 months (range: 1-77 months). ResultsFifteen patients (53.6%) had facial pain in the V2/V3 distribution. The offending or associating vessel was the superior cerebellar artery in four patients (14.3%), the superior petrosal vein in six (21.4%), the anterior inferior cerebellar artery in two (7.1%), multiple vessels in nine (32.1%), and miscellaneous arteries or veins in six (21.4%). One patient (3.6%) had no offending vessel, and seven patients were had no definite offending vessels that contacted the trigeminal root entry zone. Meckel’s cave compression with Teflon was applied to all patients: 10 (35.7%) in combination with MVD, one (3.6%) with partial rhizotomy, and 17 (60.7%) with both MVD and partial rhizotomy. TN was relieved in 26 patients (92.9%) and symptoms recurred in three patients. The complication rate of this method appeared to be similar to other treatment procedures. ConclusionMeckel’s cave compression with Teflon may be a safe and useful additional treatment procedure for TN.

In this study, we examined the effect of H-87, specific inhibitor of protein kinase A, on in vitro sensitivities of mouse leukemia cell line P388 resistant to several antitumor agents. H-87 significantly potentiated the cytotoxic effects of ADM, VCR and VBL on P388 cells resistant to these antitumor agents. Thus we examined the mechanism of overcoming multidrug resistance by H-87. In northern blot analysis, H-87-treated resistant P388 cell lines showed less MDR1 gene expression than untreated control cells. As a result of CAT assay, the expression of MDRI promoter was inhibited by H-87 in a concentration-dependent manner. To compare the effect of H-87 with that of staurosporine(PKC inhibitor), we examined the effect of staurosporine on in vitro sensitivities of mouse leukemia cell line resistant to several antitumor agents. The expression of MDR1 gene in multidrug resistant P388 cells was decreased by staurosporine. The activity of MDR1 promoter was increased by TPA(PKC activator) and forskolin(adenylate cyclase activator). Therefore, we speculate that PKA and PKC may play important roles in the regulation of MDRI gene expression.

The environmental and ethical concerns raised by the fashion industry have highlighted the need for sustainable fashion. Consequently, upcycling production methods have attracted considerable attention as alternative solutions. This study examines the effect of upcycling fashion brand image on brand equity, which further influences behavioral intentions, and investigates how the relationship between brand image and brand equity differs according to the acceptance of green peer influence. The study collected and analyzed 432 survey responses. Functional, symbolic, and hedonic brand images, which are all subdimensions of upcycling fashion brand image, were found to have a positive impact on brand equity. However, CSR (Corporate Social Responsibility) brand image did not exhibit a significant effect on brand equity. The study also found that the effect of CSR brand image on brand equity was significantly higher for the high green peer influence group than for the low green peer influence group, with only the high green peer influence group having statistical significance. This study suggests certain theoretical implications to applying brand equity theory in the upcycling fashion brand context and certain practical implications to building upcycling fashion branding strategies.
