An Examination of Factors Affecting Japanese Tourism in Hawaii

The Japanese tourist market is a crucial component of the Hawaii tourism economy due to both market size and higher per capita expenditures in comparison with other key markets for the state. Over the past decade, annual Japanese tourist arrivals have decreased significantly off a peak in 1997. This study examines various supply and demand factors, which may be influencing Japanese tourist arrivals to Hawaii using regression analysis. Results show that five of eight variables significantly influence the monthly Japanese tourist numbers to Hawaii: monthly total Japanese overseas tourists, available air seats, average room rates, available room units, and change in security checking procedure. Meanwhile, three variables were not found to be significant influencers: mean monthly exchange rate ($/100 Yen), anti-smoking law, and airline fuel surcharges. These results do not support the anecdotes and conjectures about the decreasing number of Japanese tourists to Hawaii

Anti-periodic solutions to a parabolic hemivariational inequality

summary:In this paper we deal with the anti-periodic boundary value problems with nonlinearity of the form $b(u)$, where $b\in L^{\infty }_{{\rm loc}}({R}).$ Extending $b$ to be multivalued we obtain the existence of solutions to hemivariational inequality and variational-hemivariational inequality

Successful Use of Newspapers in Curriculum Development for First-year College Students

The course, Fashion and Society, is designed to provide first-year Clothing and Textiles major students with an integrated view of fashion as social phenomenon. From the survey on the first-year students’ perceptions about fashion, we have found that many students considered fashion tend to be irrelevant, something fancy and distant to their daily life, and difficult to understand. Based on the comments, we need teaching materials that can be perceived to be “not difficult” (and fun) and relevant. We also needed to design the course to provide students opportunities to apply their knowledge to real life. Thus, we developed the course using several newspapers to help students experience various fashion expressions and reflections a society carries in

Characterisation of Pseudomonas aeruginosa related to bovine mastitis

Pseudomonas aeruginosa is one of the causative pathogens of bovine mastitis. Most P. aeruginosa strains possess the type III secretion system (TTSS), which may increase somatic cell counts (SCCs) in milk from mastitis-affected cows. Moreover, most of P. aeruginosa cells can form biofilms, thereby reducing antibiotic efficacy. In this study, the presence and effect of TTSS-related genotypes on increase of SCCs among 122 P. aeruginosa isolates obtained from raw milk samples from mastitis-affected cows and their antibiotic susceptibility at planktonic and biofilm status were investigated. Based on the presence of TTSS-related genes a total of 82.7% of the isolates were found to harbour exoU and/or exoS genes, including the invasive (exoU-/exoS+, 69.4%), cytotoxic (exoU+/exoS-, 8.3%) and cytotoxic/invasive strains (exoU+/ exoS+, 5.0%). Milk containing exoS-positive isolates had higher SCCs than those containing exoS-negative isolates. The majority of isolates showed gentamicin, amikacin, meropenem and ciprofloxacin susceptibility at planktonic status. However, the susceptibility was decreased at the biofilm status. Based on minimum biofilm eradication concentration (MBEC)/minimum inhibitory concentration (MIC) ratios, the range of change in antibiotic susceptibility varied widely depending on the antibiotics (from ≥ 3.1-fold to ≥ 475.0-fold). In conclusion, most P. aeruginosa isolates studied here had a genotype related to increase in SCCs. The efficiency of antibiotic therapy against P. aeruginosa-related bovine mastitis could be improved by analysing both the MBEC and the MIC of isolates

A New p53 Target Gene, RKIP, Is Essential for DNA Damage-Induced Cellular Senescence and Suppression of ERK Activation

Abstractp53, a strong tumor suppressor protein, is known to be involved in cellular senescence, particularly premature cellular senescence. Oncogenic stresses, such as Ras activation, can initiate p53-mediated senescence, whereas activation of the Ras-mitogen-activated protein kinase (MAPK) pathway can promote cell proliferation. These conflicting facts imply that there is a regulatory mechanism for balancing p53 and Ras-MAPK signaling. To address this, we evaluated the effects of p53 on the extracellular signal-regulated kinase (ERK) activation and found that p53 could suppress ERK activation through de novo synthesis. Through several molecular biologic analyses, we found that RKIP, an inhibitor of Raf kinase, is responsible for p53-mediated ERK suppression and senescence. Overexpression of RKIP can induce cellular senescence in several types of cell lines, including p53-deficient cells, whereas the elimination of RKIP by siRNA or forced expression of ERK blocks p53-mediated cellular senescence. These results suggested that RKIP is an essential protein for cellular senescence. Moreover, modification of the p53 serine 46 residue was critical for RKIP induction and ERK suppression as well as cellular senescence. These results indicated that RKIP is a novel p53 target gene that is responsible for p53-mediated cellular senescence and tumor suppressor protein expression

Perspective of mesenchymal transformation in glioblastoma.

Despite aggressive multimodal treatment, glioblastoma (GBM), a grade IV primary brain tumor, still portends a poor prognosis with a median overall survival of 12-16 months. The complexity of GBM treatment mainly lies in the inter- and intra-tumoral heterogeneity, which largely contributes to the treatment-refractory and recurrent nature of GBM. By paving the road towards the development of personalized medicine for GBM patients, the cancer genome atlas classification scheme of GBM into distinct transcriptional subtypes has been considered an invaluable approach to overcoming this heterogeneity. Among the identified transcriptional subtypes, the mesenchymal subtype has been found associated with more aggressive, invasive, angiogenic, hypoxic, necrotic, inflammatory, and multitherapy-resistant features than other transcriptional subtypes. Accordingly, mesenchymal GBM patients were found to exhibit worse prognosis than other subtypes when patients with high transcriptional heterogeneity were excluded. Furthermore, identification of the master mesenchymal regulators and their downstream signaling pathways has not only increased our understanding of the complex regulatory transcriptional networks of mesenchymal GBM, but also has generated a list of potent inhibitors for clinical trials. Importantly, the mesenchymal transition of GBM has been found to be tightly associated with treatment-induced phenotypic changes in recurrence. Together, these findings indicate that elucidating the governing and plastic transcriptomic natures of mesenchymal GBM is critical in order to develop novel and selective therapeutic strategies that can improve both patient care and clinical outcomes. Thus, the focus of our review will be on the recent advances in the understanding of the transcriptome of mesenchymal GBM and discuss microenvironmental, metabolic, and treatment-related factors as critical components through which the mesenchymal signature may be acquired. We also take into consideration the transcriptomic plasticity of GBM to discuss the future perspectives in employing selective therapeutic strategies against mesenchymal GBM

Hippocampal sclerosis and encephalomalacia as prognostic factors of tuberculous meningitis-related and herpes simplex encephalitis-related epilepsy

AbstractBackgroundTuberculous meningitis (TBM) and herpes simplex encephalitis (HSE) are common neurological diseases involving the brain parenchyma, and both can result in chronic epilepsy. Here, we identified possible variables affecting the prognosis of central nervous system (CNS) infection-related epilepsy.MethodsThe clinical seizure characteristics and demographic data of 20 TBM- and 55 HSE-related epilepsy patients were compared. Statistically significant prognostic variables were identified using multiple regression analysis.ResultsSex, age at infection, age at epilepsy onset, presence of seizures at the time of infection, latency period, and seizure characteristics between two groups were similar except for the pattern of brain lesions observed on the MRI and their overall prognosis. Patients with hippocampal sclerosis (HS) only comprised 30% and 52.7% of the TBM and HSE groups, respectively. Encephalomalacia had a positive effect in the HSE group while HS had a negative effect in this group, but no significant effects were found in the TBM group. Through a multiple regression analysis with a correction for group effects, HS was associated with a poor prognosis. However, encephalomalacia was concomitantly associated with a good prognosis. In addition, a short latency period, with a one-year interval, and being male were both associated with a good prognosis, while the age at the onset of epilepsy was associated with a poor prognosis.ConclusionsThis study suggests that HS and encephalomalacia could have mutual but contradictory effects on the prognosis of CNS infection-related epilepsy
