A study of proposition and modality focusing on epistemic modals in the Japanese language

This study discusses proposition and modality in the Japanese language, focusing on epistemic modals. In the literature of modality recently, detailed discussions of individual modals have been made to clarify their function. However, clear definitions of proposition and modality have not yet been adequately provided. The issue about whether morphemes such as ta (tense/aspect) and masu (honorific) belong to the modality part has not yet been clarified, and the issue of clarification of the difference between the similar modals yōda and rashii remains unclear. Hence, the first main question concerns whether the sentence consists of proposition and modality (including the classification of modality). The second is how epistemic modals function (whether they express subjectivity or objectivity, and how different similar modals are). In addressing these questions, the study analyses actual examples used in novels and critical essays by use of the phrase-additional and the modal-substitutional methods. Modals used at the end of a sentence are focused on, so modality-expressions appearing at the beginning and in the middle of a sentence are excluded from the subject of this study. This study starts with newly proposing definitions of proposition and modality to distinguish between the two, integrating the following two views: Lyons (1995)’s approach of truth-value from the logical viewpoint, and Japanese scholars such as Teramura’s (1982) approach from the viewpoint of objectivity. By way of the definitions proposed here, the phrasal-discriminator between proposition and modality is established. Consequently, it is shown that any sentence expresses both proposition and modality, and that the copula da/dearu, the polite forms masu and the desiderative tai are propositional parts. Moreover, the new classification of modality is set up from the viewpoint of orientation into three categories: proposition-oriented, situation-oriented, and listener-oriented modality. Thereby, the modality of any sentence can be located in one of the three categories of this classification. This is supported by exploration of the various usages of -ta in chapter 3. In the latter half, in examining similar modals, nodarō and darō, this study has found that nodarō expresses the interpretation of the specific situation, and darō the utterer’s soft claim, and it newly categorises the relationship between judgement and situation in the nodarō sentence. As well, this study has clarified the difference between yōda and rashii, by introducing the concept of ‘inside or outside the utterer’s perceptible domain’. The outcome of this study will contribute to a better and more precise understanding of modality in the Japanese language. In particular, the definitions of proposition and modality and the method of distinguishing them can also be applied to modality-expressions appearing at the beginning and in the middle of a sentence

The Application of a Three-Step Proteome Analysis for Identification of New Biomarkers of Pancreatic Cancer

We searched for novel tumor markers of pancreatic cancer by three-step serum proteome analysis. Twelve serum abundant proteins were depleted using immunoaffinity columns followed by fractionation by reverse-phase high-performance liquid chromatography. Proteins in each fraction were separated by two-dimensional gel electrophoresis. Then the gel was stained by Coomassie Brilliant Blue. Protein spots in which the expression levels were significantly different between cancer and normal control were identified by LC-MS/MS. One hundred and two spots were upregulated, and 84 spots were downregulated in serum samples obtained from patients with pancreatic cancers, and 58 proteins were identified by mass spectrometry. These candidate proteins were validated using western blot analysis and enzyme-linked immunosorbent assay (ELISA). As a result of these validation process, we could confirm that the serum levels of apolipoprotein A-IV, vitamin D-binding protein, plasma retinol-binding protein 4, and tetranectin were significantly decreased in patients with pancreatic cancer

Serum Vaspin Concentrations Are Closely Related to Insulin Resistance, and rs77060950 at SERPINA12 Genetically Defines Distinct Group with Higher Serum Levels in Japanese Population

Context: Vaspin is an adipokine with insulin-sensitizing effects identified from visceral adipose tissues of genetically obese rats. Objective: We investigated genetic and nongenetic factors that define serum concentrations of vaspin. Design, Setting and Participants: Vaspin levels were measured with RIA in Japanese subjects with normal fasting plasma glucose (NFG; n = 259) and type 2 diabetes patients (T2D; n = 275). Single nucleotide polymorphisms (SNP) at SERPINA12 (vaspin) gene locus were discovered, and five SNP were genotyped in the subjects with varied body mass index (n = 1138). Results: The level of serum vaspin in 93% of the samples was found to vary from 0.2 to nearly 2 ng/ml in NFG subjects (n = 259) and from 0.2 to nearly 3 ng/ml in T2D patients (n = 275) (Vaspin(Low) group), whereas a significant subpopulation (7%) in both groups displayed much higher levels of 10-40 ng/ml (Vaspin(High) group). In the Vaspin(Low) group, serum vaspin levels in T2D were significantly higher than healthy subjects (0.99 +/- 0.04 vs. 0.86 +/- 0.02 ng/ml; P < 0.01). Both in T2D and genotyped Japanese population, serum vaspin levels closely correlated with homeostasis model of assessment for insulin resistance rather than anthropometric parameters. By genotyping, rs77060950 tightly linked to serum vaspin levels, i.e. CC (0.6 +/- 0.4 ng/ml), CA (18.4 +/- 9.6 ng/ml), and AA (30.5 +/- 5.1 ng/ml) (P < 2 x 10(-16)). Putative GATA-2 and GATA-3 binding consensus site was found at rs77060950. Conclusions: Serum vaspin levels were related to insulin resistance, and higher levels of serum vaspin in 7% of the Japanese population are closely linked to minor allele sequence (A) of rs77060950.

MEDICAL TREATMENT OF UNRUPTURED CEREBRAL ANEURYSMS

Background: Currently there are no pharmacological therapies for patients with unruptured cerebral aneurysms. Elsewhere we showed that the mineralocorticoid receptor antagonist eplerenone prevented the formation of cerebral aneurysms in our ovariectomized hypertensive aneurysm rat model. The current pilot study evaluated whether it can be used to prevent the growth and rupture of cerebral aneurysms in hypertensive patients. Methods: Between August 2011 and May 2014, we enrolled 82 patients with 90 aneurysms in an open-label uncontrolled clinical trial. All provided prior informed consent for inclusion in this study, and all were treated with eplerenone (25-100 mg/d). The primary end points of our study were the rupture and enlargement of the cerebral aneurysms. Results: Of the 82 patients, 80 (88 unruptured aneurysms) were followed for a mean of 21.3 months (153.4 aneurysm-years); 12 patients (15.0%) permanently discontinued taking the drug. One month after the start of eplerenone administration and throughout the follow-up period, eplerenone kept the blood pressure within the normal range. Most notably, no aneurysms smaller than 9 mm ruptured or enlarged. However, of 2 large thrombosed aneurysms, 1 enlarged and the other ruptured. The overall annual rupture rate was .65%; it was 13.16% for aneurysms larger than 10 mm; the overall annual rate for reaching the primary end points was 1.30%. Conclusion: Our observations suggest that eplerenone may help to prevent the growth and rupture of unruptured cerebral aneurysms smaller than 9 mm. To assess its potential long-term clinical benefits, large clinical trials are needed

Peripheral Blood CD64 Levels Decrease in Crohn's Disease following Granulocyte and Monocyte Adsorptive Apheresis

Granulocyte and monocyte adsorptive apheresis (GMA) is reportedly useful as induction therapy for Crohn's disease (CD). However, the effects of GMA on CD64 have not been well characterized. We report here our assessment of CD64 expression on neutrophils before and after treatment with GMA in two patients with CD. The severity of CD was assessed with the CD activity index (CDAI). The duration of each GMA session was 60 min at a flow rate of 30 ml/min as per protocol. CD64 expression on neutrophils was measured by analyzing whole blood with a FACScan flow cytometer. In case 1, CD64 levels after each session of GMA tended to decrease compared to pretreatment levels, whereas in case 2, CD64 levels dropped significantly after treatment. The CDAI decreased after GMA in both cases 1 and 2. A significant correlation was noted between CDAI scores and CD64 levels in both cases. In conclusion, GMA reduced blood CD64 levels, which would be an important factor for the decrease of CDAI scores

Decreases in the Serum VLDL-TG/Non-VLDL-TG Ratio from Early Stages of Chronic Hepatitis C: Alterations in TG-Rich Lipoprotein Levels

BACKGROUND: The liver secretes very-low-density lipoproteins (VLDLs) and plays a key role in lipid metabolism. Plasma total triglyceride (TG) level variations have been studied in patients with hepatitis C virus (HCV)-related chronic hepatitis (CH-C). However, the results of these studies are variable. A homogenous assay protocol was recently proposed to directly measure the TG content in VLDL (VLDL-TG) and VLDL remnants. METHODOLOGY/PRINCIPAL FINDINGS: Using the assay protocol, we determined serum VLDL-TG levels in 69 fasting patients with biopsy-proven HCV-related chronic liver disease and 50 healthy subjects. Patients were classified into stages F0-F4 using the 5-point Desmet scale. Serum total TG levels in patients with non-cirrhotic (F1-F3) CH-C did not demonstrate significant differences compared with healthy subjects, but serum VLDL-TG levels did demonstrate significant differences. Mean serum VLDL-TG levels tended to decrease with disease progression from F1 to F4 (cirrhosis). Compared with healthy subjects, serum non-VLDL-TG levels significantly increased in patients with stages F2 and F3 CH-C; however, we observed no significant difference in patients with liver cirrhosis. Furthermore, the serum VLDL-TG/non-VLDL-TG ratio, when taken, demonstrated a significant decrease in patients with CH-C from the mildest stage F1 onward. CONCLUSIONS/SIGNIFICANCE: The decrease in serum VLDL-TG levels was attenuated by increase in non-VLDL-TG levels in patients with non-cirrhotic CH-C, resulting in comparable total TG levels. Results of previous studies though variable, were confirmed to have a logical basis. The decrease in the serum VLDL-TG/non-VLDL-TG ratio as early as stage F1 demonstrated TG metabolic alterations in early stages of CH-C for the first time. The involvement of TG metabolism in CH-C pathogenesis has been established in experimental animals, while conventional TG measurements are generally considered as poor indicators of CH-C progression in clinical practice. The serum VLDL-TG/non-VLDL-TG ratio, which focuses on TG metabolic alterations, may be an early indicator of CH-C

Development of a Multifunctional Lightweight Membrane with a High Specific Power Generation Capacity

As a lighter power generation system, Japan Aerospace Exploration Agency (JAXA) and Sakase Adtech Corp. are developing a demonstrator component named “Harvesting Energy with Lightweight Integrated Origami Structure” (HELIOS), which is a deployable lightweight membrane structure. HELIOS has solar arrays on its surface and demonstrates the technology which enables higher specific power generation capacity compared to the conventional solar array panels. The membrane also has communication antennas, showing the potency of lightweight membrane’s multifunctionality such as large data transmitting by 5G antennas and high-resolution observation by interferometer antennas. This paper presents the component’s concept and design, and the expected achievements
