Sinistral En Echelon Folding of the Sambagawa Schists and Its Tectonic Implication

The folds of the Sambagawa schists, which were produced during the last phase (Hijikawa—Oboke phase = Dh phase) of their folding history, are developed as a series of sinistral en echelon upright folds with half wavelength of less than 20 Km (Hara et al.,1977,1992). The Dh phase folds in Shikoku are accompanied with two culminations, Oboke culmination and Nakashichiban culmination, placed near the MTL. Their movement picture during the formation process of such the Dh phase folds has been analyzed on the basis of orientation pattern of parasitic folds and quartz microtextures. It has been clarified that the Dh phase folds were produced by left—lateral shear under N —S compression, being accompanied by the southward tectonic emplacement of two rigid bodies which gave rise to the Oboke and Nakshichiban culminations. These bodies can be assumed to be granitic and/or high—temperature metamorphic rocks tectonically derived from the Kurosegawa—Koryoke continent, as judged from the seismic refraction data in the Oboke district after Ichikawa (1968)

Influences of shot-peening on fine grain steels

Recently, fine grain steel has been actively researched. However, as we know, the influence concerning the shot peening processing to fine grain steels has been few reported up to now. Therefore residual stress distribution near the surface of fine grain steel after shot-peening was measured by X-ray diffraction technology. Moreover, the hardening effect the distributed near the shot-peened surface was also estimated. The relationships between the effects of shot-peening and the grain size of material were discussed.

Relevance of the Core 70 and IL-28B polymorphism and response-guided therapy of peginterferon alfa-2a ± ribavirin for chronic hepatitis C of Genotype 1b: a multicenter randomized trial, ReGIT-J study

BACKGROUND: We conducted a multicenter randomized clinical trial to determine the optimal treatment strategy against chronic hepatitis C virus (HCV) with genotype 1b and a high viral load (G1b/high). METHODS: The study subjects included 153 patients with G1b/high. Patients were initially treated with PEG-IFNα-2a alone and then randomly assigned to receive different treatment regimens. Ribavirin (RBV) was administered to all patients with HCV RNA at week 4. Patients negative for HCV RNA at week 4 were randomly assigned to receive PEG-IFNα-2a (group A) or PEG-IFNα-2a/RBV (group B). Patients who showed HCV RNA at week 4 but were negative at week 12 were randomly assigned to receive weekly PEG-IFNα-2a (group C) or biweekly therapy (group D). Patients who showed HCV RNA at week 12 but were negative at week 24 were randomly assigned to receive PEG-IFNα-2a/RBV (group E) or PEG-IFNα-2a/RBV/fluvastatin (group F). RESULTS: Overall, the rate of sustained virological response (SVR) was 46 % (70/153). The total SVR rate in the group (A, D, and F) of response-guided therapy was significantly higher than that in the group (B, C, and E) of conventional therapy [70 % (38/54) versus 52 % (32/61), p = 0.049]. Although IL28-B polymorphism and Core 70 mutation were significantly associated with efficacy, patients with rapid virological response (RVR) and complete early virological response (cEVR) achieved high SVR rates regardless of their status of IL-28B polymorphism and Core 70 mutation. CONCLUSION: In addition to knowing the IL-28B polymorphism and Core 70 mutation status, understanding the likelihood of virological response during treatment is critical in determining the appropriate treatment strategy

Risk factors related to the reduction of subjective taste ability in middle-to old-aged nursing home residents in Sri Lanka : a cross-sectional study

The purpose of this study is to verify the factors significantly related to the reduction of subjective taste ability of 1,015 middle-aged and elderly (50 - 96 years old) at 25 randomized selected nursing homes in Sri Lanka. Binary logistic regression analyses by gender were performed using IBM SPSS on following variables. A dependent variable is taste ability, and 27 independent variables are age, daily lifestyle, nutritional problems, general status, dental status and physiological thresholds of taste abilities (sweet, salt, sour, bitter, and umami). Smell ability (p < 0.001 - 0.05) and the Self-Report Questionnaire, 20-item version :SRQ 20 (p < 0.01 - 0.05) were significant risk factors of reducing taste ability in both genders. Especially, smell ability was closely linked to taste ability. Existence of comprehensive perception of “flavor” composed of taste and smell ability was illustrated. Significant gender differences factors were observed in long term care needs (p < 0.05), sleeping (p < 0.01 - 0.001), bowel condition (p < 0.05) in males; and height (p < 0.05), weight (p < 0.05), BMI 3 categories (p < 0.05), and brushing (p < 0.05) in females. Other variables such as age and five types of physiological taste ability were not significant in both genders. The results of this investigation also strongly indicated that the perception of subjective sense of taste was different from the objective sense of taste. Epidemiological studies such as cohort or intervention studies focusing on a relationship between subjective taste ability and sense of smell are necessary to identify more accurate and changeable risk factors for dysgeusia in order to improve elderly’s nutritional intake in Sri Lanka

Glucose Metabolism in Cataractous Lens

Since the sorbitol pathway in the lens of a diabetic rat was discovered, the relation between cataract formation and aldose reductase has been studied. We measured glucose, sorbitol and fructose in the human cataractous lens by the gaschromatography. Additionally, we measured sugar and polyols in bovine, pig and rabbit lens. The ratio of sorbitol/glucose is high in rabbit, pig and bovine lens in order. In the human cataractous lens, glucose is increased in accordance with development of cataract. On the other hand, sorbitol content is high in the diabetic lens and low in the senile cataractous lens. The aldose reductase inhibitor may have beneficial effects in the prevention of diabetic cataract formation, but have not the therapeutic effect in the senile cataract
