Aims: Chronic low-grade inflammation and/or obesity are suggested to induce chronic kidney disease (CKD) in patients with type 2 diabetes. This cross-sectional study was performed to investigate the relationship between inflammatory biomarkers and CKD in non-obese patients with type 2 diabetes. Methods: 106 non-obese Japanese patients with type 2 diabetes were recruited for the measurement of GFR, TNF, HMW adiponectin, leptin, hsCRP and some variables including urinary albumin. BMI, serum creatinine, and urinary albumin levels were 22.2±0.2kg/m2 (17.1-24.9kg/m2), 0.76±0.02mg/dl (0.39-1.38mg/dl), 40.4±4.3mg/gCr (1.6-195.0mg/gCr), respectively. They were stratified into two groups based on the value of eGFR: low eGFR (eGFR<60ml/min/1.73m2) and normal eGFR (eGFR>60ml/min/1.73m2). Logistic regression analysis was used for statistical analysis. Results: Whereas univariate logistic regression analysis showed that gender, diabetes duration, triglyceride, HDL cholesterol, uric acid, urinary albumin, and soluble TNF receptors (sTNF-R1, sTNF-R2) are associated with the development of stage 3 CKD, multivariate logistic regression analysis revealed that sTNF-R2 (Odds ratio 1.003, 95% confidence interval 1.000 to 1.005, P= 0.030) showed significant associations with the development of stage 3 CKD. Conclusions: Circulating TNF receptor 2 is an independent risk factor for CKD in non-obese Japanese patients with type 2 diabetes. © 2013.

Humans ability to recognize objects is remarkably robust across a variety of views unless faces are presented upside-down. Whether this face inversion effect (FIE) results from qualitative (distinct mechanisms) or quantitative processing differences (a matter of degree within common mechanisms) between upright and inverted faces has been intensely debated. Studies have focused on preferential responses to faces in face-specific brain areas, although face recognition also involves nonpreferential responses in non-face-specific brain areas. By using dynamic causal modeling with Bayesian model selection, here we show that dissociable cortical pathways are responsible for qualitative and quantitative mechanisms in the FIE in the distributed network for face recognition. When faces were upright, the early visual cortex (VC) and occipital and fusiform face areas (OFA, FFA) suppressed couplings to the lateral occipital cortex (LO), a primary locus of object processing. In contrast, they did not inhibit the LO when faces were inverted but increased couplings to the intraparietal sulcus, which has been associated with visual working memory. Furthermore, we found that upright and inverted face processing together involved the face network consisting of the VC, OFA, FFA, and inferior frontal gyrus. Specifically, modulatory connectivity within the common pathways (VC-OFA), implicated in the parts-based processing of faces, strongly correlated with behavioral FIE performance. The orientation-dependent dynamic reorganization of effective connectivity indicates that the FIE is mediated by both qualitative and quantitative differences in upright and inverted face processing, helping to resolve a central debate over the mechanisms of the FIE.

Objective: Metabolic syndrome contains many risks for medical diseases such as cardiovascular disease and diabetes, which might precipitate depressive symptoms in the older people. However, the association between depressive symptoms and metabolic syndrome in Japanese community-dwelling older people is unclear. This study was performed to answer this important question. Methods: Cross-sectional analyses were performed on 3796 community-dwelling independent older people (≥65 years, 1911 men and 1885 women) from the 2007-2008 baseline examination of the Fujiwara-kyo study, a prospective cohort study on successful aging. Depressive symptoms were assessed using the 15-item short form of the Geriatric Depression Scale and metabolic syndrome was defined according to the 2005 International Diabetes Federation. Covariates were social supports, negative life events, health behavior, education, cognitive function, anthropometric status, and others. Multiple logistic regression analyses were performed to determine the relationships between depressive symptoms and these variables. Results: The prevalence of depressive symptoms (Geriatric Depression Scale-15 ≥6) and metabolic syndrome were 14.8% and 16.6%, respectively. Significant protective factors against depressive symptoms were higher education, more opportunity for drinking of alcohol, better social supports, and more walking daily. Metabolic syndrome was statistically associated with depressive symptoms (adjusted odds ratio = 1.32, 95% confidence interval = 1.03-1.68). Other risk factors significantly associated with depressive symptoms were sleep disturbance, visual or hearing impairment, and negative life events. Conclusions: The present study showed an association between metabolic syndrome and depressive symptoms in ambulatory Japanese older people, as in western countries.

Kudzu is an aggressive invasive weed introduced from Japan to the United States. A 2-year survey of herbivorous insects on this plant in central Japan found 47 potential kudzu-feeding species, including 5 likely specialists. The leaf-miner Trachys auricollis is the most promising agent for biological control of kudzu.

Stream macroinvertebrate assemblages are expected to be affected by the abundance and constitution of litter from surrounding forests. We compared forest floor cover, overland flow, stream environment, and stream macroinvertebrate assemblages between the catchments of a Japanese cedar plantation (CP) and a primary deciduous forest (DF). Both systems experience excessive deer browsing. Understory vegetation cover was higher in the DF than in the CP in summer, although cover was low (&20 %), possibly because of excessive deer browsing. Litter cover was much higher in the CP than in the DF in summer as a result of the long abscission period, slow breakdown, and low rate of dispersal of Japanese cedar litter compared to deciduous litter. Monthly overland flow was always lower in the CP than in the DF, and substrate size was smaller in the DF stream. In the CP, cedar litter accumulated in the stream, probably because of its low breakdown rate and morphology, and abundant shredder taxa characterized the macroinvertebrate assemblage. In contrast, abundant burrower taxa characterized the macroinvertebrate assemblage in the DF stream. These results imply that Japanese cedar litter functions in structuring the macroinvertebrate assemblage by supplying persistent food resources for detritivores, and by buffering fine sedimentation via overland flow under excessive deer browsing. © 2012 The Japanese Forest Society and Springer.

Over the past decade, the abundance of sika deer has rapidly increased around Japan. Previous studies have showed overabundance of deer causes drastic reduction of forest understory vegetation, leading excessive soil erosion. However, no study has investigated the effects of excessive deer browsing on aquatic insect assemblages via sediment runoff. These effects are important to understand whether the terrestrial alteration by deer influences aquatic ecosystems. In a primary deciduous forest catchment in Ashiu, Kyoto, a deer exclusion fence has been in place since 2006. We compared forest floor cover, overland flow, stream environment, and aquatic insect assemblages in first-order streams and catchments inside and outside of the deer-exclosure from May-2008 to April-2009. The floor inside the deer-exclosure catchment was covered by lush understory vegetation, whereas outside was almost bare. The overland flow runoff rate at midslope and the dominancy of fine sediment deposition in the streambed were higher outside than inside. Among aquatic insects, burrowers, which are tolerant against fine sediment deposition, were significantly more abundant outside than inside, whereas clingers exhibited the opposite patterns. Collector-gatherers, which feed on fine detritus, were significantly more abundant outside than inside. Meanwhile, filterers were more abundant inside. The Simpson's diversity index of the aquatic insect assemblages was higher inside than outside. These results suggest that the demise of understory vegetation due to excessive deer browsing has indirectly caused changes in the aquatic insect assemblages of this catchment via increased sediment runoff and subsequent sandy sedimentation of the streambed. © 2011 The Society of Population Ecology and Springer.

To measure night visual function of glaucoma patients with good photopic vision.Patients aged 30-59 years who were diagnosed with glaucoma in the outpatient clinic of Nara Medical University, and showed a corrected visual acuity of > or = 1.0 in both eyes. The patients were classified using static threshold perimetry with a Humphrey field analyzer into two groups, with a mean deviation of -6 dB or better (early-stage glaucoma group) or a mean deviation worse than -6dB (intermediate/late-stage glaucoma group), and night visual function was measured. In addition, the patients were compared with normal controls without eye disease other than refractive error.The early-stage glaucoma group included 26 patients, and the intermediate/late-stage glaucoma group included 22 patients. There were 23 controls. Night visual function differed among the 3 groups. With the progression of visual field defects, the night visual function decreased.These results suggest that night visual function can be used as a new parameter for the evaluation of visual function in glaucoma patients.

The purpose of this research was to examine the relationship between athletic events and effect on the contents of the athletes' fashion. Investigation for 196 university students was conducted. As a result, three factors ("score", "time" and "artistry") were extracted by factor analysis based on criteria of judgment in athlete. And also three factors ("effect on oneself", "effect on an opponent", and "effect on a referee") were extracted by factor analysis of the effect on the contents of the clothing. As the independent variables, "clothing in the game" and "club affiliation", the differences of each factor were examined by analysis of variance. And the relationship between each factor was examined by canonical correlation analysis. It was found that the correlation of consciousness of "artistry in athlete" and "effect on the referee" was strong. It was suggested that the games based on the judging criteria of "time and a score" were strongly correlated with the consciousness of "effect on oneself" and "effect on an opponent". In addition, the effect of "competition wear" in the competition of club affiliation student was examined. As a result, it was suggested that it is aware to be somewhat effective in victory regardless of sporting events. ©2014 Jpn. Res. Assn. Text. End-Uses.

A Japanese-style diet consists of meals that include grain (shushoku), fish and meat (shusai), and vegetable dishes (fukusai). Little is known about the association of such meals (designated well-balanced meals hereafter) with nutrient intake. We therefore examined the frequency of well-balanced meals required to prevent nutrient deficiency. Participants were Japanese people, ages 40 to 59 y, from Toyama, recruited for INTERMAP, in an international population-based study. Each person provided 4 in-depth 24-h dietary recalls (149 men, 150 women). The prevalence of risk ratios of not meeting the Dietary Reference Intakes for Japanese (2015) was calculated. Well-balanced diets were assessed by the Japanese Food Guide Spinning Top. We counted the frequencies of meals in which participants consumed 1.0 or more servings of all 3 dishes categories. We divided the frequency of consumption of well-balanced meals into the following 4 groups: <1.00 time/d, 1.00-1.49 times/d, 1.50-1.74 times/d, and 1.75 times/d. Compared with participants in the highest frequency group for well-balanced meals, those who consumed well-balanced meals less than once a day had a higher risk of not meeting the adequate intake for potassium and the recommended dietary allowance for vitamin A. Those who consumed well-balanced meals on average less than 1.50 times per day had a higher risk of not meeting the recommended dietary allowance for calcium and vitamin C. Our results suggest that individuals should on average consume well-balanced meals more than 1.5 times per day to prevent calcium and vitamin C deficiencies.

In recent years, many studies have used epidemiological techniques to investigate the relationships of daily energy and nutrition intake to food intake, and to disease onset and treatment or prevention. Therefore, dietary assessments are now being used in various situations. A range of dietary assessment methods exists, and each has advantages and disadvantages. However, there is no absolute and universally applicable dietary assessment method. The most appropriate method or a combination of methods must be selected in accordance with factors such as the objective of a study and the number of subjects. Moreover, it is necessary to interpret dietary assessment results multilaterally and to grasp dietary habits, elements of a daily lifestyle environment, and physical conditions that could influence the diet.
