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.

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.

To measure night visual function of glaucoma patients with good photopic vision. SUBJECTS and 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.

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.

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.
