Background: Vision and hearing impairments among elders are common, and cognitive impairment is a concern. This study assessed the association of vision and hearing impairments with cognitive impairment and mortality among long-term care recipients. Methods: Data of 1754 adults aged 65 or older were included in analysis from the Gujo City Long-Term Care Insurance Database in Japan for a mean follow-up period of 4.7 years. Trained and certified investigators assessed sensory impairments and cognitive impairment using a national assessment tool. Five-level scales were used to measure vision and hearing impairments. Cognitive performance was assessed on two dimensions, namely communication/cognition and problem behaviors. We performed logistic regression analysis to estimate odd ratios (ORs) and 95 % confidence intervals (CIs) for the association of vision and hearing impairments with cognitive impairment. Using Cox proportional hazard regression models, we obtained hazard ratios (HRs) for mortality. Results: Of 1754 elders, 773 (44.0 %) had normal sensory function, 252 (14.4 %) vision impairment, 409 (23.3 %) hearing impairment, and 320 (18.2 %) dual sensory impairment. After adjusting for potential cofounders, ORs of cognitive impairment were 1.46 (95 % CI 1.07-1.98) in individuals with vision impairment, 1.47 (95 % CI 1.13-1.92) in those with hearing impairment, and 1.97 (95 % CI 1.46-2.65) in those with dual sensory impairment compared to individuals with normal sensory function. The adjusted HR of overall mortality was 1.29 (95 % CI 1.01-1.65) in individuals with dual sensory impairment and cognitive impairment relative to normal sensory and cognitive functions. Conclusions: Cognitive impairment was most common in individuals with dual sensory impairment, and those with dual sensory impairment and cognitive impairment had increased mortality. © 2016 The Author(s).

Rubidium solution was injected in the sapwood of a Japanese cedar cultivar in the growing period, and its radial movement in stem was traced to investigate the accumulation of alkali metals in the heartwood. Sapwood-injected Rb was detected in outer heartwood at 10 days after the treatment, and continued increasing at 20 days after. Radial movement of Rb toward heartwood was considered to occur soon after the treatment, and to decline at a certain point of the time after Rb injection ceased. However, Rb continued moving in heartwood probably by diffusion even after the cease of Rb injection. In a series of injection experiment, radial movement of injected Rb is not corresponding to the seasonality of both cambial activity and cytological changes of ray parenchyma accompanied with heartwood formation. From the results on Rb's behavior, we conclude that accumulation of K and other alkali metals in heartwood of Japanese cedar has two steps, active transport from sapwood to outer heartwood via ray, and diffusion in heartwood, and that these processes proceed independently from both cambial activity and cytological changes of ray parenchyma. © 2011 The Japan Wood Research Society.

Changes in the flora and the individual number of flowering plants under Sika deer browsing were investigated at Makura-dani in Ashiu Experimental Forest, Kyoto Prefecture, Japan. The number of species decreased from 84 to 56. Among the 77 species evaluated, eight species increased and 47 species decreased conspiciously in number, probably resulting in the local extinction of 22 species. The rate of species loss was greater for large-sized plants and the rate of unchanged or less changed species was greater for small-sized plants. Summer or autumn flowering herbaceous species showed higher rates of decreased species number than spring flowering species. Therefore, plant size and flowering season were the important characteristics for evaluating the browsing effect. The estimated number of flowering individuals and the Simpson's diversity index showed distinctly different phenological patterns after Shika deer browsing, and the seasonal function of flowering plant community on herbivorous insects visiting flowers were supposed to have changed.

Two activable tracers, Rb and Eu, were injected into the sapwood of Japanese cedars (Cryptomeria japonica D. Don) to investigate the radial movement of minerals in their stems in the resting period. Eight trees of four cultivars, two of which genetically form wet heartwood, were treated near the end of the growing period. At 40 days after the treatment, Rb was detected in the outer heartwood, whereas Eu was not. Radial movement of Rb was more rapid in trees with wet heartwood than in those with normal heartwood. At 204 days after the treatment, more Rb was detected in the heartwood than was found on the first sampling, whereas no Eu was detected in the heartwood. The difference in radial movement between Rb and Eu was considered mainly to be the result of selective transport of beneficial minerals by Japanese cedar. The difference in the rate of radial movement of Rb between wet and normal heartwood became more conspicuous at 204 days after treatment. We concluded that the movement of Rb from the sapwood to the outer heartwood was by active transport through the rays, whereas that in the heartwood was by diffusion due to the gradient of Rb concentration. © 2011 The Japan Wood Research Society.


The aquatic plant genus Vallisneria, which includes several invasive species, is frequently used as ornamental plants in aquaria. Naturalized populations of Vallisneria have been discovered in Japan and are believed to have escaped from aquaria. We identified these naturalized Vallisneria using the internal transcribed spacer regions of nuclear ribosomal DNA (nrITS). Two accessions of nonnative Vallisneria were determined to have invaded into Japan: one is a hybrid between Vallisneria spiralis native to Eurasia and Vallisneria denseserrulata native to China and Japan, and another is Vallisneria australis native to Australia. The invasive nature of the former accession may have resulted from hybrid vigor. We also sequenced the nrITS regions of the accessions commercially traded in Japan. The two naturalized accessions were genetically identical to two of those circulating in the Japanese market as ornamental plants for aquaria. These invasive accessions propagate vegetatively and would profoundly influence native water ecosystems in Japan. We seek to arouse attention regarding the risks posed by these invasive Vallisneria in Japan, as well as other areas. © 2015 Elsevier B.V.

Theoretical studies have predicted that reproductive interference must exclude either of the interacting species, but no testing of this prediction has ever been reported for natural populations. This study surveyed the distribution patterns of herbaceous Veronica plants, including one native and three alien species, to test whether the invasion of the alien species exerting reproductive interference excluded the native species. Results showed that the native species was repeatedly excluded from islands where an alien species invaded, exerting reproductive interference, and that other alien species had no significant effect on the native population survival. This survey also demonstrated that the native species altered its habitat from the ground to stone walls on the mainland where the alien species had been predominant. In the mainland populations, the fruit morphology differed from that of the islands, and the morphology in the mainland population seemed suitable for seed dispersion by ants at a stone wall habitat. We also surveyed the genetic differentiation among populations, the results of which did not support the native species genetically differentiated between mainland and island populations before the alien species invasion. These results strongly suggest that the reproductive interference excluded the recipient species at the population level and facilitated the habitat change. Additionally, results indicated that a series of field surveys of islands close to the mainland can be a powerful tool to test the ecological importance of reproductive interference. © 2015, The Society of Population Ecology and Springer Japan.

The concentration of phosphate in surface and oligotrophic waters is sometimes below the detection limit of conventional analytical methods. In this work, a membrane extraction method using a hydrophilic PTFE (H-PTFE) membrane filter was developed to detect trace level phosphate. Phosphoantimonyl-molybdenum blue (PAMB) was prepared under conventional conditions. The PAMB was made to react with hexadecyltrimethyl ammonium (HTMA) ions by ultrasonication in an ice bath to form an ion pair of PAMB and HTMA. The ion pair was entrapped on a H-PTFE filter by filtration, and the ion pair on the filter was extracted with CH3CN. When 10 mL of CH3CN was used as the extraction solvent for 100 mL of water sample (10 times of concentration factor), 0.80 μg PO4 L-1 (0.26 μg P L-1) was successfully detected using a conventional spectrophotometer equipped with a 5 cm cell. The total phosphorus could also be detected after oxidation with potassium peroxosulfate. © 2015 The Royal Society of Chemistry.

Although many people have expressed alarm that we are witnessing a mass extinction, few projections have been quantified, owing to limited availability of time-series data on threatened organisms, especially plants. To quantify the risk of extinction, we need to monitor changes in population size over time for as many species as possible. Here, we present the worlds first quantitative projection of plant species loss at a national level, with stochastic simulations based on the results of population censuses of 1618 threatened plant taxa in 3574 map cells of ca. 100 km2. More than 500 lay botanists helped monitor those taxa in 1994-1995 and in 2003-2004. We projected that between 370 and 561 vascular plant taxa will go extinct in Japan during the next century if past trends of population decline continue. This extinction rate is approximately two to three times the global rate. Using time-series data, we show that existing national protected areas (PAs) covering ca. 7% of Japan will not adequately prevent population declines: even core PAs can protect at best <60% of local populations from decline. Thus, the Aichi Biodiversity Target to expand PAs to 17% of land (and inland water) areas, as committed to by many national governments, is not enough: only 29.2% of currently threatened species will become non-threatened under the assumption that probability of protection success by PAs is 0.5, which our assessment shows is realistic. In countries where volunteers can be organized to monitor threatened taxa, censuses using our method should be able to quantify how fast we are losing species and to assess how effective current conservation measures such as PAs are in preventing species extinction.

In the UK and Japan, there is concern regarding rising rates of annual new HIV infections among Men who have Sex with Men (MSM). Whilst in the UK and Europe, gay businesses are increasingly recognized as being important settings through which to deliver HIV prevention and health promotion interventions to target vulnerable populations; in Japan such settings-based approaches are relatively underdeveloped. This article draws on qualitative data from a recently completed study conducted to explore whether it is feasible, acceptable and desirable to build on the recent European Everywhere project for adaptation and implementation in Japan. A series of expert workshops were conducted in Tokyo, Nagoya and Osaka with intersectoral representatives from Japanese and UK non-governmental organizations (NGOs), gay businesses, universities and gay communities (n = 46). Further discussion groups and meetings were held with NGO members and researchers from the Japanese Ministry of Health, Labour and Welfares Research Group on HIV Prevention Policy, Programme Implementation and Evaluation among MSM (n = 34). The results showed that it is desirable, feasible and acceptable to adapt and implement a Japanese version of Everywhere. Such a practical, policy-relevant, settings-based HIV prevention framework for gay businesses may help to facilitate the necessary scale up of prevention responses among MSM in Japan. Given the high degree of sexual mobility between countries in Asia, there is considerable potential for the Everywhere Project (or its Japanese variant) to be expanded and adapted to other countries within the Asia-Pacific region.
