Phytotoxic air pollutants such as atmospheric nitrogen dioxide (NO2) are among the major stresses affecting tree photosynthesis in urban areas. We clarified relationship between NO2 concentrations and photosynthetic function for three trees, Prunus × yedoensis, Rhododendron pulchrum, Ginkgo biloba, planted Kyoto surrounding cities, combining our published data new collected from 2020 to 2023. High increased long-term water use efficiency all species. decreased P. yedoensis R. while G....

Kudoid myxozoans pose serious chronic problems in marine fisheries by causing pathological damage to host fish, reducing the market value of infected fish and potentially threatening public health. Kudoa yasunagai is a cosmopolitan parasite that infects brains various fishes, including important aquaculture species. We developed quantitative PCR assay detect K. sea water, we used it monitor abundance environment culture through spring winter. Quantitative detected DNA from with lowest...

Abstract Background and Aims For a comprehensive understanding of the mechanisms changing plant photosynthetic capacity during evolutionary history, knowledge leaf gas exchange optical properties are essential, both which relate strongly to mesophyll anatomy. Although ferns suitable for investigating history capacity, research fern species has yet be undertaken in this regard. Methods We investigated properties, anatomy with wide range divergence time, using 66 from natural habitats eight...

Fast recovery from failures in a network is serious challenge. Failures are sometimes not detected because of the management system's own failure or misconfiguration by human error. Such called silent failures. Many researchers have studied failures, and much attention has been paid to developing system that detects more accurately. However, these detection methods require large amount information. Therefore, for fast recovery, point should be localized with long period first. Although using...

Abstract Many ant-aphid interactions illustrate the concept of a mutually beneficial association between two organisms: aphids provide ants with honeydew; in return, defend from enemies. However, also often prey on they attend, and we do not know if predation pressure causes any adaptations side aphids. The aphid Stomaphis japonica has an obligate mutualistic Lasius ants. Here, report evidence selective less-honeydew secreting by tending We show that 1. are severely preyed – up to half...

We studied the renal transplant blood flow using an ultrasonic contrast agent. The medium was injected intravenously and produced enhancement for at least 60 seconds. Measurements were made from recorded Doppler spectra. Fourteen recipients investigated by color echography. Blood in interlobular artery could be analyzed all patients a contrast, agent, as compared with 2 (14%) conventional method. average maximum minimum velocity of arteries 0.15 m/sec 0.04 m/sec. In conclusion, agent is...
