BACKGROUND Allergen specific immunotherapy is highly effective, but adverse events may occur during treatment. Peptide-based immunotherapy has been proposed as one of new strategies for reduction of allergic adverse reactions. We examined the possibility of candidate peptides for the development of peptide-based immunotherapy for Japanese cedar pollinosis. METHODS Twelve Cry j 1-specific T-ce...

Our study focused on radiocaesium (137Cs) partitioning in forests, three vegetation periods after the Fukushima Daiichi nuclear power plant accident. 137Cs distribution in forest components (organic and mineral soil layers as well as tree compartments: stem, bark, needles, branches and roots) was measured for two Japanese cedar stand ages (17 and 33 years old). The results showed that around 85...

The essential oil extracts of western juniper oil (Juniperus occidentalis) and Port-Orford-cedar oil (Chamaecyparis lawsoniana) were evaluated for possible dermal toxic effects on mice and rabbits. Mice were tested for their response to both extracts utilizing a local lymph node assay. Western juniper oil extract at 0.5% and 5% concentrations did not show a stimulation index (SI) greater than n...

Japanese cedar pollinosis is caused by exposure to Japanese cedar (Cryptomeria japonica) pollen, of which two components, Cry j 1 and Cry j 2, are believed to be the major allergens. T cell lines specific to either Cry j 1 or rCry j 2 were reactive to various portions of each panel of overlapping peptides derived from Cry j 1 or Cry j 2. Two peptides, p211-225 and p108-120, from among six major...

Gandevia, B., and Milne, J. (1970). Brit. J. industr. Med., 27, 235-244. Occupational asthma and rhinitis due to Western red cedar (Thuja plicata), with special reference to bronchial reactivity. With the increasing use of Western, or Canadian, red cedar (Thuja plicata) in the timber industry, a distinctive respiratory syndrome of rhinitis and asthma has been observed with increasing frequency ...

Stemflow from Japanese red cedar (Cryptomeria japonica) enters forest soil at a low pH. We evaluated the responses of the root system of Japanese red cedar saplings to acidic conditions, used to simulate this situation, in two different growth media, a brown forest soil (BS) and a Yahagi sand (YS). Soils were acidified by the addition of solutions at pH 2.0, 3.0 and 5.5 (control). Root morpholo...

We examined the extent of osmotic adjustment and the changes in relative water content (RWC) and transpiration rate (i.e., relative stomatal function) that occur in water-deficit-conditioned 6-year-old Thuja occidentalis L. (eastern white cedar) trees in response to a severe drought. Trees conditioned by successive cycles of mild or moderate nonlethal water stress (conditioning) and nonconditio...

Plant diseases are a severe cause of crop losses in the agriculture globally. Detection plants is difficult and challenging due to lack expert knowledge. Deep learning-based models provide promising ways identify plant using leaf images. However, need larger training sets, computational complexity, overfitting, etc. major issues with these techniques that still be addressed. In this work, convo...

Aiming to develop a new tree biomass estimation model that is adaptable airborne observations of forest canopies by unmanned aerial vehicles (UAVs), we applied two theories plant form; the pipe theory (PMT) and statical form as an extension PMT for tall trees. Based on these theories, was formulated using individual canopy height derived from UAV. The advantage this it does not depend diameter ...

Needle blight, caused by Passalora sequoiae (Mycosphaerellaceae, Ascomycota), is an economically significant disease that commonly affects Japanese cedar (Cryptomeria japonica) in Japan. With the increasing production of saplings as part reforestation efforts, there concern needle blight will become more prevalent nursery fields. However, when visually inspected, this sometimes misdiagnosed oth...
