Radiocesium mobility in different parts of the two major tree species in Fukushima

Scientific Reports, 2023
Radiocesium (137Cs) released in the Fukushima Dai-ichi Nuclear Power Plant accident is still cycling in the forest ecosystem. We examined the mobility of 137Cs in the external parts—leaves/needles, branches, and bark—of the two major tree species in ...

Location of uronic acid group in Japanese cedar and Japanese beech wood cell walls as evaluated by the influences of minerals on thermal reactivity

Journal of Wood Science, 2021
The thermal reactivities of cellulose and hemicellulose are significantly different in cell walls when compared with isolated components and differ in Japanese cedar (softwood) and Japanese beech (hardwood).

Relationship among airborne pollen, sensitization, and pollen food allergy syndrome in Asian allergic children [PDF]

PeerJ, 2022
Background Causes of pediatric pollen food allergy syndrome (PFAS) differ depending on airborne pollen levels in a particular region. We aimed to analyze airborne pollen counts, IgE sensitization rates, and PFAS incidence among children with allergies in

A novel approach of preventing Japanese cedar pollen dispersal that is the cause of Japanese cedar pollinosis (JCP) using pollen-specific fungal infection. [PDF]

PLoS ONE, 2013
In Japan, Japanese cedar pollen dispersal is one of the major causes of pollinosis. Sydowia japonica is an ascomycetous fungus that grows exclusively on the male strobili of Japanese cedar, suggesting a possible mechanism for controlling pollen dispersal.

Sublingual Immunotherapy for Japanese Cedar Pollinosis

Allergology International, 2005
The prevalence of pollinosis caused by cedar pollen has increased by 10% these ten years of 26.5% in the investigation of 2008 in Japan. The pharmacotherapy is a main treatment tool for pollinosis, and the surgical treatment is not acknowledged to the treatment of pollinosis internationally.

A Clinical Study of Japanese Cedar (Cryptomeria japonica) Pollen-Induced Asthma

Allergology International, 2008
Background: Grass and birch pollens are known to induce asthma. However there are few reports about other pollen-induced asthma. Japanese cedar is the most common allergen in rhinitis in Japan but is controversial on whether it can provoke asthma ...
