Identification of Cha o 3 homolog Cry j 4 from Cryptomeria japonica (Japanese cedar) pollen: Limitation of the present Japanese cedar–specific ASIT

Allergology International, 2018
Background: About one-third of the Japanese population suffers from Japanese cedar pollinosis, which is frequently accompanied by Japanese cypress pollinosis. Recently, a novel major Japanese cypress pollen allergen, Cha o 3, was discovered.

A 13-year Study of Japanese Cedar Pollinosis in Japanese Schoolchildren

Allergology International, 2008
Japanese cedar pollen (JCP) sensitization and Japanese cedar pollinosis (JCPS) appear to be increasingly prevalent in younger children. The present study investigated factors affecting JCP sensitization and JCPS development in school children.In May or June each year from 1994 to 2006, 275-510 children were assessed for serum JCP-IgE and house dust ...

Japanese cedar pollinosis: Discovery, nomenclature, and epidemiological trends

Proceedings of the Japan Academy, Series B, 2014
The history of pollinosis in Japan before the discovery of Japanese cedar pollinosis was presented in part I in this paper. Until early 1960s, it was believed that there was no pollinosis in Japan except one case of ragweed pollinosis. The summary of how the Japanese cedar pollinosis was discovered and named was presented in part II, by referring to ...

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 ...

Effects and interaction of different interior material treatment and personal preference on psychological and physiological responses in living environment

Journal of Wood Science, 2020
Japanese cedar (Cryptomeria japonica) wood is widely used as a traditional construction material in Japan. The relationship between an individual’s perceived comfort level and a preference for Japanese cedar wood interiors is of interest.

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.
