Nasal Corynebacterium depletion is associated with polysensitization to inhalant allergens in adults

Kyouhei Koyama, Masanori Kidoguchi, Naoto Adachi, Rieko Ii et autres

BACKGROUND: Polysensitization to inhalant allergens is an important determinant of disease progression and severity in allergic conditions. Although microbial dysbiosis has been implicated in various allergic conditions, the association between nasal microbiome composition and polysensitization remains unclear. This study aimed to investigate …

An extinction of the conductive electrons of fullerene nano whisker as the air exposure effects

Tatsuya Doi, Kyouhei Koyama, Nobuyuki Aoki, F. Bird et autres

ESR spectra of fullerene nano-whiskers (FNW) are investigated to elucidate their electronic properties and the influence of oxygen absorption. A singlet ESR spectrum appears together with temperature independent Pauli-para type behavior in the area intensity (which indicates the magnetic susceptibility (χESR)) in …

Charge carrier behavior in UV irradiated fullerene nano whiskers based on studies of electrical conduction and ESR

Tatsuya Doi, Kyouhei Koyama, F. Bird, Nobuyuki Aoki et autres

The UV light irradiation to C60 fullerene induces [2+2] cyclo‐additional reaction, and creates inter‐molecule bonds between C60 molecules. That reaction makes fullerene polymer from molecules. A fine crystalline wire structure consisting of C60 molecules is called a fullerene nano whisker (FNW), and …

Electron Transport Properties in Photo and Supersonic Wave Irradiated C60 Fullerene Nano-Whisker Field-Effect Transistors

Tatsuya Doi, Kyouhei Koyama, Yasuto Chiba, H Tsuji et autres

We have investigated the irradiation effect of ultraviolet light (UV) and supersonic wave (SW) into fullerene nano-whisker (FNW) field-effect transistors (FET). FNW has been fabricated by liquid/liquid interfacial precipitation using a system of C60-saturated m-xylene and isopropyl alcohol. And the morphology of …
