It is necessary to correct plumage color fading when comparing the plumage coloration of birds captured at different times during the breeding season. We proposed two methods for correcting plumage...

Airflow limitation and airway dimensions in chronic obstructive pulmonary disease. (2006)

Hasegawa, Masaru, Nasuhara, Yasuyuki, Onodera, Yuya, Makita, Hironi, Nagai, Katsura, Fuke, Satoshi, ...

Rationale: Chronic obstructive pulmonary disease (COPD) is characterized by airflow limitation caused by emphysema and/or airway narrowing. Computed tomography has been widely used to assess...

Relationship of airway dimensions with airflow limitation or lung volumes in chronic obstructive pulmonary disease (COPD) (2006)

Masaru Hasegawa, Yasuyuki Nasuhara, Yuya Onodera, Hironi Makita, Tomoko Betsuyaku

We have recently developed new software to obtain longitudinal images and accurate short axis images of airways with an inner diameter > 2 mm located anywhere in the lung, using curved multiplanar...
