Initial experience of virtual-assisted lung mapping utilizing both indocyanine green and indigo carmine.

Virtual-assisted lung mapping is a bronchoscopic multiple dye marking technique that facilitates sublobar lung resections for unidentifiable pulmonary tumors. Marking failure reportedly occurs in 10% of cases. To overcome this limitation, we developed indocyanine green virtual-assisted lung mapping that uses indocyanine green in addition to indigo carmine.

Emergency left pneumonectomy for foreign body aspiration: a case report.

Bronchoscopic extraction is the most common treatment of foreign body aspiration. However, surgical interventions are required in cases wherein bronchoscopic extraction is difficult, with the most frequent surgical strategy being bronchotomy or lobectomy. Herein, we report a case of foreign body aspiration wherein left pneumonectomy was inevitable because of a molar incarcerated in the left main bronchus.

Areolae of the placenta in the Antarctic minke whale (Balaenoptera bonaerensis).

In this study, we examined the existence and structure of areolae and the steroidogenesis of areolar trophoblast cells in the Antarctic minke whale placenta morphologically and immunohistochemically. Placentas were collected from the 15th, 16th and 18th Japanese Whale Research Program under Special Permit in the Antarctic (JARPA) and 1st JARPA II organized by the Institute of Cetacean Research in Tokyo, Japan. The opening and cavity of fetal areolae formed by taller columnar trophoblast cells (areolar trophoblast cells) with long microvilli and a bright cytoplasm, as compared with the trophoblast cells of the chorionic villi interdigitating with the endometrial crypts, were recognized in observations of serial sections.

Structure and steroidogenesis of the placenta in the Antarctic minke whale (Balaenoptera bonaerensis).

There are few reports describing the structure and function of the whale placenta with the advance of pregnancy. In this study, therefore, the placenta and nonpregnant uterus of the Antarctic minke whale were observed morphologically and immunohistochemically. Placentas and nonpregnant uteri were collected from the 15th, 16th and 18th Japanese Whale Research Programme with Special Permit in the Antarctic (JARPA) and 1st JARPA II organized by the Institute of Cetacean Research in Tokyo, Japan.
