A new method for assessing lung tumor motion in radiotherapy using dynamic chest radiography.

Dynamic chest radiography (DCR) is a recent advanced modality to acquire dynamic and functional images. We developed a new method using DCR and the free analysis software, Kinovea, to assess lung tumor motion. This study aimed to demonstrate the usefulness of our method.

Tele-control of an endoscopic surgical robot system between Japan and Thailand for tele-NOTES.

We describe our experience of the development of a endoscopic surgical robot system that can penetrate into the body through the esophagus and perform surgeries in the upper gastric tubes and several organs in the abdominal cavity. In this paper, we describe the results of an experiment using this robot. We describe the configuration of the control system using a gigabit ethernet system named JGN2 for the endoscopic surgical robot.

Photoperiodic changes in hypothalamic insulin receptor gene expression are regulated by gonadal testosterone.

In order to adapt to seasonal changes, animals exhibit robust changes in their reproductive status, body weight, and molt. However, the molecular mechanisms regulating such seasonal changes in physiology and behavior are not fully understood. Here, we report the photoperiodic regulation of the insulin receptor (IR) gene in the infundibular nucleus (anatomically homologous to the mammalian arcuate nucleus) of the Japanese quail.
