Differential Gene Expression by RNA-Seq Analysis of the Primo Vessel in the Rabbit Lymph.

For the connectome of primo vascular system, some long-type primo vessels dyed with Alcian blue injected into inguinal nodes, abdominal node, and axially nodes were visualized, which passed over around the vena cava of the rabbit. The Alcian blue dye revealed primo vessels and colored blue in the rabbit lymph vessels. The length of long-type primo vessels was 18 cm on average, of which diameters were about 20-30 μm, and the lymph vessels had diameters of 100-150 μm.

Three-dimensional conformal reirradiation for locoregionally recurrent lung cancer previously treated with radiation therapy.

Background: To evaluate the efficacy and toxicity of reirradiation using three-dimensional conformal radiotherapy (3D-CRT) in symptomatic patients with locoregionally recurrent lung cancer.

Methods: Between 2005 and 2012, 15 patients with locoregionally recurrent lung cancer were retreated with 3D-CRT after previously receiving thoracic radiotherapy. The median interval between the initial irradiation and reirradiation was 12 months (range, five to 41 months).

Reconstitution of internal target volumes by combining four-dimensional computed tomography and a modified slow computed tomography scan in stereotactic body radiotherapy planning for lung cancer.

Background: To evaluate the volumetric and geometric differences in the ITVs generated by four-dimensional (4D) computed tomography (CT), a modified slow CT scan, and a combination of these CT methods in lung cancer patients treated with stereotactic body radiotherapy (SBRT).

Methods: Both 4D CT and modified slow CT using a multi-slice CT scanner were performed for SBRT planning in 14 patients with 15 pulmonary targets. Volumetric and geometric analyses were performed for (1) ITVall, generated by combining the gross tumor volumes (GTVs) from all 8 phases of the 4D CT; (2) ITV2, generated by combining the GTVs from 2 extreme phases of the 4D CT; (3) ITVslow, derived from the GTV on the modified slow CT scan; (4) ITVall+slow, generated by combining ITVall and ITVslow; and (5) ITV2+slow, generated by combining ITV2 and ITVslow.
