We propose a positron detector with 8 layers of scintillation fibers whose length is 1 m and whose diameter is 0.2 mm. The shape of this detector is like as endoscope but one layer of fibers is spirally rolled clockwise, and another layer is counter-clockwise. The pitch of inner and outer spiral fibers are 85 and 75mm, respectively. This detector can be installed into the intestines from the anus,...
Reactivation of cytomegalovirus (CMV) in the bloodstream may occur upon severe immune defect or suppression during lifetime. We performed a case controlled study to probe the effects of the host cytokine gene single nucleotide polymorphisms (SNPs) on CMV reactivation. The study subjects were patients with cancer but without stem cell transplantation. The cases were patients tested positive for CMV...
Background We conducted a prospective randomized trial to compare laparoscopy-assisted distal gastrectomy (LADG) including lymphadenectomy with open distal gastrectomy for the management of early gastric cancer (EGC). Methods Forty-seven patients who had been diagnosed endoscopically with EGC were included in a study that ran from November 2001 to August 2003. With the aid of random number table,...
