Journal ArticleDOI
Streptozotocin and alloxan induce DNA strand breaks and poly(ADP-ribose) synthetase in pancreatic islets.
TL;DR: It is described that both Streptozotocin and alloxan cause DNA strand breaks which stimulate nuclear poly(ADP–ribose) synthetase, thereby depleting intracellular NAD and inhibiting proinsulin synthesis in isolated pancreatic islets of rats.
Journal ArticleDOI
Highly mobile gapless excitations in a two-dimensional candidate quantum spin liquid.
Minoru Yamashita,Norihito Nakata,Y. Senshu,Masaki Nagata,Hiroshi Yamamoto,Reizo Kato,Takasada Shibauchi,Yuji Matsuda +7 more
TL;DR: The thermal conductivity of a recently identified candidate quantum spin liquid candidate, the organic insulator EtMe3Sb[Pd(dmit)2]2, is measured, indicating the presence of gapless excitations with an extremely long mean free path, analogous to excitations near the Fermi surface in pure metals.
Journal ArticleDOI
High preoperative neutrophil-lymphocyte ratio predicts poor survival in patients with gastric cancer
Hideaki Shimada,Nobuhiro Takiguchi,Osamu Kainuma,Hiroaki Soda,Atsushi Ikeda,Akihiro Cho,Akinari Miyazaki,Hisashi Gunji,Hiroshi Yamamoto,Matsuo Nagata +9 more
TL;DR: A high preoperative NLR may be a convenient biomarker to identify patients with a poor prognosis after resection for primary gastric cancer, and was an independent risk factor for reduced survival on multivariate analysis.
Journal Article
Correlation between Long-Term Survival in Breast Cancer Patients and Amplification of Two Putative Oncogene-Coamplification Units: hst-1/int-2 and c-erbB-2/ear-1
Hiroyuki Tsuda,Setsuo Hirohashi,Yukio Shimosato,Teruyuki Hirota,Shoichiro Tsugane,Hiroshi Yamamoto,Nobuyuki Miyajima,Kumao Toyoshima,Tadashi Yamamoto,Jun Yokota +9 more
TL;DR: Cox's life-table regression analysis showed that amplification of c-erbB-2 had a prognostic value, which was independent of other known prognostic factors such as lymph node status and tumor size.
Journal ArticleDOI
Effects of obstructive sleep apnea on circulating ICAM-1, IL-8, and MCP-1
TL;DR: It is observed that nCPAP decreased apnea, desaturation, and the circulating ICAM-1 and IL-8 levels in OSAS patients, and observations suggest that n CPAP therapy could reduce OSAS-induced hypoxia and generation of inflammatory mediators.
