Decline in radiocesium in seafloor sediments off Fukushima and nearby prefectures

Radioactivity has been monitored in seafloor sediments off Fukushima and nearby prefectures regularly. During the initial monitoring period (May–September 2011), 137Cs concentrations in the surface sediments (0–3 cm) generally increased to 8–580 Bq/kg. Subsequently, concentrations decreased at variable rates. In the latest data, from February 2016, concentrations were still...

Temporal variation of cesium isotope concentrations and atom ratios in zooplankton in the Pacific off the east coast of Japan

After the Fukushima Daiichi Nuclear Power Plant accident in March 2011, concentrations of cesium isotopes (133Cs, 134Cs, and 137Cs) were measured in zooplankton collected in the Pacific off the east coast of Japan from May 2012 to February 2015. The time series of the data exhibited sporadic 137Cs concentration peaks in zooplankton. In addition, the atom ratio of 137Cs/133Cs in...

Percutaneous transluminal renal angioplasty with stenting for stenotic venous bypass grafts: report of two cases

Cases of percutaneous transluminal renal angioplasty for renal artery stenosis are increasing. However, percutaneous transluminal renal angioplasty with stenting for stenotic venous bypass grafts has never been reported. Herein, the authors describe two cases of percutaneous transluminal renal angioplasty with stenting for a stenotic venous bypass graft. The patients in both...

Video-assisted thoracic surgery lobectomy preserves more latissimus dorsi muscle than conventional surgery☆

Video-assisted thoracic surgery (VATS) lobectomy for early lung cancer has become technically feasible. We sought to determine if VATS preserved chest wall muscle postoperatively better than thoracotomy. Consecutive patients who underwent lobectomy between 2004 and 2006 for clinical Stage IA non-small cell lung cancer through VATS (VATS group) or posterolateral thoracotomy (PLT...
