Dispersion of Alpha-Nuclides during Animal Experiments

Systematic reviews of animal experiments.

There are strong scientific, ethical and legislative imperatives to replace animal experiments, rather than focusing efforts on improving them. Therefore, the Dr Hadwen Trust advocates that when systematic reviews identify weaknesses in animal experiments, the priority should be their replacement with more relevant non-animal methods. Individual researchers, universities, companies, funders and...

New thinking on animal experiments

National regulations on animal experiments vary widely between countries but growing numbers of researchers in Britain believe that the procedures are in need of an overhaul. And a new report by a group of members of Britain’s upper house of parliament, the House of Lords, advises a shakeup that both speeds up consideration of researchers’ requests but opens up public scrutiny of such work. The...

Laparoscopic Partial Hepatectomy: Animal Experiments

As a first step in firmly establishing laparoscopic hepatectomy, we introduce a porcine model of laparoscopic partial hepatectomy. This procedure has been successfully performed under the normal-pressure or low-pressure pneumoperitoneum condition supported by the full-thickness abdominal wall lifting technique. An ultrasonic dissector combined with electrocautery, newly developed by Olympus Opt...

Preliminary Numerical Experiments on Oceanic Dispersion

It was reported that after the magnitude 9.0 earthquake and resulting tsunami that occurred on March 11, 2011, some radioactive material, including iodine and cesium, was discharged into the Pacific Ocean because of the Fukushima Daiichi nuclear power plant (NPP) disaster. High concentrations of I and Cs were found in the seawater and seabed sediment along the coastline of Fukushima Prefecture....
