An Overview of Hydrogen Sulfide Suicides in Yamagata Prefecture, Japan

Background: Hydrogen sulfide (H2S) is one of the major toxic gases and the second most common cause of death in workplaces among toxic gas-related morbidities. H2S suicides using hospital-based data were studied in 2008. However, most cases did not involve ambulance transfer to the hospital because the victims of H2S suicide were usually found dead at the scene. H2S suicide-related data elucida...

Studies on X-ray Effects

These experiments indicate that the direct action of x-rays in more powerful doses than can be applied therapeutically is somewhat injurious to tumor cells, but by no means destroys them. Experiment 1 also indicates that the cancer cells establish a resistance to the x-rays after repeated doses. This harmonizes with the experience of clinicians who have succeeded in checking cancerous growths f...

X-ray Diffraction Studies on Crystalline Complexes

Complexes of the gene 5 protein with a variety of oligodeoxynucleotides, ranging in length from two to eight and having several different sequences, have been formed and crystallized for x-ray diffraction analysis. The crystallographic parameters of four different unit cells, all of which are based on hexagonal packing arrangements, indicate that the fundamental unit of the complex is composed ...

X-ray Diffraction Studies on Frog Muscles

1. X-ray diffraction studies of sartorius muscles of Rana pipiens were made in a new x-ray diffraction camera which permits exposures of 3 to 6 minutes. The object-film distance can be varied from 20 to 80 mm; the muscle inside the camera can be electrically stimulated while contracting isotonically or isometrically, and can be observed by a special device. After exposures up to 30 minutes (app...
