Fire has played an essential role in the development of human civilization. Most previous research suggests that frequent-fire regimes in the late Holocene were associated with intensification of human activities, especially agriculture development. Here, we analyze fire regimes recorded in the Song Hong delta area of…

Among 462 cases receiving coronary artery bypass graft (CABG) during the period from November 1991 to January 1999, emergency operation was performed within 24 hours for 27 cases. Male-to-female ratio was 21:6, and age of patients ranged from 50 to 83 years (average age: 65.9 years). Intra aortic balloon pumping (IABP)…

A 5-year longitudinal cohort study of the running development of Japanese adolescents was conducted at a secondary school in Tokyo from 1968 to 1994. The purpose was to investigate changes in the pattern of development over time. The test items were an endurance run (1,500 m for boys and 1,000 m for girls) and a dash (…

The last few years have withnessed the significant increase of febrile neutropenias caused by diphteroids. In fact, with the development of bacterologically protected units, saprophytic bacteria--including diphteroids 0 became increasingly important in the aethiology of febrile neutropenias. Over the period from April…

Enhanced signaling through RAS and the mitogen-associated protein kinase (MAPK) cascade underlies the RASopathies, a family of clinically related disorders affecting development and growth. In RASopathies, increased RAS-MAPK signaling can result from the upregulated activity of various RAS GTPases, enhanced function of…
