Energized by Circulation Research over 30 years.
As a medical student of Okayama University in Japan in the early 1960s, I was very impressed by the well-designed cardiac pump function after watching and touching beating hearts in situ in canine open-chest experiments and learning about the heart in physiology classes. This definitely motivated me to learn more about cardiac function throughout my education. My dream in those days was to comb...
متن کاملDivergent Arctic-Boreal Vegetation Changes between North America and Eurasia over the Past 30 Years
Arctic-Boreal region—mainly consisting of tundra, shrub lands, and boreal forests—has been experiencing an amplified warming over the past 30 years. As the main driving force of vegetation growth in the north, temperature exhibits tight coupling with the Normalized Difference Vegetation Index (NDVI)—a proxy to photosynthetic activity. However, the comparison between North America (NA) and north...
متن کاملSeroepidemiology of Hepatitis A in Korea: Changes over the Past 30 Years
This study aimed to assess the immune status of the Korean population against hepatitis A virus (HAV). Residual serum samples from 2008 to 2010 were collected from diagnostic laboratories and a total of 1,872 samples were analyzed. Anti-HAV seroprevalence was 57.3% in subjects aged 1-4 yr, 69.8% at 5-9 yr and decreased to 38.8% at 10-14 yr, 13.0% at 15-19 yr, and 11.7% at 20-29 yr. Seroprevalen...
متن کاملChanges in surgical procedures for acromioclavicular joint dislocation over the past 30 years.
Generally, surgical treatment is recommended for Rockwood type 5 traumatic acromioclavicular joint dislocations. Since 1980, the authors have performed the modified Dewar procedure, the modified Cadenat procedure, and anatomical reconstruction of the coracoclavicular ligaments for this injury. The goal of this study was to determine the ideal surgical procedure for acromioclavicular joint dislo...
متن کاملChanges in Bird Communities in Boreal Mixedwood Forest: Harvest and Wildfire Effects over 30 Years
A current paradigm in conservation biology is that forest harvest practices that better approximate natural disturbance processes are more likely to conserve biodiversity. We contrasted bird communities in three replicate stands in each of 1, 13–15, and 22–28 yr old forests following wildfire and harvest in north-central Alberta, Canada. Stands were chosen from old (.120 yr) boreal mixedwood fo...
