Abacus-based mental calculation (AMC) is a unique strategy for arithmetic that is based on the mental abacus. AMC experts can solve calculation problems with extraordinarily fast speed and high accuracy. Previous studies have demonstrated that abacus experts showed superior performance and special neural correlates during numerical tasks. However, most of those studies focused on the perception...

BACKGROUND The performance of academic medical centers (AMCs) differs from that of other hospitals because AMCs must combine the delivery of patient care with teaching and research. PURPOSE : This study investigates the effects of strategic group membership as opposed to other structural determinants on the performance of AMCs. METHODOLOGY We used data from 24 German AMCs and applied data e...

Access to medicines is usually given under the regulatory approvals and subsequent coverage decisions, after efficacy and safety have been proven by clinical trials. Recently, systems to enable exceptional early access* have been explored to meet significant, unmet, and urgent medical needs for frontier medicines. In Japan, the Advanced Medical Care B system (AMC-B) is already in operation. Two...

results: the only significant difference was the older age of the malignant group vs. benign group (p = 0.001) regarding demographic findings. as concerns the clinical symptoms, presence of abdominal discomfort in pre-diagnosis period was the only significant parameter in malignant group (p = 0.001). additionally, data analysis of patients as a total group showed that specificity (96.4%), posit...

Melatonin inhibits tumor genesis in a variety of in vivo and in vitro experimental models of neoplasia. In industrialized societies, light at night, by suppressing melatonin production, poses a new risk for the development of a variety of cancers such as breast cancer. This effect on skin has been previously studied only in animals and not in humans. Our goal was to examine the relationship bet...
