The Regional Cooperative Agreement (RCA) in the Asia Pacific region is one of the cooperative agreements under the aegis of the International Atomic Energy Agency and currently consists of 17 Member States. Since the region covered by the RCA is undergoing a rapid expansion in nuclear power development, many activities have been carried out under the RCA. The Electronic Networking and Outreach ...

Ribulose-1,5-bisphosphate carboxylase/oxygenase activase (RCA) is a nuclear gene that encodes a chloroplast protein that plays an important role in photosynthesis. Some reports have indicated that it may play a role in acclimation to different abiotic stresses. In this paper, we analyzed the stress-responsive elements in the 2.0 kb 5'-upstream regions of the RCA gene promoter and the primary, s...

BACKGROUND AND AIMS Formation of root cortical aerenchyma (RCA) can be induced by nutrient deficiency. In species adapted to aerobic soil conditions, this response is adaptive by reducing root maintenance requirements, thereby permitting greater soil exploration. One trade-off of RCA formation may be reduced radial transport of nutrients due to reduction in living cortical tissue. To test this ...

BACKGROUND We sought to determine the difference in the localization of coronary artery disease (CAD) between the left and right coronary artery system and investigate the effect of sex and age on that difference. METHODS We retrospectively analyzed 17,323 consecutive angiographies from January 1st, 1984 to December 31st, 2003. The demographic parameters, in particular age and sex of the inve...

Suboptimal nitrogen (N) availability is a primary constraint for crop production in developing nations, while in rich nations, intensive N fertilization carries substantial environmental and economic costs. Therefore, understanding root phenes that enhance N acquisition is of considerable importance. Structural-functional modeling predicts that root cortical aerenchyma (RCA) could improve N acq...

Recycled concrete aggregate (RCA) is a relatively new construction material, whose applications can replace natural aggregates. To do so, extensive studies on its mechanical behavior and deformation characteristics are still necessary. RCA is currently used as a subbase material in the construction of roads, which are subject to high settlements due to traffic loading. The deformation character...

Rolling circle amplification (RCA) catalyzed by φ29 DNA polymerase offers a simple method for DNA amplification in the presence of a circular DNA template and its complimentary primer. RCA continuously produces long single-strand DNA using the strand displacement activity of polymerase during DNA synthesis. This property allows one to monitor the progress of a reaction by means of electrophores...

Coronary artery anomalies are uncommon and often asymptomatic. A double right coronary artery (RCA) is an extremely rare coronary artery anomaly, and only a few cases of double RCA have been reported. We report on an atherosclerotic double RCA that appeared after primary percutaneous intervention in a patient with an acute inferior myocardial infarction. This is the second case in the literatur...
