BACKGROUND AND AIMS Root cortical aerenchyma (RCA) increases water and nutrient acquisition by reducing the metabolic costs of soil exploration. In this study the hypothesis was tested that living cortical area (LCA; transversal root cortical area minus aerenchyma area and intercellular air space) is a better predictor of root respiration, soil exploration and, therefore, drought tolerance than...

Coronary stent fracture is a known complication of coronary arterial stent placements. Multiple long-term risks are also associated with drug eluting stents. 64-slice multidetector CT (MDCT) coronary angiography has been shown to detect poststent complications such as instent stenosis, thrombosis, stent migration and stent fractures. We report a case of stent fracture in a patient who underwent...

Zygotes of the brown alga Fucus distichus L. Powell accumulate a sulfated polysaccharide (fucoidin) in the cell wall at the site of rhizoid formation. Previous work indicated that zygotes grown in seawater minus sulfate do not sulfate the preformed fucan (an unsulfated fucoidin) but form rhizoids. Under these conditions, we determined whether sulfation of the fucan is required for its localizat...

BACKGROUND Classifying the location of an occlusion in the culprit artery during ST-elevation myocardial infarction is important for risk stratification to optimize treatment. OBJECTIVES To compare the validity of echocardiographic parameters assessing right ventricular (RV) function for the prediction of proximal right coronary artery (RCA) lesion in patients with inferior wall myocardial in...

Rapid analyte measurement platform (RAMPtrade mark) fluorogenic hand-held immunoassays (HHAs) were evaluated for inclusivity/sensitivity, exclusivity/specificity, sample matrix effects, ruggedness/stability, and reproducibility in detection of ricin (RCA(60)), a potential biological threat agent. The limit of detection of HHAs for RCA(60) was 14 ng/mL or approximately 140 pg/test. HHAs were inc...

http://dx.doi.org/10.1016/j.ijcha.2014.10.005 2352-9067/© 2014 The Authors. Published by Elsevier Ireland Ltd. This is an open access articl ventricle (LV) with normal LV function. The patient was scheduled for a coronary angiogram that showed a patent left coronary artery and a complete occlusion of ostial right coronary artery (RCA). The RCA is opacified through collaterals from left coronary...

Small molecule metabolites and their allosterically regulated repressors play an important role in many gene expression and metabolic disorder processes. These natural sensors, though valuable as good logic switches, have rarely been employed without transcription machinery in cells. Here, two pairs of repressors, which function in opposite ways, were cloned, purified and used to control DNA re...

We studied the Firing Squad Synchronization Problem (FSSP) on reversible (i.e., backward deterministic) cellular automata (RCA). First we proved that, in the case of RCA, there is no solution under the usual condition for FSSP where the firing state is only one. So we defined a little weaker condition suitable for RCA in which finite number of firing states are allowed. We showed that Minsky’s ...

The anomalous origin of the right coronary artery (RCA) is a rare condition. Most RCA anomalies are usually found incidentally, but these findings have clinical significance because many patients, particularly young ones, present with sudden death, myocardial ischemia and syncope without other symptoms. We describe a case of a 39-year-old male patient that presented with effort chest pain and w...
