The electrocardiogram is a recording of the electrical activity of the heart as it undergoes excitation (depolarization) and recovery (polarization) to initiate each beat of the heart. This electrical activity is represented by a tracing showing the various phases of the activity above or below ...
Here, using massively parallel single-cell RNA-sequencing (scRNAseq) of glioblastoma and the normal developing human brain, we discovered a conserved trilineage cancer hierarchy with progenitor cancer cells at the apex. We found that this progenitor population contains the majority of the cancer’s ...
Enter the following command to verify the status and location of the subsystem cards: rept-stat-mps Verify the SCCP card(s) reset in 2 are IS-NR. If not, reseat the card(s). If any card(s) remain OOS-MT, replace the card(s). Refer to the Maintenance Manual for card remov...
(Fig.6a-c), taking into consideration the location of each individual lesion in healthy animals. A power function33was fitted to the LET as a function of the number of trains for all three evaluation time points (Fig.6a-c). The median LET for the 24 h time point was lower than for ...
exactly with the infarct location, giving rise to a small active stress in some apical segments due to normal myocardium also being present. The compressible model required a relatively small adjustment in contraction force in the remaining healthy myocardium to compensate for loss of contractility in...
It seemed that the heart could not have escaped.No apex beat was visible, and to my surprise none could be felt, nor could any sound be heard in the usual locality. Percussion gave moderately dull note at the fifth rib, passing into dulness lower down and continuing the costal margin....

WHEN a patient complains of pain in the chest two separate questions often need to be answered. The first involves a decision as to whether or not the pain results from disturbances of the coronary circulation. The second question, which arises only when the first is answered in the negative...
