BACKGROUND High-speed rotational atherectomy uses a diamond-coated, elliptical burr to abrade occlusive atherosclerosis, especially noncompliant calcified plaque. METHODS AND RESULTS Intravascular ultrasound (IVUS) was used to analyze 28 patients after atherectomy. Arteries treated and imaged were left main (three), left anterior descending (12), left circumflex (five), right coronary (seven)...
hematomas were surgically treated and analyzed prospectively. Cases were classified according to the clinical conditions and computed tomography images. Results of the cases that underwent burr-hole craniostomy–irrigation (group A; n 1⁄4 35) were compared with those undergoing burr-hole craniostomy–closed system drainage (group B; n 1⁄4 35). The most frequent etiological factor was trauma in bo...
We introduce a four-parameter distribution, called the Zografos-Balakrishnan Burr XII distribution. Our purpose is to provide generalization that may be useful still more complex situations. The new distribution an interesting alternative describe income distributions and can also applied in actuarial science, finance, bioscience, telecommunications modelling lifetime data, for example. It cont...
With the development of the vacuum-tube microvoltmeter by Burr, Lane, and Nims4 and the elimination of many sources of error in the determination of bioelectric potentials, a new impetus has been given to the study of the direct current potential gradient of living organisms. Earlier investigators, as well as those of the last year or so, have assumed some causal relationship between the potent...
