A bilateral comparison of national dosimetric standards for high dose rate brachytherapy has been conducted between the Laboratoire National Henri Becquerel and the University of Wisconsin Accredited Dosimetry Calibration Laboratory. A complete overview of the methods that are currently in use to establish the two national standards is given. The comparison has been carried out using well-type transfer ionization chambers. Three units have been calibrated in both laboratories, and calibration coefficients have been compared. The discrepancies between the two measurements are within 0.3%. 相似文献

Response of cerebral blood flow to changes in carbon dioxide tension during hypothermic cardiopulmonary bypass 总被引:4,自引:0,他引:4

Changes in cerebral blood flow (CBF) in response to changes in PaCO2 were measured by intraaortic injection of 133Xe in 12 patients during hypothermic (23-30 degrees C) cardiopulmonary bypass. In each patient, CBF was determined at two randomly ordered levels of PaCO2 obtained by varying the rate of gas inflow into the pump oxygenator (Group I, n = 6) or by varying the percentage of CO2 added to the gas inflow (Group II, n = 6). Nasopharyngeal temperature, mean arterial pressure, pump-oxygenator flow, and hematocrit were maintained within a narrow range. In group I, a PaCO2 (uncorrected for body temperature) of 36 +/- 4 mmHg (mean +/- SD) was associated with a CBF of 13 +/- 5 ml X 100 g-1 X min-1, while a PaCO2 of 42 +/- 4 mmHg was associated with a CBF of 19 +/- 10 ml X 100 g-1 X min-1. In group II, a PaCO2 of 47 +/- 3 mmHg was associated with a CBF of 20 +/- 8 ml X 100 g-1 X min-1, and a PaCO2 of 53 +/- 3 mmHg was associated with a CBF of 26 +/- 9 ml X 100 g-1 X min-1. Within group I, the difference in CBF was significant (P less than 0.05); within group II, the difference in CBF was significant at the P less than 0.002 level. All CBF measurements were lower than those reported for normothermic, unanesthetized subjects of similar age.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

This study examined the stability of treatment gains after receiving self-examination therapy (SET) [Bowman, D. (1995). Innovations in clinical practice: a source book. Professional Resource Press.] for generalized anxiety disorder. A 2-year follow-up of 16 participants from Bowman, Scogin, Floyd, Patton, and Gist [J. Counsel. Psychol. 44 (1997) 267] was conducted by comparing pre- and post-treatment measures with follow-up measures from the Hamilton Anxiety Rating Scale-Revised (HARS-R), the State-Trait Anxiety Inventory (STAI), and the SET quiz. Results indicated treatment gains from baseline to the 2-year follow-up period were maintained on all measures, and there was not a significant decline from post-treatment to follow-up on the HARS-R and STAI. These results suggest that SET for treatment of generalized anxiety disorder (GAD) may be effective in both the immediate and long-term reduction of GAD symptoms. 相似文献

In an outpatient rehabilitation setting, both patients’ use and therapists’ knowledge of complementary and alternative medicine
(CAM) varies widely. Based on this observation and a recognition of CAM as an emerging practice area for rehabilitation professionals,
it was felt that a thorough and consistent approach to the education and orientation of physical therapists to the world of
CAM and integrative care was needed. This special interest paper will describe one center’s approach, development, and use
of a unique and comprehensive training manual designed to provide both a structured and standardized approach for educating
physical therapists about CAM and related therapeutic modalities. This innovative teaching tool allows for multiple methods
of content delivery within a multidisciplinary format and can be used for those who practice currently or desire to practice
in an integrative care environment. 相似文献

Glioblastoma multiforme (GBM) is the most common type of primary malignant brain tumor. Although comprehensive therapeutic measures are available, recurrence is very frequent and the prognosis of GBM remains dismal. To date, little is known about the molecular pathogenesis associated with GBM recurrence. According to Knudson ' s two-hit hypothesis of tumor suppressor gene (TSG) inactivation,1 deletion of a chromosomal region, as revealed by loss of heterozygosity (LOH), is often indicative of the presence of a potential TSG. Allelotype studies involving a comprehensive LOH analysis of the whole genome can provide more detailed and thorough information for detecting genetic anomalies than traditional LOH analysis. The present study is designed to conduct a genome-wide allelotype analysis of one patient ' s primary and corresponding recurrent GBM tumors in an effort to reveal molecular genetic alterations associated with the recurrence of this malignancy. 相似文献
