In the present study, the cause of suspected false-positive (anomalous) values for CK-MB activity, in Indian patients investigated
for ACS. Total serum CK and CK-MB activity, serum Troponin I were measured and CK-MB as a percentage of the total CK activity
(%CK-MB) calculated. CK-MB was also estimated using densitometry and CK-MB mass assay. Anomalous specimens were tested for
the presence of CK isoenzymes. In 22 healthy subjects, 11 male and female, the %CK-MB ranged from 3.6 to 30.2. In 11 male
patients, with proven ACS, the %CK-MB was from 4.0 to 17.5. The cut off for anomalous CK-MB activity values was set as >33.0%.
In 35 patients with anomalies, total CK values ranged from 39 to 231 U/L, CK-MB from 30 to 161 U/L. Investigation of CK isoenzymes,
showed 10 patients had a CK-BB band, 14 an intermediate band between CK-MM and CK-MB (macro-CK type 1), 7 had a cathodal band
(macro-CK type 2), and 3 had a band intermediate between CK-MB and CK-BB. This later band does not seem to have been previously
reported. Against the CK-MB mass assay, the activity assay showed no correlation, in 43 patients (19 M, 24 F), Pearson coefficient
(R2) was 0.006. The CK-MB immunoinhibition assay is better described as measuring “non-CK-MM activity.” A %CK-MB activity >6%
as a marker of ACS is not valid in our patient population. Laboratories should not use only CK-MB activity as a biochemical
marker of ACS. 相似文献

This essay explores the growth of boxing among the African populations on the Witwatersrand region of South Africa between 1924 and 1959. It details how the sport's jump in popularity with Africans paralleled migration to Johannesburg. Africans increasingly saw boxing as an activity and skill conducive with survival in this new environment, and thus the sport grew in popularity, stature, and skill-level amongst this emergent urban population. The essay further explores the various ways that the sport was disseminated and popularized during the era, thus detailing how the sport reached both the African masses and petit-bourgeois educated elite. As their presence in Johannesburg became more and more permanent, boxing came to encompass various meanings and ideals, such as notions of discipline, independence and civility, to these urban populations. 相似文献

Within maltreatment research, type, frequency, and severity of abuse are often confounded and not always specifically documented. The result is samples that are often heterogeneous in regard to maltreatment experience, and the role of the different components of maltreatment in predicting outcome is unclear. The purpose of the present study was to identify and test the potential unique role of type, frequency, and severity of maltreatment to elucidate each variable's role in predicting outcome behavior. Data from 309 youth in foster care (ages 8–22) and their caregivers were collected using the Modified Maltreatment Classification System and the Behavioral Assessment System for Children, 2nd Edition (BASC2), to measure maltreatment exposure and behavioral outcome respectively. A measurement model of the BASC2 was completed to determine model fit within the sample data. A second confirmatory factor analysis (CFA) was completed to determine the unique contributions of frequency and severity of maltreatment across four types of abuse to externalizing, internalizing, and adaptive behavior. The result of the CFA determined good fit of the BASC2 to the sample data after a few modifications. The result of the second CFA indicated that the paths from severity to externalizing behavior and adaptive behavior (reverse loading) were significant. Paths from frequency of abuse were not predictive of behavioral outcome. Maltreatment is a complex construct and researchers are encouraged to examine components of abuse that may be differentially related to outcome behavior for youth. Untangling the multifaceted nature of abuse is important and may have implications for identifying specific outcomes for youth exposed to maltreatment. 相似文献

This research compares the fifty top-rated movies for 2000–2009 recommended by the Internet Movie Database (IMDb) with the holdings of ten medium-sized public libraries. The study shows that there was no relation between a movie's rank in the IMDb listing and the number of copies held. Relationships appeared between number of library holdings and country of production (U.S. productions favored), genre (family, sci-fi, animation, adventure favored), and Motion Picture Association of America (MPAA) rating (G, PG, PG-13 preferred). Library holdings seem to reflect preferences of IMDb raters aged 30 and older, not popular movie tastes. 相似文献

No museum is actually “neutral,” ever. This article presents the keynote address presented at the annual conference of the International Committee on Museum Management (INTERCOM) and of the Federation of International Human Rights Museums (FIHRM). In it, the author lays out the provocative case that museums not only are not, but should not be “neutral” when it comes to issues of human rights and social justice. Museums need not present both sides of every argument, or retain a lofty academic tone when it comes to the injustices of the present and the past. As an alternative course, the author presents a framework published by the British Museums Association, entitled Museums Change Lives, which offers a vision for museums to engage with challenging topics. He then offers a series of examples where Museums have embraced a new role as a promoter of social good. 相似文献

Serum ceruloplasmin is one of the most commonly used screening tests for Wilson’s disease. However immunological assays for
ceruloplasmin are not recommended for diagnosis and management of Wilson’s disease through calculation of free copper index.
Enzymatic methods using non-physiological substrates have toxicity and stability problems, making them difficult to automate.
Ferroxidase assays may be a satisfactory alternative for measuring serum ceruloplasmin. The o-dianisidine hydrochloride manual
method for estimation of serum ceruloplasmin enzyme activity was compared with an automated method using the ferroxidase activity
of ceruloplasmin in measurement in a double blind study in 91 consecutive patients screened for Wilson’s disease. The o-dianisidine
and ferroxidase methods both successfully identified 7 patients with Wilson’s disease. Values for these 7 patients in the
o-dianisidine and ferroxidase methods were median 5.0 (range 0–16.0 U/L) and median 45.0 (range 4–166 U/L) respectively. There
were 7 other positive values (<62 U/L) with the o-diansidine method and 2 (<200 U/L) with the ferroxidase method, where WD
was not confirmed. ROC curves for both methods showed area under the curve of 0.998 for o-dianisidine and 0.997 for ferroxidase.
Using literature cut off values of 62 U/L and 200 U/L respectively both methods had 100% sensitivity and specificity was 91.7%
(o-dianisidine) and 97.6% (ferroxidase). For the o-dianisidine assay, specificity was improved to 98.8% using a cut off of
22.5 U/L. In the 84 persons (46 adults and 38 children) in whom the diagnosis of Wilson’s disease was not established, the
mean value for ceruloplasmin activity by the o-dianisidine and ferroxidase methods was 124.7 ± 48.7 U/L and 571.4 ± 168.1
U/L respectively. There were no significant differences between sex or age of patients (p > 0.29). In a subsequent evaluation
with 372 specimens, the Pearson correlation coefficient between the assays was 0.908, p < 0.01, slope 4.06, intercept 265.8,
with the manual assay as the x-axis. The ferroxidase assay is a suitable replacement for the o-dianisidine assay in detecting
patients with Wilson’s disease. 相似文献
