A strong association has been uncovered between DNA variation at the apolipoprotein B (apoB) locus (detectable with the restriction endonuclease XbaI) and apoB level. The findings are suggestive of associations also between this DNA polymorphism and total cholesterol as well as fasting triglyceride levels, confirming recent results reported by British workers. The data suggest that lipid/apolipoprotein associations with the XbaI polymorphism are primarily caused by an effect on apoB level. In the present and in a previously reported study we found a strong association between the XbaI polymorphism and the homospecific Ag antigenic variation in low density lipoprotein (LDL) which had previously exhibited associations with lipid levels. The present data indicate that the apoB/lipid associations of the Ag and XbaI polymorphisms may reflect the same phenomenon. The associations reported could reflect variation in an apoB domain close to Ag as well as to the XbaI restriction site that is of importance for lipid binding by apoB. Alternatively, the association of apoB level with the XbaI polymorphism (which reflects a silent third base mutation in a threonine codon) could reflect phenomena related to codon usage. 相似文献

We present the sonographic finding of flapping of the dissected intima inside the carotid artery in a 48‐year‐old man who suffered an acute stroke after vigorous use of a jackhammer. The dissected intima was seen to flap inside the lumen regularly and in synchrony with the vessel's pulse. There was no distal segmental stenosis. The extracranial blood flow velocities were within normal limits and transcranial Doppler examination did not reveal any velocity alteration. © 2009 Wiley Periodicals, Inc.

OBJECTIVES: Deaths from motor vehicle crashes (MVCs) have decreased significantly over the past three decades. Unfortunately, few data have been collected regarding death rates for MVCs in minority populations. The purpose of this study was to compare the death rate of whites versus Hispanics for MVCs in a rural environment. METHODS: This study examined one rural county in North Carolina from January 1, 1999, to December 31, 1999. A retrospective cohort study was performed using the North Carolina State Highway Patrol computerized database of MVCs. Data regarding the total number of MVCs, fatalities, alcohol-related deaths, seatbelt usage, and cause of the collision were analyzed for both whites and Hispanics. Census information regarding population in this region also was obtained from the U.S. Bureau of Census. Data were analyzed using a chi-square test, with an alpha value of 0.05 used to establish statistical significance. RESULTS: During the study period, whites were involved in 2,689 MVCs, compared with 158 MVCs for Hispanics. Whites were involved in ten fatal MVCs, compared with seven fatal MVCs involving Hispanics. The percent of fatal MVCs for whites was 0.3%, or 10 deaths per 2,689 MVCs. In contrast, the percent of fatal MVCs for Hispanics was 4.4%, or 7 deaths per 158 MVCs; odds ratio (OR) = 12.4, 95% CI = 4.7 to 33.1. The 2000 Census Report for Pitt County noted a white population of 81,613 and a Hispanic population of 4,216. Based on these population data, the death rate for MVCs per 100,000 population was 12.3 for whites versus 166.0 for Hispanics, OR = 13.6, 95% CI = 5.2 to 35.6. Although the cause for this disparity was not determined, previous studies suggest that alcohol and decreased seatbelt usage are contributing factors. CONCLUSIONS: In this study, the death rates among Hispanics for rural MVCs were significantly higher than for whites. The causes of this disparity are not clear but are important to define. Only by understanding this disparity can we begin to develop appropriate interventions that may prevent these deaths. 相似文献

The status of the Beck inventories (BDI,BAI) in psychology training and practice: A major shift in clinical acceptance 下载免费PDF全文
While the Beck Depression Inventory I and II (hereon BDI) have been a mainstay in mental health assessment for many decades, a cursory review of survey‐based “test use” studies in the 1990s finds that the Beck Anxiety Inventory (BAI) was not initially a highly ranked test in the assessment of anxiety or psychopathology. To date, a review of the extant literature on the popularity of the Beck inventories in professional psychology training or practice settings has not been systematically analyzed, although Piotrowski and Gallant (Journal of Instructional Psychology, 36, 2009, 84) found the BAI the most visible anxiety scale in the research literature between 2000 and 2005. Yet, quite evident, the field of clinical assessment remains highly competitive with a proliferation of mental health scales and measures introduced, perennially, in both the professional and research literature. In addition, since the mid‐1990s, regulatory restrictions (i.e., managed care directives) on the feasibility of providing multimethod assessment services has also been a potent headwind in professional practice. Thus, historically, the professional acceptance of the BDI and BAI remains somewhat opaque, in terms of degree of usage in both training and practice settings compared to other assessment instruments. Hence, the aim of the current study is to address this gap in the literature. To that end, the author identified, through an extensive literature review, survey‐based studies with regard to personality assessment that reported on graduate‐level training in psychological testing and test usage patterns from 1989–2017. This systematic search yielded 45 articles (including 1 dissertation study) which served as the data pool for the current review (Training settings, n = 10; Practice settings, n = 35). The analysis found that the BDI has been relied upon to at least a moderate degree in 21 of the 35 (60%) of the surveys of practice settings and in 7 of the 10 (70%) of the studies of academic/internship training. Although the BAI has not been as popular as the BDI historically, this review clearly indicated that since 2010, the BAI has made a pivotal shift toward professional acceptance in practice, generated much enthusiasm in internship training, and been embraced by clinical faculty. Reflecting this emergent popularity of the Beck inventories, the current review indicated that, overall, 10 of the 14 studies (71%) since 2010 reported that both the BDI/BAI have been: (a) recognized and relied upon to a high degree in both assessment training and practice, (b) a valuable clinical tool for mental health clinicians, and (c) considered the instruments of choice amongst the myriad of brief, self‐report measures in the assessment of mood disorders. Potential competing factors, such as other established and newly introduced measures of anxiety and depression (e.g., GAD‐7, PROMIS, PHQ, DASS‐21) that may impact future trends regarding usage of the Beck inventories, were discussed. Furthermore, research efforts should investigate the common factor of negative affectivity reflected in the Beck inventories when differentiating depression and anxiety states in monitoring treatment outcomes. 相似文献
