Three Cases of Lead Toxicity Associated with Consumption of Ayurvedic Medicines     

Raviraja A  Vishal Babu GN  Sehgal A  Saper RB  Jayawardene I  Amarasiriwardena CJ  Venkatesh T 《Indian journal of clinical biochemistry : IJCB》2010,25(3):326-329

Ayurveda is a traditional form of medicine used by majority of the Indians. Here we report three cases of lead toxicity, following intake of Ayurvedic medicines. Three patients presented with blood lead levels (BLLs) of 122.4, 115 and 42.8 μg/dl respectively at the time of hospitalization. The first case was chelated with D- penicillamine, the second with calcium disodium ethylene diamino tetra acetate (EDTA) and the third with environmental intervention and education. Associated Ayurvedic products were collected from patients and analyzed for metallic concentration. Cessation of Ayurvedic medication along with chelation, nutritional intervention and education, reduced the BLL to 27.4 μg/dl in the first case after 1 year, 21.1 μg/dl after 9 months in the second and 18.2 μg/dl after 6 months in the third case.  相似文献   

Biochemical and genetic studies on cardiometabolic syndrome     

A. Supriya Simon  D. Dinesh Roy  V. Jayapal  T. Vijayakumar 《Indian journal of clinical biochemistry : IJCB》2010,25(2):164-168

Cardiometabolic syndrome is one of the major public health issues of this century which describes a cluster of clinical characteristics. Seventy two patients with coronary artery disease (CAD) and cardiometabolic syndrome and forty healthy age and sex matched normal controls were selected for this study. Detailed clinical epidemiological and anthropometric characteristics were noted. Lipid profile and Cytokinesis-block micronuclei (CBMN) assay using cytochalasin B were carried out in all the subjects. Serum total cholesterol, triglyceride and LDL-cholesterol was significantly higher and HDL cholesterol was significantly lower in patients compared to their normal counter-parts (P<0.05). CBMN frequency of the patients was significantly higher at all ages compared to their normal counter parts (P<0.05). Various risk factors like diabetes, hypertension, dyslipidemia, abdominal obesity, smoking and alcoholism were found influenced the CBMN frequency; but the changes were not significant. From this study it can be concluded that DNA damage was found to be higher in patients with cardiometabolic syndrome which may be attributed to the generation of free radicals associated with alcohol consumption, tobacco use, dyslipidemia and glucose intolerance and the accumulation of free radicals with increase in age.  相似文献

An Automated Item Pool Assembly Framework for Maximizing Item Utilization for CAT     

Hwanggyu Lim  Kyung T. Han 《Educational Measurement》2024,43(1):39-51

Computerized adaptive testing (CAT) has gained deserved popularity in the administration of educational and professional assessments, but continues to face test security challenges. To ensure sustained quality assurance and testing integrity, it is imperative to establish and maintain multiple stable item pools that are consistent in terms of psychometric characteristics and content specifications. This study introduces the Honeycomb Pool Assembly (HPA) framework, an innovative solution for the construction of multiple parallel item pools for CAT that maximizes item utilization in the item bank. The HPA framework comprises two stages—cell assembly and pool assembly—and uses a mixed integer programming modeling approach. An empirical study demonstrated HPA's effectiveness in creating a large number of parallel pools using a real-world high-stakes CAT assessment item bank. The HPA framework offers several advantages, including (a) simultaneous creation of multiple parallel pools, (b) simplification of item pool maintenance, and (c) flexibility in establishing statistical and operational constraints. Moreover, it can help testing organizations efficiently manage and monitor the health of their item banks. Thus, the HPA framework is expected to be a valuable tool for testing professionals and organizations to address test security challenges and maintain the integrity of high-stakes CAT assessments.  相似文献

Developing experience-based (tacit) knowledge through reflection     

Cynthia T. Matthew  Robert J. Sternberg 《Learning and individual differences》2009,19(4):530-540

This investigation examined the effectiveness of reflection methods derived from Sternberg's theory of practical intelligence [Sternberg, R.J., and Hedlund, J. (2002). Practical intelligence, g, and work psychology. Human Performance 15(1/2), 143–160.; Sternberg, R.J., Forsythe, G.B., Hedlund, J., Horvath, H.A., Wagner, R.K., Williams, W.M., et al. (2000). Practical intelligence in everyday life. New York: Cambridge University Press. 2000] on the acquisition of experience-based, tacit knowledge. Two related experimental studies were conducted to test the effect of brief tacit-knowledge reflection training on practical problem solving. Reflection methods were developed based on Sternberg's conceptualized condition–action structure of tacit knowledge. In the first study, 101 U.S. Army officers participated in a reflection intervention or practice control. Results showed an effect of reflection condition on post-test tacit-knowledge scores (F [3, 91] = 3.74, p = .01, 2 = .03). In the second study, 235 college students participated in a reflection intervention or an academic-type reflection control. Results showed that the reflection condition approached significance on post-test scores (F [1, 233] = 3.47, p = .06, p = .06, 2 = .01). The investigation suggests this line of inquiry warrants continued study.  相似文献

Overshadowing and CS duration: counteraction and a reexamination of the role of within-compound associations in cue competition     

Heather T. Sissons  Gonzalo P. Urcelay  Ralph R. Miller 《Learning & behavior》2009,37(3):254-268

In the present experiments, we examined the role of within-compound associations in the interaction of the overshadowing procedure with conditioned stimulus (CS) duration, using a conditioned suppression procedure with rats. In Experiment 1, we found that, with elemental reinforced training, conditioned suppression to the target stimulus decreased as CS duration increased (i.e., the CS duration effect), whereas, with compound reinforced training (i.e., the overshadowing procedure), conditioned suppression to the target stimulus increased as CS duration increased. In subsequent experiments, we replicated these findings with sensory preconditioning and demonstrated that extinction of the overshadowing stimulus results in retrospective revaluation with short CSs and in mediated extinction with long CSs. These results highlight the role of the duration of the stimulus in behavioral control. Moreover, these results illuminate one cause (the CS duration) of whether retrospective revaluation or mediated extinction will be observed.  相似文献   

Assurance of Learning in the MIS Program     

Jeffrey S. Harper  Joseph T. Harder 《Decision Sciences Journal of Innovative Education》2009,7(2):489-504

This article describes the development of a systematic and practical methodology for assessing program effectiveness and monitoring student development in undergraduate decision sciences programs. The model we present is based on a student's progression through learning stages associated with four key competencies: technical, analytical, communicative, and managerial. Key learning activities are embedded in major courses, resulting in clear and documented demonstrated abilities from the student. The work is based upon what is formally known about student outcomes assessment and input from our own Management Information Systems (MIS) program stakeholders and accrediting bodies. The results of the assurance of learning model can be, in turn, used to refine curriculum and to meet accreditation standards.  相似文献
