Blood zinc protoporphyrin (ZPP), serum total protein (TP), and total cholesterol (TC) levels in automobile workshop workers
in relation to lead toxicity were analysed. In the present study, automobile workshop workers (healthy male workers at an
age between 28 and 35 from four major automobile workshops in Kottayam, Kerala State, India) and the control (male healthy
adults at an age between 28 and 35 residing at Aymanam, a distant village at Kottayam District, Kerala having reduced or no
chance of lead exposure) displayed significant difference in blood lead (BPb) and blood ZZP (BZPP) level. The mean value of
BPb in automobile workshop workers was 15.76±0.33 μg/dl, while in the control it was 8.20±0.15 μg/dl. In automobile workshop
workers, the mean value of BZPP was 34.2±0.62 μg/dl. The control group exhibited a mean of 11.5±0.22 μg/dl. Automobile workshop
workers exhibited significant increase in BZPP was corresponding to the increase in BPb level. The total protein levels estimated
in automobile workshop workers showed significant decrease compared to control individuals, but was within the reference range
of healthy individuals. The mean value of TP level in automobile workshop workers and control was 6.9±0.13 g/dl and 7.71±0.18
g/dl, respectively. There was no significant difference in blood haemoglobin (BHb) level among the automobile workshop workers
and control. The serum TC level in automobile workshop workers showed significant decrease compared to the control individuals,
but was with in the reference range of healthy individuals. The mean level of serum TC in automobile workshop workers was
162.00±3.44 mg/dl and the same in control was 172.86±4.32 mg/dl. The present study affirms occupational lead toxicity in automobile
workshop workers and its effect on serum protein and cholesterol levels. 相似文献

Students were linked virtually across three contexts: U.S., Malaysia, and China. Differences emerged in how student-created messages were constructed and interpreted; these impacted perceived relational affiliation. Messages constructed by students in Malaysia and China exhibited casual talk, greater self-disclosure, requests for personal information, and greater use of emoticons/emoji. Interactions were perceived as informal, friendly, and positive. U.S. students’ messages often showed institutional talk, less self-disclosure, and more attention to the instructor-assigned task. Asian-U.S. student pairs perceived their interactions as formal, less friendly, and less positive. This study shows how online technologies may be afforded and shaped by culture and interaction. 相似文献

Many mathematics teachers opt for a strictly teacher‐centred curriculum and/or instructional strategy. Given the well‐documented evidence noting the benefits of student‐centred instruction, it is easy to see that teacher‐centred learning on its own cannot best meet the needs of students. On the other hand, some teachers, aware of the importance of a student‐centred mathematics curriculum, adopt an exclusively student‐centred approach to curriculum and instruction. What is less obvious is that this approach can put some students who belong to certain ethnic groups at a disadvantage. Hence, to be more inclusive, mathematics educators need to take a balanced instructional approach. This paper outlines an inclusive instructional strategy that resembles the structure of and exemplifies the values promoted by the Aboriginal model of the Medicine Wheel. 相似文献

The authors examined the associations between observed classroom management and teacher-child relationships with individual children during kindergarten and Grade 1. We used a sample of nonstruggling and struggling readers and their teachers in rural schools in the Southeastern United States to examine whether gender and struggling reader status explained associations between classroom management and conflictual or close teacher-child relationships. After controlling for child- and teacher-level characteristics, results from multilevel model analyses indicated that stronger classroom management was significantly related to less teacher-rated conflict, but was not related to teacher-rated closeness. Gender was a significant moderator, with boys who were in classrooms with lower levels of classroom management having poorer teacher-child relationships as rated by their teachers. Struggling reader status was not a significant moderator of the association between classroom management and teacher-child relationships. 相似文献

Cardiovascular complications are the major cause of morbidity and mortality in diabetic patients. An attempt has been made
to evaluate the risk factors for coronary heart disease in type II diabetics. In the present study the levels of fasting and
postprandial plasma glucose, total cholesterol, low density lipoproteins, triglycerides were high and the levels of high density
lipoproteins were low in the type II diabetics compared to controls. The markers of free radical induced injury i.e. malondialdehyde
and nitrite/nitrate were high while total antioxidant status a marker for antioxidant protection against reactive oxygen species
was low in diabetics compared to controls. The study therefore suggests the importance of assessing these markers of oxidative
stress and antioxidant capacity along with the other routine investigations in diabetic patients for initiating antioxidant
therapy in addition to primary and secondary preventive measures to mitigate the devastating consequences of diabetes leading
to coronary heart disease. 相似文献

The present paper focuses on assessing the levels of various enzymatic and non-enzymatic antioxidants in selected berries
of Indian sub-continent viz., gooseberry, grapes, orange and tomato. This study has revealed that orange, tomato and grapes
possess predominant quantities of enzymatic antioxidants namely SOD, catalase and glutathione peroxidase respectively. The
levels of antioxidants analyzed namely reduced glutathione, vitamin C and vitamin A were maximal in grapes, orange and tomato
respectively. All the extracts of berries included in the present study inhibited iron inducedin vitro lipid peroxidation in erythrocytes, the extend of inhibition being highest for gooseberry and orange compared to tomato and
grapes which could be attributed to their in-built antioxidant system. 相似文献

Recent studies have presented evidence for the involvement of L1CAM gene mutations in various X-linked mental retardation
syndromes. The neural cell adhesion molecule, L1CAM is a transmembrane protein belonging to the super family of the immunoglobulins
that play a key role in embryonic development of the nervous system and is involved in memory and learning. No studies were
carried out from India on L1 CAM gene in X-linked mental retardation syndromes. Hence, an investigation was taken up to delineate
the role of L1CAM gene in mental retardation.
Two families (Family I and Family II) having only two members affected with mental retardation in each family were studied
for mutations in L1CAM gene. In family II, the younger sibling showed deletion involving region between the nucleotide 13,773
(intron 25) and 14,158 (intron 27) region. The mutation what we observed in younger sibling of the family II is a novel mutation
which was not hitherto reported in the world literature. 相似文献

The purpose of this paper is to track changes in students' attitudes about the utility of science over the middle and high school years using data from the Longitudinal Study of American Youth (Miller, J. D., Hoffer, T., Suchner, R. W., Brown, K. G., and Nelson, C. (1992). LSAY code book: student, parent, and teacher data for 1992 cohort two for longitudinal years one through four (1987–1991). Northern Illinois University, Illinois. Latent variable growth modeling is the technique that was used to examine the growth in students' attitudes about the utility of science. The results of the present study show that the overall trend for students' attitudes about the utility of science is positive. This means that middle and high school students have fairly positive attitudes about the usefulness of science. It is clear from the present analysis that some of the important predictors of attitudes about the utility of science include science self-concept, teacher encouragement of science, and to a lesser extent achievement motivation and science activities. The effects of the peer and parent variables were found to be quite small and statistically nonsignificant. Also it was found that the time-invariant predictors were not statistically significant. Latent variable growth modeling allows one to examine change in attitudes and also examine the effects of time-varying and time-invariant predictors. Substantive and methodological implications of this technique are also discussed. 相似文献

HER-2 is overexpressed in approximately 20–30% of invasive Breast Cancer. ECD of the HER-2 protein is frequently cleaved and
released into the circulation, where it can be detected by ELISA in up to 45% of patients with metastatic breast cancer. The
objective of our study was to compare the current methods for the detection of HER-2 protein. Tissue HER-2 levels were studied
in 100 breast cancer patients by IHC and compared with serum HER-2 levels by ELISA. IHC frequency was 29%. Serum HER-2 ECD
was positive in 42% of patients. A statistically significant correlation was observed. HER-2 detected by IHC correlates significantly
with serum HER-2 levels detected by ELISA. Thus, ELISA is a reliable and economical tool to assess the HER-2 status in tumors,
when breast tissue sample is not available. 相似文献
