An innovative strategy called “progressive drawing” was used at the beginning (lid‐opener) and later (monotony‐breaker) during gross anatomy lectures. Diagrams were drawn on the classroom blackboard with anatomic structures added one by one. Students identified and labeled the diagrams and predicted the next structures to be drawn. Students felt that the strategy helped to activate prior knowledge, created interest in the current lecture, and made lecture sessions more interactive. The strategy has appeal for visual, auditory, read/write, and kinesthetic learners. Anat Sci Educ, 2010. © 2010 American Association of Anatomists. 相似文献

Objective: Fetus with intrauterine stress may exhibit programmed changes that can alter its metabolism and bear severe risk for diseases in adult life. The current study was designed to assess the correlation between cord blood lipid profile with the anthropometric data in neonates. Materials and methods: 146 newborn babies born at Dr. T M A Pai Hospital, Udupi were screened and their birth weight, length, head circumference and abdominal circumference were noted at birth. Umbilical cord blood samples were analyzed for total cholesterol, triglycerides (TG), high density lipoprotein (HDL) and low density lipoprotein (LDL). Infants were also grouped further based on gestational age (GA) and sex-adjusted birth weight percentiles into three groups i.e. Small for gestational age (SGA), Appropriate for gestational age (AGA) and Large for gestational age (LGA) for comparison of their lipid profiles. Inclusion criteria were normal fetal heart rate at birth and an APGAR score >7. Statistical significance of relation between lipid profile and anthropometry was done using ANOVA and Pearson correlation coefficient. Results: Triglycerides were significantly higher in babies with higher ponderal index (PI) than those with lower PI (P = 0.011). The TG level of SGA babies were significantly higher as compared to AGA group (P = 0.001). The LDL levels in neonates with higher abdominal circumference were significantly lower than those with lower AC (P = 0.019). Mean HDL levels were higher in neonates with larger AC, but not statistically significant. Maternal BMI had no influence on neonates’ lipid profile. Conclusion: Abnormal intrauterine milieu created by maternal changes during gestation may bear a profound impact on lipid metabolism in neonates, which may account for their differences in lipid profile and anthropometry at birth. 相似文献

A variety of laboratory tests are available to assist in the diagnosis of alcohol consumption and related disorders. The levels
of intake at which laboratory results become abnormal vary from person to person. Laboratory tests are particularly useful
in settings where cooperativeness is suspected or when a history is not available. Several biochemical and hematological tests,
such as γ-glutamyltransferase (GGT) activity, aspartate aminotransferase (AST) activity, high-density lipoprotein cholesterol
(HDL-C) content of serum, and erythrocyte mean corpuscular volume (MCV) are established markers of alcohol intake. Their validity
as markers is based largely on correlations with recent intake at a single time point and on decreases in elevated values
when heavy drinkers abstain from alcohol. These readily available laboratory tests provide important prognostic information
and should be integral part of the assessment of persons with hazardous alcohol consumption. There are several other markers
with considerable potential for more accurate reflection of recent alcohol intake. These include carbohydrate deficient transferrin,
β-hexosaminidase, acetaldehyde adducts and the urinary ratio of serotonin metabolites, 5-hydroxytryptophol and 5-hydroxyindoleacetic
acid. These markers provide hope for more sensitive and specific aids to diagnosis and improved monitoring for intake. 相似文献

Aluminum and alcohol, both are well-accepted neurotoxin. The plausible mechanisms for their neurotoxicity are also common.
Therefore, the effect of ethanol on aluminum induced biochemical changes in rat brain is being studied. In the present study,
ethanol exposure significantly affected the aluminum and protein content of brain. The activities of acid phosphatase and
alkaline phosphatase were also changed. Aluminum exposure, on the other hand, contributed significantly in the alterations
of aluminum content, acid phosphatase acivity and aspartate aminotransferase activity. Though ethanol co-exposure significantly
influenced the aluminum load of brain, the interactions of these two neurotoxins were found to be significant only in case
of acid phosphatase activity of brain. Therefore, it can be suggested that general neurotoxicity produced by aluminum is not
modified by ethanol. However, the aluminum load caused by aluminum exposure, may be influenced by ethanol co-exposure. 相似文献

Both cigarette smoking and propranolol administration significantly alter plasma lipid profile. We examined the relationship
of cigarette smoking and propranolol administration with fasting serum total cholesterol, triglyceride, lipoprotein cholesterol
subfractions (high density, low density, and very low density), Apo-A, Apo-B and ratios obtained from these variables in 42
hypertensive patients. Significantly lower values of HDL cholesterol, Apo-A and HDL-C/total cholesterol and Apo-A/Apo-B ratios
were observed in smokers taking propranolol than non-smokers not taking propranolol. Smokers who were not on propranolol also
had significantly lower values as compared to non-smokers. These findings suggest that smoking may be the more significant
factor responsible for alteration in lipid profile. 相似文献
