The purpose of this study was to assess the predictive values of central obesity and hyperandrogenemia in development of insulin resistance and dyslipidemia in the polycystic ovarian syndrome (PCOS) patients in our region. Differences of fasting blood glucose level, insulin resistance index HOMA-IR, lipid parameters, waist hip ratio (WHR), body mass index, LH/FSH ratio and testosterone levels between 45 PCOS cases and 35 age matched controls were obtained. Strength of association between different parameters in the case group was assayed by Pearson’s correlation analysis. Dependence of insulin resistance and WHR on different predictors was assessed by multiple linear regression assay. Total cholesterol, LDL cholesterol, LH, FSH, LH/FSH ratio, WHR and insulin resistance were significantly higher in the case group (p < 0.05). Serum testosterone showed strong correlation with insulin resistance and LH/FSH ratio (r = 0.432 and 0.747, p = 0.01 and 0.001 respectively) in the PCOS patients while WHR and serum testosterone level stood out to be most significant predictors for the insulin resistance (β = 0.361 and 0.498; p = 0.048 and 0.049 respectively). Hyperandrogenemia and central obesity were the major factors predicting development of insulin resistance and its related metabolic and cardiovascular complications in our PCOS patients. We suggest early monitoring for androgen level and WHR in these patients for predicting an ensuing insulin resistance and modulating the treatment procedure accordingly to minimise future cardiovascular risks. 相似文献

Engineering design thinking is hard to teach and still harder to learn by novices primarily due to the undetermined nature of engineering problems that often results in multiple solutions. In this paper, we investigate the effect of teaching engineering design thinking to freshmen students by using a computer-aided Design (CAD) simulation software. We present a framework for characterizing different levels of engineering design thinking displayed by students who interacted with the CAD simulation software in the context of a collaborative assignment. This framework describes the presence of four levels of engineering design thinking—beginning designer, adept beginning designer, informed designer, adept informed designer. We present the characteristics associated with each of these four levels as they pertain to four engineering design strategies that students pursued in this study—understanding the design challenge, building knowledge, weighing options and making tradeoffs, and reflecting on the process. Students demonstrated significant improvements in two strategies—understanding the design challenge and building knowledge. We discuss the affordances of the CAD simulation tool along with the learning environment that potentially helped students move towards Adept informed designers while pursuing these design strategies. 相似文献

Mucoproteins are normal and essential constituents of different types of cells, tissues, and organs in our body. Interestingly,
an increase in the serum mucoprotein has been described in several malignant disorders in various studies. To study this in
the cases of hepatocellular carcinoma thirty five patients suffering from histologically or cytologically confirmed hepatocellular
carcinoma were tested for serum mucoprotein in the Department of Biochemistry and the Department of Pathology of North Bengal
Medical College for a period of one and a half years against matched healthy controls. The serum mucoprotein was found to
be increased significantly in the cases suffering from hepatocellular carcinoma (p<0.001). So, the present study suggests
a strong correlation between the mucoprotein level and carcinomatous changes in the hepatocellular tissues. 相似文献

Wilson’s disease is a disease of abnormal copper metabolism in which free serum copper level is raised. The objective of the study was to determine, whether in Wilson disease, l-cysteine/l-cystine influx into RBC was decreased or not and the specific amino acid transporter affected by copper in normal human RBC. For l-cysteine/l-cystine influx, ten untreated cases, ten treated cases and ten age and sex matched healthy controls were recruited. To study the effect of copper on l-cysteine/l-cystine influx in RBC, 15 healthy subjects were selected. RBC GSH and l-cysteine/l-cystine influx were estimated by Beautler’s and Yildiz’s method respectively. In untreated cases, l-cysteine/l-cystine influx and erythrocyte GSH level were decreased showing that elevated level of free copper in serum or media decreased l-cysteine/l-cystine influx in human RBC. Copper treatment inhibited L amino acid transporter in normal RBC specifically. 相似文献

Decompensation followed by death is the most serious outcome in patients suffering from cirrhosis of the liver. Alteration of trace elements may play a vital role in the process of decompensation. To examine the change in status of trace elements during the decompensation process, we analysed the zinc, copper, iron, magnesium, bilirubin and albumin levels in the serum of compensated (n = 34) and decompensated (n = 31) liver cirrhosis patients and compared them with healthy control group (n = 36) by post hoc ANOVA. We observed significant alteration in the selected micronutrients in the diseased group relative to healthy controls (P < 0.05). Moreover, mean serum zinc and iron levels were significantly lower with a higher level of serum copper in decompensated cirrhosis group than in compensated group (P < 0.05). However, no significant decrease of serum magnesium was found between the two diseased groups. Our findings imply that the trace elements like zinc, copper and iron might exert important contributory roles in decompensation process in liver cirrhosis and hence, may be utilized as important biomarkers for these patients. Furthermore, we propose that replacements of those micronutrients at an early stage can delay or prevent the severe outcomes like hepatic encephalopathy, gastrointestinal bleeding, severe jaundice or ascites in these patients. 相似文献

An imbalance in the systemic redox status leading to oxidative stress has been an important factor in development of senile
cataracts, which is reflected by an increase in serum TBARS and a decrease in plasma SOD activity. Zinc has been an important
cofactor required for structural stability of SOD. In the present study the role of serum zinc level and plasma SOD activity
was analyzed in senile cataract patients showing significant oxidative stress. Serum TBARS, plasma SOD and serum zinc level
was measured in thirty randomly selected senile cataract patients against properly matched controls. Although, the analysis
of means showed a significant increase in serum TBARS and decrease in plasma SOD and serum zinc level in cases, but plasma
SOD was found to be just significantly correlated (p=0.05) with the serum zinc only in the cases. The results of partial correlation
studies and multiple regression analysis, also, showed only a significant correlation and predictable dependence between serum
TBARS and plasma SOD, excluding any role of serum zinc level. The present study concludes that it is chiefly the plasma SOD
activity, but not the serum zinc level, that determines the proneness of the patients for development of senile cataract. 相似文献

The use of the Internet as a teaching tool continues to grow in popularity at colleges and universities. We consider, from the students’ perspective, the use of an Internet approach compared to a lecture and lab‐based approach for teaching an introductory course in statistical methods. We conducted a survey of introductory statistics students. Contradictory to what was hypothesized by the authors, they favoured keeping the lecture and lab‐based approach for teaching the class. 相似文献

Background and objectives: Pharmacists use PDAs for performing various activities related to their profession. The objective of this study was to examine pharmacists’ utilization pattern and interest in usage of personal digital assistants (PDAs) in various facets of health care. Methods: A cross‐sectional survey was conducted by distributing a pre‐validated 23‐item instrument to a convenience sample of pharmacists (n = 295) in the Houston area. Usage frequency (0 = never to 5 = frequently) and interest in future use (1 = extremely disinterested to 5 = extremely interested) of PDAs for various activities were evaluated and compared across pharmacy practice settings. Results: Most pharmacists reported maximum use of PDAs, as personal organizers (3.7 ± 1.8), in obtaining drug information (2.9 ± 1.8) and as medical calculators (2.6 ± 1.9). Similar results were obtained while evaluating interest of pharmacists who did not have PDAs and have never used PDAs for these three activities. Hospital pharmacists owned and used PDAs significantly (P < 0.05) more often than community pharmacists. Conclusions: Pharmacists used PDAs for basic functions in their profession role. Application of PDA technology in community pharmacy settings may result in its better adoption in both the settings. 相似文献
