This study reports the utilization of serum fructosamine and blood glucose for the screening of gestational diabetes mellitus
(GDM). Blood samples from 165 pregnant women were analyzed for fasting blood glucose (FBG), random blood glucose (RBG) and
serum fructosamine. The actual fructosamine levels were corrected for serum protein (c-Fruct) for more precise presentation.
Two cut-off values of FBG (>5.3 mmol/L and >7.0 mmol/L) and RBG (>7.8 mmol/L and >11.0 mmol/L) were used to classify hyperglycemic
subjects for subsequent evaluation. The average values±standard deviations for FBG, RBG and cFruct were 5.865±1.95, 7.767±3.21
and 2.387±0.47 mmol/L, respectively. FBG levels were significantly correlated with RBG (Pearson correlation=0.597, P<0.001).
Significant correlations were also observed between cFruct and FBG (Pearson correlation=0.673, P<0.001) or RBG (Pearson correlation=0.641,
P<0.001). Out of 165 subjects, 24 (14.5%) cases were classified as hyperglycemic on the basis of FBG>7.0 mmol/L or RBG>11.0
mmol/L; use of lower cut-off values resulted higher frequencies of hyperglycemia. Whereas, a combined criteria of FBG>5.3
mmol/L and cFruct >2.5 mmol/L predicted 35 patients as the most probable hyperglycemic as compared to 32 patients identified
using the criteria of RBG >7.8 mmol/L and cFruct >2.5 mmol/L. These criteria were associated with 4.8% and 3.6% false-positivity
at the expense of 3.6% and 3.0% false-negative outcomes, respectively. The levels of FBG, RBG and cFruct were significantly
higher in hyperglycemic groups (irrespective of grouping criteria) as compared to the respective normal groups. In conclusion,
these findings clearly indicate that the paired values of cFruct with FBG or RBG could help in filtering high-risk individuals
for OGTT and therefore avoiding a unnecessary OGTT. 相似文献

A study of the interaction between ropranolol and NSAIDs in protein binding by gel filtration method

Drug protein binding phenomena can lead to some interesting drug—drug interactions when one drug displaces another in the
binding site. Studies of protein binding are conducted by several methods including equilibrium dialysis, ultra-filtration
and chromatographic methods. Gel filtration is a simple chromatographic method in protein binding studies. Propranolol binds
to plasma proteins by 90%–95% in circulation system and other drugs with high protein binding may displace it. In this study
protein binding of propranolol has been studied using gel filtration to Bovine Serum Albumin (BSA) alone and in the presence
of Acetyl salicylic acid (ASA), Indomethacin and mefenamic acid has been studied using gel filtration method. The results
indicated that ASA decreased protein binding of propranolol by 20% to BSA and other drugs did not displace propranolol from
the binding site. Therefore, ASA may alter pharmacological effects of propranolol. 相似文献

The effectiveness of using acoustical (sonochemical) reactor for degradation of linear alkylbenzen sulfonate (LAS) from aqueous solution was investigated. LASs are anionic surfactants,found in relatively high amounts in domestic and industrial wastewaters. In this study,experiments on LAS solution were performed using methylene blue active substances (MBAS) method. The effectiveness of acoustical processor reactor for LAS degradation is evaluated with emphasis on the effect of treatment time and initial LAS concentration. Experiments were performed at initial concentrations of 0.2,0.5,0.8 and 1.0 mg/L,acoustic fre-quency of 130 kHz,applied power of 500 W and temperature of 18 °C~20 °C. At the conditions involved,LAS degradation was found to increase with increasing sonochemical time. In addition,as the concentration increased,the LAS degradation rate de-creased in the acoustical processor reactor. 相似文献

Visual motor integration (VMI) is the ability of the eyes and hands to work together in smooth, efficient patterns. In Oman, there are few effective methods to assess VMI skills in children in inclusive settings. The current study investigated the performance of preschool and early school years responders and non-responders on a VMI test. The full range test of visual motor integration (FRTVMI) was administered to a sample of 359 children from preschool and elementary school settings in Oman. A two-way analysis of variance showed that there are statistically significant differences in VMI between preschool and early school non-responders. Gender did not show any effect on preschool children's performance on the FRTVMI, whereas it had an effect on elementary school children's performance. Results of the study are discussed in relation to the use of VMI assessment in screening for responders and non-responders in preschool and elementary school settings. Implications for psycho-educational assessment of children who struggle academically in inclusive settings are presented. 相似文献

目前亲子互动研究成为一个非常重要的课题。父母冲突作为考察亲子互动关系的一个重要变量,逐渐成为研究者关注的重要问题。尽管20世纪70年代以来,国外已从某些角度揭示了父母冲突与儿童发展的关系,并在一定程度上探讨了父母冲突对儿童的影响。但我国目前还没有系统的儿童与父母冲突的研究。因此,从我国的具体情况入手探讨亲子冲突对丰富和发展儿童心理学的基本理论,全面了解并有效促进儿童发展具有重要的理论和实践意义。 相似文献

This study investigates how portfolios support pre‐service teachers' learning to teach. The findings revealed that the portfolio provides pre‐service teachers with productive learning experiences which help them develop their library use, knowledge, skills, attitudes, personal traits, motivation to learn, interpersonal relationships and an information source. The respondents were found to consider the portfolio a highly effective tool in their learning to teach. 相似文献

In this article, attempts were made to examine students’ thinking about the concepts of infinity and their ideas about transiting from finite to infinite states through the concept of limits of sequences. The participants included 78 senior high-school students ranging in age between 17 and 19 years old. The data were collected through a questionnaire and an interview with all of the subjects. The findings showed that the students’ understanding of infinity is related to finite situations and many students consider infinite processes as a generalized form of finite processes. In the present study, the most common mistakes committed by students were related to consideration of infinity as a number and application of known finite results to infinite states. 相似文献

INTRODUCTION The simplicity and elegance of some of theapplications of graph theory to chemistry can perhapsonly be compared with the results from group theorydealing with symmetry as a basic quality of a system.In some problems connectivity and symmetry arecombined and the question of determining symmetryproperties of graph becomes important. Given here are some definitions and notations.An automorphism of a graph G is a permutation g ofthe vertex set of G with the property that, for an… 相似文献

This Regular Feature explores the role of health science librarians in the coronavirus pandemic. COVID‐19 has spread rapidly all over the world. All major cities around the globe are in lockdown. In Pakistan, the first case was diagnosed on 26 February 2020, and currently, there are more than 2039 diagnosed cases and 26 deaths as on 31 March 2020. Across the country, there are further 12 000 suspected cases. This will undoubtedly increase if precautionary measures are not taken. Pakistani universities, colleges and schools were in lockdown. The role of university librarians in this emergency included raising awareness through public health education, providing support to medical staff, researchers and providing ongoing traditional services to regular library patrons in Pakistan. The Regular Feature also provides links to useful resources. JM. 相似文献
