Blood haemoglobin, serum iron, iron binding capacity, transferrin saturation and ferritin levels were determined in two groups of mothers as well as their cords—strict vegetarians (lactovegetarians) and non-vegetarians (omnivores), closely comparable in age, weight, parity and gestation period but differing in their diet and food habits. All these parameters, except total iron binding capacity, were found to be significantly lower in vegetarian mothers and their cords as compared to nonvegetarian mothers and their cords, respectively, despite receiving supplemental iron for six months. Further, there was a greater incidence of anemia and iron deficiency in mothers consuming only vegetarian diet. Moreover, a significant correlation existed between mother's ferritin to cord ferritin confirming that maternal iron deficiency does affect neonatal iron status. All these observations suggest that strict vegetarian mothers as well as their newborns have a greater incidence and risk of anemia and iron deficiency. 相似文献

Activities of antioxidant enzymes involved oxygen free radical metabolism in the liver and lung were investigated in 2,4, and 30 months old Wistar albino rats. The levels of SOD, GSH-Px, GSH and protein-SH were decreased whereas MDA increased, in the liver as well as the lung of the old rats (30 months old) compared to the young rats (2 and 4 months old). The data suggests that the failure of the free radical protective mechanism may be one of the important contributors to the process of ageing. 相似文献

Monitoring and Root Cause Analysis of Clinical Biochemistry Turn Around Time at an Academic Hospital

Quality can be defined as the ability of a product or service to satisfy the needs and expectations of the customer. Laboratories are more focusing on technical and analytical quality for reliability and accuracy of test results. Patients and clinicians however are interested in rapid, reliable and efficient service from laboratory. Turn around time (TAT), the timeliness with which laboratory personnel deliver test results, is one of the most noticeable signs of laboratory service and is often used as a key performance indicator of laboratory performance. This study is aims to provide clue for laboratory TAT monitoring and root cause analysis. In a 2 year period a total of 75,499 specimens of outdoor patient department were monitor, of this a total of 4,142 specimens exceeded TAT. With consistent efforts to monitor, root cause analysis and corrective measures, we are able to decreased the specimens exceeding TAT from 7–8 to 3.7 %. Though it is difficult task to monitor TAT with the help of laboratory information system, real time documentation and authentic data retrievable, along with identification of causes for delays and its remedial measures, improve laboratory TAT and thus patient satisfaction. 相似文献

We analyze a recently introduced approach for the sorting of aqueous drops with biological content immersed in oil, using a microfluidic chip that combines the functionality of electrowetting with the high throughput of two-phase flow microfluidics. In this electrostatic sorter, three co-planar electrodes covered by a thin dielectric layer are placed directly below the fluidic channel. Switching the potential of the central electrode creates an electrical guide that leads the drop to the desired outlet. The generated force, which deflects the drop, can be tuned via the voltage. The working principle is based on a contrast in conductivity between the drop and the continuous phase, which ensures successful operation even for drops of highly conductive biological media like phosphate buffered saline. Moreover, since the electric field does not penetrate the drop, its content is protected from electrical currents and Joule heating. A simple capacitive model allows quantitative prediction of the electrostatic forces exerted on drops. The maximum achievable sorting rate is determined by a competition between electrostatic and hydrodynamic forces. Sorting speeds up to 1200 per second are demonstrated for conductive drops of 160 pl in low viscosity oil. 相似文献

The introduction of educational standards in Germany forced teachers to change their perspective in order to achieve competence-oriented teaching. The initial representative surveys throughout Germany indicated that a short time after the introduction of the educational standards, teachers in various school forms were still very slow to implement the idea of competence-oriented teaching in their everyday school life. This article presents the effects of a newly developed intervention programme in which mathematics teachers familiarised themselves with educational standards for the first time. The teacher data and the performance data of the pupils of the schools participating in the project are compared in a longitudinal study with the data of schools which were not included in the intervention programme. The results indicate that after the intervention programme has run for one year, mathematics teachers in the project schools are more competence-oriented in their teaching and reflect more intensively on the concept of the educational standards than mathematics teachers in the comparison schools. 相似文献

The modeling of understanding consumers buying behavior requires a technique, which does not only incorporate the preferences of the consumers but also have the ability to trade-off between multi-characteristics products and services. This study is supported by evaluating a framework via a marketing research technique of Conjoint Analysis wherein we have shown how certain attributes of mobile phones when studied jointly can affect the overall buying behavior of the youth towards various brands taken into consideration. Further, customers' choice probabilities of the mobile phones, based on preferences have been evaluated and potential market size is determined. Also, this study has determined and forecasted the sales on the basis of choice probability and utility obtained via conjoint analysis. Customers of the mobile phone located in Delhi have been targeted for this study. 相似文献

The purpose of this study was to evaluate the relationship between the physicochemical properties of saliva such as flow rate,
pH, buffering capacity, calcium level, total protein and total antioxidant levels in caries free and caries active children.
The present study included one hundred and twenty healthy children who were divided into two groups; group I and group II
comprising of age groups 7–10 and 11–14 years, respectively. Both the groups were then sub-divided equally according to gender.
They were further divided into caries free and caries active with 15 children in each group. Unstimulated saliva was collected
by suction method and flow rates were determined. The samples were then analyzed for pH, buffering capacity, total protein,
calcium and total antioxidant capacity. The data was statistically analyzed using student t test (unpaired). The results revealed that when all these parameters were compared among the caries free and caries active
children, flow rate, pH, buffering capacity were slightly reduced in caries active children, but total protein and total antioxidant
capacity of saliva increased significantly in caries active children and the total calcium decreased significantly in caries
active children. Within the limitation of this study, we conclude that, the physicochemical properties of saliva play a major
role in the development of caries. 相似文献
