Increase in urine albumin excretion rate (AER) precede a fall in glomerular
filtration rate in patients developing diabetic chronic kidney disease (CKD). Our
results have shown that 7 (50 %) of diabetic and hypertensive individuals with
decreased GFR do not have increased AER. In this cross-sectional study, we measured
AER of 75 patients with type 2 diabetes and hypertension by immunoturbidimetric
method. We correlated the results with eGFR values obtained by Cockcroft–Gault and
MDRD method. The method used was not a compensated method. We measured serum
creatinine by modified Jaffe’s kinetic method in autoanalyzer XL-600. Analysis of
data showed positive correlation between eGFR and microalbuminuria by both the
methods with eGFR <60 mL/min/1.73 m2. Pearson’s
correlation co-efficient (r) was 0.9 (p = 0.0001)
by Cockcroft–Gault formula and 0.69 (p = 0.0063)
by MDRD formula. Our results concluded that there was positive correlation between
AER and eGFR <60 mL/min/1.73 m2. We have recognized
that these two parameters provide a complimentary benefit in management of cases
with CKD. 相似文献

Urban children all over the world seem to acquire computing skills without adult intervention. Indeed this form of self-instruction has produced hackersÃchildren who can penetrate high tech security systems. Is this kind of learning dependent only on the availability of technology? We provided slum children in New Delhi with Internet access in their settlement. The paper describes the results obtained in the first month of unsupervised and unguided access. It is observed that children seem to understand and use the technology fluently. Language and formal education do not seem to make any significant difference. 相似文献

Little is known about host-parasite inter-relationship in the lymphatic filarial parasites. There is no information available
about the ability of these parasites to acquire cholesterol, though it is known that in general, nematodes lack the ability
to synthesise cholesterolde novo. In this study, we have shown that the filarial parasites also lack the ability to incorporate labelled acetate into cholesterol,
indicating the absence of the machinery for cholesterol biosynthesis. We have further shown that they elaborate a 43 kDa surface
receptor for acquiring LDL-bound cholesterol. We have shown by polymerase chain reaction the presence of a 860 bp fragment
indicating the presence of the gene for LDL-related protein (LRP) in the human filarial parasiteWuchereria bancrofti in the genomic DNA. We have also shown that it is expressed as seen in the cDNA clones identified from an expression library. 相似文献

Clinical reference intervals among Indian population are poorly defined. Therefore, there is an urgent need to establish local clinical laboratory reference intervals for healthy Indian population. The present study aimed to identify the 95 % reference interval for hematological and biochemical parameters in apparently healthy Indian population. We undertook a multicentric cross-sectional study conducted at Apollo Hospitals Educational and Research Foundation across India. Of which 10,665 reference individuals identified as healthy by physicians. The 95 % of the reference distribution was estimated using 2.5th and 97.5th percentile reference limits. The 95 % reference intervals for hemoglobin (Males: 12.3–17 g/dL; Females: 9.9–14.3 g/dL), platelet count (Males: 1.3–3.8; Females: 1.3–4.2 Lakhs/µL), erythrocyte sedimentation rate (Males: 2–22; Females: 4–55 mm/h), serum uric acid in males: 3.5–8.2 mg/dL, gamma glutamyl transferase (Males: 13–61 U/L), fasting blood glucose (Males: 78–110 mg/dL), total cholesterol (Males: 115–254 mg/dL), low density lipoprotein (Males: 60–176 mg/dL) and triglycerides (Males: 55–267 mg/dL, Females: 52–207 mg/dL) were different from currently used reference values. Additionally need for gender based partitioning were observed for triglycerides and gamma glutamyl transferase. The observed findings are of clinical significance and it needs to be validated with additional community based studies. 相似文献

This paper proposes a new watermarking approach using dynamic stochastic resonance (DSR) based tuning operation to extract the watermark logo from the watermarked image that has undergone different intentional and signal processing attacks. This method is intended to provide remedies from the shortcomings of the technique proposed by Lin et al. (2008), and invalidates the effect of intentional attacks recently designed by Meerwald et al. (2009). The algorithm incorporates three level image decomposition using lifting wavelet transform (LWT) and low-pass subband is utilized for data hiding purpose. Watermark bits are embedded into the blocks of non-overlapped wavelet coefficients of the cover image by quantizing the two maximum coefficients of the corresponding block. In watermark extraction process, the DSR is applied by performing the tuning operation on coefficient blocks of attacked watermarked image. It is a parameter dependent approach that enhances the performance of watermark extraction, where the parameters of DSR inherently depend on the image properties such as standard deviation or variance. As far as security is concerned, the randomization of wavelet coefficients, blocks, and watermark bits helps the framework to be more secure. The proposed technique is also examined against multiple watermarking attack and successfully proves its authenticity and ownership. Comparison of the proposed technique with recent techniques shows remarkable improvement in terms of robustness and security against various intentional, signal processing, and geometrical attacks. 相似文献

Stroke is the third major cause of death and foremost cause of disability worldwide. Cerebrovascular stroke remains largely a clinical diagnosis. The use of biomarkers in diagnosing stroke and assessing prognosis is an emerging and rapidly evolving field. The study aimed to investigate the predictive value of neurobiochemical marker of brain damage (neuron-specific enolase [NSE]) with respect to degree of disability at the time of admission and neurological worsening in acute ischemic stroke patients. We investigated 150 patients with cerebrovascular stroke who were admitted within 72 h of onset of stroke in the Department of Neurology at SAIMS. Venous blood samples were taken after admission and NSE was analyzed by solid enzyme linked immunosorbent assay using Analyzer and microplate reader from Biored: Code 680. In all patients, the neurological status was evaluated by a standardized neurological examination and the National Institutes of Health Stroke Scale on admission and on day 7. Serum NSE concentration was found to significantly correlate with both degree of disability and neurological worsening in acute ischemic stroke cases in the present study. The maximum serum NSE level within 72 h of admission was significantly higher in patients with greater degree of disability at the time of admission. Serum NSE levels were also found to be significantly elevated in patients with bad neurological outcome. Our study showed that serum NSE has high predictive value for determining severity and early neurobehavioral outcome after acute stroke. 相似文献

Interdisciplinarity is heralded as a relatively new educational and research paradigm that can effectively address complex problems at disciplinary boundaries. Yet little is known about the extent to which interdisciplinarity has penetrated higher education, nor about how students and program administrators view its usefulness. Through a case study of one field, urban planning, we assessed the extent to which graduate students and program administrators understand and support interdisciplinarity in the departments. We also assessed the extent to which specific factors might affect levels of support. Our survey results suggest differing attitudes between students and administrators and diverse opinions as to whether interdisciplinarity provides a practicable approach to addressing societal challenges. We offer a model for fostering interdisciplinarity and developing empirical evaluations of programs. 相似文献

Serum ferroxidase and albumin levels were determined in 98 patients of tubercuiosis, of whom 49 were freshly diagnosed, sputum
positive (group-I) & 49 were completely treated patients (group-II). Forty nine age and sex matched healthy individuals were
taken as controls. Mean±SD of serum ferroxidase and albumin levels in controls, group-I and group-II was found to be 864.35±106.35
IU/L & 3.91±0.234 g/dL, 1603.76±222.65 IU/L & 3.24±0.518 g/dL and 1001.78±201.63 IU/L & 3.82±0.43 g/dL, respectively. Serum
ferroxidase in group I was significantly higher as compared to controls and group-II (p<0.01). The decreased levels of serum
albumin in group I, as compared to control and group-II was statistically significant (p<0.01). Serum ferroxidase: albumin
ratio (Ferroxidase in International Unit per gram of albumin) in group I (50.47±10.36 IU/g) was significantly higher than
controls (22.22±3.3 IU/g), (p<0.001) while in group II it was significantly lower (26.72±7.18 IU/g, p<0.001) than group-I
and close to control values. Serum ferroxidase: albumin ratio (IU/g) can therefore be incorporated as a surrogate marker to
assist in diagnosis and prognosis of pulmonary tuberculosis. 相似文献

近几年来,我们已经听到太多有关知识产权（IP）的议题,大家对此也都知之甚详.的确,我们都了解IP问题有两个不同的面向--一个是来自许多欧美国家的专利所有权人抱怨其权益受到侵犯,另外则是亚洲地区的业者正积极地建构其专利权资产. 相似文献
