Role of bilirubin, vitamin C and ceruloplasmin as antioxidants in coronary artery disease [CAD]     

V. K. Verma  V. Ramesh  Satyendra Tewari  R. K. Gupta  Nakul Sinha  C. M. Pandey 《Indian journal of clinical biochemistry : IJCB》2005,20(2):68-74

A study has been carried out on 250 CAD patients to see how the serum levels of three antioxidants i.e., Vitamin C, Bilirubin and Ceruloplasmin are related to the CAD risk factors and characteristics in these patients. The number of severe category CAD patients declined by 7–18% with increasing serum levels of the three antioxidants and, triple vessel disease declined by 14–20%. A decline of 39% in Myocardial Infarction (MI) occurred with increasing serum Ceruloplasmin. Serum Ceruloplasmin was significantly lower in the MI group compared to the non MI group CAD patients. There was a steady and a significant decline in the mean values of serum levels of cholesterol, Triglyceride, VLDL cholesterol along with BMI with increasing serum level. The study indicates that with increasing serum levels of the three antioxidants studied, the % MI along with % Triple vessel disease and severity of CAD goes down suggesting that the modifiable risk factors have to be suitably modified in order to maintain a reasonably high level of these antioxidants, as the risk factors are inversely related to the serum antioxidant levels.  相似文献   

LWT–DSR based new robust framework for watermark extraction under intentional attack conditions     

Vivek Singh Verma  Rajib Kumar Jha 《Journal of The Franklin Institute》2017,354(14):6422-6449

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

Antinuclear Antibody Profiling in Patients of a Tertiary Care Centre in Central India     

Prishni Gupta  Pratishtha Agrawal  Neha Rani Verma  Seema Shah  Suprava Patel  Rachita Nanda  Eli Mohapatra 《Indian journal of clinical biochemistry : IJCB》2021,36(3):345

The incidence of autoimmune disorders that includes the connective tissue diseases has seen a rise in India in recent times. Antinuclear antibodies, the telltale sign of systemic autoimmune response, thus can be used as a screening tool and also to support the diagnosis of systemic autoimmune disease. The present retrospective cross- sectional analysis aimed to study the antinuclear antibodies profile (patterns and specific antibody reactivity) amongst suspected cases of auto-immune disorders at a tertiary care teaching hospital. The study retrieved and reviewed reports of 644 patients sent for ANA testing by indirect immunofluorescence assay over a period of 1 year by different specialty departments. Positive samples were further processed for anti-ds-DNA antibody and antibodies to extractable nuclear antigen. Data collected was statistically analysed. ANA pattern positivity was observed in 31% of cases and a positive antibody reactivity was seen in 66% of them. Female predominance (82%) was noted in both pattern positivity and antibody reactivity. High levels of pattern positivity and antibody reactivity was found in the young adults (45.9%). Amongst the ANA patterns, the nuclear homogenous pattern was found the commonest. The common antibodies associated with this pattern were anti-dsDNA and U1 Sm/RNP antibodies. A stronger fluorescence intensity on initial screening showed a higher confirmation rate for specific antibodies on immunoassay. High occurrence of positive ANA patterns in autoimmune disorders suggests its utilization as a screening tool for them and would also play an adjuvant to the diagnosis. Early knowledge about future autoimmunity will earn better prognostic achievements through better treatment interventions.  相似文献

Abstract

The threats to traditional cultural landscapes and the concomitant demands from society for remedial landscape management represent a new challenge for agricultural education. The research described here examined the extent to which relevant landscape management skills and knowledge are transferred to would-be farmers (if at all) within the Austrian agricultural school system. A plurilateral approach was taken, involving a standardised text evaluation of curricula (as defined in legislative documents), examination of further vocational training programmes for teachers, and investigation of the actual teaching situation in selected schools. This combination of methods produced a comprehensive overview of the situation in agricultural schools and academies with regard to landscape management teaching. The teaching programmes prescribed by law and the actual programmes carried out by teachers were compared with a theoretical ‘best-case’ programme for teaching landscape management, and this revealed considerable shortcomings in current teaching. The research also identified potential constraints to the integration of landscape management elements within the agricultural school system.  相似文献

Eco-friendly alternative refrigeration systems     

S. S. Verma 《Resonance》2001,6(10):57-67

Refrigeration applications at the domestic, commercial and industrial levels are becoming an integral part of the present day living. The demand and supply of refrigeration systems is increasing day by day with the changing lifestyle. The existing compressor-based refrigeration (i.e., mechanical refrigeration) system has reached the maximum level of innovation. For the last few decades, there has not been any significant increase in the efficiency (i.e., coefficient of performance, COP) of the system. Moreover, with the increasing awareness of environmental degradation, the production, use and disposal of ChloroFluoro Carbons (CFCs) and HydroChloroFluoroCarbons (HCFCs) as refrigerants in mechanical refrigeration system has become a subject of great concern. However, such systems are being developed using more ecofriendly refrigerants viz., air, CO₂, NH₃, etc. Besides, efforts are being directed to develop other types of refrigeration technologies e.g., magnetic refrigeration, thermoelectric refrigeration (discussed in Part 1) and thermoacoustic refrigeration (discussed in Part 2), which will be moreecofriendly, cost effective, efficient, simple in design, convenient and reliable.  相似文献   

Commentary on Cross‐Cultural Perspectives on Positive Youth Development With Implications for Intervention Research          下载免费PDF全文

Silvia H. Koller  Suman Verma 《Child development》2017,88(4):1178-1182

There is a growing focus on youth positive development issues among researchers and practitioners around the world. In this special issue of Child Development, each of the international authors provides new perspectives and understanding about youth developmental assets in different cultural settings. The present commentary (a) examines some of the cross‐cultural themes that emerge from the four articles by international authors in this issue with implications for positive youth development (PYD) and (b) how intervention science can benefit by incorporating a PYD approach. As evident, youth involved in contexts that provide positive resources from significant others not only were less likely to exhibit negative outcomes, but also were more likely to show evidence of positive development.  相似文献
