Total Thiols and MDA Levels in Patients with Acute Myocardial Infarction Before and After Reperfusion Therapy
Background: Reactive oxygen species have been implicated in the pathogenesis of ischemic and reperfusion injury. In the current work we have measured malondialdehyde (MDA), total thiols, total CK, CK-MB and AST in ECG proven acute myocardial infarction (AMI) patients immediately after admission and 24 hours after administration of thrombolytic agent streptokinase, and in healthy controls. Methods: Blood samples from 44 AMI patients and 25 age and sex matched healthy controls were obtained and analyzed for MDA, total thiols using spectrophotometric methods and cardiac enzymes CK, CK-MB and AST using automated analyzer. Results: We have found significant increase in MDA, CPK, CK-MB, AST (p< 0.001) and significant decrease in total thiols (p<0.001) in AMI patients after thrombolytic therapy compared to values at admission, and healthy controls. MDA correlated negatively with total thiols (r = - 0.333, p<0.05) and positively with CK-MB (r = 0.491, p<0.01) in AMI patients after thrombolytic therapy. Conclusions: Reperfusion following thrombolytic therapy increases reactive oxygen species with concomitant decrease in antioxidant total thiols
Design of Low Power Vedic Multiplier Based on Reversible Logic
Reversible logic is a new technique to reduce the power dissipation. There is no loss of information in reversible
logic and produces unique output for specified inputs and vice-versa. There is no loss of bits so the power
dissipation is reduced. In this paper new design for high speed, low power and area efficient 8-bit Vedic
multiplier using Urdhva Tiryakbhyam Sutra (ancient methodology of Indian mathematics) is introduced and
implemented using Reversible logic to generate products with low power dissipation. UT Sutra generates partial
product and sum in single step with less number of adders unit when compare to conventional booth and array
multipliers which will reduce the delay and area utilized, Reversible logic will reduce the power dissipation. An
8-bit Vedic multiplier is realized using a 4-bit Vedic multiplier and modified ripple carry adders. The proposed
logic blocks are implemented using Verilog HDL programming language, simulation using Xilinx ISE software
ORGANO PHOSPHORUS COMPOUND POISONING, COMPLICATED ACUTE RENAL FAILURE AND DELAYED POST HYPOXIC ENCEPHALOPATHY - A CASE REPORT
Organophosphorus compound (OPC) poisoning is one of the most common poisons in rural India. We present a 27 year old female patient who came to us in altered sensorium and froathing from mouth with an alleged history of OPC intake about 2 hours back. The patient was intubated, connected to a mechanical ventilator and atropinized. On day 3 of admission patient had elevated renal parameters and was diagnosed as Acute Renal Failure due to acute tubular necrosis probably poison induced. On day 4 of admission she suffered an acute cardiac arrest and was resuscitated; following this she gradually improved and after 3weeks of intensive management her sensorium deteriorated. MRI Brain showed Diffuse Cerebral White Matter Leukodystrophy due to DEMYELINATION (Hypoxia induced).

Role of Hyperspectral imaging for Precision Agriculture Monitoring
In the modern era precision agriculture has started emerging as a new revolution. Remote sensing is generally regarded as one of the most important techniques for agricultural monitoring at multiple spatiotemporal scales. This has expanded from traditional systems such as imaging systems, agricultural monitoring, atmospheric science, geology and defense to a variety of newly developing laboratory-based measurements. The development of hyperspectral imaging systems has taken precision agriculture a step further. Because of the spectral range limit of multispectral imagery, the detection of minute changes in materials is significantly lacking, this shortcoming can be overcome by hyperspectral sensors and prove useful in many agricultural applications. Recently, various emerging platforms also popularized hyperspectral remote sensing technology, however, it comes with the complexity of data storage and processing. This article provides a detailed overview of hyperspectral remote sensing that can be used for better estimation in agricultural applications
Vertical and horizontal gradients in aerosol black carbon and its mass fraction to composite aerosols over the east coast of peninsular India from aircraft measurements
During the Integrated Campaign for Aerosols, gases and Radiation Budget (ICARB) experiment of ISRO-GBP, altitude profiles of mass concentrations of aerosol black carbon (M) and total (composite) aerosols (M) in the lower troposphere were made onboard an aircraft from an urban location, Chennai (13.04 °N, 80.17 °E). The profiling was carried out up to 3 km (AGL) in eight levels to obtain higher resolution in altitude. Besides, to explore the horizontal gradient in the vertical profiles,measurements were made at two levels [500m (within ABL) and 1500m (above ABL)] from ~10 °N to 16°N and ~80 °E to 84°E. The profiles showed a significant vertical extent of aerosols over coastal and offshore regions around Chennai with BC concentrations (~2 μg m) and its contribution to composite aerosols remaining at the same level (between 8 to 10% for FBC) as at the surface. Even though the values are not unusually high as far as an urban location is concerned, but their constancy throughout the vertical column will have important implications to climate impact of aerosols
Trade liberalisation, market power and scale efficiency in Indian industry
Using information on listed firms in each of the industry groups at
the two-digit level within Manufacturing this study investigates whether
the radical shift in trade policy in India in 1991 resulted in a reduction
in market power and/or an improvement in scale efficiency. We estimate
a group-wise production function allowing for firm-specific effects. A
plausible estimate of market power is obtained and the assumption of
constant returns to scale is mostly rejected. As regards the effects of the
trade-policy shock of 1991, evidence of a move to a more competitive
market structure or of an improvement in scale efficiency is not
widespread across Indian manufacturing.

Performance analysis of different matrix decomposition methods on face recognition
Applications using face biometric are ubiquitous in various domains. We propose an efficient method using Discrete Wavelet Transform (DWT), Extended Directional Binary codes (EDBC), three matrix decompositions and Singular Value Decomposition (SVD) for face recognition. The combined effect of Schur, Hessenberg and QR matrix decompositions are utilized with existing algorithm. The discrimination power between two different persons is justified using Average Overall Deviation (AOD) parameter. Fused EDBC and SVD features are considered for performance calculation. City-block and Euclidean Distance (ED) measure is used for matching. Performance is improved on YALE, GTAV and ORL face databases compared with existing methods
Studies on \u3cem\u3eIn Vitro\u3c/em\u3e Antimicrobial Activity of Ethanol Extract of \u3cem\u3eRauvolfia tetraphylla\u3c/em\u3e
The antimicrobial activity of ethanol extract obtained from Rauvolfia tetraphylla was tested against bacterial species of Escherichia coli, Streptococcus lactis, Enterobacter aerogenes, Alcaligenes faecalis, Pseudomonas aeruginosa, Proteus vulgaris, and fungal species of Fusarium oxysporum, Alternaria helianthii, Curvularia lunata, Aspergillus niger, and Penicillium spp. Better antimicrobial activity was observed when the extracts showed maximum activity against E. coli, Enterobacter aerogenes, and Alcaligenes faecalis. Among different fungi tested, A. niger and Penicillium spp were found to be more sensitive to crude extract when compared to others
