Integrated Multiple Features for Tumor Image Retrieval Using Classifier and Feedback Methods
AbstractThe content based image retrieval method greatly assists in retrieving medical images close to the query image from a large database basing on their visual features. This paper presents an effective approach in which the region of the object is extracted with the help of multiple features ignoring the background of the object by employing edge following segmentation method followed by extracting texture and shape characteristics of the images. The former is extracted with the help of Steerable filter at different orientations and radial Chebyshev moments are used for extracting the later. Initially the images similar to the query image are extracted from a large group of medical images. Then the search is by accelerating the retrieval process with the help of Support Vector Machine (SVM) classifier. The performance of the retrieval system is enhanced by adapting the subjective feedback method. The experimental results show that the proposed region based multiple features and integrated with classifier and subjective feedback method yields better results than classical retrieval systems
A Low Cost Real Time Embedded Control System Design Using Infrared Signal Processing with Application to Vehicle Accident Prevention
Vehicle accidents are most common if the driving is inadequate. These happen on most factors if the driver is drowsy or if heis alcoholic. Driver drowsiness is recognized as an important factor in the vehicle accidents. It was demonstrated that drivingperformance deteriorates with increased drowsiness with resulting crashes constituting more than 20% of all vehicleaccidents. But the life lost once cannot be re-winded. Advanced technology offers some hope avoid these up to some extent.A car simulator study was designed to collect physiological data for validation of this technology. Methodology for analysisof physiological data, independent assessment of driver drowsiness and development of drowsiness detection algorithm bymeans of sequential fitting and selection of regression models is presented. In this paper proposes an approach towardsdesign of a Low cost real time embedded control system which involves measure and controls the eye blink using sensor. Ascar manufacturers / industrial automotive communities, incorporate intelligent vehicle systems in order to satisfy theconsumer’s ever increasing demand for more assistant systems for comfort, navigation, or communication, to address theissue of increased level of cognitive stress on drivers to the sources of distraction from the most basic task at hand, i.e.,driving the vehicle. Driver’s drowsiness detection systems are actually receiving a large interest in the academic andindustrial automotive communities for their potentiality to reduce fatalities Eye detection is a crucial aspect in many usefulapplications ranging from face recognition / detection to human computer interface for, driver behavior analysis.

A randomized open label parallel group study comparing the safety, effectiveness and adherence between 2% fusidic acid cream versus 1% retapamulin ointment in children with impetigo
Background: Impetigo is a contagious bacterial skin infection that affects both adults and children. Topical antibacterials such as mupirocin and fusidic acid are the most commonly used in both primary and secondary impetigo. Clinical trials have shown high efficacy of retapamulin in the treatment of secondary impetigo. However, its use in primary impetigo is limited. To this purpose, we compared the safety, efficacy and adherence to treatment of fusidic acid with retapamulin in primary impetigo.Methods: A total of 50 patients with a clinical diagnosis of primary impetigo, between 2-12 years of age, having 0.05). Both drugs were well tolerated.Conclusions: Both fusidic and retapamulin showed similar clinical success in patients with primary impetigo. Since fusidic acid has anti-inflammatory property and its treatment is cost-effective, it can be considered as first-line treatment and retapamulin in fusidic acid-resistant impetigo

Population sub-structure and patterns of quantitative variation among the Gollas of Southern Andhra Pradesh, India
This is the published version, also available here: http://digitalcommons.wayne.edu/humbiol/vol73/iss2/9/.Population substructure and biological differentiation was studied among the Golla, a pastoral caste living in the southern areas of Andhra Pradesh (AP) in India, using 11 anthropometric measurements and 20 quantitative dermatoglyphic variables. The data were collected from a sample of 334 adult males drawn from 30 villages distributed in the Chittoor district of AP, who belonged to 8 endogamous subunits of the same caste. Multiple discriminant analysis of the anthropometrics suggests a highly significant degree of discrimination that is consistent with the microgeographic variations of the groups. In contrast, in different sets of dermatoglyphs discrimination is low and generally inconsistent with both the geographic and ethnohistorical affiliations of the groups. These findings are reflected in the FST value for anthropometry, which is more than double the value of dermatoglyphs. The patterns of gene flow as inferred through the regression of phenotypic variance on the distance of groups from the centroid is not generally consistent with the known backgrounds in the case of either dermatoglyphs or anthropometry. It is concluded that at the level of caste substructure representing the lowest level of population hierarchy, the quantitative variables examined here may not portray a complete picture of the historical process of subdivision. The results of this study are not in congruence with those based on another study of 13 short tandem repeat loci on the same set of populations (Reddy et al. 2001), which may provide better insights into the population structure and history of subdivision that are consistent with the known ethnohistorical backgrounds of the populations
HEPATOPROTECTIVE EFFECT OF THE METHANOLIC EXTRACT OF WHOLE PLANT OF BORRERIA ARTICULARIS ON CARBON TETRACHLORIDE INDUCED HEPATOTOXICITY IN ALBINO RATS
The hepatoprotective activity of methanolic extract of Borreria articularis (L.F) F.N. Willams: (Rubiaceae) at doses of 250 mg/kg and 500 mg/kg were evaluated by carbon tetrachloride (CCl4) intoxication in rats. The toxic group which received 25%CCl4inolive oil (1 ml/kg) per oral (p.o), alone exhibited significant increase in serum ALT, AST, ALP, TBlevels. It also exhibited significant (P<0.001) decrease in TP and ALB levels. The groups received pretreatment of Borreria articularis at a dose of 250 and 500 mg/kg b.w.p.o. had reduced the AST, ALT, ALP and TB levels and the effects were compared withstandarddrug(Silymarin100mg/kgb.w.p.o).Thetotal protein (TP) and albumin (ALB) levels were significantly increased in the animalsreceived pretreatment of the extract at the moderate and higher dose levels and the histopathological studies also supported the protective effect of the extract
Triple Band Textile Array Antenna with Enhanced Gain and Low SAR for Off Body Communication Applications
A triple band wearable microstrip patch antenna array has been designed and analyzed in this work. The designed antenna can be operated in ISM, LAES and X-Band with moderate average gain of 4.2 dB. The antenna gain has been improved by constructing array structure of 1X2 and 1X4 with good impedance feeding by quarter wave transformer. The proposed array antennas are providing moderate gain of 5.7 dB (1X2) and 8.3 dB (1X4) with efficiency more than 90% in the operating bands. The antenna model and the array has been constructed on wearable substrate with conductive textile as radiating element in the design for off body wearable communication applications. SAR analysis also providing acceptable values below 1.6 w/kg at triple operating bands with body placement experimentation.  
Androgen Receptor CAG Repeat Polymorphism and Epigenetic Influence among the South Indian Women with Polycystic Ovary Syndrome
The present study was carried out to assess the role of androgen receptor CAG repeat polymorphism and X chromosome inactivation (XCI) pattern among Indian PCOS women and controls which has not been hitherto explored and also to test the hypothesis that shorter CAG alleles would be preferentially activated in PCOS. CAG repeat polymorphism and X chromosome methylation patterns were compared between PCOS and non-PCOS women. 250 PCOS women and 299 controls were included for this study. Androgen receptor CAG repeat sizes, XCI percentages, and clinical and biochemical parameters were measured. The mean CAG repeat number is similar between the cases (18.74±0.13) and controls (18.73±0.12). The obese PCOS women were significantly more frequent in the <18 and >20 CAG repeat category than the lean PCOS women, yielding a highly significant odds (p = 0.001). Among the women with non-random X-inactivation, alleles with <19 repeats were more frequently activated among cases than controls (p = 0.33). CAG repeat polymorphism by itself cannot be considered as a useful marker for discriminating PCOS. We observed a trend of preferential activation of the shorter allele among the PCOS cases with non random XCI pattern. In the obese PCOS women, this microsatellite variation may account for the hyperandrogenicity to a larger extent than the lean PCOS women
