Chetana Vaishnavi, Meenakshi Singh, Jarnail Singh Thakur, Babu Ram Thapa
Advances in Microbiology (AiM) , 2015, DOI: 10.4236/aim.2015.53015
Abstract: Campylobacter is one of the most common bacterial enteropathogens of food borne origin in industrialized countries with C. jejuni being the most common species followed by C. coli. The prevalence of Campylobacters in and around Chandigarh, India was studied by phenotypic and genotypic methods. Fecal samples from 1145 diarrheal patients and 102 healthy subjects from hospital and community were cultured on Campylobacter media and identified by Gram stain, biochemical investigations and serotyping. Molecular identification of Campylobacter isolates was done using specific primers to unique regions of 16S rRNA, Campylobacter jejuni (hipO), Campylobacter coli (aspK), Campylobacter lari (glyA) and Campylobacter upsaliensis (lpxA) genes. Identification of specific genes to look for resistance to nalidixic acid, ciprofloxacin, tetracyclin and streptomycin was also done. Campylobacters were isolated from 2.6% of patients with diarrhea. Campylobacteriosis was more prevalent in children ≤5 years old and during summer season. The most frequent serotypes were S:27, B:2, Z5:52 and V:32. All the Campylobacters isolated by culture were confirmed genotypically by identification of 16S rRNA, hipO and aspK genes. Of the 30 isolates, 27 were C. jejuni and 3 were C. coli. No C. lari or C. upsaliensis were detected. Antibiotic resistance was 40% for nalidixic acid, 23.3% for ciprofloxacin, 50% for tetracyclin and 20% for streptomycin. Campylobacter prevalence is low in the region with C. jejuni being the most common species. A high degree of resistance was found for nalidixic acid and tetracyclin but moderate for ciprofloxacin and streptomycin.

Abstract: objective: to compare the prevalence of underweight as calculated from indian academy of paediatrics (iap) growth curves (based on the harvard scale) and the new who child growth standards. methods: we randomly selected 806 children under 6 years of age from 45 primary anganwadi (childcare) centres in chandigarh, punjab, india, that were chosen through multistage stratified random sampling. children were weighed, and their weight for age was calculated using iap curves and who growth references. nutritional status according to the who child growth standards was analysed using who anthro statistical software (beta version, 17 february 2006). the χ2 test was used to determine statistical significance at the 0.05 significance level. findings: the prevalence of underweight (z score less than -2) in the first 6 months of life was nearly 1.6 times higher when calculated in accordance with the new who standards rather than iap growth curves. for all ages combined, the estimated prevalence of underweight was 1.4 times higher when iap standards instead of the new who standards were used. similarly, the prevalence of underweight in both sexes combined was 14.5% higher when iap standards rather than the new who growth standards were applied (p < 0.001). by contrast, severe malnutrition estimated for both sexes were 3.8 times higher when the new who standards were used in place of iap standards (p < 0.001). conclusion: the new who growth standards will project a lower prevalence of overall underweight children and provide superior growth tracking than iap standards, especially in the first 6 months of life and among severely malnourished children.

Shyamal Koley,Jarnail Singh
Human Biology Review , 2012,
Abstract: The purpose of the present study was to estimate the dominant handgrip strength and its correlations with selected anthropometric and physiological characteristics in inter-university volleyball players. Three anthropometric characteristics, four body composition parameters, two physical and two physiological characteristics were measured on randomly selected 63 inter-university volleyball players (38 males and 25 females) aged 18.25 years from six Indian universities, competition was held in Guru Nanak Dev University, Amritsar, Punjab, India. An adequate number of controls (n = 102, 52 males and 50 females) were also taken from the same place for comparisons. In results, one way analysis of variance showed significant (p . .004 - .000) differences in all the variables between volleyball players and controls. In volley players, significantly positive correlations were found between right and left handgrip strength and all the variables studied except percent body fat (where the correlations were significantly negative). It may be concluded that dominant handgrip strength had some strong positive correlations with all the variables studied in inter-university volleyball players.

Abstract: The purpose of this study was two-fold, firstly, to evaluate the anthropometric profile of Indian interuniversity basketball players and, secondly, to search the correlation of body mass index, % body fat, hand grip strength (right dominant) and Vo2max,with other anthropometric characteristics studied. Eleven anthropometriccharacteristics, four body composition parameters, two physical and two physiological variables were measured on randomly selected 60 inter-university Indian basketball players (35 males and 25 females) aged 18–25 years from Guru Nanak Dev University, Amritsar, Punjab, India with adequate controls (n = 102, 52 males and 50 females). The results indicated that male basketball players were taller (6.63%) and heavier (7.31%) and female basketball players were slightly taller (0.31%) and lighter (3.74%) than their control counterparts. One way analysis of variance showed significant (p ≤ .004 - .000) between group differences in all the variables (excepthip circumference) between basketball players and controls. In basketball players, significantly positive correlations were found with BMI and other 12 variables, with percent body fat and 7 variables, with right hand grip strength and 12 variables and with Vo2max and other 9 variables, and significantly negative correlationswere found with BMI and other 1 variable (% lean body mass), with percent body fat and other 6 variables, with right hand grip strength and other 2 variables and with Vo2max with other 3 variables. The findings of the present study might be useful in future investigation on player selection, talent identification in the game of basketball and its training program development.

International Journal of Computer Science and Management Studies , 2011,
Abstract: The primary goal of future cellular mobilecommunication networks is to provide efficient andcost effective services to mobile users under allenvironments. The major issues that affects the qualityof service and performance in wirelesscommunications systems is scarcity of resources.Hence, efficient resource allocation is prime concernin order to improve the performance of cellularnetworks. Two-Tier cellular system is considered toincrease the channel utilization by sharing channelsbetween two tiers. In this paper a Hybrid ChannelAllocation (HCA) strategy for channel allocation and queuing technique is applied to hierarchical cellular network in order to enhance the performance of the system. The hierarchical cellular system helps better utilization of radio spectrum and application ofqueuing technique further increases efficiency of the system by reducing call blocking and dropping and by increasing number of users in the system.

International Journal of Basic & Clinical Pharmacology , 2012, DOI: 10.5455/2319-2003.ijbcp002112
Abstract: Malaria is one of the deadliest infectious diseases that affects millions of people worldwide including India. As an addition to chemoprophylaxis and other antimalarial interventions malaria vaccine is under extensive research since decades. The vaccine development is more difficult to predict than drug development and presents a unique challenge as already there has been no vaccine effective against a parasite. Effective malaria vaccine could help eliminate and eradicate malaria; there are currently 63 vaccine candidates, 41 in preclinical and clinical stages of development. Vaccines are being designed to target pre-erythrocytic stages, erythrocytic stage or the sexual stages of Plasmodium taken up by a feeding mosquito, or the multiple stages. Two vaccines in preclinical and clinical development target P. falciparum; and the most advanced candidate is the pre-erythrocytic vaccine RTS,S which is in phase-III clinical trials. It is likely that world's first malaria vaccine will be available by 2015 at the country level. More efficacious second generation malaria vaccines are on the way to development. Safety, efficacy, cost and provision of the vaccine to all communities are major concerns in malaria vaccine issue. [Int J Basic Clin Pharmacol 2012; 1(2.000): 60-66]

International Journal of Basic & Clinical Pharmacology , 2013, DOI: 10.5455/2319-2003.ijbcp20130805
Abstract: Background: To evaluate efficacy and safety of ampucare, a polyherbal product, in patients with bedsore. Methods: One hundred patients, either sex, more than 18 years of age, with bedsore were divided in to two groups of 50 each. Group-I- Served as control- povidone iodine solution was applied locally on the bedsore, once daily. Group- II- Treatment group- ampucare lotion was applied locally, once daily. Primary end point was time to wound healing and secondary end point included reduction in wound surface area at day-7 and at treatment completion. Percent patients cured, improved, or treatment failure were noted. Depth of wound, % healing and adverse effects were recorded. Results: Application of ampucare in patients with bedsore resulted in rapid healing as compared to control group. Reduction in wound surface area was significant (p<0.01) in group-II. Maximum gain in thickness of granular tissue was observed in this group. In treatment group 68% patients showed excellent response as compared to 60 % in control group. Ampucare was well tolerated. Conclusions: Ampucare treatment markedly accelerates wound healing in patients with bedsore. [Int J Basic Clin Pharmacol 2013; 2(4.000): 371-374]
Edge Based Region Growing
Rupinder Singh,Jarnail Singh,Preetkamal Sharma,Sudhir Sharma
International Journal of Computer Technology and Applications , 2011,
Abstract: Image segmentation is a decomposition of scene into its components. It is a key step in image analysis. Edge, point, line, boundary, texture and region detection are the various forms of image segmentation. Two of the main image segmentation techniques edge detection and region growing are highly in use for image segmentation.In human visual systems, edges are more sensitive than other picture elements. Edgedetection technique when used alone for image segmentation results in small gaps in edge boundaries. It is sensitive to local variations intensity and the contours obtained are usually not closed. Region growing technique when used alone results in errors in region boundaries and the edge pixels might be joined to any of the neighboring pixels. Edge based region growing corresponds to the optimum image segmentation technique in which the both edge detection approach and region growing approach is integrated. This technique is based on the fact that edge based and region based approaches are complementary to each other and use ancillary information to guide the segmentation procedure. This segmentation procedure separates the image in two segments namely background andforeground. The algorithm described here is for integrating edges and regions. Firstly, the edge map of image is obtained by using canny edge operator. Then the edge region is grown. Very small regions are removed by merging. Thus the effect of noise is completely eliminated. The two types of seeds (pixels) hot and cold are obtained in the edge region and according to the type of data being analyzed and application area, the image is segmented into background andforeground objects. It offers very precise segmentation in detecting objects of different sizes and also non-rigid targets. This approach is not sensitive to the parameters, such as the sizes of different operators and thresholds in the edge detection and edge region detection.The algorithm is implemented in MATLAB and the result demonstrates that the algorithm is robust, satisfying and work well for images with non-uniform illumination.
