In Wireless Sensor Network (WSN), sensor nodes must utilize energy efficiently to increase the life time of a sensor node. Existing protocols for achieving data privacy and integrity in WSN introduce high communication and computational overhead which causes high energy and bandwidth consumption. Using data aggregation in WSN reduces the energy consumption at a sensor node. Existing privacy preserving data aggregation protocols do not provide efficient solutions for energy constrained and security required WSNs due to the overhead of power consuming operations at aggregator nodes. This paper proposes a new scheme called Secure Energy Efficient Homomorphism based Privacy and Integrity Preserving Data Aggregation for WSNs (SEEHPIP) that uses additive homomorphism to achieve confidentiality during data aggregation. It achieves non-delayed data aggregation by performing aggregation on encrypted data. The proposed scheme is best suited for time critical, secure applications since it achieves privacy, integrity, accuracy, end to end confidentiality, data freshness and energy efficiency during data aggregation without introducing a significant overhead on the battery limited sensor nodes. © Research India Publications.

Mobile ad hoc network (MANET) is one of the most important and unique network in wireless network which has brought maximum mobility and scalability. High efficient routing is an important issue in the design of limited energy resource MANETs. In the last few decades many research work have been conducted by the researchers in the field of routing protocols for MANETs. Nowadays the main area of concern is based on routing protocols utilizing the concept of swarm intelligence in which bee inspired routing and ant inspired routing are suggested. But among these two Bee inspired routing has been accepted widely for energy efficient and scalable multipath routing protocol based on dynamic cluster and foraging behavior of a bee swarm. Here in this paper the advantages of Bee inspired routing have been discussed with respect to its architecture and working for choosing the intermediate nodes and different paths by comparing different parameters of all the algorithms from the ant colony optimization and bee colony optimization for energy efficient MANETs where the performance of Bee-AdHoc-C is found to be best. © Research India Publications.

Background: Many risk factors can compromise an older adult’s systemic health. Among the oral ailments in the elderly, root caries is a significant one which causes tooth loss in them. Hence, there is a need to have a baseline data for understanding problem of root caries in elderly population and factors which affect its prevalence.Aims: a)To asses the prevalence of root caries in older individuals in a rural health centre in India. b) To asses the relationship of oral habits with root caries.Methodology: The study included 210 elderly dentate and consenting individuals (123-females, 87-males) aged 55 to 75 y and above. Demographic and health behaviour data were collected through personal interviews. The subjects were examined for root caries. Statistical analyses of the data were done using chi-square and multiple logistic regression analysis.Results: Out of all, 94.76% of elderly patients examined had gingival recession in one or more teeth. The prevalence of root caries was 41.9%. The prevalence of root caries was significantly associated with age, perceived dryness of mouth, smoking, smoking and tobacco chewing and tobacco chewing only (p<0.05). There was significantly higher root caries in the age group of 75 years and above (OR-3.67).Conclusion: It was evident from our study that root caries prevalence was high in elderly population. Age, root surfaces with recession, deleterious oral habits such as smoking, tobacco chewing, and dryness of mouth had a definite effect on the prevalence of root caries. © 2014, Journal of Clinical and Diagnostic Research.

Central odontogenic fibroma is an unusual and controversial odontogenic tumour. We present a case of central odontogenic fibroma involving premolar- molar region of mandibular left quadrant. The lesion was asymptomatic with well defined borders, without resorption and displacement of the adjacent teeth. The case was initially diagnosed as lateral periodontal cyst based on clinical and radiographic findings, but on histopathological diagnosis it turned out to be central odontogenic fibroma. Hence, this case report gives readers a bird's eye view of the significance of role of histopathology in diagnosis. Source

Human Immunodeficiency Virus infection is one of the major health problems worldwide. CD4+Tcell count and viral load have been used as important laboratory parameters to evaluate antiretroviral treatment eligibility. Eligibility for antiretroviral treatment in HIV infected patients is determined either by CD4 +T cell count of < 200cells/μl or clinical diagnosis of WHO stage 3 or 4. Since laboratory set up needed for CD4+Tcell investigations are inadequate in certain under developed countries, there is need to identify low cost clinical tools for assessing antiretroviral treatment eligibility. Hence, study was done to assess whether presence of grey finger nails and oral pigmentation in HIV positive individuals could be used to distinguish between low and high CD4+Tcell count, thus initiate antiretroviral treatment. Finger nails and oral mucosa of 50 HIV infected patients (29 cases < 200 CD4+ Tcells/μl, 21 patients > 200 CD4+T cells/μl) were photographed and evaluated. In our study we found significant co-relation (p < 0.025) of grey finger nails and oral pigmentation with CD4+Tcell count < 200 cells/μl in HIV infected patients. Though not a specific method, occurrence of grey finger nails and oral pigmentation could be a useful alternative clinical tool to assess antiretroviral treatment eligibility in resource limited settings.
