    Enhanced databases that use the data as a technical use for many applications. In recent efforts, previous efforts have been completely improved to reduce communication conversations. In the firmware system, the basic problem is the privacy of data to perform cryptographic services many times. We analyse the decryption key switch in control and can decrypt multiple code words, which did not increase the size. We start with the calculation of the key component known as the joint encryption system. Instant messaging methods use less effective inefficiency and manage keyboards for maximum numeric use. We have learned a proclamation of coding system that has made a keyboard that has text numbers encrypted rights for representatives of decryption of encrypted words. Our method is compact when comparing the function of high-performance feature saving space when all important control-related distributed versions

    Military personnel with chronic symptoms following blast traumatic brain injury have differential expression of neuronal recovery and epidermal growth factor receptor genes

    Objective: Approximately one-quarter of military personnel who deployed to combat stations sustained one or more blast-related, closed-head injuries. Blast injuries result from the detonation of an explosive device. The mechanisms associated with blast exposure that give rise to traumatic brain injury (TBI), and place military personnel at high risk for chronic symptoms of post-concussive disorder (PCD), post-traumatic stress disorder (PTSD), and depression are not elucidated. Methods: To investigate the mechanisms of persistent blast-related symptoms, we examined expression profiles of transcripts across the genome to determine the role of gene activity in chronic symptoms following blast-TBI. Active duty military personnel with (1) a medical record of a blast-TBI that occurred during deployment (n = 19) were compared to control participants without TBI (n = 17). Controls were matched to cases on demographic factors including age, gender, and race, and also in diagnoses of sleep disturbance, and symptoms of PTSD and depression. Due to the high number of PCD symptoms in the TBI+ group, we did not match on this variable. Using expression profiles of transcripts in microarray platform in peripheral samples of whole blood, significantly differentially expressed gene lists were generated. Statistical threshold is based on criteria of 1.5 magnitude fold-change (up or down) and p-values with multiple test correction (false discovery rate \u3c0.05). Results: There were 34 transcripts in 29 genes that were differentially regulated in blast-TBI participants compared to controls. Up-regulated genes included epithelial cell transforming sequence and zinc finger proteins, which are necessary for astrocyte differentiation following injury. Tensin-1, which has been implicated in neuronal recovery in pre-clinical TBI models, was down-regulated in blast-TBI participants. Protein ubiquitination genes, such as epidermal growth factor receptor, were also down-regulated and identified as the central regulators in the gene network determined by interaction pathway analysis. Conclusion: In this study, we identified a gene-expression pathway of delayed neuronal recovery in military personnel a blast-TBI and chronic symptoms. Future work is needed to determine if therapeutic agents that regulate these pathways may provide novel treatments for chronic blast-TBI-related symptoms

    805-810Paracetamol [acetaminophen (APAP)] toxicity is universal drug induced basis of acute hepatotoxicity. Here, we have induced hepatotoxicity in zebrafish model using acetaminophen and studied protective role of heptamethoxyflavone isolated from the weed Sphaeranthus amaranthoides Burm.f. Acetaminophen depletes antioxidants such as GST, SOD and CAT levels, elevated the hepatic marker enzymes (ALT and AST), induced apoptosis, and caused hepatocyte necrosis. Heptamethoxyflavone treatment showed protective role on zebrafish embryos as well as adults. It enhanced the levels of antioxidant enzymes and normalized the hepatic markers significantly compared the control and acetaminophen induced groups. While the acetaminophen group showed abnormal levels of Bcl-2, bax, TNF-ɑ and caspase-3 in the heptamethoxyflavone treated group showed significant increase in Bcl-2 levels and reduced levels of apoptotic gene expression (bax, TNF-ɑ and Caspase-3). Histological observations with H & E staining in heptamethoxyflavone treated group showed normal texture of liver cells. These observations confirm the protective role of heptamethoxyflavone isolated from Sphaeranthus amaranthoides against the acetaminophen induced hepatotoxicity

    Objective: Callosobruchus chinensis is a major pest that affects mung bean causing severe damage during storage. The objective of the present study is aimed to evaluate the effect of panchagavya in larvicidal activity on C. chinensis and its seed germination was observed. Methods: The methods used in this study were followed by observing the people at a remote village in Chittoor district of Andhra Pradesh. This study is about the traditional knowledge of the use of cow urine in panchagavya described in Ayurveda and its application in seed preservation. Results: The ovicidal activity of panchagavya was remarkably good. The ability of ovicidal (instar) development into an adult beetle was found to be nothing. C. chinensis instar and adult beetle showed 100% mortality when treated with cow urine in small concentrations and good seed germination was observed. Conclusion: Panchagavya is potentially effective and eco-friendly in controlling beetles in grains storage and its enhanced seed germination

    909-915The heterogeneous photocatalytic oxidation of 2,4-dinitrophenol (2,4-DNP) was investigated in aqueous suspensions of TiO2 at the wavelength of 254nm by using an annular flow type photo-reactor with an 8W low-pressure mercury lamp as a UV -light source. For achieving higher photo-degradation efficiencies of 2,4-DNP, optimized conditions like, irradiation time, initial concentration of 2,4-dinitrophenol and catalyst load were established. The effect of oxygen supply and the optimum pH for achieving maximum degradation were also investigated. All the experiments were carried oul ill a batch recirculation mode. Experiments conducted at oxygenated and deoxygenated conditions indicate that the photo-degradation can be carried out through two different mechanisms. Optical density measurement (spectroscopy) was used to study the degradation. At a pH value of 3.5 and 10.5, maximum removal of 99 and 97 per cent was achieved within 3 h of irradiation time with an initial concentration of 4 x 10-4M. </span
