Evaluation of Spray Based Routing Approaches in Delay Tolerant Networks

Delay Tolerant Networks (DTN) are mobile ad-hoc networks in which connections are often disruptive or discontinuous. Data forwarding using an appropriate routing strategy is a highly confronting issue in such networks. The traditional ad-hoc routing protocols which require end-to-end connectivity fail to function here due to frequent occurrences of network partitions. Spray and Wait (SaW) routing algorithm is a popular controlled replication based DTN protocol which provides a better delivery performance balancing the average delay and overhead ratio. An empirical analysis of various spray based approaches that have been proposed for DTN has been performed in this paper to compare and evaluate the basic Spray and Wait algorithms (Source Spray and Wait and Binary Sprayand Wait) with some of its major improvements (Spray andFocus, Average Delivery Probability Binary Spray and Wait and Composite methods to improve Spray and Wait). The main aim of this comparative study is to verify the effect of utility metrics in spray based routing protocols over simple spray based approaches. The ONE simulator has been used to provide a simulation environment to evaluate these algorithms and generate results. The performance metrics used are delivery ratio (DR), overhead ratio (OR) and average latency (ALat). The simulation results show that in terms of delivery ratio and average latency, Composite methods to improve Spray and Wait which incorporates delivery predictability metric in the wait phase and also acknowledgements to delete already deliveredmessages from a node’s buffer, outperforms all the other variants compared

  Objective: This study is aimed to extract gum from Abelmoschus esculentus using ultrasonic assisted method and exploring physicochemical, functional, and antioxidant potential of gum for food and pharmaceuticals.Materials and Methods: The extraction of gum from okra was done employing ultrasound-assisted method to improvise the yield. The extracted gum was further characterized for physical properties including swelling index, solubility, water sorption time, packing and flow properties, electrical properties, zeta potential, scanning electron microscopy, and antioxidant activity.Results: The extraction yield of okra fruit gum (OFG) was found to be 31.52%±0.22% (n=3). The OFG powder obtained after lyophilization showed good flow properties as determined from the results of angle of repose (34.21°), Hausner ratio (1.14), and % compressibility (12.5%). An increase in solubility and swelling index of OFG with increase in pH of buffer from 2.0 to 7.4 was observed. The freeze dried OFG possess rough surface and zeta potential of −9.85 mV. Application of derivatized/interacted OFG gum for modification of drug release profiles is concluded from high degree of esterification of 7.8.Conclusion: The result suggest that the antioxidant activity of OFG was higher compared to corn flour gum. Thus, OFG could be utilized as natural antioxidant food ingredients and also for application in medicine and health-care products

Bactericidal Efficacy of Allium sativum (garlic) Against Multidrug Resistant Vibrio cholerae O1 Epidemic Strains

In recent years, emerging trend of antibiotic resistance in Vibrio cholerae associated with cholera epidemics is a matter of serious concern for the management of the disease. Indiscriminate use of antibiotics generally results in selection of antibiotic resistant strains. Introduction of newer antibiotics is a challenging task for the researchers as bacteria soon attain resistance. Therefore, identifying natural compounds of medicinal importance for control of cholera would be the best alternative. Garlic (Allium sativum) was recognised for many centuries in early Chinese, Egyptian and Indian civilisations as an herbal or traditional medicine. In present study, garlic was selected for screening of antimicrobial efficacy against V. cholerae. A total of 55 V. cholerae strains isolated from various outbreaks/epidemics were subjected to antimicrobial testing as per CLSI, USA 2010 guidelines. Antimicrobial screening of garlic extract was performed against all the multidrug resistant strains of V. cholerae. The garlic extracts showed antibacterial activity against all the V. cholerae strains tested, irrespective of their origin, multidrug resistance and virulence. Antibacterial efficacy of garlic on V. cholerae was also evident from in vivo study on sealed adult mice model. Thus, the Garlic extract harnesses the potential to control infection of multidrug resistant V. cholerae, especially in outbreak like situations in remote and under developed areas where drug supply itself is a challeng

Combination of Vatalanib and a 20-HETE Synthesis Inhibitor Results in Decreased Tumor Growth in an Animal Model of Human Glioma

BACKGROUND: Due to the hypervascular nature of glioblastoma (GBM), antiangiogenic treatments, such as vatalanib, have been added as an adjuvant to control angiogenesis and tumor growth. However, evidence of progressive tumor growth and resistance to antiangiogenic treatment has been observed. To counter the unwanted effect of vatalanib on GBM growth, we have added a new agent known as N-hydroxy-N\u27-(4-butyl-2 methylphenyl)formamidine (HET0016), which is a selective inhibitor of 20-hydroxyeicosatetraenoic acid (20-HETE) synthesis. The aims of the studies were to determine 1) whether the addition of HET0016 can attenuate the unwanted effect of vatalanib on tumor growth and 2) whether the treatment schedule would have a crucial impact on controlling GBM. METHODS: U251 human glioma cells (4×10(5)) were implanted orthotopically. Two different treatment schedules were investigated. Treatment starting on day 8 (8-21 days treatment) of the tumor implantation was to mimic treatment following detection of tumor, where tumor would have hypoxic microenvironment and well-developed neovascularization. Drug treatment starting on the same day of tumor implantation (0-21 days treatment) was to mimic cases following radiation therapy or surgery. There were four different treatment groups: vehicle, vatalanib (oral treatment 50 mg/kg/d), HET0016 (intraperitoneal treatment 10 mg/kg/d), and combined (vatalanib and HET0016). Following scheduled treatments, all animals underwent magnetic resonance imaging on day 22, followed by euthanasia. Brain specimens were equally divided for immunohistochemistry and protein array analysis. RESULTS: Our results demonstrated a trend that HET0016, alone or in combination with vatalanib, is capable of controlling the tumor growth compared with that of vatalanib alone, indicating attenuation of the unwanted effect of vatalanib. When both vatalanib and HET0016 were administered together on the day of the tumor implantation (0-21 days treatment), tumor volume, tumor blood volume, permeability, extravascular and extracellular space volume, tumor cell proliferation, and cell migration were decreased compared with that of the vehicle-treated group. CONCLUSION: HET0016 is capable of controlling tumor growth and migration, but these effects are dependent on the timing of drug administration. The addition of HET0016 to vatalanib may attenuate the unwanted effect of vatalanib

Clobetasol propionate 0.025%: a topical therapeutic for skin diseases

The most widely recommended drugs for the treatment of a variety of dermatoses are topical corticosteroids (TC). These medications are approved for the treatment of inflammatory and pruritic manifestations of dermatologic disorders due to their powerful, symptom-relieving impact. Clobetasol propionate (CP) is the most popular TC used to relieve itching, redness, and edema caused by skin disorders. Topical corticosteroids exhibit anti-inflammatory, anti-pruritic, and vasoconstrictive activities. Clobetasol propionate binds to cytoplasmic glucocorticoid receptors and activates glucocorticoid receptor-mediated gene expression, resulting in the production of anti-inflammatory proteins and suppression of the production of inflammatory mediators. The effectiveness, safety, and clinical experience of utilizing CP 0.025% topical therapy for the treatment of various dermatologic disorders are discussed in this case series

Intravenous Formulation of HET0016 Decreased Human Glioblastoma Growth and Implicated Survival Benefit in Rat Xenograft Models

Glioblastoma (GBM) is a hypervascular primary brain tumor with poor prognosis. HET0016 is a selective CYP450 inhibitor, which has been shown to inhibit angiogenesis and tumor growth. Therefore, to explore novel treatments, we have generated an improved intravenous (IV) formulation of HET0016 with HPßCD and tested in animal models of human and syngeneic GBM. Administration of a single IV dose resulted in 7-fold higher levels of HET0016 in plasma and 3.6-fold higher levels in tumor at 60 min than that in IP route. IV treatment with HPßCD-HET0016 decreased tumor growth, and altered vascular kinetics in early and late treatment groups (p \u3c 0.05). Similar growth inhibition was observed in syngeneic GL261 GBM (p \u3c 0.05). Survival studies using patient derived xenografts of GBM811, showed prolonged survival to 26 weeks in animals treated with focal radiation, in combination with HET0016 and TMZ (p \u3c 0.05). We observed reduced expression of markers of cell proliferation (Ki-67), decreased neovascularization (laminin and αSMA), in addition to inflammation and angiogenesis markers in the treatment group (p \u3c 0.05). Our results indicate that HPßCD-HET0016 is effective in inhibiting tumor growth through decreasing proliferation, and neovascularization. Furthermore, HPßCD-HET0016 significantly prolonged survival in PDX GBM811 model
