Analysis on Smooth Handoff in NEMO Route Optimization Protocols
Abstract: With existing Network Mobility Basic Support (NEMO BS) protocol, entire transmissions are completely handled via Mobile Router (MR) to its home network on behalf of all Mobile Network nodes (MNNs) during movement among different networks. This concerns in enlarged length of route with higher delay and loss in best cases. Hence, in order to overcome these constraints, applying Smooth Handoff (SH) technique in Route Optimization (RO) for NEMO is an optimal solution. Consequently, the main aim of this paper is to offer a constructive analysis by doing analysis on some of the current approaches on soft handoff for RO in NEMO as well as discuss their strengths and weaknesses concerning delay and packet loss with some open issues

VIBRATIONAL CIRCULAR DICHROISM SPECTRA AND NORMAL MODE ANALYSES OF THF
Author Institution: Department of Chemistry, University of Illinois at ChicagoWe have measured the vibrational circular dichroism (VCD) spectrum of -tetrahydrofuran (-THF) using an FTIR spectrometer. These spectra were broad and weak compared to previously studied isotopically chiral molecules but reliable features could be identified for several mid-ir bands. To interpret these spectra, a new force field for THF was developed based on an ab initio calculated force field with symmetry. For comparison, force fields with and symmetries were also calculated. The geometry is calculated to be lowest in energy, and that force field gives the best fit after scaling to the ir and Raman data we have re-obtained from five isotopomers. Calculated VCD spectra obtained using Stephen's a priori model agree with experiment for many but not all modes. Fixed partial charge results are worse

The hydrogen sulfide-releasing compounds "ATB-346 and Diallyltrisulfide" attenuate Streptozotocin induced cognitive impairment, neuro-inflammation and oxidative stress in rats: involvement of Asymmetric dimethylarginine
Hydrogen sulfide (H2S) has attracted interest as a gaseous mediator involved in diverse processes in the nervous system, particularly with respect to learning and memory. However, its therapeutic potential in Alzheimer disease (AD) is not fully explored. Therefore, the effect of H2S-releasing compounds against AD like behavioural and biochemical abnormalities was investigated. Memory deficit was induced by intracerberoventicular injection of Streptozotocin (STZ, 3mg/kg). Animals were randomly assigned into 5 groups (12 rats each): normal control, STZ and 3 drug treated groups receiving Naproxen, H2S-releasing naproxen (ATB-346), and Diallyltrisulfide in 20, 32, 40 mg/kg/day, respectively. Memory function was assessed by passive avoidance and T-maze tasks. After 21 days, hippocampal IL-6, malondialdehyde, reduced glutathione (GSH), Asymmetric dimethylarginine (ADMA), and acetylcholinestrase activity were determined. ATB-346 and Diallyltrisulfide ameliorated behavioural performance and reduced malondialdehyde, ADMA and acetylcholinestrase activity while increased GSH. This study demonstrates the beneficial effects of H2S release in STZ-induced memory impairment by modulation of neuro-inflammation, oxidative stress and cholinergic function. It also delineates the implication of ADMA to the cognitive impairment induced by STZ. These findings draw the attention to H2S-releasing compounds as new candidates for treating neurodegenerative disorders which have prominent oxidative and inflammatory components as AD.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
