The molecular mechanisms mediating herpes simplex virus type 1 (HSv-1) gene silencing during latent infection arenot clear. Five copies of early growth response gene 1 (Egr-1) binding elements were identified in the intron of HSv-1ICP22 (infected cell protein No. 22) gene, leading to the hypothesis that Egr-1 binds to the viral genome and regulates theviral gene expression. Transient co-transfection assays indicated that Egr-1 negatively regulated the transcription of bothfull-length and intron-removed ICP22 promoters. The same assays also revealed that Egr-1 repressed ICP4 (infected cellprotein No. 4) promoter activity in a dose-dependent manner but showed less inhibition when the intron was *** deacetylation was not involved in this regulation since histone deacetylase inhibitor trichostatin Adid not exhibitany effect on Egr-1-mediated repression. Chromatin immunoprecipitation assays showed that Egr-1 reduced the bindingof Spl to the promoters and that the co-repressor Nab2 (NGFI-A/EGR1-binding protein) was recruited to the proximityof ICP4 in the presence of Egr-1. These results suggested that the multifunctional transcription factor Egr-1 can repressHSv-1 immediate-early gene expression through the recruitment of co-repressor Nab2 and reduction of Sp1 occupancy,and thus may play a critical role in HSv-1 gene silencing during latency.

Numerous advancements in the Information Technology (IT) require the proper security policy for the data storage and transfer among the cloud. With the increase in size of the data, the time required to handle the huge-size data is more. An assurance of security in cloud computing suffers various issues. The evolution of cryptographic approaches addresses these limitations and provides the solution to the data preserving. There are two issues in security assurance such as geographical distribution and the multi-tenancy of the cloud server. This paper surveys about the various cryptographic techniques with their key sizes, time required for key/signature generation and verification constraints. The survey discusses the architecture for secure data transmissions among the devices, challenges raised during the transmission and attacks. This paper presents the brief review of major cryptographic techniques such as Rivest, Shamir Adleman (RSA), Dffie Hellman and the Elliptic Curve Cryptography (ECC) associated key sizes. This paper investigates the general impact of digital signature generation techniques on cloud security with the advantages and disadvantages. The results and discussion section existing in this paper investigate the time consumption for key/signature generation and verification with the key size variations effectively. The initialization of random prime numbers and the key computation based on the points on the elliptic curve assures the high-security compared to the existing schemes with the minimum time consumption and sizes in cloud-based applications.

Li−garnet solid-state batteries(SSBs)have attracted a great deal of attention due to their nonflammability,nontoxicity,and potential to achieve significantly higher energy and power densities compared to those of conventional Li-ion batteries.1−5 Research that began in 20076 and focused primarily on improving the Li-ion conductivity of Li7La3Zr2O12(LLZO)has since evolved into the development of Li−garnet SSBs,encompassing aspects of the LLZO/Li interface,7,8 the electrochemical voltage window of LLZO,9−11 and compatibility with current cathode chemistries.12−15 Nevertheless,an analysis of the literature shows that there is still no clear opinion in the research community on the configuration of future Li−garnet *** particular,opinions differ on the design of the LLZO-based anode layer that accounts for(i)the dynamic expansion and shrinkage of the Li metal(from up to 5−25μm for the area capacity of 1−5 mAh cm^(−2))and(ii)the probability of void formation at the Li/LLZO interface.

Filtration efficiency of Ni(II) from aqueous solution using pristine and modified MWCNTs filters was investigated as a function of Ni(II) ion concentration, p H, and filter mass. MWCNTs were synthesized by CvD method and modified using two complementary treatments, purification(using a mixture of hydrochloric acid and hydrogen peroxide) and functionalization(using nitric acid). The effect and mechanism of each treatment on the structural integrity of pristine MWCNTs has been studied. Morphology of the pristine and modified filters was investigated by Raman Spectrometry(RS), Scanning Electron Microscopy(SEM), Energy Dispersive X-ray Spectroscopy(EDS),Fourier Transform Infrared(FTIR) spectrometry and Thermogravimetric analysis. It was found from Raman spectra that the ratio of the intensity of D-band to that of G-band decreased by purification process, and increased by functionalization process. The adsorption mechanism of Ni(II) onto the surface functional groups of modified MWCNTs was confirmed by FTIR spectrum. The filtration results showed that the removal efficiency of Ni(II) is strongly dependent on pH and could reach 85% at pH = 8. Also, modified MWCNT filters can be reused through many cycles of regeneration with high performance. Functionalized MWCNTs filters may be a promising adsorbent candidate for heavy metal removal from wastewater.

To investigate the effect of a low-FODMAP diet on irritable bowel syndrome (IBS)-like symptoms in patients with inflammatory bowel disease (IBD).METHODSThis was a randomised controlled open-label trial of patients with IBD in remission or with mild-to-moderate disease and coexisting IBS-like symptoms (Rome III) randomly assigned to a Low-FODMAP diet (LFD) or a normal diet (ND) for 6 wk between June 2012 and December 2013. Patients completed the IBS symptom severity system (IBS-SSS) and short IBD quality of life questionnaire (SIBDQ) at weeks 0 and 6. The primary end-point was response rates (at least 50-point reduction) in IBS-SSS at week 6 between groups; secondary end-point was the impact on quality of ***-nine patients, 67 (75%) women, median age 40, range 20-70 years were randomised: 44 to LFD group and 45 to ND, from which 78 patients completed the study period and were included in the final analysis (37 LFD and 41 ND). There was a significantly larger proportion of responders in the LFD group (n = 30, 81%) than in the ND group (n = 19, 46%); (OR = 5.30; 95%CI: 1.81-15.55, P ve study, a low-FODMAP diet reduced IBS-like symptoms and increased quality of life in patients with IBD in remission.
