Synthesis and antiviral properties of arabino and ribonucleosides of 1,3-dideazaadenine, 4-nitro-1,3-dideazapurine and diketopiperazine.
TL;DR: Five nucleoside analogs have been screened for antiviral property against HIV‐1, HSV‐1 and 2, parainfluenza‐3, reovirus‐ 1 and many others and it was observed that arabinosides had greater inhibitory action than ribosides.
Journal ArticleDOI
Local energy-based multimodal medical image fusion in curvelet domain
TL;DR: Comparison of the proposed fusion technique based on curvelet transform with other existing spatial and wavelet transform based methods, in terms of visual and quantitative measures show the effectiveness of the method.
Journal ArticleDOI
Multimodal Medical Image Fusion in Dual Tree Complex Wavelet Transform Domain Using Maximum and Average Fusion Rules
Proceedings ArticleDOI
Biorthogonal wavelet transform based image fusion using absolute maximum fusion rule
TL;DR: Experimental results show that the proposed method improves fusion quality by reducing loss of significant information available in individual images as well as Fusion factor, entropy and standard deviation are used as quantitative quality measures of the fused image.
Journal ArticleDOI

TL;DR: While the major function of MtBPL is biotinylation of BCCP, tight binding of biotin/bio-5′AMP by EcBirA is channeled for its repressor activity, open up avenues for understanding the unique features of MountBPL and the role it plays in biotin utilization in M. tuberculosis.
