Provides the main bibliographic forms of literature cited. Nonserial publications i.e. books, published from U.K. and periodicals from U.S.A. are mostly cited. Ranked list of periodicals, books and authors shows that Modern Fiction Studies and Times Literary Supplement are most preferred journals, whereas, American Fiction and Main Currents in American Thoughts are most frequently cited books. Amongst the first ten most cited authors, six are from USA and two each are from UK and India. English citations account for 99% and only one percent of the citations are shared by the two other languages, namely, Marathi and Sanskrit. Country wise distribution of periodicals and chronological distribution of citations indicate substantial use of older literature with a half-life value of 27.5 years. Authorship study indicates increasing trend towards multiple authorship. The data under study do not exactly fit into the Bradford's Law of Scattering.</span

Synthesis of a Morpholino Nucleic Acid (MNA)-Uridine Phosphoramidite, and Exon Skipping Using MNA/2′-O-Methyl Mixmer Antisense Oligonucleotide

In this study, we synthesised a morpholino nucleoside-uridine (MNA-U) phosphoramidite and evaluated the potential of a MNA-modified antisense oligonucleotide (AO) sequences to induce exon 23 skipping in mdx mouse myotubes in vitro towards extending the applicability of morpholino chemistry with other nucleotide monomers. We designed, synthesised, and compared exon skipping efficiencies of 20 mer MNA-modified 2′-O-methyl RNA mixmer AO on a phosphorothioate backbone (MNA/2′-OMePS) to the corresponding fully modified 2′-O-methyl RNA AO (2′-OMePS) as a control. Our results showed that the MNA/2′-OMePS efficiently induced exon 23 skipping. As expected, the 2′-OMePS AO control yielded efficient exon 23 skipping. Under the applied conditions, both the AOs showed minor products corresponding to exon 22/23 dual exon skipping in low yield. As these are very preliminary data, more detailed studies are necessary; however, based on the preliminary results, MNA nucleotides might be useful in constructing antisense oligonucleotides

pi-Face selectivities in nucleophilic additions to 2-endo aryl-norbornan-7-ones: The role of through-space electrostatic interactions

Experimental diastereoselectivities in hydride reduction of 2-endo-arylnorbornan-7-ones and computed transition state energetics reveal that the facial selectivity in these systems is predominantly determined by repulsions between the approaching nucleophile and the electron cloud of the aryl ring

Guiding the osteogenic fate of mouse and human mesenchymal stem cells through feedback system control

Stem cell-based disease modeling presents unique opportunities for mechanistic elucidation and therapeutic targeting. The stable induction of fate-specific differentiation is an essential prerequisite for stem cell-based strategy. Bone morphogenetic protein 2 (BMP-2) initiates receptor-regulated Smad phosphorylation, leading to the osteogenic differentiation of mesenchymal stromal/stem cells (MSC) in vitro; however, it requires supra-physiological concentrations, presenting a bottleneck problem for large-scale drug screening. Here, we report the use of a double-objective feedback system control (FSC) with a differential evolution (DE) algorithm to identify osteogenic cocktails of extrinsic factors. Cocktails containing significantly reduced doses of BMP-2 in combination with physiologically relevant doses of dexamethasone, ascorbic acid, beta-glycerophosphate, heparin, retinoic acid and vitamin D achieved accelerated in vitro mineralization of mouse and human MSC. These results provide insight into constructive approaches of FSC to determine the applicable functional and physiological environment for MSC in disease modeling, drug screening and tissue engineering
