Electrospinning and Post-Spun Chain Conformations of Synthetic, Hydrophobic Poly(α-amino acid)s. [PDF]
, 2020 Electrospinning and post-spun conformations of hydrophobic poly(α-amino acid)s are described in this study. The poly(α-amino acid)s, poly(Gly), poly(L-Ala), poly(L-Val), and poly(L-Leu) were synthesized via corresponding N-carboxy-a-amino acid anhydrides.

Mechanical properties and chemical stability of pivalolactone-based poly(ether ester)s [PDF]
, 1994 The processing, mechanical and chemical properties of poly(ether ester)s, prepared from pivalolactone (PVL), 1,4-butanediol (4G) and dimethyl terephthalate (DMT), were studied. The poly(ether ester)s could easily be processed by injection moulding, owing

The use of aluminum trialkoxide for synthesis of poly (ε-caprolactone) and poly (δ-valerolactone): A comparative study [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2018 Four aluminum(III) trialkoxides, namely Al(III) ethoxide (1), Al(III) isopropoxide (2), Al(III) tert-butoxide (3), and Al(III) sec.-butoxide (4), were employed as initiators for the bulk ring-opening polymerizations of δ-valerolactone (VL) and ...

Genome Biology, 2019 Background Polyadenylation plays a key role in producing mature mRNAs in eukaryotes. It is widely believed that the poly(A)-binding proteins (PABs) uniformly bind to poly(A)-tailed mRNAs, regulating their stability and translational efficiency.

Poly A- transcripts expressed in HeLa cells. [PDF]
PLoS ONE, 2008 Transcripts expressed in eukaryotes are classified as poly A+ transcripts or poly A- transcripts based on the presence or absence of the 3' poly A tail.

The Dynamic Poly(A) Tail Acts as a Signal Hub in mRNA Metabolism
Cells, 2023 In eukaryotes, mRNA metabolism requires a sophisticated signaling system. Recent studies have suggested that polyadenylate tail may play a vital role in such a system.

Nanopore native RNA sequencing of a human poly(A) transcriptome
bioRxiv, 2018 High-throughput complementary DNA sequencing technologies have advanced our understanding of transcriptome complexity and regulation. However, these methods lose information contained in biological RNA because the copied reads are often short and ...

Raman depolarization ratios in RNA and DNA are sensitive for sugar-base coupling [PDF]
, 1995 Polarized and depolarized Raman spectra are obtained for a number of synthetic polynucleotides containing adenine, uracil, and thymine bases. The depolarization ratios are determined by two methods: (1) by dividing the -spectrum by the -spectrum and (2 ...

Acoustical investigation of poly(dA).poly(dT), poly[d(A-T)].poly[d(A-T)], poly(A) . poly(U) and DNA hydration in dilute aqueous solutions [PDF]
Nucleic Acids Research, 1989 Apparent molar adiabatic compressibilities and apparent molar volumes of poly[d(A-T)].poly[d(A-T)], poly(dA).poly(dT), DNA and poly(A).poly(U) in aqueous solutions were determined at 1 degree C. The change of concentration increment of the ultrasonic velocity upon replacing counter ion Cs+ by the Mg2+ ion was also determined for these polymers.

iCLIP analysis of RNA substrates of the archaeal exosome
BMC Genomics, 2020 Background The archaeal exosome is an exoribonucleolytic multiprotein complex, which degrades single-stranded RNA in 3′ to 5′ direction phosphorolytically. In a reverse reaction, it can add A-rich tails to the 3′-end of RNA.
