Transfer RNA modifications and modifying enzymes in Saccharomyces cerevisiae
Transfer RNAs are adaptor molecules, which decode mRNA into protein and, thereby, play a central role in gene expression. During the maturation of a...

The biosynthesis and functional roles of methylated nucleosides in eukaryotic mRNA
Modified nucleosides are present in mRNA of all eukaryotes, albeit at much lower levels than in other RNA moieties such as rRNA, tRNA, and snRNA....
-
Biosynthesis and function of tRNA wobble modifications
Post-transcriptional modifications at the first (wobble) position of the tRNA anticodon participate in the precise decoding of the genetic code that...
-
Conserved ribosomal RNA modification and their putative roles in ribosome biogenesis and translation
rRNA maturation requires extensive covalent modifications of riboses and bases. These modifications concern exclusively the most conserved regions of...
-
Biosynthesis and function of 1-methyladenosine in transfer RNA
Determining the function of single nucleotide modifications in tRNA has been elusive because so many tRNA modification enzymes are not essential for...
-
Adenosine to inosine RNA editing in animal cells
Major advances in the understanding of adenosine deaminases acting on RNA (ADARs) have come from the generation of ADAR mutant animals. In mice,...

Elastic and Structural Properties of Carbon Materials Investigated by Brillouin Light Scattering
Brillouin light scattering (BS) is a nondestructive technique exploited to investigate collective excitations in solids: acoustic phonons, spin...
-
Formation, Atomic Structures and Properties of Carbon Nanocage Materials
Various carbon nanocage fullerene materials (clusters, metallofullerenes, onions, nanotubes, nanohorns and nanocapsules) were synthesized by...

Pulsed Laser Deposition of Carbon Films: Tailoring Structure and Properties
Pulsed laser deposition (PLD) is a versatile technique to synthesize films of a given material with strongly different properties. In this chapter we...
-
Correlation Between Local Structure and Film Properties in Amorphous Carbon Materials
A discussion of the various amorphous carbon and amorphous hydrogenated carbon films is presented. A link between sp 2, sp...
-
Measurements of Defect Density Inside CVD Diamond Films Through Nuclear Particle Penetration
Fast nuclear particles (light or heavy ions), passing through a diamond film, deposit energy by ionization. It is possible to collect the developed...
-
Optical Characterisation of High-Quality Homoepitaxial Diamond
Recently, great effort has been devoted to the deposition of homoepitaxial diamond for electronic applications. Its single-crystal nature avoids the...
